AIM: The present study aimed to assess the association between IGF2/H19 genetic variants and susceptibility to platinum-based chemotherapy in epithelial ovarian cancer (EOC). METHODS: A total of 43 platinum-resistant (PR) and 138 platinum-sensitive (PS) EOC patients were recruited in our study. 21 polymorphisms in IGF2/H19 locus were genotyped by Sequenom MassARRAY assay. RESULTS: The frequencies of GG genotype in both rs3842761(C/G) and rs4244809(A/G) were significantly lower in PR group compared with those in PS group (9.76 vs 23.36%, p = 0.049; 9.76 vs 26.09%, p = 0.045; respectively). Compared with the AA genotype, rs4244809 GG genotype was associated with significantly reduced risk of platinum resistance (adjusted OR: 0.30; 95% CI: 0.10-0.91; p = 0.033). Further stratified analyses revealed that the SNPs of rs3842761 and rs4244809 were greatly related to PR risk in FIGO stage III-IV (rs3842761GG/CC+CG: adjusted OR: 0.15; 95% CI: 0.02-1.21; rs4244809 GG/AA+AG: adjusted OR: 0.24; 95% CI: 0.07-0.84; respectively) and serous adenocarcinoma subgroups (rs3842761 GG/CC+CG: adjusted OR: 0.21; 95% CI: 0.05-0.94; rs4244809 GG/AA+AG: adjusted OR: 0.19; 95% CI: 0.04-0.5; respectively), while rs7924316 polymorphism was associated with reduced risk of PR in serous adenocarcinoma subgroup as analyzed by a recessive model (rs7924316 GG/TT+TG: adjusted OR: 0.22; 95% CI: 0.05-0.98). In addition, both TCT haplotypes of rs3741206/rs3842761/rs7924316 and TC haplotype of rs3741206/rs3842761 were associated with elevated risk of PR (for the TCT haplotype of rs3741206/rs3842761/rs7924316: p = 0.049; OR: 1.69; 95% CI: 1.00-2.87; for the TC haplotype of rs3741206/rs3842761: p = 0.044; OR: 1.71; 95% CI: 1.01-2.88). CONCLUSION: These results suggest that polymorphisms in IGF2/H19 gene locus are associated with PR risk in EOC.
