Trends in Epidemiology, Treatment, and Survival of Hepatocellular Carcinoma Patients Between 1998 and 2009

description

The aim of this study was to analyze clinical presentation, course of disease, and management of patients with hepatocellular carcinoma (HCC) in a German referral center between 1998 and 2009.HCC is a rare tumor in Germany, but its incidence has increased over the last 30 years. New therapies such as chemoembolization with drug-eluting beads, selective internal radiotherapy, and sorafenib were introduced recently; however, the impact on clinical management and overall survival (OS) is unclear.In this retrospective analysis, 1066 patients with HCC, separated into two 6-year periods (n=385; 1998 to 2003 and n=681; 2004 to 2009) were evaluated.The number of patients presenting each year (64 vs. 114 per year), with an age over 80 years or with nonalcoholic steatohepatitis increased significantly between periods. The main risk factors were alcoholic liver disease in 51.7%, chronic hepatitis C virus in 28.2%, and chronic hepatitis B virus in 13.4% of patients with liver cirrhosis and HCC. Patients presented with more advanced tumor stages and with worse liver function in period 2. The majority (61.6%) of patients received local treatment over a spectrum of Barcelona Clinic Liver-Cancer (BCLC) stages, whereas systemic therapy was offered to a minority (8.8%) and limited to BCLC stage C patients only. OS decreased in BCLC stage A and D and improved in BCLC stage B and C and decreased for all patients from 16.5 to 15.3 months between periods.No improvement of OS was observed when comparing time periods, partly because of the more advanced stage of HCC and because of the increasing age in the second time period. Improved and new therapeutic options and the intensification of surveillance programs are likely to increase survival of HCC patients in the future.
