Abstract
Transthoracic fine needle aspiration-specimens with abnormal cytology were obtained from 272 patients. A comparison was made between the original specific cytologic and final histologic diagnoses on 116 patients; an additional 16 patients with the cytologic diagnosis of small-cell carcinoma were evaluated by clinical criteria. Analysis of the data indicated that malignant neoplasms were identified correctly with an accuracy of 99%. There was a single false-positive diagnosis. Predictive values for a specific morphologic variant of pulmonary neoplasm were 70% for squamous-cell carcinoma, 86% for adenocarcinoma and 95% for small-cell carcinoma. The probable bases for diagnostic error are discussed. Confidence intervals calculated from these data compared favorably with those in recently reported studies. The value of fine needle aspiration cytopathology for the diagnosis of pulmonary neoplasms is reconfirmed.
