Patient healthcare trajectories of intrahepatic cholangiocarcinoma in France: A nationwide retrospective analysis

Abstract : BACKGROUND: Little is known about the epidemiology and patterns of care of intrahepatic cholangiocarcinoma (iCCA) in daily clinical practice. The aims of this study were to estimate the number of declared cases during the study period 2014-2015 in France from a hospitalization database and to describe the healthcare trajectories of these patients. METHODS: A retrospective analysis was carried out using the French nationwide prospective hospitalization database. All pts with a new diagnosis of "carcinoma of the intrahepatic bile duct" who had a first hospital stay in the Medicine, Surgery and Obstetrics departments (MSO) between 2014 and 2015 with a 2-year follow-up were included. Data related to the first identified stay (S1) in the MSO and on all subsequent stays in the MSO, aftercare and rehabilitation or home hospitalization were analysed. FINDINGS: A total of 3650 new iCCA cases were identified. At S1 (admission via emergency room (ER) in 28%), the median age of the patients was 73 years, 57% were male and 35% had metastases. Jaundice/anaemia/ascites/cholangitis were reported in 17%/16%/12%/7% of patients, respectively. The care of patients at S1 was mainly provided in general hospitals (CHG, 60%). A total of 896 (24%) patients died during S1. They were more frequently hospitalized via the ER (48% vs 23%), metastatic (52% vs 35%) and symptomatic. Subsequent stays were identified for 2507 (69%) patients. Three healthcare pathways were defined: surgery (n = 519; 14%), chemotherapy (CT) without surgery (n = 812; 22%) and best supportive care (BSC) (n = 2319; 63%). CT, surgery and BSC were most frequently performed in the cancer centres, university hospitals and CHG, respectively. INTERPRETATION: This medico administrative study reveals a higher number of iCCA cases than that previously reported by registries and highlights the severity of this disease. FUNDING: This study was sponsored by Incyte Biosciences International Sàrl., Geneva, Switzerland. INCYTE validated the design of the study, the analysis, the interpretation of data and the writing of the manuscript which was first written by the 2 experts and CEMKA.
