Non-IPSID small intestinal lymphoma: evidence for disseminated disease at presentation.
During the period 1984-1989 the authors have observed 20 patients with non-IPSID small intestinal lymphomas, 11 males and 9 females. In 11 patients the first symptoms were abdominal cramps requiring laparotomy, in 4 ileus, and in 5 perforation with peritonitis. Resection of the involved part of the intestine was performed in 17 patients. Lymphoma tissue was present in 4 of 5 retrogradely examined resection lines on macroscopically normal small intestine. According to Working Formulation, 3 patients had low grade, 3 intermediate grade and 14 high grade histology. Affection of extra intestinal/mesenteric structures was found in 18 of 20 patients, with a total of 36 other lymphoma localizations. 8 of 20 had affection of the nasopharynx and/or Waldeyer's ring. According to the Crowther's classification 55% of patients were in Stage IV, 35% in Stage III and 10% in Stage Ib. All patients were treated with chemotherapy, 13 with ProMACE regimen and 7 with CHOP-type regimens. Ten of twenty patients are alive and in complete remission for over 5 years (7 of 11 of Stage IV and 3 of 9 of Stage Ib/III; 8 of 14 with high grade and 2 of 6 with intermediate/low grade histology). Our results point to the fact that in non-IPSID lymphoma of the small intestine, lymphoma involvement of the intestinal wall might be present beyond obvious lymphoma lesions. Most patients with apparently primary small intestinal lymphoma have a widespread disease. Thus, local forms of treatment such as surgery, and/or radiotherapy can not be expected to be curative in the majority of patients. Data from this study suggest that following initial surgery the chemotherapy is the treatment of choice for these patients.
