Intraoperative cytodiagnosis of lung tumors by needle aspiration.
Rapid-stain cytologic evaluation of needle aspirates are a recent adjunct to diagnosis and staging of lung neoplasms. The benefits of this approach include ease of sampling from deep and remote lesions and the fact that the results are generally available within 10 minutes. In the past 2 years, we did 187 needle aspirations for cytopathological evaluation in 70 patients at 51 thoracotomies and 21 mediastinoscopies. The cytologic findings from aspirates of lymph nodes, mediastinal masses, and intrapulmonary lesions were compared with diagnosis obtained by histopathological techniques. Quick-stain cytopathological evaluation discriminated cancer among all 55 lung masses from which aspirates were taken; specific diagnosis as to the type of neoplasm, lymphoproliferative disorder, or infection was achieved in 60 of 70 patients (85%). We conclude that intraoperative needle aspirations for cytologic evaluation facilitates the practice of modern general thoracic surgery.
