Summary
Oral squamous cell carcinoma malignancy grading correlates with vimentin expression. Vimentin was highly expressed in aggressive tumors, suggesting its role in oral cancer progression.
Area of Science:
- Oncology
- Pathology
- Biomarkers
Background:
- Oral squamous cell carcinoma (OSCC) is a common malignancy.
- Histological grading is crucial for OSCC prognosis.
- Vimentin and cytokeratin are intermediate filament proteins with roles in cell structure and motility.
Purpose of the Study:
- To investigate the relationship between histological malignancy grade and the expression of vimentin and cytokeratin in OSCC.
- To determine if vimentin or cytokeratin expression can serve as a prognostic marker in OSCC.
Main Methods:
- Immunohistochemical analysis of 43 OSCC cases.
- Avidin-biotin method for anti-vimentin antibody.
- Peroxidase anti-peroxidase method for anti-cytokeratin antibody.
- Classification of tumors using Anneroth's histological malignancy grading system.
Main Results:
- All OSCC cases expressed cytokeratin.
- Vimentin was expressed in 60.4% of the cases.
- Vimentin expression was significantly higher in tumors with higher malignancy grades, particularly in those with highly malignant cells.
Conclusions:
- Cytokeratin is universally expressed in OSCC.
- Vimentin expression is associated with advanced histological grade and higher malignancy in OSCC.
- Vimentin may be a potential biomarker for aggressive OSCC.
