title: Diabetes mellitus worsens the recurrence rate after potentially curative therapy in patients with hepatocellular carcinoma associated with nonviral hepatitis.
abstract: OBJECTIVE
  The aim of this retrospective study was to examine the relationship between diabetes mellitus and recurrence of hepatocellular carcinoma after potentially curative therapy for hepatocellular carcinoma with nonviral hepatitis.
  
  
  METHODS
  We studied 40 consecutive hepatocellular carcinoma patients who were diagnosed between 1980 and 2006 with hepatocellular carcinoma associated with non-B, non-C hepatitis, and later underwent surgical resection or radiofrequency ablation.
  
  
  RESULTS
  Twenty-two out of the 40 patients developed hepatocellular carcinoma recurrence within a median of 3.7 years. In the 18 patients with diabetes mellitus, the cumulative rates of hepatocellular carcinoma recurrence were 22.2% at the first year, 55.6% at the second year, 61.1% at the third year, 61.1% at the fourth year, and 80.6% at the fifth year. The cumulative rates of hepatocellular carcinoma recurrence in 22 nondiabetic patients were 24.6% at the first year, 24.6% at the second year, 31.5% at the third year, 31.5% at the fourth year, and 31.5% at the fifth year. The hepatocellular carcinoma recurrence rate was significantly higher in diabetic patients than in nondiabetics (P = 0.026). The multivariate Cox proportional model identified old age and diabetes as the only significant predictors for recurrence. The hazard ratio of hepatocellular carcinoma recurrence in diabetic patients was 4.61 (P = 0.007). There was no significant difference in overall survival rate between diabetic and nondiabetic patients (P = 0.392).
  
  
  CONCLUSIONS
  Diabetes is a significant predictor of tumor recurrence after potentially curative therapy for hepatocellular carcinoma in patients with nonviral hepatitis.
