Stratified sampling was executed to maintain a proportional representation of unilateral versus bilateral cases, leading to the creation of seven internal and three external datasets. Variable selection was performed using a decision tree-based recursive feature elimination method. We applied five-fold cross-validation on the internal datasets and conducted model testing on the external datasets. Four machine learning algorithms-random forest, extreme gradient boosting, logistic regression, and support vector machine-were used to build the predictive model and conduct external validation. Model efficacy was primarily appraised using the area under the receiver operating characteristic curve (AUC-ROC), calibration curves, decision curve analysis (DCA), and additional performance metrics including accuracy, precision, recall, and F1-score on the test set.

An increase in age and a more severe degree of hearing loss are risk factors for the occurrence of the disease, and females have a higher risk of disease occurrence. Other high-risk test indicators for disease occurrence can be summarized and categorized into two types of risk factors: lipoprotein dysfunction (total cholesterol, high-density lipoprotein cholesterol, apolipoprotein A1) and inflammation (eosinophils, lymphocyte count, neutrophil count).

This complex ecosystem, termed the tumor microenvironment (TME), includes recruited immune cells and the resident cells in the central nervous system. Glioma cells recruit myeloid cells and reprogram their phenotype to fuel tumor growth. Tumor cells and reprogrammed myeloid cells further suppress adaptive immune responses. Additionally, glioma co-opts normal brain cells-including endothelial cells, neurons, and astrocytes-to create a microenvironment favoring tumor progression. Following this phenotypic shift, normal cells synergize with tumor cells to drive proliferation, invasion, immunosuppression, and angiogenesis. This review integrates recent advances in understanding the multidimensional interactions within the glioma TME, including insights gained from single-cell and spatial transcriptomics approaches that reveal its heterogeneous architecture and functional niches.
