Regression of gastric high grade mucosa associated lymphoid tissue (MALT) lymphoma after Helicobacter pylori eradication.
BACKGROUND Most low grade gastric lymphomas arising from the mucosa associated lymphoid tissue (MALT) are related to Helicobacter pylori colonisation. Cases with disease limited to the stomach can be cured after H pylori eradication and remain in remission for years. In contrast, high grade lymphomas of the stomach, although also related to H pylori, do not usually respond to eradication treatm...
متن کاملFrequency of vacA genotypes and cytotoxin activity in Helicobacter pylori associated with low-grade gastric mucosa-associated lymphoid tissue lymphoma.
The vacA genotypes s1,m1 and s1,m2 were detected in 44 and 30% of Helicobacter pylori isolates, respectively, from patients with gastric mucosa-associated lymphoid tissue lymphoma, compared to 26 and 56% of isolates, respectively, from individuals with gastritis. The vacA s1 genotype was significantly associated with, but not predictive of, the presence of vacuolating cytotoxin activity.
متن کامل[Prognostic impact of Helicobacter pylori infection and eradication therapy in gastric mucosa-associated lymphoid tissue lymphoma].
BACKGROUND Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is associated with Helicobacter pylori infection and H. pylori eradication is used as its first-line therapy. However, controversies exist about the prognostic value of H. pylori infection in these patients. We evaluated the prognostic impact of H. pylori infection and eradication therapy in gastric MALT lymphoma. METHODS A ...
متن کاملLow Grade Gastric Mucosa-associated Lymphoid Tissue Lymphoma: Clinicopathological Factors Associated with Helicobacter pylori Eradication and Tumor Regression
BACKGROUND/AIMS Eradication of Helicobacter pylori is widely accepted as initial therapy for low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, approximately 20% of patients with this disease are not responsive to H. pylori eradication therapy. The aim of this study was to assess remission and relapse rates of low-grade gastric MALT lymphoma after H. pylori eradicatio...
متن کاملSimultaneous occurrence of gastric adenocarcinoma and low-grade gastric lymphoma of mucosa-associated lymphoid tissue.
Gastric adenocarcinoma developing concomitantly with a gastric lymphoma of the mucosa-associated lymphoid tissue (MALT) type is rare. Herein, we report a case with a synchronous primary gastric MALT lymphoma and an early adenocarcinoma of the stomach. A 72-year-old patient with initial presentation of weight loss was found with endoscopy to have a large tumor mass in the gastric body. Pathologi...
