Abstract
Osseous metastases to the spine result in significant pain and decreased quality of
life. The purpose of this study was to evaluate the long-term efficacy of microwave
ablation (MWA) for the treatment of spinal metastases regarding pain reduction and
local control of disease progression. In this single center retrospective study, patients
with osseous metastases to the spine undergoing MWA with vertebroplasty from 2013
to 2020 were included. Locoregional control of metabolic activity at the treated level
was assessed using PET/CT scan both pre- and post-procedure. Pain reduction was measured
using change in visual analog scale (VAS) pain score. Forty-eight spinal levels were
treated with MWA in 28 patients (57 % male, mean age 68 ± 9 years). Median ablation
time, energy, and temperature were 4 min and 13 s, 3.6 kJ, and 80 °C, respectively.
Median pre-procedure maximum standard uptake value (SUVmax) was significantly reduced
following ablation, from 4.55 (IQR 3.65–6.1) to 0 (IQR 0–1.8; p < 0.001), over an
average of 29 ± 14.1 month follow up period. Pre-procedure VAS pain score was reduced
from median (IQR) of 8 (6.5–9) to 1(1–2), 2(1–3) and 1(0.5–3) at 24 h, four weeks,
and six months post-procedure, respectively (all p < 0.001 with respect to pre-procedure
scores). In conclusion, this study supports microwave ablation as an effective technique
for pain palliation and long-term locoregional tumor control of oligometastatic spinal
disease as assessed by metabolic response.
