Report on a workshop convened to discuss the pathological and staging classifications of gastrointestinal tract lymphoma.

It was considered timely to review the pathological and staging classifications of GI tract lymphoma. This meeting specifically did not address the question of treatment; the management of GI tract lymphoma could perhaps form the basis for a further workshop. The following recommendations were made: to adopt the Isaacson histological classification, that all patients with GI tract lymphoma be investigated uniformly, to record the prognostic factors described above, to use the staging classification shown above. It is hoped that these recommendations will be taken into account in the design of future clinical trials of therapy for GI tract lymphoma.
