PURPOSE: To investigate the expression of thrombospondin 2 (THBS2) in colorectal cancer (CRC) and its relationship with clinicopathological features and prognosis. METHODS: THBS2 expression was evaluated with tissue microarrays (TMAs) immunohistochemistry (IHC) staining in 100 CRC samples. RESULTS: High THBS2 expression was found in 73 patients (45 male and 28 female). THBS2 expression was significantly correlated to TNM stages (p=4.1×10-5), T classification (p=0.005), lymph node metastasis (p=3×10-4) and AJCC stages (p=0), while no significant association was found in gender, age, distant metastasis or tumor size. In both univariate and multivariate analyses, THBS2 showed statistically prognostic significance [p<0.001, HR (hazard ratio) = 0.237, 95% CI (0.101-0.557) and p<0.001, HR=0.158, 95% CI (0.062-0.401)]. Kaplan-Meier survival analysis further confirmed that THBS2 expression was significantly correlated with clinical outcomes (p<0.001). CONCLUSIONS: All the results indicated THBS2 expression might become a prognostic marker for CRC.
