Problems solved by technology

However, the occurrence and development of tumors is a very complicated process, and it is obviously impossible and unscientific to use the changes of a single molecular genetic marker to diagnose the disease
With the existing technical means, it is not possible to provide a more accurate early warning of tumor susceptibility only through genetic information, and the current early identification and prediction methods for tumors need to be improved

Description

technical field [0001] The present invention relates to the field of biomedicine. Specifically, it relates to a rectal adenocarcinoma susceptibility prediction kit and a rectal adenocarcinoma susceptibility prediction system. More specifically, the present invention relates to a kit for detecting STRs of genes related to susceptibility to rectal adenocarcinoma by means of short tandem repeats (Short tandem repeats, referred to as STR) site fragment analysis method, and by combining discriminant analysis statistical methods, thereby Early warning of susceptibility to rectal adenocarcinoma in subjects. Background technique [0002] Tumor is a disease closely related to genetics. To study the molecular genetic basis of tumors, and then propose tumor-specific genetic markers, it is hoped that it can be used for routine detection, clinical diagnosis, personalized treatment, and disease tracking after recovery. Etc. provides a simple and feasible method. However, the variabilit...
