[Non-Hodgkin's lymphomas of the stomach. Therapy from the surgical viewpoint]

About 2-5% of all gastric tumours are Non-Hodgkin Lymphomas (NHL). In the last years we treated 15 patients with NHL of the stomach. Six of these patients were classified to group IE according to Ann Arbor classification, four to group II (three II 1 E and one II 2 E). In group III E were two patients (one III S and one III E) and one patient was classified to group IV. Ten patients displayed low grade and five high grade malignancies with respect to the Kiel classification. We performed in group I three gastrectomies and three BI resections. In four patients of group II two gastrectomies and two BI resections were carried out and in group III two BI resection. Our treatment policy consisted of operation and radiation in IE, to operation and chemotherapy in high grade lymphomas of group II, and operation plus radiation in low grade malignancies of group II. In group III we treated radiation, chemotherapy and operation and in group IV radiation and chemotherapy. In group I five patients survived, in group II two out of four and in group III one of two. The patient of group IV died within two years after diagnosis.
