Clinical Outcomes and Safety Profile in the Treatment of Synchronous Nonmetastatic Lung Tumors With Stereotactic Body Radiation Therapy.

Purpose: Stereotactic body radiation therapy (SBRT) has increasingly been used to treat early-stage primary lung cancers, but its effectiveness and safety in patients with multiple synchronous primary lung tumors is not as well established. Our aim was to evaluate clinical outcomes, patterns of recurrence, and toxicities for these patients.

Methods And Materials: We queried an institutional database of patients treated with SBRT for primary lung tumors from 2007 to 2019.
