title: An update on therapeutic uses of radiotracers in neoplastic disease.
abstract: The key to delivering radiation to a lesion by means of internally administered radiopharmaceuticals is specificity of localization (a high lesion-background ratio). Factors that may limit this localization are pointed out. Potential alteration of the residence time within the lesion and use of radiation-sensitizing agents may bring new applications for radionuclides in therapy. The most common therapeutic applications of radiopharmaceuticals are outlined.
