RESUMEN
BACKGROUND: The post-insertion clinical course of esophageal self-expandable metal stents (SEMS) in initially frail patients with esophageal carcinoma (EC) with dysphagia remains unclear. This study aimed to assess dysphagia improvement and evaluate prognosis in initially frail patients with advanced EC following SEMS insertion. METHODS: We retrospectively reviewed EC patients with EC who underwent esophageal SEMS insertion at our institution between January 2014 and March 2023. Inclusion criteria comprised Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≥ 3 or ECOG PS 2 for individuals aged ≥ 75 years and recommendation for best supportive care by a multidisciplinary team. RESULTS: Forty-six patients met the inclusion criteria. Among them, 37 patients (80.4%) were ≥ 75 years old, and 21 patients (45.7%) exhibited ECOG PS 3 or 4. Dysphagia score (DS) ≥ 3 was observed in 27 patients (58.7%). All esophageal SEMS insertions were successfully completed. Post-procedure, there were two fatal cases of aspiration pneumonia and one perforation incident. DS improved to ≤ 1 in 25 patients (54.3%), with multivariate analysis indicating DS 3-4 and Glasgow Prognostic Score (GPS) 1-2 as negative predictive factors. The median overall survival was 4.1 months (95% confidence interval 1.8-6.5). CONCLUSIONS: Esophageal SEMS insertion effectively alleviated dysphagia in initially frail EC patients, yet prognosis remained poor, with occurrences of some fatal adverse events. Careful selection of candidates for esophageal SEMS insertions is crucial in this demographic, particularly considering the challenges in improving dysphagia for patients with DS 3-4 and GPS 1-2.

BACKGROUND: Recent studies have reported the therapeutic use of endoscopic submucosal dissection (ESD) using an ultrathin endoscope for targeting pharyngeal and distal side lesions in the stenosis or as a less invasive treatment via the nasal route. However, the effectiveness and safety of these treatments remain undetermined. Therefore, this study aimed to review treatment outcomes and discuss the advantages and precautions of the treatments based on our experience. METHODS: This study included 13 patients with 14 lesions who underwent 14 sessions of upper gastrointestinal ESD using an ultrathin endoscope between December 2021 and August 2023. The outcome measures included lesion background, en bloc resection rate, en bloc complete resection rates, and incidence of adverse events (including post-operative bleeding, intraoperative perforation, and delayed perforation). RESULTS: The lesions in the esophagus, stomach, and duodenum were eight, three, and three, respectively, and the median length (range) of each located lesion was 16.5 (6-26), 17 (9-36), and 10 (4-16) mm, respectively. En bloc resection and en bloc complete resection rates were 100 and 92.9%, respectively. The only adverse event was an intraoperative perforation observed during duodenal ESD, resulting from the assistant's inadvertent expansion of the SOUTEN at the final dissection stage. CONCLUSION: Our results demonstrate that ESD with an ultrathin endoscope effectively reaches lesions in difficult locations and enables treatment within a small working space. Therefore, ESD using an ultrathin endoscope is a treatment option for lesions located distally to gastrointestinal stenosis, highly fibrotic lesions, and duodenal tumors.

BACKGROUND/OBJECTIVES: Pancreatic adenosquamous carcinoma (PASC) is a rare variant of pancreatic ductal adenocarcinoma (PDAC). The usual treatment for metastatic or recurrent PASC is systemic chemotherapy in accordance with the PDAC treatment strategy. This study aimed to investigate the efficacy of chemotherapy, especially the benefit of recent combination therapies, in patients with metastatic or recurrent PASC. METHODS: We conducted a multicenter retrospective analysis of 116 patients with metastatic or recurrent PASC treated with first-line chemotherapy between April 2001 and December 2017 at 24 Japanese institutions. RESULTS: Combination chemotherapies included gemcitabine + nab-paclitaxel (GnP, n = 28), fluorouracil/leucovorin + irinotecan + oxaliplatin (FFX, n = 10), gemcitabine + S-1 (GS, n = 10), and others (n = 9). Monotherapies included gemcitabine (n = 51) and S-1 (n = 8). The median overall survival (OS) was 6.5, 7.3, and 4.3 months for the whole cohort, the combination therapy group, and the monotherapy group, respectively. Multivariate analysis indicated that combination therapy showed a better trend in OS than monotherapy (hazard ratio = 0.68; 95% confidence interval, 0.38-1.20). GnP or FFX were selected in 58.7% of patients after FFX was approved in Japan, and revealed a median OS, median progression-free survival, and objective response rate of 7.3 months, 2.8 months, and 26.9% in GnP and 7.2 months, 2.3 months, and 20.0% in FFX respectively. CONCLUSIONS: This study suggests that combination therapy may be more effective than monotherapy. GnP and FFX showed similar and clinically meaningful efficacy for patients with metastatic or recurrent PASC.

