Hypothesis

The expression dynamics of 14-3-3σ and its prognostic significance in gastric cancer are investigated.

Conclusion

High expression of 14-3-3σ is associated with poorer survival outcomes in gastric cancer patients.

Supporting Evidence

  • High expression of 14-3-3σ was significantly correlated with clinical stage and tumor invasion.
  • Elevated 14-3-3σ expression predicted poorer overall survival and progression-free survival.
  • 14-3-3σ expression was an independent prognostic parameter in gastric cancer.

Takeaway

This study found that a protein called 14-3-3σ is found in higher amounts in stomach cancer, and having more of it means patients might not live as long.

Methodology

Immunohistochemistry and Western blot were used to analyze 14-3-3σ expression in gastric cancer tissues, with ROC curve analysis for cutoff score determination.

Potential Biases

Potential biases in patient selection and retrospective analysis.

Limitations

The study was limited to a specific cohort of gastric cancer patients and may not generalize to all populations.

Participant Demographics

105 male and 47 female patients with a median age of 58 years.
