Gastric fundic gland polyposis and cancer development after eradication of Helicobacter pylori in patient with gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS).,
Gastric Cancer, Vol.27, No.3, 635-640, 2024.

(要約): A 44-year-old woman with gastric cancer (GC) and fundic gland polyposis (FGPs) was referred to our hospital for further diagnosis and treatment. She successfully underwent eradication therapy for Helicobacter pylori (HP) 6 years ago, but did not exhibit FGPs at that time. When she underwent an esophagogastroduodenoscopy 2, 4, and 5 years after the eradication of HP, her imaging results revealed the existence of FGPs which gradually increased in her gastric fundus and body. Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) was suspected and a mutational analysis was performed, revealing an APC promoter 1B variant c.-191T > C. A robotic total gastrectomy with lymphadenectomy was performed. Histopathological analysis of the surgical specimens revealed GC with no lymph node metastasis. GAPPS is characterized by GC and FGPs. However, our case shows different gastric phenotypes that are dependent on the status of HP infection.

Efficacy of immune checkpoint inhibitors in patients with anorectal melanoma in association with immune-related adverse events: a case series.,
Clinical Journal of Gastroenterology, Vol.Online ahead of print., 2023.

(要約): Anorectal melanoma (AM) is a rare subtype of mucosal melanoma with a poor prognosis. Given its rarity compared to its cutaneous counterpart, the benefits and side effects of immune checkpoint inhibitor (ICI) therapy and the relationship between side effects and prognosis remain unclear. Herein, we describe the clinical presentation of five patients with AM treated with ICI as well as their relationship to the treatment course and the development of immune-related adverse events (irAEs). Three patients received sequential or concurrent administrations of nivolumab and ipilimumab, one received nivolumab alone, and one received ipilimumab alone. The response rate (RR) and disease control rate (DCR) were 40% and 80%, respectively. Pituitary and hepatic dysfunctions were the most common irAEs observed (40% each), followed by thyroid, diarrhea, and renal dysfunctions (20% each). The RR was 67% in patients with irAEs while no response was observed in patients without irAEs. DCR was 100% and 50% in patients with and without irAEs, respectively. Overall survival was 34 months in irAE and 8.75 months in non-irAE cases, with a longer survival trend in irAE cases. ICI therapy was effective and well-tolerated by AM patients, with potentially better outcomes for those who experienced irAEs compared to those who did not.

Clinical Outcomes of Comprehensive Genomic Profiling Tests for Gastrointestinal Cancers: Experience from Tokushima University Hospital.,
The Journal of Medical Investigation : JMI, Vol.70, No.1.2, 154-159, 2023.

(要約): In Japan, cancer genome profiling (CGP) for cancer patients without standard treatment has been covered by public insurance since June 2019. This study analyzed data of 122 patients with gastrointestinal tumors who underwent CGP to clarify cancer genome medicine's current status and possible problems at the Tokushima University Hospital. The major types of cancer included pancreatic (n=30), colorectal (n=25), biliary tract (n=15), gastric (n=11), and hepatocellular carcinoma (n=8). CGP tests included F1CDx in 70 patients (57%), F1LCDx in 36 (30%), TSO500 in 14 (11%), and NCC Oncopanel in 2 (2%). Actionable gene alterations were identified in 72 patients (59%), but only 5 patients (4%) were treated for pancreatic (n=1), colorectal (n=3), and small bowel cancers (n=1). The main reasons for not receiving genotype-matched therapy included the lack of appropriate drugs or clinical trials that matched the actionable gene alterations (n=40) and the inability to participate in clinical trials (n=10). There is still not a sufficient number of patients receiving genotype-matched treatment for gastrointestinal cancers. To promote cancer genome medicine in regional areas, attempts to improve access to genotype-matched therapies are required, as well as to promote the development of new molecular-targeted drugs and clinical trials for these drugs.

Two cases of anal squamous cell carcinoma achieving complete response after docetaxel + cisplatin + S1 (DCS) induction chemotherapy followed by chemoradiation.,
Clinical Journal of Gastroenterology, Vol.16, No.2, 180-186, 2022.

