In contrast, the polymorphism of the IL-1A (rs3783553) gene presented its Ins/Ins genotype as being associated with a higher risk of developing NSCLC (p = 0.033; OR = 2.002; 95% CI: 1.059–3.546), which was similar to the allele Ins. The gene discussed is IL1A; the disease is non-small cell lung carcinoma.
