Based on this study and our study on endometrial cancer [8], we recommend follow-up of interactions between acrylamide intake and SNPs for ovarian and endometrial cancer risk, particularly SNPs in CYP2E1, GSTs, the HSD3B1/B2 gene cluster, AKR1C1, NQO1, GPX1 and MGC12965. Here, AKR1C1 is linked to endometrial cancer.
