20110135569 | METHOD FOR THERAPEUTIC ADMINISTRATION OF RADIONUCLEOSIDES - Methods are provided for the local radiotherapy of cancers such as locally invasive, advanced stage solid tumors, and normal tissues penetrated by processes of cancerous tissue, through administration of Auger-electron emitting radionucleoside analogs using high-flow microinfusion techniques (“convection-enhanced delivery”). Direct infusion under pressure, at flow rates in excess of at least about 0.5 microliters/min of the radionucleosides provides for their mass transport through tissue to a much higher degree than could be achieved by passive, unpressurized diffusion. The unique properties of these radionucleoside analogs that provide for surprisingly effacacious delivery by high-flow microinfusion include rapid clearance from tissues following local injection without the benefit of sustained high-flow microinfusion, rapid and complete clearance via the blood stream, poor permeation of barriers such as the blood-brain barrier, and a highly potent, non-selective, but very short range killing effect on cells that are undergoing DNA replication that incorporate radionucleosides into their chromosomes. | 06-09-2011 |
