Analysis of influencing factors of colorectal cancer based on nomogram
Objective To better identify the risk population of colorectal cancer by understanding the related influencing factors of colorectal cancer and constructing nomogram.Methods From October 2020 to March 2023,a total of 368 patients diagnosed with colorectal cancer in seven medical institutions in Sichuan Province were selected as the case group,and 380 general people in the same period were selected as the con-trol group.The questionnaire survey was conducted,and the related influencing factors of colorectal cancer were analyzed by multivariate logistic regression,and the nomogram of influencing factors of colorectal cancer was constructed.The model was verified internally,and its stability was evaluated.Results The results of multivariate logistic regression analysis showed that farmers (OR=3.527,95%CI:1.451-8.576),preference for animal oil (OR=3.789,95%CI:1.270-11.251),sugary drinks (OR=1.921,95%CI:1.200-3.075), and not taking calcium tablets (OR=2.011,95%CI:1.311-3.085) increased the risk of colorectal cancer;higher annual personal income (OR=0.482,95%CI:0.288-0.808;OR=0.126,95%CI:0.053-0.299),ab-sence of intestinal polyps (OR=0.169,95%CI:0.104-0.274),no heavy fatty foods (OR=0.432,95%CI:0.272-0.688),and light physical work (OR=0.220,95%CI:0.122-0.397) would reduce the risk of color-ectal cancer.The accuracy of nomogram was 74.3%,and the area under the receiver operating characteristic (ROC) curve was 0.836,the model had good discrimination and reliability.Conclusion The Nomogram can visualize influencing factors of colorectal cancer,which is beneficial to its prevention and treatment.
