Abstract
It has been suggested that monoclonal antibodies may be useful in targeting eytotoxie compounds to tumor cells. We have explored their use in targeting 131-I to highly radiosensitive primitive neural tumors such as neuroblastoma and pineoblastomas. Two routes of administration have been employed, intravenous and intrathecal. Our current experience in using radiolabelled antibodies is described, indicating toxicities seen and any therapeutic benefit observed. The results of the study suggest that if targeted radiation has a role in the treatment of these malignancies, it will be restricted to the eradication of small tumor masses from the body.
