Abstract
OBJECTIVE This study compared the effectiveness, safety, and tolerability of dose-dense paclitaxel and carboplatin plus bevacizumab (ddTC+Bev) with ddTC for advanced ovarian cancer. METHODS We retrospectively analyzed the clinical records of 134 patients who received ddTC+Bev or ddTC as first-line chemotherapy for stage III-IV ovarian cancer. Progression-free survival as primary endpoint of this study was compared using the log-rank test. Cox proportional hazards model and propensity score matching (PSM) were used to analyze prognostic factors, and the frequency of adverse events was examined using the χ² test. RESULTS We categorized 134 patients in the ddTC+Bev (n=57) and ddTC (n=77) groups who started treatment at four related institutions from November 2013 to December 2017. No patients used poly (ADP-ribose) polymerase inhibitors as the first line maintenance therapy. The progression-free survival (PFS) of the ddTC+Bev group had a significantly better prognosis than that of the ddTC group (hazard ratio [HR]=0.50; 95% confidence interval [CI]=0.32-0.79; p<0.003). Multivariate analysis showed that ddTC+Bev regimen was a prognostic factor. However, intergroup comparison using PSM revealed that the PFS of the ddTC+Bev group had a nonsignificantly better prognosis than that of the ddTC group (HR=0.70; 95% CI=0.41-1.20; p=0.189). Few adverse events above G3 were noted for ddTC+Bev, which were sufficiently tolerable. CONCLUSION This study could not demonstrate that adding Bev to ddTC improves prognosis. Further studies with more cases are warranted.

Abstract
Background/Aims Helicobacter pylori infection-negative gastric cancer (HPNGC) has not been systematically investigated in consecutive patients. Hence, this study aimed to investigate the clinicopathological and endoscopic features of HPNGC. Methods This single-center retrospective study selected participants from patients with gastric cancer who were treated at the Fukuoka University Chikushi Hospital between January 2013 and December 2021. Only patients diagnosed with HPNGC were enrolled, and their clinicopathological and endoscopic features were analyzed in detail. Results The prevalence of HPNGC in the present study was 2.6% (54/2112). The types of HPNGC observed in each gastric region were as follows: advanced gastric cancer was observed in the cardia; gastric adenocarcinoma of fundic-gland differentiation, gastric adenocarcinoma of foveolar-type presenting with whitish elevation and raspberry-like foveolar-type gastric adenocarcinoma, gastric adenocarcinoma arising in polyposis, and gastric adenocarcinoma with autoimmune gastritis were observed in the fundic gland region ranging from the gastric fornix to the gastric body; signet-ring cell carcinoma was observed in the gastric-pyloric transition region ranging from the lower gastric body to the gastric angle; and well-differentiated tubular adenocarcinoma with low-grade atypia was observed in the antrum. Conclusions This study revealed that tumors from each gastric region exhibited distinct macroscopic and histological types in HPNGC.

Abstract
BACKGROUND/AIMS Multiple white and flat elevated lesions (MWFL) that develop from the gastric corpus to the fornix may be strongly associated with oral antacid intake. Therefore, this study aimed to determine the association between the occurrence of MWFL and oral proton pump inhibitor (PPI) intake and clarify the endoscopic and clinicopathological characteristics of MWFL. METHODS The study included 163 patients. The history of oral drug intake was collected, and serum gastrin levels and anti-Helicobacter pylori immunoglobulin G antibody titers were measured. Upper gastrointestinal endoscopy was performed. The primary study endpoint was the association between MWFL and oral PPI intake. RESULTS In the univariate analyses, MWFL were observed in 35 (49.3%) of 71 patients who received oral PPIs and 10 (10.9%) of 92 patients who did not receive oral PPIs. The occurrence of MWFL was significantly higher among patients who received PPIs than in those who did not (p<0.001). Moreover, the occurrence of MWFL was significantly higher in patients with hypergastrinemia (p=0.005). In the multivariate analyses, oral PPI intake was the only significant independent factor associated with the presence of MWFL (p=0.001; odds ratio, 5.78; 95% confidence interval, 2.06-16.2). CONCLUSION Our findings suggest that oral PPI intake is associated with the presence of MWFL (UMINCTR 000030144).

Abstract
BACKGROUND Trichophyton benhamiae, an anthropophilic dermatophyte, can cause dermatophytosis in humans and animals with rising zoonotic infections through pets, primarily in Europe. Dermatophytosis from T. benhamiae is often misdiagnosed due to its inflammatory symptoms. We report a case of tinea corporis from T. benhamiae var. luteum in a Japanese woman, contracted from pet Czech degus. CASE The 40-year-old patient developed neck papules resembling acne. Initial treatment with topical antibiotics and steroids exacerbated the rash. Fungal elements were not detected by direct potassium hydroxide examination. Skin biopsy confirmed fungal elements in the stratum corneum and hair follicles, and tinea corporis was diagnosed. Oral terbinafine 125 mg was initiated without topical agents. Erythematous papules appeared on her limbs, determined as a trichophytid reaction. After two months, her skin improved significantly. Fungal culture identified T. benhamiae var. luteum colonies with a yellowish hue. Mating tests classified the strain as Americano-European race (-) with MAT1-1 genotype. This was diagnosed as tinea corporis from T. benhamiae var. luteum, likely transmitted from pet Czech degus. CONCLUSIONS The incidence rate of pet-transmitted cutaneous fungal infections may increase in Japan with the trend to keep exotic pets. Dermatologists must recognize dermatophytosis clinical features from anthropophilic dermatophytes to prevent misdiagnosis and understand evolving nomenclature and pathogenesis.

