Problems solved by technology

However, due to the large differences in the physical and chemical properties of capecitabine and its metabolites, as well as the different levels in blood, the simultaneous detection technology is difficult. At present, there is no ultra-high performance liquid chromatography tandem mass spectrometry technology for the simultaneous detection of capecitabine in plasma. and its five metabolites reported in the literature

Abstract

The invention discloses a kit for simultaneously detecting capecitabine and its metabolites in plasma. Capecitabine and its metabolites are respectively: capecitabine, 5'-deoxy-5-fluorocytidine, 5 '-deoxy-5-fluorouridine, 2'-deoxy-5-fluorouridine, 5-fluorouracil, 5-fluoro-5,6-dihydrouracil; the simultaneous detection of capecitabine and its The kit for metabolites includes the following reagents: eluent, reference substance mother solution, mixed internal standard solution, diluent, extraction solution, and quality control solution. The invention also discloses an application of the kit for simultaneously detecting capecitabine and its metabolites in blood plasma in the preparation of hematological diagnosis or screening kits for malignant tumors. The kit for simultaneously detecting capecitabine and its metabolites in blood plasma of the present invention is used to simultaneously detect capecitabine and its metabolites, which has high sensitivity, strong specificity, high accuracy and simple pretreatment process.

Description

technical field [0001] The invention belongs to the technical field of blood quantitative detection, and specifically relates to a kit for simultaneously detecting capecitabine and its metabolites in blood plasma, a detection method and an application thereof. Background technique [0002] Since the early 1990s, cancer has become the number one cause of death in my country, among which malignant tumors of the digestive tract occupy the forefront of the morbidity and mortality of all malignant tumors, seriously endangering people's health and life [item] Yong Bing. The prevalence and current situation of malignant tumors of the digestive tract. Tumors, 2002,22(4):336-339.]. According to statistics, in 2013, there were about 1.05 million new patients with digestive tract malignant tumors nationwide, accounting for about 30% of the total incidence of malignant tumors, including about 420,000 new gastric cancer patients, 350,000 new colorectal cancer patients, 280,000 patients; ...
