ABSTRACT
Objective:
To explore the prognostic value of poliovirus receptor(PVR) in patients with gastric cancer.Methods:
Bioinformatics methods were used to analyze the expression of PVR mRNA in gastric cancer tissues and adjacent normal tissues and its relationship with prognosis. The clinicopathological data of 73 gastric cancer patients who underwent surgical treatment were retrospectively analyzed. Immunohistochemical method was used to detect the expression level of PVR in gastric cancer tissue and adjacent normal tissue, and its relationship with the clinicopathological characteristics of gastric cancer patients was analyzed.Results:
The expression level of PVR mRNA in gastric cancer tissues was higher than that in adjacent normal tissues ( P<0.05). The expression of PVR is related to the clinical prognosis of gastric cancer patients, and the higher the expression of PVR, the lower the overall survival rate ( P=0.011) and the disease-free survival rate ( P=0.032) of gastric cancer patients. The results of immunohistochemical staining showed that PVR was highly expressed in gastric cancer tissue, mainly in the cytoplasm, while it was not expressed or lowly expressed in normal gastric tissue. High expression of PVR was associated with tumor size ( P=0.001) and recurrence 3-years after surgery ( P=0.013).Conclusions:
PVR is overexpressed in gastric cancer tissue, and gastric cancer patients with high expression of PVR have a worse prognosis. The level of PVR has great value for the prognosis evaluation of gastric cancer patients.
