A prospective trial to demonstrate the efficacy of intrathecal baclofen therapy by implanted pump for adults with spasticity due to spinal cord injury or multiple sclerosis was initiated in our hospital. Of the 140 patients assessed, 7 met the following criteria for inclusion in the study: a modified Ashworth score > 3, a spasm frequency score > 2, and an inadequate response to oral anti-spasticity drugs, (i.e., baclofen, clonidine and cyproheptadine). All patients responded to intrathecal bolus injection of baclofen in the double blind, placebo-controlled screening phase (mean bolus dose = 42.8 micrograms). ⋯ The cost of in-hospital implantation as well as the cost of the pumps were deducted from the gross savings. There was a net cost-saving of $153,120. Our findings agree with the reported efficacy and safety of intrathecal baclofen treatment, and illustrate the cost-effectiveness of this treatment.

Of 112 stereotactic high-activity iodine-125 implants for malignant brain tumors done as of July 1, 1994, ten have been done for recurrent single brain metastasis and constitute the study group described herein. All patients had initially undergone craniotomy for tumor resection followed by fractionated external beam whole brain radiation and recurred at the same site in the brain. The interval between initial cancer therapy and occurrence of the brain metastasis was 13-156 weeks (median: 63 weeks). ⋯ Five died of recurrence of the brain metastasis at 20, 39, 52, 103, and 143 weeks post-implant, and one died of systemic metastases at 40 weeks post-implant. Two patients remain alive 183 and 324 weeks post-implant. High-activity iodine-125 brachytherapy appears to be of benefit for selected patients with recurrent single brain metastasis but larger, and preferably randomized studies are needed.
