According to Japan’s Asahi Shimbun, the research team of the National Cancer Research Center of Japan announced that it has developed a new method for cancer detection. Using this method, only a small amount of blood samples need to be collected, and comprehensive detection of 60 genetic substances related to cancer can be comprehensively detected.
Prior to this, if you want to perform the same comprehensive test, it is usually necessary to extract the tissue of the cancerous part of the patient for testing. The new detection method can repeatedly detect the progress of the patient's cancer without avoiding the burden on the patient, and then can select the corresponding drug according to the test result for treatment.
As the latest research results have proved that although the abnormalities of genetic substances related to different types of cancer such as breast cancer and lung cancer are not the same, some of the abnormalities of genetic substances are common to various cancers. Therefore, an anticancer drug targeting a specific genetic material abnormality may have an effect on other types of cancer if it can produce a specific type of cancer. However, in order to comprehensively detect the abnormality of genetic substances related to cancer, it is necessary to extract the tissue of the cancerous site by puncture or the like.
To this end, the research team at the National Cancer Research Center of Japan looks at the extremely small amount of DNA that is infiltrated into the blood of patients by cancerous tissues, and uses the most advanced analytical device to carry out the DNA infiltrated by cancerous tissues in the blood of 48 patients with pancreatic cancer. Detected. By continuously improving the analytical method for the test data, the research team correctly detected 60 genetic material abnormalities in each patient's 5 ml of blood. In response, the research project leader said that since it has been confirmed that this new test method is suitable for pancreatic cancer, it should be applicable to all types of cancer.
