Multimodal brain tumor classification
This work addresses cancer diagnostics for medical professionals by improving tumor classification accuracy, though it appears incremental as it applies existing multimodal techniques to a specific dataset.
The paper tackled brain tumor classification by combining whole slide images and magnetic resonance images using a deep learning method, achieving cross-validation balanced-accuracy, kappa, and f1 scores of 0.913, 0.897, and 0.951, respectively.
Cancer is a complex disease that provides various types of information depending on the scale of observation. While most tumor diagnostics are performed by observing histopathological slides, radiology images should yield additional knowledge towards the efficacy of cancer diagnostics. This work investigates a deep learning method combining whole slide images and magnetic resonance images to classify tumors. In particular, our solution comprises a powerful, generic and modular architecture for whole slide image classification. Experiments are prospectively conducted on the 2020 Computational Precision Medicine challenge, in a 3-classes unbalanced classification task. We report cross-validation (resp. validation) balanced-accuracy, kappa and f1 of 0.913, 0.897 and 0.951 (resp. 0.91, 0.90 and 0.94). For research purposes, including reproducibility and direct performance comparisons, our finale submitted models are usable off-the-shelf in a Docker image available at https://hub.docker.com/repository/docker/marvinler/cpm_2020_marvinler.
