Abstract
Background
The spine is the most frequently affected part of the skeletal system to metastatic tumors. External radiotherapy is considered the first-line standard of care for these patients with spine metastases. Recurrent spinal metastases after radiotherapy cannot be treated with further radiotherapy within a short period of time, making treatment difficult. We aimed to evaluate the effectiveness and safety of MWA combined with cementoplasty in the treatment of spinal metastases after radiotherapy under real-time temperature monitoring.
Methods
In this retrospective study, 82 patients with 115 spinal metastatic lesions were treated with MWA and cementoplasty under real-time temperature monitoring. Changes in visual analog scale (VAS) scores, daily morphine consumption, and Oswestry Disability Index (ODI) scores were noted. A paired Student’s t-test was used to assess these parameters. Complications during the procedure were graded using the CTCAE version 5.0.
Results
Technical success was attained in all patients. The mean VAS score was 6.3 ± 2.0 (range, 4–10) before operation, and remarkable decline was noted in one month (1.7 ± 1.0 [P < .001]), three months (1.4 ± 0.8 [P < .001]), and six months (1.3 ± 0.8 [P < .001]) after the operation. Significant reductions in daily morphine consumption and ODI scores were also observed (P < .05). Cement leakage was found in 27.8% (32/115) of lesions, with no obvious associated symptoms.
Conclusion
MWA combined with cementoplasty under real-time temperature monitoring is an effective and safe method for recurrent spinal metastases after radiotherapy.
