This study aimed to assess the long-term outcomes of radiotherapy in patients with localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Twenty-seven patients with Stage I gastric MALT lymphoma were treated with radiotherapy from 1999 to 2010. The median age was 65 years (range: 31-84). Fifteen patients were Helicobacter pylori-negative. Thirteen patients were treated with defini...
Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT Lymphoma) of the gastrointestinal tract commonly involves the stomach in the setting of concurrent Helicobacter pylori (H. pylori) infection. Primary ileal MALT lymphoma is rare, and has not been associated with a specific infectious disease. We report a case of a 58-year-old man who presented to the emergency departme...
The eye is protected by the ocular immunosurveillance system. We show that tear duct-associated lymphoid tissue (TALT) is located in the mouse lacrimal sac and shares immunological characteristics with mucosa-associated lymphoid tissues (MALTs), including the presence of M cells and immunocompetent cells for antigen uptake and subsequent generation of mucosal immune responses against ocularly e...
Chronic Helicobacter pylori-stimulated immune reactions determine the pathogenesis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. We aimed to explore the genetic predisposition to this lymphoma and its clinical implication. A total of 68 patients and 140 unrelated controls were genotyped for 84 single-nucleotide polymorphisms in genes encoding cytokines, chemokines and related re...
Mucosa-associated lymphoid tissue (MALT) lymphoma is the third most common non-Hodgkin lymphoma, and it is strongly associated with helicobacter pylori infection of the stomach. MALT lymphoma of the lacrimal gland usually presents as a localized disease process in extranodal tissues. The treatment options of MALT lymphoma of the lacrimal gland chiefly include radiation of the tumor, chemotherap...
Accepted for publication 23 January 1997 Abstract Background-Blood group Lewisb antigens mediate Helicobacter pyloni attachment to gastric mucosa with attachment being particularly strong in subjects with ABH blood group 0. Aims-To determine whether H pyloni colonisation or the occurrence of gastric mucosa associated lymphoid tissue (MALT) lymphomas might be related to gastric Lewisb expression...
The death of cells harboring defects in two distinct pathways implicates these pathways in the control of an essential process. Here we report that cells lacking OmpR and harboring constitutively active MalT undergo premature death that involves increased expression of the outer membrane porin LamB.
PURPOSE Abnormal gastrointestinal permeability (GIP) has been implicated in a number of diseases, including chronic intestinal inflammatory disorders such as Crohn's as well as non-intestinal immunologic diseases such as diabetes and multiple sclerosis. Although evidence in the literature demonstrates mucosal abnormalities of the digestive barrier in asthma, previous studies have assessed only ...
Extranodal marginal zone lymphoma of MALT, previously known as MALT lymphoma, is a low grade B-cell Non-Hodgkin's lymphoma (NHL). Its most frequent locations are the gastrointestinal tract and the lungs while that of the colon is rare. Involvement of multiple mucosal sites is not a frequent finding but it does occur. We describe a case of a 70-year-old man who presented with extranodal marginal...
