Cancer stem cell (CSC) markers like CD44 and CD24 can predict oral squamous cell carcinoma (OSCC) patient outcomes. Specific immunophenotypes, particularly CD44 expression, offer valuable prognostic information for OSCC.
Area of Science:
- Oncology
- Cancer Research
- Immunohistochemistry
Background:
- Cancer stem cell (CSC) antigens are detectable in human tumors via immunostaining.
- Identifying CSC immunophenotypes is crucial for understanding tumor behavior.
Purpose of the Study:
- To identify a cancer stem cell (CSC) immunophenotype in oral squamous cell carcinoma (OSCC).
- To determine the prognostic influence of this CSC immunophenotype on OSCC patient survival.
Main Methods:
- Retrieved clinical data from 157 OSCC patients, including survival and risk factors.
- Conducted immunohistochemical analysis for CD44 and CD24 markers on OSCC tissue microarrays.
Main Results:
- Univariate analysis revealed significant associations between OSCC overall survival and alcohol intake, treatment, and CD44/CD24 immunophenotypes.
- Multivariate analysis confirmed the prognostic significance of these CD44 and CD24 expression patterns.
Conclusions:
- CD44 immunostaining, combined with the absence of CD24 immunoexpression, can enhance OSCC prognosis assessment.
- These CSC markers, alongside clinicopathologic data, improve the prediction of patient outcomes in OSCC.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
