Vertebroplasty: Integral to Treating Back Pain in Blood Marrow Cancer Patients Reduced Pain and Improved Mobility Gained When Part of Treatment Plan for Vertebral Compression Fractures in Those With Multiple Myeloma Eren Erdem, MD Interventional Neuroradiologist Division Director and Associate Professor University of Arkansas for Medical Sciences The minimally invasive, image-guided treatment of vertebroplasty is an integral component to the complicated treatment of multiple myeloma, an incurable (yet treatable) cancer of the bone marrow that causes destructive lesions in bones and makes them more susceptible to fracture. Vertebral compression fractures are very common in patients with multiple myeloma (up to 70 %) and cause severe pain and debilitation. Patients can experience compression of abdominal contents, decrease in lung capacity, depression, anorexia and reduced ability to perform normal daily functions By reducing pain and improving mobility, vertebroplasty helps patients become better equipped to continue with their rigorous treatment for multiple myeloma • Founded 1989, Bart Barlogie, MD, PhD Epidemiology • 10% hematologic malignancies, 1% all • Incidence 3-4/105, 20,000/year US • 100,000 US patients in treatment • 3:2 Male to female ratio • African-Americans increased risk Multiple Myeloma Uncontrolled overgrowth of plasma cells • Bone marrow failure Anemia Immune dysfunction • Monoclonal Protein Secretion Renal Failure • Increased osteoclast, decreased osteoblast activity Bone destruction Bone Destruction Osteoclast & Osteblast “Un-coupling” SEM courtesy of Dr. Arnett, UCL Secondary osteoporosis Study Objective • Distribution and Extent Vertebral Fractures • Efficacy of Vertebral Augmentation – Pain – Analgesic Usage – Disability Material & Methods • 792 consecutive MM patients • January 2001 through May 2007 • Prospective, IRB-approved study Results n=792 n=440 n=352 mean age 61.6 yrs, SD 10.9 65.6 yrs, SD 13.0 p<0.001 Results Results Results Results Results • Pain Assessment n=520 p < 0.001 Results Results Vertebroplasty Procedure • Under local and intravenous medication • No surgical incision • Needles are placed into the vertebral bone precisely, under advanced live x-ray • The cement is then injected very carefully to stabilize the fracture and alleviate pain • Most procedures are done outpatient and rarely requires limited time in the hospital • There’s no incision, so there’s less pain and less recovery time, only a bandaid • Less expensive than surgery Multiple Myeloma can be very debilitating one month later Pre/Post treatment –Jan 2005 Improved kyphosis When there is no pressure on the spinal cord even the worst fractures can be treated with vertebroplasty Retropulsion Why not open surgery? • Open surgery is the last resort for multiple myeloma and other cancer patients with metastasis to the vertebra • Usually, the bones don’t have enough structure to anchor instruments such as screws and plates • Also, being sick with cancer, these are very aggressive surgeries to handle for the patients Failed back sugery When there is aggressive tumor, interventional radiologists would ablate the tumor at the time of vertebroplasty, to achieve local disease control as well T 11 expansile lesion RFA and Cement injection 5 days post RFA When the patient has many fractures and decompensated, aggressive but safe long procedures can be performed 14 levels treated only two procedures Conclusion Although there is multiple large series of the procedure’s success in osteoporotic patients, this is the first large series on a cancer population of multiple myeloma With increasing experience, interventional radiologists can effectively treat the most complex and difficult cases of compression fractures throughout the spinal column with vertebroplasty
