[Diagnostic and therapeutic problems of primary non-Hodgkin lymphoma of the stomach]. / Diagnostische und therapeutische Probleme des primären Non-Hodgkin-Lymphoms des Magens.

The primary extranodal manifestation of the non-Hodgkin-lymphomas above all concerns the stomach. An essential problem is the low, exactly positive rate of biopsy. As a rule the non-Hodgkin-lymphoma is diagnosed on the surgical specimen. During 5 years we treated 11 patients with non-Hodgkin-lymphoma, this corresponds to 3.85% of our malignant tumours of the stomach. The anamnesis is uncharacteristic, the endoscopic picture is multiform, penetration and haemorrhage are relatively frequent to be observed. Only in 1 patient of 11 by means of multifarious biopsies the diagnosis could be ascertained preoperatively. At stage I the surgical therapy is sufficient, for all other stages the combination of operation and poly-chemotherapy is the therapy of choice.
