Impact of RASSF1A gene methylation on the metastatic axillary nodal status in breast cancer patients
Hypermethylation of CpG islands is a hallmark of cancer and occurs at an early stage in breast tumorigenesis. To gain insight into the epigenetic switches that may promote and/or contribute to the initial neoplastic events during breast carcinogenesis, the present study focused on the DNA methylation profile of invasive breast carcinoma. The aim of the study was to evaluate the prognostic signi...
BACKGROUND Tumour stage and the appropriate course of treatment in patients with breast cancer are primarily characterized by the state of metastasis in the axillary lymph nodes. In recent years, substantial research has focused on the prediction of lymph node status based on various pathological and molecular markers in order to obviate the necessity to carry out axillary dissection. In the pr...
The status of axillary lymph nodes is a key prognostic indicator in patients with breast cancer and helps guide patient management. Sentinel lymph node biopsy is increasingly being used as a less morbid alternative to axillary lymph node dissection. However, when sentinel lymph node biopsy is positive, axillary dissection is typically performed for complete staging and local control. Axillary u...
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 ...
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 ...
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...
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...
