Interleukin-32 (IL-32) as a pro-inflammatory cytokine participates in the progression of inflammation and cancer. Ovarian cancer (OC) accounts for a considerable mortality rate, but research on IL-32 and OC is almost nil. Our study aims to explore the association between IL-32 and the progression as well as prognosis of OC initially. This hospital-based case-control study enrolled 147 OC patients and 337 healthy controls, and we used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to distribute the genotypes. The results showed that the homozygous genotype (TT) of rs28372698 SNP was significantly higher in patients compared to controls (12.9% vs. 6.2%, P = 0.018, OR (95% CI) = 2.23 (1.16-4.29)). This revealed that TT genotype might be a risk factor in OC progression. This present study indicates that IL-32 gene polymorphism relates to an increased OC susceptibility, and IL-32 may be a marker for OC progression.