Abstract
OBJECTIVE Total parietal peritonectomy is gradually being recognized as a surgical option for advanced ovarian cancer; however, evidence regarding its efficacy and safety remains insufficient. Herein, we aimed to assess the short- and long-term post-operative safety profiles of total parietal peritonectomy. METHODS We reviewed the medical records of post-operative morbidity and mortality of patients who underwent cytoreductive surgery with total parietal peritonectomy for stage III and IV ovarian cancer between April 2018 and January 2023. RESULTS Fifty patients were enrolled in the study: 31 who underwent primary cytoreductive surgery and 19 who underwent interval cytoreductive surgery. The median age of all patients was 57 (range, 23-74) years. The median follow-up period was 22 (range, 3-59) months. Of 44 patients (88%) with stage IIIC/IV, 38 patients (76%) had high-grade serous carcinoma. The complete resection rates were 94%, 91%, and 100% in all patients, the primary cytoreductive surgery group, and the interval cytoreductive surgery group, respectively. There were 63 post-operative complication events overall, including 17 (27%) major complication events in 15 patients within 1 year post-operatively. Ten major complications occurred within 30 days of surgery, mainly in the primary cytoreductive surgery group (9 cases). Regarding complication type, the most frequent major event was pleural effusion (3 cases, 7%). After 30 days, there were a total of 17 all-grade complication events, of which ileus and hydronephrosis were major complications in 3 cases each (18%). There were no mortalities related to cytoreductive surgery. The scheduled adjuvant chemotherapy could be completed in 96% of patients. CONCLUSIONS Total parietal peritonectomy is a feasible procedure for managing advanced ovarian cancer. Short- and long-term complications may include pleural effusion and ileus/hydronephrosis, respectively.

Abstract
A man in his 60 s underwent upper gastrointestinal endoscopy at our hospital, which revealed a 30-mm elevated lesion in the upper stomach (main lesion). There were several discolored, flat mucosal lesions and slightly elevated, reddish, subepithelial mass-like lesions (multiple secondary lesions) in the gastric fornix and body. Histopathological examination of several biopsied secondary lesions revealed gastric adenocarcinoma of fundic-gland type (GA-FG) or gastric adenocarcinoma of fundic gland-mucosa type (GA-FGM). The main lesion was suspected to be GA-FGM on magnifying endoscopy with narrow-band imaging. It was removed using endoscopic submucosal dissection for therapeutic and diagnostic purposes. The histopathological diagnosis of the resected lesion was GA-FGM, which was surrounded by two GA-FGM and > 30 GA-FG lesions. Total gastrectomy was considered; however, the patient declined further surgical treatment. Therefore, he was followed up with biannual endoscopy and computed tomography. At five years postoperatively, no tumor growth or metastasis has been observed.

Abstract
OBJECTIVE Most ovarian clear cell carcinomas are resistant to platinum-based chemotherapy, while a small subset shows a positive response. The aim of this study was to clarify the clinical, pathological and genetic characteristics of platinum-sensitive ovarian clear cell carcinomas. METHODS The study included 53 patients with stage III-IV ovarian clear cell carcinoma who had residual tumours after primary surgery and received platinum-based therapy between 2009 and 2018. A retrospective examination of platinum sensitivity was performed using the criterion of ≥6 months from the last day of first-line platinum therapy until recurrence/progression. Cases determined to be platinum-sensitive were subjected to immunohistochemical staining, genomic analyses using target sequencing (i.e. NCC Oncopanel) and homologous recombination deficiency (myChoice® HRD Plus) assays. RESULTS Of the 53 stage III-IV ovarian clear cell carcinoma cases, 11 (21%) were platinum-sensitive. These cases showed better progression-free and overall survival than platinum-resistant cases (hazard ratio = 0.16, P < 0.001). Among the seven sensitive cases whose tumour tissues were available for molecular profiling, five were pure ovarian clear cell carcinoma based on pathological and genetic features, whereas the remaining two cases were re-diagnosed as high-grade serous ovarian carcinoma. The pure ovarian clear cell carcinomas lacked BRCA1 and BRCA2 mutations, consistent with the absence of the homologous recombination deficiency phenotype, whereas two cases (40%) had ATM mutations. By contrast, the two high-grade serous ovarian carcinoma cases had BRCA1 or BRCA2 mutations associated with the homologous recombination deficiency phenotype. CONCLUSION The subset of platinum-sensitive ovarian clear cell carcinomas includes a majority with pure ovarian clear cell carcinoma features that lack the homologous recombination deficiency phenotype.

Abstract
Introduction Robot-assisted surgery is spreading across surgical specialities as a less invasive alternative to conventional laparoscopic and open surgery. Case presentation In this report, robot-assisted total laparoscopic hysterectomy and robot-assisted nephroureterectomy were performed simultaneously for a 69-year-old Japanese female with giant cervical polyp and ureteral cancer. All specimens could be removed from the vagina. The operative time was 379 min, the estimated intraoperative blood loss was 29 mL, and the patient was discharged on the sixth postoperative day without complications. Conclusion We reported our experience with simultaneous robot-assisted nephroureterectomy and robot-assisted total laparoscopic hysterectomy. To our knowledge, this is the first report of simultaneous robot-assisted nephroureterectomy and robot-assisted total laparoscopic hysterectomy surgery.

Abstract
Background and study aims An important therapeutic aim in ulcerative colitis (UC) is endoscopic remission. Although an endoscopic score with white light imaging (WLI) is mainly used to evaluate endoscopic findings, the usefulness of linked color imaging (LCI) has been reported. We evaluated the relationship between LCI and histopathological findings and attempted to establish a new LCI endoscopic evaluation index for UC. Patients and methods This study was conducted at Kyorin University, Kyoto Prefectural University, and Fukuoka University Chikushi Hospital. Ninety-two patients with a Mayo endoscopic subscore (MES) ≤ 1 who underwent colonoscopy for UC in clinical remission were included. LCI index was defined as redness (R) (Grade 0-2), area of inflammation (A) (Grade 0-3), and lymphoid follicles (L) (Grade 0-3). Histological healing was defined as Geboes score < 2B.1. Endoscopic and histopathological scores were determined by central judgment. Results In 92 patients, 85 biopsies from the sigmoid colon and 84 biopsies from the rectum (total 169 biopsies) were evaluated. There were 22, 117, and 30 cases of Grades 0, 1, and 2, respectively in LCI index-R; 113, 34, 17, and five cases of Grades 0, 1, 2, and 3, respectively, in LCI index-A; and 124, 27, 14, and four cases of Grades 0, 1, 2, and 3, respectively, in LCI index-L. Histological healing was achieved in 84.0 % of the cases (142 of 169), and there were significant associations with histological healing or non-healing in LCI index-R ( P = 0.013) and A ( P = 0.0014). Conclusions A new LCI index is useful for predicting histological healing in UC patients with MES ≤ 1 and clinical remission.

