Fine-needle aspiration cytology in gynecologic oncology. I. Diagnostic accuracy

A prospective study was undertaken to determine the diagnostic accuracy of fine-needle aspiration (FNA) cytology in gynecology. A total of 77 aspirations were performed on 74 patients. In 34 instances the purpose was to rule out or confirm a diagnosis of primary disease, and in 43 cases the procedure was used for suspected metastatic disease or disease recurrent after surgery, radiation therapy, and/or chemotherapy. Excellent correlation was noted between the cytologic and subsequent histopathologic diagnoses of 58 aspirations from patients who also underwent surgical biopsy. Two specimens were false negatives as the result of sampling errors. The applicability of FNA cytology in the field of gynecolotic oncology is discussed.
