Objective To detect the expression of IL-17 and STAT3 in colorectal cancer (CRC) tissue and explore their relation with its clinicopathological features and angiogenesis. Methods Expression of IL-17 and STAT3 in 94 CRC tissue samples and 31 normal intestinal mucosa tissue samples was detected by immunohistochemistry SP method and microvessel density (MVD) was counted according to the number of CD34- marked microvessels. Results Immunohistochemistry showed that the IL-17 was mainly expressed in cytoplasm and lymphocytes of normal intestinal mucosa tissue samples
and its positive expression rate was significantly higher in CRC tissue samples than in normal intestinal mucosa samples (P0.01 ). The expression of IL-17 was related with the CRC cell differentiation and Dukes stage (P0.05 ). The expression level of STAT3 was significantly higher in CRC tissue samples than in its adjacent normal tissue samples ( P0.01 )
which was related to the CRC cell differentiation
lymphatic metastasis and Dukes stage (P0.05). The expression of IL-17 and STAT3 in CRC tissue samples was related with MVD (P0.05). Spearman stage correlation analysis showed that the expression of IL-17 was positively related with that of STAT3 in CRC tissue samples (r=0.251
P=0.015). Conclusion Over-expression of IL-17 and STAT3 in CRC tissue may play an important role in the angiogenesis and carcinogenesis of CRC.
