[Surgical treatment of advanced hepatocellular carcinoma]

One hundred and thirty-two patients with hepatocellular carcinoma in stages III and IV were studied. Seventy-six patients who underwent hepatectomy were divided into three groups: relative curative resection (RC: n = 30), relative noncurative resection (RNC: n = 30) and absolute noncurative resection (ANC: n = 16). Fifty-six patients were treated by non surgical procedures such as hepatic arterial infusion, transcatheter arterial embolization, ethanol injection and hyperthermia. The cumulative survival rate of hepatectomy patients was significantly better than that of non-surgically treated patients. The most significant prognostic factor was the presence of the portal venous invasion. In the patients without tumor thrombi or with tumor thrombi found microscopically, the cumulative survival rates of both RC and RNC were significantly better than those of ANC and non-surgically treated patients, but in the patients with tumor thrombi found grossly, there was no difference between hepatectomy patients and non-surgically treated patients. These results indicate that surgical treatment for advanced hepatocellular carcinoma improve the prognosis of the patients without tumor thrombi found grossly.
