    Abstract:
    Surgery for advanced hepatocellular carcinomas (HCCs) has not been standardized. We report on a long-term tumor-free survivor who underwent extensive microwave coagulation therapy (MCT) for multiple bilobar HCCs. A 61 year-old woman was diagnosed to have bilobar HCCs, including a large tumor, 9 cm in diameter, and 4 small satellite nodules, associated with chronic hepatitis B. The patient had received repeated chemoembolizations using iodized oil, but the increased alpha-fetoprotein level did not fall to normal. The main tumor was unresectable because the tumor involved the caval vein and hepatic veins. The patient underwent extensive MCT with a total of 134 electrode insertions. The paracaval portion of the main tumor was meticulously coagulated under sonographic guidance to avoid vascular injury. The post-operative course was uneventful. Post-operative computed tomography (CT) showed complete necrosis of all tumors. The patient is alive without tumor recurrence for 4 years after MCT. This case proves that extensive MCT can provide a chance of cure in selected patients with multiple bilobar HCCs and centrally located HCCs near the caval vein.
