Percutaneous cementoplasty for pelvic bone metastasis

Area of Science:

• Oncology
• Radiology
• Orthopedic Surgery

Background:

• Pelvic bone metastases frequently cause significant pain and functional impairment in cancer patients.
• Conventional treatments like radiotherapy may not always provide adequate pain relief or may be contraindicated.
• Percutaneous cementoplasty is an emerging interventional technique for managing bone metastases.

Purpose of the Study:

• To evaluate the effectiveness and safety of percutaneous cementoplasty for treating pain associated with pelvic bone metastases.
• To assess the impact of cementoplasty on pain reduction and functional improvement in cancer patients with pelvic lesions.

Main Methods:

• A retrospective analysis of a multicenter prospective database involving 18 cancer patients (average age 58) who underwent percutaneous cementoplasty.
• Procedures were guided by computed tomography (CT) or fluoroscopy.
• Indications included pain recurrence or lack of relief after radiotherapy, or as a pre-radiation intervention.

Main Results:

• The study included metastases in the acetabulum (n=12), iliac bone (n=2), and sacrum (n=4).
• A significant improvement in pain and walking ability was observed in 81.8% of patients.
• Pain relief was generally maintained throughout the follow-up period (mean 4.6 months), with one exception due to fracture.

Conclusions:

• Percutaneous cementoplasty is a safe and effective minimally invasive treatment for pelvic bone metastases.
• The procedure provides rapid pain resolution and functional improvement, particularly when radiotherapy fails or is not feasible.
• Cementoplasty represents a valuable therapeutic option for improving the quality of life in cancer patients with painful bone metastases.
