Abstract: OBJECTIVES: The metaplastic intestinal epithelium in Barrett esophagus (BE) occasionally contains Paneth cells; however, little is known regarding the prevalence and significance of Paneth cell metaplasia (PCM) in BE. METHODS: We evaluated 757 esophageal biopsy specimens with intestinal metaplasia (IM) for PCM. Outcome analysis was performed in 299 cases with complete clinical data using multinomial logistic regression. RESULTS: Thirty-one percent (234/757) of the IM cases showed PCM. Paneth cells are decreased when BE epithelium becomes increasingly dysplastic. Long-segment BE shows significantly more PCM than short-segment BE. On follow-up biopsies, patients without PCM (NPCM) are three times more likely to regress than patients with PCM, regardless of dysplasia, BE segment length, age, or sex. However, there is no significant difference in terms of progression to dysplasia/adenocarcinoma between the PCM and NPCM groups. CONCLUSIONS: The presence of PCM is associated with less disease regression and is not associated with more disease progression.
