The CAMELYON16 challenge has ended in November 2016




The goal of this challenge is to evaluate new and existing algorithms for automated detection of metastases in hematoxylin and eosin (H&E) stained whole-slide images of lymph node sections. This task has a high clinical relevance but requires large amounts of reading time from pathologists. Therefore, a successful solution would hold great promise to reduce the workload of the pathologists while at the same time reduce the subjectivity in diagnosis. This will be the first challenge using whole-slide images in histopathology. The challenge will run for two years. The 2016 challenge will focus on sentinel lymph nodes of breast cancer patients and will provide a large dataset from both the Radboud University Medical Center (Nijmegen, the Netherlands), as well as the University Medical Center Utrecht (Utrecht, the Netherlands).
