In 39 patients with hepatocellural carcinoma (52 nodules) treated by percutaneous microwave coagulation therapy (PMCT), modality of recurrence was compared with regard to tumor size and treatments, to find the improvement of PMCT electrodes. Local recurrence occured in 4 (12%) of 35 patients with less than 30mm in diameter and less than 3 nodules, and in 2 (50%) of 4 patients with more than 31 mm in diameter.In patients with less than 30 mm in diameter and less than 3 nodules, except for these 4 patients with recurrence, there is no difference at tha ratio of recurrence between patients treated by PMCT and hepatectomy.To solve the recurrence at surgical margin is necessary for the enough diameter of tissue coagulation with a single insertion to be grown larger, and to be stronger and longer electrode.If these problems are conquested, the indications for PMCT will be developed for the tumors with more than 31 mm in diameter.
