Multi-institutional data from the American Society of Therapeutic Radiation Oncology (ASTRO) consensus conference suggest that in patients treated for a rising PSA level, postoperative radiotherapy (typically in a dose range of 60-65 Gy) offers a PSA remission rate of 70%. Unfortunately, the durability of this response varies widely from center to center, with averages ranging from 25 to 67 months.
