Real-World Outcomes of Resected EGFR-Mutated NSCLC patients treated with Adjuvant EGFR-TKI in China - ECHO

This is a multi-centre, observational study, with retrospective data collection and prospective active follow-up. The aim is to measure the treatment pattern and real-world outcomes of EGFR-TKI as an adjuvant therapy in patients with early-stage EGFR-mutated NSCLC. The study period ranges from July 1st, 2022 to June 30th, 2031. Approximately 2,000 patients will be enrolled from 15 sites in China.

This is a multi-centre, observational study, with retrospective data collection and prospective active follow-up. The study will enroll adult patients from China with resected, stage IB to III NSCLC who have received adjuvant EGFR-TKI therapy. Approximately 2,000 patients will be enrolled from 15 sites in China. Patients will be followed up from the index date to the earliest of death, loss to follow-up, or the end of study. Data accumulated before informed consent will be collected retrospectively. For prospective data collection, every 12-week data collection frequency will be performed for the first 1-year from index date; and every 24-week data collection frequency will be performed afterward until the end of follow-up. All study-relevant data occurring during the follow-up period will be captured irrespective of planned follow-up frequency, with collection conducted via medical record abstraction and/or telephone interviews.
