Artificial intelligence tool grades severity of rare cancers with high precision

2 min read

Scientists have developed an artificial intelligence tool that can grade the severity of a rare cancer with high precision, a new study suggests.

While current methods for grading retroperitoneal sarcoma, a cancer that occurs in the connective tissue at the back of the abdomen, require a small sample of the tumor to be collected and analyzed under a microscope, the AI tool was nearly twice as effective at grading the aggressiveness of the retroperitoneal sarcoma as the existing methods.

The AI tool was able to grade tumors from 89 patients with 82% accuracy, compared to the current method’s 44% accuracy.

Researchers at the Royal Marsden Hospital and Institute of Cancer Research in London said the AI tool could lead to better outcomes for patients through faster diagnosis and more effective personalized treatment.

“We are very excited about the potential of this state-of-the-art technology,” said Professor Christina Messiou, Consultant Radiologist at the Royal Marsden NHS Foundation Trust and Professor of Personalized Tumor Imaging at The Institute of Cancer Research, London.

“It could lead to better outcomes for patients through faster diagnosis and more effective personalized treatment.”

The AI tool uses a technique called radiomics to identify signs of cancer that are not visible to the naked eye in scans. The tool was trained on a dataset of scans from 170 patients with retroperitoneal sarcoma.

The researchers hope that this AI tool will eventually be used globally to help patients with sarcomas and other types of cancer.

“This technology has the potential to change the lives of sarcoma patients by creating personalized treatment plans based on the specific biology of the cancer,” said Dr. Paul Wong of The Institute of Cancer Research in London.

“It is great to see such a promising discovery.”
