Research by an international team of investigators has demonstrated the ability of trained dogs to detect aggressive prostate cancer from urine samples, and suggests that an artificial neural network could learn from this olfactory capability. The scientists say findings from the study, which is reported in PLOS One, could feasibly be used to help direct the development of novel, machine-based tools for detecting prostate cancer, which integrate canine olfaction with the analysis of volatile organic compounds (VOCs) in urine, microbial profiling, and artificial neural network (ANN)-assisted examination. Study lead Claire Guest, from Medical Detection Dogs, in the U.K., and colleagues in the U.K. and U.S., claimed, “We’ve shown it is possible to replicate the dog’s performance as sensors and brains, it is now time to put this technology in every smartphone.”