BACKGROUND: Gastric tube cancer (GTC), whose usual histology is adenocarcinoma, occurs frequently as a result of improved survival after esophagectomy. Whether endoscopic resection (ER) for GTC is safe and suitable and guidelines for treatment and follow-up remains unclear. METHODS: Patients with GTC who underwent ER at Kanagawa Cancer Center Hospital between 1997 and 2020 were studied retrospectively to evaluate clinical characteristics and short- and long-term outcomes. RESULTS: Twenty-two consecutive patients with 43 lesions were treated in 42 sessions of ER. Lesions were discovered at a median of 9.0 (0-21.8) years after esophageal surgery. Nine (40.9%) patients had multiple lesions at the time of the initial ER session. However, six (54.5%) of the 11 co-existing lesions were overlooked. The location of the middle third was an estimated risk factor for overlooking (p = 0.028). In endoscopic submucosal dissection (ESD) cases, the en bloc dissection rate was as high as 97.1%, and the rates of bleeding, perforation, and aspiration pneumonitis were 17.6%, 0%, and 2.9%, respectively. The bleeding rate was relatively higher than that in usual gastric ESD. Twelve patients (54.5%) experienced synchronous and/or metachronous multiple GTCs during their life span. Thirteen (61.9%) patients died during the median follow-up period of 5.9 (0.7-15.5) years. One patient (7.7%) died of GTC recurrence, 15.4 years after the initial non-curative ER date; 3 (23.1%) patients died of esophageal cancer recurrence, and 3 (23.1%) died of other organ malignancies. The 5-year overall survival rate was 85.0%, and the 5-year disease-specific survival rate was 100%. CONCLUSIONS: ER is feasible for GTCs. However, the rate of bleeding was high in ESD cases. Life-long endoscopic screening of metachronous lesions is desirable. Care should be taken not to overlook lesions in the middle third of the gastric tube. Early detection of esophageal cancer recurrence and other organ malignancies may improve prognosis.

