Abstract
Telomere shortening is deeply involved in many types of cancer. Telomere length of esophageal adenocarcinoma (EAC) and Barrett’s esophagus (BE) was examined in Japanese patients. Among BE from cancer free patients (Cancer free), BE from patients with EAC (Adjacent) and EAC tissue (Cancer), Cancer free group presented the longest telomeres, while Cancer group presented the shortest telomeres and Adjacent group presented intermediate telomeres. Direction of endoscopic biopsy, 2 o‘clock direction was also significantly associated with shorter telomere length in non-neoplastic BE (p = 0.027). Shortened telomere highlighted the impact of this molecular change in early carcinogenesis in EAC.
