ERCC2 and neoplasm: Stratified analysis by tumor size feature demonstrated that ERCC2-rs13181 CA genotype carriers displayed an elevated risk of BC with large tumor size (T3-T4) in heterozygote model (OR: 4.09, 95% CI: 1.14–14.7, p = 0.03) and overdominant model (OR: 4.38, 95% CI: 1.28–15.1, p = 0.014).
