Malignant intestinal non-Hodgkin's lymphoma from the surgical point of view

Primary intestinal non-Hodgkin's lymphoma (I-NHL) is much less frequent than gastric lymphoma and has hardly been studied in prospective trails. To the surgeon, patients frequently present with abdominal emergencies.

A consecutive series of patients subjected to surgery because of I-NHL between 1998 and 1999 was evaluated retrospectively for characteristic clinical, radiographic and intraoperative findings. Patients with gastric lymphoma were not considered.

10 patients, 8 males and 2 females, with I-NHL were subjected to first-line surgery because of painful abdominal tumor, intestinal hemorrhage, obstruction or perforation. I-NHL was located most often in the small bowel (n = 7). It was rare in the colon (n = 2) and the duodenum (n = 1). Median postoperative follow-up was 28 months. Perioperative mortality was 10% (n = 1). Probability of survival 3 years after surgery was 60%.

Patients with I-NHL frequently present with complications of tumor growth, requiring urgent surgical treatment. Irrespective of surgical complications we advocate surgery in cases of resectable disease as first-line treatment. Adjuvant treatment is indicated with respect to resection status and histopathological staging.
