Radioimmunoglobulin therapy is a new treatment modality that is easily administered, well tolerated, and can be given on an outpatient basis. It is not, however, as simplistic an approach to cancer therapy as commonly thought. It incorporates the sciences of immunology, physiology, radiobiology, chemistry, and physics, as well as oncology, all of which must be understood if radioimmunoglobulin therapy is to reach its potential. Partial and complete remissions have been achieved while the clinical teams involved in this research are still in the process of defining materials, methods, and future clinical approaches. The authors enumerate the varied problems in the development of radioimmunoglobulin therapy, and report on the current status of clinical trials.

High-dose radiation therapy for liver metastases of gastrointestinal malignancies might be improved by combining external-beam irradiation and radioimmunoglobulin therapy. We studied the liver toxicity of the proposed combination in healthy beagle dogs. A total dose of 30 Gy to the whole liver, delivered in 2-Gy fractions over 3 weeks, resulted in mild, temporary veno-occlusive disease (VOD) in three of three dogs.

The mutagenic impact of various environmental and therapeutic agents can now be directly assayed in humans by the T-lymphocyte cloning assay. We have previously reported that following radioimmunoglobulin therapy, cancer patients exhibited increased mutant frequency of the hprt locus and an increased yield of large intergenic deletions compared to unexposed controls. Here we report the results of the analysis of 26 independent hprt mutations in nine cancer patients who underwent radioimmunoglobulin therapy.

Using a multidisciplinary approach, we have measured various indicators of DNA damage in peripheral lymphocytes of human populations potentially at increased risk for cancer. Sister chromatid exchanges (SCE) and polycyclic aromatic hydrocarbon (PAH)-DNA adducts were evaluated in a group of firefighters; chromosomal aberrations and hprt mutations were evaluated in a group of cancer patients undergoing radioimmunoglobulin therapy (RIT); SCE and acrolein-modified DNA were measured in cancer chemotherapy patients and in pharmacists preparing chemotherapy prescriptions; and SCE and PAH-DNA adducts are being measured in U.S.

B72.3, a monoclonal antibody with reactivity against human adenocarcinomas, was coupled with linker-chelator GYK-DTPA using carbohydrate mediated conjugation chemistry and radiolabeled with yttrium-90. Single and double intravenous injections of radioimmunoconjugate were compared for acute and late normal tissue toxicity in 15 beagle dogs.

Promising response rates are noted in patients with refractory Hodgkin's disease after radioimmunoglobulin therapy (RIT) with Yttrium-90 labeled polyclonal antiferritin. To explore the most efficacious selection of RIT reagents for use in humans, experimental animal data are reviewed for radiolabeled antiferritin and B72.3.
