Abstract
Background Treatment recommendations for gastric mucosa-associated lymphoid tissue (MALT) lymphoma are based on case series and expert opinions. Only a few previous studies have focused on the long-term outcomes of gastric MALT lymphoma, especially according to stage. Methods Patients diagnosed with gastric MALT lymphoma from January 2000 to December 2018 at nine university hospitals in Korea were included. Clinical data of medical history, endoscopic features, histological diagnosis, results of Helicobacter pylori (H. pylori) testing, stage, treatment conditions, and outcomes were collected. Results A total of 1,163 patients was enrolled, and 97.6% (n=1,038) of patients were diagnosed as stage IE. 10-year overall survival (OS) for the entire population was 99.1% and was better for patients in stage IE compared with patients in stage III/IV (p=0.002). The 10-year OS for H. pylori-positive patients was better than that of H. pylori-negative patients (p=0.022). Multivariate analyses revealed initial stage III/IV as a prognostic factor associated with over-all survival. Conclusion The majority of gastric MALT lymphoma patients are diagnosed at an early localized stage in Korea. The overall survival rate of gastric MALT lymphoma is excellent and is associated with the initial stage of the disease.

Abstract
The diagnosis of gastric MALT lymphoma is frequently difficult for the general histopathologist. During recent years there have been relevant changes in the therapeutic approach to gastric MALT lymphoma and our knowledge about its pathogenesis has greatly improved. The management of this disease actually requires a close cooperation between the histopathologist and the clinicians. The histology report of biopsies of a newly diagnosed or of an already treated case implies information of clinical and therapeutical relevance. This paper aims at giving the histopathologist a general knowledge about the state of art of this disease and its management. The diagnostic process leading to a complete and competent report is then described step by step.

Abstract
BACKGROUND Eradication of Helicobacter pylori with antibiotics is the established initial treatment of patients with localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, there are few reports on follow-up modalities to identify sustained remission in patients who achieve complete remission (CR). We therefore investigated the role of abdominal computed tomography (CT) as follow-up after CR with H. pylori eradication. PATIENTS AND METHODS We retrospectively analyzed 122 patients with H. pylori-positive stage I(E1) gastric MALT lymphoma who achieved CR with successful H. pylori eradication. RESULTS The median follow-up after CR was 35 months (range 3-140 months). At a median of 17 months (range 12-21 months) after CR, 7 of 122 patients (5.7%) experienced lymphoma recurrence, all cases of which were confined to the gastric mucosa and were detectable only by endoscopy with multiple biopsies. At the time of recurrence, four of seven patients showed re-infection by H. pylori. Eradication therapy was successful in these patients, resulting in both bacterial eradication and tumor regression. Three patients who experienced histologic recurrence without H. pylori re-infection were observed by a watch and wait strategy and again achieved CR. CONCLUSIONS None of the patients with H. pylori-positive stage I(E1) gastric MALT lymphoma who experienced tumor recurrence after CR with successful H. pylori eradication showed recurrence at extragastric sites, including lymph nodes without gastric mucosal lesion. These findings indicate that endoscopic biopsies without abdominal CT scans are sufficient to detect recurrence in these patients.

Abstract
BACKGROUND We evaluated the efficacy and toxicity of radiotherapy (RT) in patients with low-grade gastric marginal zone lymphoma. METHODS A retrospective review of consecutive cases of gastric marginal zone lymphoma treated by radical RT at the Peter MacCallum Cancer Centre and Radiation Oncology Victoria between January 1980 and September 2003 was carried out. RESULTS Eighteen patients (11 men and 7 women) were identified. The median age at commencement of RT was 65 years (range 42-84 years). Prior treatment included Helicobacter pylori eradication in 12 patients, chemotherapy in 7 and surgery in 2, whereas 2 patients had no prior therapy. The median time to progression after commencement of last treatment before RT was 4.8 months (range 0-129.4 months). The radiation fields included the stomach plus perigastric and coeliac nodes in 15 patients (83%), stomach plus spleen in 2 patients (11%) and stomach plus para-aortic nodes in 1 patient (6%). The median RT dose was 30 Gy (range 30-36 Gy) in a median 20 fractions (range 17-24 fractions). One patient required treatment interruption for acute toxicity. A complete response on post-RT biopsies was achieved in 17 of 18 patients (94%). With a median follow up of 4.5 years after RT, 3 of these 17 patients (18%) have had a recurrence. At the last follow up, 11 patients were alive in continuous complete histological remission. No late renal toxicity was identified. CONCLUSION Radiotherapy is an effective, well-tolerated treatment for patients with low-grade gastric marginal zone lymphoma, including those who have had prior therapy.

Abstract
OBJECTIVE This article reviews the pathogenesis, diagnosis, and treatment of patients with primary gastric lymphoma, with special attention to the changing role of surgery. SUMMARY BACKGROUND DATA Primary gastric lymphomas are non-Hodgkin lymphomas that originate in the stomach and are divided into low-grade (or indolent) and high-grade (or aggressive) types. Low-grade lesions nearly always arise from mucosa-associated lymphoid tissue (MALT) secondary to chronic Helicobacter pylori (H. pylori) infection and disseminate slowly. High-grade lesions may arise from a low grade-MALT component or arise de novo and can spread to lymph nodes, adjacent organs and tissues, or distant sites. METHODS A review of the relevant English-language articles was performed on the basis of a MEDLINE search from January 1984 to August 2003. RESULTS About 40% of gastric lymphomas are low-grade, and nearly all these low-grade lesions are classified as MALT lymphomas. For low-grade MALT lymphomas confined to the gastric wall and without certain negative prognostic factors, H. pylori eradication is highly successful in causing lymphoma regression. More advanced low-grade lymphomas or those that do not regress with antibiotic therapy can be treated with combinations of H. pylori eradication, radiation therapy, and chemotherapy. Nearly 60% of gastric lymphomas are high-grade lesions with or without a low-grade MALT component. These lymphomas can be treated with chemotherapy and radiation therapy according to the extent of disease. Surgery for gastric lymphoma is now often reserved for patients with localized, residual disease after nonsurgical therapy or for rare patients with complications. CONCLUSION The treatment of gastric lymphoma continues to evolve, and surgical resection is now uncommonly a part of the initial management strategy.

Abstract
The preferred terminology for mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (variously referred to as MALT lymphoma, MALToma, low-grade MALToma, or pseudolymphoma) is marginal zone B-cell lymphoma (MZBL). MZBL, the hallmark of which is the lymphoepithelial lesion, develops as a consequence of Helicobacter pylori infection in susceptible individuals. In general, MZBL is slow growing, can remain localized for years, and has an excellent prognosis. Staging involves endoscopy with biopsy, computed tomography scanning, and endoscopic ultrasound. In patients with limited disease, eradication of H. pylori leads to remission. In patients who fail eradication therapy or have more extensive disease, surgery, chemotherapy, and radiation alone and in various combinations have been used successfully.
