Role of surgery in the treatment of primary gastric lymphoma and assessment of new therapeutic approaches

: Controversy remains regarding the best treatment for primary gastric lymphoma (PGL). Recent developments in diagnosis and chemotherapy have changed strategies for this disease. Fourteen patients with primary gastric non-Hodgkin's lymphoma underwent surgery. Before surgery 9/14 patients underwent Helicobacter pylori eradication, and 4/14 were treated with chemotherapy. In two patients chemotherapy was not possible because of risk of perforation recurred. Total gastrectomy with N2 lymphadenectomy, splenectomy, biopsy of mesenteric lymph nodes, and hepatic biopsy were done. Then patients underwent post-operative chemotherapy. Involved-field radiation therapy was made in four patients. The overall survival was 64.2 percent. Surgery was the treatment of choice in cases of gastric lymphoma non-responsive to medical therapy and to control complications or when gastroscopy did not supply correct diagnosis.
