Abstract: OBJECTIVE: To investigate expression of tripartite motif-containing 59 (TRIM59) in colorectal cancer and its correlation with clinicopathological features. METHODS: Colorectal cancers and adjacent tissues were collected; and expressions of TRIM59 were analyzed using real-time quantitative PCR(qPCR) and immunohistochemistry. Relationships between TRIM59 expressions and clinicopathological features and survival rates were analyzed. RESULTS: Results from the qPCR analyses on 86 cases of pair tissues showed that expression levels of TRIM59 in 20 cases were significantly higher than that in the paired adjacent tissues (t=12.86,P<0.01). Immunohistochemical results showed that positive expression rate of TRIM59 was 62.79% (54/86),which was significantly higher than 32% (37/86) in the adjacent tissues (χ2=6.74,P=0.009)。The high expression of TRIM59 was significantly correlated with TNM stages (χ2=8.515,P=0.003),tumor invasion depths (χ2=7.167,P=0.007) and lymph node metastases (χ2=5.511,P=0.018). Kaplan-Meier survival analyses showed that the overall survival (OS) and disease-free survival (DFS) of patients with high TRIM59 expression were significantly shorter than those of patients with low TRIM59 expression (P<0.05 both). CONCLUSION: TRIM59 was highly expressed in colorectal cancers and the high expressions were closely related to TNM stages,depth of invasions,lymph node metastases and prognosis.
