AI is now being used to detect prostate cancer

July 28, 2020

It can do it with near-perfect accuracy.

As reported by SciTech Daily, the UPMC and University of Pittsburgh researchers have demonstrated how AI has become the main tool in detecting prostate cancer in humans. 

It was said that while humans are good at identifying anomalies in the body, there is still a chance where each has its own bias based on past experiences. But instructing a machine and utilizing AI to recognize anomalies mean that it will base details on what it knows which in turn can effectively detect cancer even at its early stages.

Rajiv Dhir, M.D., M.B.A., chief pathologist and vice-chair of pathology at UPMC Shadyside and professor of biomedical informatics at Pitt trained the AI to recognize prostate cancer by letting it go through various images of healthy and abnormal tissue. From there, it was given more than 1,600 slides from 100 patients to determine if the cancer is present.

It resulted in the AI giving 98 percent sensitivity and 97 present specificities in detecting cancer. The value is higher than previously reported algorithms who went through the same slides. The AI also managed to effectively identify more details like tumor grading along with the invasion of the surrounding nerves. 

Despite the accuracy, a human is still the best way to evaluate the case. The AI may have identified potential cancer on a patient, but enough evidence of malignancy elsewhere in the body could mean that is safe.

Still, breakthroughs in AI such as cancer detection is a step towards harnessing the power of technology to improve different methods of healthcare.
