Purpose: Our aim is to define the sonographic criteria for assessing involved axillary nodes and to evaluate the accuracy of axillary ultrasound in the staging workup of individuals with breast cancer. Materials and Methods: 35 patients with breast cancer were prospectively evaluated with preoperative ultrasonography (US) to determine the presence of axillary lymph node metastasis. We determine...
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...
Management of the axilla is controversial. There has never been a widely agreed means of balancing an understanding of nodal status as prognostic information, the need to prevent axillary recurrence and the wish to avoid treatment-related morbidity, particularly arm lymphoedema. Balancing these conflicting requirements is difficult, particularly as the results of previous trials of locoregional...
Background. Sentinel node biopsy (SNB) represents the standard of care in breast cancer axillary evaluation. Our study aims to characterize the patterns of malignant cell distribution within the sentinel nodes (SN). Methods. In a retrospective IRB-approved study, we examined the anatomic location of the nodal area with the highest radioactive signal or most intense blue staining (hot spot) and ...
In this study, we evaluated the accuracy of a neural network in predicting 5-, 10- and 15-year breast-cancer-specific survival. A series of 951 breast cancer patients was divided into a training set of 651 and a validation set of 300 patients. Eight variables were entered as input to the network: tumor size, axillary nodal status, histological type, mitotic count, nuclear pleomorphism, tubule f...
Objective(s): This study sought to determine the diagnostic yield of SPECT/CT in localizing axillary sentinel lymph nodes (SLNs) in early breast cancer patients where planar scintigraphy (PS) was equivocal or negative.Methods: Prospective analysis of early stage breast cancer patients with nonpalpable axillary nodes undergoing SLN localization prior to nodal sampling for axillary staging. PS fi...
BACKGROUND The effect of internal mammary and medial supraclavicular lymph-node irradiation (regional nodal irradiation) added to whole-breast or thoracic-wall irradiation after surgery on survival among women with early-stage breast cancer is unknown. METHODS We randomly assigned women who had a centrally or medially located primary tumor, irrespective of axillary involvement, or an external...
