title: Efficacy of hepatic resection for huge (≥ 10 cm) hepatocellular carcinoma: good prognosis associated with the uninodular subtype.
abstract: BACKGROUND
  The value of hepatic resection (HR) for huge hepatocellular carcinomas (HCC) (≥ 10 cm in diameter) remains controversial. The aim of this study is to evaluate the efficacy of hepatic resection (HR) for patients with huge HCC.
  
  
  METHODS
  A total of 739 patients with huge HCC (≥ 10 cm in diameter) (huge HCC group, n = 244) or small HCC (< 10 cm in diameter) (small HCC group, n = 495) who received initial HR were retrospectively analyzed. Overall survival (OS) and disease-free survival (DFS) were obtained using the Kaplan-Meier method and compared by Log-Rank test. Prognostic factors of huge HCC were identified based on Cox regression analyses.
  
  
  RESULTS
  The hospital mortality of these two groups were similar (P = 0.252). The 5-year OS of huge HCC group and small HCC group were 30.3% and 51.9%, respectively (P < 0.001). Uninodular huge HCC had a significant higher 5-year OS (50.6%) than mutinodular huge HCC (26.9%) (P = 0.016). Multivariate analysis revealed that uninodular huge HCC and absence of PVTT independently predicted better OS for huge HCC patients.
  
  
  CONCLUSIONS
  HR is a safe and effective approach for the treatment of huge HCC, especially for the uninodular subtype.
