Tumour token article multi-break point setting system used for optimizing rectal cancer diagnosis

Abstract

The invention discloses a setting system that is used for optimizing multiple tumor marker breakpoints in colorectal cancer diagnosis in the technical field of medicine and comprises a GUI module, a detected data storage module, a breakpoint generating module, a probability diagnosis module and an optimized setting module of the breakpoints. The GUI module is a graphic user interface, realizes the interactive operation between users and the system, and receives intermediate or final results of each module; the detected data storage module is used for storing two different data that are used in other modules in the system; the breakpoint generating module generates numerous setting schemes of the multiple breakpoints for each experimental combination group, and continuously optimizes the schemes in the information interaction with the probability diagnosis module. The probability diagnosis module evaluates the effects of each scheme, feedbacks the results to the breakpoint generating module, and finally stores the optimized schemes of each experimental combination group into the optimized setting module of the breakpoints, thus obtaining the optimal setting scheme of the breakpoints. The setting system can be directly used as an auxiliary decision making system in medical diagnosis.

Description

technical field [0001] The invention relates to a diagnostic device in the technical field of medical devices, in particular to a tumor marker multi-segment point setting system for optimizing the diagnosis of colorectal cancer. Background technique [0002] Colorectal cancer is a common malignant tumor. Its mortality rate ranks third among various tumors in the world, ranks second in the West, and ranks fourth in my country's incidence rate. In developed cities such as Shanghai, its incidence rate rose to No. 2. In recent years, more and more tumor markers have shown certain application value in the screening and auxiliary diagnosis of colorectal cancer. Many medical studies have explored the appropriate cutoff level between normal and abnormal values ​​of tumor markers, so as to improve the diagnostic effect. [0003] After searching the prior art documents, it was found that the article "Diagnostic Accuracy of Serum-carcinoembryonic Antigen in Recurrent Colorectal Cancer...

However, due to the wide range of tumor markers, their detection values ​​imply important information about the possibility of a patient's disease

For example, the CEA test results of two patients are 6 μg / L and 550 μg / L respectively. According to the conclusions of the above scholars, both of them can be considered as patients with colorectal cancer, but from the experience of doctors, the probability of two patients suffering from cancer is obvious. Different, even a patient with a CEA of 6 μg / L is likely to be benign, leading to misdiagnosis

Therefore, the diagnosis method of single cut-off point of tumor markers is too rough, and cannot quantitatively give the probability of cancer, and cannot maximize the diagnostic effect
