Effect of duodenal-jejunal bypass on diabetes in the early postoperative period,
Scientific Reports, Vol.13, No.1, 1856-1856, 2023年.

(要約): <jats:title>Abstract</jats:title><jats:p>Metabolic surgery is an effective treatment for patients with type 2 diabetes mellitus (T2DM). The aim of this study was to investigate the effect of duodenal-jejunal bypass (DJB) in a rat model of T2DM during the early postoperative period. A rat model of non-obese T2DM was allocated to two groups: a sham group and a DJB group. On postoperative day 1 (1POD), oral glucose tolerance testing (OGTT) was performed and the changes of glucose transporter expressions in the small intestine was evaluated. [18F]-fluorodeoxyglucose ([18]-FDG) uptake was measured in sham- and DJB-operated rats using positron emission tomography-computed tomography (PET-CT). DJB improved the glucose tolerance of the rats on 1POD. The expression of sodium-glucose cotransporter 1 (SGLT1) and glucose transporter 1 (GLUT1) was high, and that of GLUT2 was low in the alimentary limb (AL) of rats in the DJB group. PET-CT showed that [18F]-FDG uptake was high in the proximal jejunum of DJB-operated rats. These results may show that DJB improve glucose tolerance in very early postoperative period as the result of glucose accumulation in the AL because of changes in glucose transporter expression.</jats:p>

Four cases of gastric adenocarcinoma and proximal polyposis of the stomach treated by robotic total gastrectomy,
Surgical Case Reports, Vol.8, No.1, 70, 2022.

(要約): Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare disease and characterized by a unique point mutation in the promoter 1B region of the adenomatous polyposis coli (APC) gene. There are two aims in surgery for GAPPS; the first is prophylactic gastrectomy, and the second is excising concurrent cancer. We performed robotic total gastrectomy (RTG) for four cases of GAPPS. Case 1 was a woman in her 40 s whose sister had died from gastric cancer. Mutational analysis revealed mutation of APC exon 1B. We performed prophylactic gastrectomy. Case 2 was a woman in her 30 s who had a mutation of APC exon 1B, and preoperative biopsy revealed suspected adenocarcinoma. Case 3 was a woman in her 40 s who was diagnosed with gastric cancer with multiple polyps in the stomach and a mutation of APC exon 1B. Case 4 was a woman in her 20 s in whom biopsy revealed low-grade dysplasia of a raised lesion. She had a mutation in APC exon 1B. We performed RTG with D1 + lymphadenectomy in all patients, and there were no intraoperative complications. Patients with GAPPS are mainly followed regularly with repeat biopsy, and tumors are detected in an early stage. As the safety of robotic surgery for the early gastric cancer is reported, RTG is an option for these patients. This is the first report of RTG for GAPPS patients.

Preoperative evaluation to determine the difficulty of No. 6 lymphadenectomy in laparoscopic gastrectomy.,
BMC Surgery, Vol.24, No.1, 69, 2024.

(要約): Laparoscopic gastrectomy (LG) requires a long learning curve because of the complicated surgical procedures. Infrapyloric (No. 6) lymph node dissection (LND) is one of the difficult procedures in LG, especially for trainees. This study investigated the impact of the prediction of the difficulty of No. 6 LND. We retrospectively reviewed the preoperative computed tomography (CT) images and individual operative video records of 57 patients who underwent LG with No. 6 LND to define and predict the No. 6 LND difficulty. To evaluate whether prediction of the difficulty of No. 6 LND could improve surgical outcomes, 48 patients who underwent laparoscopic distal gastrectomy were assessed (30 patients without prediction by a qualified surgeon and 18 patients with prediction by a trainee). The anatomical characteristic that LND required > 2 cm of dissection along the right gastroepiploic vein was defined as difficulty of No. 6 LND. Of the 57 LG patients, difficulty was identified intraoperatively in 21 patients (36.8%). Among the several evaluated anatomical parameters, the length between the right gastroepiploic vein and the right gastroepiploic artery in the maximum intensity projection in contrast-enhanced CT images was significantly correlated with the intraoperative difficulty of No. 6 LND (p < 0.0001). Surgical outcomes, namely intraoperative minor bleeding, postoperative pancreatic fistula, and drain amylase concentration were not significantly different between LG performed by a trainee with prediction compared with that by a specialist without prediction. Preoperative evaluation of the difficulty of No. 6 LND is useful for trainees, to improve surgical outcomes.

Role of stromal PD-L1 expression in colorectal liver metastasis.,
BMC Cancer, Vol.24, No.1, 97, 2024.

(要約): The outcomes of immune checkpoint blockade for colorectal cancer (CRC) treatment are unsatisfactory. Furthermore, the efficacy of immune checkpoint blockade for liver metastasis of various cancer is poor. Here, we investigated the relationship between stromal programmed death-ligand 1 (PD-L1) expression and the prognosis of patients with colorectal cancer liver metastasis (CRLM). The present study enrolled 84 CRLM patients who underwent surgery (R0) for CRC. Immunohistochemistry was performed to analyze stromal PD-L1 expression in CRLM. Stromal PD-L1 was expressed in 52.3% of CRLM samples, which was associated with fewer not optimally resectable metastases (p = 0.04). Stromal PD-L1 also tended to associate with a lower tumor grade (p = 0.08). Stromal PD-L1-positive patients had longer overall survival (p = 0.003). Multivariate analysis identified stromal PD-L1 expression (p = 0.008) and poorer differentiation (p < 0.001) as independent prognostic indicators. Furthermore, stromal PD-L1 expression was correlated to a high number of tumor-infiltrating lymphocytes (TILs). Stromal PD-L1- and low TIL groups had shorter OS than stromal PD-L1 + and high TIL groups (46.6% vs. 81.8%, p = 0.05) Stromal PD-L1-positive patients had longer disease-free survival (DFS) (p = 0.03) and time to surgical failure (p = 0.001). Interestingly, stromal PD-L1 expression was positively related to the desmoplastic subtype (p = 0.0002) and inversely related to the replacement subtype of the histological growth pattern (p = 0.008). Stromal PD-L1 expression may be a significant prognostic marker for CRLM.

Conversion surgery after successful response to chemotherapy (S-1 + oxaliplatin + nivolumab) in a patient with stage IV gastric cancer with peritoneal metastasis (P1, CY1): a case report.,
International Cancer Conference Journal, Vol.13, No.1, 11-16, 2023.

(要約): We here present a case report of a patient with Stage IV gastric cancer with peritoneal metastasis (P1, CY1) who underwent conversion surgery after a successful response to chemotherapy (S-1 + oxaliplatin + nivolumab). The patient was a woman in her 60 s. Her chief complaint was epigastric pain. Upper gastrointestinal endoscopy showed Type 4 advanced carcinoma on the lesser curvature of the gastric body. Biopsy showed Group 5 (poorly differentiated adenocarcinoma) and HER2 was negative. Staging laparoscopy revealed seeding in the round ligament of the liver (P1) and adenocarcinoma cells in ascites (CY1). Ten courses of chemotherapy (S-1 + oxaliplatin + nivolumab) were administered, after which contrast-enhanced computed tomography showed that the primary tumor had shrunk and seeding was no longer detectable. Upper gastrointestinal endoscopy revealed scar-like changes. A second staging laparoscopy revealed that ascites cytology was negative and a biopsy of the round ligament of the liver showed no malignant cells (P0, CY0). Conversion surgery comprising laparoscopic total gastrectomy with D2 lymph node dissection and resection of the round ligament of the liver was performed. The postoperative course was uneventful. Histopathological examination of the resected specimen revealed no tumor cells in the gastric mesentery or the round ligament of the liver. The pathological diagnosis was gastric cancer [M, U, L, Less, Ant, Post, type4, T3(SS), N0, M0 (H0, P0, CY0), ypStage IIA]. Adjuvant chemotherapy (S-1) was commenced. The patient is still alive 7 months later with no evidence of recurrence.

Visualization of the pelvic nerves using magnetic resonance imaging for rectal cancer surgery.,
Surgical Endoscopy, Vol.37, No.6, 4315-4320, 2023.

