Evaluation of Efficacy of 153Sm-EDTMP in Patients with Painful Bone Metastases of Breast Cancer

Objective To explore the therapeutic efficacy of 153 Sm EDTMP in treating painful bone metastases from breast cancer. Methods Seventy six patients with painful bone metastases from breast cancer entered the study and were treated by intravenous administration of 153 Sm EDTMP in two doses. Results Overall, 65 of 76 patients (85.52%) experienced prompt pain relief; among them 25 patients (32.89%) felt complete remission and 40 patients (52.63%) met with moderate remission. Follow up imaging examinations were performed after each course of treatment. Complete metastatic foci disappearance was achieved in 6 cases and partial metastatic foci disappearance or regression was achieved in 16 cases, so the global effective rate was 28 95%. No major adverse effects were observed, and hematological toxicity did not exceed grade 3 in accordance to the World Health Organization criteria. Conclusion 153 Sm EDTMP is safe and effective for fast palliation of painful bone metastases and for inhibition of metastatic foci from breast cancer.
