Radiotherapy was performed bilaterally by two opposing fields of 6 MeV photons by Linac D-2300 CD Varian (Palo Alto, CA, USA). The irradiation was administered after placement of a 0.5 cm thick bolus on each breast to limit drastically the “build-up” effect and then insert the skin into the clinical target volume (CTV). A total dose of 30 Gy on each breast was administered. Organ at risk’s dose was reduced to minimize to toxic effects (2.5 Gy to 20% of the right lung; 1.5 Gy to 20% of the left lung; and heart mean dose 1.018 Gy and maximum dose 11.731 Gy).
