Comparison of Clinical Outcomes of Gastrojejunal Bypass and Gastrectomy in Patients With Metastatic Gastric Cancer

Background/Aim: Surgical therapy for stage IV gastric cancer patients is still debatable. The clinical outcomes were compared between gastrojejunal bypass and gastrectomy for metastatic gastric cancer patients. Patients and Methods: A total of 110 patients with metastatic gastric cancer who underwent surgery were retrospectively analyzed. Twenty-nine patients underwent gastrojejunal bypass (group B) and 81 underwent gastrectomy (group G). Results: There was no significant difference in the 3-year overall survival between Group G patients with partial gastrectomy and total gastrectomy. However, patients in group G had a significantly better prognosis compared to patients in group B (p=0.01 and 0.03, respectively). The prognosis of patients with postoperative chemotherapy was significantly better in group G compared to group B (p=0.03), whereas it was not significantly different for the patients without postoperative chemotherapy (p=0.24). Conclusion: Gastrectomy in patients with metastatic gastric cancer may improve survival when combined with postoperative chemotherapy.
