Hypothesis
Is there a correlation between EGF receptor gene amplification and overexpression in squamous cell carcinomas of the head and neck?
Conclusion
The study found that gene amplification and overexpression of the EGF receptor are common in well differentiated squamous cell carcinomas of the head and neck.
Supporting Evidence
- 19% of squamous cell carcinomas showed EGF receptor gene amplification.
- 53% of squamous cell carcinomas examined had overexpression of the EGF receptor.
- All tumors with gene amplification also showed overexpression of the EGF receptor.
- Overexpression was statistically significant in well differentiated squamous cell carcinomas.
Takeaway
This study looked at tumors in the head and neck and found that some of them had more of a certain protein that helps cells grow, which might be important for understanding cancer.
Methodology
The study used Southern blot and Western blot analyses to examine gene amplification and protein expression in tumor samples.
Limitations
The study did not determine the clinical significance of EGF receptor overexpression.
Participant Demographics
The study included 40 patients with head and neck tumors, consisting of 30 malignant tumors and 8 benign tumors.
