Hepatoblastoma (HB) is the most prevalent primary hepatic cancer in children aged 6 months to 3 years. LIN28A is recurrently mutated in various diseases, and critically involved in tumorigenesis. However, a limited number of studies have examined the involvement of LIN28A polymorphisms in HB risk. We used the TaqMan assay to genotype four LIN28A polymorphisms (rs3811464 G>A, rs3811463 T>C, rs34787247 G>A, and rs11247957 G>A) in 275 Chinese children with HB and 1018 cancer-free controls from five medical centers in China. Their association with HB risk was evaluated on the basis of odds ratio (OR) and corresponding 95% confidence interval (CI). Overall, no significant associations were found in single locus and combine analysis. Interestingly, in the stratified analysis, we found that subjects with 1-3 risk genotypes were more likely to develop HB in patients ≥17 months of age (adjusted OR=1.76, 95% CI=1.04-2.98, P=0.034). The rs3811464 GA/AA genotypes were associated with decrease HB risk in patients with clinical stage III+IV disease (adjusted OR=0.50, 95% CI=0.26-0.96, P=0.038). Our results suggest that the LIN28A polymorphisms have a weak association with HB susceptibility in the Chinese children. LIN28A rs3811464 G>A may decrease HB risk in stage III+IV patients which need further validations with larger samples and different ethnicities.
