Abstract
PURPOSE: To assess safety and efficacy of percutaneous cryoablation for pain palliation of metastases to pleura and chest wall. MATERIALS AND METHODS: This retrospective single-center cohort study included 22 patients (27% female, mean age 63 y ± 11.4) who underwent 25 cryoablation procedures for pain palliation of 39 symptomatic metastases measuring 5.1 cm ± 1.9 (range, 2.0-8.0 cm) in pleura and chest wall between June 2012 and December 2017. Pain intensity was assessed using a numerical scale (0-10 points). Statistical tests t test, χ2, and Wilcoxon signed rank were performed. RESULTS: Patients were followed for a median of 4.1 months (interquartile range [IQR], 2.3-10.1; range, 0.1-36.7 mo) before death or loss to follow-up. Following cryoablation, pain intensity decreased significantly by a median of 4.5 points (IQR, 2.8-6; range, 0-10 points; P = .0002 points, Wilcoxon signed rank). Pain relief of at least 3 points was documented following 18 of 20 procedures. Pain relief occurred within a median of 1 day following cryoablation (IQR, 1-2; range, 1-4 d) and lasted for a median of 5 weeks (IQR, 3-17; range, 1-34 wk). Systemic opioid requirements decreased in 11 of 22 patients (50%) by an average of 56% ± 34. Difference in morphine milligram equivalents was not significant (P = .73, Wilcoxon signed rank). No procedure-related complications occurred despite previous radiation of 7 tumors. Of 25 procedures, 22 (88%) were performed on an outpatient basis. CONCLUSIONS: Percutaneous cryoablation for metastases to pleura and chest wall can safely provide significant pain relief within days following a single session.
