Summary
Radiofrequency thermal ablation (RFA) effectively treats chondroblastoma, achieving 100% pain control. Imaging shows successful ablation and bone stability, with minimal long-term complications.
Area of Science:
- Orthopedic Oncology
- Interventional Radiology
- Musculoskeletal Tumors
Background:
- Chondroblastoma is a rare, benign bone tumor typically affecting adolescents.
- Traditional treatments can be invasive and may lead to significant morbidity.
- Radiofrequency thermal ablation (RFA) offers a minimally invasive therapeutic option.
Purpose of the Study:
- To evaluate the efficacy and safety of RFA for chondroblastoma treatment.
- To present our experience with CT-guided RFA in a case series of chondroblastoma patients.
Main Methods:
- A case series of 12 patients with chondroblastoma treated with CT-guided RFA.
- Tumor locations included humeral head, femoral head, distal femoral epiphysis, tibial epiphysis, and calcaneus.
- Both dry and perfused ablation modes were utilized, with cementation in 5 cases.
Main Results:
- Technical success was achieved in 83% after the first RFA session, with 100% clinical success after a second treatment if needed.
- Follow-up MRI confirmed edema resolution and necrosis beyond the tumor margins in most cases.
- Radiography and CT demonstrated lesion stability and cortical integrity, with rare long-term complications.
Conclusions:
- RFA is a successful treatment modality for chondroblastoma, achieving excellent pain control.
- Cementoplasty enhances structural integrity in weight-bearing areas post-ablation.
- MRI findings of edema resolution and necrosis, alongside radiographic stability, correlate with successful outcomes.
