Decreased maspin combined with elevated vascular endothelial growth factor C is associated with poor prognosis in non-small cell lung cancer
Abstract
This study aimed to investigate the clinical significance of the combination of maspin and vascular endothelial growth factor (VEGF)-C expression in the prognosis of non-small cell lung cancer (NSCLC). Immunohistochemistry was performed to assay the expression of maspin and VEGF-C in primary tumor tissues, metastatic, and non-metastatic lymph nodes in 98 NSCLC patients. Survival analysis was determined by Kaplan-Meier curves. The positive expression rate of maspin was 26.5% (26/98) in NSCLC primary tumor tissues, significantly associated with histological type (P = 0.005) and the absence of nodal metastasis (P < 0.001). The expression of maspin in primary tumor tissues was stronger than metastatic lymph nodes of the N1 group (P = 0.048), while the metastatic lymph nodes of the N1 group had a stronger maspin expression than the N2 group (P = 0.008). In survival analysis, a positive expression of maspin of the N1 lymph node was also found to be an independent positive prognostic factor in overall survival (P = 0.003). We also found that decreased maspin combined with elevated VEGF-C is associated with a poor prognosis for disease-free survival (P = 0.019). Our results suggest that positive expression of maspin might significantly...Continue Reading