Abstract
The development of new treatments for gynecological malignancies has been conducted mainly through collaborative international phase III trials led by the United States and Europe. The survival outcomes of many gynecological malignancies have greatly improved as a result. Recent large-scale genome-wide association studies have revealed that drug efficacy and adverse event profiles are not always uniform. Thus, it is important to validate new treatment options in each country to safely and efficiently provide newly developed treatment options to patients with gynecological malignancies. The Japanese Gynecologic Oncology Group (JGOG) is conducting 5 cohort studies (JGOG 3026, 3027, 3028, 3030, and 3031) to establish real-world data (RWD) of poly(ADP-ribose) polymerase (PARP) inhibitor use in patients with advanced or recurrent epithelial ovarian cancer. The RWD constructed will be used to provide newly developed PARP inhibitors for women with advanced or recurrent ovarian cancer in a safer and more efficient manner as well as to develop further treatment options. In 2022, The JGOG, Korean Gynecologic Oncology Group, Chinese Gynecologic Cancer Society, and Taiwanese Gynecologic Oncology Group established the East Asian Gynecologic Oncology Trial Group to collaborate with East Asian countries in clinical research on gynecologic malignancies and disseminate new knowledge on gynecologic malignancies from Asia. The JGOG will conduct a collaborative integrated analysis of the RWD generated from Asian countries and disseminate real-world clinical knowledge regarding new treatment options that have been clinically implemented.

Abstract
OBJECTIVE To investigate the safety of concurrent chemoradiotherapy after Type 3 radical hysterectomy, focusing on non-hematologic toxicity. METHODS Between January 2010 and December 2017, 236 patients diagnosed with cervical cancer Stages IB1-II (FIGO2008) and who had undergone Type 3 radical hysterectomy at the Jikei Medical University School-related four hospitals were included. Of these 236 patients, 134 had undergone adjuvant concurrent chemoradiotherapy after Type 3 radical hysterectomy (radical hysterectomy + concurrent chemoradiotherapy group), and 102 received no adjuvant therapy after Type 3 radical hysterectomy (radical hysterectomy group). The frequency of non-hematologic toxicities, especially lymphedema, pelvic infection, renal dysfunction, ileus and diarrhea, was investigated in the radical hysterectomy + concurrent chemoradiotherapy and radical hysterectomy groups using univariate and multivariate analyses. In these analyses, age, extent of lymph node dissection and preoperative clinical stage were included as risk factors for five complications. The risk factors for grade ≤ 2 adverse events were statistically evaluated. RESULTS The frequency of lower extremity lymphedema (22 vs. 10%), renal dysfunction (13 vs. 3%), and diarrhea (13 vs. 0%) was significantly higher in the radical hysterectomy + CRRT group than that in the radical hysterectomy group. Logistic regression analysis revealed that adjuvant concurrent chemoradiotherapy significantly affected the occurrence of grade ≥ 2 lymphedema (P < 0.01) and renal dysfunction (P < 0.01). CONCLUSIONS Concurrent chemoradiotherapy after Type 3 radical hysterectomy is associated with a higher incidence of renal dysfunction, lower extremity lymphedema and diarrhea. A more appropriate adjuvant therapy needs to be established.

Abstract
Background/Aims Image-enhanced endoscopy can detect superficial oro-hypopharyngeal squamous cell carcinoma; however, reliable endoscopy of the pharyngeal region is challenging. Endoscopy under general anesthesia during transoral surgery occasionally reveals multiple synchronous lesions that remained undetected on preoperative endoscopy. Therefore, we aimed to determine the lesion detection capability of endoscopy under general anesthesia for superficial oro-hypopharyngeal squamous cell carcinoma. Methods This retrospective study included 63 patients who underwent transoral surgery for superficial oropharyngeal squamous cell carcinoma between April 2005 and December 2020. The primary endpoint was to compare the lesion detection capabilities of preoperative endoscopy and endoscopy under general anesthesia. Other endpoints included the comparison of clinicopathological findings between lesions detected using preoperative endoscopy and those newly detected using endoscopy under general anesthesia. Results 58 patients (85 lesions) were analyzed. The mean number of lesions per patient detected was 1.17 for preoperative endoscopy and 1.47 for endoscopy under general anesthesia. Endoscopy under general anesthesia helped detect more lesions than preoperative endoscopy did (p<0.001, paired t-test). The lesions that were newly detected on endoscopy under general anesthesia were small and characterized by few changes in color and surface ruggedness. Conclusions Endoscopy under general anesthesia for superficial squamous cell carcinoma is helpful for detecting multiple synchronous lesions.

Abstract
BACKGROUND AND AIM Patients with incomplete gastric intestinal metaplasia (GIM) have a higher risk of gastric cancer (GC) than those with complete GIM. We aimed to clarify whether micromucosal patterns of GIM in magnifying endoscopy with narrow-band imaging (M-NBI) were useful for diagnosis of incomplete GIM. METHODS We enrolled patients with a history of endoscopic resection of GC or detailed inspection for suspicious or definite GC. The antrum greater curvature and corpus lesser curvature were regions of interest. Areas with endoscopic findings of light blue crest and/or white opaque substance (WOS) were defined as endoscopic GIM, and subsequent M-NBI was applied. Micromucosal patterns were classified into Foveola and Groove types, and targeted biopsies were performed on GIM with each pattern. GIM was classified into complete and incomplete types using mucin (MUC)2, MUC5AC, MUC6, and CD10 immunohistochemical staining. The primary endpoint was the association between micromucosal pattern and histological subtype. The secondary endpoint was endoscopic findings associated with incomplete GIM. RESULTS We analyzed 98 patients with 156 GIMs. Univariate analysis (odds ratio [OR] 3.4, P = 0.004), but not multivariate analysis (OR 0.87, P = 0.822), demonstrated a significant association between micromucosal pattern and subtype. The antrum (OR 3.7, P = 0.006) and WOS (OR 43, P = 0.002) were independent predictors for incomplete GIM. The WOS had 69% sensitivity and 93% specificity. CONCLUSIONS The M-NBI micromucosal pattern is not useful for diagnosis of GIM subtype. WOS is a promising endoscopic indicator for diagnosis of incomplete GIM. (UMIN-CTR000041119).

