To support physicians when selecting individualized programs for these patients, a simple instrument for predicting survival was created. Patients and Methods: In 126 female patients with breast cancer irradiated for bone metastases, 11 characteristics were evaluated with respect to survival. Results: On Cox regression analysis, Eastern Cooperative Oncology Group performance score (0-1 vs. >=2; p=0.032) and visceral metastases (absence vs. presence; p=0.017) were independently associated with survival and incorporated into the scoring instrument. Three prognostic groups (0, 1 or 2 points) were designated with 12-month survival rates of 38\%, 57\% and 91\%, and 24-month survival rates of 32\%, 36\% and 80\%, respectively (p\<0.001). Conclusion: This easy-to-use scoring instrument allows physicians to estimate the lifespan of patients irradiated for bone metastases from breast cancer and can facilitate individualization of their treatment.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/40/1/367}, eprint = {https://ar.iiarjournals.org/content/40/1/367.full.pdf}, journal = {Anticancer Research} }
