Dosimetric comparison of single-arc/partial-arc volumetric modulated arc therapy and intensity-modulated radiotherapy for peripheral and central lung cancer.

Aim: The aim of this study is to compare the differences between intensity-modulated radiotherapy (IMRT) and single-arc/partial-arc volumetric modulated arc therapy (SA/PA-VMAT) techniques in locally advanced-stage non-small cell lung cancer (NSCLC).

Materials And Methods: Locally advanced 22 patients with NSCLC were evaluated retrospectively. Each patient underwent radiation therapy with either IMRT or SA-VMAT or 2PA-VMAT technique.
