We treated 20 patients with hepatocellular carcinoma or metastatic liver cancer by microwave coagulation. Microwave tissue coagulation therapy (MCT) was performed via percutaneous route (PMCT) or laparoscopic guidance (LMCT). These approaches were chosen according to tumor location and the degree of hepatic reserve. MCT was completed in all patients in present series without complications. Tumor necrosis, including the surrounding liver tissue, was confirmed by a dynamic CT scan taken one month to three months after MCT, showing no enhancement of the low-density area. LMCT or PMCT can be a promising therapeutic modality as a new option of local treatment because of negligible intraoperative blood loss, no significant postoperative complication and rapid return of patients to their preopertive activities.
