Background: Hepatocellular carcinoma (HCC) is a common disease in Taiwan. A high incidence of recurrence after hepatectomy is the most important cause of unsatisfactory results after resection of HCC. This study aimed to determine the clinicopathologic factors for predicting survival >5 years without recurrence in HCC patients treated with hepatectomy.
Methods: The clinical features of 46 patients with surgically resected HCC who survived >5 years without recurrence (group A) were reviewed. Also, comparison was made with the clinical features and factors influencing the outcome of 1046 cases of resected HCC who survived <5 years both with and without recurrence and for >5 years with recurrence (group B).
Results: Of 1092 cases of surgically resected HCC, 46 (4.5%) survived >5 years without recurrence. Univariate analysis revealed that absence of vascular invasion, satellite lesions, low histological grading of HCC, a lower rate of underlying liver cirrhosis, wider resection margins, and an uneventful postoperative course were frequent in group A patients compared with group B patients. Moreover, multivariate stepwise logistic regression analysis identified an absence of satellite lesions and an uneventful postoperative course as the two main independently significant predictors of HCC patients undergoing hepatectomy with long-term disease-free survival. The 1-, 3-, 5-, and 10-year survival rates of group A patients were 100%, 100%, 100%, and 84.1%, whereas those of group B patients were 73.5%, 47.9%, 29.0%, and 21.2%, respectively.
Conclusions: An absence of satellite lesions and an uneventful postoperative course are the two main independent predictors for long-term disease-free survival in HCC patients undergoing hepatic resection.
