BRCA1 and non-small cell lung carcinoma: The stepwise multivariate Cox analysis showed that BRCA1 rs1799966 (TC+CC vs. TT: HR = 0.617, 95% CI = 0.402−0.948, p = 0.028), radiation therapy (ever vs. never: HR = 0.611, 95% CI = 0.396−0.944, p = 0.027), and smoking (never vs. ever: HR = 0.574, 95% CI = 0.373−0.882, p = 0.011) independently predicted favorable survival of the advanced NSCLC patients.
