- Experience in using rapidly internalizing antibodies, such as the anti-CD22 antibody, for radioimmunotherapy of B-cell lymphomas is still limited. The present study was conducted to assess the efficacy and toxicity of a 131I-labeled anti-CD22 monoclonal antibody (mAb), LL2, in patients with B-cell lymphomas failing first- or second-line chemotherapy. Eligible patients were required to have measurable disease, less than 25% B cells in unseparated bone marrow, and an uptake of 99mTc-labeled LL2Fab' in at least one lymphoma lesion on immunoscintigram. Eight of nine patients examined with immunoscintigraphy were unequivocally found to have an uptake, and therapy with 131I-labeled anti-CD22 [1330 MBq/m2 (36 mCi/m2)] preceded by 20 mg of naked anti-CD22 mAb was administered. Three patients achieved partial remission (duration, 12, 3, and 2 months), and one patient with progressive lymphoma showed stable disease for 17 months. Four patients exhibited progressive disease. The toxicity was hematological. Patients with subnormal counts of neutrophils or platelets before therapy seemed to be more at risk for hematological side effects. Radioimmunotherapy in patients with B-cell lymphomas using 131I-labeled mouse anti-CD22 can induce objective remission in patients with aggressive as well as indolent lymphomas who have failed prior chemotherapy.

- In a retrospective study of 213 patients with high-grade non-Hodgkin's lymphomas clinical stage I, diagnosed 1985-1990, pretreatment prognostic variables and result of treatment were analysed. The median age of the patients was 67 years. Treatment consisted of radiotherapy in 61%, chemotherapy (10%) chemotherapy followed by radiotherapy (23%) and surgery alone (5%) of the patients. Complete response was achieved in 89% of the patients with estimated relapse-free survival at 5 years of 73%. Relative 5-year survival of all patients was 73%. After chemotherapy followed by radiotherapy the relapse rate was 15% compared with 29% after radiotherapy only. The 5-year relative survival differed between 58% and 74% in the treatment groups. Age, sex, nodal versus extranodal lymphoma, systemic symptoms, bulk of tumor and level of serum lactic dehydrogenase (s-LDH) were analysed as prognostic factors. In multivariate variate analysis, only age 65 years or older and elevated s-LDH were significant independent adverse prognostic factors.
