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.
