A new chemotherapeutic regimen for advanced unresectable hepatocellular carcinoma

The aim of this study was to evaluate the efficacy and toxicity of a novel chemotherapeutic regimen for advanced unresectable hepatocellular carcinoma.

Seventeen patients with unresectable hepatocellular carcinoma were treated by arterial infusion once a week of low-dose cisplatin (12 mg/m2) and doxorubicin (6 mg/m2) via a subcutaneously implanted injection port and by daily oral administration of 300 mg/day of UFT comprising 5-fluorouracil prodrug tegafur (FT) and uracil (U) at a ratio of 1:4.

The median number of chemotherapy courses was 13 (range, 5-33). All patients were evaluated for response, toxicity, and survival. As assessed by conventional imaging criteria, there were 3 (17.6%) complete responses with disappearance of the primary tumor, tumor thrombosis of the portal vein and metastatic para-aortic lymph node swelling. In addition, there were 4 (23.5%) partial responses. Among 11 patients who had initially high alpha-fetoprotein levels (> 200 ng/mL), 5 (45%) had a > 50% drop after therapy. The overall tumor response rate (complete response + partial response) was 41% and the median survival was 7.1 (range; 4.2-25.1) months. As for toxicity, there was 1 treatment-related death due to septicemia caused by catheter-related infection. Myelosuppression and renal toxicity was relatively mild and transient.

These results suggest that our low-dose chemotherapeutic regimen may be useful for the treatment of advanced unresectable hepatocellular carcinoma without worsening the quality of life of the patient.
