Completed

• Conditions: Breast Neoplasms; Breast Diseases
• Interventions: Device: OSNA Breast Cancer System

• Registration Number: NCT01368744
• Lead Sponsor: Sysmex America, Inc.

Brief Summary

The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System by comparing its performance to an extensive intraoperative frozen section protocol for Sentinel Lymph Nodes removed during standard Sentinel Lymph Node biopsy procedures from breast cancer subjects.
