 Endoscopic therapy is often used for superficial Barrett's carcinoma(BC). However, there is an urgent need to clarify the risk factors possibly involved in recurrence or metastasis. In this report, we address a range of potential risk factors on the basis of clinicopathological reports from Western countries and discuss the results of a questionnaire survey conducted by us.

 For Western populations, the criteria for“low-risk”superficial BC include a tumor size of ≦20mm, an intramucosal location, a well-to-moderately differentiated histology, and absence of lymphovascular invasion. Our data were mostly concordant with these risk factors.

 Many existing reports have indicated that submucosal cancers invasive to the superficial submucosal layer are curable if no risk factors other than depth are evident. Our present data indicated that many submucosal cases had no risk factors and were completely curable. As a benchmark for classification into“SM1”and“SM2”, 500μm is considered to be more suitable than 200μm.
