This is the result of four years of research : the development of a new lung cancer screening process, the leading cause of cancer death in the world. This is a simple blood test.

“It’s faster, more practical and less restrictive”

Today, cancer screening and monitoring is most often carried out by imaging or scanner. But researchers from Besançon University Hospital noticed similarities in the blood of patients affected by lung cancer. Six markers detectable in the blood have been identified and now allow them to detect, or not, the presence of a tumor in the patient.

“It’s faster, more practical, less restrictive for both the patient and the community. When we do a scan, we put you in a machine and inject you with a product. A blood test is taken in two or three minutes and can be carried out anywhere With a scanner, there are many more technical constraints. explain le docteur Zohair Selmanico-inventor of the blood test.

To detect a relapse and simplify screening

This innovation is a real breakthrough in the case of lung cancer, which screening is often much later than in the case of colon cancer or breast cancerFor example.

“As part of patient monitoring, it will really be simpler. We will be able to take repeated blood tests and quickly detect if there is a relapse. And as part of screening, we can imagine setting up a monitoring of this type in heavy smokers for example”, explained Zohair Selmani.

Soon to be put into practice in Besançon and elsewhere

For the moment, blood tests are not yet used in Besançon, validation studies are still underway but “this should go very quickly” according to Doctor Selmani. The Besançon University Hospital already uses this type of process to detect other cancers such as colon cancer.For example.

“I am in contact with industries to manufacture user kits and why not make them available to other hospitals within two or three years, being optimistic.”
