We have started planning the logistics for the hackathon. Please fill in this survey to inform us about your participation plans.

We are glad to announce that the LYSTO Hackathon will be sponsored by NVIDIA, who will offer a Titan V GPU to the winner of the challenge.

Lymphocyte Assessment Hackathon

The LYmphocyte aSsessmenT hackathOn (LYSTO) is a challenge on the assessment of lymphocytes  in immunohistochemically stained tissue sections organized in conjunction with the COMPAY 2019 workshop.

The goal of this hackathon is two-fold:

  • Develop and compare solutions for a clinically relevant task in the typical medical image analysis challenge setting.
  • Facilitate interaction and teamwork between researchers with different levels of experience.

The task of the hackathon will be the automatic assessment of lymphocytes in tissue sections of several types of cancer  in human specimens stained with CD3 and CD8 immunohistochemistry. This is an important component of prognostic markers that are likely to be adopted in routine diagnostics in the near future. As an example, in the field of colorectal carcinoma, a prognostic marker based on such quantification already exists and is known as Immunoscore.

While the task has high clinical relevance, we believe that, with the help of artificial intelligence methods, accurate solutions can be developed in a short amount of time, making it ideal for a hackathon event.

The first part of LYSTO 2019 will follow a typical medical image analysis challenge format:

  • A small training and test set will be released on this website.
  • Researchers that are interested in participating in the challenge will be able to register and use an initial, smaller dataset to get familiar with the task and develop pilot methods.
  • Two weeks before the workshop date the full training dataset will be released. 
  • One week before the workshop, the challenge will be closed for new registrations.

The hackathon will run in parallel with the COMPAY19 workshop on October 13, in conjunction with the MICCAI 2019 conference in Shenzhen (China). In order to compete in the hackathon, participants must attend the COMPAY19 workshop, as the final test set will be released during that workshop event.

The organizers of LYSTO will facilitate the creation of teams of researchers that will participate together. During the hackathon event that will run in parallel with the workshop, the teams can work together on joint solutions.

All methods developed during the hackathon will be summarized in a journal publication that will be submitted to a high-impact journal. 


A Forum section is available on this site, which should be used for questions and discussion about the LYSTO challenge. For other questions, you can contact Dr. Francesco Ciompi.

Hackathon timeline:

  • Small (pilot) dataset released: August 6, 2019
  • Automatic evaluation of pilot test set released: Beginning of September, 2019.
  • Full training dataset released: October 1, 2019
  • Closed for new registrations: October 6, 2019
  • Teams of participants formed/method development in teams: October 6 - October 13, 2019
  • Full test set (on site) release/hackathon (parallel with the COMPAY workshop): October 13, 2019

More detailed information will be added to this website in upcoming weeks.

Stay tuned!
