Abstract:
Objective To investigate the correlation between TIP 30 and VEGF-C expression and clini-cophathological characteristics in resected small cell lung cancer ( SCLC) patients and to identify patients with in-creased risk of cancer recurrence and to provide a theoretical basis for the further clinical prevention of SCLC . Methods Sixty eight resected SCLC patients were included in this study .Paraffin-embedded specimens of pa-tients were used for the evaluation of TIP 30 and VEGF-C expression by immunohistochemistry .Results The expression of VEGF-C had positive correlation with lymph node metastasis .TIP30 expression was positively cor-related with VEGF-C expression.Patients with low TIP30 expression had shorter Overall survival (OS)and Dis-ease-Free survival(DFS)than those with high TIP30 expression.OS and DFS of the patients with VEGF -C-positive tumors were significantly lower than that of the patients with VEGF -C negative tumors .The multivariate Cox regression analysis showed that low TIP 30 and high VEGF-C expression were independent markers of poor OS(P<0.01)in operable SCLC patients.Conclusion The expression of VEGF -C shows positive correlation with lymph node metastasis .Low TIP30 and high VEGF -C expression are independent prognostic markers of poor overall survival in resected SCLC patients .
