Next, nomograms that incorporated De Ritis ratio and significant clinicopathological features (age, gender, CEA, CA19-9, tumor location, pathological classification, differentiation degree, histological classification, TNM stage, tumor diameter, preoperative chemotherapy, and radiotherapy) were developed, which aimed to quantitatively predict the 1-, 3- and 5-year OS and DFS for the individual patient with stage II/III CRC (Fig. Nomograms to predict 1-, 3-, and 5-year overall survival for patients with colorectal cancer. Nomograms were performed by using significant clinicopathological features and De Ritis ratio to predict 1-, 3-, and 5-year overall survival Nomograms to predict 1-, 3-, and 5-year disease-free survival for patients with colorectal cancer. Nomograms were performed by using significant clinicopathological features and De Ritis ratio to predict 1-, 3-, and 5-year disease-free survival The calibration curves of the nomograms for predicting the probabilities of postoperative 3-year OS (Fig. In the training cohort, nomograms for predicting both OS and DFS had a stable prognostic performance at various follow-up times (Supplementary Table The clinical utility of the nomograms, TNM and AJCC system for predicting 5-year overall survival.
