IMPORTANCE Nodal ultrasonography with needle biopsy of abnormal lymph nodes helps to define the extent of breast cancer before neoadjuvant chemotherapy. A clip can be placed to designate lymph nodes with documented metastases. Targeted axillary dissection or selective removal of lymph nodes known to contain metastases (clip-containing nodes) as well as sentinel lymph nodes (SLNs) may provide mo...
The new staging technique of sentinel node biopsy facilitates the identification of pathological node negative patients in whom axillary dissection may be avoided; however, patients with a positive sentinel node biopsy would require a thorough examination of their nodal status. Axillary dissection provides good local control, accurate staging and prognostic information for decisions about adjuv...
Male breast cancer is a rare disease, often with a late presentation and poor prognosis. The mainstay of treatment is modified radical mastectomy, with axillary node dissection to assess stage, prognosis and the need for adjuvant treatment. When matched for age, tumour size, grade and axillary nodal status, the prognosis is similar for males and females. Concerted efforts must be made to educat...
Invasive breast cancer is the most common malignancy in women. Its most common site of metastasis is represented by the lymph nodes of axilla, and the sentinel lymph node (SLN) is the first station of nodal metastasis. Axillary SLN biopsy accurately predicts axillary lymph node status and has been accepted as standard of care for nodal staging in breast cancer. To date, the morphologic aspects ...
OBJECTIVE To compare the efficacy of axillary radiotherapy (ART) with that of completion axillary lymph node dissection (cALND) in clinically node-negative breast cancer patients with a positive sentinel lymph node. METHODS A literature search was performed in PubMed, EMBASE and Cochrane Library by using the search terms "breast cancer", "sentinel lymph node biopsy", "axillary radiotherapy" o...
Since the performance of surgical procedures of the axilla in the treatment of early breast cancer is decreasing, the role of axillary ultrasound (AUS) as staging procedere has newly to be addressed. The aim of this study was to determine which patient or histopathological characteristics are related to false-negative AUS. In a retrospective study design data of 470 women with primary breast ca...
High-dose chemotherapy (HDCT) is currently under evaluation for high-risk primary breast cancer (HRPBC), defined by extensive axillary nodal involvement or inflammatory breast carcinoma. Phase II studies of HDCT for HRPBC show that 30-40% of patients eventually relapse. We retrospectively reviewed 176 patients enrolled in clinical trials of HDCT for HRPBC at the University of Colorado and analy...
Regional complications after axillary lymphadenectomy are common and usually involve perioperative skin dehiscence, wound infection, and seroma formation and later arm lymphedema. Gentle handling of tissues during operation, and routine use of closed catheter suction drainage with direct external axillary compression with immobilization of the shoulder after nodal dissection are advocated to mi...
Introduction: Quality assurance is an essential aspect of cancer care. Assessment of surgical quality in breast cancer is still evolving. Variability in surgical care among surgeons has been well documented in literature and we sought to investigate such variation between two groups of surgeons referring patients to our oncology center. Methods: A prospective review of patient records of all br...
Apical dominance is one of the fundamental developmental phenomena in plant biology, which determines the overall architecture of aerial plant parts. Here we show apex decapitation activated competition for dominance in adjacent upper and lower axillary buds. A two-nodal-bud pea (Pisum sativum L.) was used as a model system to monitor and assess auxin flow, auxin transport channels, and dormanc...
