Low-Dose-Area-Constrained Helical TomoTherapy-Based Whole Breast Radiotherapy and Dosimetric Comparison with Tangential Field-in-Field IMRT
BACKGROUND AND PURPOSE To present a novel helical TomoTherapy-based method for whole breast radiotherapy that has better dosimetry and also has acceptable low-dose regions for lungs, heart, and contralateral breast compared with tangential field-in-field IMRT (FIF-IMRT). MATERIAL AND METHODS Ten patients with left-side breast cancer were planned with low-dose-area-constrained helical TomoTher...
متن کاملOptimization of tangential fields arrangement in the breast cancer 3D conformal radiation therapy
Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
متن کاملA comparison of contralateral breast dose due to breast cancer radiotherapy using two different treatment machines in a radiotherapy center
Background: The radiation dose received by contralateral breast (CLB) is one of the concerns of breast radiotherapy, because it may lead to the induction of secondary breast cancer. The aim of this study was to evaluate the CLB surface dose in the breast treatment in Yazd radiotherapy center. Materials and Methods: The surface dose of CLB was measured using TLD dosimetry in 50 cancer breast pat...
متن کاملCardiac dose from tangential breast cancer radiotherapy in the year 2006.
PURPOSE To quantify the radiation doses received by the heart and coronary arteries from contemporary tangential breast or chest wall radiotherapy. METHODS AND MATERIALS Fifty consecutive patients with left-sided breast cancer and 5 consecutive patients with right-sided breast cancer treated at a large United Kingdom radiotherapy center during the year 2006 were selected. All patients were ir...
متن کاملDosimetric comparison of whole breast radiotherapy using field in field and conformal radiotherapy techniques in early stage breast cancer
Background: We aimed to compare field-in-field technique (FIF) with conformal tangential field radiotherapy (CRT) in terms of dosimetric benefits for early stage breast cancer radiotherapy. Materials and Methods: Twenty consecutive left-side breast cancer patients who underwent breast-conserving surgery were included to the study. For each patient, two different treatment plans were cr...
