Federated Learning for Postoperative Segmentation of Treated glioblastoma (FL-PoST)

Announcement

Duke University, Indiana University, and the Response Assessment in Neuro-Oncology (RANO) team are excited to announce a new collaborative study seeking to extend the FeTS initiative to the post-operative/post-treatment setting using a large, diverse imaging dataset derived from patients with previously treated glioblastoma, which is hereby termed Federated Learning for Postoperative Segmentation of Treated glioblastoma (FL-PoST) or simply FeTS 2.0.

The FL-PoST initiative aims to revolutionize the quantification of brain tumors by establishing an international federation of healthcare institutions and developing an open-source software ecosystem that offers simple, automated, and accurate tumor segmentation free from inter-reader variability.

If you have previously been a part of the preoperative FeTS initiative, thank you for your continued interest and support! We hope that you will consider participating FL-PoST as well.

Purpose of the study

How to participate

  1. Identify a cohort of brain tumor MRI scans from your institution with a confirmed initial diagnosis of glioblastoma (this is the most important step and can start as soon as possible!).
  2. Identify relevant series (T1, T1+Gd, T2, T2-FLAIR) for each subject and their respective post-operative follow-up scans.
  3. Identify a “technical point of contact”, who will conduct the data processing and experiment from your end.
  4. Download and install the FeTS software (detailed instructions along with a new installer is coming soon!).
  5. Preprocess the MRI data using the FeTS software (detailed instructions along with a new installer is coming soon!).
  6. Generate automated segmentations using pre-trained models.
  7. Manually annotate and correct the automated tumor segmentations to generate ground truth labels using the tool of your choice (we recommend ITK-SNAP, CaPTk, or 3D-Slicer). Please ensure that the generated labels are silhouettes (i.e., the entire volume of the tumors are delineated) and not just boundaries.
  8. Run the federated training during the specified 2-week training window (to be announced).
