Primary gastrointestinal non-Hodgkin's lymphoma: a study of 35 patients

In a retrospective study of 35 patients (29 men, 6 women) with primary non-Hodgkin's lymphomas of the gastrointestinal tract, 13 of the tumours were located in the stomach, 21 in the small bowel and one in the colon. Various radiological findings were detected, and the majority of tumours (23) had high grade histology. Three patients had immunoproliferative small intestinal disease. Only tumours in stages I and II were included in the study, and the majority (25) were in stage IIA. All patients except one had undergone resection of the neoplasm. This was followed by combined chemotherapy in 25 patients, and chemotherapy followed by radiotherapy in three cases. There were two (5.7%) hospital mortalities. Two- and 5-year survival rates were better in those patients with low stage and low grade tumours. The overall 5-year survival rate was 38%.
