Eventual role of EGFR-tyrosine kinase inhibitors in early-stage non-small-cell lung cancer
Abstract
Nonadvanced non-small-cell lung cancer (NSCLC) has a poor long-term survival from surgery or definitive radiation that is minimally improved with induction/adjuvant conventional chemotherapy. EGFR-tyrosine kinase inhibitors (TKIs), which provide a significant benefit for molecularly selected EGFR-mutant patients with advanced NSCLC, have been infrequently explored in nonadvanced NSCLC to date. Current published studies reported no significant benefit from adding EGFR-TKI to the induction/adjuvant setting. However, many of them present eventual biases such as unpowered statistics, lack of molecular selection, recruitment of low-risk NSCLC, low sample size or unsuitable control arms. Results, strengths and deficiencies of completed and ongoing trials were fully discussed. Similarly, the selection of patients and control arms, the duration and risks of EGFR-TKI therapies in early-stage NSCLC, the evaluation of response and the diagnosis of EGFR status were considered and analyzed.
Keywords: EGFR-tyrosine kinase inhibitor; adjuvant treatment; early stage; induction treatment; locally advanced stage; non-small-cell lung cancer.
