Hypothesis
The study aims to clarify the actual pattern of CD44 expression in head and neck epithelia.
Conclusion
CD44s and CD44v6 expression does not distinguish normal from benign or malignant epithelia of the head and neck.
Supporting Evidence
- CD44s and CD44v6 were expressed in 60–95% and 50–80% of cells in normal epithelia.
- In oral leukoplakia, CD44s and CD44v6 levels were slightly increased.
- Carcinomas in situ displayed unchanged levels of both proteins.
- Poorly differentiated carcinomas consistently expressed diminished CD44s and CD44v6 levels.
Takeaway
The study looked at how certain proteins are found in cells from the mouth and throat, and found that these proteins are present in many cells, whether they are healthy or cancerous.
Methodology
Expression of CD44s and CD44v6 was analyzed by immunohistochemistry in primary head and neck tissues.
Limitations
The study may not account for all variations in CD44 expression across different populations or cancer types.
Participant Demographics
Included samples from normal epithelia, oral leukoplakia, and various grades of carcinomas.
