  Abstract Aim: To dosimetrically compare and evaluate Intensity Modulated Radiation Therapy (IMRT) versus conventional five field radiotherapy (5FCRT) in postmastectomy radiotherapy (PMRT). Material and Methods: This study included 25 consecutive patients for PMRT. Target volumes (chest wall, axilla, supraclavicular regions [SCF]) and normal structures (lungs, heart, spinal cord, opposite breast) were delineated on the planning CT scans. For each patient, one IMRT and one 5FCRT plan were generated for 50 Gy and corresponding dose volume histograms were compared. Differences in means of each set of variables were tested for significance.   Results: CTV and PTV of chest wall, IMC, axilla level l, ll, lll and SCF were evaluated by variables D98%,D2%, D50% V<95, V>105, V>107, homogeneity index (HI). Coverage of the PTV given chest wall was signi.. Read More»
