About

At present, chemotherapy is widely used in the adjuvant treatment of colorectal cancer patients after surgery. Capecitabine is one of the main chemotherapeutic drugs. But the effect is not good enough, the adverse reaction is serious, and the individual differences were significant. The present study shows that these problems are related to the differences in the exposure of capecitabine and its metabolites in different patients. The genetic biomarkers for capecitabine include DRD, MTHFR and TYMS. Mutations in these genes directly affect the expression of metabolic enzymes involved in capecitabine and control the concentration of capecitabine and its metabolites. However, these markers have been obtained through clinical trials in the United States, and their role in predicting the effectiveness or safety of capecitabine and its metabolites has not been validated in Chinese cancer patients.The study was based on a case study of patients with colorectal cancer in China, and capecitabine as the primary postoperative chemotherapy regimen to verify whether the available biomarkers can be used to predict the effectiveness and safety of capecitabine. To clarify the effect of capecitabine on endogenous metabolites, and to study the mechanism of its effect, so as to discover new biomarkers.
