A MULTICENTER STUDY ON THE PREVALENCE AND PREVENTION OF ORAL CANCER

Background: To find out the incidence of science and cellular features of mouth cancer patients. Material and Method: Oral cancer cases diagnosed from 2018 to 2019, their biopsy records of the participated institution were reviewed. Site of lesions and analytical data were collected. Mandible and maxilla, palate, buccal/labial mucosa, alveolar mucosa, floor of the mouth, lip, tongue, were the subdivision of the site of lesions. Seven categories of oral cancer are: Salivary gland tumors, epithelial tumors, Hematologic tumors, Bone tumors, Odontogenic tumors and mesenchymal tumors. SPSS SOFTWARE and descriptive statistics were used for analyzing data. Results: Of the 474,850 assumed cases, 6150 cases [1.29%] were diagnosed with oral cancer. 58.36 ± 15.76 years was the mean age of the patients. A total of 4236 cases [68.80%] were diagnosed in males, whereas 1910 cases [31.06%] were diagnosed in females. The male to female ratio was 2.23:1.Alveolar mucosa, palate, gingiva, labial/buccal mucosa, are the sites of prepossession for oral cancer. In descending order of frequency the three most common oral cancer were Squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Conclusion: As compared to other, the prevalence of oral cancer is not high as compared to other entities, when discovered late in the course of disease, oral cancer pose significant mortality and morbidity in the patients. Anatomical locations where oral cancer are frequently encountered, are highlighted by this study. In the high prevalence area, clinicians should pay an attention to not only teeth but oral mucosa. The chance of patients being cured and great reduction in the mortality and morbidity increases when there is early detections of precancerous lesions in the early stage. Difference between pediatric and elderly oral cancer patients as well as between Asian and non- Asian oral cancer patients are also showed by this study.
