Abstract:

AIM: To investigate the relationship of Syndecan-1 and EGFR expression, K-Ras gene mutations and response to FOLFOX in advanced colorectal carcinoma.  METHODS: 160 surgical specimens of advanced colorectal carcinoma from patients consecutively treated between June 2009 and December 2014 at our hospital were collected. Immunohistochemistry method was used to screen for Syndecan-1 expression. The relationship between Syndecan-1 expression and various clinicopathological parameters, molecular markers, curative effect of FOLFOX was analyzed.RESULTS:Syndecan-1 expression was identified in the cancer cells of 41 (25.6%) colorectal cancer cases, epidermal growth factor receptor expression in 111(69.4%) colorectal cancer cases. The expression of syndecan-1 was statistically correlated with the expression of epidermal growth factor receptor (P<0.05). However, it was not significantly correlated with K-Ras mutation (P>0.05). Patients with over-expressed Syndecan-1 exhibited better efficacy on FOLFOX solution than patients presented negative Syndecan-1 expression (56.1% vs. 40.3%, P<0.05);  Patients with over-expressed Syndecan-1 also presented longer median time to progress (8.8 month vs. 7.2 month, P<0.05). CONCLUSION: The expression of Syndecan-1 is referential for evaluating the progress and the prognosis of colorectal cancer. And the expression of Syndecan-1 is statistically correlated with curative effect of FOLFOX regimens.
