October 2023—In living up to its promise as a new technology that will revolutionize clinical care through greater ease, speed, and accuracy of diagnosis, digital pathology has been sluggish. While many analysts, starting at least two decades ago, forecasted that digital pathology would elbow aside glass slides for good, that milestone is still far out of reach. As health economist and chief executive officer of the New York City-based digital pathology company Paige, Andy Moye, PhD, puts it bluntly: “In probably 90 to 95 percent of the cases in the U.S., a pathologist still makes the diagnosis of cancer the way they did it back in 1910: by looking at a glass slide under a microscope.” Mark Lloyd, PhD, vice president of pathology for Fujifilm, says he wouldn’t be surprised to hear that perhaps only five percent to 10 percent of hospitals have moved beyond using only glass slides to offer pathologists digital pathology capability. In fact, Dr. Lloyd thinks those percentages are overstated. What is the market share for the clinical use of digital pathology?
