État des lieux des pratiques de prise en charge des cancers des voies biliaires en France : résultats de l'enquête nationale ACABi

Abstract

Overview of biliary tract cancer management practices in France: results of the ACABi national survey INTRODUCTION: Biliary tract cancers (BTC) are rare. Their management has evolved in recent years. ACABi conducted a survey on the management practices of CVB in France. METHODS: A questionnaire was developed by a multidisciplinary team and distributed (June-July 2021) by the French digestive oncology societies. The data were analyzed according to the type of practice center (group A: university hospital or cancer comprehensive center, group B: general hospital or private hospital) RESULTS: 172 physicians (hepato-gastroenterologists: 58.0%, oncologists: 19.5% and surgeons: 18.3%), representing all French regions, responded. Access to echo-endoscopy and endoscopic retrograde cholangio-pancreatography was identical between the groups (> 80%), unlike cholangioscopy (group A: 82.9%, group B: 63.6%). In the adjuvant setting, capecitabine was proposed in the majority (> 65%). For non-operable tumors, the most commonly used first-line chemotherapy was cisplatin/gemcitabine (CISGEM, 66.3%). In 38.5% of cases, it was not performed in the day hospital and only 13.6% proposed a break after a fixed number of courses. The most commonly used second-line treatment was 5FU/oxaliplatin (FOLFOX, 52.3%). Molecular profiling was performed in more than half of the patients for 41.1% of respondents in group A and 18.8% in group B. DISCUSSION: This survey shows the application of therapeutic standards but also certain practices diverging from the recommendations as well as disparities between centers.