(要約): This study evaluated the visualization of the pelvic nerves using magnetic resonance imaging (MRI) combined with computed tomography (CT) to synthesize three-dimensional (3D) reconstruction images of the pelvic organs. The CT and MRI scans were performed for patients with rectal cancer who underwent surgery. The out-of-phase image of LAVA-Flex was used to identify the pelvic nerves. The images of the pelvic nerves were extracted from the MRI scans, and those of the arteries and rectum and pelvis were extracted from the CT scans. Each extracted organ image was used to synthesize 3D reconstruction images. The MRI scan allowed adequate visualization of the pelvic splanchnic nerves, inferior hypogastric plexus, and obturator nerves. The comparison of 3D reconstruction images and intraoperative findings showed matched images. We visualized the pelvic nerves using MRI and synthesized 3D reconstruction images of the pelvic organs. Preoperative confirmation of the location of the pelvic organs is important to prevent unanticipated injury during rectal cancer surgery.

Utility of robotic surgery for Siewert type II/III adenocarcinoma of esophagogastric junction: transhiatal robotic versus laparoscopic approach.,
BMC Surgery, Vol.23, No.1, 128, 2023.

(要約): Robotic surgery (RS) has been rapidly adopted for gastric cancer and adenocarcinoma of the esophagogastric junction (AEG). However, the utility of RS for Siewert type II/III AEG remains unclear. Forty-one patients who underwent either transhiatal RS (n = 15) or laparoscopic surgery (LS) (n = 26) for Siewert type II/III AEG were enrolled in this study. The surgical outcomes of the two groups were compared. In the entire cohort, there were no significant intergroup differences in the operative time, blood loss volume, or number of retrieved lymph nodes. The length of the postoperative hospital stay was shorter in the RS group than in the LS group (14.20 ± 7.10 days vs. 18.73 ± 17.82 days, respectively; p = 0.0388). The morbidity rate (Clavien-Dindo grade ≥ 2) was similar between the groups. In the Siewert II cohort, there were no significant intergroup differences in short-term outcomes. In the entire cohort, there was no significant difference between the RS and LS groups in the 3-year overall survival rate (91.67% vs. 91.48%, N.S.) or 3-year disease-free survival rate (91.67% vs. 91.78%, N.S.), respectively. Likewise, in the Siewert type II cohort, there was no significant difference between the RS and LS groups in the 3-year overall survival rate (80.00% vs. 93.33%, N.S.) or 3-year disease-free survival rate (80.00% vs. 94.12%, N.S.), respectively. Transhiatal RS for Siewert II/III AEG was safe and contributed to similar short-term and long-term outcomes compared with LS.

The application of enhanced recovery after surgery in total gastrectomy: a propensity score-matched analysis.,
World Journal of Surgical Oncology, Vol.21, No.1, 148, 2023.

(要約): This study aimed to investigate the feasibility and safety of our enhanced recovery after surgery protocol including early oral intake and omitting nasogastric tube (NGT) placement after total gastrectomy. We analyzed 182 consecutive patients who underwent total gastrectomy. The clinical pathway was changed in 2015, and patients were divided into 2 groups (conventional group and modified group). Postoperative complications, bowel movement, and postoperative hospital stays were compared in the two groups in all cases and propensity score matching (PSM). Flatus and defecation were significantly earlier in the modified group compared with those in the conventional group (flatus: 2 (1-5) days vs 3 (2-12) days, p = 0.03; defecation: 4 (1-14) days vs 6 (2-12) days p = 0.04). The postoperative hospital stay was 18 (6-90) days in the conventional group and 14 (7-74) days in the modified group (p = 0.009). Days until discharge criteria were met were earlier in the modified group compared with that in the conventional group (10 (7-69) days vs 14 (6-84) days p = 0.01). Overall and severe complications occurred in nine patients (12.6%) and three patients (4.2%) in the conventional group and twelve patients (10.8%) and four patients (3.6%) in the modified group, respectively (p = 0.70 and p = 0.83) in all cases. In PSM, there is no significant difference between the two groups concerning the postoperative complications (overall complication 6 (12.5%) vs 8 (16.7%) p = 0.56, severe complications 1 (2%) vs 2 (4.2%) p = 0.83). Modified ERAS for total gastrectomy may be feasible and safe.

Transanal lateral lymph node dissection with intraoperative hologram support in low rectal cancer.,
Surgical Endoscopy, Vol.37, No.7, 5414-5420, 2023.

(要約): In Japan, the standard treatment for stage II/III advanced low rectal cancer is total mesorectal excision plus lateral lymph node dissection (LLND). There are also recent reports on the use of transanal LLND. However, the transanal anatomy is difficult to understand, and additional support tools are required to improve the surgical safety. The present study examined the utility of holograms with mixed reality as an intraoperative support tool for assessing the complex pelvic anatomy. Polygon (stereolithography) files of patients' pelvic organs were created and exported from the SYNAPSE VINCENT imaging system and uploaded into the Holoeyes MD virtual reality software. Three-dimensional images were automatically converted into patient-specific holograms. Each hologram was then installed into a head mount display (HoloLens2), and the surgeons and assistants wore the HoloLens2 when they performed transanal LLND. Twelve digestive surgeons with prior practice in hologram manipulation evaluated the utility of the intraoperative hologram support by means of a questionnaire. Intraoperative hologram support improved the surgical understanding of the lateral lymph node region anatomy. In the questionnaire, 75% of the surgeons answered that the hologram accurately reflected the anatomy, and 92% of the surgeons answered that the anatomy was better understood by simulating the hologram intraoperatively than preoperatively. Moreover, 92% of the surgeons agreed that intraoperative holograms were a useful support tool for improving the surgical safety. Intraoperative hologram support improved the surgical understanding of the pelvic anatomy for transanal LLND. Intraoperative holograms may represent a next-generation surgical tool for transanal LLND.

Stapler insertion angle toward the esophagus reduces the incidence of early postoperative Roux stasis syndrome after distal gastrectomy in minimally invasive surgery.,
BMC Surgery, Vol.23, No.1, 54, 2023.

(要約): Roux stasis syndrome (RSS) after Roux-en-Y (RY) reconstruction significantly prolongs the hospital stay and decreases the quality of life. The purpose of the present study was to evaluate the incidence of RSS in patients who underwent distal gastrectomy for gastric cancer and to identify the factors related to the development of RSS after mechanical RY reconstruction in minimally invasive surgery (MIS). This study included 134 patients who underwent distal gastrectomy in MIS with mechanical RY anastomosis. RSS was defined as the presence of symptoms such as nausea, vomiting, or abdominal fullness, and the confirmation of delayed gastric emptying on imaging or gastrointestinal fiber testing. Clinical data were checked, including body mass index, operative procedure, age, sex, operative time, blood loss volume, extent of lymph node dissection, final stage, stapler insertion angle, method of entry hole closure. The relationship between the incidence of RSS and these factors was analyzed. RSS occurred in 24 of 134 patients (17.9%). RSS occurred significantly more frequently in patients with D2 lymphadenectomy than in patients with D1 + lymphadenectomy (p = 0.04). All patients underwent side-to-side anastomosis via the antecolic route. The incidence of RSS was significantly greater in patients with a stapler insertion angle toward the greater curvature (n = 20, 22.5%) versus the esophagus (n = 4, 8.9%) (p = 0.04). The multivariate logistic regression model revealed that the stapler insertion angle to the greater curvature is identified as independent risk factor for RSS (OR 3.23, 95%Cl 1.01-10.3, p = 0.04). Stapler insertion angle toward the esophagus may reduce the incidence of early postoperative RSS rather than toward the greater curvature.

Cells, Vol.12, No.4, 612, 2023.

