ABSTRACT
Indications for sentinel lymph node mapping (SLNM) for patients with ductal carcinoma in situ (DCIS) of the breast are controversial. We reviewed our institutional experience with SLNM for DCIS to determine the node positive rate and clarify indications for nodal staging in patients with DCIS. Since 1998 we have used SLNM to stage breast cancer patients using both blue dye and radiocolloid. In DCIS patients, SLNM has been reserved for patients considered at high risk for harboring coexistent invasive carcinoma or treated by mastectomy. All sentinel nodes were evaluated with serial sectioning, hematoxylin and eosin staining, and immunohistochemical evaluation for cytokeratins. We identified 44 patients with 46 cases of DCIS (two patients with bilateral disease). SLNM identified at least one sentinel node in all cases. In all cases, the sentinel node(s) were negative for axillary metastasis. We calculated the binomial probability of observing 0 of 46 cases as negative when the expected incidence according to published reports in the surgical literature was 13 per cent and found a P value of <0.01. Based on this case-series observation, we conclude SLNM should not be routinely performed for patients with DCIS. We now use SLNM only for DCIS patients treated by mastectomy.

    The detection of occult metastatic breast cancer cells by RT-PCR is limited by the poor specificity of most tumour mRNA markers. MAGE-A3 is a highly specific tumour mRNA marker that is not expressed in non-cancer cells. This study assesses MAGE-A3 mRNA as a molecular marker for the detection of...

    This article discusses the importance of staging of breast cancer and role of contrast ultrasound. High-resolution ultrasound (US) can be used to evaluate most of the parameters required for breast cancer staging. However, there are major problems in the accurate definition of tumor vascularity...

    Sentinel lymph node biopsy has stimulated interest in identification of micrometastatic disease in lymph nodes, but identifying small clusters of tumor cells or single tumor cells in lymph nodes can be tedious and inaccurate. The optimal method of detecting micrometastases in sentinel nodes has...

    After a positive sentinel lymph node (SLN) biopsy, some patients may be considered to have a very low risk of non-SLN involvement and could be candidates for axillary sparing. The aim of this study was to validate the nomogram created at the Memorial Sloan-Kettering Cancer Center (MSKCC) for the...

    Although several methods have been devised to examine sentinel lymph node (SLN) specimens in breast cancer, the extent of examination and whether it should routinely include multilevel sectioning to detect micrometastases (MM) (<2.0 mm) is still debated. In this study all "positive" SLN biopsies...
