Due to the method of multimodal optical spectroscopy, developed by Canadian researchers, patients with common forms of cancer will be a great life, and reduce the risk of recurrence.

In 2015, scientists from Montreal have developed a manual spectroscope, which allows accurate detection of cancer cells during surgery.

The research team has perfected the invention and developed a new device with improved accuracy, capable of detecting cells of brain cancer, And colon cancer cells, lung and skin. When testing the probe multimodal optical spectroscopy showed the cancer cells with almost 100 percent accuracy.

Details of the study will publish on June 28 at the American Association for Cancer Research journal.

"Minimizing or eliminating the cancer cells during surgery is an important part of cancer treatment, but cancer cells during surgery is a difficult task," - explains Dr. Petrekka, brain cancer researcher. Dr. Frederic Leblond says: "We were able to demonstrate the effectiveness of the technology in the treatment of other forms of cancer This means that more patients will receive higher quality diagnosis, effective treatment and a lower risk of recurrence.."

The advantage of this system is that surgeons can use it during cancer cell detection procedures in real time.

"Technology with high accuracy is required because the surgeons use this information to determine whether cancer cells contain a tissue or not," - concludes Dr. Petrekka.

The probe uses the same technique of Raman spectroscopy as in the first generation of studies to interpret the chemical composition of the tissue. Designed in 2015 and tested on more than 80 patients during surgery probe is now improved. The new version is multimodal and uses a built-in fluorescence spectroscopy for the interpretation of the metabolic composition of cells and diffuse reflectance spectroscopy for the analysis of internal tissue absorption in patients.

During tests in 15 patients with brain surgery, these methods are highly sensitive spectroscopy have been integrated into a single sensor in combination with a detection system, a highly sensitive camera and a spectrometer.

Now the probe - the object of study involving patients with gliomas. The study for the first time demonstrate the clinical benefits of using probes in brain surgery.
