Estimation by the Cox proportional hazards model showed that IGF-1R+1013(G/A) polymorphism is an independent prognostic factor (P=0.020), and IGF-1R+1013(G/A) polymorphism in combination with IGF-2R +1619(G/A) polymorphism is an independent prognostic factor in advanced NSCLC (P=0.025). Here, IGF2R is linked to non-small cell lung carcinoma.
