Large solid tumore might need betas to penetrate the amss of the tumor. Only a handful of successful marriages of radioisotope to antibody have been made so far. So far, they have used it on teens and adults scheduled to receive bone marrow transplants to arrest advanced leukemias. This is okay for adults and teens, but young children need a parent's touch. The radiation emitted from this isotope travels only about 3-5 cell diameters.
Most antibody therapies are particularly successful against leukemias as opposed to solid tumors.
These cancers are generally smaller and more sensitive to radiation poisoning than solid tumors and they are bathed in the blood that can ferry the injected isotopes. Thus, Vriesendorp notes, oncologists have adopted a 'no pain, no gain' philosophy. No references to journal articles were given. A Clue to Leukemia First, a little background. Scientists have known since the 1950s and 1960s that tumor cells have unusual chromosomes.
