From 1984 to 1988, 62 fine-needle aspirations (FNA) were performed on palpable lesions in 59 gynecologic oncology patients at the UCLA Medical Center. Sites of aspiration included abdomen, cervix, vagina, superficial lymph nodes, and pelvic masses. Confirmatory open biopsy (41) or adequate clinical follow-up (17) was obtained in 55 patients (58 aspirates). FNA correctly established the diagnosis of malignancy in 19 of 26 (73%) biopsied patients. The predictive value for a positive test was 100%, and the predictive value for a negative test was 82%. Initial surgical biopsy had been incorrectly benign in 4 of these patients who were shown subsequently to have malignant tumors by FNA and clinical findings. In 7 patients, FNA failed to diagnose the malignancy found by open biopsy. Two of the false-negative FNAs were insufficient and five were in masses where palpation was inadequate. In 17 patients who were followed clinically without open biopsy, FNA correctly predicted the subsequent clinical course in 15 (88%). There were no false-positive FNA diagnoses obtained when cytologic results were correlated with both clinical outcome and surgical biopsy. Aspiration cytology has a specificity of 100% and a sensitivity of 65%. A negative FNA obtained from a clinically suspicious lesion should be followed by a repeat aspiration or surgical biopsy.
