Reliability of cytologic typing of lung cancer.
In a prospective study of 111 cases of lung cancer, cytopathologic diagnoses were compared with histologic diagnoses. In 77.5 per cent of the cases, histopathologic diagnoses were in concurrence with cytopathologic diagnoses. The discrepancies occurred mainly in poorly differentiated adeno and  epidermoid carcinoma. Well differentiated adeno and epidermoid carcinoma were cell typed with 100 per cent accuracy and small cell carcinoma with 90 per cent accuracy.
