Orlando, Fla. (April 8, 2019) – Dogs have 10,000 times more pronounced odor receptors than humans, which makes them very sensitive to odors that we can not see. A new study has shown that dogs can use their highly developed scent to select blood samples from people with cancer with nearly 97 percent accuracy. The results could lead to new approaches to cancer detection that are cheap and accurate, but not invasive.
"Although there is currently no cure for cancer, early detection offers the best hope for survival," said Heather Junqueira, chief researcher at BioScentDx, and conducted research. "A very sensitive cancer detection test could potentially save thousands of lives and change the way it treats the disease."
Junqueira will present this research at the annual meeting of the American Society for Biochemistry and Molecular Biology during a meeting of experimental biology in 2019, to be held from 6 to 9 April in Orland, FL.
For a new study, Junqueira and her colleagues used a form of click training to teach four beagles to distinguish normal blood serum and samples from patients with malignant lung cancer. Although one beagle – called Snuggles – was unmotivated to perform, the remaining three dogs correctly identified lung cancer patterns 96.7% of the time and normal samples 97.5% of the time.
"This work is very exciting because it opens the way for further research in two ways, and both can lead to new cancer detection tools," Junqueira said. "One uses dog scent detection as a cancer screening method, and others would identify the biological compounds that dogs discover and then project cancer detection tests based on these compounds."
BioScentDx plans to use the discovery of the scent of dogs to develop a non-invasive way of screening cancer and other life-threatening diseases. As a next step, the company launched a Breast Cancer Study in November, in which participants donated samples of their breath to sample trained dogs who sniffed cancer. Researchers also plan to separate samples on their chemical components and introduce them to dogs to isolate substances that cause the scent that puppies detect.
Heather Junqueira will present the results from 11:45 am to 1:00 pm on Monday, April 8 at the Exhibition Hall-West B, Orange County Convention Center (poster E254 635.10) (abstract). Contact the media team for more information or get a free copy of the meeting.
