Australian researchers have developed an experimental test that, if successful in future studies, could be the first to easily detect any type of cancer currently described by Medicine.
The study conducted by scientists from the University of Queensland and published on Tuesday 4 in the scientific journal Nature Communications used cell samples from 200 patients with the most common tumor types. different and revealed that some expressions of DNA differed between cancer cells and healthy cells
Australian researchers have observed, through experiments in which cells were dissolved in an aqueous solution and also affinity for gold, that cells of all types of cancer had the same behavior in these experiments.
Scientists have discovered that a simple blood sample can test cells and discover in just ten minutes if such a change in DNA indicates the presence of cancer cells in the body
researchers, the accuracy of the test was 89%, that is, if it detected the presence of cells.
Scientists note, however, that if the test is able to diagnose any cancer cell, it does not indicate the type of tumor or the severity of the identified disease
Progression
According to the physician Tulio Pfiffer, a clinical oncologist at Sírio-Libanês hospital, the test represents a major advance in the early detection of tumors. "Today, we even have tests that identify proteins clbadified as tumor markers, but these markers are inaccurate and exist only in certain types of tumors."
The search for Australian scientists, says Pfiffer, creates a new approach to the detection process. cancer cells. "Today, with biopsies, we are looking for changes in the biology of DNA.With this test, which is much simpler, we will examine the physicochemical aspects of DNA altered by the tumor." , such as the fact that he adds water molecules or gold ingots or not, explains the journal expert The State of S.