(要約): Anal squamous cell carcinoma (ASCC) is an uncommon tumor. However, its incidence is increasing worldwide. Surgical resection of locally advanced cases requires permanent anal prosthesis. Thus, chemoradiotherapy (CRT) is preferred as the first-line treatment; however, high local recurrence rate remains an issue. Here, we describe two cases of locally advanced ASCC treated with docetaxel + cisplatin + S-1 (DCS) followed by CRT with S-1 that showed complete response. The two patients, aged 69 and 65 years, were diagnosed with ASCC (cStage IIIB) at our hospital. Due to extensive lymph node metastases, the patients were treated with triple induction chemotherapy (DCS) followed by CRT with S-1. Positron emission tomography/computed tomography performed six months after starting the treatment showed disappearance of tumors, indicating a complete response. The patients continued to receive S-1 for one year and achieved relapse-free long-term survival since the completion of treatment. Therefore, induction chemotherapy with DCS, prior to CRT with S-1 may benefit patients with locally advanced ASCC.

がん遺伝子パネル検査を契機にHER2陽性が判明しTrastuzumab投与により長期生存が得られた進行胃癌の1例.,
日本消化器病学会雑誌, Vol.119, No.10, 937-945, 2022年.

(要約): Intratumoral HER2 heterogeneity is a well-described gastric cancer feature and may explain many false-negative results related to this oncogene. An 81-year-old man was diagnosed at our hospital with stage IV gastric cancer with multiple lymph node metastases. Immunohistochemistry (IHC) analysis indicated that the primary tumor was HER2-negative. After a chemotherapy course, we submitted a pretreatment biopsy specimen for comprehensive cancer genome profiling (CGP) to determine the last-line therapy. This revealed HER2 amplification. The specimen was reevaluated using fluorescence in situ hybridization and IHC with deeper-cut specimens, which confirmed that the tumor was indeed HER2-positive. Therefore, the patient was treated with chemotherapy plus trastuzumab, which elicited tumor shrinkage and conferred long-term survival. Our current data underscore the CGP importance, which can provide more accurate tumor profilings and inform subsequent treatment decisions.

Colorectal carcinoma occurring via the adenoma-carcinoma pathway in patients with serrated polyposis syndrome.,
Journal of Gastroenterology, Vol.57, No.4, 286-299, 2022.

(要約): Although serrated polyposis syndrome (SPS) is associated with an increased colorectal cancer (CRC) risk, the carcinogenic mechanisms remain unknown. We investigated clinicopathological characteristics and genetic abnormalities in colorectal polyps and CRC to elucidate carcinogenic mechanisms in SPS. We retrospectively analyzed clinicopathological features of colorectal polyps in 44 SPS patients, and examined mutations of genes including APC, RAS, BRAF, and TP53, and microsatellite instability (MSI) in CRC tissues. Of the 44 patients, 25 (56%) fulfilled WHO criterion 1, 11 (25%) fulfilled criterion 2, and 8 (18%) fulfilled both. A total of 956 polyps were observed; 642 (67%) hyperplastic polyps (HP), 204 (21%) sessile serrated lesions (SSL), 10 (1%) traditional serrated adenoma (TSA), and 100 (11%) adenomas. The median numbers of polyps (/patient) were 10.5 (IQR 2.75-23) HPs, 4.0 (2.0-6.0) SSLs, 0 (0-0) TSA, and 1 (0-3.3) adenoma. SSL and HP located preferentially in the proximal and distal colon, respectively. Twenty-two CRCs were found in 18 patients. Based on the histological coexistence of SSL/TSA, BRAF mutation and MSI, 5 CRCs (26%) were classified as serrated-neoplasia pathway. Conversely, based on the coexistence of adenoma, APC/RAS and TP53 mutations, 11 CRCs (58%) were classified as adenoma-carcinoma pathway. The remaining three were unclassifiable. Most CRCs through adenoma-carcinoma pathway were located in the left-side colorectum and patients bearing those met criterion 2, characterized by many HP and advanced adenomas. Adenoma was a significant risk factor for CRC. Our results suggest that more than half of the CRCs, particularly those in the left-side colorectum, developed through the adenoma-carcinoma pathway in SPS patients. Adenoma was a risk factor for CRCs, suggesting its importance in colorectal carcinogenesis.

S100P expression via DNA hypomethylation promotes cell growth in the sessile serrated adenoma/polyp-cancer sequence.,
Digestion, Vol.102, No.5, 789-802, 2021.

