Copy number alterations detected by whole-exome and whole-genome sequencing of esophageal adenocarcinoma

Abstract excerpt

BACKGROUND: Esophageal adenocarcinoma (EA) is among the leading causes of cancer mortality, especially in developed countries. A high level of somatic copy number alterations (CNAs) accumulates over the decades in the progression from Barrett's esophagus, the precursor lesion, to EA. Accurate identification of somatic CNAs is essential to understand cancer development. Many studies have been conducted for the...
