摘要：

Primary bladder non-Hodgkin's lymphoma (NHL) is rare. Optimal management remains controversial. Using the Scotland and Newcastle lymphoma group database, 12 patients with primary bladder lymphoma were identified between 1980 and 2001, the largest single group of patients available to date. Histology and immunocytochemistry was reviewed in 9 of the 12 cases. Six cases were low-grade extranodal marginal zone lymphoma, 4 diffuse large B-cell lymphoma, one an ALK 1 positive anaplastic large cell lymphoma (ALKoma) and one a low-grade lymphoma unspecified. Two patients (low-grade NHL) were treated with oral antibiotics (n=1) or diathermy (n=1) alone with complete resolution of disease. One patient with high-grade NHL gained complete remission without conventional therapy. Nine patients were treated with single or combined modality surgery, chemotherapy and/or radiotherapy. Overall survival was 75%, mean follow up of 4.8 (range 1-10) years. A review of 88 additional cases in the literature support the findings that primary bladder lymphoma is associated with a good prognosis. Patients with low-grade extranodal marginal zone lymphoma may respond well to simple therapies. Patients with diffuse large B-cell lymphoma respond well to first-line chemotherapy regimens. Ureteric obstruction and acute renal failure are serious complications. Repeat cystoscopy is mandatory for follow-up.