(要約): Sessile serrated adenomas/polyps (SSA/Ps) are a putative precursor lesion of colon cancer. Although the relevance of DNA hypermethylation in the SSA/P-cancer sequence is well documented, the role of DNA hypomethylation is unknown. We investigated the biological relevance of DNA hypomethylation in the SSA/P-cancer sequence by using 3-dimensional organoids of SSA/P. We first analyzed hypomethylated genes using datasets from our previous DNA methylation array analysis on 7 SSA/P and 2 cancer in SSA/P specimens. Expression levels of hypomethylated genes in SSA/P specimens were determined by RT-PCR and immunohistochemistry. We established 3-dimensional SSA/P organoids and performed knockdown experiments using a lentiviral shRNA vector. DNA hypomethylation at CpG sites of the gene was quantitated by MassARRAY analysis. The mean number of hypomethylated genes in SSA/P and cancer in SSA/P was 41.6 ± 27.5 and 214 ± 19.8, respectively, showing a stepwise increment in hypomethylation during the SSA/P-cancer sequence. S100P, S100α2, PKP3, and MUC2 were most commonly hypomethylated in SSA/P specimens. The mRNA and protein expression levels of S100P, S100α2, and MUC2 were significantly elevated in SSA/P compared with normal colon tissues, as revealed by RT-PCR and immunohistochemistry, respectively. Among these, mRNA and protein levels were highest for S100P. Knockdown of the S100P gene using a lentiviral shRNA vector in 3-dimensional SSA/P organoids inhibited cell growth by >50% (p < 0.01). The mean diameter of SSA/P organoids with S100P gene knockdown was significantly smaller compared with control organoids. MassARRAY analysis of DNA hypomethylation in the S100P gene revealed significant hypomethylation at specific CpG sites in intron 1, exon 1, and the 5'-flanking promoter region. These results suggest that DNA hypomethylation, including S100P hypomethylation, is supposedly associated with the SSA/P-cancer sequence. S100P overexpression via DNA hypomethylation plays an important role in promoting cell growth in the SSA/P-cancer sequence.

胃癌における免疫チェックポイント阻害薬の効果と免疫関連副作用(irAE) との関連性についての検討,
四国医学雑誌, Vol.76, No.3-4, 173-178, 2020年.

(要約): Recently, immune checkpoint inhibitors(ICI)have been approved for use in advanced gastric cancer(AGC)based on the positive results of ATTRACTION‐2 trial in Japan. There has been accumulating evidence that the development of immune-related adverse events(irAE)may be associated with a response to ICI therapy, particularly in lung cancer, although little is known about these correlations in gastrointestinal cancer. To investigate the efficacy and irAE of ICI treatment and their correlation in AGC, we retrospectively examined 29 patients with AGC who received nivolumab therapy in our departments. Among them, 15 patients(52%)developed irAEs including 4 patients(14%)for grade 3 irAEs ; liver dysfunction(n＝2), type 1 diabetes mellitus(n＝2) and adrenal insufficiency(n＝1). The median overall survival was12．0months in the irAE group and 3．25 months in the non-irAE group(p＝0．164), which suggested the relationship between the effects and irAEs in ICI treatment of AGC. Further research is required to understand the implications of irAE characteristics on ICI response in GCA patients.

Synergistic anti-tumor activity of miriplatin and radiation through PUMA-mediated apoptosis in hepatocellular carcinoma.,
Journal of Gastroenterology, Vol.55, No.11, 1072-1086, 2020.

(要約): The prognosis for patients with unresectable advanced hepatocellular carcinoma (HCC) is poor. Miriplatin is a hydrophobic platinum compound that has a long retention time in lesions after transarterial chemoembolization (TACE). We investigated anti-tumor activity of miriplatin combined with irradiation on HCC cells, and its underlying mechanism of apoptosis. We also analyzed the effectiveness of miriplatin-TACE and radiotherapy for locally advanced HCC. Human HCC cell lines HepG2 and HuH-7 were treated with DPC (active form of miriplatin) and radiation, and synergy was evaluated using a combination index (CI). Apoptosis-related proteins and cell cycles were analyzed by western blotting and flowcytometry. We retrospectively analyzed treatment outcomes in 10 unresectable HCC patients with vascular/bile duct invasion treated with miriplatin-TACE and radiotherapy. DPC or X-ray irradiation decreased cell viability dose-dependently. DPC plus irradiation decreased cell viability synergistically in both cell lines (CI < 1, respectively). Cleaved PARP expression was induced much more strongly by DPC plus irradiation than by each treatment alone. Expression of p53 up-regulated modulator of apoptosis (PUMA) was significantly induced by the combination, and knockdown of PUMA with siRNA significantly decreased apoptosis in both cell lines. DPC plus irradiation caused sub-G1, G2/M, and S phase cell arrest in those cells. The combination of miriplatin-TACE and radiotherapy showed a high response rate for patients with locally advanced HCC despite small number of patients. Miriplatin plus irradiation had synergistic anti-tumor activity on HCC cells through PUMA-mediated apoptosis and cell cycle arrest. This combination may possibly be effective in treating locally advanced HCC.

