...the updated analysis of CTONG1103 indicated that erlotinib continued to improve PFS and OS numerically compared with platinum-based chemotherapy. Moreover, there was no evidence of cumulative toxicity in erlotinib during the long-term follow-up. The present results support the use of erlotinib in both the neoadjuvant and adjuvant settings for resectable stage IIIA-N2 EGFR-mutant NSCLC.
