Purpose
The first objective of this study is to confirm the results of complete remission of low-grade gastric MALT lymphoma stage IE & II1E after H. pylori eradication on a larger number of patients (HELYX Part I). If there is no response to the antibiotic therapy, the role of radiotherapy on the course of gastric MALT lymphoma will be investigated as a consecutive therapeutic option for patients that are H. pylori- negative, t(11;18)-positive or failure candidates after eradication therapy. Furthermore, the method of radiation, and the radiation dose will be investigated and standardized. HELYX PART II is therefore a randomized equivalent study comparing the standard dose of 36Gy vs. a reduced dose of 25.2Gy locoregional. Additional molecular genetic analysis will be performed to try to understand pathogenetic mechanisms of lymphomagenesis.

Experimental data have extended the knowledge of the mere association of gastric MALT lymphoma and infection with Helicobacter pylori. If we summarise the reports to date on the results of treatment of gastric low-grade MALT lymphoma in an early clinical stage (EI) by H. pylori eradication we find a complete remission figure of 77% in more than 200 patients.
As a therapy with less side effects than radiation, surgery or chemotherapy and as a stomach-conserving treatment, eradication of H. pylori in patients with low-grade gastric MALT lymphoma in stages IE & II1E should be the treatment of the choice within clinical trials since there are no long-term results available thus far. Besides, pretreatment patient selection and careful follow-up with endoscopy, biopsies and clinical staging including endoscopic ultrasonography is necessary. However, a five to ten year-follow-up will be necessary before the definitive value of Helicobacter pylori eradication can be established. Furthermore, since not all patients respond to this therapy research into the pathogenetic mechanisms of lymphomagenesis is inevitable.
Approximately 20% of patients with antigen-positive, primary gastric low-grade MALT lymphoma in stage I will not respond to eradication therapy. Hence, a consecutive salvage therapy other than surgery is much needed. The aim of the second part of this study is to establish radiation therapy as a salvage therapy. Furthermore, the effect of a reduced radiation dose (25.2Gy) compared to the standard dose (36Gy) will be investigated with the aim of non-inferiority of both doses.
