放射治疗是前列腺癌的主要治疗手段之一,既往多项临床研究表明,前列腺癌的局控率与放疗剂量成正相关[1,2]。近年来,随着三维适形放疗(three dimensional conformal radiation therapy,3D-CRT)和调强放疗(intensity modulated radiation therapy,IMRT)技术的应用,在正常组织受到较好的保护的情况下,靶区的照射剂量也能得到有效的提高。但是,这些精确放疗的实施

Radiation therapy is one of the main treatment of prostate cancer, past a number of clinical studies have shown that the control rate of prostate cancer and radiation dose is positively correlated [1,2]. In recent years, with the application of three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT), in the case of normal tissue being well protected, the target area The radiation dose can be effectively improved. However, the implementation of these precise radiotherapy
