Larynx-associated lymphoid tissue (LALT) in young children. Ongoing mutation in MALT lymphoma immunoglobulin gene suggests that antigen stimulation plays a role in the clonal expansion. Most cases of primary salivary mucosa-associated lymphoid tissue lymphoma are associated either with Sjoegren syndrome or hepatitis C virus infection. The authors thank Afua Adjeiwaa Mensah for manuscript review and Rita Gianascio Gianocca for editorial assistance. The coding genome of nodal marginal zone lymphoma reveals recurrent molecular alterations of PTPRD and other Jak/Stat signaling genes [abstract]. Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Rituximab, the anti-CD20 chimeric antibody, is a key component of therapy. This involves a small operation called a biopsy, which is usually done under a local anaesthetic. Indeed, they arise from lymphoid populations that are induced by chronic inflammation in extranodal sites. Endemic in the Middle East, the immunoproliferative small intestinal disease (IPSID), previously also known as α-heavy-chain disease or Mediterranean lymphoma, is a special subtype of MALT lymphoma. [3], Gastric MALT lymphoma is frequently associated (72–98%) with chronic inflammation as a result of the presence of Helicobacter pylori,[4] potentially involving chronic inflammation, or the action of H. pylori virulence factors such as CagA.[5]. Chan W, Armitage J, Gascoyne R, et al. Please enable it to take advantage of the complete set of features! At a median follow-up of 24 months, only 2 patients with responsive disease experienced relapse.72, The prevalence of B burgdorferi infection in patients with cutaneous MZL exhibits important variations among different geographic areas, with higher detection rates in areas where it is endemic. Rationale: 21(2):347-66. [Medline]. Effects of Helicobacter pylori eradication on early stage gastric mucosa-associated lymphoid tissue lymphoma. Immunol Cell Biol. Assessment of disease dissemination in gastric compared with extragastric mucosa-associated lymphoid tissue lymphoma using extensive staging: a single-center experience. You are likely to have a breath test to check for H. pylori in your stomach. Rosand CB, et al. Histologic transformation in marginal zone lymphomas. If you don’t want to take part in a clinical trial, or if there isn’t one that is suitable for you, you are most likely to be treated with radiotherapy or with rituximab combined with chemotherapy. Indeed, there is no clear consensus for the treatment of patients with gastric MALT lymphoma requiring further treatment beyond H pylori eradication or with extensive disease. National Comprehensive Cancer Network guidelines V.2.2013: non-Hodgkin’s lymphoma. [17] The purine nucleoside analogs fludarabine and cladribine also demonstrate activity,[18] the latter conferring a CR rate of 84% (100% in those with gastric primaries) in a small study. Gastric marginal zone lymphoma is associated with polymorphisms in genes involved in inflammatory response and antioxidative capacity. The unifying characteristic is a diffuse infiltrate that invades epithelial structures and disrupts epithelium, causing a lymphoepithelial lesion. Chronic inflammation and extra-nodal marginal-zone lymphomas of MALT-type. MALT lymphomas: pathogenesis can drive treatment. Arthritis Rheumatol. If you had gastric MALT lymphoma, you might have an endoscopy every 3 to 6 months for the first 2 years after your treatment. Lymphoid follicles are ubiquitous to MALT lymphoma but may be indistinct as they are often overrun or colonized by the neoplastic cells. EGD, esophagogastroduodenoscopy; RT, involved-field radiotherapy (24-30 Gy to the stomach and perigastric nodes given in 3-4 weeks). 2014 Mar. In general, the treatment should be ‘‘patient-tailored,’’ taking into account the site, the stage, and the clinical characteristics of the individual patient.
