Abstract

Background: Frozen section biopsy has been widely used for intraoperative diagnosis and evaluation of sentinel lymph nodes, so a decision can be made regarding whether to perform axillary clearance during primary surgery. This study aims to discuss the reliability of a simpler and faster method - touch imprint cytology - in the interpretation of metastasis from breast cancer. Methods: A retrospective review of 41 sentinel lymph node biopsies from patients with breast cancer were examined by intraoperative imprint cytology using rapid Diff-Quick staining. Paraffin-embedded permanent sections were examined using hematoxylin and eosin stained sections from the sentinel lymph nodes in collaboration with the employment of an anti-cytokeratin antibody. Results: Sixteen of all sentinel nodes harbored metastases in the paraffin sections, of which all 16 were identified by imprint cytology (sensitivity 93%). Conclusion: Touch imprint cytology is a fast and reliable alternative for intraoperative evaluation of sentinel lymph nodes in breast cancer patients.
