Definitive Radiotherapy for Local Recurrence of NSCLC After Surgery
Programmed Cell Death 1 Receptor
To our knowledge, this is the largest reported series of LR-NSCLC treated with definitive RT. Survival appears comparable to or greater than that of primary NSCLC. Subsequent LRF is more common than distant failure. Established prognostic factors for primary NSCLC, such as chemotherapy and stage, were not clearly prognostic in this analysis. IMRT and higher RT doses were associated with improved survival, though IMRT patients were also treated more recently. These data support definitive-intent RT with optimal dose and technique in such patients.
