Mammogram-directed fine-needle aspiration of nonpalpable breast lesions.
A prospective study was undertaken to evaluate the effectiveness of mammogram directed fine-needle aspiration cytology in women with nonpalpable abnormalities detected on mammogram. Seventy patients were entered into the research protocol, with 61 patients undergoing mammogram directed fine-needle aspiration. Forty-three of the aspirates were adequate for diagnosis. Fine-needle aspiration yielded an accurate diagnosis in 12 of the 14 carcinomas in which the sample was considered adequate, for a sensitivity of 87%. No patients were falsely diagnosed with malignant disease, a specificity of 100%. The predictive value of a positive test was 100%, and that of a negative test was 93%. We conclude that fine-needle aspiration cytology can aid in making a diagnosis when nonpalpable breast abnormalities are detected on mammogram.
