Tumor Segmentation is the task of identifying the spatial location of a tumor. It is a pixel-level prediction where each pixel is classified as a tumor or background. The most popular benchmark for this task is the BraTS dataset. The models are typically evaluated with the Dice Score metric.

A fast and accurate fully automatic method for brain tumor segmentation which is competitive both in terms of accuracy and speed compared to the state of the art, and introduces a novel cascaded architecture that allows the system to more accurately model local label dependencies.
A cascade of fully convolutional neural networks is proposed to segment multi-modal Magnetic Resonance images with brain tumor into background and three hierarchical regions: whole tumor, tumor core and enhancing tumor core to decompose the multi-class segmentation problem into a sequence of three binary segmentation problems according to the subregion hierarchy.
This paper presents the most recent effort on developing a robust segmentation algorithm in the form of a convolutional neural network that beats the current state of the art on BraTS 2015, is one of the leading methods on the BraTS 2017 validation set and achieves good Dice scores on the test set.
Due to a limited training dataset size, a variational auto-encoder branch is added to reconstruct the input image itself in order to regularize the shared decoder and impose additional constraints on its layers.
This work presents the KiTS19 challenge dataset: A collection of multi-phase CT imaging, segmentation masks, and comprehensive clinical outcomes for 300 patients who underwent nephrectomy for kidney tumors at the authors' center between 2010 and 2018.
A fully automatic way to quantify tumor imaging characteristics using deep learning-based segmentation and test whether these characteristics are predictive of tumor genomic subtypes is proposed.
Validations on further datasets show that CFCN-based semantic liver and lesion segmentation achieves Dice scores over 94% for liver with computation times below 100s per volume.
The 2019 Kidney and Kidney Tumor Segmentation challenge (KiTS19) was a competition held in conjunction with the 2019 International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) which sought to address issues and stimulate progress on this automatic segmentation problem.
By incorporating BraTS-specific modifications regarding postprocessing, region-based training, a more aggressive data augmentation as well as several minor modifications to the nnUNet pipeline, nnU-Net is able to improve its segmentation performance substantially.
Adding a benchmark result helps the community track progress.
