Diagnosis and Staging Research

Researchers have been developing artificial intelligence (AI) tools that could make cancer imaging faster, more accurate, and more informative. But there are also questions about whether these tools are ready for doctors’ offices, whether they will actually help people, and whether that benefit will reach all—or only some—patients.

FDA has expanded the approved uses of the FoundationOne Liquid CDx blood test, known as a liquid biopsy, that can help doctors pick specific treatments for some people with cancer. When used in this way, the test is known as a companion diagnostic.

A method that combines artificial intelligence with an advanced imaging technology can accurately diagnose brain tumors in fewer than 3 minutes during surgery, a new study shows. The approach can also accurately distinguish tumor from healthy tissue.

Cancer researchers have trained a computer program to scan images of tissue samples to differentiate normal lung tissue from the two most common forms of lung cancer. The program also learned to detect cancer-related genetic mutations in the samples.

Research studies show tests that analyze tumor DNA in blood, called liquid biopsies, may help detect cancer early, guide precision cancer treatment, and track treatment response.
