Hypothesis
What is the prognostic impact of NF-κB p105, vimentin, E-cadherin, and Par6 expression in non-small-cell lung cancer?
Conclusion
High expression of NF-κB p105 and low expression of vimentin in tumor epithelial cells are independent predictors of better survival in primary non-small-cell lung cancer.
Supporting Evidence
- High tumor epithelial cell expressions of NF-κB p105 and E-cadherin were positive prognostic indicators for disease-specific survival.
- High tumor epithelial cell expression of vimentin was a negative prognostic indicator.
- High expression of NF-κB p105 and Par6 in the stromal compartment correlated with a good prognosis.
Takeaway
This study looked at how certain proteins in lung cancer cells can help predict how well patients will do. Some proteins are good signs, while others are bad signs for survival.
Methodology
Tissue microarrays were constructed from tumor samples and evaluated using immunohistochemistry to assess the expression of various molecular markers.
Potential Biases
Potential biases may arise from the retrospective nature of the study and the reliance on immunohistochemical staining.
Limitations
The study was retrospective and may have biases related to the selection of patients and the analysis of tissue samples.
Participant Demographics
The median age of participants was 67 years, with 75% being male.