Potential use of lenvatinib for patients with unresectable hepatocellular carcinoma including after treatment with sorafenib: Real-world evidence and in vitro assessment via protein phosphorylation array.,
Oncotarget, Vol.11, No.26, 2531-2542, 2020.

(要約): The efficacy and safety of lenvatinib (LEN) as a second/third-line treatment for unresectable hepatocellular carcinoma (HCC) after sorafenib (SOR) therapy remains unknown. We evaluated the outcomes of second/third-line LEN treatment, investigated the sensitivity of a SOR-resistant HCC cell line (PLC/PRF5-R2) to LEN, and assessed their signal transduction pathways by protein array analysis. We retrospectively enrolled 57 patients with unresectable HCC. Fifty-three radiologically evaluated patients comprised 34 molecular-targeted agent (MTA)-naive (first-line), nine intolerant to SOR (second-line), and 10 resistant to regorafenib (third-line). The objective response rates (ORRs) were 61.8% in first-line, 33.3% in second-line, and 20.0% in third-line groups. The overall survival (OS) in the first-line was significantly longer than that in the third-line group ( < 0.05). Patients with better liver functional reserves (child score, ALBI grade) exhibited higher ORR and longer OS. The IC of LEN against PLC/PRF5-R2 was significantly higher than that against PLC/PRF5. LEN significantly inhibited more LEN-related signal transduction pathways in PLC/PRF5 than in PLC/PRF5-R2 cells. This suggests that LEN is active and safe as a second/third-line treatment for unresectable HCC. LEN seems more effective for patients with HCC with better hepatic reserve functions or before MTA-resistance is acquired because of the partial cross-resistance to SOR.

JMJD2A sensitizes gastric cancer to chemotherapy by cooperating with CCDC8.,
Gastric Cancer, Vol.23, No.3, 426-436, 2020.

(要約): Jumonji domain-containing protein 2A (JMJD2A) of the JMJD2 family of histone lysine demethylases has been implicated in tumorigenesis. However, its expression and role in gastric cancer (GC) drug resistance remain unknown. Here, we investigated the role of JMJD2A in GC chemotherapeutic susceptibility and its clinical relevance in GC. We selected 12 relevant genes from previously identified gene signatures that can predict GC susceptibility to docetaxel, cisplatin, and S-1 (DCS) therapy. Each gene was knocked down using siRNA in GC cell lines, and cell viability assays were performed. JMJD2A expression in GC cell lines and tissues was assessed using qRT-PCR and immunohistochemistry, respectively. A JMJD2A downstream target related to drug susceptibility was examined using whole-gene expression array and immunoprecipitation. Among the 12 candidate genes, down-regulation of JMJD2A showed the maximum effect on GC susceptibility to anti-cancer drugs and increased the IC values for 5-FU, cisplatin, and docetaxel 15.3-, 2.7-, and 4.0-fold, respectively. JMJD2A was universally expressed in 12 GC cell lines, and its overexpression in GC tissue was positively correlated with tumor regression in 34 DCS-treated patients. A whole-gene expression array of JMJD2A-knockdown GC cells demonstrated a significant decrease in the expression of pro-apoptotic coiled-coil domain containing 8 (CCDC8), a downstream target of JMJD2A. Direct interaction between CCDC8 and JMJD2A was verified using immunoprecipitation. CCDC8 inhibition restored drug resistance to docetaxel, cisplatin, and S-1. Our results indicate that JMJD2A is a novel epigenetic factor affecting GC chemotherapeutic susceptibility, and JMJD2A/CCDC8 is a potential GC therapeutic target.

