Clinical Significance of WISP-1 and VEGF-A Expression Levels in Elderly Patients with Esophageal Squamous Cell Carcinoma
Objective To investigate the clinical value of WNT1 inducible signaling pathway protein 1(WISP-1)and vascular endothelial growth factor-A(VEGF-A)as novel molecular markers of esophageal squamous cell carcinoma(ESCC)in elderly patients.Methods Elderly patients with ESCC were divided into 65-70 years old group and>70 years old group.Immunohistochemical staining and RT-PCR were used to detect the expression levels of WISP-1 and VEGF-A proteins and mRNAs,respectively.Log rank test was used to analyze correlation between clinicopathological features and prognosis of ESCC in the elderly.Results The positive expression rate of WISP-1 in ESCC tissues was significantly higher than that in para-cancer tissues(53.33% vs.35.42%,P=0.045).The positive expression rate of WISP-1 in patients over 70 years old and with lymph node metastasis was significantly higher than that in patients aged 65-70 years and without lymph node metastasis(P=0.047 and 0.032).The positive expression rate of VEGF-A protein in ESCC tissues was significantly higher than that in para-cancer tissues(50.00% vs.20.83%,P=0.001).The positive expression rate of VEGF-A in patients with depth of infiltration T3-T4 stage,lymph node metastasis,and TNM Ⅲ-Ⅳ stage was significantly higher than that in patients with T1-T2 stage,no lymph node metastasis,andⅠ-Ⅱ stage(P=0.030,0.006,and 0.010,respectively).The mRNA expression levels of these two molecules were significantly higher in ESCC tissues than in para-cancer tissues(P<0.05),and the results of univariate analysis showed that the expression levels of WISP-1 and VEGF-A were correlated with the prognosis of ESCC in the elderly(P<0.05).The results of multivariate analysis showed that lymph node metastasis was the independent risk factor affecting the prognosis of elderly patients with ESCC.Conclusion WISP-1 and VEGF-A are associated with malignant behavior in elderly patients with ESCC.The expression of WISP-1 increased with age,and it has potential as a novel molecular marker of ESCC in elderly patients.
