Brief summary
The purpose of this trial is to show adequate assay performance on clinical samples tested in real time at the clinical site.
Detailed description
This study will determine the sensitivity, specificity, negative predictive value, and positive predictive value of the GeneSearch™ BLN Assay in patient samples by comparing its performance to that of the current methods -- permanent section Hematoxylin and Eosin (H&E) staining with IHC. Additional marker testing using probes associated with nodal metastases may be used in the assay performance calculations. The observed performance measures will be compared to those obtained in the larger U.S. registration trial to show that there are no differences in the assay's performance.
Interventions
For in vitro diagnostic use only. The GeneSearch™ Breast Lymph Node (BLN) Assay is a qualitative, in vitro diagnostic test for the rapid detection of greater than 0.2 mm metastases in nodal tissue removed from sentinel lymph node biopsies of breast cancer patients. Results from the assay can be used to guide the intra-operative or post-operative decision to remove additional lymph nodes. Post-operative histological evaluation of permanent sections of the tissue specimen, in accordance with usual diagnostic practice and using the Veridex lymph node cutting scheme, is required.
