Comparing Efficacy Between Anti-microtubule and Non-anti-microtubule as 3th Therapy After 2nd Line EGFR-TKI Therapy

This is an observational prospective study that investigates only daily practice. The prescription of anti-cancer medicine is separated from the decision to include the patient in this study. In addition, the assignment of the patient to a particular therapy or therapeutic strategy is not decided in advance by this study protocol, but falls within current practice.
