Prevalence of occult metastases in axillary sentinel lymph nodes of breast carcinoma.

Recently, sentinel lymph node biopsy (SLNB) has been accepted as a standard method of assessment of axillary lymph nodes in breast cancer patients with no clinical lymphadenopathy. There is no standard pathologic method to evaluate sentinel lymph nodes. The purpose of this study is to evaluate the frequency of occult lymph node metastasis in sentinel lymph nodes via serial sectioning and immunohistochemical study with cytokeratin and its relationship with other clinicopathologic factors.

The value of touch imprint cytology and frozen section for intra-operative evaluation of axillary sentinel lymph nodes.

Background: Sentinel lymph node (SLN) biopsy is a procedure of choice to determine the axillary involvement in breast cancer. The most important intraoperative evaluation methods are touch imprint cytology (TIC) and frozen section (FS). Each of these techniques has its own drawbacks and it is still unclear which is preferred.

The efficacy of Tc-99m sestamibi for sentinel node mapping in breast carcinomas: comparison with Tc-99m antimony sulphide colloid.

Background: To study the value of periareolar intra-dermal injection of Tc-99m sestamibi (MIBI) for sentinel node mapping in breast carcinoma.

Material And Methods: Fifty patients with early-stage breast cancer were included in our study. 17.
