[Role of surgery, its results and complications, in the combined treatment of primary gastric non-Hodgkin lymphoma].

During ten years 580 patients have been treated for gastric tumour in our department, 510 of them were operated on. Resection could be performed in 296 cases. 17 resections, 5.7 per cent of all were performed because of primary non-Hodgkin gastric lymphoma. No gastric lymphoma was found among the non-resected patients. The preoperative histological diagnosis was correct only in 8 cases. MALT origin could be proved in 5 patients. Synchronous adenocarcinoma and lymphoma was diagnosed in 2 patients. Staging was decided according to Lugano classification. There were six stage I, four stage II, and seven stage IV patients. 8 subtotal and 9 total gastrectomy was performed, 5 were extended and 2 were combined. R0 resection could be carried out in five stage I, two stage II and in one stage IV patient. We lost 2 patients in the postoperative period. Patients were treated with adjuvant chemotherapy (VEP, CHOP) except for 2 patients with low grade MALT lymphoma. The likelihood of one-year survival is 73 per cent, average two-year survival is 63 per cent. When the tumour is operable by total gastrectomy we suggest to perform splenectomy as well, despite of the fact that some postoperative complications can be related to it. We think it is reasonable to perform palliative resection in cases of locally extended stage IV tumours, which affect the patient's quality of life: to cease the pain, passage troubles, bleeding and to improve the conditions for adjuvant treatment.