First report of an Asian family with gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) revealed with the germline mutation of the APC exon 1B promoter region.,
Gastric Cancer, Vol.21, No.6, 1058-1063, 2018.

(要約): A 48-year-old Japanese female with left hypochondralgia presented at our hospital. Esophagogastroduodenoscopy (EGD) revealed gastric cancers and carpeting fundic gland polyposis (FGPs) without Helicobacter pylori infection. Computed tomography showed multiple liver metastases. Total colonoscopy revealed a colonic tubular adenoma but not polyposis. She was diagnosed as having advanced gastric cancer with liver metastasis and received chemotherapy. Her mother had died from gastric cancer, and her elderly brother and niece had FGPs as revealed by EGD. Thus, the pedigree was diagnosed as gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS). Germline mutation analysis exhibited a point mutation in exon1B of the APC gene (c.-191T > C). Adenocarcinoma showed a gastric mucinous phenotype and was positive for a somatic mutation of p53, suggesting that p53 mutation may play a role in FGPs carcinogenesis. This is the first family with GAPPS in Asia in whom germline mutation of APC exon 1B has been detected.

Linked color imaging enhances endoscopic detection of sessile serrated adenoma/polyps.,
Endoscopy International Open, Vol.6, No.3, E322-E334, 2017.

(要約): Although new image-enhanced endoscopy (IEE) technologies such as blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) have been developed, their utility for the detection of sessile serrated adenoma/polyps (SSA/Ps) is still unclear. This study aimed to evaluate the utility of BLI, BLI-bright, and LCI for SSA/P detection in still image examinations and in a prospective randomized controlled trial (RCT). A group of 6 expert and non-expert endoscopists read 200 endoscopic still images containing SSA/P lesions using white light image (WLI), BLI, BLI-bright, and LCI. Color differences were calculated using the color space method. A prospective RCT of tandem colonoscopy with WLI and LCI was performed. Patients with SSA/P and those with a history of SSA/P that had been endoscopically removed were enrolled and randomly allocated to WLI-LCI or LCI-WLI groups. Additional endoscopic detection rates for SSA/P were compared between the 2 groups. LCI showed the highest SSA/P detection rate among the 4 modes for both expert and non-expert endoscopists. The detection rate with LCI for the 6 expert endoscopists (mean 98.3 ± standard deviation 2.0 %) was significantly higher than that with WLI (86.7 ± 6.0 %, < 0.01). Likewise, the detection rate with LCI for the 6 non-expert endoscopists (92.3 ± 2.9 %) was significantly higher than that with WLI (72.7 ± 11.5 %, < 0.01). The color difference of SSA/P with LCI was the highest among the 4 modes, and was significantly higher than with WLI (median 15.9, (interquartile range 13.7 - 20.6) vs. 10.2, (7.6 - 14.2); < 0.0001). In the RCT, a total of 44 patients (WLI-LCI 22 vs. LCI-WLI 22) underwent colonoscopy. The additional detection rate for SSA/P in the second inspection in the WLI-LCI group (21.6 %, 8/37) was significantly higher than in the LCI-WLI group (3.2 %, 1/31; = 0.02). The small, flat, non-mucus and isochromatic SSA/Ps in the transverse colon were detected more frequently in the second inspection with LCI. LCI was the most sensitive mode for SSA/P detection among WLI, BLI, BLI-bright, and LCI in the still image examinations. Our RCT strongly suggests that LCI is superior to conventional WLI for SSA/P detection during colonoscopy. UMIN000017599.

Molecular imaging of aberrant crypt foci in the human colon targeting glutathione S-transferase P1-1.,
Scientific Reports, Vol.7, No.1, 6536, 2017.

