Abstrakt: Objective: To test the efficacy of exfoliative cytology in the detection of oral premalignant and malignant lesions.
Design: Cytological diagnosis of lesions of the buccal mucosa assessed using histopathological diagnosis of the same lesions as the gold standard.
Subjects: Patients with buccal lesions clinically diagnosed as leukoplakia (n = 91) and squamous cell carcinoma (SCC, n = 59), and healthy subjects (n = 40) in whom buccal mucosa appeared clinically normal.
Setting: Oral and Maxillo-facial Unit, General Hospital, Kandy and Department of Pathology, Faculty of Medicine, University of Peradeniya.
Results: A sensitivity of 77%, specificity of 100% and accuracy of 92% were obtained for leukoplakia. SCC gave a sensitivity of 94%, specificity of 100% and an accuracy of 95%.
Conclusions: Oral exfoliative cytology is a useful method for detecting oral premalignant and malignant lesions. Anucleated squames in a smear is non-diagnostic.
