Description
William Ott examines whether EsoGuard, a swallowable cell-collection test, could change the fight against esophageal adenocarcinoma. His 2026 commentary describes a grim starting point. The cancer is among the most lethal, fastest-rising cancers in the Western world, with five-year survival often just above 20%. Most cases surface only once symptoms like difficulty swallowing appear, when cure is harder. The test, marketed by Lucid Diagnostics, aims to catch precancer earlier.
Ott reports a negative test value near 99%, meaning a negative result rules out precancer and could spare millions of unnecessary endoscopies. Critics counter with a positive test value near 30% in some screening groups, so many positive results prove false on follow-up endoscopy, bringing anxiety and extra procedures. Ott weighs the trade-off through Bayesian reasoning: in a highly lethal disease, missing cases matters more than over-calling them, though the debate among medical societies continues.