Abstract
Background The aim of the trial is to evaluate the effectiveness of interventions provided by online support program apps, adopting health-related quality of life (HR-QOL) scores as indicators. Methods The design is as an open, randomized, parallel-group trial with longitudinal data collection. The subjects will be female cancer patients receiving treatment in a Japanese National Cancer Hospital. Patients assigned to the experimental group will use three apps: an app for them to monitor their own health (monitoring app), an app to assess their understanding of their diagnosis and treatment and their readiness to receive treatment (confirmation app), and an app to address mental health issues (writing app); patients assigned to the control group will use only the monitoring app. At baseline (before patients undergo cancer treatment) and three other times during the study, evaluation indicators will be obtained from three different standardized HR-QOL scales that are incorporated in the monitoring app. The study hypothesis is that at 6 months after patients’ baseline health monitoring, patients in the experimental group will have improved HR-QOL as compared with patients in the control group. Conclusion This study is based on self-regulation theory, so it is important that the online support program works in an efficient way with respect to patients finding and setting their own health-related goals and adapting their behaviors to achieve those goals. Verifying the effectiveness of the combination of the three apps will show that it is a scientifically valid approach to maintaining or improving the HR-QOL of cancer patients.

BACKGROUND/AIM Total parietal peritonectomy (TPP) is a surgical procedure used for complete resection of microscopic peritoneal dissemination. This study analyzed the perioperative complications that developed when omitting systematic lymphadenectomy from TPP. PATIENTS AND METHODS We retrospectively analyzed perioperative complications in epithelial ovarian cancer patients with stage IIIB-IVB who underwent TPP during primary and interval cytoreductive surgeries between April 2018 and October 2021. RESULTS Thirty-three patients were enrolled in the study. The median patient age was 62 years. Of 31 patients (94%) with stage IIIC/IV disease, 24 (73%) had high-grade serous carcinoma. The median operative time and blood loss were 447 min and 2,831 ml, respectively. Complete tumor resection was performed in 30 patients (91%). Only five patients underwent partial lymphadenectomy for clinical metastatic lymph nodes. Further, grade 3 complications were observed in seven (21%) patients, and there were no fatal events in this study. Three patients (9%) had ureteric injuries, which was the most frequent complication in this study. Only one patient developed an intra-abdominal infection due to ascites. In this case, partial para-aortic and pelvic lymphadenectomies were performed. CONCLUSION TPP without systematic lymphadenectomy reduces the frequency of perioperative complications associated with ascites.

Abstract
Abstract
Background: The development of chimeric antigen receptor (CAR) T cell therapy has introduced an effective strategy to guide and promote the immune response. Also, gene-engineering NK cells to express an exogenous CAR receptor allows the innate anti-tumor ability of NK cells to be directed against target tumor antigen. However, these autologous applications are limited by toxicities, restricted trafficking and infiltration into tumor, suboptimal persistence, and exhausted status of immune cells that may cause manufacturing failure. One approach to overcome those limitations is the development of “off-the-shelf” iPS-cell sources. The iCAR-ILC-N101 is an allogeneic human leukocyte antigen (HLA)-homozygous induced pluripotent stem cell (iPSC)-derived anti-glypican-3 (GPC3) CAR-expressing innate lymphoid cells/natural killer cell (ILC/NK), which has both antigen-specific and NK activating receptor-mediated cytotoxicity. The iCAR-ILC-N101 is produced from the established iPSC strain QHJI01s04, and there is theoretically no risk of developing graft-versus host disease because the product dose not have T cell receptor. The product has a relevant living period in the body, thereby has little concern about residual toxicity and reduces systemic side effects by topical treatment. GPC3 is a cancer-specific membranous protein that is expressed in hepatoblastoma, hepatocellular carcinoma and ovarian clear cell carcinoma (OCCC) but is not expressed in normal tissue. OCCC is a relatively rare malignancy and is associated with poor prognosis. Intraperitoneal administration of iCAR-ILC-N101 is expected to show antitumor activity for OCCC patients with peritoneal dissemination that express GPC3 and reduce systemic side effects, thereby ensuring safety and improving therapeutic efficacy. Preclinical study showed that intraperitoneal injection of iCAR-ILC-N101 for GPC3-positive ovarian tumor-bearing immunodeficient mouse model showed suppressed tumor growth.
Method: This is a first-in human phase 1 study to evaluate safety, toxicity and efficacy of the iCAR-ILC-N101 in patients with GPC3-positive advanced or recurrent OCCC harboring peritoneal dissemination. Major inclusion criteria include histologically diagnosed GPC3-positive advanced or recurrent OCCC with peritoneal dissemination who are resistant to standard therapy and have matched HLA-A24 or B52. The study includes 3 cohorts (cohort -1, 0.5x106 cells/kg; cohort 1, 1x106 cells/kg; cohort 2, 3x106 cells/kg) and starts with cohort 1. The iCAR-ILC-N101 is administered intraperitoneally once a week for 4 weeks; for the first patient in each cohort, patient is observed for 14 days for safety evaluation after the first administration and then receive iCAR-ILC-N101 on day15 and 22. Enrollment initiated in July 2021 and one patient was enrolled. No dose-limiting toxicity was observed. Clinical trial registry number: jRCT2033200431

Abstract
This study evaluated the feasibility and efficacy of three postoperative adjuvant chemotherapy regimens for endometrial cancer. Endometrioid cancer patients with intermediate-risk stage I and II or high-risk stage III and IV disease were randomly assigned to receive six cycles of either Paclitaxel-Epirubicin-Carboplatin (TEC), Paclitaxel-Anthracycline (Doxorubicin)-Carboplatin (TAC), or dose-dense paclitaxel-carboplatin (ddTC). The primary endpoint was the completion rate (CRate) of six cycles of treatment. The secondary endpoints were progression-free survival (PFS) and overall survival (OS). One hundred and one patients were treated as follows: 33 received TEC, 33 TAC, and 35 ddTC. The CRates for TEC, TAC and ddTC were 94%, 64% and 69%, respectively (p=0.005). The TEC CRate was significantly higher than for the other two groups. However, the PFS and OS outcomes were not statistically different between the three groups. The two-year survival rates were 94%, 97%, and 97% for TEC, TAC, and ddTC, respectively. When compared to the current standard treatments for endometrial cancer, TEC is a promising candidate for a phase III trial based on its significantly superior CRate and equivalent PFS and OS. This study is registered with UMIN Clinical Trials Registry (UMIN000008911).

