Summary
Early diagnosis of gastric MALT lymphomas is crucial. Histological examination of gastric mucosa in Helicobacter pylori (HP) positive patients is the most effective method for detecting early-stage, curable lesions.
Area of Science:
- Gastroenterology and Oncology
- Pathology and Infectious Diseases
Background:
- Non-invasive tests for Helicobacter pylori (HP) detection can delay early lymphoma diagnosis.
- Successful HP eradication leads to regression of gastric low-grade MALT lymphomas, underscoring the need for early detection.
Purpose of the Study:
- To analyze the clinical, endoscopic, histopathologic, and immunohistochemical features of gastric MALT lymphomas.
- To emphasize the importance of histological examination for early gastric MALT lymphoma detection in HP-positive patients.
Main Methods:
- Retrospective analysis of twenty-seven consecutive cases of gastric MALT lymphoma.
- Assessment of HP presence in gastric mucosa using histological examination.
- Correlation of endoscopic findings with suspected malignancy diagnosis.
Main Results:
- HP infection was detected in 100% of gastric MALT lymphoma cases.
- Endoscopic diagnosis of suspected malignancy was only achieved in 40.7% of cases.
- Histological examination proved essential for identifying HP in all patients.
Conclusions:
- Histological examination of gastric mucosa is the most effective tool for diagnosing early-stage, curable gastric MALT lymphomas.
- Sampling gastric mucosa in HP-positive patients is critical for timely diagnosis and treatment initiation.
