Prostate-specific antigen kinetics following hypofractionated stereotactic body radiotherapy boost and whole pelvic radiotherapy for intermediate- and high-risk prostate cancer
Stereotactic body radiotherapy (SBRT) has emerged as an effective treatment for localized prostate cancer. However, prostate specific antigen (PSA) kinetics after SBRT has not been well characterized. The objective of the current study is to analyze the rate of PSA decline and PSA nadir following SBRT boost after whole pelvis radiotherapy (WPRT) in intermediate- and high-risk prostate cancer.
