Abstract
Introduction
There are few known predictors of gastric cancer (GC). In this study, we evaluated the relationship between peripheral blood parameters and disease in patients with GC. Our aim was to identify a predictor of the development of metastasis.
Materials and Methods
Pretreatment peripheral blood parameters, including neutrophil, lymphocyte, and platelet counts; median platelet values (MPVs); and platelet distribution width (PDW), of patients diagnosed with GC were assessed. The independent T test was used in comparisons between two groups with a normal distribution, the Mann–Whitney U test in comparisons between two groups without a normal distribution, the Kruskal–Wallis test to compare more than two groups, and the Dunn’s multiple comparison test to compare subgroups. A p value <0.05 was considered statistically significant.
Results
In GC patients, neutrophil and platelet counts, but not lymphocyte counts and MPVs, increased significantly with disease stage progression. Among patients who developed a metastasis during follow-up, the relationship between PDW and the risk of metastasis was statistically significant (p = 0.04). Both lymphocyte and platelet levels had a statistically significant relationship to survival (p = 0.04 and p = 0.02, respectively).
Conclusions
Our results showed that in patients with GC, PDW, one of the standard parameters measured in a complete blood count, is a predictor of metastasis. Therefore, the PDW may be an important consideration in the surgical and chemotherapeutic treatment planning of patients with GC. Treatment strategies should also take into account lymphocyte and platelet levels, both of which were shown to be significantly related to survival.
