Correlation of Ki-67 with Radiation Response and Grade in Meningiomas: A Systematic Review.
ABSTRACT
PURPOSE
This systematic review aimed to identify the role of Ki-67 as a prognostic factor in estimating tumor grade and the radiation response in meningiomas.
METHODS
A systematic search of the literature on meningiomas was carried out through the PubMed, Scopus, and EBSCOhost databases according to the PRISMA guidelines.
RESULTS
Our search resulted in 465 collected articles, 15 of which satisfied the eligibility criteria. Twelve studies reported the correlation between Ki-67 and meningioma grade. Two other investigations reported the relationship between Ki-67 and the radiation response in meningioma, and one failed to capture the association between Ki-67 and the radiation response in meningioma.
CONCLUSION
The Ki-67 proliferation index has a uniform correlation with meningioma grade. Two of the 3 studies on the correlation of Ki-67 with the radiation response in meningioma patients reported that patients with a higher Ki-67 responded better to radiation therapy.
