Gastric cancer with repeated metastasis in the colonic lumen: a case report and multi-surgical experience

Abstract

Poorly differentiated gastric adenocarcinoma is commonly associated with lymph node metastasis, peritoneal spread, and liver metastasis but rarely with intraintestinal metastasis. Most patients with metastatic gastric carcinoma are unable to undergo surgical treatment and have a poor prognosis. A 42-year-old man with hunger-related abdominal pain was diagnosed as having gastric cancer. After the first surgery (distal partial gastrectomy) and the second surgery (gastric stump carcinoma (GSC) resection), the patient suffered repeated multiple intracolonic metastases and underwent three additional resection operations. The patient survived for 154 months after the first operation. In patients with gastric carcinoma that metastasizes to the colonic lumen, radical resection, if possible, can extend survival. Once patients develop extensive extraintestinal metastasis, radical resection cannot be performed, and patients often exhibit a poor prognosis.
