Impact of thoracic radiation therapy after chemotherapy on survival in extensive‐stage small cell lung cancer: A propensity score‐matched analysis

Abstract

The role of thoracic radiation therapy (TRT) after chemotherapy (CHT) in extensive‐stage small cell lung cancer (ES‐SCLC) has not been well defined. We investigated whether intensity‐modulated radiotherapy (IMRT) improves outcomes in ES‐SCLC after CHT compared to CHT alone.
