Importance: Evidence is lacking from randomized clinical trials to guide the optimal approach for stereotactic ablative body radiotherapy (SABR) in patients with pulmonary oligometastases. Objective: To assess whether single-fraction or multifraction SABR is more effective for the treatment of patients with pulmonary oligometastases. Design, Setting, and Participants: This multicenter, unblinded, phase 2 randomized clinical trial of 90 patients across 13 centers in Australia and New Zealand enrolled patients with 1 to 3 lung oligometastases less than or equal to 5 cm from any nonhematologic malignant tumors located away from the central airways, Eastern Cooperative Oncology Group performance..
