Xinhua News Agency, London, March 17 (Reporter Liu Shilei) A recent study in the UK said that researchers have developed a new method to determine the risk of stomach cancer and esophageal cancer through urine tests, which will help More convenient early diagnosis.
Researchers at Imperial College of the United Kingdom have published relevant reports in the new American academic journal Chemistry and Engineering News. The researchers said they selected three volunteer groups, a group of 17 patients with gastric cancer, esophageal cancer, a group of 13 healthy people and a group of 14 patients with non-cancerous upper gastrointestinal diseases, and compared each A 10 ml urine sample of the group of subjects.
The researchers analyzed the volatiles of the samples by chemical mass spectrometry and found that the contents of seven compounds such as acetaldehyde, hydrogen sulfide and caproic acid in the urine samples of cancer patients were significantly different from those of the other two groups. The researchers said that data analysis showed that the comprehensive detection results of the concentration of six compounds can clearly determine the risk of gastric cancer in the subjects.
Dr. Huang Juzheng, one of the leaders of the study and a Chinese researcher at Imperial College of Science and Technology, said in an interview with Xinhua News Agency that previous studies have shown that the concentration of compounds such as acetaldehyde in gastric juice is related to cancer risk, but sufficient amount is taken from patients. Gastric juice is difficult and cannot be used as a clinical diagnosis method, and urine detection is obviously simpler and more convenient.
According to reports, there are more than one million cases of gastric cancer esophageal cancer in the world every year. However, because the early symptoms of these cancers are not obvious, less than 20% of patients can be diagnosed and treated before the cancer enters advanced stage. This is also the current mortality rate of gastric cancer in esophageal cancer. One of the reasons for the high.
