BACKGROUND: Endoscopic submucosal dissection (ESD) is a widely accepted procedure for superficial esophageal squamous cell @entity5 (ESCN) because of a high complete resection rate. However, there were a few reports about the long-term outcomes of these @entity1 due to short follow-up periods. AIMS: We aimed to evaluate the 5-year survival after ESD for superficial ESCN. METHODS: This was a retrospective cohort study performed at a single institution. Between 2006 and 2009, 94 @entity1 with superficial ESCN underwent ESD. Eighty-three @entity1 (93.3%) who had completed an extended period of observation of at least 5 years were enrolled. The main outcomes were the 5-year survival rates. The secondary outcomes were the cumulative incidence rate of metachronous ESCN, and the clinical outcomes. RESULTS: The 5-year relative overall survival rate was 99.0%, whereas the cause specific survival rate was 100% during 72.9 months of median follow up period. Subgroup analysis showed that the 5year survival of @entity1 with EP/LPM and MM/SM1 (submucosal invasion <= 200 m) were 100% and 89.0%, respectively. The cumulative incidence rate of metachronous ESCN at 5 years was 16.8%. CONCLUSION: ESD for superficial ESCN is a curative treatment with a favorable 5-year survival rate.
