Background And Purpose

To summarize the predictive value of MRI for H3 K27M-mutant in midline gliomas using meta-analysis

Method

Systematic electronic searches of the PubMed, Embase, ISI Web of Science, and Cochrane Library up to Jun 31, 2021, were conducted by two experienced neuroradiologists with the keywords of “MRI,” “Glioma,” and “H3 K27M.” The hierarchical summary receiver-operating characteristic (HSROC) model was used to calculate the pooled sensitivity, specifcity, positive likelihood ratio (LR+), negative likelihood ratio (LR−), and diagnostic odds ratio (DOR). Coupled forest plots were used to evaluate the heterogeneity of the included studies.

Conclusion

This meta-analysis demonstrated a clinical value of MRI to predict H3 K27M-mutant in midline gliomas with a pooled sensitivity of 0.78 and specifcity of 0.85.

Main results

Of seven original studies with a total of 593 patients, 240 glioma patients were included, with 45.5–70.6% H3 K27Mmutant gliomas. Using MRI, a pooled sensitivity of 0.78 (95% CI, 0.66–0.87), specifcity of 0.85 (95% CI, 0.76–0.91), LR+of 5.07 (95% CI, 3.19–8.08), LR−of 0.26 (95% CI, 0.16–0.42), and DOR of 19.80 (95% CI, 9.28–42.28) were achieved for H3 K27M-mutant prediction. Signifcant heterogeneity was observed among the studies in terms of sensitivity (Q=16.83, df=7, p=0.02; I2=58.40 [95% CI, 25.83–90.97]), LR−(Q=16.61, df=7, p=0.02; I2=57.87 [95% CI, 24.81–90.93]), and DOR (Q=14.05, df=7, p=0.05; I2=50.18 [95% CI, 10.06–90.31]).