(要約): Aberrant crypt foci (ACF), the earliest precursor lesion of colorectal cancers (CRCs), are a good surrogate marker for CRC risk stratification and chemoprevention. However, the conventional ACF detection method with dye-spraying by magnifying colonoscopy is labor- and skill-intensive. We sought to identify rat and human ACF using a fluorescent imaging technique that targets a molecule specific for ACF. We found that glutathione S-transferase (GST) P1-1 was overexpressed in ACF tissues in a screening experiment. We then synthesized the fluorogenic probe, DNAT-Me, which is fluorescently quenched but is activated by GSTP1-1. A CRC cell line incubated with DNAT-Me showed strong fluorescence in the cytosol. Fluorescence intensities correlated significantly with GST activities in cancer cell lines. When we sprayed DNAT-Me onto colorectal mucosa excised from azoxymethane-treated rats and surgically resected from CRC patients, ACF with strong fluorescent signals were clearly observed. The ACF number determined by postoperative DNAT-Me imaging was almost identical to that determined by preoperative methylene blue staining. The signal-to-noise ratio for ACF in DNAT-Me images was significantly higher than that in methylene blue staining. Thus, we sensitively visualized ACF on rat and human colorectal mucosa by using a GST-activated fluorogenic probe without dye-spraying and magnifying colonoscopy.

Response Predictors of S-1, Cisplatin, and Docetaxel Combination Chemotherapy for Metastatic Gastric Cancer: Microarray Analysis of Whole Human Genes.,
Oncology, Vol.93, No.2, 127-135, 2017.

(要約): The aim of this study was to identify biomarkers for predicting the efficacy of docetaxel, cisplatin, and S-1 (DCS) therapy for advanced gastric cancer using microarrays of biopsy specimens before chemotherapy. Nineteen samples were taken from 19 patients with unresectable metastatic gastric cancer who received DCS as a first-line therapy. Laser capture microdissection was performed, and total cellular RNA was extracted from each microdissected sample. Whole-gene expression was analyzed by microarray, and the difference in mRNA expression observed with the microarrays was confirmed by quantitative real-time PCR. Immunohistochemical staining was performed using clinical tissue sections obtained by endoscopic biopsy. Eleven patients were identified as early responders and 8 patients as nonresponders to DCS therapy. Twenty-nine genes showed significant differences in relative expression ratios between tumor and normal tissues. A classifier set of 29 genes had high accuracy (94.7%) for distinguishing gene expression between 11 early responders and 8 nonresponders. Decreasing the size of the classifier set to 4 genes (PDGFB, PCGF3, CISH, and ANXA5) increased the accuracy to 100%. Expression levels by real-time PCR for validation were well correlated with those 4 genes in microarrays. The genes identified may serve as efficient biomarkers for personalized cancer-targeted therapy.

Efficacy of hybrid endoscopic submucosal dissection (ESD) as a rescue treatment in difficult colorectal ESD cases.,
Digestive Endoscopy, Vol.29, No.suppl.2, 45-52, 2017.

(要約): Endoscopic submucosal dissection (ESD), which provides a higher en bloc resection rate than conventional endoscopic mucosal resection (EMR), is considered to be a useful treatment option for large colorectal tumors. However, colorectal ESD is not widely used because of its technical difficulty, risk of complications and time required. To overcome these drawbacks, a simpler modified technique, ESD with snaring (hybrid ESD), has been developed. The aim of the present study was to retrospectively compare the safety and efficacy of hybrid ESD and conventional ESD for colorectal tumors. Between September 2008 and June 2016, ESD was carried out on 137 lesions and hybrid ESD on 27 lesions. All hybrid ESD cases were carried out as a rescue treatment in difficult ESD cases. We retrospectively investigated procedure time, and the rates of en bloc resection, perforation, bleeding, and local recurrence. In the hybrid ESD group, procedure time was shorter compared with the ESD group (108 ± 59.5 min vs 122 ± 72.2 min), but the en bloc resection rate was lower (66.7% vs 94.2%). However, there were no significant differences in procedure time, or in rates of en bloc resection, perforation and bleeding between the two groups. Local recurrence did not develop in any of our cases. Hybrid ESD as a rescue treatment in difficult ESD cases may be less effective for en bloc resection of large colorectal tumors. Indication for hybrid ESD may be limited to scheduled treatment from the outset and emergency cases with patients who present unstable vital signs during ESD.

A Phase I/II Study of Fixed-dose-rate Gemcitabine and S-1 with Concurrent Radiotherapy for Locally Advanced Pancreatic Cancer,
Cancer Chemotherapy and Pharmacology, Vol.76, No.3, 615-620, 2015.

