Objective: To examine the dosimetric effect of Breast Cancer (BC) patients Receiving Radiotherapy (RT) with Volumetric-Modulated Arc Therapy (VMAT). Methodology: This retrospective study enrolled 53 BC women, treated with VMAT between Oct 2013 and Nov 2018. The fractionation was within 40 Gray-50 Gray (Gy) in 15-25 fractions. Dosimetric parameters, Homogeneity Index (HI), Conformity Index (CI), Mean Heart Dose (MHD), and doses to the Ipsilateral Lung (IPL) and Mean Contralateral Breast (MCB) were analyzed. Results: Dosimetric results for 50 Gy/25 Fx showed, D98% (mean ± standard deviation) was 47.5± 0.8 Gy, PTV D2% was 53 ± 0.4 Gy, and D50% was 51 ± 0.3 Gy. The maximum point dose (Dmax), mean ± SD was 110 ± (1.4) and the minimum point dose (Dmin), was 72.. Read More»
