Intensity modulated radiation therapy (IMRT) reduces the dose to the contralateral breast when compared to conventional tangential fields for primary breast irradiation

Abstract

Primary breast irradiation with tangential IMRT technique significantly reduces the dose to the contralateral breast compared to conventional tangential field techniques.

Effect of Breathing Motion in Radiotherapy of Breast Cancer

“…The segment-based techniques offered the possibility of patient-specific intensity modulation in craniocaudal direction improving dose homogeneity with reduced volumes of hot spots, which is in good agreement with previous studies [3,18,23]. The optimization of dose was performed with forward planned segments delivered in step-and-shoot technique [27,36].…”

The Effects of Nonmagnetic Bolus on Contralateral Breast Skin Dose during Tangential Breast Irradiation Therapy

“…The average breast dose was similar to the results reported by Jone et al [2] and other measurement points also showed similar results in line with the reported study. The dose near the treatment site was found to be higher than the data reported by Ajay et al [14]. However, this could be due to the possible measurement at the inner point of measurement.…”

Dosimetric evaluation of whole breast radiotherapy using field-in-field technique in early-stage breast cancer

“…To date, several investigations of the use of the FIF technique to improve dose distribution have been reported [20,[26][27][28][29][30][31][32][33]. FIF techniques are able to decrease the scattered doses to the contralateral breast and other parts of the body compared with conventional tangential field techniques [34,35], because of the use of MLCs instead of PWs. In our study, the FIF-RT technique for WBRT significantly reduced the volumes receiving doses over the prescription dose in irradiated volumes and improved the dose homogeneity of PTV eval compared with the TanPW-RT technique.…”
