“…Several studies have revealed that breast movements can affect the dose distribution with dynamic IMRT. [1819] However, Furuya et al . [20] reported that the effects of dose distribution were relatively small when both the factors of respiratory motion and setup error were evaluated simultaneously.…”

Aim of this study was to compare the dosimetric aspects of whole breast radiotherapy (WBRT) between an irregular surface compensator (ISC) and a conventional tangential field technique using physical wedges. Treatment plans were produced for 20 patients. The Eclipse treatment planning system (Varian Medical Systems) was used for the dose calculation: For the physical wedge technique, the wedge angle was selected to provide the best dose homogeneity; for the ISC technique, the fluence editor application was used to extend the optimal fluence. These two treatment plans were compared in terms of doses in the planning target volume, the dose homogeneity index, the maximum dose, ipsilateral lung and heart doses for left breast irradiation, and the monitor unit counts required for treatment. Compared with the physical wedge technique, the ISC technique significantly reduced the dose homogeneity index, the maximum dose, the volumes received at 105% of the prescription dose, as well as reducing both the ipsilateral lung and heart doses (P < 0.01 for all comparisons). However, the monitor unit counts were not significantly different between the techniques (P > 0.05). Thus, the ISC technique for WBRT enables significantly better dose distribution in the planning target volume.

“…For conventional tangential field WBRT, breast motion did not significantly affect the dose distribution within the breast tissue during radiation [10]. However, Xing et al [40] reported that breast motion during radiation delivery affected the dose distribution for WBRT using dynamic IMRT (DyIMRT). In their study, dose inhomogeneity increased in the CTV, and its minimal dose was decreased by 6-9%.…”

“…As a countermeasure for breast motion, we took MV images for patient positioning before every fraction of the treatment and that was performed both anterior-posterior and lateral. Several studies have suggested that breast motions can affect the dose distribution with IMRT [ 19 , 20 ]. However, Furuya et al evaluated the dosimetric impact of respiratory motion and setup error on whole breast tangential irradiation [ 21 ].…”
