Cancer treatment new dawn detection cancer may only need blood test
Release date: 2018-02-12
Cancer is a major killer of modern humans, and sometimes advanced medical technology can't do anything about it. However, a study in the United States may bring a new dawn to cancer treatment. According to French media FranceBleu, the American study called "CancerSEEK" is trying to test the most common 8 cancers by blood test.
"CancerSEEK" is hosted by a research team at Johns Hopkins University in Baltimore, Maryland, and is still in the experimental phase. The researchers used blood tests to detect eight common cancers. The study was carried out in thousands of patients whose tumors have not spread. The researchers also started another related study, which is expected to take five years and will involve 50,000 women between the ages of 65 and 75. They have never had a cancer experience before, and the researchers hope to use more systematic methods to detect tumors when the cancer has not yet developed symptoms.
The principle of "CancerSEEK" is to detect abnormalities of 16 oncogenic genes and 8 specific proteins considered as "biomarkers" by detecting blood. Through this combination of tests, the detection can more effectively determine the diseased organ. During the study period, the diagnosis rate for different cancers ranged from 33% to 98%, but the average diagnosis rate was 69%, especially for early-stage cancers such as ovarian cancer, liver cancer, stomach cancer, pancreatic cancer, and esophageal cancer. The rate of diagnosis by blood tests is higher.
The cost of a "CancerSEEK" blood test is expected to be less than $500 (about 3199.5 yuan), which also brings a glimmer of hope for cancer patients. However, there are some problems in this way. For example, the protein used for detection will also mark tissues damaged by other causes, such as inflammatory diseases; in addition, the results of arthritis patients without cancer will be misdiagnosed as positive; If the tumor is small, the earlier the detection is more difficult, the current detection rate of very early cancer without symptoms is only 43%.