BACKGROUND: Sarcopenia is diagnosed with the skeletal muscle index (SMI) or the sarcopenia index (SI). We previously reported that the ratio of skeletal muscle mass to body fat mass (SF ratio) was a novel index of sarcopenia in patients with non-alcoholic fatty liver disease (NAFLD). The aim of this retrospective study was to evaluate sarcopenia with these indices in patients with NAFLD. METHODS: One hundred and fifty-six consecutive patients with biopsy-proven NAFLD and alanine aminotransferase (ALT) >40 IU/L were enrolled. Liver function and body composition were evaluated in 121 patients after 12 months. We evaluated the relationship between histological findings, changes in liver function, and the SMI, SI, and SF ratio. RESULTS: Of the 156 patients enrolled, 13.5% and 26.3% were diagnosed with sarcopenia with the SMI and SI. In patients with hepatic fibrosis stage <2, the SI and the SF ratio were significantly greater than in patients with fibrosis stage ≥2. There was no difference in SMI between groups. In the cohort assessed at baseline and 12 months later, transaminase activity and SMI decreased significantly, and the SF ratio increased over time. A multivariate analysis revealed the presence of the PNPLA3 G allele and an increase in SF ratio (odds ratio, 7.406) as predictive factors of ALT reduction >30% from baseline. CONCLUSIONS: Due to the high prevalence of obesity, we should consider both skeletal muscle mass and body fat mass in the diagnosis and treatment of NAFLD. The SF ratio could be a useful index in sarcopenic NAFLD.
RESUMEN
AIMS: The liver function of patients with hepatitis C virus (HCV) infection who obtained sustained virologic response (SVR) has been known to improve after HCV eradication. However, a predictor of liver function after SVR has not been definitively identified. The aim of this retrospective study was to identify a predictor of deteriorated liver function and Fibrosis-4 (FIB-4) index after SVR was achieved by direct-acting antiviral (DAA) treatment. METHODS: This study retrospectively enrolled 248 patients who obtained SVR by DAA treatment. None of the patients developed hepatocellular carcinoma during this study. Liver function was assessed at the end of treatment (EOT) and at 24, 48, 72, and 96 weeks after EOT. RESULTS: At 96 weeks after EOT, the serum aspartate aminotransferase and alanine aminotransferase levels were significantly decreased from those at EOT. The platelet count was significantly increased from 14.9 × 104 /µL at EOT to 17.1 × 104 /µL at 96 weeks after EOT. Ten patients showed an increased FIB-4 (>1.00) index. Multivariate analysis with 171 patients who underwent endoscopic assessment revealed that the presence of varices was an independent predictor of deterioration in the FIB-4 index (odds ratio, 5.56; P = 0.041). CONCLUSION: Most of the study patients who obtained SVR showed improved liver function after EOT. Patients without increasing platelet counts after SVR due to DAA therapy should be evaluated for complications induced by portal hypertension.
RESUMEN
BACKGROUND: The nutritional status of patients with esophageal squamous cell carcinoma (ESCC) harboring dysphagia is often poor. The efficacy and safety of enteral nutrition (EN) versus total parenteral nutrition (TPN) have not been addressed in patients with ESCC requiring nutritional support during definitive chemoradiotherapy (dCRT). METHODS: We performed a retrospective analysis of 51 locally advanced unresectable ESCC patients with dysphagia receiving EN (n = 28) or TPN (n = 23) during dCRT between 2009 and 2016. RESULTS: Patient characteristics in EN vs. TPN were as follows: median age (range), 67 (34 to 82) vs. 66 (57 to 83); ECOG performance status 0/1/2, 11/15/2 vs. 7/14/2; dysphagia score 2/3/4, 11/15/2 vs. 14/8/1; and primary tumor location Ce/Ut/Mt/Lt/Ae, 4/6/14/3/1 vs. 2/2/16/1/2. Median changes in serum albumin level one month after dCRT were +8.8% (-36 to 40) in EN and -12% (-64 to 29) in TPN (P = 0.00377). Weight, body mass index, and skeletal muscle area were not significantly different between the groups. Median durations of hospitalization were 50 days (18 to 72) in EN and 63 days (36 to 164) in TPN (P = 0.00302). Adverse events during dCRT in EN vs. TPN were as follows: catheter-related infection, 0 vs. 6 (27%); aspiration pneumonia, 3 (11%) vs. 2 (9%); mediastinitis, 3 (11%) vs. 1 (5%); grade ≥3 neutropenia, 6 (21%) vs. 14 (64%) (P = 0.00287); and febrile neutropenia, 0 vs. 6 (27%) (P = 0.00561). CONCLUSIONS: EN may be advantageous for improving serum albumin level, and reducing hematological toxicity and duration of hospitalization compared with TPN during dCRT in ESCC patients.

AIM: In Japan, transcatheter arterial chemoembolization (TACE) refractoriness for hepatocellular carcinoma has been defined as an insufficient therapeutic effect after ≥2 procedures. Insufficient TACE for intrahepatic lesions is defined as the presence of > 50% viable lesions (ineffective) or an increase in their number (progressive). This study aimed to examine the possibility of earlier evaluation of TACE refractoriness. METHODS: Patients who underwent TACE for hepatocellular carcinomas > 3 cm in size or with > 3 nodules at our hospital between 2010 and 2014 were analyzed. The cases assessed as TACE insufficient for the first time were divided into 2 groups: the "either" group, evaluated as either "ineffective" or "progressive," and the "both" group, that is, both "ineffective" and "progressive." RESULTS: The study participants included 40 of 212 consecutive patients who underwent TACE, divided into the either (n = 23) and both (n = 17) groups. Seventeen of 23 (73.9%) patients in the either group and all 17 (100%) in the both group had TACE refractoriness (p = 0.0295). CONCLUSIONS: Patients with both "ineffective" and "progressive" lesions are extremely likely to be TACE -refractory at a significantly higher frequency than are those with either condition. Thus, when both of these factors are observed, switching to other therapies should be considered.

