A Phase II Trial of Individualized Stereotactic Ablative Radiotherapy for Lung Tumors (iSABR)

Stereotactic ablative radiotherapy (SABR) is an effective treatment for lung tumors, but can result in toxicity such as chest wall pain and life-threatening damage to central lung structures. We hypothesized that while larger tumors require higher dose, small tumors up to 10cc in volume can be controlled with biologically effective dose < 100Gy. In this phase II single-arm trial, we tested the hypothesis that individualizing lung SABR dose and...
