Background: Hepatocellular carcinoma (HCC) is an aggressive solid tumor. HCC occurred at younger and elder ages were considered driven by different oncogenic mechanisms, and they demonstrated distinct clinical courses. Methods: A total of 382 HCC patients treated by surgical resections was analyzed. Results: A univariate-multivariate analysis showed that viral etiology (chronic hepatitis B, C) and the UDP glucuronosyltransferase family 2 member B28 (UGT2B28) genomic variant rs2132039 were independently associated with the age at presentation of HCC (all adjusted P < 0.05). An extensive evaluations of clinicalpathological factors showed that the age (Odds ratio [OR], 1.016; 95% confidence interval [CI], 1.001-1.032; adjusted P = 0.037) and ascites (OR, 3.505; CI, 1.358-9.048; adjusted P = 0.010) were two independent factors associated with this genomic variant. The age was 54.1 ± 14.6 years for patients with the "TT" variant type, and 58.2 ± 13.7 years for those with the "Non-TT" variant type. The age disparity was most prominent in alcoholic patients (OR, 1.079; CI, 1.035-1.125; P < 0.001, age of "TT", 49.6 ± 12.2; age of "non-TT", 59.3 ± 10.7). This genomic variant was also associated with age of recurrence (P = 0.025), distant metastasis (P = 0.024) and HCC-related death (P = 0.008) in non-censored patients. Conclusions: An UGT2B28 genomic variant was indicative of the age of HCC presentation, recurrence, distant metastasis and death.