(要約): This study was conducted to identify the maximum-tolerated dose (MTD) of fixed-dose-rate gemcitabine (FDR-gem) administered concurrently with S-1 and radical radiation for locally advanced pancreatic cancer (LAPC) and to provide efficacy and safety data. Patients with unrespectable pancreatic cancer confined to the pancreatic region were treated with FDR-gem (300-400 mg/m(2), 5 mg/m(2)/min) on days 1, 8, 22, and 29 and 60 mg/m(2) of S-1 orally on days 1-14, 22-35. A total radiation dose of 50.4 Gy (1.8 Gy/day, 28 fractions) was delivered concurrently. Twenty-five patients were enrolled; all were evaluable for toxicity assessment. In phase I, eight patients were treated in sequential cohorts of three to five patients per dose level. The MTD was reached at level 2, and dose-limiting toxicities were neutropenia and thrombocytopenia. The recommended doses were 300 mg/m(2) of gemcitabine and 60 mg/m(2) of S-1 daily. The overall response rate was 25% and disease control rate (partial response plus stable disease) was 92%. The progression-free survival was 11.0 months. The median overall survival and 1-year survival rates were 16.0 months and 73%, respectively. The combination of FDR-gem and S-1 with radiation is a feasible regimen that shows favorable antitumor activity with an acceptable safety profile in patients with LAPC.

Investigation of Gastroduodenal Mucosal Injury in Japanese Asymptomatic Antiplatelet Drug Users,
Medicine, Vol.94, No.26, e1047, 2015.

(要約): Antiplatelet drugs are widely used for the prevention of cardiovascular disease and cerebral vascular disorders. Although there have been several studies on gastroduodenal mucosal injury with gastrointestinal (GI) symptoms such as GI bleeding, in antiplatelet drug users (including low-dose aspirin (LDA)), there have been few reports on the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users. This study was a cross-sectional study elucidating the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Subjects were 186 asymptomatic Japanese antiplatelet drug users who underwent a regular health checkup. Subjects were divided into those with and without gastroduodenal mucosal injury endoscopically, and the association between gastroduodenal mucosal injury and other data in asymptomatic antiplatelet drug users was investigated.The prevalence of males and drinkers were significantly higher in subjects with gastroduodenal mucosal injury than in those without. In addition, the prevalence of proton pump inhibitor (PPI) users was significantly lower in subjects with gastroduodenal mucosal injury than in subjects without gastroduodenal mucosal injury. Logistic regression analysis showed PPI (odds ratios: 0.116; 95% confidence intervals: 0.021-0.638; P < 0.05) was a significant predictor of a decreased prevalence of gastroduodenal mucosal injury and closed-type (C-type) atrophy (3.172; 1.322-7.609; P < 0.01) was a significant predictor of an increased prevalence of severe gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Gender and lifestyle, such as drinking, may have an impact on risk of gastroduodenal mucosal injury in asymptomatic subjects taking antiplatelet drugs. Although PPI is a significant predictor of a decreased prevalence of gastroduodenal mucosal injury, including in asymptomatic antiplatelet drug users, status of gastric atrophy should also be considered against severe gastroduodenal mucosal injury.

Trastuzumab in combination with docetaxel/cisplatin/S-1 (DCS) for patients with HER2-positive metastatic gastric cancer: feasibility and preliminary efficacy.,
Cancer Chemotherapy and Pharmacology, Vol.76, No.2, 375-382, 2015.

(要約): We previously reported that a triplet combination of docetaxel, cisplatin, and S-1 (DCS) is active against metastatic gastric cancer with a very high response rate of 87.1 % in a phase II study. Recently, the efficacy of trastuzumab (T-mab) for the treatment of HER2-positive gastric cancer has been reported. Therefore, we investigated the feasibility and preliminary efficacy of DCS + T-mab (DCS-T) for unresectable HER2-positive metastatic gastric cancer. Patients received oral S-1 (40 mg/m(2) b.i.d.) on days 1-14, intravenous cisplatin (60 mg/m(2)), docetaxel (50 mg/m(2)), and T-mab (8 mg/kg in the first cycle and 6 mg/kg in the second cycle and thereafter) on day 8 every 3 weeks. The study included 16 patients: median age, 60 (34-76) years; males/females, 11:5; intestinal-type/diffuse-type histology, 11:5; and HER2 3+/2+(FISH+), 13:3. The completion rate until the third cycle was 87.5 % (14/16) (95 %CI 71.3-103.7 %). Adverse events of grade 3/4 severity during the first 3 cycles were: leukopenia/neutropenia, 50.0:75.0 %; febrile neutropenia, 12.5 %; diarrhea, 12.5 %; and stomatitis, 12.5 %. All of these side effects were manageable and well controlled. There were no treatment-related deaths. The overall response rate was 93.8 % (15/16), and the response rate in patients with measurable lesions was 100 % (15/15). The median cycle to response was only 1 (1-3 cycles). Non-curative factors disappeared in 56.3 % (9/16) of patients, and conversion surgery (R0 resection) was performed in all these cases. Pathological response rates in primary and metastatic lesions were 88.9 % (8/9) and 100 % (9/9), respectively. The median PFS and OS were not reached during the median follow-up time of 18.3 months ranged from 11.0 to 34.3 months. DCS-T was feasible in patients with unresectable HER2-positive metastatic gastric cancer. The observed response was very promising and warrants further investigation. UMIN000005603.

