trial of s-1 in combination with sorafenib for patients with advanced hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma

Summary: in preclinical studies, 5-fluorouracil, one of the active metabolites of s-1, showed synergistic effect to sorafenib in human colon carcinoma cell lines. therefore, sorafenib combined with s-1 might be more effective treatment for patients with advanced hcc than sorafenib monotherapy. the investigators propose to conduct a phase i study to determine maximal tolerated dose (mtd) of s-1 in combination with fixed dose of sorafenib in patients with advanced hcc