Abstract
BACKGROUND/AIM We investigated the predictive value of scoring systems of peritoneal disseminations for complete surgery (CS) at primary debulking surgery (PDS) in advanced ovarian cancer. PATIENTS AND METHODS We retrospectively enrolled eligible patients with clinical stages III or IVA selected for PDS from January 2015 to December 2019. Concern variables were predictive index value (PIV) and peritoneal cancer index (PCI) from operative and pathological reports. Primary endpoints were cutoffs to predict operative completeness using the receiver operating characteristic curve. RESULTS Among 111 patients, PIV ≥8 and PCI ≥13 were the best predictors of incomplete PDS, including optimal and suboptimal surgeries (AUC=0.821 and 0.855, respectively). CS rates in PIV ≤6 and PCI ≤12 were significantly higher than in PIV ≥8 (89.3% vs. 47.2%; p<0.05) and PCI ≥13 (90.9% vs. 41.2%: p<0.05). CONCLUSION PIV and PCI are potential predictors for CS at PDS.

Abstract
Many clinical trials have been conducted for inflammatory bowel disease (IBD), so various clinical indices (CIs) and endoscopic indices (EIs) have also been evaluated. However, recently, with the progress of IBD management, review of established indices from previous studies, and establishment of new indices, the landscape of the use of indices in clinical trials have changed. We investigated the number and frequency of the indices adapted in recent clinical trials for ulcerative colitis (CI and EI) and Crohn's disease (CI, EI, index related to magnetic resonance imaging, index for evaluating patient-reported outcomes, and health-related quality of life). Based on the results, we selected representative indices and further reviewed their content and characteristics. Moreover, various definitions, including clinical and endoscopic response or remission, have been described by means of representative indices in clinical trials.

Abstract
BACKGROUND AND STUDY AIMS Gastric adenocarcinoma of fundic-gland type (GA-FG) was first proposed as a new entity of gastric adenocarcinoma in 2010. Subsequently, gastric adenocarcinoma of fundic-gland mucosa type (GA-FGM) was reported as a subtype of gastric adenocarcinoma. This study aimed to investigate the endoscopic findings of GA-FGM and to evaluate the differences between GA-FGM and GA-FG. PATIENTS AND METHODS This was a single-center retrospective study. Participants were selected from patients with gastric cancer treated at Fukuoka University Chikushi Hospital, between September 2007 and May 2020. Patients histologically diagnosed with GA-FGM or GA-FG were enrolled, and endoscopic findings were analyzed in detail. RESULTS A total of 12 GA-FGM lesions (12 patients) and 14 GA-FG lesions (13 patients) were analyzed. The two lesion types showed similar features: most lesions were of elevated type, located in the upper stomach, and developed in the stomach without Helicobacter pylori infection. On conventional endoscopy using the dye-spraying method, well-demarcated fine granular areas were observed in 7 GA-FGM lesions (58%) but not in any GA-FG lesions, with a significant difference between the two groups (P = 0.001). Magnifying endoscopy with narrow-band imaging (NBI) showed that 11 GA-FGM lesions (92%) met the diagnostic criteria for cancer according to the vessel plus surface classification system, whereas none of the GA-FG lesions met the same criteria (0%, 0/14) (P = 0.001). CONCLUSION Our results suggest that magnifying endoscopy with NBI is a potentially useful method for the diagnosis of GA-FGM.

Abstract
BACKGROUND Pancreatic cancer is one of the lethal cancers among solid malignancies. Pathological diagnosis of surgical margins is sometimes unreliable due to tissue shrinkage, invisible field cancerization and skipped lesions like tumor budding. As a result, tumor recurrences sometimes occur even from the pathologically negative surgical margins. METHODS We applied molecular surgical margin (MSM) analysis by tissue imprinting procedure to improve the detection sensitivity of tiny cancerous cells on the surgical specimen surface after pancreatoduodenectomy. Surgical specimens were collected from 45 pancreatic cancer cases who received subtotal stomach preserving pancreatoduodenectomy at Nagoya University Hospital during 2017-2019. Quantitative methylation-specific PCR (QMSP) of the original methylation marker panel (CD1D, KCNK12, PAX5) were performed and analyzed with postoperative survival outcomes. RESULTS Among 45 tumors, 26 cases (58%) were QMSP-positive for CD1D, 25 (56%) for KCNK12 and 27 (60%) for PAX5. Among the 38 tumors in which at least one of the three markers was positive, CD1D-positive cancer cells, KCNK12-positive cancer cells, and PAX5-positive cancer cells were detected at the surgical margin in 8 cases, 7 cases and 10 cases, respectively. Consequently, a total of 17 patients had at least one marker detected at the surgical margin by QMSP, and these patients were defined as MSM-positive. They were associated with significantly poor recurrence-free survival (p = 0.002) and overall survival (p = 0.005) than MSM-negative patients. Multivariable analysis showed that MSM-positive was the only significant independent factor for worse recurrence-free survival (hazard ratio: 3.522, 95% confidence interval: 1.352-9.179, p = 0.010). On the other hand, a significant proportion of MSM-negative cases were found to have received neoadjuvant chemotherapy (p = 0.019). CONCLUSION Pancreatic cancer-specific methylation marker panel was established to perform MSM analysis. MSM-positive status might represent microscopically undetectable cancer cells on the surgical margin and might influence the postoperative long-term outcomes.

