ABSTRACT
Stereotactic ablative body radiation therapy (SABR) is a well-established alternative to surgery for early stage non-small-cell lung cancer (NSCLC). While SABR is typically delivered in 3 to 5 fractions, randomized trials have shown single-fraction SABR to be a reasonable alternative. We present the case of a 66-year-old male with history of cholangiocarcinoma who was subsequently diagnosed with peripheral early stage NSCLC and treated in mid-inspiration breath hold (BH) to 34 Gy in 1 fraction on a magnetic resonance (MR)-guided linear accelerator, with treatment delivery completed in 17 minutes. Visual biofeedback was utilized to maximize patient compliance with appropriate depth of inspiration BH and improve overall treatment delivery time efficiency. The benefits of single- vs multifraction SABR and unique advantages of MR guidance that are particularly well-suited for single-fraction SABR are reviewed.
