Hypothesis
The study investigates the prognostic value of various pathological characteristics in resectable gastric cancer.
Conclusion
Tumor stage and eosinophilic infiltration significantly influence long-term survival in patients with resectable gastric cancer.
Supporting Evidence
- Univariate analysis showed significant impact of tumor stage and eosinophilic infiltration on survival.
- Multivariate analysis identified UICC clinical stage and eosinophilic infiltration as significant prognostic factors.
- Patients with numerous eosinophils had a lower risk of death compared to those with none.
Takeaway
This study found that certain tumor features can help predict how long patients with stomach cancer might live after surgery.
Methodology
The study performed univariate and multivariate analyses on data from 324 patients in a randomized surgical trial for gastric cancer.
Potential Biases
Potential bias due to the reliance on a single reference pathologist for the majority of tumor assessments.
Limitations
The study's findings may be limited by the subjective nature of eosinophil infiltration assessments and the small number of patients with high eosinophil counts.
Participant Demographics
Approximately two-thirds of the patients were male, and 40% were over 70 years old.
Statistical Information
Confidence Interval
95% CI 1.4–2.9 for stage II; 95% CI 2.5–4.8 for stage III; 95% CI 0.3–0.8 for eosinophils.
Statistical Significance
