e16624 Background: Little is known about epidemiology and patterns of care of iCCA in daily clinical practice. The aims of this study were to estimate from real-life data the incidence of iCCA in France and to describe the healthcare pathways of these patients (pts). Methods: A retrospective analysis was carried out using the nationwide prospective French PMSI database. All pts with a new diagnosis of "carcinoma of the intrahepatic bile duct" who had a 1st hospital stay in Medicine, Surgery and Obstetrics departments (MSO) between 2014 and 2015 with a 2-year follow-up were included. Data related to the 1st identified stay (S1) in MSO and on all subsequent stays in MSO, Aftercare and Rehabilitation (SSR) or Home Hospitalizations (HAD) were analyzed. Results: A total of 3,650 new iCCA cases were identified. At S1 (admission via emergency room [ER] in 28%), median age of pts was 73y, 57% were male and 35% had metastases. Jaundice/anemia/ascites/cholangitis were reported in 17%/16%/12%/7%, respectively. Pts care at S1 was mainly provided in general hospitals (CHG, 60%), rather than university hospitals (CHU, 15%), private (20%) or cancer centers (CLCC, 6%). 896 (24%) pts died during S1: they were more frequently hospitalized via ER (48% vs 23%), metastatic (52% vs 35%) and symptomatic. Subsequent stays were identified for 2,507 pts (69%). Similarly to S1, most pts were managed in CHG during their follow-up (70% vs 20% in CHU and 12% in CLCC). Based on the number of pts treated over the study period, centers were classified as low (≤5 pts, 68%), intermediate (5-20 pts, 26%) and high volume ( > 20 pts, 6%). 47% of the high-volume centers were CHU/CLCC. Three healthcare pathways were defined: surgery (n = 519; 14%), chemotherapy (CT) without surgery (n = 812; 22%) and best supportive care (BSC) (n = 2,319; 63%). CT, surgery and BSC were most frequently performed in CLCC, CHU and CHG, respectively. Pts who received CT (mean time between S1 and start of CT: 1.9 months) were younger, less frequently hospitalized via ER and less symptomatic at S1. A palliative care code was associated with S1 in 25% of pts and with a subsequent MSO/SSR/HAD stay in 60%. Conclusions: This real-life, medico-administrative study, covering all hospitalized patients in France, reveals a higher incidence of iCCA than that previously reported by cancer registries. It also highlights the severity of this disease, the central role of CHG in the management of pts and the expertise of CHU and CLCC for surgery and CT, respectively.
