German scientists invented lung cancer respiration test

Release date: 2017-04-26

German scientists have recently developed a method to detect whether they have lung cancer by analyzing the ribonucleic acid molecules in the respiratory gases of the subjects, with an accuracy rate of 98%.

Ribonucleic acid can bind to stable DNA (deoxyribonucleic acid) fragments in cells to produce different variants, which in turn synthesize different proteins. Scientists from the Max Planck Institute for Cardiopulmonary Research have found that the number of ribonucleic acid variants produced in healthy cells exists in a specific proportion, but the number of variants produced by ribonucleic acid binding to GATA6 and NKX2 genes in cancer cells is proportional to There are differences in healthy cells.

Scientists built models based on ribonucleic acid-related data from health and lung cancer research populations, and tested 138 subjects whose health status was known. The results showed that the diagnostic accuracy of lung cancer was as high as 98%.

Guillermo Barreto, the head of the project team, said the approach would make early diagnosis of lung cancer easier and more reliable and could complement existing diagnostic techniques.

Scientists plan to extend this technology to clinical trials in the future.
