title: Role of surgery in patients with primary non-Hodgkin's lymphoma of the stomach: an old problem revisited.
abstract: The literature after 1980 dealing with the treatment of primary gastric non-Hodgkin's lymphoma (stages I and II) is reviewed. Gastrectomy is recommended for patients with acute symptoms at presentation or with complications of chemotherapy or radiotherapy. In elective cases, patients with stage I disease may be candidates for gastrectomy as a single therapy, provided that tumour-free resection margins are achieved. There is no evidence of substantial benefit from adding postoperative chemotherapy or radiotherapy after an apparently radical resection. In stage II disease, the best results are achieved with ablative surgery plus adjuvant therapy. The resection volume should be limited to macroscopically involved structures, in principle avoiding total gastrectomy and extensive lymph node dissection, since residual disease may be optimally controlled with radiotherapy or chemotherapy. Primary chemotherapy, with or without radiotherapy, represents an experimental approach; the advantages of sparing the stomach must be balanced against the toxicity of an aggressive chemotherapy regimen and the risk of emergency operation for iatrogenic complications.
