RÉSUMÉ
Introduction and Objective : The aim of this study was to assess the cytological changes in oral epithelium that might be induced by Sudanese homemade alcoholic beverages. Material and methods: Oral Exfoliative Cytology (OEFC) was applied to a case control study to assess the presence and severity of oral epithelial atypia (ET) in 300 subjects (150 alcohol abuse individuals (cases); 150 non-alcohol abuse individuals (controls)). All cases were using homemade alcoholic drinks, locally known as, Aragee, Marisa and others. Five patients with oral squamous cell carcinoma (OSCCs) were included as internal controls. Results: ET was detected in 7 subjects and was not observed in the remaining 293. All the 7 subjects with cytological atypia were cases. Cytological atypia were identified among those using Aragee, Marisa, and Aragee & Marisa together, representing 53%, 28.6%, 18%.4, respectively. Cytological atypia was found in all the 5 control cases with OSCCs. For the cytological atypia among alcohol abuse individuals, the adjusted OR and the 95% CI were found to be 5 (4.34-5.84) and P = 0.008. Inflammatory cells infiltrates were identified among 21 (14%) of the cases and only 12 (8%) of the controls and the adjusted OR and the 95% CI were found to be 5 (2.51-11.21) and P = 0.009. Conclusion: In view of these findings, Sudanese homemade alcoholic beverages cause oral epithelial atypical changes, which lead to oral precancerous and cancerous lesions. OEFC is a useful procedure for detection and assessment of oral ET.
RÉSUMÉ
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.
