摘要: High-dose-rate (HDR) brachytherapy as monotherapy for prostate cancer has theoretical advantages in both aspects of radiation physics and biology compared to other radiotherapy modalities. The three-dimensional four-dimensional dose distribution HDR is superb, maximizes the biological escalation. In former part this chapter, techniques implant treatment planning are mentioned, followed by it’s advantages. latter half, clinical evidence overviewed along with its history over 20 years. Since dawning four- nine-fraction regimens, been moving on more hypofractionated regimens. latest two- or single-fraction vigorously discussed.
