title: Ultrasonography-guided radiofrequency ablation of malignant musculoskeletal soft-tissue tumors using the "moving-shot" technique at a single-institution experience.
abstract: The present study describes the use of the "moving-shot" technique for successful radiofrequency ablation (RFA) of malignant musculoskeletal soft-tissue tumors. Ultrasonography-guided RFA was performed in 6 malignant soft-tissue tumors in 5 patients. Short-term follow-up after RFA (8-27 weeks) showed that complete necrosis was achieved in all lesions, and 5 lesions (83%) decreased in size. Discomfort caused by the tumors decreased subjectively in all patients after ablation. Our results indicate that ultrasonography-guided RFA using the moving-shot technique can be an effective treatment option for locoregional control of malignant soft-tissue tumors. Long-term follow-up studies with a larger number of patients are necessary.
