pubmed:abstractText |
Normal gastric mucosa is devoid of lymphoid cells. Any increase of lymphocytes suggests chronic inflammation. Infection with Helicobacter pylori (Hp) is the major cause for nonautoimmune chronic gastritis and induces a mixed cellular response resulting in an acquired lymphoid tissue, or MALT (mucosa-associated lymphoid tissue). Hp has also been implicated in the genesis of gastric MALT-lymphoma. Polymerase chain reaction-based assays to detect the expansion of monoclonal B-cells have also been used to corroborate the diagnosis. In a considerable number of cases monoclonal B-cells remain detectable in follow-up biopsies, with the lymphoma being in complete histological remission. The clinical relevance of this finding is not clear yet. However, there also exist different reports that monoclonal B-cells can be found in gastric biopsies of patients with neither a histological sign nor a present or past history of lymphoma. In the light of these findings we address the question whether B-cell monoclonality can be seen as a premalignant condition in chronic gastritis and conclude that as of now the relevance of the finding of B-cell monoclonality remains unclear. As of now the only and gold standard for the diagnosis of gastric MALT-lymphoma is histopathology.
