One Pathway for Esophageal Cancer?

Molecular profiling reveals precursor signals in BE-negative esophageal cancer

1

Esophageal adenocarcinoma (EAC) may arise through a shared biological pathway linked to Barrett’s esophagus (BE), even without BE being identified.
2

The study analyzed 3,100 EAC patients from 25 UK centers, revealing similar demographic and risk profiles in those with and without detectable BE.
3

Genomic analyses showed significant overlap in key driver mutations and mutational burden between BE-positive and BE-negative tumors.
4

Markers of intestinal metaplasia were found in tumors lacking histologically identifiable BE, indicating persistence of precursor biology.
5

The absence of detectable BE does not rule out underlying precursor changes, suggesting molecular approaches may enhance early detection.
