Medical device developer DFine is directing attention to research presented at last week's American Society of Spine Radiology (ASSR) annual symposium.
The study, presented by Dr. Bassem Georgy, of the University of California, San Diego, found that use of DFine's Star tumor ablation system improved pain relief and functional status in patients treated for malignant lesions of the spine, DFine said.
Targeted radiofrequency ablation with Star was used to treat 34 spinal lesions in 22 patients with varied malignancies. Postablation MRI and PET scans revealed decreased tumor volume and metabolic activity, according to the company.
In addition, clinically significant pain relief -- greater than 30% change -- was reported, and function also improved. No complications or thermal injury were reported from the procedures, DFine said.
