Abstract:
Objective To investigate microRNA-217 expression and its significance in colorectal cancer.Methods MiR-217 expression was detected in 30 cases of colorectal cancer tissues and corresponding adjacent normal colorectal tissues by qRT-PCR.The clinicopathologic correlations of miR-217 expression were performed using Fisher's exact test.Kaplan-Meier method was used to evaluate the overall survival of patients.Results MiR-217 was significantly lower in colorectal cancer tissues than in normal colorectal tissues (P < 0.01).Moreover,the decreased miR-217 level was significantly associated with tumor size and TNM stage,as well as lymph node and distant metastasis.Meanwhile,patients of colorectal cancer with low levels of miR-217 expression had a significantly shorter median survival (x2 =4.584,P < 0.05) than those with high levels of miR-217 expression.Conclusions Downregulated miR-217 in colorectal cancer tissues correlates to poor prognosis in postoperative colorectal cancer patients.
