(125I or 103Pd seeds) to treat selected localized prostate cancer patients has been rapidly increasing all over the world in the last fifteen years.To date, it is estimated that more than 50,000 patients are treated this way every year in the world, and this number is ...
This procedure, called brachytherapy, involves making an incision under general anesthesia to implant pellets into the prostate gland that release low doses of radiation slowly over a period of months. About 40 to 150 rice-size seeds are implanted, and they lose their radioactivity over the course...
"The precise control over dose delivery inherent in HDR brachytherapy is not readily achievable with low-dose rate (LDR) brachytherapy because of several factors: movement of the radioactive seeds away from the target site, swelling of the prostate after the implant and uncertain dose delivery out...
Radiation therapy is used to treat many types of cancer, including cancer of the lung, breast, prostate, testicles, and brain.When a tumor is going to be removed surgically, radiation can shrink it. This reduces the amount of normal tissue that needs to be removed near the tumor. When ...

‘seeds’ or pellets into the body near the tumor and leaves them for a time so that the seeds will irradiate the cancer cells. For breast cancer, the radioactive pellets are planted under the chest or just below the underarms. Since they must be inserted and removed several times through...
This process is still experimental, but because it can be used to selectively attack only cancer cells, it holds promise for eliminating cancers that have spread beyond the primary tumor. Radiation used to treat cancer PHOTON RADIATION. Early radiation therapy used x rays like those used to take...
High-Dose Rate (HDR) Brachytherapyis a radiation treatment that is delivered via radioactive “seeds” that are placed directly in or near the tumor. HDR allows doctors to use a higher total dose of radiation to treat a smaller area in less time than conventional external beam radiation therap...
There are several trials aimed at improving the implantation technique, including the FAST trial which has studied texture-coated iodine-125 (I-125) seeds to limit post-implant displacement and migration (NCT01174017) and the J0511 trial investigating robot-guided radioactive seed implantation (NCT...
The hand dose was ~0.5 mSv/procedure in this study, which is roughly equivalent to other results for doses received by brachytherapy physicians, such as when using 125I seeds for prostate cancer [71,72]. According to our assessment, 198Au brachytherapy physicians are unlikely to exceed the re...
