Overview
Brief Summary
The aim of this study is to investigate the efficacy and safety of intercalated combination of erlotinib and radiotherapy for patients with EGFR-mutant, unresectable, locally advanced NSCLC, and to explore a new treatment strategy for this subset. After Induction by erlotinib, local radiotherapy is intercalated, and followed by 24-week erlotinib maintenance.
Detailed Description
Chemoradiation therapy is the standard treatment for unresectable, locally advanced NSCLC, but its efficacy reaches a platform, and treatment-related life threatening toxicity limits its use. The EGFR tyrosine kinase inhibitors (TKIs) produce a dramatic response in patients carrying EGFR activating mutations in the metastatic setting. Multiple prospective trials show that EGFR-TKIs have a better tolerability when compared with chemotherapy.