(要約): Lenvatinib is a multi-kinase inhibitor approved as a first-line treatment for patients with unresectable advanced hepatocellular carcinoma (HCC). However, its response rate is unsatisfactory, primarily due to the acquisition of resistance, which limits its clinical significance for treating patients with HCC. Recent evidence suggests that epidermal growth factor receptor (EGFR) activation can trigger Lenvatinib-resistance; and is considered an important therapeutic target in HCC. Curcumin, one of the most studied naturally occurring botanicals with robust anti-cancer activity, is also reported to be a potent tyrosine kinase inhibitor. In this study, we hypothesized that the anti-EGFR potential of Curcumin might help overcome Lenvatinib resistance in HCC. We established two Lenvatinib-resistant cells and discovered that a combination of Curcumin and Lenvatinib exhibited a synergistic anti-tumor efficacy in the resistant HCC cell lines. In line with previous reports, Lenvatinib-resistant cell lines revealed significant activation of the EGFR, and genomewide transcriptomic profiling analysis identified that the PI3K-AKT pathway was associated with Lenvatinib resistance. The combination treatment with Curcumin and Lenvatinib dramatically suppressed gene and protein expression of the EGFR-PI3K-AKT pathway, suggesting Curcumin overcomes Lenvatinib resistance via inhibition of EGFR. We further validated these findings in tumor spheroids derived from resistant cell lines. In conclusion, we, for the first time, report that Curcumin reverses Lenvatinib resistance in HCC, and that their combination has clinical application potential for adjunctive treatment in HCC.

Pleomorphic type undifferentiated gastric sarcoma, report of a case.,
Clinical Journal of Gastroenterology, Vol.16, No.1, 20-25, 2023.

(要約): Reports on pleomorphic type of undifferentiated sarcoma (PUS) originating from the gastrointestinal tract, especially the stomach, are extremely rare. We herein report a case of pleomorphic type undifferentiated gastric sarcoma. The patient was a 67-year-old woman. The chief complaint was upper abdominal pain. Upper gastrointestinal endoscopy, ultrasonography, and contrast-enhanced computed tomography showed two submucosal tumors at the greater curvature of the fundus and the lesser curvature of the gastric angle. Endoscopic ultrasound-guided fine-needle aspiration revealed a c-kit-negative spindle cell tumor at the greater curvature of the fundus. Total gastrectomy, splenectomy, and partial resection of the diaphragm and liver were performed. One lesion had invaded the lateral segment of the liver, left diaphragm and spleen. The postoperative course was uneventful. Histopathological and immunohistochemical examinations of the resected specimen revealed PUS. Peritoneal dissemination was detected at 8 months after surgery. However, no effective therapeutic agents were adopted for chemotherapy. The patient had poor performance status due to disease progression and underwent best supportive care. The patient died 10 months after surgery. This case highlights the imaging, histological diagnosis, and treatment strategy for PUS originating from the stomach. Surgeons should be aware of PUS as a differential diagnosis in cases with submucosal tumor of the stomach.

An exosome-based liquid biopsy signature for pre-operative identification of lymph node metastasis in patients with pathological high-risk T1 colorectal cancer.,
Molecular Cancer, Vol.22, No.1, 2, 2023.

(要約): According to current guidelines, more than 70% of patients with invasive submucosal colorectal cancer (T1 CRC) undergo a radical operation with lymph node dissection, even though only ~ 10% have lymph node metastasis (LNM). Hence, there is imperative to develop biomarkers that can help robustly identify LNM-positive patients to prevent such overtreatments. Given the emerging interest in exosomal cargo as a source for biomarker development in cancer, we examined the potential of exosomal miRNAs as LNM prediction biomarkers in T1 CRC. We analyzed 200 patients with high-risk T1 CRC from two independent cohorts, including a training (n = 58) and a validation cohort (n = 142). Cell-free and exosomal RNAs from pre-operative serum were extracted, followed by quantitative reverse-transcription polymerase chain reactions for a panel of miRNAs. A panel of four miRNAs (miR-181b, miR-193b, miR-195, and miR-411) exhibited robust ability for detecting LNM in the exosomal vs. cell-free component. We subsequently established a cell-free and exosomal combination signature, successfully validated in two independent clinical cohorts (AUC, 0.84; 95% CI 0.70-0.98). Finally, we developed a risk-stratification model by including key pathological features, which reduced the false positive rates for LNM by 76% without missing any true LNM-positive patients. Our novel exosomal miRNA-based liquid biopsy signature robustly identifies T1 CRC patients at risk of LNM in a preoperative setting. This could be clinically transformative in reducing the significant overtreatment burden of this malignancy.

The Impact of the Pre-operative Neutrophil-lymphocyte Ratio as the Predictive Marker of Post-operative Weight Loss and Improving Diabetes in Sleeve Gastrectomy.,
The Journal of Medical Investigation : JMI, Vol.70, No.1.2, 140-144, 2023.

(要約): The aim was to investigate the impact of the neutrophil-lymphocyte ratio (NLR) in sleeve gastrectomy (SG). 15 obese patients were enrolled in this study ; mean body weight (BW) 127.5kg ; mean body mass index (BMI) 46.7kg/m. 10 of these were diabetics who underwent a SG. The impact of the pre-operative NLR on the percentage of excess weight loss (%EWL) and remission of diabetes 1 year post-operative were examined. The %EWL at 1 year post-operative were 46.3%. Improvements were also evident in the diabetes at 1 year post-operative : complete remission (CR) 40%, partial remission (PR) 20% and Improve 40%. Comparing pre-operative NLR in %EWL<50% and ≧50% in 1 year post-operative, <50% was 2.64 and ≧50% was 2.03. The NLR in CR and PR was significantly lower than that in Improve. The pre-operative NLR may be a predictive marker of weight loss and improving diabetes after SG. J. Med. Invest. 70 : 140-144, February, 2023.

Prognostic impact of frailty after gastrectomy in elderly gastric cancer patients.,
The Journal of Medical Investigation : JMI, Vol.70, No.3.4, 423-429, 2023.

(要約): Frailty plays a crucial role in cancer patients who have received surgery in this recent aging society. We aimed to investigate frailty as a prognostic factor in elderly gastric cancer (GC) patients who underwent curative gastrectomy. We analyzed 86 elderly (over 75 years old) GC patients who underwent curative gastrectomy. Patients were assigned to two groups;frailty group (n=29) and no-frailty group (n=57). Clinicopathological values were compared between the two groups. The OS rate of the frailty group was significantly poorer than that of the no-frailty group (5-yr OS rate;frailty group 52.49% vs. no-frailty group 74.87%, p<0.05). Multivariate analysis of the OS showed that frailty tended to be significant prognostic factor (p=0.09). The DFS rate of the frailty group was significantly poorer than that of the no-frailty group (5-yr DFS rate;frailty group 42.30% vs. no-frailty group 71.55%, p<0.05). Multivariate analysis of the DFS showed that frailty tended to be significant prognostic factor (p=0.14). We identified the clinical impact of frailty prognostic factor for elderly GC patients who underwent gastrectomy. J. Med. Invest. 70 : 423-429, August, 2023.

Role of IDO expression in patients with locally advanced rectal cancer treated with preoperative chemoradiotherapy.,
BMC Cancer, Vol.22, No.1, 1263, 2022.

(要約): The role of the immune system in locally advanced rectal cancer (LARC) following preoperative chemoradiotherapy (CRT) has been widely investigated in recent years. This study examined the prognostic significance of indoleamine-pyrrole 2,3-dioxygenase (IDO) expression in patients with LARC who received preoperative CRT. Ninety patients with LARC who underwent preoperative CRT and curative resection were enrolled. IDO and programmed death-ligand 1 (PD-L1) expression was evaluated by immunohistochemistry. Clinicopathological factors did not significantly differ between patients with positive or negative IDO expression, excluding the correlation of positive IDO expression with better tumor differentiation (p = 0.02). IDO expression was not associated with pathological response (p = 0.44), but it was associated with PD-L1 expression. The 5-year overall survival (OS) rate was significantly worse in the IDO-positive group than in the IDO-negative group (64.8% vs. 85.4%, p = 0.02). Univariate analysis identified IDO and PD-L1 expression (p = 0.02), surgical procedure (p = 0.01), final pathological stage (p = 0.003), lymph node metastasis (p < 0.001), and lymphatic invasion (p = 0.002) as significant prognostic factors for OS. Multivariate analysis revealed that IDO expression (HR: 7.10, p = 0.0006), surgical procedure (HR: 5.03, p = 0.01), lymph node metastasis (HR: 2.37, p = 0.04) and lymphatic invasion (HR: 4.97, p = 0.01) were independent prognostic indicators. Disease-free survival was not correlated with IDO or PD-L1 expression. IDO expression in patients with LARC who received preoperative CRT could be a potential prognostic indicator. IDO expression could be a useful marker for specifying individual treatment strategies in LARC.

