Coverage of Axillary Lymph Nodes with Tangential Breast Irradiation in Korea: A Multi-Institutional Comparison Study
Introduction. To evaluate the dose distribution and coverage of axilla using only tangential field for whole breast radiotherapy (RT) at three institutions in Korea. Methods. We used computed tomography (CT) images of nine consecutive 1-2 sentinel lymph node-positive patients who underwent breast conserving surgery and whole breast RT without axillary lymph node (ALN) dissection for clinical T1...
متن کاملStandardization of whole breast radiotherapy is required for safe omission of axillary lymph node dissection in breast cancer patients
Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...
متن کاملVirtual lymph node analysis to evaluate axillary lymph node coverage provided by tangential breast irradiation
PURPOSE To investigate the coverage of axillary lymph node with tangential breast irradiation fields by using virtual lymph node (LN) analysis. MATERIALS AND METHODS Forty-eight women who were treated with whole breast irradiation after breast-conserving surgery were analyzed. The axillary and breast volumes were delineated according to the Radiation Therapy Oncology Group (RTOG) contouring a...
متن کاملRelationship between Non-Technical Factors and Diagnostic Accuracy of Frozen Section in Axillary Lymph Nodes in Patients with Breast Cancer
Background and purpose: Regional lymph node involvement is one of the main prognostic factors for breast cancer. Intraoperative assessment of sentinel lymph node biopsy (SLNB) by frozen section (FS) allows necessary axillary lymph node dissection (ALND) at the same time. But, false negative results are the main problems of the FS. The aim of this study was to investigate the relationship betwee...
