Sorafenib versus cytotoxic chemotherapy for patients with advanced hepatocellular carcinoma: a retrospective, single-institution study.

BACKGROUND: Prior to the 2008 advent of sorafenib, traditional cytotoxic agents were the therapeutic mainstay for patients with advanced hepatocellular carcinoma (HCC). We thus undertook a clinical study of sorafinib and conventional cytotoxic therapy for HCC, comparing efficacy and safety.

METHODS: From January, 2002 to December, 2009, 173 patients with unresectable HCC were reviewed retrospectively. Among them, 44 (25.4%) had been treated with sorafenib, and the remainder had received cytotoxic therapy (CTX). We evaluated objective response rate (ORR), progression free survival (PFS), overall survival (OS), and toxicity profiles.

RESULTS: Median OS of sorafinib was 23.0 weeks (95% CI, 8.1-37.9) vs 43.6 weeks (95% CI, 34.0-53.2) for CTX. Likewise, median PFS was 11.1 weeks (95% CI, 6.5-15.8) vs 12.4 weeks (95% CI, 8.1-16.7) for sorafenib and CTX, respectively. Neither parameter differed significantly (OS, p = 0.105; PFS, p = 0.496). ORR and disease control rate for sorafenib were 2.3% and 52.3% vs 6.2% and 43.4% for CTX. CTX-treated patients experienced more Grade 3/4 neutropenia (19.7% vs 0% for sorafenib), while sorafenib therapy was more often linked to dermatologic toxicities (all grades), such as hand-foot skin reaction, rash, and pruritus.

CONCLUSION: Although sorafenib has become the treatment of choice for advanced HCC, there are still unsettled issues regarding the optimal use of sorafenib. Our analysis indicates that conventional CTX can be another option of treatment for advanced HCC. To improve clinical outcomes, further prospective investigations which define the role of CTX are needed.
