Beijing: Researchers have developed a new learning artificial intelligence (AI) system which can diagnose and identify cancerous prostate samples as accurately as any pathologist. According to the researchers, this holds out the possibility of streamlining and eliminating variation in the process of cancer diagnosis. It may also help overcome any local shortage of trained pathologists.
“This is not going to replace a human pathologist. We still need an experienced pathologist to take responsibility for the final diagnosis,” said lead author Hongqian Guo from the Nanjing University in China. “What it will do is help pathologists make better, faster diagnosis, as well as eliminating the day-to-day variation in judgement which can creep into human evaluations,” Guo added.
They were also able to identify different Gleason Grades in the pathology sections using AI; ten whole mount prostate pathology sections have been tested so far, with similar Gleason Grade in the AI and human pathologist’s diagnosis.
The group has not started testing the system with human patients.
“The system was programmed to learn and gradually improve how it interpreted the samples. Our result show that the diagnosis the AI reported was at a level comparable to that of a pathologist. “Furthermore, it could accurately classify the malignant levels of prostate cancer,” Guo added.
