PURPOSE: The aim of this questionnaire survey was to assess the change in treatment modality over time and the current status of clinical outcomes of local treatment in Japanese @entity1 with pathological T1 (pT1) @entity5 . METHODS: A questionnaire survey was conducted by the 81st Congress of the Japan Society for @entity694 . Clinical and pathological outcomes of all eligible @entity1 undergoing local treatment were retrospectively collected from the medical records of each participating hospital. RESULTS: A total of 1371 pT1 @entity1 from January 2006 to December 2008 (Period A), and 659 @entity1 in 2013 (Period B) were registered. Approximately 70  % of @entity1 underwent radical surgery in both periods. The rate of @entity1 undergoing laparoscopic surgery increased from 46.5  % in Period A to 84.7  % in Period B. The indications for local excision were comparable with those for endoscopic intervention in 78  % of institutions. The rate of endoscopic submucosal dissection (ESD) increased from 20.1  % in Period A to 37.9  % in Period B, whereas local excision decreased from 36.9 to 24.1  %. Few @entity1 received adjuvant therapy, and approximately 40  % of @entity1 underwent additional surgery in both periods. Local recurrence was observed in 9.2  % of @entity1 in Period A, with the median follow-up period being 59  months. Eighty-two percent of @entity1 with local recurrence underwent salvage surgery. CONCLUSIONS: Local treatment with various modalities was properly performed for early @entity5 . The number of less invasive modalities, such as laparoscopic surgery and ESD, increased between study periods.
