(A) Unadjusted overall survival of elderly patients with unresected stage I and II NSCLC according to whether they were treated with radiotherapy (RT). Overall survival was significantly better among patients treated with RT (P < 0.0001). (B) Unadjusted lung cancer-specific survival of elderly patients with unresected stage I and II NSCLC treated with and without RT. Patients treated with RT had significantly better lung cancer specific survival compared with those who were not treated (P < 0.0001).
