OBJECTIVE: The aim of this study was to evaluate the effects of surgical treatments for patients with stage IV-A hepatocellular carcinoma (HCC) without lymph node metastasis. SUMMARY BACKGROUND DATA: Nonsurgical therapy for highly advanced HCC patients has yielded poor long-term survival. Surgical intervention has been initiated in an effort to improve survival. METHODS: The outcome of 150 patients who underwent hepatic resection was studied. Survival analysis was made by stratifying stage IV-A HCC patients into two groups-those with and those without involvement of a major branch of the portal or hepatic veins. Those with involvement were further divided into subgroups according to major vascular invasions. RESULTS: Patients who had multiple tumors in more than one lobe without vascular invasion had a significantly better 5-year survival rate (20%) than those with vascular invasion (8%) (p < 0.01). The survival rate of patients with hepatic vein tumor thrombi (10%) was better than the rate for those with tumor thrombi in the inferior vena cava (0%), in whom no patients survived more than 2 years, although the survival rate for those with portal vein tumor thrombi in the first branch (11%) was no different from the rate for that in the portal trunk (4%). The operative mortality decreased from 14.3% in the first 6 years to 1.4% in the following 5 years. CONCLUSIONS: Surgical intervention for stage IV-A HCC patients brought longer survival rates for some patients. We recommend surgical intervention as an effective therapeutic modality for patients with advanced HCC.
