TLDR
According to a post sharing the study, the GRAIL NHS Galleri randomized trial involved over 142,000 participants and was published in NEJM on September 23, 2026. The post quotes the trial’s conclusion: after three rounds of multicancer early-detection testing plus usual care, researchers did not observe a lower incidence rate of stage III or IV cancers across 12 prespecified cancers than with usual care alone. That measure was the trial’s primary endpoint.
