Comparison of dosimetric radiotherapy of whole left- breast cancer using conventional tangential wedge-based techniques (CTT) and three intensity modulation techniques (IMRT)
Introduction: Whole breast radiotherapy after breast-conserving surgery decrease the risk of local recurrence. this study investigates the dosimetric aspects of intensity modulated radiotherapy (IMRT) compared to conventional tangential wedge-based beams techniques (CTT) of the whole breast in early stages breast cancer patients. Materials and Methods: Co...
متن کاملTangential beam IMRT versus tangential beam 3D-CRT of the chest wall in postmastectomy breast cancer patients: A dosimetric comparison
BACKGROUND This study evaluates the dose distribution of reversed planned tangential beam intensity modulated radiotherapy (IMRT) compared to standard wedged tangential beam three-dimensionally planned conformal radiotherapy (3D-CRT) of the chest wall in unselected postmastectomy breast cancer patients METHODS For 20 unselected subsequent postmastectomy breast cancer patients tangential beam ...
متن کاملComparison of forward intensity modulated radiation therapy and two field tangential wedged beam techniques in radiotherapy of breast cancer: dosimetric and radiobiologic study
Introduction: This study aims to compare the dose delivery parameters and radiobiologic model prediction of Tumor Control Probability (TCP) of the FIMRT technique compared with rectangular two tangential wedged fields (2FW) in the treatment of breast cancer. Furthermore, reduction of the heart and lung dose in the FIMRT was studied via dosimetric parameters and radiobiologic mo...
متن کاملDosimetric comparison of left-sided whole breast irradiation with 3D-CRT, IP-IMRT and hybrid IMRT.
The aim of this study was to compare the dosimetric characteristics of left-sided whole breast irradiation among 3-dimensional conformal radiotherapy (3D-CRT), 4-field inverse-planned intensity-modulated radiotherapy (IP-IMRT) and hybrid IMRT technique (combining 3D-CRT beams and IP-IMRT beams) with respect to target coverage and irradiation of organs at risk. The 3 different planning technique...
متن کاملLeft-Sided Whole Breast Irradiation with Hybrid-IMRT and Helical Tomotherapy Dosimetric Comparison
PURPOSE Limited-tomotherapy and hybrid-IMRT treatment techniques were compared for reductions in ipsilateral and contralateral lung, heart, and contralateral breast radiation doses. METHODS AND MATERIALS Thirty consecutively treated left-sided early-stage breast cancer patients were scheduled for lTomo and hIMRT. For the hIMRT plan conventional tangential-field and four-field IMRT plans were ...
