strontium chloride Sr 89 The chloride salt of a radioactive isotope of strontium. Strontium chloride Sr 89 is taken up and incorporated preferentially in metastatic lesions in bone where it emits cytotoxic beta radiation, resulting in an inhibition and/or reduction of tumor growth and so tumor-related bone pain. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
