Abstract

Ten patients with non-Hodgkin's lymphoma have been evaluated as candidates for experimental radioimmunotherapy and five of those patients have been treated with a single high dose of iodine-131-(131I) labeled anti-pan B-cell antibodies. The evaluation protocol involved collecting biodistribution data by quantitation of gamma camera images and by tumor biopsy from trace labeled doses of antibody, to estimate the relative radiation dose delivered to normal organs and tumor sites. Each patient received up to three escalating mass doses (0.5 mg/kg, 2.5 mg/kg, and 10.0 mg/kg) of radioiodinated antibody for determination of the antibody amount that yielded the most favorable biodistribution for treatment. The millicuries of 131I-labeled to the optimal antibody dose for therapy was selected to deliver 1,000 rads (three patients) or 1,500 rads (two patients) to normal uninvolved organs. Because severe bone marrow toxicity was expected, all patients had their bone marrow cryopreserved prior to entry into the study. This report details the methods and results of quantitative imaging, biodistribution data collection, and absorbed radiation dose estimation in patients with lymphoma receiving high level radioimmunotherapy with 131I-labeled antibodies.
