In the flurry of presentations on early detection of cancer at the 2023 American Society of Clinical Oncology Annual Meeting, Grail LLC stood out for the number of sessions and the strength of its results. In a real-world study presented, Grail’s Galleri multi-cancer early detection (MCED) test cancer signal origin (CSO) demonstrated accuracy of 91%.
The 2023 American Society for Clinical Oncology Annual Meeting featured several notable developments on the diagnostics side, including significant advances in multi-cancer early detection (MCED). Grail Inc. presented its results from SYMPLIFY, the first major study of its MCED test in symptomatic patients. The test showed a negative predictive value of more than 97% and a positive predictive value that exceeded 75% in individuals who presented to primary care with non-specific symptoms that prompted a referral for cancer evaluation.
Exact Sciences Corp.’s long-term analysis of results from the Detecting cancers Earlier Through Elective mutation-based blood Collection and Testing (DETECT-A) study found that all patients diagnosed and treated for stage I or II cancers identified through its blood-based multi-cancer early detection (MCED) test remained cancer-free more than four years after diagnosis. Half of all the participants with cancer detected remained alive at four years, notable because most of the detected cancers had no recommended screening tests or standards. The results will be presented at the American Society of Clinical Oncology meeting June 2-6.
From Carl Icahn’s point of view, Illumina Inc.’s desired reintegration of its former spinoff is more a poisoned chalice than a holy Grail.

Some of the most exciting news out of the European Society for Medical Oncology Congress 2022 in Paris surrounded the rapidly evolving field of multi-cancer early detection (MCED), which offers the dual benefits of identifying malignancies at a more easily treated local stage and enabling screening for the 70% of cancers that lack recommended screening tests.
