Long-term survival after resection of a gastric metastasis from transverse colon cancer: a case report.

Metastatic neoplasms in the stomach from remote primary tumors are uncommon, and gastric metastases of colorectal origin are rare. We herein report a case of gastric metastasis originating from transverse colon cancer in a 61-year-old female patient. Curative right extended hemicolectomy and partial gastrectomy were performed. Histologically, both the colon and stomach tumors were moderately to poorly differentiated adenocarcinoma with similar features. The postoperative TNM classification was stage IV disease (T4N0M1). The patient received 7 cycles of postoperative bevasizumab+FOLFOX (oxaliplatin plus an infusion of 5-fluorouracil/levofolinate) therapy and 4 cycles of additional chemotherapy with bevacizumab+FOLFIRI (irinotecan plus an infusion of 5-fluorauracil/levofolinate).The patient has a good quality of life with no signs of recurrence at seven years and four months after surgery.
