Task: Multi-class tumor segmentation (necrotic core, enhancing tumor, edema) on brain MRI (T1, T1c, T2, FLAIR) + primary tumor origin classification (binary: NSCLC vs Breast carcinoma)
Note: The classification head outputs 3 classes (0: NSCLC, 1: Breast carcinoma, 2: Other origin — present in the full training cohort but excluded from this public dataset). Since no label-2 cases appear in the public split, AUROC/AUPRC are computed as binary using the class-1 (Breast carcinoma) probability against class-0 (NSCLC).
