Researchers at the University of Queensland (Australia) have developed a test that can diagnose, by badyzing blood or tissue biopsy, several types of cancer in just 10 minutes. Scientists have discovered a unique genetic nanostructure found in cancer cells and published the novelty in Nature Communications on Tuesday (4).
"This unique DNA signature at the nanoscale has appeared in all types of bad cancer examined and in other forms of cancer, including prostate, colorectal cancer and lymphoma, "said Commissioner Abu Sina, a member of the study, in a statement. "The levels and patterns of tiny molecules called methyl groups that decorate the DNA are dramatically altered by cancer – these groups are essential for allowing cells to control which genes are turned on and off," he explained. .
The developed technique has shown diagnostic accuracy can reach 90% in tests and can represent an incredible improvement for future patients. Early diagnosis is often linked to the chances of a good prognosis and the development of a quick and non-invasive way to detect the disease in the early stages can confer a quality of life to those who suffer from it.
"We certainly do not know yet about the Holy Grail for all cancer diagnoses, but that sounds really interesting as a marker the universal cancer incredibly simple, and as an affordable and inexpensive technology that does not require complex laboratory equipment like DNA sequencing, "said another research team member, Professor Matt Trau.
