IMC Brain Tumors dataset (Karimi et al.)

The brain tumor IMC dataset profiles the brain tumors microenvironment from 139 patients with primary glioblastoma (GBM) and 46 individuals with metastatic brain tumors (BrM). For each sample, we considered 18 common channels (17 protein markers) that were shared across samples. The samples were obtained across the brain tumors microenvironments, including tumor core, invasive margin, and adjacent non-malignant tissue compartments. Because certain patients contributed multiple spatial regions, the dataset includes 270 GBM samples and 123 BrM samples. In classification experiments, we sought to classify patients with glioblastoma from those with metastatic brain tumors.
