Clinicopathologic Features and Long-Term Outcomes of Chinese Patients with Hepatocellular Carcinoma in Non-Cirrhotic Liver

Most hepatocellular carcinomas (HCC) are associated with cirrhosis. The clinicopathologic characteristics and outcomes of HCC present in non-cirrhotic livers are not well known in Chinese patients. This study was performed to explore the features of these patients and their outcomes after hepatectomy.96 patients with histologically confirmed HCC in non-cirrhotic liver who underwent partial hepatectomy between 1995 and 2001 in our cancer center were reviewed. A retrospective analysis of the clinicopathologic features was performed, and survival of patients was analyzed by the Kaplan-Meier method and Cox regression model.Operative mortality and morbidity were none and 8.3% (8/96), respectively. Postoperative overall survival (OS) rates at 1, 3, 5 and 10 years were 84.4, 62.5, 47.9 and 38.2%, respectively, with a median OS of 57 months. Disease-free survival (DFS) rates at 1, 3, and 5 years were 56.3, 39.6, and 33.3%, respectively, with a median DFS of 18 months. TNM stage was an independent prognostic factor for both OS and DFS of non-cirrhotic HCC. Operative blood loss was an independent prognostic factor for OS and DFS of patients who received curative resection.Curative partial hepatectomy was an effective and safe treatment for non-cirrhotic HCC. Aggressive local therapies were recommended for patients with intrahepatic recurrence.
