Description
The disease control rate of patients with GNAS1 T393C CC genotype was lower than that of patients with variant genotype (TT or CT) (46.2% vs 73.8%, P=0.039). Univariate analysis identified gender, smoking history, histology and GNAS1 T393C polymorphism as predictive marker of PFS (P=0.04, P<0.001, P<0.001 and P=0.005). Multivariate analysis of factors, including smoking history, performance status score, histology, GNAS1 T393C polymorphism demonstrated that GNAS1 T393C polymorphism was correlated independently with PFS (P=0.007). The data suggests the role of GNAS1 T393C CC genotype as a poor predictive marker both of DCR and PFS in advanced NSCLC patients treated with tyrosine kinase inhibitor.
