Stereotactic body radiation therapy in the management of lung neoplasms: is it ready for prime time?

Purpose of review Advances in radiation delivery have expanded the scope of stereotactic body radiation therapy (SBRT) in lung cancer treatment, as it offers better local control, shorter treatments, and enhanced immunostimulation. This review summarizes recent literature regarding SBRT's role in nonoperable and operable early-stage, locally advanced, central, and oligometastatic nonsmall cell lung cancer (NSCLC), and its mixed results with immunotherapy. Recent findings Recent studies demonstrate SBRT achieves excellent local control in inoperable early-stage NSCLC and is being explored as an alternative to surgery for operable cases. Additionally, SBRT can be done safely in central tumors if strict dose limits to normal structures are observed. SBRT shows promise in locally advanced disease, as consolidative local therapy for oligoprogressive and oligometastatic disease and in combination with immune checkpoint inhibitors. Advances in adaptive radiation therapy and novel fractionation schedules, including ultra-hypofractionation and personalized approaches, further refine SBRT's role in lung cancer management, with more practice changing clinical trials on the horizon. Summary SBRT provides durable and well tolerated treatment for patients with localized and metastatic lung cancer. With ongoing trials exploring its synergy with immunotherapy and its applicability in operable patients and large tumors, SBRT is poised to play an even greater role in personalized lung cancer treatment.
