Gemcitabine plus oxaliplatin for patients with advanced hepatocellular carcinoma using two different schedules.
BACKGROUND
New therapies are needed to improve the prognosis of patients with advanced hepatocellular carcinoma (HCC). Various gemcitabine-oxaliplatin combinations have been tested recently in patients with ovarian and pancreatic carcinoma, yielding interesting results with little toxicity. Therefore, the authors evaluated the activity and toxicity of two such combinations in patients with HCC.


METHODS
Twenty-one patients were enrolled prospectively in the study. Eleven patients received gemcitabine 1000 mg/m2 on Day 1 and oxaliplatin 100 mg/m2 on Day 2 (GEMOX-1), and 10 patients received gemcitabine 1500 mg/m2 on Day 1 followed by oxaliplatin 85 mg/m2 on Day 1 (GEMOX-2). Treatment was repeated every 2 weeks until disease progression developed or until unacceptable adverse effects occurred.


RESULTS
All patients were assessable for response and toxicity. Four patients (19%) achieved objective responses (95% confidence interval, 13-26%), including 3 patients in the GEMOX-1 group and 1 patient in the GEMOX-2 group. Ten patients (48%) had stable disease, and 7 patients (33%) experienced disease progression. The median progression-free survival was 5 months, and the median overall survival was 12 months. Fifty-four percent of patients in the GEMOX-1 group and 50% of patients in the GEMOX-2 group had received previous systemic chemotherapy or cisplatin-based chemoembolization. Grade 3-4 hematologic toxicity, according to National Cancer Institute Common Toxicity Criteria, consisted of thrombocytopenia (GEMOX-1 vs. GEMOX-2, 18% vs. 40%) and neutropenia (0% vs. 30%). No Grade 3-4 nonhematologic toxicity was observed, except for 1 episode of Grade 3 diarrhea. Grade 1 neurotoxicity and Grade 2 neurotoxicity (specific scale), respectively, were observed in 4 patients and 7 patients receiving GEMOX-1 and in 7 patients and 1 patient receiving GEMOX-2.


CONCLUSIONS
Gemcitabine-oxaliplatin combination therapy is feasible in patients with advanced HCC. The GEMOX-1 regimen was tolerated better than the GEMOX-2 regimen. Currently, the GEMOX-1 regimen is being evaluated in a Phase II study in previously untreated patients with HCC.
