Treatment of hepatocellular carcinoma (HCC) after sorafenib (S) over the last 10 years.

438Background: Until recently there were no standard treatments for HCC patients after S. This study characterizes subsequent treatments (STx) received by HCC patients over the past 10 years and assesses their impact on survival. Methods: HCC patients treated with S between 01/2008 – 06/2017 in British Columbia, Alberta, and two cancer centers in Toronto, Ontario, Canada (Princess Margaret and Sunnybrook Cancer Centre) were included. Clinical, pathologic, laboratory, treatment, and outcome data were collected. The Kaplan-Meier method was used to assess overall survival (OS) based on STx, and stratified according to a better prognostic group (BPG), defined as ECOG 0-1 and CP-A, and worse prognostic group (WPG), defined as ECOG≥2 or CP-B/C. Results: A total of 730 patients were identified. 177 (24.2%) received STx (table). Patients who received STx had longer median OS (mOS) than those who had no further treatment (12.1 vs. 3.3 months; p < 0.001). For patients treated with localized, systemic, or palliative...
