However, the expression and prognostic value of Lgr5 in recurrent nasopharyngeal carcinoma (rNPC) remains ambiguous.Materials: We used RNA sequencing to screen differentially expressed mRNAs in eleven specimens of rNPC tissues and five fresh adjacent normal tissue samples and the CSC marker, Lgr5, was identified. The expression level of Lgr5 in rNPC samples was also detected by immunohistochemistry and Western blot assay. The chi-square test was used to analyze the relationship between the clinicopathological variables and the immunostaining of Lgr5. The Log-rank method was used for prognosis analysis. The Cox regression model was used for univariate and multivariate analysis.Results: Significantly elevated expression of Lgr5 in the rNPC tissues was observed compared to the normal tissues using RNA sequencing, Western blot and immunohistochemistry. The expression of Lgr5 was significantly correlated with the T stage (P=0.014). High Lgr5 expression (P=0.007), tumor necrosis (P=0.013) and WHO type II (P=0.043) in rNPC patients exhibited worse overall survival (OS). Lgr5 expression was proved to be an independent risk factor for OS (P=0.035) in multivariate analyses, and had promising predictive value for survival and recurrence in rNPC patients (area under the ROC curve: 0.711 and 0.665, P=0.017 and 0.028, respectively).Conclusion: Lgr5 as a CSC marker is a promising therapeutic target and could be employed to predict the survival prognosis of rNPC patients.Keywords: recurrent nasopharyngeal carcinoma, cancer stem cell, Lgr5, survival |
