Author: Edris, Ali Mahmoud M.; Ahmed, Hussain Gadelkarim; Mohammed, Elneel Ahmed
Abstract: Introduction: Early detection of a premalignant or malignant oral lesions promises to improve the survival and the morbidity of patients suffering from these conditions. Oral exfoliative cytology (OEC) is a non-invasive method that is well accepted by the patient, and is therefore, suitable for screening at-risk population for early diagnosis of oral cancer. Objective: The purpose of this study is to investigate the value of OEC in the detection of oral premalignant and malignant lesions. Material and methods: In this hospital-based case-control study, cytological scrapes from buccal mucosa were obtained from 100 individuals, of whom 50 were patients with oral lesions ascertained as “cases” and 50 were clinically healthy volunteers ascertained as “controls”. All patients with oral lesions were also subjected to oral biopsy and histological examination. Results: Out of 50 cases studied, histopathology showed the presence of: Oral squamous cell carcinoma OSCC (n = 28), leukoplakia (n = 8), dysplasia (n = 3), and benign normal lesions (n = 11). In cytology, a specificity of 100%, sensitivity of 93% and accuracy of 92% were obtained for OSCC. Leukoplakia gave a specificity of 100%, a sensitivity of 87.5%, and an accuracy of 95%. Conclusion: Despite the small number of cases in this study, OEC is a useful method for detecting oral premalignant and malignant lesions. OEC can detect a number of pathological conditions that require management.
