Evaluation of dosimetric variance in whole breast forward-planned intensity-modulated radiotherapy based on 4DCT and 3DCT
This study was performed to explore and compare the dosimetric variance caused by respiratory movement in the breast during forward-planned IMRT after breast-conserving surgery. A total of 17 enrolled patients underwent the 3DCT simulation scans followed by 4DCT simulation scans during free breathing. The treatment planning constructed using the 3DCT images was copied and applied to the end exp...
متن کاملForward planned intensity modulated radiotherapy (IMRT) for whole breast postoperative radiotherapy. Is it useful? When?
The purpose was to compare the dosimetric results observed in 201 breast cancer patients submitted to tangential forward intensity-modulated radiation therapy (IMRT) with those observed in 131 patients treated with a standard wedged 3D technique for postoperative treatment of whole breast, according to breast size and supraclavicular node irradiation. Following dosimetric parameters were used f...
متن کاملCorrelation between target motion and the dosimetric variance of breast and organ at risk during whole breast radiotherapy using 4DCT
PURPOSE The purpose of this study was to explore the correlation between the respiration-induced target motion and volume variation with the dosimetric variance on breast and organ at risk (OAR) during free breathing. METHODS AND MATERIALS After breast-conserving surgery, seventeen patients underwent respiration-synchronized 4DCT simulation scans during free breathing. Treatment planning was ...
متن کاملAnalysis of Predictive Factors for Lung Injury after Forward-Planned Intensity-Modulated Radiotherapy in Whole Breast Irradiation
PURPOSE This study was performed to assess frequency, timings of occurrence, and predictors of radiologic lung damage (RLD) after forward-planned intensity-modulated radiotherapy (FIMRT) for whole breast irradiation. METHODS We retrospectively reviewed medical records of 157 breast cancer patients and each of their serial chest computed tomography (CT) taken 4, 10, 16, and 22 months after com...
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...