Lymph node response to neoadjuvant chemotherapy as an independent prognostic factor in gastric cancer.,
Oncology Letters, Vol.24, No.5, 415, 2022.

(要約): Previous studies have revealed the usefulness of neoadjuvant chemotherapy (NAC) followed by surgery for clinical stage III gastric cancer (GC). The tumor volume at the primary tumor site (PT) is sometimes difficult to measure because of the luminal structure; therefore, evaluation of the lymph node (LN) response to NAC may help to more accurately predict survival outcomes. The present study therefore evaluated the LN response to NAC for prediction of survival outcomes in patients with GC. The study involved 160 patients with clinical stage III GC who underwent NAC (n=14) and upfront surgery (n=146). PT and LN responses to NAC were evaluated, various clinicopathological factors were evaluated and Cox proportional hazard regression analyses were performed to determine survival outcomes. Overall survival (OS) and disease-free survival (DFS) were not significantly different between patients who underwent NAC and those who underwent upfront surgery (OS, P=0.71; DFS, P=0.50). However, although there were no significant differences in PT responses, patients classified as LN non-responders to NAC had a significantly worse prognosis compared with patients classified as LN responders in terms of DFS (PT, P=0.93; LN, P<0.01) and OS (PT, P=0.84; LN, P<0.01). Moreover, a higher neutrophil-lymphocyte ratio tended to be associated with poor DFS [univariate: hazard ratio (HR)=4.23, P=0.06; multivariate: HR=6.45, P=0.04]. Finally, an LN response to NAC was significantly better for prediction of recurrence (univariate, HR=7.79, 95% confidence interval=1.16-63.51, P=0.02; multivariate, HR=7.44, P=0.01). Overall, the current study revealed the clinical importance of the LN response to NAC for predicting survival outcomes in patients with GC. These findings highlight the potential clinical impact of optimizing treatment strategies to improve the selection and management of patients.

Computed tomography texture analysis for the prediction of lateral pelvic lymph node metastasis of rectal cancer.,
World Journal of Surgical Oncology, Vol.20, No.1, 281, 2022.

(要約): This study aimed to investigate the usefulness of computed tomography (CT) texture analysis in the diagnosis of lateral pelvic lymph node (LPLN) metastasis of rectal cancer. This was a retrospective cohort study of 45 patients with rectal cancer who underwent surgery with LPLN dissection at Tokushima University Hospital from January 2017 to December 2021. The texture analysis of the LPLNs was performed on preoperative CT images, and 18 parameters were calculated. The correlation between each parameter and pathological LPLN metastasis was evaluated. The texture parameters were compared between pathologically metastasis-positive LPLNs and metastasis-negative LPLNs. A total of 40 LPLNs were extracted from 25 patients by preoperative CT scans. No LPLNs could be identified in the remaining 19 patients. Eight of the 25 patients had pathologically positive LPLN metastasis. Extracted LPLNs were analyzed by the texture analysis. Pathologically metastasis-positive LPLNs had significantly lower mean Hounsfield unit, gray-level co-occurrence matrix (GLCM) energy, and GLCM Entropy_log2 values, and a significantly larger volume than pathologically metastasis-negative LPLNs. Multivariate analysis revealed that the independent predictive factors for LPLN metastasis were volume (a conventional parameter) (odds ratio 7.81, 95% confidence interval 1.42-43.1, p value 0.018) and GLCM Entropy_log2 (a texture parameter) (odds ratio 12.7, 95% confidence interval 1.28-126.0, p value 0.030). The combination of both parameters improved the diagnostic specificity while maintaining the sensitivity compared with each parameter alone. Combining the CT texture analysis with conventional diagnostic imaging may increase the accuracy of the diagnosis of LPLN metastasis of rectal cancer.

Impact of osteopenia and neutropenia in patients with colorectal cancer treated with FOLFOXIRI: a retrospective cohort study.,
International Journal of Clinical Oncology, Vol.27, No.9, 1439-1449, 2022.

(要約): This study was performed to assess the impact of osteopenia on chemotherapy-induced neutropenia and the prognosis for patients treated with FOLFOXIRI for colorectal cancer. In total, 77 patients who underwent FOLFOXIRI for un-resectable metastatic and advanced colorectal cancer were retrospectively evaluated. Osteopenia was evaluated by the bone mineral density, which was measured using the average pixel density of the trabecular bone in the 11th thoracic vertebra by computed tomography before the introduction of chemotherapy. The relationship between osteopenia and neutropenia was evaluated. Progression-free survival and overall survival of patients with osteopenia and patients with neutropenia were evaluated. Grade ≥ 3 neutropenia was significantly more common in patients with than without osteopenia (p = 0.002). The multivariate analysis showed that osteopenia was a significant independent predictive factor for grade ≥ 3 neutropenia (p = 0.016). There was no significant difference in progression-free survival or overall survival between patients with and without osteopenia. Patients with grade ≥ 3 neutropenia tended to have a higher progression-free survival rate than others (p = 0.059). The overall survival rate was significantly higher in patients with grade ≥ 3 neutropenia than in others (p = 0.011). Osteopenia might be a predictor of chemotherapy-induced neutropenia, and neutropenia might be a prognostic factor for progression-free survival and overall survival in patients with colorectal cancer treated with FOLFOXIRI.

Intraoperative holographic image-guided surgery in a transanal approach for rectal cancer.,
Langenbeck's Archives of Surgery / Deutsche Gesellschaft für Chirurgie, Vol.407, No.6, 2579-2584, 2022.

(要約): Urethral injury is one of the most important complications in transanal total mesorectal excision (TaTME) in male patients with rectal cancer. The purpose of this study was to investigate holographic image-guided surgery in TaTME. Polygon (stereolithography) files were created and exported from SYNAPSE VINCENT, and then uploaded into the Holoeyes MD system (Holoeyes Inc., Tokyo, Japan). After uploading the data, the three-dimensional image was automatically converted into a case-specific hologram. The hologram was then installed into the head mount display, HoloLens (Microsoft Corporation, Redmond, WA). The surgeons and assistants wore the HoloLens when they performed TaTME. In a Wi-Fi-enabled operating room, each surgeon, wearing a HoloLens, shared the same hologram and succeeded in adjusting the hologram by making simple hand gestures from their respective angles. The hologram contributed to better comprehension of the positional relationships between the urethra and the surrounding pelvic organs during surgery. All surgeons were able to properly determine the dissection line. This first experience suggests that intraoperative holograms contributed to reducing the risk of urethral injury and understanding transanal anatomy. Intraoperative holograms have the potential to become a new next-generation surgical support tool for use in spatial awareness and the sharing of information between surgeons.

Preoperative nutrition and exercise intervention in frailty patients with gastric cancer undergoing gastrectomy.,
International Journal of Clinical Oncology, Vol.27, No.9, 1421-1427, 2022.

(要約): The frailty was associated with the worse surgical outcomes and poor prognosis in several cancers. Therefore, we aimed to identify the usefulness of nutrition and exercise intervention (NEI) in frailty patients with GC. We analyzed 58 frailty patients with GC who underwent radical surgery. Among these, 15 patients were performed NEI by nutritional and rehabilitation support team. We compared the surgical outcomes between NEI and non-NEI groups with frailty patients and evaluated the nutrition and rehabilitation markers in pre- and post-NEI groups. The postoperative complication of NEI groups was 6.7% and less than that of non-NEI groups (p = 0.08). The mean postoperative hospital stay of NEI groups was 13.0 ± 1.0 days for NEI groups and significantly shorter than that of non-NEI groups (p = 0.03). The NLR was 4.3 ± 0.6 for pre-NEI and significantly improved by NEI between pre- and post-NEI (p = 0.03). We identified the clinical importance of NEI for improving the surgical outcomes in frailty patients with GC. Our findings highlight the potential clinical impact of optimizing treatment strategies to select and manage the frailty patients.

