EGFR and neoplasm: Patients harbouring EGFR mutation-positive tumours had longer survival in both gefitinib and docetaxel groups (median survival 14.2 and 16.6 months, respectively) than in the overall population (7.6 and 8.0 months, respectively), and in the population with wild-type EGFR (6.4 and 6.0 months, respectively), indicating that EGFR mutations have a positive prognostic role.
