ABSTRACT
Objective To investigate the mechanism of the fluorouracil(FU)drug resistance and to prove deeply the role of serum dihydropyrimidine dehydrogenase(DPD)activity in patients with gastric cancer resistance to FU with the level of cell culture. Methods The peripheral blood was collected from 45 patients with advanced gastric cancer before chemotherapy to detect the activity of DPD by high performance liquid chromatography(HPLC).The patients were divided into two groups(high activity group and low activity group)according to the results. The FU drug inhibitory rate of gastric cancer cell cultured in vitro were tested with MTT to compare the effects of the two groups. Result The FU drug inhibitory rate of gastric cancer cell cultured in vitro was obviously lower in high activity group than that in low activity group,(47.6±±4.0)%,(53.7±8.0)%respectively. Conclusion The activity of serum DPD may be simple and convenient indicators in predicting the resistance to FU.
