A CASE OF RECURRENCE IN MULTIPLE LYMPH NODES FOUR YEARS AND TWO MONTHS AFTER ENDOSCOPIC SUBMUCOSAL DISSECTION FOR 10mm SIZE, UNDIFFERENTIATED EARLY GASTRIC CANCER

Abstract

A 66-year-old woman had a 10mm size, undifferentiated-type, early gastric cancer in the angle of the stomach. Endoscopic submucosal dissection was performed, and the cancer was completely resected pathologically by the therapy. However, it recurred in multiple lymph nodes four years and two months later. Recently, there have been several reports of recurrence among patients who had undergone endoscopic therapy for undifferentiated-type early gastric cancer on long-term observation. It is unclear whether endoscopic submucosal dissection is the best therapy for undifferentiated-type early gastric cancer. This is currently being studied in a multicenter prospective trial in Japan and the results of the trial are awaited.
