The Comparison of Helical-IMRT, Direct-IMRT and 3D Radiotherapy Modalities in Breast Radiotherapy Planning

Öz:
OBJECTIVEThis study aims to compare dosimetric 3D-CRT, Tomo-helical IMRT and Direct IMRT methods inintact breast irradiation.METHODSRadiotherapy was planned with three different techniques simulated images of 30 breast cancer patientswith negative lymph nodes who underwent breast-conserving surgery.RESULTSThe maximum and minimum doses, homogeneity and conformity index and cold-zone volumes werefound to be different in all three techniques (p<0.001). The PTV boost maximum doses and homogeneityindex were found to be different (p<0.001). The maximum non-PTV dose (110% volume) and thehot zone volumes grasped by these doses, the V5 volume of the body and V5 volumes, outer of PTVwere found to be statistically significant for all three techniques (p<0.001). A statistically significant differencewas found between the three techniques concerning the ipsilateral lung V5 and V20 volumes,the contralateral lung V5 and V10 volumes and the counter breast maximum and mean doses (p<0.001).The mean and V10 volume of the heart was statistically significant (p<0.001), while the left breast irradiationand mean values were not statistically significant between the three techniques (p=0.529).However, there was a statistically significant difference in the V10 volume of the left breast irradiationbetween the three techniques (p=0.033).CONCLUSIONAccording to 3D-CRT, it is possible to achieve better dose distribution and dose homogeneity with Tomo-helical and direct IMRT. Low dose volumes are high with tomo-helical IMRT. Tomo-helical IMRTplanning provides better ipsilateral lung and heart doses but causes an increase in heart dose/contralateralbreast and for right breast irradiation causes an increase in heart dose.
