CXCR2 and endometrial cancer: Similarly, it was observed that the women who were GA heterozygous for the CXCR2 SNP had an approximately threefold higher risk of endometrial cancer (OR 3.03 95% CI 1.64–5.59 in the codominant model and OR 3.21 95% CI 1.79–5.73 in the overdominant model, p ≤ 0.001, see Table 4).
