Impact of tumor size and location on lung dose difference between stereotactic body radiation therapy techniques for non ‐small cell lung cancer

ConclusionsLung dose differences between the 3D-CRT and IMRT techniques for lung SBRT were mainly correlated with the PTV rather than location-related parameters. Together with the dosimetric benefit in high-dose lung regions of IMRT for larger tumors, the relative increases in the MLD and V20 for small-sized tumors could be reduced by applying a more rapid dose fall-off outside the PTV.
