Stereotactic body radiation therapy in the treatment of multiple primary lung cancers

SBRT for patients with MPLC appears to be a safe and effective local treatment alternative to surgery, particularly for medically inoperable patients. Patients with metachronous MPLC have encouraging survival rates, and thus local therapy appears justified. However, patients with synchronous MPLC have poor OS and PFS despite having excellent local control, and thus the utility of local therapy in this population requires further study.
