Trained Dogs More Accurate Than Lab Tests for Diagnosing Prostate Cancer

Service DogIn a report to the American Urologic Association meeting last month, Gianluigi Taverna, MD, of Humanitas Research Hospital in Milan, Italy presented data that specially trained dogs outperformed available lab tests to diagnose prostate cancer. Two German shepherds were trained to recognize the smell of volatile organic substances to distinguish the smell in urine of prostate cancer from healthy individuals and those with other illnesses. The study involved 900 people including 320 prostate cancer patients. All study participants provided a urine specimen which the two dogs smelled. One dog had 100% sensitivity for prostate cancer, 97.8% specificity and 98.9 % accuracy. The 2nd dog had a sensitivity of 98.6%, a specificity of 95.9% and an accuracy of 97.3%. The researchers admit they do not know what chemical or molecule in the urine the dogs smell to achieve such dramatically accurate results. They now begin the difficult task of trying to find it and then create machines that can replicate that accuracy.

While I applaud the study and the curiosity of the researchers I believe we already have the technology available and they are called dogs. From a cost effective standpoint training more of “mans’ best friend seems to be the most cost effective way to accurately detect prostate cancer.
