Introduction: This study aimed to evaluate the association of obesity and diabetes mellitus (DM) comorbidity with hepatocellular carcinoma (HCC) recurrence and survival. Methods: We investigated 1,644 patients who underwent hepatic resection for solitary HCC without vascular invasion using computed tomography. Patients were categorized into four groups according to the combination of obesity and DM comorbidities: OB (+) or (−) and DM (+) or (−). Postoperative cumulative recurrence rates within and beyond 2 years and beyond 5 years were assessed. Results: Multivariate Cox proportional hazard regression analysis revealed that the adjusted hazard ratios (HRs) of reduced recurrence-free survival was 1.10 (95% confidence interval [CI]: 0.91–1.33; p = 0.31), 0.94 (95% CI: 0.78–1.12; p = 0.48), and 1.24 (95% CI: 1.01–1.54; p = 0.045) in the OB(+)DM(−), OB(−)DM(+), and OB(+)DM(+) groups compared with the OB(−)DM(−) group, respectively. Additionally, the corresponding adjusted HRs of reduced overall survival were 0.93 (p = 0.57), 0.97 (p = 0.76), and 1.38 (p = 0.013) for OB(+)DM(−), OB(−)DM(+), and OB(+)DM(+) groups, respectively. No significant difference in the early recurrence rate was determined among the four groups. The OB(+)DM(+) group demonstrated an increased risk for late recurrence beyond 2 years and 5 years postoperatively compared with the OB(−)DM(−) group (HR: 1.51; p = 0.024 and HR: 2.53; p = 0.046, respectively). The OB(+)DM(−) and OB(−)DM(+) groups demonstrated an increased risk for late recurrence beyond 5 years postoperatively (HR: 3.83; p < 0.001 and HR: 1.95; p = 0.037, respectively). Conclusions: Obesity and DM coexistence increased late recurrence and worsened prognosis in patients with HCC undergoing hepatic resection. The results help surgeons develop possible different surveillance protocol and need to focus on diabetes/obesity control during life-long surveillance for patients with HCC.