However, to the best of our knowledge, no studies have explored whether sudachitin can act as an antitumor therapeutic agent by regulating metabolic functions in the tumor microenvironment. In the present study, cell proliferation and cytotoxicity assays were used to determine whether sudachitin inhibited the growth of liver cancer and pancreatic carcinoma, cholangiocarcinoma and colorectal cancer cells and to compare its toxicity against normal fibroblasts and induced cancer-associated fibroblasts (CAFs). Using lactate assays and reverse transcription-quantitative PCR, the effects of sudachitin on glycolysis in CAFs were investigated. The effects of CAFs on malignant tumor cells were evaluated using cell proliferation, wound healing and invasion assays. As result, sudachitin inhibited various types of tumor cells with different half-maximal inhibitory concentrations. Treatment with 50 µM sudachitin for 48 h suppressed tumor and CAFs proliferation but was not cytotoxic against normal fibroblasts. This dose also inhibited glycolysis in CAFs and, thus, diminished their pro-tumorigenic activities. Overall, the present study revealed that sudachitin has promise as a safe and widely available natural antitumor adjuvant.

Vascular variations encountered during laparoscopic surgery for transverse colon, splenic flexure, and descending colon cancer: a retrospective cohort study.,
BMC Surgery, Vol.22, No.1, 170, 2022.

(要約): Laparoscopic surgery for cancer located in the transverse colon or splenic flexure is difficult because of vascular variability in this region and adjacent vital organs such as the pancreas, spleen, and duodenum. This retrospective cohort study involved 51 patients who underwent laparoscopic surgery for colon cancer at Tokushima University Hospital from July 2015 to December 2020. Variations of the middle colic artery (MCA), left colic artery (LCA), middle colic vein (MCV), and first jejunal vein (FJV) and short-term outcomes of laparoscopic surgery in patients with each vascular variation were evaluated. Variations of the MCA, LCA, MCV, and FJV were classified into four, three, five, and three patterns, respectively. The short-term outcomes of laparoscopic surgery for transverse colon cancer in patients with MCA variations and those with FJV variations were evaluated, and no significant difference was found in the operation time, blood loss, postoperative complication rate, time from surgery to start of dietary intake, or time from surgery to discharge among the different variations. Additionally, no significant differences were found in the short-term outcomes of laparoscopic surgery for descending colon cancer in patients with LCA variations. Preoperative assessment of vascular variations may contribute to the stability of short-term outcomes of laparoscopic surgery for transverse colon, splenic flexure, and descending colon cancer.

Blue light irradiation inhibits the growth of colon cancer and activation of cancer-associated fibroblasts.,
Oncology Reports, Vol.47, No.5, 2022.

(要約): Irradiation with a specific wavelength of light using light-emitting diodes (LEDs) has various effects on cells and organisms. Recently, the antitumor effects of visible blue light on tumor cells were reported; however, the mechanism and effects on the tumor microenvironment remain unclear. Human colon cancer cells (HCT-116) were injected into the rectal wall of nude mice. Tumors were irradiated with a 465-nm LED light at 30 mW/cm for 30 min. Tumor volumes and the expression levels of opsin 3 (Opn3), autophagy-related factors, cancer-associated fibroblast (CAF) markers, and programmed cell death 1-ligand (PD-L1) were measured. Additionally, human intestinal fibroblasts were cultured in HCT116-conditioned medium (CM) to prepare CAFs. CAFs were divided into an LED group and a control group, and the effect of the LED light on CAF activation in colon cancer cells was examined. Irradiation with blue LED light suppressed tumor growth; Opn3 expression was localized to the cell membrane in the LED group. Irradiated tumors exhibited increased autophagy-related gene expression. Furthermore, in the LED group, TGF-β and α-SMA expression levels in the fibroblasts were decreased. Regarding CAFs, α-SMA and IL-6 expression levels were decreased in the LED group. HCT-116 cells cultured in CAF-CM with LED irradiation showed no enhanced migration or invasion. In the HCT-116 cells cultured in CM of CAFs irradiated with LED, the relative increase in PD-L1 expression was lower than that noted in the CAF-CM without LED irradiation. Blue LED light may have a direct antitumor effect on colon cancer and also an inhibitory effect on CAFs.

Risk factors for postoperative ileus after diverting loop ileostomy closure.,
BMC Surgery, Vol.22, No.1, 131, 2022.

(要約): Postoperative ileus is one of the most common complications after diverting loop ileostomy closure. Some reports have investigated the risk factors for postoperative complications or ileus after ileostomy closure; however, these studies did not evaluate the index surgery sufficiently. In this study, we evaluated the risk factors, including the details of the index surgery, for ileus after diverting ileostomy closure. This was a retrospective study of patients who underwent ileostomy closure following index surgery for rectal cancer. Patients who developed postoperative ileus [POI (+)] and patients who did not [POI (-)] after ileostomy closure were compared. Sixty-eight patients were evaluated and were divided into two groups: POI (+) (n = 11) and POI (-) (n = 57), and the groups were compared. There were no significant differences in the details of the index surgery, operative procedure, transanal total mesorectal excision, lateral lymph node dissection, operating time, or blood loss. The incidence of Clavien-Dindo grade ≥ III complications and adjuvant chemotherapy after index surgery were significantly higher in the POI (+) group. The incidence of Clavien-Dindo grade ≥ III complications and adjuvant chemotherapy after index surgery may increase the risk of postoperative ileus after ileostomy closure.

The correlation of immunoscore and frailty in colorectal cancer.,
International Journal of Clinical Oncology, Vol.27, No.3, 528-537, 2022.

(要約): The Immunoscore is a useful prognostic and predictive factor for colorectal cancer. Frailty predicts overall and recurrence-free survival following resection of colorectal cancer, and the immunosuppressive state of frailty might affect tumor progression. This study investigated the relationship between the Immunoscore and frailty in colorectal cancer. This retrospective study included patients who underwent radical surgery for stage II and III colorectal cancer (n = 108). Patients were divided into frail (n = 11) and non-frail (n = 97) groups, and low (IS0-2) (n = 70) and high (IS3-4) Immunoscore groups (n = 38), for comparison. American Society of Anesthesiologists physical status was higher, tumor diameter was larger, number of well-differentiated tumors was higher, albumin was lower, 5-year overall survival (OS) was lower (frail group: 50.0%, non-frail group: 90.5%, p < 0.001) and 5-year disease-free survival (DFS) was lower (frail group: 36.4%, non-frail group: 75.2%, p = 0.024) in the frail than in the non-frail group. Left colon cancer was more, 5-year OS was lower (IS0-2 group: 82.0%, IS3-4 group: 96.7%, p = 0.040) and 5-year DFS was lower (IS0-2 group: 66.3%, IS3-4 group: 83.3%, p = 0.043) in the IS0-2 than in the IS3-4 group. The Immunoscore was lower in the frail than in the non-frail group. Immunoscore and frailty are prognostic and predictive factors in colorectal cancer, and they are correlated with each other. The immunosuppressive state from frailty might affect this correlation.

A blood-based noninvasive miRNA signature for predicting survival outcomes in patients with intrahepatic cholangiocarcinoma.,
British Journal of Cancer, Vol.126, No.8, 1196-1204, 2022.

(要約): The prognosis in patients with intrahepatic cholangiocarcinoma (ICC) is generally poor. To improve treatment selection, we sought to identify microRNA (miRNA) signature associated with survival outcomes in ICC. We first analysed the miRNA expression profiles of primary ICC from two public datasets to identify a miRNA panel to detect patients for short-term survival. We then analysed 309 specimens, including 241 FFPE samples from two clinical cohorts (training: n = 177; validation: n = 64) and matched plasma samples (n = 68), and developed a risk-stratification model incorporating the panel and CA 19-9 levels to predict survival outcomes in ICC. We identified a 7-miRNA panel that robustly classified patients with poor outcomes in the discovery cohorts (AUC = 0.80 and 0.88, respectively). We subsequently trained this miRNA panel in a clinical cohort (AUC = 0.83) and evaluated its performance in an independent validation cohort (AUC = 0.82) and plasma samples from the additional validation cohort (AUC = 0.78). Patients in both clinical cohorts who were classified as high-risk had significantly worse prognosis (p < 0.01). The risk-stratification model demonstrated superior performance compared to models (AUC = 0.85). We established a novel miRNA signature that could robustly predict survival outcomes in resected tissues and liquid biopsies to improve the clinical management of patients with ICC.

A transcriptomic signature that predicts cancer recurrence after hepatectomy in patients with colorectal liver metastases.,
European Journal of Cancer, Vol.163, 66-76, 2022.

