Abstract

Objectives: To evaluate the diagnostic value of fine-needle aspiration cytology in patients with breast tumors classified as BIRADS 4 and 5. Methods: A cross-sectional descriptive study was conducted on 104 patients who underwent fine-needle aspiration cytology and histopathology at Military Hospital 103 and Central Military Hospital 108 from January 2021 to September 2023. Cytology results were classified according to the Yokohama system and compared with histopathological results. Results: The mean age of the study group was 47.63 ± 15.61 years. The rates of cytology groups were: group I (inadequate): 0%, group II (benign): 36.5%, group III (atypical): 14.4%, group IV (suspicious for malignancy): 45.2%, group V (malignant): 3.8%. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cytology were 92.4%, 96.1%, 94.2%, 96.1%, and 92.4%, respectively. Conclusion: Diagnosis of fine needle aspiration cytology in patients with breast tumors with BIRADS 4 and 5 on ultrasound shows high sensitivity and specificity in diagnosis. This method is valuable in detecting malignant lesions in high-risk patients.
