Abstract: The purpose of this study was to evaluate
the dosimetrics value of the 
Tomo
Helical (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 (OARs),
sided lung and contralateral breast in TH plans. There was no difference
between the values of Conformity Index (CI) and Homogenity Index (HI) of both
plans (p>0.05). The values of Dmean, V5 and V20 of the sided lung in Tomo
Helical with block (HTb) were significantly lower than that Tomo Helical with
no block (TH) for all 17 patients (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 (p=0.004, p=0).
Both of HTb and TH plans produce acceptable target dose covarage in intact
breast Radio Therapy (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.
