Long non‑coding RNA XIST predicting advanced clinical parameters in cancer: A Meta‑Analysis and... Dysregulated expression of long non‑coding RNA X‑inactive specific transcript (lncRNA‑XIST) has been indicated in various cancer types. In the present study, a meta‑analysis was conducted to evaluate the potential role of lncRNA‑XIST in predicting the clinicopathological parameters of patients with cancer. Eligible studies were obtained through a systematic search of PubMed, Web of Science, Embase and the Cochrane Library, of articles published prior to January 2019. The combined odds ratio and 95% confidence interval were calculated to determine the association between lncRNA‑XIST expression and patient outcome. In addition, 45 pairs of osteosarcoma (OS) tissues and adjacent healthy tissues from a single institution were analyzed for the expression of lncRNA‑XIST, and its association with clinicopathological features; ultimately, a total of 1,869 cancer patients from 25 studies were assessed. The results demonstrated that high expression levels of lncRNA‑XIST were significantly associated with lymphatic metastasis, larger tumor size, advanced cancer stage and distant metastasis.

In the OS patient cohort, it was demonstrated that lncRNA‑XIST was highly expressed in OS tissues, which negatively correlated with patient prognosis.

Abstract

Dysregulated expression of long non‑coding RNA X‑inactive specific transcript (lncRNA‑XIST) has been indicated in various cancer types. In the present study, a meta‑analysis was conducted to evaluate the potential role of lncRNA‑XIST in predicting the clinicopathological parameters of patients with cancer. Eligible studies were obtained through a systematic search of PubMed, Web of Science, Embase and the Cochrane Library, of articles published prior to January 2019. The combined odds ratio and 95% confidence interval were calculated to determine the association between lncRNA‑XIST expression and patient outcome. In addition, 45 pairs of osteosarcoma (OS) tissues and adjacent healthy tissues from a single institution were analyzed for the expression of lncRNA‑XIST, and its association with clinicopathological features; ultimately, a total of 1,869 cancer patients from 25 studies were assessed. The results demonstrated that high expression levels of lncRNA‑XIST were significantly associated with lymphatic metastasis, larger tumor size, advanced cancer stage and distant metastasis. However, sex was not associated with lncRNA‑XIST expression level. In the OS patient cohort, it was demonstrated that lncRNA‑XIST was highly expressed in OS tissues, which negatively correlated with patient prognosis. The present study indicated that lncRNA‑XIST may serve as a potential biomarker for advanced clinical parameters in human cancer.
