Abstract Objective To improve the early diagnostic rate of colorectal cancer in order to have colorectal cancer patients diagnosed as early as possible for the best treatment result. Methods Based on the Machine Learning theory and practices, the forward method was adopted inlogistic regression(LR)in order to analyze and screen the serum marker of the best referential value. Support Vector Machine (SVM)and Back Propagation (BP)were used to establish an early diagnostic model for colorectal cancer. Results The experiment results showed that such serum markers as CEA、CA1724、CA242、CA153 and HSP60 were of diagnostic valuefor colorectal cancer. The LR colorectal cancer diagnostic model that combined the above mentioned five types of serum markers outperformed that of each individual serum marker. Conclusion Combined tests can enhance the detection sensitivity to colorectal cancer. The LR colorectal cancer diagnostic model has a higher diagnostic value than the model based on SVM.