Concurrent cisplatin based chemoradiotherapy(CRT)is the standard of care for patients with locoregionally advanced squamous cell carcinoma of the head and neck(LA-SCCHN). Based on the Bonner trial showing the superiority of cetuximab plus radiotherapy to radiotherapy alone, cetuximab based bioradiotherapy(BRT)is considered as an alternative for patients with LA-SCCHN. However, the non-inferiority of BRT compared to CRT has not yet been demonstrated. Furthermore, severe mucositis and dermatitis induced by BRT cannot be neglected. Therefore, the patient's general status and comorbidity should be considered before BRT. Supportive care and patient education are also necessary to safely complete the treatment. Several phase III trials are ongoing to evaluate BRT and CRT for human papillomavirus(HPV)positive oropharyngeal carcinoma. Novel biomarkers are needed for identifying patients most likely to benefit from BRT.

Patients with immunoglobulin (Ig) G4-related sclerosing cholangitis typically have a high serum IgG4 level. However, here we describe our experience of a patient with a normal serum IgG4 level for whom the cholangitis was diagnosed by liver biopsy. A 61-year-old male presented with elevated liver enzymes and a normal serum IgG4 level. The hilar, intrahepatic, and upper extrahepatic bile ducts were stenotic, with no evidence of a pancreatic lesion. We therefore performed a liver biopsy to differentiate between cholangiocarcinoma and primary sclerosing cholangitis. Pathological examination revealed lymphoplasmacytic infiltrates around the bile ducts with a storiform fibrosis. IgG4-positive plasma cells were also observed. These results fulfilled the Japanese diagnostic criteria for IgG4-related sclerosing cholangitis. When this condition is suspected, liver biopsy should be performed even when serum IgG4 levels are normal.

A 77-year-old man presented with epigastralgia. Gastrointestinal endoscopic examination showed advanced gastric cancer, type 3, in the distal antrum. The patient refused surgery and preferred chemotherapy. The regimen consisted of 80 mg/body/day of S-1, continuously administered from day 1-14, followed by discontinuation for 2 weeks. After 2 courses, the patient experienced fatigue and recurrent vomiting. Laboratory studies revealed severe anemia; the hemoglobin level was 5.5 g/dL. An upper gastrointestinal endoscopy revealed pyloric stenosis and significant tumor reduction. Therefore, distal gastrectomy was performed. Histological examination did not reveal any viable cancer cells in the stomach and lymph nodes. Thus, a Grade 3 postchemotherapeutic effect was revealed.

No standard treatment has been established for gastric neuroendocrine carcinoma (G-NEC). We present the case of a patient with recurrent G-NEC who achieved a complete response (CR) with nivolumab. A woman in her 70 s, with no significant medical or family history of illness, underwent an upper gastrointestinal endoscopy, which revealed a Borrmann type 2 tumor in the gastric antrum. Malignant tumor cells were not detected in the endoscopic biopsy samples; however, a malignant gastric tumor was strongly suspected. Therefore, surgical resection was performed, and the tumor was pathologically diagnosed as a G-NEC with liver metastases. Adjuvant etoposide plus carboplatin was administered for four cycles, but recurrence in the liver was observed 5 months after the completion of adjuvant chemotherapy. Ramucirumab plus paclitaxel and irinotecan were introduced as second and third-line treatments. After these treatments, the mesenteric lymph node metastases expanded. Tumor mutation burden (TMB) was low (five mutations/megabase), and microsatellite instability remained stable. However, programmed death-ligand 1 Combined Positive Score (CPS) was ≥ 5 in the resected sample. Therefore, nivolumab monotherapy was introduced as a fourth-line treatment. The mesenteric lymph node metastases exhibited swelling 3 weeks after the initiation of nivolumab; however, they rapidly shrank, and CR was later achieved. Treatment with nivolumab is currently ongoing for 12 months. This is the first report of nivolumab monotherapy in a patient with G-NEC who showed pseudo-progression. Even in TMB-low and microsatellite stable cases, nivolumab may be a viable option for patients with G-NEC.
RESUMEN
BACKGROUND: Data regarding treatment sequence for vulnerable patients with metastatic colorectal cancer (mCRC) in a real-world setting are lacking. OBJECTIVE: We aimed to assess treatment outcomes in second-line or later chemotherapy for vulnerable patients with mCRC in a real-world setting. PATIENTS AND METHODS: Vulnerable patients with mCRC who received less intensive treatment ('vulnerable') regimens, i.e. fluoropyrimidines with or without biologics (FP), reduced-dose doublet regimens with or without biologics (Doublet), and anti-epidermal growth factor receptor monotherapy (Anti-EGFR), as first-line therapy between June 2015 and December 2018 were retrospectively reviewed. RESULTS: A total of 210 patients from 15 hospitals were analyzed. The median age was 78 years (range 28-90), and 44 patients (21%) had an Eastern Cooperative Oncology Group performance status (ECOG PS) score of 2. In the entire population, the median time to treatment failure (TTF) and overall survival (OS) were 7.6 and 21.4 months, respectively. Following the failure of first-line therapy in 195 patients, 74 (38%), 24 (12%), and 13 (7%) patients received vulnerable regimens, full-dose doublet regimens with or without biologics, and other regimens, respectively, whereas 84 (43%) received best supportive care (BSC). In patients receiving vulnerable regimens as second-line therapy, the median TTF and OS were 4.4 and 13.7 months, respectively, while response rate and disease control rate were 18% and 62%, respectively. In 84 patients who received BSC, the median OS was 3.5 months. CONCLUSIONS: Second-line chemotherapy for vulnerable patients with mCRC showed clinically meaningful outcomes; however, few patients received second-line therapy, and survival among patients who received BSC was dismal.

