Popis: Aim and objectives The clinicopathologic parameters alone are not sufficient to precisely predict if oral potentially malignant disorders (OPMDs) remain unchanged, i.e., without any malignant changes, regress, or advance to oral squamous cell carcinomas (OSCC). Few of the OPMDs, with or without epithelial dysplasia, may transform to frank OSCC. Discovering various molecular markers that can predict OSCC transformation is essential to develop effective therapeutic strategies. GLUT-1 is one of the hypoxia as well as metabolic indicator markers that have been used to study the metabolic activity of the cells. Hence, given by the World Health Organization (WHO), GLUT-1 expression was studied in various grades of dysplasia to see whether it complements the WHO grading system (mild, moderate, and severe). Materials and methods The study was carried out on paraffin-embedded tissues of 10 normal oral mucosa and 30 OPMD cases. OPMD cases were classified into hyperkeratosis, mild dysplasia, moderate dysplasia, and severe dysplasia groups. Immunohistochemistry was carried out to evaluate the expression of GLUT-1 antigen. Results According to the WHO grading system of dysplasia, 11 (36.66%) cases were classified as hyperkeratosis, 9 (30%) cases were classified as mild dysplasia, 6 (20%) cases as moderate dysplasia, and 4 (13.33%) cases as severe dysplasia. There was a significant increase in GLUT-1 expression from normal to mild, moderate, and severe dysplasia (p value = 0.00). Conclusion The expression of GLUT-1 marker complements the WHO grading system of oral epithelial dysplasia. Clinical significance GLUT-1 expression can be used to complement the WHO grading system to grade epithelial dysplasia.
