CT scan images and their Dworak tumor regression grade can now be predicted in a more automated way by the use of customized random forests and give fairly good predictions (67% accuracy).

The Dworak tumor regression grade is a typical diagnostic tool to assess the tumor response of colorectal cancer patients. However, the Dworak grade is determined by a pathologist by inspection of the tumor biopsy without a dedicated measurement instrument. This work will further improve training and support for scoring the Dworak’s in a more correct manner.
