Does the Benefit of Sentinel Node Frozen Section Vary Between Patients With Invasive Duct, Invasive Lobular, and Favorable Histologic Subtypes of Breast Cancer?

Abstract

For patients with ID and IL cancers, the overall sensitivity of FS is >50%, but the yield of FS is <10% for individuals > or =60 years of age with T1a/b tumors. Intraoperative FS may not be worthwhile for this low-yield subset, especially for patients with invasive breast cancer of favorable type.
