Hypothesis
This study aimed to correlate loss of Fhit protein expression with various molecular genetic and clinical parameters in non-small-cell lung cancers.
Conclusion
Loss of Fhit protein expression is a common abnormality in lung cancer that occurs independently of other molecular abnormalities.
Supporting Evidence
- 52 of 99 tumors lacked cytoplasmic Fhit staining.
- Lack of Fhit staining correlated with loss of heterozygosity at the FHIT 3p14.2 locus.
- Fhit expression was not correlated with survival or abnormalities of p53, RB, and p16.
Takeaway
The study found that many lung cancer tumors lose a protein called Fhit, which might be important for understanding how these cancers develop.
Methodology
The study used immunohistochemistry on paraffin sections of 99 non-small-cell carcinomas to assess Fhit protein expression.
Limitations
The study did not find a correlation between Fhit expression and various clinical parameters, including survival.
