This is a study to evaluate the incidence of sampling bias during pathologic assessment of sentinel lymph nodes (SLN) when they are cut at a certain thickness (1 mm) and the tissue slices are completely analyzed by histopathology (at 200 µm sections). The sponsor and investigators would like to determine how often small cancer deposits are present in one slice but not the other. The data will provide an empirical estimate of the incidence of tissue sampling bias inherent in using different tissue sections for analysis. The data will also show how varying degrees of detail in evaluating the sentinel lymph nodes (SLN) with histopathology methods will impact the degree of agreement.

In this study, navigation of lymphatic passage after sentinel lymph node with indocyanine green was performed during axillary lymph node dissection in breast surgery . By comparing the con...
Sentinel lymph node biopsy（SLNB） is an established way of predicting axillary nodal metastasis in early breast cancer. We aim to determinethe，in a prospective randomized, controlled ...
The purpose of this study is to investigate the relevance of sentinel node in endometrial cancer. Sentinel node is thought to reflect the status of lymph node. Only 10 to 20% of women with...
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...
The standard treatment of localized breast cancers consists of surgical removal of the tumor at the breast or removal of the entire breast and lymph nodes (sentinel lymph node and / or axi...
Adequate lymph node evaluation is recommended for optimal staging in patients with malignant neoplasms including breast cancer. However, the role of negative lymph nodes (LNs) remains unclear in breas...
This study aims to explore the accuracy, specificity and laws of axillary lymph node metastasis predicted by sentinel lymph node biopsy (SLNB) by comparing axillary lymph node status via SLNB and axil...
The presence of lymph node metastases is one of the most important factors in breast cancer prognosis. The most common strategy to assess the regional lymph node status is the sentinel lymph node proc...
Sentinel-lymph-node (SLN) resection seems to minimize systematic axillary-lymph-node dissection (sALND) side effects in operated breast cancer patients. We explored whether SLN resection achieves simi...
Methylene blue dye is easy to obtain in developing countries and can be used in sentinel lymph node mapping for breast cancer. However, the accuracy of methylene blue alone for sentinel lymph node map...
First lymph node to receive drainage from the primary tumor. SENTINEL LYMPH NODE BIOPSY is performed to determine early METASTASIS status because cancer cells may appear first in the sentinel node.
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.
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.
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.
The historic designation for scrofula (TUBERCULOSIS, LYMPH NODE). The disease is so called from the belief that it could be healed by the touch of a king. This term is used only for historical articles using the name "king's evil", and is to be differentiated from scrofula as lymph node tuberculosis in modern clinical medicine. (From Webster, 3d ed)
