A retrospective analysis was performed on 72 patients with disseminated skeletal matestasis to evaluate the effect of strontium?89 or samarium?153 EDTMP therapy. There existed 87.88% of clinical response
12.12% of no response in the group treated with strontium?89 as compared with 90.24% of clinical response
9.76% no response in that treated with samarium?153 EDTMP; and there were no correlations between the treatment results and the amounts of isotopes administrated. The results suggest that strontium?89 or samarium?153 EDTMP therapy be the first choice in the palliative treatment for disseminated skeletal matestasis.