Trifluridine/tipiracil (FTD/TPI) is an oral anticancer agent used as a third- or later-line treatment for patients with metastatic gastric cancer/gastroesophageal junction cancer (mGC/GEJC). The C-reactive protein-to-serum albumin ratio (CAR) is an inflammation-based prognostic marker in gastric cancer. This retrospective study evaluated CAR's clinical significance as a prognostic factor in 64 patients with mGC/GEJC administered FTD/TPI as a third- or later-line therapy. Patients were categorized into high- and low-CAR groups based on pre-treatment blood data. This study evaluated associations between CAR and overall survival (OS), progression-free survival (PFS), clinicopathological features, treatment efficacy, and adverse events. The high-CAR group had significantly worse Eastern Cooperative Oncology Group performance status, a higher prevalence of patients administered with a single course of FTD/TPI, and a higher rate of patients not administered chemotherapy after FTD/TPI therapy than the low-CAR group. Median OS and PFS were significantly poorer in the high-CAR group than in the low-CAR group (113 vs. 399 days; p < 0.001 and 39 vs. 112 days; p < 0.001, respectively). In multivariate analysis, high CAR was an independent prognostic factor for OS and PFS. The overall response rate was not significantly different between the high- and low-CAR groups. Regarding adverse events, the high-CAR group had a significantly lower incidence of neutropenia and a higher incidence of fatigue than the low-CAR group. Therefore, CAR may be a potentially useful prognostic factor for patients with mGC/GEJC treated with FTD/TPI as third- or later-line chemotherapy.
RESUMEN
BACKGROUND/AIM: Trifluridine/tipiracil (FTD/TPI) is an anticancer-agent that is administered as third-line or later chemotherapy for metastatic gastric/gastroesophageal junction cancer (mGC/GEJC). Although inflammatory and nutritional statuses have attracted attention as prognostic factors for patients with mGC/GEJC in this therapy, their usefulness has not been fully clarified. Thus, this study investigated the clinical significance of prognostic nutritional index (PNI), neutrophil/lymphocyte ratio (NLR), and NLR/serum albumin (Alb) ratio in patients administered FTD/TPI. PATIENTS AND METHODS: This retrospective study included 64 patients who underwent FTD/TPI treatment for mGC/GEJC at Kanagawa Cancer Center, Kanagawa, Japan, between October 2019 and June 2022. Patients were divided into high and low PNI, NLR, and NLR/Alb groups according to their pretreatment blood data. This study evaluated the associations between the inflammatory and nutritional indexes and survivals. RESULTS: Overall survival (OS) and progression-free survival (PFS) of patients with low PNI were significantly poorer than those with high PNI. However, low PNI was not an independent prognostic factor for OS and PFS. There was no significant association between NLR and OS or PFS. In contrast, the OS of patients with high NLR/Alb was significantly poorer than those with high PNI and low NLR/Alb. Furthermore, multivariate analysis showed that high NLR/Alb was an independent prognostic factor for OS. CONCLUSION: The NLR/Alb may be a useful prognostic factor in patients with mGC/GEJC being administered FTD/TPI as third-line or later chemotherapy.