Gastric inflammatory fibroid polyp morphologically changed by Helicobacter pylori eradication.,
Clinical Journal of Gastroenterology, Vol.8, No.2, 71-88, 2015.

(要約): A 60-year-old male presented to our hospital for further investigation of abnormal findings on an upper gastrointestinal series. Esophagogastroduodenoscopy demonstrated atrophic gastritis and a submucosal tumor (SMT) at the anterior wall of the antrum. The patient was positive for serum anti-Helicobacter pylori (H. pylori) antibody and H. pylori eradication therapy was performed. Five months later, the SMT showed a remarkable morphological change in that an ulcer had developed on its apex, and partial gastrectomy was performed. Pathological examination suggested an inflammatory fibroid polyp (IFP), and genetic analysis revealed no mutation in the platelet-derived growth factor receptor alpha gene. This case suggests that H. pylori infection plays an important role in the etiology of IFPs.

Overview of Chemotherapy for Gastric Cancer.,
Journal of Clinical Medicine, Vol.12, No.4, 1336, Feb. 2023.

(要約): Gastric cancer (GC) is one of the most clinically challenging cancers worldwide. Over the past few years, new molecular-targeted agents and immunotherapy have markedly improved GC prognosis. Human epidermal growth factor receptor 2 (HER2) expression is a key biomarker in first-line chemotherapy for unresectable advanced GC. Further, the addition of trastuzumab to cytotoxic chemotherapy has extended the overall survival of patients with HER2-positive advanced GC. In HER2-negative GC, the combination of nivolumab, an immune checkpoint inhibitor, and a cytotoxic agent has been demonstrated to prolong the overall survival of GC patients. Ramucirumab and trifluridine/tipiracil, which are second- and third-line treatments for GC, and trastuzumab deruxtecan, an antibody-drug conjugate for HER2-positive GC, have been introduced in clinics. New promising molecular-targeted agents are also being developed, and combination therapy comprising immunotherapy and molecular-targeted agents is expected. As the number of available drugs increases, it is important to understand the target biomarkers and drug characteristics and select the optimal therapy for each patient. For resectable disease, differences in the extent of standard lymphadenectomy between Eastern and Western countries have led to different standard treatments: perioperative (neoadjuvant) and adjuvant therapy. This review aimed to summarize recent advances in chemotherapy for advanced GC.

(要約): Recently, immune checkpoint inhibitors(ICI)have been approved for use in advanced gastric cancer(AGC)based on the positive results of ATTRACTION‐2 trial in Japan. There has been accumulating evidence that the development of immune-related adverse events(irAE)may be associated with a response to ICI therapy, particularly in lung cancer, although little is known about these correlations in gastrointestinal cancer. To investigate the efficacy and irAE of ICI treatment and their correlation in AGC, we retrospectively examined 29 patients with AGC who received nivolumab therapy in our departments. Among them, 15 patients(52%)developed irAEs including 4 patients(14%)for grade 3 irAEs ; liver dysfunction(n＝2), type 1 diabetes mellitus(n＝2) and adrenal insufficiency(n＝1). The median overall survival was12．0months in the irAE group and 3．25 months in the non-irAE group(p＝0．164), which suggested the relationship between the effects and irAEs in ICI treatment of AGC. Further research is required to understand the implications of irAE characteristics on ICI response in GCA patients.
