[0126] Using the physical examination data of a hospital of the People's Liberation Army in 2017 (the total number of samples is 10639), of which 130 were in the positive group and 10,509 in the negative group (in line with the true ratio, which improved the scalability of the regression model and the practical significance of the risk evaluation method in this application), based on this application modeling method. The final prediction model included age class and 11 biomarkers or blood indicators as independent variables: cytoplasmic thymidine kinase 1 concentration (TK1), lymphocyte count, mean corpuscular volume, platelet count, leukoglobulin ratio, serum Albumin, aspartate aminotransferase, creatinine, urea creatinine, alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA).
[0127] Among them, the age grade value can be preset as: 20-29 years old is assigned as 1, 30-39 years old is assigned as 2, 40-49 years old is assigned as 3, 50-59 years old is assigned as 4, 6...
