Summary
Intraoperative cytology accurately diagnosed most thoracic and breast lesions, guiding surgical extent. Histology confirmed complex cases, improving diagnostic reliability for various tumors.
Area of Science:
- Surgical Pathology
- Cytopathology
- Oncology
Context:
- Intraoperative cytology is crucial for rapid tissue diagnosis during surgery.
- Evaluating pneumomediastinal, mammary, and other focal lesions requires precise diagnostic methods.
- Hematoxylin-eosin staining and cytokeratin expression are key cytological techniques.
Purpose:
- To assess the reliability and utility of intraoperative cytology in diagnosing various pathological processes.
- To determine the effectiveness of fine-needle aspiration and scraping techniques in cytological analysis.
- To evaluate the role of cytokeratin expression in refining diagnoses, particularly for thymomas and epithelial hyperplasias.
Summary:
- Intraoperative cytology was performed on 236 pneumomediastinal, 251 mammary, and 45 other focal lesions.
- Diagnosis was reliable for carcinomas, chondrohartomas, and sarcomas, with limitations in low-grade mesenchymal tumors.
- Cytokeratin expression aided in thymoma and hyperplasia identification, while mammary lesion cytology accurately identified 94/97 carcinomas.
Impact:
- Intraoperative cytology provides prompt information essential for determining surgical scope.
- Histological examination complements cytology, especially for ambiguous or low-grade malignant tumors.
- This approach enhances diagnostic accuracy and optimizes patient management in surgical oncology.
