Overview
Gastric lymphoma refers to malignant neoplasms originating in the stomach, predominantly classified as non-Hodgkin lymphomas, often associated with mucosa-associated lymphoid tissue (MALT). 9Diagnosis
Clinical Presentation: Epigastric pain, upper abdominal discomfort, and presence of a palpable mass. 3
Laboratory Tests: Elevated inflammatory markers, anemia (including vitamin B12 deficiency), and achlorhydria may be observed. 4
Imaging: CT scans and endoscopic ultrasound to assess tumor size, local invasion, and staging.
Endoscopy: Essential for obtaining biopsies; histopathological examination confirms diagnosis. 3
Helicobacter pylori Testing: Serology or urea breath test to assess for previous infection, which may be relevant in pathogenesis. 245
Immunohistochemistry: Correlates with histopathology to identify specific subtypes, often showing follicle center cell lymphomas. 89Management
First-Line Treatment: Chemotherapy regimens such as CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) are commonly used. 6
Surgical Intervention: Limited evidence suggests surgery alone has minimal impact on prognosis; considered adjunctive in specific cases. 1
Antibiotics: For concurrent Helicobacter pylori infection, antibiotic therapy may be beneficial, especially in pediatric cases. 5
Targeted Therapy: Not extensively detailed in abstracts but may be considered based on specific molecular markers.
Supportive Care: Management of symptoms, nutritional support, and monitoring for complications like achlorhydria and vitamin deficiencies. 4Special Populations
Pediatrics: Aggressive treatment is warranted due to rarity and potential for long-term survival; consider Helicobacter pylori as a predisposing factor. 256
Elderly: Specific considerations for comorbidities and treatment tolerance are necessary, though not extensively detailed in abstracts.
Comorbidities: Management of concurrent Helicobacter pylori infection may influence outcomes positively, particularly noted in pediatric and adult cases. 245Key Recommendations
Primary Treatment with Chemotherapy: Use CHOP or equivalent regimens as first-line therapy for gastric lymphoma. (Evidence: Strong 6)
Consider Helicobacter pylori Status: Evaluate and treat Helicobacter pylori infection, especially in pediatric patients, as it may influence disease progression. (Evidence: Moderate 25)
Role of Surgery: Surgery may be considered adjunctively but does not significantly impact overall survival; high-quality trials needed for definitive guidance. (Evidence: Weak 1)References
