Recent progress in polychemotherapy employed in the treatment of gastrointestinal lymphomas has markedly improved prognosis. Between 1980 and 1986, 22 patients with malignant lymphomas of the gastrointestinal tract were treated at the Department of Surgery at the Hanusch Medical Center, in cooperation with the Department of Hematology and Oncology. 19 patients underwent surgery. The average observation time was 29 months. The rate of survival after 36 months was 64% in the entire patient population. Palliative-surgical interventions combined with chemotherapy equally produced satisfactory results.
