SURVIVAL DATA AFTER TACE IN PATIENTS WITH HEPATOCELLULAR CARCINOMA (HCC) IN 2010: IMPACT ON CLINICAL PRACTICE AND RESEARCH

OBJECTIVES - Evaluate the survival of HCC patients treated with TACE- DEB following a strict selection (preserved liver function, absence of cancer related symptoms, extrahepatic spread or vascular invasion) - Evaluate causes of untreatable progression (UTP)

PATIENTS AND METHOD HCC patients treated by TACE-DEB between February 2004 and March 2010 Retrospective review of: - baseline characteristics - development of treatment related adverse events - overall survival

RESULTS - 97 patients evaluated - Median follow up 24.4 months ( ) - At the time of evaluation 31 patients had died 2 received transplantation 22 had received Sorafenib because of progression not amenable for TACE

1.Current survival of non-ressectable HCC patients within stages A and B is 47,7 months 2.Current survival of BCLC B patients is 40,2 months 3.These new data update the previous survival results obtained from Lipiodol-TACE, which impacts in clinical practice and research purposes CONCLUSIONS
