Abstract

Abstract : Background: The incidence of hepatocellular carcinoma (HCC) is significantly higher in men than women. Nonetheless, the impact of sex disparities on HCC outcomes remains unclear. We aimed to compare the clinical manifestations and prognoses between male and female patients with HCC. Methods: This retrospective study enrolled 5337 consecutive patients (3976 men, 1361 women) who were diagnosed with HCC from 2007 to 2020. The prognostic factors were identified by the Cox proportional hazards model. Results: Male patients were younger upon HCC diagnosis (median age 64 vs 69 years; p < 0.001) with more favorable hepatic functional reserves (39.0% vs 35.1% albumin-bilirubin grade 1; p = 0.025) but had greater tumor burdens than the female patients. Furthermore, fewer male patients underwent curative therapies for HCC compared with the female patients (49.0% vs 57.0%; p < 0.001). After a median follow-up of 20.1 months (interquartile range, 5.8-47.3 months), 3133 patients died. The cumulative 5-year overall survival rates were 37.1% and 41.9% for male and female patients, respectively ( p < 0.001). From the multivariate analysis, male sex was not an independent factor predictive of poor overall survival in all patients and in the subgroup analysis stratified by treatment modalities. When stratified by age, the female sex was an independent factor associated with lower mortality in younger (≤50 years) patients but not in older patients with HCC. Conclusion: Sex was not an independent predictor of the outcome of patients with HCC, especially for those aged more than 50 years.
