According to British media reports on March 6, scientists from China and Israel recently researched a new method for the diagnosis of gastric cancer, which can be diagnosed only by breathing tests on patients. In the 130 cancer diagnoses that have been performed, the accuracy of this method is as high as 90%. The British Journal of Cancer believes that this method will completely change the existing cancer diagnosis methods and effectively improve the diagnosis efficiency of cancer.
It is reported that there are about 7,000 new patients with gastric cancer in the UK each year. Most of the patients are in advanced stage at the time of diagnosis. 40% of patients can survive for at least 1 year after diagnosis, but only 20% can survive for 5 years after treatment. the above. At present, the doctor's method in diagnosing gastric cancer is to examine the esophagus and stomach wall of the patient through a probe and a micro-camera, and the new method is to conclude by analyzing the gas exhaled by the patient.
The gas exhaled by patients with gastric cancer will contain volatile organic compounds, which can be detected by the correct medical equipment. Previously, researchers have tried to diagnose lung cancer by this method, and Professor Hossam Heck of the Israel Institute of Science and Technology believes that this method is very suitable for the diagnosis of gastric cancer, among the 130 patients involved in the study, 37 For example, 32 patients with gastric ulcer, and the remaining 61 patients with common stomach pain.
In addition to being able to diagnose gastric cancer patients with 90% accuracy, this method can even determine the stage (early or late) in which the cancer is located. The research team is currently conducting larger studies to test and diagnose more patients.
"The application prospects of this research result are very broad. What they have to do now is to determine the reliability of this method through large-scale experiments." Kate Luo, director of clinical research at the British Cancer Research Center, said, "For gastric cancer. For the patient, only 20% are currently able to undergo surgery at the time of diagnosis, and most of the patients are already in advanced stage. Therefore, this method is expected to confirm the patient in the early stage of cancer, which will greatly improve the patients with gastric cancer. Survival rate."
