In the Original Investigation titled “Proton Beam Radiotherapy and Concurrent Chemotherapy for Unresectable Stage III Non–Small Cell Lung Cancer: Final Results of a Phase 2 Study,”1 published online July 20, 2017, there were errors in Figure 2a in the numbers at risk at 24, 48, 72, and 96 months. The correct numbers at risk are as follows: for overall survival, 36, 17, 11, and 2, and for progression-free survival, 21, 13, 8, and 1, respectively. This article was corrected online.
