SCIENCE. Similarly, American scientists have detected DNA of cancer cells in the blood of certain patients a few years before they. In addition, receive a diagnosis of cancer. Their results were published in the journal Cancer Discovery.
The researchers used blood samples collected as part of a study started in 1980. They were particularly interested in patients who had received a cancer diagnosis within 6 months of blood test. Thanks to a genome sequencing technique, they thus identified eight participants who were already showing signs of cancer.
In addition, for six of them, blood samples collected three years before were available. In two thirds of these samples, the DNA of cancer cells was already present. These results suggest that blood tests could detect cancer long before other symptoms appear. Researchers are now working to repeat detect cancer years before appearance this experience, but on a larger group of patients.
To carry out this experience. the team used tests allowing the early detection of several cancers (in English “Multi-Cancer Early Detection” or MCED). As the American Cancer Society explains. these tests are not sufficient to diagnose cancer, but help to detect the presence of anomalies that could be associated with it. Other evaluations are then necessary to establish with certainty the diagnosis.
Nevertheless, the early cancer detection could revolutionize treatment. Detecting cancer earlier would consider more treatment options, explained study authors in a press release. In addition, the state of the tumor being less advanced, it could be easier to treat it.
The American Cancer Society. however, stresses that these tests have not yet been approved by the American Food and Medicated Products (FDA in English) and that more research will be needed before recommending their use by people who have detect cancer years before appearance no cancer symptoms.
Still several steps must actually be taken before these tests are available for the general public. confirm the oncology experts cited in an article in the Smithsonian Magazine. For example. it will be necessary to determine which people would benefit the most from these early detection tests and, above all, how to act following a positive result.