Abstract
An innovative tangential-view soft x-ray (SXR) tomographic imaging measurement was developed on the TS-6 spherical tokamak merging device as a key diagnostic for investigating the mechanism of electron acceleration. In order to measure SXR with different energy ranges, two micro-channel plates (MCPs) are, respectively, installed in two vacuum chambers, which are equipped with different filters. Especially designed lenses and fiber bundles serve as an optical system to transfer images from phosphor plates of MCPs to a high speed imaging system. This design also enables us to simultaneously measure two images appearing on phosphor plates of MCPs by just one high speed imaging system. The temporal and spatial resolution of this diagnostic can be up to 5 µs and 4 mm, respectively, at present. The tomographic method based on the Phillips-Tikhonov regularization is employed to reconstruct line-integrated images into the local emissivity of SXR, which reflects the spatial distribution of high-energy electrons. Owing to this diagnostic, we successfully measured SXR emitted from the downstream region of magnetic reconnection in TS-6 merging experiments for the first time. The energy range of SXR turned out to be higher than 100 eV but lower than 400 eV.

Abstract
Background and study aims A white opaque substance (WOS) has been observed in the epithelia of gastric, duodenal, and colorectal epithelial adenomas and carcinomas, using magnifying endoscopy (ME). The WOS has been reported to be derived from a dense accumulation of minute lipid droplets in the epithelium. This study aimed to investigate whether the WOS in colorectal hyperplastic polyps was derived from lipid droplets accumulated in the epithelium, as observed in the case of gastric, duodenal, and colorectal epithelial neoplasms. Patients and methods We analyzed 30 consecutive patients who were positive for the WOS, as visualized in colorectal hyperplastic polyps by ME with narrow-band imaging and 30 consecutive patients who were negative for the WOS. Biopsy specimens obtained from the polyps were immunostained with anti-adipophilin antibody to determine the correlation between the presence of the WOS and that of lipid droplets in the epithelium. Results In all patients, the epithelial cells were histologically positive for adipophilin. However, the area of adipophilin-positive epithelial cells in the WOS-positive group was significantly larger than that in the WOS-negative group ( P < 0.001). The density of the WOS was strongly and positively correlated with the area of adipophilin-positive cells. Conclusions This study reveals that the WOS visualized in the superficial layers of colorectal hyperplastic polyps is produced by a dense accumulation of minute lipid droplets in the epithelia of the polyps.

Abstract
Colonic diverticular could bleed recurrently, and, sometimes, fatal massive bleeding could occur. However, the choice of endoscopic hemostasis remains controversial. Although the over-the-scope clip (OTSC) method has been reported to be effective, it has not been fully evaluated due to the small number of cases. This study aimed to evaluate the efficacy of the OTSC method for colonic diverticular bleeding. Between August 2017 and December 2020, 36 consecutive patients, including those who could not be treated using endoscopic band ligation (EBL) and those in whom re-bleeding had occurred after EBL, underwent the OTSC method for hemostasis of colonic diverticular bleeding at Hyogo Prefectural Awaji Medical Center. The procedure success rate, adverse events rate, early phase re-bleeding rate (within 30 days following primary hemostasis), and the requirement rate for additional transcatheter arterial embolization (TAE) or surgery were the outcomes assessed. The outcomes were procedure success rate 100%, adverse events rate 0%, early phase re-bleeding rate 8.3%, and additional TAE or surgery rate 0%. These results suggest that the OTSC method is a safe and effective treatment for managing colonic diverticular bleeding.

Abstract
The object of this study is to evaluate the clinical safety and efficacy of total parietal peritonectomy (TPP) in primary debulking surgery (PDS) for advanced ovarian cancer. This retrospective single-center study analyzed 16 patients with FIGO stages IIIC-IVB epithelial ovarian cancer who underwent TPP in PDS and achieved macroscopically complete resection between April 2015 and June 2016. The median age of 16 patients was 52.5 years old. 12 were in stage IIIC and 4 were in stage IV. Regarding intraoperative complications, unintended diaphragm perforation was observed in two patients. Regarding postoperative complications (Clavien-Dindo classification grade 3-5) before the adjuvant chemotherapy, lymph cysts occured in 3 patients, intra-abdominal abscess in 3, ileus in 2, pancreatic fistula in 1 and temporary kidney failure in 1. Regarding postoperative complications (grade 3-5) after the initiation of adjuvant chemotherapy, diaphragmatic hernia occured in 1 patient, ileus in 2 and intra-abdominal abscess in 2. Except 1 patient who relapsed approximately one month from surgery and died, the other 15 patients overcamed complications and recovered without problems in daily life. This analysis was conducted 3 years after all patients underwent PDS, with the 3-year progression-free and overall survival of 62.5% (95% confidence interval [CI], 34.9-81.1) and 87.5% (95 %CI, 58.6-96.7), respectively. Based on the above results, TPP in PDS may improve the prognosis compared to previous reports such as LION trial. On the other hand, complications may increase. Therefore, further studies are necessary on its safety and efficacy.

Abstract
Background It has been reported that it is sometimes difficult to make a diagnosis of gastric cancer detected after Helicobacter pylori (H. pylori) eradication. Therefore, we conducted a study to determine the usefulness of magnifying endoscopy using vessel plus surface classification system for making a diagnosis of early gastric cancer after H. pylori eradication. Method Usefulness of the markers of the vessel plus surface classification system for diagnosing gastric cancer using magnifying endoscopy with narrow-band imaging was investigated for gastric cancer detected after H. pylori eradication (H. pylori-eradicated group) vs. H. pylori-positive gastric cancer (H. pylori-positive group). Results 85 lesions were included in this study. The H. pylori-eradicated group comprised 27 lesions, whereas the H. pylori-positive group comprised 58 lesions. As for magnified endoscopic findings based on the vessel plus surface classification system, the respective positivity rates in the H. pylori-eradicated group vs. those in the H. pylori-positive group were as follows: demarcation line, 100% (27/27) vs. 100% (58/58); irregular microvascular pattern, 100% (27/27) vs. 100% (58/58); and irregular microsurface pattern, 78% (21/27) vs. 95% (55/58). There was no significant difference in the positivity rates of the demarcation line and irregular microvascular pattern between the groups. The positivity rate of the irregular microsurface pattern was significantly lower in the H. pylori-eradicated group than in the H. pylori-positive group (P=0.03). Conclusion We presume that the microvascular pattern is more useful than the microsurface pattern as a diagnostic marker in cases of gastric cancer detected after H. pylori eradication.

