background: the purpose of this study was to evaluate nodal irradiation with conventional three-field's technique. materials and methods: fifty patients with breast cancer were enrolled in this study. computed tomography scans in the supine treatment position were imported into a treatment planning system. levels i-iii axillary and supraclavicular nodes were identified and their depths to ...

b a ckground: the management of internal mammary (im) nodes in breast cancer lacks a well-defined consensus. lymphoscintigraphy identifies up to one-third of breast cancer patients with extra-axillary drainage, which is mainly located in the im chain. our aim in this meta-analysis is to identify the lymphoscintigraphy technique variables that effect im node identification. m ethods: an internet...

background: axillary nodal spread is an established prognostic factor in breast cancer. axillary nodal dissection and subsequent pathological examination is considered the gold standard technique of assessing the axilla for metastatic disease. a minimum of ten level i axillary nodes are required to be examined before an axillary specimen can be reliably labeled as disease free. this recommendat...

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...

background: the axillary and supraclavicular nodal volume treatment results in improvement of local control and survival after breast conserving surgery (bcs) or modified radical mastectomy (mrm). studies on the depth of these nodes have questioned the consistent use of standard fields for all patients. this study was done to assess the dose delivery to these lymph nodes with conventional treat...

background: the impact of positive intramammary lymph node (im ln) on the prognosis of patients with breast cancer has been debated for years; likewise, the standard management of patients with positive im ln remains unclear, especially when it is identified by preoperative imaging or by sentinel lymph node biopsy. the present study aims at reviewing the level of concurrent involvement of im ln...

introduction: size of axillary lymph nodes can be a predictor for breast abnormalities. the agents in the antiperspirants such as aluminum were observed in the breast biopsy of individual with abnormalities and antiperspirants usage. in this study, the relation between using antiperspirants and the size of axillary lymph nodes were evaluated in iranian women. methods: in this study, 120 women w...

background: in an attempt to reduce the risk of developing lymphedema following breast cancer surgery, some researchers suggested that by identifying and preserving the lymphatic plexus which drains ipsilateral arm we can minimize the risk of lymphedema. the procedure is known as axillary reverse mapping (arm). in the current study, we investigated the oncological safety of this technique. meth...

As we know breast cancer is the second death reason in Iran. One step of treatment process is radiotherapy, which needs careful consideration of contouring and therapeutic techniques Lung, thyroid, spinal cord, trachea and humerus are sensitive organs in breast cancer radiation therapy.  The most clinical studies recommended two ways for delivering 95 percent of dose to supraclavicular and ...
