Hepatic resection is not enough for hepatocellular carcinoma. A follow-up study of 92 patients

Abstract

We followed up 92 patients who underwent curative hepatic resection for hepatocellular carcinoma between 1982 and 1991. The long-term survival rates for these 92 patients for 1, 3, and 5 years were 98.8, 81.6, and 57.3%, respectively. As of May 1991, the carcinoma had recurred in 52 patients (56.5%). Recurrent tumors usually occurred in the residual liver within 3 years after surgery but were not always located near the primary lesion. The biologic characteristics of the primary tumors, such as serum alpha-fetoprotein, tumor size, number of tumors, and portal involvement, were closely related to recurrence and long-term survival. However, the type of hepatectomy performed on the primary tumor had little influence on recurrence or long-term survival. We conclude that recurrence cannot be avoided by hepatic resection alone, much less with limited resection; postoperative positive adjuvant therapy is required to prevent recurrence for patients with satellite nodule and/or portal involvement.