Abstract
BACKGROUND/AIM We aimed to analyse the prognosis of patients who underwent primary debulking surgery (PDS) and those who underwent interval debulking surgery (IDS) following four courses of paclitaxel+ carboplatin as preoperative chemotherapy to examine the usefulness of preoperative chemotherapy. PATIENTS AND METHODS We included 45 patients with epithelial ovarian and peritoneal cancers accompanied with diaphragmatic lesions who underwent standard surgery combined with diaphragmatic surgery at two related institutions in January 2010-December 2013. Using medical records, we surveyed the recurrence period, recurrence site, and date of last confirmed survival, and analysed prognosis. RESULTS The PDS and IDS groups comprised 32 and 13 patients (overall survival, 61.2 and 43.2 months), respectively. Progression-free survival in the PDS and IDS groups was 31.2 and 16.8 months, respectively. CONCLUSION NAC-IDS can be a standard treatment option for patients with a tumour in the triangular ligament, in whom complete surgery is difficult.

Abstract
Background and study aims Upper gastrointestinal endoscopy and biopsy are useful for differential diagnosis of Crohn's disease (CD) of the large intestine and ulcerative colitis (UC). We aimed to identify novel histopathological and endoscopic findings in the upper gastrointestinal tract in patients with CD who did not have Helicobacter pylori infection. Patients and methods Upper gastrointestinal endoscopy was performed on patients with CD and UC. Mucosal lesions detected were subsequently observed using magnifying endoscopy with narrow-band imaging (M-NBI), following which biopsy was performed. When no mucosal lesion was detected on conventional endoscopy, M-NBI and biopsy were performed on four sites: the gastric body, gastric antrum, duodenal bulb, and second portion of the duodenum. Results The prevalences of gastric metaplasia (GM) were 48 % (24/50) and 16 % (8/50) in the CD and UC groups, showing a significant difference ( P = 0.001). In 23 of 24 patients with histologically proven GM in the CD group, mucosal lesions were detected using conventional white-light imaging (C-WLI). In 22 of 24 patients with histologically proven GM in the CD group, disappearance of normal villous structure and the presence of curved marginal crypt epithelium were noted using magnifying endoscopic findings characteristic of GM (M-GM). A combination of C-WLI and M-NBI yielded a significantly increased specificity ( P = 0.004) and accuracy ( P = 0.039). Conclusions The prevalence of GM in the duodenal mucosa was significantly higher in patients with CD than in controls. The identified endoscopic findings may be useful as novel indicators for the histological diagnosis of GM in the duodenum.

Abstract
Background/Aims A white substance that is opaque to endoscopic light is sometimes observed in the epithelium during narrowband imaging with magnifying endoscopy of gastric or colorectal epithelial neoplasms. This prospective observational study aimed to determine whether the morphology of the white opaque substance (WOS) allows differential diagnosis between colorectal adenoma and carcinoma.
Methods A consecutive series of patients with colorectal adenomas or early carcinomas who underwent endoscopic resection or surgical excision were studied. The morphology of the WOS was determined based on endoscopic images before the histopathological diagnosis was performed. The primary outcome was the diagnostic performance of an irregular WOS as a marker of colorectal carcinoma.
Results The study analyzed 125 lesions. A total of 33 lesions showed an irregular WOS, and 92 lesions showed a regular WOS. Among the 33 lesions found to show an irregular WOS, 30 were carcinomas. Among the 92 lesions showing a regular WOS, 79 were adenomas. With irregular WOS as a marker of carcinoma, the diagnostic accuracy was 87%, sensitivity was 91%, and specificity was 86%.
Conclusions This study demonstrated the potential usefulness of the morphology of the WOS as a marker for the differential diagnosis between adenoma and carcinoma in cases of colorectal epithelial neoplasms.

Abstract
BACKGROUND/AIMS The objective of this study was to elucidate the histological structure of the absent microsurface patterns (MSPs) that were visualized by magnifying endoscopy with narrow-band imaging (M-NBI). METHODS The study included consecutive gastric epithelial neoplasias for which M-NBI findings and histological findings could be compared on a one-to-one basis. The lesions were classified as absent MSPs and present MSPs based on the findings obtained using M-NBI. Of the histopathological findings for each lesion that corresponded to M-NBI findings, crypt opening densities, crypt lengths, crypt opening diameters, intercrypt distances, and crypt angles were measured and compared. RESULTS Thirty-six lesions were included in the analysis; of these, 17 lesions exhibited absent MSP and 19 lesions exhibited present MSP. Comparing the histological measurements for absent MSPs vs. present MSPs, median crypt opening density was 0.9 crypt openings/mm vs. 4.8 crypt openings/mm (p<0.001), respectively. The median crypt length, median crypt opening diameter, median intercrypt distance, and median crypt angle were 80.0 μm vs. 160 μm (p<0.001), 40.0 μm vs. 44.2 μm (p=0.09), 572.5 μm vs. 166.7 μm (p<0.001), and 21.6 degrees vs. 15.5 degrees (p<0.001), respectively. CONCLUSION Histological findings showed that lesions exhibiting absent MSPs had lower crypt opening density, shorter crypt length, greater intercrypt distance, and larger crypt angle.

