Abstract
Brain tumors killed roughly 250,000 people worldwide in 2020, with approximately 300,000 new diagnoses that same year. The most aggressive type, Glioblastoma Multiforme (GBM), carries a median survival of just 15 months and a five-year survival rate under 5%. A key clinical complication is the MGMT gene promoter: its methylation status determines how well a patient respond to chemotherapy, but establishing it currently requires an invasive biopsy. This paper proposes a non-invasive framework combining 3D U-Net MRI segmentation with a soft-vote hybrid classifier (KNN + GBC). On the RSNA-MICCAI dataset (585 samples), 3D U-Net segmentation yields 111 volumetric radiomic features versus 54 from a 2D U-Net. The hybrid model achieves 99.4% classification accuracy on the richer 3D features, well above deep learning baselines (39–49%) tested on the same data, confirming that feature quality and ensemble diversity outperform model complexity on small clinical datasets.
