CD44 protein over-expression is associated with a poor prognosis of gastric cancer (GC) andprevious studies have shown that CD44 gene polymorphisms could affect survival and recurrence. In this study, wetested the hypothesis that polymorphisms impacting on the CD44 signaling pathway may predict clinical outcomes inpatients with GC. Materials and Methods: DNA was extracted from blood of 150 healthy individuals and formalin-fixedparaffin-embedded (FFPE) tumor tissue of 150 patients. The two polymorphisms rs187116 and rs7116432 werestudied by RFLP-PCR and sequencing techniques. Results: There was a strong significant correlation between singlenucleotide polymorphisms (SNPs) in the CD44 gene, tumor recurrence, and overall survival (p <0.0001). The existenceof a significant relationship between tumor recurrence and overall survival was proved in this study, with at least oneallele G for the polymorphism rs187116 and at least one allele A for polymorphism rs7116432. Conclusion: These resultsprovide evidence of a relationship between CD44 gene polymorphisms and clinical outcomes in our GC patients.This result could help identify individuals with GC who have a high risk of tumor recurrence.}, keywords = {Gastric cancer,CD44 gene,Single nucleotide polymorphism,RFLP-PCR}, url = {https://journal.waocp.org/article_60731.html}, eprint = {https://journal.waocp.org/article_60731_d038263dd8eaa9579d48ffdad581e042.pdf} }
