Primary gastrointestinal non‐Hodgkin's lymphoma in adults: a population‐based clinical and histopathologic study. J Intern Med 1998; 244 : 71–8. Objectives To analyse the clinical course and the histopathology of primary gastrointestinal non‐Hodgkin's lymphoma (GI‐NHL) in adult patients and to investigate a possible impact of Helicobacter pylori . Design/setting Retrospective study of all adult patients in Copenhagen county diagnosed during a 6‐year period with NHL. Subjects A total of 55 patients with GI‐NHL diagnosed during the period from 1985 to the end of 1990. Results Twenty‐eight patients had primary lymphoma in the stomach, 14 in the small intestine, 11 in the large intestine and two patients had multifocal involvement. The dominant presenting symptoms were abdominal pain, weight loss, diarrhoea, constipation and fatigue. Acute emergency problems such as severe haemorrhage or perforation at initial presentation were unusual. According to the revised European‐American lymphoma (REAL) classification, diffuse large B‐cell lymphoma was the most frequent histologic subtype comprising 53% of the cases. Helicobacter pylori infection was documented in 15 of 25 evaluable patients (60%) with gastric lymphomas and was not associated with any specific histological subtype. Endoscopic procedures and barium X‐rays were the diagnostic approaches with highest sensitivity. In total, 30 patients (58%) achieved complete remission, 10 (19%) achieved partial remission, and 12 (23%) did not respond to treatment. The overall 5 year survival rate was 0.36 without statistically significant difference between the histological subtypes. Likewise the presence of Helicobacter pylori did not affect survival. Conclusion Primary GI‐NHL is a heterogeneous disease entity with considerable therapeutic controversies. No specific clinical or histological phenotype was associated with the presence of Helicobacter pylori .
