Randomized Controlled Trial Clinical Trial
Multiple daily fractionated radiation therapy and misonidazole in the management of malignant astrocytoma. A preliminary report.
Various attempts have been made to improve the effectiveness of radiation in the treatment of cerebral malignant astrocytomas. A trend favoring multiple daily fractionated (MDF) radiation therapy over conventional single daily fractionated (CF) radiation therapy was identified in our previous study. In order to assess the effect of MDF with and without misonidazole, a province-wide prospective randomized trial was initiated in January 1981. ⋯ The 1-year actuarial survival rate from surgery was 20% for CF group, 41% for MDF group, and 45% for MDF and misonidazole group. There is a statistically significant difference (P less than 0.001) between the CF and MDF group. However, the addition of misonidazole does not significantly alter survival.

The INFUSAID model #400 totally implantable drug delivery system was implanted in 17 patients for the continuous infusion of spinally administered preservative-free morphine sulfate. Sixteen patients had pain of malignant origin, and one patient had pain secondary to meningomyelocele. ⋯ Overall, the patients with cancer were pleased with their pain therapy, experienced few complications, and reported improved quality of life. Continuous infusion of spinally administered narcotics using a totally implantable drug delivery system such as the INFUSAID model #400 is a safe, complication-free procedure for the control of cancer-related pain.
