To elucidate the determinants of survival and the clinicopathologic features of long‐term survivors of resections for HCC, we reviewed 539 patients who had had hepatectomy alone or hepatectomy together with hepatic arterial ligation or ethanol injection for the treatment of hepatocellular carcinoma (HCC) at our department between 1973 and December 1992. Of these patients, 30% (79/264) survived for more than 5 years and 11% (10/87) for more than 10 years. All the long‐term survivors had received curative resections. The 5‐ and 10‐year survivors accounted for 58% (79/136) and 29% (10/35) of those with curative resections, respectively. Crucial determinants for long‐term survival were the absence of portal invasion and satellite nodules, a diploid pattern of DNA content, and a curative resection. A curative resection for diploid HCCs led to much better survival rates (73%) at 5 years than such a resection for aneuploid HCCs (35%), and than for non‐curative resections for aneuploid HCCs (0%). The history and tumor background of the ten patients who survived for more than 10 years were characterized by good reserve liver function, warranting a wider resection, predominance of female sex, single nodular growth, and the absence of poorly differentiated cells, in addition to the favorable conditions described above. Three of the ten patients developed a new lesion; these were successfully treated by re‐resection or repeated arterial embolization, since they were confined to the remnant liver and showed single nodular growth without extranodular spread. This analysis indicates that hepatectomy is the option of first choice for HCC patients with the potential for cure and good reserve liver function.
