Welcome to the THUNDER portal

Acronym for: THeragnostic Utilities for Neoplastic DisEases of the Rectum


In this study treatment response is predicted for rectal cancer patients using PETCT imaging. Currently used outcome is pathologic complete response, based on ypTN and TRG. Machine learning classification techniques as well as traditional statistical methods are used to separate data into responders and non-responders. Currently a multi-centric prospective study is carried out with the aim of validation and improvement of retrospective data based models.

This portal can be used to share data between institutes. This data consists of repeated PETCT scans for rectal cancer patients and phantom measurements to calibrate tumor contouring.
