Survival Outcomes With Thoracic Radiotherapy in Extensive-Stage Small-Cell Lung Cancer: A Propensity Score-Matched Analysis of the National Cancer Database

摘要

The role of consolidative thoracic radiotherapy is unclear in extensive-stage small-cell lung carcinoma, for which chemotherapy is standard. We aimed to evaluate its effect on survival using a large national database using propensity-matching methods. On the basis of a cohort of >14,000 patients, we found its use in addition to chemotherapy was associated with a significant improvement in survival.
