Sentinel lymph node biopsy in breast cancer.
Summary of "Sentinel lymph node biopsy in breast cancer."
Complete axillary lymph node dissection has been the traditional operation to determine whether cancer has spread beyond the breast. In the large majority of patients with breast cancer, lymphatic mapping and γ-probe-guided and/or blue dye sentinel node biopsy can be used to locate the first node in the axilla, and thereby provide important information about the status of axillary nodes. Patients without clinical involvement of the axilla should undergo sentinel node biopsy routinely. Thus, they may be spared complete axillary dissection if the sentinel node is negative. Decreased arm swelling and pain are associated with sentinel lymph node biopsy compared with axillary lymph node dissection.

Medical and Biotech [MESH] Definitions
Sentinel Lymph Node Biopsy
A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
Lymph Node Excision
Surgical excision of one or more lymph nodes. Its most common use is in cancer surgery. (From Dorland, 28th ed, p966)
Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
Inflammatory Breast Neoplasms
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
Local Lymph Node Assay
The local lymph node assay (LLNA) is an alternative method for the identification of chemicals that have the ability to cause skin sensitization and allergic contact dermatitis. Endpoints have been established so fewer animals are required and less painful procedures are used.
Sentinel lymph node biopsy has become a standard component of the evaluation of early-stage breast cancer, with a gradually increasing number of indications in this patient population. This report pre...
PURPOSE: The objective of this review is to summarize the evidence demonstrating that the sentinel lymph node (SLN) procedure is not only associated with significantly less morbidity compared to the a...
INTRODUCTION: We evaluated the incidence of micrometastasis and nonsentinel lymph node metastasis as well as local and axillary recurrence rates after level I-II axillary lymph node dissection. MATERI...
INTRODUCTION: Lymphoscintigraphy and sentinel node mapping is established in breast cancer and melanoma but not in esophageal cancer, even though many centers have shown that occult tumor deposits in...
We herein report a case of second sentinel lymph node biopsy (SLNB). A 57-year-old woman underwent breast-conserving surgery including axillary clearance at Aichi Cancer Center on October 20, 2003. Re...
RATIONALE: Diagnostic procedures, such as thoracoscopic sentinel lymph node biopsy, may help find breast cancer that has spread to lymph nodes between the breasts. It may also help doctors...
RATIONALE: Diagnostic procedures such as sentinel lymph node biopsy may improve the ability to detect breast cancer and determine the extent of disease. PURPOSE: Phase II trial to study t...
We continue to collect information in support of the hypothesis that the histology of the first draining lymph node (sentinel node) accurately predicts the histology of the rest of the axi...
Sentinel Lymph Node Biopsy and Primary Tumor Gene Expression Profiling in Finding Axillary Lymph Node Metastases in Women Who Have Received Neoadjuvant Therapy for Stage II, Stage III, or Stage IV Breast Cancer
RATIONALE: Sentinel lymph node biopsy and gene expression profiling of the primary breast tumor may help determine if tumor cells have spread to the axillary lymph nodes and help doctors p...
RATIONALE: Diagnostic procedures, such as lymph node mapping and biopsy, may improve the ability to detect the extent of colorectal cancer. PURPOSE: Diagnostic trial to study the feasibil...
