Hypothesis
The study aims to identify potential candidate genes as prognostic markers in human oral tongue squamous cell carcinoma (SCC) through gene expression profiling.
Conclusion
The study identified GLUT3 and HSAL2 as significant predictors of prognosis in oral tongue carcinoma.
Supporting Evidence
- 77 genes were found to be differentially expressed in tongue tumor samples compared to matched normal controls.
- GLUT3 over-expression correlated with depth of invasion, tumor size, pathological stage, and recurrence.
- In survival studies, GLUT3 showed prognostic value with disease-free, relapse-free, and overall survival.
Takeaway
Researchers looked at genes in patients with tongue cancer to find out which ones might help predict how well someone will do after treatment.
Methodology
Gene expression profiles were analyzed using Affymetrix HG_U95Av2 arrays and validated with quantitative real-time RT-PCR.
Potential Biases
The heterogeneous nature of the samples may introduce bias.
Limitations
The study had a relatively small sample size and the findings may not be definitive.