Abstract
Adenocarcinomas with differentiation towards fundic or pyloric glands are rare histological subtypes. We herein describe two cases of new histological subtypes: mixed fundic and pyloric mucosa-type adenocarcinoma detected in Helicobacter pylori uninfected patients. The first patient was a woman in her 40s. A glossy, reddish, nodular lesion with a flat elevated whitish area was detected at the gastric fundus. When the nodular lesion was visualised with magnifying narrow-band imaging (M-NBI), an absent microvascular pattern plus an irregular microsurface pattern with a demarcation line was observed. The second patient was a woman in her 60s. A glossy, reddish, elevated lesion was detected at the gastric body. M-NBI finding was a regular microvascular pattern plus a regular microsurface pattern with a demarcation line. Histological examination of the resected specimens from both cases showed a very well- to well-differentiated adenocarcinoma which has differentiation towards the mixed fundic and pyloric mucosa. The histological and serological findings of both cases indicated the absence of H. pylori infection. The present two cases demonstrate further evidence of a new histological subtype of gastric adenocarcinoma: mixed fundic and pyloric mucosa-type adenocarcinoma, which has distinct characteristic endoscopic findings.

Abstract
BACKGROUND Reports show miR-23b to be a cancer-related biomarker in various cancer types. Interestingly, it has a dual role of oncogenic and tumor-suppressive functions, depending on the cancer type. This study focused on the unknown association of miR-23b-3p with hepatocellular carcinoma (HCC). METHODS Expression of miR-23b-3p was measured in nine HCC cell lines and 125 resected human HCC samples by TaqMan microRNA assays. To detect its downstream target, miR-23b-3p mimic and inhibitor constructs were transfected and analyzed. RESULTS HepG2, a high miR-23b-3p-expressing cell line, was transfected with a miR-23b-3p inhibitor construct, whereas SK-Hep1, a low miR-23b-3p-expressing cell line, was transfected with a mimic construct. Proliferation of HCC cells was activated by miR-23b-3p overexpression and diminished by its knockdown. Then, 125 clinical HCC samples were examined to measure miR-23b-3p expression. Tumor expression of miR-23b-3p was upregulated in 48 cases (38%) and downregulated in 77 cases (62%). The upregulated cases were correlated with elderly patients (P = 0.015). These patients also showed significantly poor overall survival [hazard ratio (HR), 3.10; 95% conflidence interval (CI), 1.57-6.29; P = 0.001] in a multivariate analysis. Furthermore, mitochondrial metabolism-related genes (MICU3 and AUH) were detected as specific binding targets. CONCLUSION The study showed that miR-23b-3p functions as an oncogenic microRNA in HCC cell lines. Its overexpression in resected HCC tissues was a significant prognostic factor of overall survival. Both MICU3 and AUH may be candidate gene targets of miR-23b-3p.

Abstract
This paper provides an overview of the principles of a vessel plus surface (VS) classification system to explain the diagnostic system of early gastric cancer using image-enhanced magnifying endoscopy. Furthermore, this paper introduces the magnifying endoscopy simple diagnostic algorithm for gastric cancer (MEADA-G) developed according to the VS classification system, with a description of the procedures performed for diagnosis. In addition to the diagnostic system, white opaque substance (WOS), light blue crest (LBC), white globe appearance (WGA), and vessels within epithelial circle (VEC) patterns, which are representative findings that can be observed in the gastric mucosa by image-enhanced magnifying endoscopy, are also described. Image-enhanced magnifying endoscopy is particularly useful in the diagnosis of differentiated-type early gastric cancer. It is important to use the appropriate clinical strategies based on a comprehensive understanding of the usefulness and limitations of the diagnostic system described in this paper.

Abstract
BACKGROUND The Apolipoprotein-related MORtality RISk (AMORIS) study in Sweden revealed that serum uric acid (SUA) was significantly associated with hepatobiliary cancer occurrence. However, the association with postoperative hepatocellular carcinoma (HCC) recurrence has not been reported. METHODS A total of 256 surgically resected HCC patients were included (from January 2003 to December 2017) in this study. Comparisons in terms of clinicopathologic factors and long-term outcomes were made between patients with high SUA (>6.1 mg/dl) at the time of hepatectomy and low SUA. Besides, SUA data at one postoperative year (1POY) of the same cohort were collected and analyzed in the same manner. RESULTS About 88.8% of tumor relapse sites were the remnant liver. High SUA levels were associated with male and well-differentiated HCCs. Recurrence-free survival (RFS) of high SUA patients was significantly inferior to low SUA patients [median survival time (MST): 22.7 vs. 28.5 mo, P = 0.033], whereas no difference was observed in overall survival (MST: both not reached, P = 0.771). RFS of high SUA patients at 1POY also showed significantly poorer outcomes than low SUA patients (MST: 29.3 vs. 57.0 mo, P = 0.049). CONCLUSIONS High SUA implies a significant risk factor of activating hepatocarcinogenesis. Keeping the SUA level low may be recommended after HCC resections.

Abstract
Background and study aims Magnifying endoscopy with narrow-band imaging (M-NBI) is reported to be useful in diagnosing invasion depth of superficial esophageal squamous cell carcinoma (SCC), but accurate diagnosis of deep submucosal invasion (SM2) has remained difficult. However, we discovered that irregularly branched microvessels observed with M-NBI are detected in SM2 cancers with high prevalence. Thus, this retrospective study aimed to investigate the diagnostic performance of irregularly branched microvessels as visualized by M-NBI for predicting SM2 cancers. Patients and methods Patients with superficial esophageal SCC lesions that were endoscopically or surgically resected at our hospital between September 2005 and December 2014 were included. Endoscopic findings by M-NBI of these lesions were presented to an experienced endoscopist who was unaware of the histopathological diagnosis and who then judged whether irregularly branched microvessels were present. Using the invasion depth according to postoperative histopathological diagnosis as the gold standard, we determined the diagnostic performance of the presence of irregularly branched microvessels as an indicator for SM2 cancers. Results A total of 302 superficial esophageal SCC lesions (228 patients) were included in the analysis. When irregularly branched microvessels were used as an indicator of SM2 cancers, the diagnostic accuracy was 94.0 % (95 % confidence interval [CI]: 91.1-96.1 %), sensitivity was 79.4 % (95 % CI: 66.6-88.4 %), specificity was 95.9 % (95 % CI: 94.3-97.0 %), positive predictive value was 71.1 % (95 % CI: 59.6-79.1 %), and negative predictive value was 97.3 % (95% CI: 95.7-98.5 %). Conclusions Irregularly branched microvessels may be a reliable M-NBI indicator for the diagnosis of cancers with deep submucosal invasion.
