Primary gastrointestinal (GI) lymphoma accounts for 2% to 5% of all GI malignancies. Primary therapy in uncomplicated GI lymphoma remains controversial.
Fifty-four patients (male-to-female ratio of 4:3, median age 56 years) with GI lymphoma were studied to evaluate complications and results of therapy. The sites involved were the stomach (31), small bowel (12), large bowel (4), gallbladder (1) and multifocal (6). Distribution by stage and grade (Working Formulation or Kiel) were: IE—30%, IIE—43%, IIIE—6%, IV—20% and unknown—1%; low grade—33%, intermediate grade—59% and high grade—8%. The majority (54%) had diffuse large cell lymphoma.
Twenty-three patients (43%) underwent primary resection of the tumour followed by chemotherapy in 14 or radiotherapy in 3. Seventeen patients (31%) had primary chemotherapy and 3 (6%) had primary radiotherapy. Of the 48 patients who underwent therapy, 52% had a complete response. At the last follow-up (median 21 months), 25 patients were disease-free. Overall survival was 67% at two years.
Treatment strategies employing surgery, radiotherapy and chemotherapy, alone or in combination, do not appear to influence outcome. Surgical resection plus chemotherapy appears to be effective in the control of local and distant disease.
