Advancements in AI-driven cancer blood tests

Overview

Advancements in liquid biopsy technology continue to evolve, with research emphasizing the ability to detect cancer years before clinical diagnosis. A longitudinal study involving the Ontario Health Study found that epigenetic alterations and cell-free DNA signatures can appear in blood plasma up to eight years before a diagnosis, with particularly strong molecular warning signs noted in prostate cancer patients.

In clinical applications, the Melody trial at Cork University Hospital is investigating liquid biopsies as a less invasive alternative to traditional tissue biopsies for identifying genetic characteristics in advanced breast cancers. Regarding pancreatic cancer, an international research team developed the PANXEON blood test, which utilizes artificial intelligence to analyze circulating microRNA, exosomal microRNA, and the protein CA 19-9. In clinical testing, this method correctly identified 87% of pancreatic cancers at stages 1 and 2. Additionally, researchers at the Mayo Clinic have used AI to analyze CT scans, finding that changes in subcutaneous and visceral fat may serve as early indicators of pancreatic cancer.

Further developments in Multicancer Early Detection (MCED) are being highlighted by experts from the National and Kapodistrian University of Athens. This approach utilizes blood tests to simultaneously detect multiple cancer types by analyzing cell-free DNA for specific methylation patterns. The PATHFINDER 2 study has demonstrated that the Galleri test can significantly increase the detection of various cancers, including pancreatic, ovarian, and liver cancer, with a 91.3% accuracy in predicting the likely organ of origin. Clinical data from the NHS-Galleri study, a large-scale randomized trial in England, supports the value of this method in identifying cancer signals and guiding subsequent diagnostic procedures.
