| Research Abstract |
The present study aimed to develop a clinical-pathological interactive diagnosis system, where we intend to correlate macroscopic mucosal changes with intraepithelial phenotypic alterations. To this goal, the degree of intraepithelial malignancy is classified into 4 grades, depending on CK13 down-expression and Ki-67 localization. The immunohistology-based 3D reconstruction helped to elucidate intraepithelial alterations taking place with premalignant to malignant transition and to assess quantitatively the number and size of cell clusters possessing discrete differentiation/proliferation phenotypes. The 3D analyses also delineated architectural abnormalities associated with the dysplasia-invasion transition. The present immunophenotypic evaluation disclosed complicated distribution of epithelial phenotypes and the degree of proliferative capacity in oral epithelial lesions.
