NCT03322020

Brief Summary

For the treatment for intermediate- and high-risk prostate cancer, Cyberknife boost will be used after 4 weeks of intensity modulated radiotherapy to pelvis. The boost doses are 18 Gy and 21 Gy in 3 fractions, respectively. The investigators plan to evaluate the toxicity of two dose groups and decide the appropriate dose for Cyberknife boost. Also, PSA control will be evaluated.
