RESUMO
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.

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.
RESUMO
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.

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.
RESUMO
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.

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.