(要約): Cancer recurrence is an important predictor of survival outcomes in patients with colorectal cancer-associated liver metastasis (CRLM), who undergo radical hepatectomy. Therefore, identification of patients with the greatest risk of recurrence is critical for developing a precision oncology strategy that might include frequent surveillance (in low-risk patients) or a more aggressive treatment approach (in high-risk patients). We performed genome-wide expression profiling, to identify and develop a transcriptomic signature for predicting recurrence in patients with CRLM. We analysed a total of 383 patients with CRLM, including 63 patients from a publicly available data set (the NCBI's Gene Expression Omnibus with accession number GSE81423). and 320 patients from whom surgical specimens were collected for independent training (n = 169) and validation (n = 151) of identified biomarkers. Using Cox's proportional hazard regression analysis, we evaluated the clinical significance of the identified gene signature by comparing its performance with several key clinical factors. We identified a six-gene panel that robustly categorised patients with recurrence in the discovery (area under the curve (AUC) = 0.90). We showed that the panel was a significant predictor of recurrence in the clinical training (AUC = 0.83) and validation cohorts (AUC = 0.81). By combining our panel with key clinical factors, we established a risk-stratification model that emerged as an independent predictor of recurrence (AUC = 0.85; univariate: hazard ratio (HR) = 4.34, 95% confidence interval (CI) = 2.71-6.93, P < 0.001; multivariate: HR = 3.40, 95% CI = 1.76-6.56, P < 0.001). The stratification model revealed recurrence prediction in 89% of high-risk group and non-recurrence in 62% of low-risk group. We established a novel transcriptomic signature that robustly predicts recurrence, which has significant implications for the management of patients with CRLM.

Propensity Score-Matched Analysis of the Short- and Long-Term Outcomes of Robotic Versus Laparoscopic Gastrectomy for Gastric Cancer.,
Annals of Surgical Oncology, Vol.29, No.6, 3887-3895, 2022.

(要約): Robotic gastrectomy (RG) has been rapidly adopted for gastric cancer (GC) treatment. However, the benefits of RG over laparoscopic gastrectomy (LG) for GC remain unclear. A total of 451 patients who underwent either RG (n = 83) or LG (n = 368) for GC were enrolled in this study. A 1:1 matched, propensity score-matched analysis was performed using the following factors: age, sex, body mass index, pT, pN, pStage, tumor location, vessel invasion, tumor markers, surgical procedure, reconstruction method, extent of lymphadenectomy, and Endoscopic Surgical Skill Qualification System qualified surgeon as an operator. The surgical outcomes of the two groups were compared. A well-balanced cohort of 158 patients was analyzed (n = 79 in the RG group, n = 79 in the LG group). Regarding the short-term outcomes, the respective blood loss volume, drain amylase content, and number of retrieved lymph nodes in the RG and LG groups were 38.62 ± 73.06 ml and 67.53 ± 108.20 ml (p < 0.05), 450 ± 371 IU/l and 1590 ± 6392 IU/l (p < 0.01), and 35.02 ± 15.51 and 25.28 ± 11.70 (p < 0.01). The morbidity rate was similar between the RG and LG groups (not significant [NS]). Regarding the long-term survival outcomes, there were no intergroup differences in 3-year overall survival (91.72% in the RG group vs. 83.39% in the LG group: NS) and 3-year, disease-free survival (93.31% in the vs. 90.44%: NS). RG was safe and contributed to better short-term outcomes and similar long-term survival outcomes compared with LG.

Short-term outcomes of laparoscopic / robotic gastrectomy compared with open gastrectomy for advanced gastric cancer following chemotherapy.,
The Journal of Medical Investigation : JMI, Vol.69, No.3.4, 261-265, 2022.

(要約): Purpose : This study aimed to investigate the short-term outcomes of laparoscopic gastrectomy / robotic gastrectomy after chemotherapy in patients with advanced gastric cancer and compare these outcomes with those of open gastrectomy. Methods : Fifty patients who underwent radical gastrectomy for advanced gastric cancer after chemotherapy between 2007 and 2021 were retrospectively analyzed. The patients were divided into two groups : the laparoscopic gastrectomy / robotic gastrectomy (n = 11) and open gastrectomy (n = 39) groups. The short-term outcomes of these procedures were subsequently examined. Results : The laparoscopic gastrectomy / robotic gastrectomy group had significantly shorter hospital stays and lower intraoperative blood loss than the open gastrectomy group. The overall complication rates were 12.8% (5 of 39 patients) and 0% (0 of 11 patients) in the open gastrectomy and laparoscopic gastrectomy / robotic gastrectomy groups, respectively (P = 0.1). Conclusions : Laparoscopic gastrectomy / robotic gastrectomy may be a surgical option after chemotherapy for patients with advanced gastric cancer. J. Med. Invest. 69 : 261-265, August, 2022.

Circulating miRNA Signature Predicts Response to Preoperative Chemoradiotherapy in Locally Advanced Rectal Cancer.,
JCO Precision Oncology, Vol.5, 2021.

(要約): Patients with locally advanced rectal cancer (LARC) are recommended to receive preoperative chemoradiotherapy (PCRT) followed by surgery. Response to PCRT varies widely: 60%-70% of patients with LARC do not derive therapeutic benefit from PCRT, whereas 15%-20% of patients achieve pathologic complete response (pCR). We sought to develop a liquid biopsy assay for identifying response to PCRT in patients with LARC. We analyzed two genome-wide microRNA (miRNA) expression profiling data sets from tumor tissue samples for discovery (GSE68204) and validation (GSE29298). We prioritized biomarkers in pretreatment plasma specimens from clinical training (n = 41; 15 responders and 26 nonresponders) and validation (n = 65; 29 responders and 36 nonresponders) cohorts of patients with LARC. We developed an integrated miRNA panel and established a risk assessment model, which was combined with the miRNA panel and carcinoembryonic antigen levels. Our comprehensive discovery effort identified an 8-miRNA panel that robustly predicted response to PCRT, with an excellent accuracy in the discovery (area under the curve [AUC] = 0.95) and validation (AUC = 0.92) cohorts. We successfully established a circulating miRNA panel with remarkable diagnostic accuracy in the clinical training (AUC = 0.82) and validation (AUC = 0.81) cohorts. Moreover, the predictive accuracy of the panel was significantly superior to conventional clinical factors in both cohorts ( < .01) and the risk assessment model was superior (AUC = 0.83). Finally, we applied our model to detect patients with pathologic complete response and showed that it was dramatically superior to currently used pathologic features (AUC = 0.92). Our novel risk assessment signature for predicting response to PCRT has a potential for clinical translation as a liquid biopsy assay in patients with LARC.

Lymphocyte to C-reactive protein ratio predicts long-term outcomes for patients with lower rectal cancer.,
World Journal of Surgical Oncology, Vol.19, No.1, 201, 2021.

(要約): The lymphocyte to C-reactive protein (CRP) ratio (LCR) is an indicator of systemic inflammation and host-tumor cell interactions. The aim of this study was to investigate the prognostic significance of LCR in lower rectal cancer patients who received preoperative chemo-radiotherapy (CRT). Forty-eight patients with lower rectal cancer who underwent CRT followed by curative surgery were enrolled in this study. Routine blood examinations were performed before and after CRT were used to calculate pre-CRT LCR and post-CRT LCR. The median LCR was used to stratify patients into low and high LCR groups for analysis. The correlation between pre- and post-CRT LCR and clinical outcomes was retrospectively investigated. The pre-CRT LCR was significantly higher than the post-CRT LCR (11,765 and 6780, respectively, P < 0.05). The 5-year overall survival rate was significantly higher for patients with high post-CRT LCR compared with low post-CRT LCR (90.6% and 65.5%, respectively, P < 0.05). In univariate analysis, post-CRT LCR, post-CRT neutrophil to lymphocyte ratio, and fStage were significant prognostic factors for overall survival. In multivariate analysis, post-CRT LCR, but not other clinicopathological factors or prognostic indexes, was a significant prognostic factor for overall survival (P < 0.05). Post-CRT LCR could be a prognostic biomarker for patients with lower rectal cancer.

A Liquid Biopsy Assay for Noninvasive Identification of Lymph Node Metastases in T1 Colorectal Cancer.,
Gastroenterology, Vol.161, No.1, 151-162.e1, 2021.