BACKGROUND/AIM: Irinotecan and trifluridine/tipiracil (FTD/TPI) are fourth-line treatment options after third-line nivolumab for advanced gastric cancer (AGC). However, the efficacy and safety of irinotecan and FTD/TPI in the fourth-line setting after third-line nivolumab remains unclear. This study aimed to evaluate the efficacy and safety of irinotecan and FTD/TPI in the fourth-line setting after third-line nivolumab. PATIENTS AND METHODS: We identified 137 AGC patients treated with nivolumab as third-line treatment in our institute between October 2017 and July 2021. Of these, we recruited 19 AGC patients who initiated irinotecan and 23 AGC patients who initiated FTD/TPI in the fourth-line setting until September 2021. RESULTS: The median overall survival was 5.83 months for irinotecan and 6.31 months for FTD/TPI. Median time-to-treatment failure was 2.07 months for irinotecan and 1.64 months for FTD/TPI. While the frequency of all-grade diarrhea was higher in irinotecan (36% vs. 17%), grade ≥3 neutropenia tended to be higher in FTD/TPI (21% vs. 35%). CONCLUSION: Irinotecan and FTD/TPI may be clinically useful as fourth-line treatments after nivolumab.

For an esophageal submucosal mass suspicious of granular cell tumor (GCT) based on gross appearance and endoscopic ultrasound findings, a sufficient number of biopsy specimens is required for a definite diagnosis using immunohistochemical examination. When the specimen obtained by forceps biopsy is insufficient, endoscopic ultrasound-fine needle aspiration (EUS-FNA) is believed to be an useful alternative. However, it may be difficult to obtain an adequate amount of tumor material using EUS-FNA. Mucosal incision-assisted biopsy (MIAB) is a simple method that can collect larger amounts of specimens. This procedure is helpful for physicians who encounter the problem of obtaining an adequate amount of biopsy material from esophageal tumors suspicious for GCT. We present a case of esophageal GCT that was successfully diagnosed through MIAB.

Introduction: Duodenal neuroendocrine tumors (DNETs) smaller than 1 cm in diameter, without invasion to the muscularis propria, have a low risk of metastasis. Therefore, DNETs are frequently resected endoscopically. However, among the various procedures, the best fit for DNET in terms of feasibility, effectiveness, and simplicity is unclear. Methods: Patients with DNET who underwent endoscopic submucosal resection using a ligation device (ESMR-L) at Kanagawa Cancer Center between May 2003 and December 2020 were studied retrospectively to evaluate clinical characteristics and short-term and long-term outcomes. Results: Eleven consecutive patients with 12 lesions were treated with 12 sessions of ESMR-L. Lesions were discovered in patients at a median age of 68 (range, 50-83) years. One patient had two lesions at the time of the initial ESMR-L session. Eleven of the 12 lesions (91.7%) existed in the duodenal bulb, of which 10 (83.3%) were in the anterior wall, and the remaining one (8.3%) existed in the descending part of the duodenum. The en bloc and R0 resection rates were 100% and 75%, respectively. The rates of bleeding and perforation were both 0%. Among the four patients who had non-curative resections, two patients underwent additional surgery after ESMR-L. One patient had a local remnant tumor, and the other had lymph node metastasis. In cases of local remnant tumors, the vertical margin was positive in the ESMR-L specimen. In that case, ligation by the O-ring was insufficient, retrospectively. All patients had no recurrence during the median follow-up period of 5.7 years. Discussion: ESMR-L was the best fit for DNET within the indications for endoscopic resection. It is a simple procedure that enables easy and complete resection of DNETs without complications.
RESUMEN
Heterotopic gastric gland (HGG)-originating early gastric cancer was endoscopically resected. We resected the HGG, widely marked the perimeter outside the submucosal tumor-like area, injected from outside the markings into the submucosa, dissected the muscular layer, and used fine-tip hood. HGG removal and ensuring negative horizontal and vertical margins are critical.
