This study aims to prospectively investigate the local regional control, overall survival, treatment related toxicities and quality of life (QOF) of elderly stage I NSCLC patients receiving stereotactic ablative radiotherapy (SABR) with a moderate fractionation of 72 Gy/6 Gy/12 F (BED10 = 115 Gy). Patients' general characteristics, treatment modality, dose-volume histogram (DVH) parameters, toxicity profiling, quality of life, pattern of failure as well as survival time will be prospective recorded for the analysis.
This study aims to prospectively investigate the efficacy, toxicity and quality of life (QOF) of stereotactic ablative radiotherapy (SABR) using a moderate fractionation of 72 Gy/6 Gy/12 F (BED10 = 115 Gy) in a single arm of elderly ( ≥ 70) patients with stage I (2009 UICC) non-small cell lung cancer (NSCLC).
