Abstract
We performed percutaneous microwave coagulation therapy (PMCT) on 89 patients (86 patients with hepatocellular carcinoma, 1 patient with liver metastasis from gastric cancer, 1 patient with liver metastasis from gastric schwannoma, 1 patient with both hepatocellular carcinoma and liver metastasis from colon cancer). CT was performed after PMCT to evaluated the efficacy in all cases. In 78 cases, complete necrosis of the lesions with some safety margin was achieved. In the other 11 cases, PMCT was used only palliatively, but the goal of mass reduction was accomplished. Encountered complications were pleural effusion, hemobilia, subcapsular hematoma, hemoperitoneum, biloma, and others. In conclusion, although PMCT is useful in the treatment of small or middle-size liver tumors, there are various problems to be solved. Improvement of the machine and others is mandatory.
