[Standard intervention in primary lymphoma of the stomach--initial results of a prospective multicenter study]

An R0 resection seems to be a rather aggressive treatment, but can be achieved in 80% of localized gastric lymphomas and should be seen in contrast to other effective treatment modalities. For curative treatment at stage EI1-EII1, total gastrectomy with systematic lymphadenectomy (D2) seems to be necessary. Basic information about the clear diagnosis, tumor dissemination and the individual prognosis only becomes available by a standardized operation as part of multimodal therapeutic concepts.
