Early gastric cancer with three gastric gastrointestinal stromal tumors combined with synchronous colon cancer: A case report
Abstract Background: This study presented a rare case of early gastric cancer (EGC) with multiple gastric gastrointestinal stromal tumors (GISTs) combined with synchronous colon cancer and to discuss the progress of treatment in this disease.Case presentation: We report our experience with a case of multiple tumors, which were found at the same time in the abdomen. The patient was a 77-year-old man who was referred for a gastric GIST. Esophagogastroduodenoscopy showed the known lesion (a gastric GIST) on the lesser curvature of the high body and a new lesion on the lesser curvature of the low body with suspicion of EGC. A computed tomographic scan confirmed the presence of a GIST in the stomach and revealed two new lesions. One was suspected to be a 4 cm submucosal tumor on the anterior wall of the high body of the stomach. The other was a wall thickening of the descending colon, which demonstrated the possibility of malignancy. Colonoscopy confirmed synchronous colon cancer. Laparoscopic near-total gastrectomy with D1+ lymph node dissection and left hemicolectomy were performed sequentially without significant events. The patient was discharged without any postoperative complications.Conclusions: We report the case of a rare patient with EGC with multiple gastric GISTs combined with synchronous colon cancer.
