Management of non-Hodgkin lymphoma in adults in Scandinavia, United Kingdom, and The Netherlands. Report from the European School of Oncology intercity meeting at Huddinge Hospital, 3rd June, 1988.

Current treatment strategies in northern Europe of non-Hodgkin lymphoma are presented. High-grade malignant lymphomas have been treated with doxorubicin-containing polychemotherapy in various modes. The advantage of six-drug regimens over CHOP-like therapy is as yet not proven. Patients with the ability to tolerate the calculated dose have good prognosis. High-dose therapy and bone marrow transplantation should be considered in poor-risk patients with lymphoblastic lymphomas in first remission, patients with all high-grade histologies in partial remission after first-line therapy and patients with relapse that are still responsive to therapy. Preliminary results from autologous bone marrow transplantation in follicular lymphoma are also encouraging. Chlorambucil induces multiple remissions in follicular lymphoma, with a median duration of the 1st, 2nd and 3rd remission being the same. The watch and wait strategy seems justified initially in most asymptomatic generalized low-grade malignant lymphomas. Systemic therapy is required in aggressive stage II-IV lymphomas. A meticulous investigation is needed for stage I patients before giving local treatment only. Immune phenotyping is of great value for diagnosis and staging. Liver, but not bone marrow involvement seems to be an adverse prognostic factor. Follicular lymphoma is an example of a dynamic tumour with gradual cellular changes associated with new and more malignant clinical signs.
