Summary of DALEX method results. Degree of importance of the clinical, biological, and genetic characteristics previously selected by the five algorithms that contributed the most to predicting the Dworak grade of tumor regression after RCT was administered before surgery. The variables are arranged in order of increasing importance. The results show that chromosomal alterations in 4q, 15q14, and 15q11.1 are the most important variables for predicting the response to preoperative RCT in patients with locally advanced rectal cancer.
