HELICOBACTER PYLORI ANO MARGINAL ZONE B-CELL GASTRIC LYMPHOMA OF MALT TYPE
Keywords:
lymphoma, lymphoma, mucosa-associated lymphoid tissue, imuno histochemistry, geneticsAbstract
Marginal zone 8-cell lymphomas of mucosa-associated lymphoid tissue (MALT lymphoma) comprise up to 50% of primary gastric lymphomas. lt is frequent the association between Helicobacter pylori and some gastric tumors, such as adenocarcinoma and of MALT lymphoma. Therefore, patients presenting gastric MALT lymphoma, are usually submitted to an eradication treatment of H. pylori. However, it is vital to consider some cases in which the clinica! treatment for eradication of this bacterium is ineffective. Generally, the low-grade gastric MALT lymphoma has an indolent evolution, so that an accurate and timely diagnosis may offer a cure through surgical treatment. This article describes an advanced gastric MALT case, which was unresponsive to clinica/ treatment for H. pylori. lt also reviews current concepts on pertinent treatment for this binomial (tumor-infectious agent).
