Mucosa-associated lymphoid tissue (MALT) variant of primary rectal lymphoma (Kelley SR. Int J Colorectal Dis 2016)
RESULTS: Fifty-one cases were identified. A complete response was achieved in 12 of 19 cases treated with Helicobacter pylori eradication therapy, 5 of 6 with radiation, 2 of 4 cases with chemotherapy, 2 of 4 with endoscopic resection, 6 of 8 cases with surgical resection, and all 8 with combination therapies. Cases failing initial therapies were responsive to various second-line treatments. Two cases spontaneously regressed with observation alone.
DISCUSSION:
Extranodal MALT lymphomas are unique tumors that usually arise in organs devoid of lymphoid tissue. Sixty to 70 % of extranodal MALT lymphomas occur in the gastrointestinal tract with the stomach being the most commonly involved (50-60 %) followed by the small intestine (30 %) and the colon and rectum (6-12 %)
It has been postulated that the presence of gastric H. pylori likely has no impact on colorectal MALT. It has been suggested that infection with microorganisms other than H. pylori may be responsible for the induction and growth of MALT lymphoma outside of the stomach. MALT lymphoma of the small intestine has been associated with Campylobacter jejuni, skin with Borrelia burgdorferi, and orbit Chlamydia psittaci. Antibiotics used to eliminate H. pylori may eradicate other unknown organisms that are involved in the development of primary rectal MALToma.
