| Outline of Final Research Achievements |
This prospective study enrolled 20 subjects (15 male, 5 female) with mean age of 64.8 years (range, 52-85 years) having malignant musculoskeletal tumors with a mean maximum diameter of 2.9 cm (range, 1.0-4.7cm). No adverse event was found in 18 of 20 patients (90%). Grade-3 peripheral nervous system disorder was fund in 2 patients (10%, 2/20). NRS scores fell down to 0 in 3 of 3 patients (100%) who had painful musculoskeletal tumors. Tumor response (complete or partial response) was achieved in 19 of 20 patients (95%) during follow-up period. The 5-year overall survival rate and the median survival time were 27.4% and 4.4 years, respectively.
In conclusion, cryoablation for musculoskeletal tumors is relatively safe, feasible, and useful therapeutic option for controlling tumors and for relieving pain, which can engender prolonged patient survival.

骨軟部腫瘍に対するCTガイド下凍結療法は、比較的安全で、良好な局所腫瘍壊死や除痛効果が得られ、予後延長の可能性も期待されると思われた。
