BACKGROUND: Colorectal cancer (CRC) mainly refers to colon and rectum cancer, which is the most common gastrointestinal malignant tumor. MicroRNAs (miRNAs) in tumors participate in multiple processes of malignancy development, including cell differentiation, proliferation, invasion, and metastasis. In this study we explored the relationship of miR-1260b abnormal expression with clinical pathological features in CRC patients.
MATERIAL AND METHODS: The expression of miR-1260b was detected by real-time quantitative polymerase chain reaction (real-time PCR) in 120 cases of CRC tissues. The correlation of miR-1260b expression with the clinicopathologic features of CRC was analyzed by SPSS 21.0 statistical software. The Kaplan-Meier method was used for survival analysis. Cox regression analyses were conducted to determine whether miR-1260b was an independent predictor of survival for CRC patients.
RESULTS: The miR-1260b expression in CRC was significantly higher than the expression levels in the corresponding para-carcinoma tissues (P<0.001). According to the expression levels of miR-1260b, 120 cases of CRC patients were classified into either the miR-1260b high expression group or the miR-1260b low expression group. The high expression levels of miR-1260b in CRC patients was associated with lymph node metastasis (P<0.05) and venous invasion (P<0.001). However, the high miR-1260b expression had no significant correlation with other clinical parameters (P>0.05). The high miR-1260b expression patients survived for shorter times than those CRC patients with low miR-1260b expression (P<0.05). Multivariate analysis revealed that high miR-1260b means poor prognosis of patients with CRC.
CONCLUSIONS: The high expression level of miR-1260b is an independent prognostic biomarker that indicates a worse prognosis for patients with CRC.
