Impact of dose to lung outside the planning target volume on distant metastasis or progression after SBRT for early-stage non-small cell lung cancer.

ABSTRACT: Mean dose (EQD2) to 3-cm shell of lung surrounding the PTV was evaluated for association with distant metastasis and PFS after SBRT for stage I NSCLC. Dose was uniformly above previously determined threshold and metastasis was uncommon. An association between outcomes and mean EQD2 could not be confirmed or refuted.
