A CASE OF EARLY-STAGE GASTRIC CANCER WITH UNDIFFERENTIATED COMPONENT WITH INGUINAL LYMPH NODE AND MULTIPLE BONE METASTASES 7 YEARS AFTER ENDOSCOPIC SUBMUCOSAL DISSECTION

Abstract

A 46-year-old woman underwent an upper gastrointestinal endoscopy for physical examination in 2013 and received a diagnosis of Helicobacter pylori gastritis; a 0-Ⅱc lesion was found on the lesser curvature of the stomach. Histopathological diagnosis indicated a signet ring cell carcinoma. ESD was performed for the diagnosis of early-stage gastric cancer, and the final pathological stage was pStage Ⅰ [10×9 mm, sig＞tub2, pT1a, ly (-), v (-), HM0, VM0]. We performed regular follow-up CT scans and upper gastrointestinal endoscopy for 5 years after ESD, but no recurrence was observed. However, 7 years after ESD, a mass in the left inguinal region was diagnosed as an inguinal lymph node and multiple bone metastases of gastric cancer, which were treated with chemotherapy; nevertheless, the patient could not be saved.
