Abstract

Percutaneous microwave coagulation therapy (PMCT) was performed on 31 patients with hepatocellular carcinoma (HCC) smaller than 3 cm in diameter (average 2 cm). According to Child classification, 14 patients were in the Child grade A, 15 in the Child grade B, and 2 in the Child grade C. The 1-, 2- year survival rates were 100%, 88%. Local recurrences in the advanced nodules were more often observed than in the early nodules. Major complications of the treatment were peritoneal bleeding in two patients and subcapsular liver hemorrhage in one patient. PMCT seems to be a valuable percutaneous local treatment for small HCC.
