Data Base Query 2004-2012 for Stage I-IV NSCLC with Thoracic RT
243,822 patients analyzed:
243,474 photons
348 patient treated with protons
Non-proton therapy was associated with significantly worse survival compared with
proton therapy (hazard ratio 1.21 [95% CI 1.06-1.39]; P<.01).
On propensity matched analysis, proton radiation therapy (nZ309) was associated with
better 5-year overall survival 22% versus 16% .
For stage II and III patients, non-proton radiation therapy was associated with worse
survival
compared with proton radiation therapy (hazard ratio 1.35 [95% CI 1.10-1.64], P<.01).
