Surveillance strategy based on the incidence and patterns of recurrence after curative endoscopic submucosal dissection for early gastric cancer.

摘要: Background and study aims: To suggest an appropriate surveillance strategy after curative endoscopic submucosal dissection (ESD) for early gastric cancers, based on incidence patterns of local, metachronous, extragastric recurrence. Patients methods: Between 2003 2011, 1497 consecutive patients with 1539 differentiated-type cancers meeting absolute or expanded indication criteria underwent ESD. They were followed up esophagogastroduodenoscopy (EGD) abdominal computed tomography (CT) under a standardized protocol. Long-term outcomes analyzed 1306 at least 1 year’s follow-up. Results: Incidences residual synchronous lesions detected within year 0.13 % 0.87 %, respectively. During median 47 months follow-up, there was local recurrence (0.08 %; cancer) cases metachronous (3.6 %; 44 3 pT2 advanced cancers); all curatively treated. 5-year surveillance, the cumulative curve increased linearly. Median time from ESD to 30 months. There 2 recurrences (0.15 %) in lymph nodes, 5 4 years, respectively, indications. The patient indications palliative operation died cancer progression. Conclusions: constant rate during period years even Therefore, annual biannual EGD CT might be necessary as well
