Role of liver-directed local tumor therapy in the management of hepatocellular carcinoma with extrahepatic metastases: a SEER database analysis.


PMID 27830958

Abstract

This study assessed the prognostic impact of the liver-directed local tumor therapy in the management of hepatocellular carcinoma (HCC) with extrahepatic metastases. Metastatic HCC patients diagnosed between 2004 and 2013 were identified from the SEER (Surveillance, Epidemiology, and End Results) database. Propensity-matched analysis was performed considering baseline characteristics (age, gender, race, histology, TNM stage, site of metastases, fibrosis score and alpha fetoprotein). A total of 2529 patients were identified. The median age was 65 years, and 151 patients received liver-directed local treatment (either surgical treatment or local destructive treatment). Both before and after propensity score matching, cancer-specific and overall survival (p < 0.0001 for all) were better in the liver-directed local therapy group. When the overall survival was stratified by the type of local treatment (surgical resection versus destructive treatment), both types of treatment improved overall survival (p < 0.0001 for both). In multivariate analysis of the matched population, the only factor correlated with better survival receiving is local therapy (p < 0.0001). This analysis suggests that liver-directed local treatment may play a role -in addition to systemic treatment- in the management of selected patients with metastatic HCC. Further prospective randomized controlled trials are needed to confirm or deny this hypothesis.
