Abstract: | The majority of patients with hepatocellular carcinoma will develop either unresectable or metastatic disease and, therefore, are candidates for systemic chemotherapy. Only a few chemotherapeutic agents have shown documented activity in the treatment of advanced hepatocellular carcinoma and there is clearly a need for the evaluation of new active drugs. Therefore, we performed a phase I trial with a weekly schedule of paclitaxel in patients with advanced hepatocellular carcinoma. 16 patients with documented progression of unresectable hepatocellular carcinoma were included. After premedication, paclitaxel was given as a 1 h infusion on days 1, 8, 15, 22, 29 and 36 representing one treatment cycle. The cycle was repeated every 50 days. The starting dose was 70 mg/m2 and the doses were escalated in steps of 10 mg/m2/week. A minimum of 3 patients were treated at each dose level. All treatment was given on an out-patient basis. Dose-limiting toxicity was reached at a dose of 100 mg/m2/week with 2 of 6 patients treated at that dose level having WHO grade 4 neutropenia. Other toxic side-effects were only mild. 1 partial response and 9 cases with disease stabilisation were observed in 16 patients with initially progressive disease. We, therefore, conclude that the recommended dose for a further phase II trial in patients with hepatocellular carcinoma is 90 mg/m2/week. These data indicate that paclitaxel given at this dose and schedule might have activity in hepatocellular carcinoma and further investigation in phase II trials is warranted. |
