ABSTRACT
The expression of IL-2RA and IL-2RB was correlated with breast cancer (BC) progression. However, there is no literature investigating the association of IL-2RA and IL-2RB polymorphisms with BC predisposition among Chinese Han Women. Seven SNPs in IL-2RA and IL-2RB were genotyped by Agena MassARRAY platform among 553 BC patients and 550 healthy controls. Odds ratios (OR) and 95% confidence interval (CI) adjusted for age were calculated for the effect of IL-2RA and IL-2RB variants on BC susceptibility. IL-2RA rs12722498 was a protective factor for BC occurrence (OR = 0.70, p = 0.019), especially in subjects with age ≤ 52 years (OR = 0.55, p = 0.004). IL-2RA rs12569923 (OR = 9.07, p = 0.033), IL-2RB rs2281089 (OR = 0.67, p = 0.043) and rs9607418 (OR = 0.59, p = 0.012) were related to the incidence of estrogen receptor positive (ER +) BC. IL-2RB rs3218264 (OR = 1.38, p = 0.010) and rs9607418 (OR = 0.56, p = 0.009) were associated with the risk of developing progesterone receptor positive (PR +) BC. Rs2281089 (OR = 1.54, p = 0.012) and rs1573673 (OR = 0.72, p = 0.035) were correlated to Ki-67 level. Moreover, IL-2RB rs2281089 (OR = 0.72, p = 0.022) showed a reduced risk of BC metastasis, and IL-2RA rs12722498 (OR = 0.54, p = 0.030) had a lower frequency in BC patients with tumor size > 2 cm. Our study identified the potential effect of genetic variations in IL-2RA and IL-2RB on BC susceptibility and/or BC clinicopathologic indicators among Chinese Han Women.
