Hypofractionation Is Ready for Prime Time in Prostate Cancer, but Will It Be Adopted?

“Separate phase III trials presented at the 2016 Genitourinary Cancers Symposium demonstrated that modest hypofractionated radiotherapy is noninferior to conventional radiotherapy for men with intermediate- and low-risk prostate cancer and should be considered a new standard of care.1,2 However, it is not clear how widely adopted hypofractionation schedules will be.

“NRG Oncology RTOG 0415 was a randomized, phase III, noninferiority study comparing two fractionation schedules in men with low-risk prostate cancer: conventional radiotherapy (73 Gy in 41 fractions over 8.3 weeks) vs hypofractionation (70 Gy in 28 fractions over 5.6 weeks).1

“The study enrolled 1,115 patients with low-risk prostate cancer. No androgen suppression was given. Patients were stratified according to Gleason score 2–4 and Gleason score 5–6.”
