Gemcitabine Plus Carboplatin in Patients with Advanced Hepatocellular Carcinoma: Results of a Phase II Study

Abstract

Objectives . Assessment of gemcitabine/carboplatin combination in patients with advanced-stage hepatocellular carcinoma (HCC) in a phase II trial for safety and efficacy. Methods . Forty patients with previously untreated advanced-stage HCC were prospectively enrolled and subjected to gemcitabine/carboplatin regimen which consisted of gemcitabine 1000 mg/m 2 on days 1 and 8, and carboplatin AUC 6 on day 1. The treatment was repeated every 3 weeks until disease progression or limiting toxicity. Results . Forty patients were assessable for efficacy and toxicity. In all, 276 treatment cycles were administered. No toxic deaths occurred. Hematological grade 3-4 toxicity consisted of thrombocytopenia (27% of patients) and neutropenia (24%), including 2 febrile neutropenia and anemia (9%). Grade 3 carboplatin-induced neurotoxicity was observed in 3 (9%) patients. ORR was 23% (95% CI, 0.10–0.29) with 9 partial responses and disease stabilization was observed in 46% (95% CI, 0.22–0.42) of patients, giving a disease control rate of 69%. Median progression-free and overall survival times were, respectively, 5 months (95% CI: 3–8 months) and 8 months (95% CI: 6–18 months). Conclusion . The gemcitabine/carboplatin regimen seems to be effective, well tolerated, and active in advanced HCC.
