Purpose:
The aim of this study was to investigate the clinical factors related to hematologic toxicity caused by treatment with samarium-153 ethylenediaminetetramethylene phosphonic acid (153Sm-EDTMP).
Materials And Methods:
A total of 206 secondary bone neoplasm patients treated with 153Sm-EDTMP were analyzed retrospectively. Logistic regression (SPSS 10.0 for Windows; Chicago, IL) and correlation analysis were used to evaluate the factors concerned.
Results:
Age, number of bone metastatic lesions, chemotherapy before treatment with 153Sm-EDTMP, concurrence of radiotherapy, and times of repeated treatments with 153Sm-EDTMP were determined by single factor analysis to be related to hematologic toxicity. Chemotherapy before treatment with 153Sm-EDTMP, concurrence of radiotherapy, drug use to maintain normal white blood cell counts, and times of repeated treatments with 153Sm-EDTMP were determined by multiple factor analysis to be related to hematologic toxicity.
Conclusions:
Chemotherapy before treatment with 153Sm-EDTMP, concurrence of radiotherapy, drug use to maintain normal white blood cell counts, and times of repeated treatments with 153Sm-EDTMP are the main clinical factors related to hematologic toxicity caused by 153Sm-EDTMP therapy. In patients with such factors, more attention might be paid to the change of blood cell counts after 153Sm-EDTMP therapy.

In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
