abstract = {Identifying radiomics features that help predict whether
glioblastoma patients are prone to developing epilepsy may
contribute to an improvement of preventive treatment and a
better understanding of the underlying pathophysiology.In
this retrospective study, 3-T MRI data of 451 pretreatment
glioblastoma patients (mean age: 61.2 ± 11.8 years; 268
men, 183 women) were analyzed. Three hundred thirty-six
patients reported no epilepsy, while 115 patients were
diagnosed with symptomatic epilepsy. A total of 1,546
radiomics features were extracted from contrast-enhancing
tumor, peritumoral regions, and normal-appearing white
matter as regions of interest using PyRadiomics. The dataset
was initially split into a training $(70\%)$ and a
validation $(30\%)$ cohort. The training cohort was used for
feature selection with ElasticNet and model optimization.
Various machine learning models, including logistic
regression (LR), were used to predict epilepsy status. The
models' performances were evaluated with the validation
cohort, and the area under the curve of the receiver
operating characteristics (AUC) was used as a measure. For
identifying relevant features, permutation feature
importance was applied.The performance of LR using radiomics
features from only a single ROI in the validation cohort was
AUC = 0.83 $(95\%$ CI: 0.76-0.91) and AUC = 0.77 $(95\%$ CI:
0.69-0.85) for the peritumoral and white matter regions,
respectively. The most important features in peritumoral
regions were shape features, while for the white matter
region, higher-order features from FLAIR were most
relevant.Radiomics features from peritumoral and
normal-appearing white matter can be associated with
epilepsy status at diagnosis, suggesting an important role
of these regions for the development of epilepsy in
glioblastoma patients.},
