Pooled analysis failed to provide statistical evidence for a significant association of ERCC1 rs3212961 polymorphism with overall lung cancer risk (homozygous: CC versus AA, OR = 0.87, 95% CIs: 0.71–1.07; heterozygous: CA versus AA, OR = 0.92, 95% CIs:0.77–1.11, dominant, CA/CC versus AA, OR = 0.90, 95% CIs: 0.76–1.07, and recessive model, CC versus AA/CA 0.91 95% CIs: 0.79–1.06) without substantial between-study heterogeneity(Table 2). Here, ERCC1 is linked to lung carcinoma.
