Assessment of acute toxicities and early local recurrences in post mastectomy breast cancer patients by accelerated hypofractionated radiotherapy; a single arm clinical trial.

Purpose: Hypofractionated post mastectomy radiotherapy (PMRT) is commonly given using conventional radiotherapy technique. Volumetric modulated arc therapy (VMAT) and Intensity modulated radiation therapy (IMRT) are better sparing heart and lungs. This study was conducted to assess the toxicity profile and dosimetry outcomes of patients receiving PMRT using IMRT or VMAT.
