Hypothesis
Is there a correlation between β2-microglobulin expression and survival in patients with oral cavity squamous cell carcinoma?
Conclusion
Elevated β2-microglobulin expression is associated with poor survival in patients with oral cavity squamous cell carcinoma.
Supporting Evidence
- Strong β2M expression was significantly correlated with advanced tumour stage.
- Patients with weak β2M expression had a 5-year survival rate of 92.4%, compared to 51.4% for those with strong expression.
- β2M expression was positively correlated with cell migration and invasion in oral cancer cell lines.
Takeaway
This study found that higher levels of a protein called β2-microglobulin in oral cancer patients mean they might not live as long.
Methodology
The study evaluated 256 samples from patients with oral cavity squamous cell carcinoma using immunohistochemical staining to assess β2-microglobulin expression.
Limitations
The study may not account for all variables affecting survival, and the sample may not represent all demographics.
Participant Demographics
The study included 239 men and 17 women with an average age of 50.9 years.