(要約): We recently reported use of tissue-based transcriptomic biomarkers (microRNA [miRNA] or messenger RNA [mRNA]) for identification of lymph node metastasis (LNM) in patients with invasive submucosal colorectal cancers (T1 CRC). In this study, we translated our tissue-based biomarkers into a blood-based liquid biopsy assay for noninvasive detection of LNM in patients with high-risk T1 CRC. We analyzed 330 specimens from patients with high-risk T1 CRC, which included 188 serum samples from 2 clinical cohorts-a training cohort (N = 46) and a validation cohort (N = 142)-and matched formalin-fixed paraffin-embedded samples (N = 142). We performed quantitative reverse-transcription polymerase chain reaction, followed by logistic regression analysis, to develop an integrated transcriptomic panel and establish a risk-stratification model combined with clinical risk factors. We used comprehensive expression profiling of a training cohort of LNM-positive and LMN-negative serum specimens to identify an optimized transcriptomic panel of 4 miRNAs (miR-181b, miR-193b, miR-195, and miR-411) and 5 mRNAs (AMT, forkhead box A1 [FOXA1], polymeric immunoglobulin receptor [PIGR], matrix metalloproteinase 1 [MMP1], and matrix metalloproteinase 9 [MMP9]), which robustly identified patients with LNM (area under the curve [AUC], 0.86; 95% confidence interval [CI], 0.72-0.94). We validated panel performance in an independent validation cohort (AUC, 0.82; 95% CI, 0.74-0.88). Our risk-stratification model was more accurate than the panel and an independent predictor for identification of LNM (AUC, 0.90; univariate: odds ratio [OR], 37.17; 95% CI, 4.48-308.35; P < .001; multivariate: OR, 17.28; 95% CI, 1.82-164.07; P = .013). The model limited potential overtreatment to only 18% of all patients, which is dramatically superior to pathologic features that are currently used (92%). A novel risk-stratification model for noninvasive identification of T1 CRC has the potential to avoid unnecessary operations for patients classified as high-risk by conventional risk-classification criteria.

A Transcriptomic Signature for Risk-Stratification and Recurrence Prediction in Intrahepatic Cholangiocarcinoma.,
Hepatology, Vol.74, No.3, 1371-1383, 2021.

(要約): Tumor recurrence is frequent even in intrahepatic cholangiocarcinoma (ICC), and improved strategies are needed to identify patients at highest risk for such recurrence. We performed genome-wide expression profile analyses to discover and validate a gene signature associated with recurrence in patients with ICC. For biomarker discovery, we analyzed genome-wide transcriptomic profiling in ICC tumors from two public data sets: The Cancer Genome Atlas (n = 27) and GSE107943 (n = 28). We identified an eight-gene panel (BIRC5 [baculoviral IAP repeat containing 5], CDC20 [cell division cycle 20], CDH2 [cadherin 2], CENPW [centromere protein W], JPH1 [junctophilin 1], MAD2L1 [mitotic arrest deficient 2 like 1], NEIL3 [Nei like DNA glycosylase 3], and POC1A [POC1 centriolar protein A]) that robustly identified patients with recurrence in the discovery (AUC = 0.92) and in silico validation cohorts (AUC = 0.91). We next analyzed 241 specimens from patients with ICC (training cohort, n = 64; validation cohort, n = 177), followed by Cox proportional hazard regression analysis, to develop an integrated transcriptomic panel and establish a risk-stratification model for recurrence in ICC. We subsequently trained this transcriptomic panel in a clinical cohort (AUC = 0.89; 95% confidence interval [CI] = 0.79-0.95), followed by evaluating its performance in an independent validation cohort (AUC = 0.86; 95% CI = 0.80-0.90). By combining our transcriptomic panel with various clinicopathologic features, we established a risk-stratification model that was significantly superior for the identification of recurrence (AUC = 0.89; univariate HR = 6.08, 95% CI = 3.55-10.41, P < 0.01; and multivariate HR = 3.49, 95% CI = 1.81-6.71, P < 0.01). The risk-stratification model identified potential recurrence in 85% of high-risk patients and nonrecurrence in 76% of low-risk patients, which is dramatically superior to currently used pathological features. We report a transcriptomic signature for risk-stratification and recurrence prediction that is superior to currently used clinicopathological features in patients with ICC.

The inhibitory effect of TU-100 on hepatic stellate cell activation in the tumor microenvironment.,
Oncotarget, Vol.11, No.49, 4593-4604, 2020.

(要約): The tumor microenvironment is involved in acquiring tumor malignancies of colorectal liver metastasis (CRLM). We have reported that TU-100 (Daikenchuto) suppresses hepatic stellate cell (HSC) activation in obstructive jaundice. In this study, we report new findings as the direct and indirect inhibitory effects of TU-100 on cancer cell growth through the suppression of HSC activation. The HSCs (LX2) were cultured in colon cancer cells (HCT116 and HT29)-conditioned medium (CM) with or without TU-100 treatment (90, 270, 900 g/ml). Activated HSCs (aHSCs) were detected by -SMA and IL-6 mRNA expressions and cytokine arrays of HSC's culture supernatants. Cancer cell growth was analyzed for proliferation and migration ability, compared with TU-100 treatment. To investigate the direct anti-tumor effect of TU-100, cancer cells were cultured in the presence of aHSC-CM and TU-100 (90, 270, 900) or aHSC-CM alone, and assessed autophagosomes, conversion to LC3-II protein, and Beclin-1 mRNA expression. Colon cancer-CM significantly increased -SMA and IL-6 mRNA expressions of aHSC. -SMA and IL-6 mRNA expressions of aHSC, and IL-6 secretions from aHSCs were significantly decreased with TU-100 (270, 900) treatment, compared to colon cancer-CM alone. Compared with normal culture medium, aHSC-CM led to a significantly increased cell number and modified HSC-CM (TU-100; 270, 900) significantly suppressed cancer cell growth and migration. TU-100 (900) treatment induced autophagy and significantly promoted the autophagic cell death. TU-100 inhibited colon cancer cell malignant potential by both suppressing HSC activation and inducing directly autophagy of cancer cells.

Adipose Tissue From Type 1 Diabetes Mellitus Patients Can Be Used to Generate Insulin-Producing Cells.,
Pancreas, Vol.49, No.9, 1225-1231, 2020.

(要約): We aimed to determine whether responsive insulin-producing cells (IPCs) could be generated from adipose-derived stem cells (ADSCs) isolated from patients with type 1 diabetes mellitus (T1DM). We isolated ADSCs from adipose tissue of 4 patients (one patient with T1DM and 3 nondiabetic patients), who underwent surgery and differentiated them into IPCs with using a 2-step xeno-antigen free, 3-dimensional culture method. Characteristics of isolated ADSCs, in vitro cell quality, programmed cell death ligand-1 (PDL-1) expression, and transplantation into streptozotocin induced diabetic nude mice were investigated. Adipose-derived stem cells from T1DM patients and commercially obtained ADSCs showed the same surface markers; CD31CD34CD45CD90CD105CD146. Moreover, the generated IPCs at day 21 demonstrated appropriate autonomous insulin secretion (stimulation index, 3.5; standard deviation, 0.8). Nonfasting blood glucose concentrations of IPC-transplanted mice were normal at 30 days. The normalized rate of IPC-transplanted mice was significantly higher than that of the sham-operated group (P < 0.05). Insulin-producing cells generated from T1DM adipose tissue expressed high levels of PDL-1. Insulin-producing cells obtained from adipose tissue of T1DM patients are capable of secreting insulin long-term and achieve normoglycemia after transplantation. Expression of PDL-1 suggests the potential for immune circumvention.

HIF-1 expression in liver metastasis but not primary colorectal cancer is associated with prognosis of patients with colorectal liver metastasis.,
World Journal of Surgical Oncology, Vol.18, No.1, 241, 2020.

