Abstract

PURPOSE: To report the treatment outcomes of patients with metastatic bone disease with complete or impending pathologic fractures, who were treated with postoperative radiotherapy (RT), bisphosphonates or both after orthopedic stabilization.

MATERIAL AND METHODS: We retrospectively evaluated the results of RT, bisphosphonates or both after orthopedic stabilization for complete or impending pathologic fractures in 72 patients with skeletal metastases. After surgery, 32 patients (44%) were treated with RT alone (group 1), 31 patients (43%) were treated with RT and bisphosphonates (group 2) and 9 (13%) patients were treated with bisphosphonates (group 3), respectively. Patients were treated with a median dose of 30Gy (30-40 Gy/2-3Gy per fraction).The local tumor progression, pain progression and need for re-operation or re-radiotherapy were assessed from patients' medical records. Median follow-up time was 9 months.

RESULTS: Median overall survival time was 14 months (95% CI: 12-17). Secondary surgical intervention at the same location was necessary in 1 patient of group 1 (2%), 2 patients of group 2(5%) and 2 patients of group 3 (15%), respectively (p=0.097). Local tumor progress was observed in 3 patients of group 1 (9%), 2 patients of group 2 (7%) and 4 patients in group 3 (44%), respectively (p=0.021). Local pain progress was observed in 19%, 16% and 67% of the same groups (p=0.011).

CONCLUSION: Our data confirm the efficacy and necessity of postoperative RT after orthopedic stabilization for metastatic bone disease to control the local disease. Bisphosphonates do not obviate the need for RT in the management of bone metastases after surgical stabilization. The combined treatment might lead to a better local tumor and pain control.
