Low-dose cisplatin plus oral tegafur and uracil for the treatment of lung metastases of hepatocellular carcinoma.

Background/aims: An effective treatment for unresectable multiple lung metastases of hepatocellular carcinoma have never been established.

Methodology: Six patients received the chemotherapy described herein as an initial treatment for lung metastases of hepatocellular carcinoma. Low-dose cisplatin infusion plus oral tegafur and uracil administration combination therapy essentially consisted of cisplatin (10 mg/day over 1 hour) infused on days 1-5 every week and oral tegafur and uracil (300 mg/day) administrated every day. This treatment was repeated weekly for essentially 4 consecutive weeks.

Results: Complete response was observed in no cases and partial response in 3 cases, while no change was observed in 4 cases and progressive disease in one case. An overall response rate was 50%. The serum alpha-fetoprotein and des-Y-carboxyprothrombin were reduced in most of the patients. Leukopenia of grade 2 was observed in only 1 (17%) patient. Thrombocytopenia of grade 2 was observed in 2 (33%) patients. Nausea (up to Grade 2) was occurring in 4 (67%) patients. Three patients with no other distant metastasis survive more than two years after lung metastasis, and the quality of life of these patients are well preserved.

Conclusions: Low-dose cisplatin infusion combined with oral tegafur and uracil administration for the treatment of lung metastases of hepatocellular carcinoma may be an effective regimen with a high response rate and acceptable toxicities, although a larger study will be necessary to confirm the efficacy.
