In contrast to low-dose-rate (LDR) brachytherapy, where radioactive seed implants are placed permanently in the body and gradually deposit low levels of radiation over a period of months, HDR ...

Brachytherapy involves the use of radiation to damage the DNA of cancer cells and destruct its ability to grow. A recent clinical trial found high-dose-rate of brachytherapy 19 Gray (Gy) treatment ...

PURPOSE: We performed a matched-pair analysis to compare our institution’s experience in treating locally advanced prostate cancer with external-beam radiation therapy (EBRT) alone to EBRT in ...

Brachytherapy is a type of cancer treatment, also called internal radiation therapy, that involves placing a sealed radioactive source in or near a tumor to destroy the cancer cells.

HDR brachytherapy also contrasts in another way with the tiny radiotherapeutic implants we wrote about earlier. Those implants deliver a low dose of radiation over a long period of time, where ...
