Abstract

This study aimed to examine the efficacy and safety of cryoablation, combined with zoledronic acid or alone, in the treatment of bone metastatic pain. A total of 84 patients were randomly divided into three groups: group A (cryoablation plus zoledronic acid), group B (cryoablation) and group C (zoledronic acid). In group A, the overall response [OR = complete response (CR) + partial response (PR)] was 85.7% (24/28), the CR was 35.7% (10/28) and the PR was 50.0% (14/28). In group B, the OR was 50.0% (14/28), the CR was 14.3% (4/28) and the PR was 35.7% (10/28). In group C, the OR was 67.9% (19/28), the CR was 21.4% (6/28) and the PR was 46.4% (13/28). The differences in OR, CR and PR among the three groups were statistically significant (P<0.05). The mean onset time of pain relief for the cryoablation combined with zoledronic acid treatment group was 1.96±2.26 days, for cryoablation treatment alone was 1.43±1.79 days and for zoledronic acid alone was 11.67±3.14 days; there were statistically significant differences among the three groups (P<0.05). The response duration was 146.68±1.89 days in group A, 71.60±2.94 days in group B and 112.99±1.37 days in group C; the differences among the three groups were statistically significant (P<0.01). In conclusion, cryoablation combined with zoledronic acid is an effective and safe therapeutic strategy for the treatment of bone metastatic pain.
