Abstract
As a treatment of patients with intractable cancer and noncancer pain, bilateral radiofrequency cingulotomy was performed in 10 patients. The technique involved stereotaxis using magnetic resonance guidance and local anesthesia, with the placement of a radiofrequency lesion (75 degrees, 60s). Of the 10 patients, 8 had metastatic lesions with musculoskeletal (6) or neurogenic (2) pain. Pain relief was judged excellent (4 patients), fair (1), poor (2) and excellent for 6 months poor in the last patient. The two benign lesions were neurofibromatosis with neurogenic pain and thalamic pain from an old stroke. Pain relief (with 1 year follow-up) in this group was judged excellent in one and poor in the other (thalamic pain).