(要約): The role of hypoxia-inducible factor-1 (HIF-1 ) in primary colorectal cancer (CRC) and colorectal liver metastasis (CRLM) has remained unclear. The aim of this study was to investigate HIF-1 expression and its association with prognosis in patients with CRLM with a focus on hepatic stellate cells (HSCs). Colon cancer cells were cultured in HSC-conditioned medium (CM), and HIF-1 expression and cell migration were analyzed. Seventy-five patients with CRLM who underwent an initial curative hepatectomy were enrolled. We examined HIF-1 expressions and patient prognosis between primary CRCs and the matched liver metastatic specimens. Activated HSCs induced HIF-1 mRNA and protein expression in colon cancer cells (p < 0.01) and promoted cell migration (p < 0.01). The positive rates of HIF-1 expression in primary CRCs and liver metastases were 68.0 and 72.0%, respectively. There were no differences in overall (OS) and disease-free survival (DFS) of HIF-1 expression in primary CRC. However, HIF-1 expression in liver metastasis correlated to poor prognosis in both OS and DFS. Furthermore, patients with HIF-1 positive expression in liver metastasis had poor prognosis. HIF-1 expression in liver metastasis determines poor prognosis of CRLM patients. HSCs might play a key role in aggressive phenotypes of tumor cells.

Usefulness of virtual three-dimensional image analysis in inguinal hernia as an educational tool.,
Surgical Endoscopy, Vol.34, No.2, 1923-1928, 2020.

(要約): The pre-operative three-dimensional (3D) imaging technique has resulted in a better surgical outcome for patients and has been used as an education and diagnostic tool. However, there are no reports concerning the usefulness of the 3D imaging technique in laparoscopic transabdominal pre-peritoneal repair (TAPP) so the aim of this study was to investigate the usefulness of the 3D imaging technique in laparoscopic TAPP as an educational tool for medical students. Six (6) patients who underwent laparoscopic TAPP for inguinal hernia were enrolled in this study. 3D reconstruction was performed from pre-operative computed tomography (CT) and the usefulness of pre-operative 3D simulation compared with intra-operative laparoscopic imaging was validated. Moreover, thirty (30) medical students at the university completed a multiple-choice questionnaire (MCQ) to determine the level of their satisfaction and understanding of anatomy resulting from the study. The local anatomy of the patients was identified as the same during the operation as the pre-operative 3D simulation. The results of the MCQ showed that most of the medical students were extremely (23%) or very (67%) satisfied with the effect of pre-operative 3D simulation on the quality of the surgery. Moreover, most students could understand the surgery anatomy by the 3D simulation extremely well (40%) or very well (47%) and agreed on the usefulness of this procedure for learning anatomy. Pre-operative 3D simulation increases the understanding of detailed anatomy and virtual three-dimensional image analysis in laparoscopic TAPP is useful as an educational tool for medical students.

Carbohydrate Antigen 19-9 Is a Prognostic Factor Which Correlates With HDAC1 and HIF-1 for Intrahepatic Cholangiocarcinoma.,
Anticancer Research, Vol.39, No.11, 6025-6033, 2019.

(要約): Carbohydrate antigen 19-9 (CA19-9) is a poor prognostic marker in intrahepatic cholangiocarcinoma (IHCC). Previous studies have shown a link between hypoxia and CA19-9 in cancer, and we have previously demonstrated a correlation between HDAC1 and HIF-1 in IHCC. Here, we evaluated the expression and correlation of CA19-9 with HIF-1 and HDAC in IHCC. This study included 62 patients with IHCC who underwent primary hepatectomy at our department. Clinicopathological characteristics were examined. Immunohistochemical expression of HIF-1 and HDAC1 in specimens was quantitatively evaluated. Patients with high preoperative serum CA19-9 levels showed clinicopathological characteristics associated with tumour progression. High CA19-9 levels were associated with worse overall and recurrence-free survival. Univariate and multivariate analysis detected high CA19-9 levels as an independent poor prognostic factor for IHCC. Serum CA19-9 was significantly correlated with both HIF-1 and HDAC1 expression. High serum CA19-9 level is a poor prognostic factor for overall survival in IHCC and correlates with HIF-1 and HDAC1 expression.

The Differences in the Characteristics of Insulin-producing Cells Using Human Adipose-tissue Derived Mesenchymal Stem Cells from Subcutaneous and Visceral Tissues.,
Scientific Reports, Vol.9, No.1, 13204, 2019.

(要約): The aim of this study was to investigate the characteristics of insulin producing cells (IPCs) differentiated from adipose-tissue derived stem cells (ADSCs) isolated from human subcutaneous and visceral adipose tissues and identify ADSCs suitable for differentiation into efficient and functional IPCs. Subcutaneous and visceral adipose tissues collected from four (4) patients who underwent digestive surgeries at The Tokushima University (000035546) were included in this study. The insulin secretion of the generated IPCs was investigated using surface markers by: fluorescence activated cell sorting (FACS) analysis; cytokine release; proliferation ability of ADSCs; in vitro (glucose-stimulated insulin secretion: (GSIS) test/in vivo (transplantation into streptozotocin-induced diabetic nude mice). The less fat-related inflammatory cytokines secretions were observed (P < 0.05), and the proliferation ability was higher in the subcutaneous ADSCs (P < 0.05). Insulin expression and GISI were higher in the subcutaneous IPCs (P < 0.01 and P < 0.05, respectively). The hyperglycaemic state of all mice that received IPCs from subcutaneous fat tissue converted into normo-glycaemia in thirty (30) days post-transplantation (4/4,100%). Transplanted IPCs were stained using anti-insulin and anti-human leukocyte antigen antibodies. The IPCs generated from the ADSCs freshly isolated from the human fat tissue had sufficient insulin secreting ability in vitro and in vivo.

A case of gastric heterotopic pancreas with gastroduodenal invagination.,
Surgical Case Reports, Vol.5, No.1, 110, 2019.

(要約): Heterotopic pancreas (HP) is a rare disease commonly found incidentally on imaging studies, at endoscopy or at autopsy and can be associated with abdominal pain, vomiting, heart burn, gastric outlet obstruction, and even dysphagia in very rare cases. Heinrich's classified HP into three groups, types1-3, with Heinrich's type 3 HP the rarest and difficult to diagnose properly because it has only pancreatic ducts but has no islet and acini. The aim of this study is to report a case of gastric outlet obstruction caused by type 3 HP with gastroduodenal invagination with reference to the literature and diagnosed finally by immuno-histochemical analysis. The case presented is a 40-year-old male presenting with vomiting and abdominal pain. Computed tomography (CT) revealed a cystic mass in the upper abdomen and he was referred to the Tokushima University. Gastric fiber showed that the pedunculated mass originated from the stomach. An open distal gastrectomy was performed. Pathologically, there was small glands proliferation in the sub-mucosal (SM) layer which was membrane and cytoplasm (MUC)1 positive and muscle proliferation. This finding revealed the tumor as HP. Postoperative course was uneventful and the patient was discharged 12 days after surgery. The patient has remained well 12 months after surgery. HP should be considered in the differential diagnosis of SM tumors with gastroduodenal invagination even if this is a rare symptom.

The protective effect of epigallocatechin 3-gallate on mouse pancreatic islets via the Nrf2 pathway.,
Surgery Today, Vol.49, No.6, 536-545, 2019.

(要約): Epigallocatechin 3-gallate (EGCG), a green tea polyphenol, has been shown to have anti-oxidant and anti-inflammatory effects in vitro and in vivo. The aim of this study was to investigate the effects and mechanism of EGCG on isolated pancreatic islets as pre-conditioning for pancreatic islet transplantation. The pancreatic islets were divided into two groups: an islet culture medium group (control) and an islet culture medium with EGCG (100 M) group. We investigated the islet viability, Nrf2 expression, reactive oxygen species (ROS) production, and heme oxygenase-1 (HO-1) mRNA. Five hundred islet equivalents after 12 h of culture for the EGCG 100 M and control group were transplanted under the kidney capsule of streptozotocin-induced diabetic ICR mice. The cell viability and insulin secretion ability in the EGCG group were preserved, and the nuclear translocation of Nrf2 was increased in the EGCG group (p < 0.01). While the HO-1 mRNA levels were also higher in the EGCG group than in the control group (p < 0.05), the ROS production was lower (p < 0.01). An in vivo functional assessment showed that the blood glucose level had decreased in the EGCG group after transplantation (p < 0.01). EGCG protects the viability and function of islets by suppressing ROS production via the Nrf2 pathway.
