Abstract:
Objective:To detect the level of long non-coding RNA LINP1 (lncRNA-LINP1) in endometrial carcinoma and to explore the prognostic value of the expression leve.Methods:From January 2015 to December 2016, the tissue samples of 82 patients with endometrial carcinoma in North China University of Science and Technology Affiliated Hospital were used as endometrial carcinoma group, and the normal adjacent tissues were selected as the paracancerous control group.The expression of LINP1 mRNA was measured by real-time fluorescence quantitative PCR (qRT-PCR). The clinicopathological data of the patients were collected, and the relationship between the expression of LINP1 mRNA and clinicopathological parameters was analyzed.Kaplan-Meier method was used to analyze the relationship between the expression of LINP1 mRNA and the survival rate of endometrial patients; and COX multivariate analysis was used to identify the risk factors of death in patients with endometrial cancer.Results:The expression of LINP1 mRNA in endometrial carcinoma group and paracancerous control group were (2.38±0.43) and (1.00±0.24). There was significant difference between the two groups ( t=25.376, P<0.001). The results of clinicopathological parameters showed that the expression of LINP1 mRNA was not related to the age and histological type of endometrial carcinoma (all P>0.05). It was related to lymph node metastasis, FIGO stage, tumor differentiation and vascular invasion (all P<0.05). the three-year total survival rate of the group with high expression of LINP1 mRNA (48.78%) was lower than that of the group with low expression of LINP1 mRNA (80.49%), and the differences were statistically significant (χ 2=6.306, P<0.05). COX Regression analysis showed that, high expression of LINP1 mRNA and FIGO Stage III, IV and lymph node metastasis were the risk factors for death in endometrial cancer patients (HR(95% CI) were 2.898(2.031-4.136), 1.831(1.448-2.316), 1.708(1.364-2.138), P values were 0.002, 0.004 and 0.008, respectively. Conclusion:The high expression of LINP1 mRNA in endometrial carcinoma is closely related to lymph node metastasis, FIGO stage, tumor differentiation, vascular invasion and prognosis.It is a risk factor for the death of patients with endometrial cancer and may be used as an index to evaluate the prognosis of patients with endometrial cancer.
