Abstract:

Objective

To analyze the effect of the loss of expression of alpha-thulassemia/mental retardation syndrome X-linked gene (ATRX) on the prognosis of patients with gliomas, and to explore its correlation between glioma grade and glioma molecular marker isocitrate dehydrogenase (IDH) mutation.

Methods

The databases of PubMed, Medline, Web of Science, Ovid, Wanfang Medical Network, CNKI, etc. were retrieved by computer. The literatures on the relationship between the expression of ARTX and the prognosis and related indicators of glioma patients published at home and abroad from inception to June 2020 were collected. Meta-analysis was performed by Revman 5.3 computer software.

Results

A total of 18 literatures and 4593 patients were included. Among them, 8 articles reported the relationship between ATRX expression and the overall survival (OS) of glioma patients. The results showed that a loss of ATRX expression, and patients with glioma have a better prognosis (HR=0.55, 95%CI: 0.47-0.64, P<0.001); Five literature articles literatures reported the relationship between the expression of ATRX and disease-free survival (PFS) in patients with glioma. The results showed that ATRX was lost and the PFS of glioma patients was significantly prolonged (HR=0.57, 95%CI: 0.48-0.68, P<0.001); 11 included literatures reported the relationship between ATRX expression and glioma grade. The results showed that the expression of ATRX was significantly correlated with the grade of glioma, and the loss of ATRX was more likely to occur in low-grade gliomas (OR=2.11, 95%CI: 1.46-3.05, P<0.001); Seven included literature articles reported the relationship between ATRX expression and IDH mutation, with a total of 1987 patients. The results showed that ATRX loss was beneficial to IDH mutation (OR=13.97, 95%CI: 10.23-19.08, P<0.001).

Conclusion

The loss of ATRX indicates that patients with glioma have a better prognosis, which is closely related to tumor grade and IDH mutation.
