High Dose Rate Prostate Brachytherapy as Salvage for Locally Recurrent Prostate Cancer Previously Treated With External Beam Radiotherapy

2014-08-27 03:33:21 | BioPortfolio


High dose rate (HDR) brachytherapy is a form of radiation treatment using temporary radioactive seeds. This is done by placing very tiny catheters or tubes into the prostate and then inserting temporary radioactive seeds, called Iridium 192, through these catheters. HDR brachytherapy gives precise radiation to the prostate with less radiation given to the normal tissues near the prostate. For patients who have been treated with external beam radiation to the prostate before, HDR brachytherapy can give radiation again to the prostate without exposing the normal tissues around the prostate to significantly more radiation. This may be safer than giving external beam radiation again. The purpose of this study is to test the safety of high dose rate temporary brachytherapy (HDR) for prostate cancer that has come back after external beam radiation. We want to find out what effects, good and/or bad, the treatment has on you and your recurrent prostate cancer.

Medical and Biotech [MESH] Definitions

Unstable isotopes of iridium that decay or disintegrate emitting radiation. Ir atoms with atomic weights 182-190, 192, and 194-198 are radioactive iridium isotopes.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

Radium. A radioactive element of the alkaline earth series of metals. It has the atomic symbol Ra, atomic number 88, and atomic weight 226. Radium is the product of the disintegration of uranium and is present in pitchblende and all ores containing uranium. It is used clinically as a source of beta and gamma-rays in radiotherapy, particularly BRACHYTHERAPY.

Mice selectively bred for hypersusceptibility to two-stage chemical skin carcinogenesis. They are also hypersusceptible to UV radiation tumorigenesis with single high-dose, but not chronic low-dose, exposures. SENCAR (SENsitive to CARcinogenesis) mice are used in research as an animal model for tumor production.

The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.
