Paige Announces World’s First Clinical-Grade AI in Pathology
Article Published in Nature Medicine Provides Further Scientific Evidence for Deployment of Computational Decision Support Systems to Improve Patient Care
Paige, the leader in computational pathology focused on building artificial intelligence (AI) to transform the clinical diagnosis and treatment of cancer, announced the publication of an article in Nature Medicine, a leading monthly journal publishing original peer-reviewed research in all areas of medicine, describing an AI system for computational pathology that achieves clinical-grade accuracy levels. The paper provides further scientific evidence that pathologists’ work in diagnosing and treating cancer can be complemented and aided through the deployment of computational decision-support systems to improve patient care.
The team of scientists responsible for the work described in the article developed specially-designed deep learning algorithms to build a system that can detect prostate cancer, skin cancer and breast cancer with near-perfect accuracy. These algorithms are based on a vast dataset of nearly 45,000 de-identified, digitized slide images from more than 15,000 cancer patients from 44 countries.
“After years of in-depth, comprehensive modeling, training, and testing, we are thrilled that Nature Medicine has published our paper, which demonstrates our ability to train accurate classification models at unprecedented scale, and validates our mission to create the world’s first clinical-grade, artificial intelligence in pathology,” said Dr. Thomas Fuchs, Co-Founder and Chief Scientific Officer of Paige, who led the work at his lab at Memorial Sloan Kettering Cancer Center (MSK).
The paper outlines how a series of novel algorithms created using datasets ten times larger than those that have been manually curated performed better and also are more generalizable. The significance of this new development hinges on the fact that curating datasets can be prohibitively expensive and time intensive. By eliminating the need to curate datasets, Paige can now develop many more highly accurate algorithms that can be built into clinical decision support products to help pathologists around the world drive better patient care.
“The publication in Nature Medicine of the algorithm developed by Dr. Fuchs’ lab is an important milestone for Paige. It demonstrates that AI has the potential to support pathologists in delivering quantitative and more accurate diagnoses, improving treatment for patients worldwide. Leveraging even larger training sets, over the past year, Paige has created novel vendor-agnostic systems that demonstrate even better accuracy,” said Dr. Christopher Kanan, lead AI scientist at Paige.
Paige plans to commercialize several of these solutions to address the most pressing needs in pathology to improve patient care. Paige has already built on the academic work described in Nature Medicine to develop a clinical product, based on technology currently under review by the U.S. Food and Drug Administration as a designated Breakthrough Device, for an intended indication different than the one described in the article.
