Impact of GBBS algorithm on post-mastectomy scar boost irradiation of breast using catheter flap

Post-mastectomy radiation therapy significantly reduces locoregional recurrence rates, which can be achieved with external beam radiotherapy delivered to chest wall, followed by scar irradiation either by electron or high-dose-rate (HDR) mould brachytherapy. The present study evaluates dosimetric advantage of Acuros® BV, a TG-186 MBDCA, over TG-43 formalism using 192Ir source for HDR brachytherapy in chest wall scar boost using catheter flap.A...
