Abstract :Abstract: The purpose of this study was to evaluate the dosimetrics value of the Tomo Helical insert ignore into journalissuearticles values(TH); plans with complete block where located posterior of the sided lung compared to TH plans with no block in patients with intact breast cancer. TH plans with intact breast cancer were retrospectively created for 17 patients with blocked or no TH techniques in our clinic. The beam angles were arranged to cover PTV intact breast and to minimize doses to Organ at Risks insert ignore into journalissuearticles values(OARs);, sided lung and contralateral breast in TH plans. There was no difference between the values of Conformity Index insert ignore into journalissuearticles values(CI); and Homogenity Index insert ignore into journalissuearticles values(HI); of both plans insert ignore into journalissuearticles values(p>0.05);. The values of Dmean, V5 and V20 of the sided lung in Tomo Helical with block insert ignore into journalissuearticles values(HTb); were significantly lower than that Tomo Helical with no block insert ignore into journalissuearticles values(TH); for all 17 patients insert ignore into journalissuearticles values(p=0.01, p=0, p=0.002);. The values of Dmean and V5 of heart in HTb were significantly lower than that in TH insert ignore into journalissuearticles values(p=0.004, p=0);. Both of HTb and TH plans produce acceptable target dose covarage in intact breast Radio Therapy insert ignore into journalissuearticles values(RT);. Especially we produce lower dose V5 values in sided lung volume when, using complete block posteriorly. Aimed to decrease scattering low dose regions in irradiated volume and around the breast, so we may prevent probability of secondary malignancy in breast region.
