Stereotactic ablative radiotherapy (SABR) can be a curative option for non‐small cell lung cancer (NSCLC) and oligometastatic lung disease. Volumetric modulated arc therapy (VMAT) has offered further advancements in terms of radiation dose shaping without compromising treatment times however there is potential for greater low‐dose exposure to the lung. This study was to assess whether VMAT lung SABR would result in any increase to the dosimetry parameters compared with three‐dimensional conformal radiotherapy (3D‐CRT) that could confer increased risk of radiation pneumonitis.
