From more powerful diagnostic imaging to genetic testing to immunotherapy innovations, new and emerging technologies will play a key role in accelerating the fight against cancer and potentially help reduce the mortality rate even further. of years ago, providers started taking digital images of diseased tissue, and researchers built repositories of imaged tumors from different patients. A new world came into view, aided by algorithms that let computers make predictions about which cells appear cancerous and which don’t. “There’s a sense of tremendous advances in treating cancers that would otherwise have killed the patient very quickly,” says Joel Saltz, a pathologist and Stony Brook Medicine’s vice president for clinical informatics. “People are having months or years of symptom-free life.” “Computing power has grown by a factor of a million in the last 25 years, which really impacts how long it takes to do computations,” Saltz says. “The AI performs complex statistical analysis that can circle cancer in imaging after you teach it the general rules of what tumor cells look like.” SMARTER DETECTION THROUGH AI Not long ago, detecting cancer required a biopsy, which a pathologist would examine through a microscope to determine if cells had turned malignant. Then, a couple Illustrations by Yukai Du Now, AI systems wielding a powerful form of machine learning called deep learning are improving the predictive assistance they can offer, allowing researchers like Saltz to connect image analysis to patient-specific biochemical profiles. 59
