Both treatments were generally well-tolerated. Clinically significant AEs were observed in 35.1% of patients in the GC arm and 29.9% in the GS arm.Conclusions: GS, which does not require hydration, should be considered a new, convenient standard of care option for patients with advanced/recurrent BTC.Clinical Trial number: This trial has been registered with the UMIN Clinical Trials Registry (http://www.umin.ac.jp/ctr/index. htm), number UMIN000010667.

BackgroundEpithelioid hemangioendothelioma is an exceedingly rare sarcoma often occurring as an indolent angiocentric vascular tumor at various anatomic sites. Few reports have evaluated large case series of epithelioid hemangioendothelioma.MethodsWe conducted a retrospective analysis of the clinical data of 42 consecutive patients with epithelioid hemangioendothelioma who were pathologically diagnosed between 1990 and 2014 at 13 Japanese tertiary hospitals. We analyzed their clinical characteristics, tumor features and prognostic factors.ResultsThe study included 22 men and 20 women, with a median age of 54 (range, 18–78) years. Pain was the most common symptom, occurring in 15 (68%) of the 22 symptomatic patients. The median maximum tumor diameter was 4.0 (range, 1.0–12.8) cm. The most commonly involved organs were the liver (81%), lungs (57%), and bones (12%). The overall survival rates were 79.5% at 1 year and 72.0% at 5 years. Substantially better survival was observed in asymptomatic patients than in symptomatic patients (P = 0.03), and better survival was also ovserved in patients with Ki-67 index ≤10% than in those with Ki-67 index > 10% (P = 0.04). By multivariate analysis, tumor size > 3.0 cm was associated with decreased survival (P = 0.049, hazard ratio 13.33).ConclusionsThis study showed the clinical characteristics of Japanese patients with epithelioid hemangioendothelioma. Tumor size > 3.0 cm is an independent indicator of a poor prognosis in epithelioid hemangioendothelioma. The presence of symptoms at the time of diagnosis and high Ki-67 index implied poor survival.

This randomized clinical trial assesses whether etoposide plus cisplatin or irinotecan plus cisplatin is a more effective treatment regimen in terms of overall survival in patients with advanced neuroendocrine carcinoma of the digestive system.

Objectives The aim of this multicenter retrospective study was to identify the optimal chemotherapeutic regimen for advanced pancreatic acinar cell carcinoma (PACC). Methods Fifty-eight patients with histopathologically confirmed advanced PACC who had received chemotherapy between 1996 and 2013 were enrolled. The clinical characteristics of the patients and the treatment efficacy data were collected from the medical records at 16 Japanese institutions, using standardized data collection instrument. Results The most commonly selected treatment regimens were gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens. The overall response rate in the patients who received first-line chemotherapy were 7% and 38%, respectively, and the median overall survival was 13.2 months. When the data for all the treatment lines were aggregated, the response rates to gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens were 7%, 18%, 40%, and 29%, respectively. The overall survival tended to be better in patients who had received a platinum-containing regimen (hazard ratio, 0.50; 95% confidence interval, 0.23–1.11; P = 0.08) or irinotecan-containing regimen (hazard ratio, 0.42; 95% confidence interval, 0.15–1.19; P = 0.09) at least once in the treatment course as compared with those who had not. Conclusions Our findings suggested that platinum- and irinotecan-containing regimens exhibited some potential efficacy in patients with advanced PACC.

Background: Platinum-containing regimens are widely used as first-line chemotherapy for unresectable pancreatic neuroendocrine carcinoma (NEC), but second-line chemotherapies have yet to be established. Objectives: We evaluated the safety and efficacy of everolimus in patients with pancreatic NEC refractory or intolerant to platinum-containing chemotherapy. Methods: This study was a prospective, multicenter, phase II trial in patients with pancreatic NEC after platinum-containing chemotherapy. Everolimus treatment was continued until disease progression or intolerable toxicity was observed. The primary endpoint was progression-free survival (PFS). Results: Participants comprised 25 patients. Median age was 63 years, median PFS was 1.2 months (95% confidence interval [CI] 0.9-3.1 months), median overall survival was 7.5 months (95% CI 3.1-13.5 months), overall response rate was 0%, and disease control This article is licensed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND) (http://www.karger.com/Services/OpenAccessLicense).
