[Diagnosis and therapy of primary extranodal non-Hodgkin's lymphoma of the stomach].

In the period from 1970-1980 120 patients with NHL were treated. A primary stomach manifestation could be detected in 6.6%. Problems of pre-operative, endoscopic-bioptic diagnostics are discussed and recommendations for a therapeutic proceeding are given. The tumour is surgically removed at stage I and II, which is always followed by polychemotherapy. Primary polychemotherapy is used at stages III and IV. Patients at stage II achieved a complete remission, those at stage IV died within 6 months after diagnosis.
