TL;DR: The hypofractionated RT regimen used in this trial was not inferior to conventional RT and was not associated with increased late toxicity, and should be considered for intermediate-risk prostate cancer.
Journal ArticleDOI

TL;DR: In men with low-risk prostate cancer, the efficacy of 70 Gy in 28 fractions over 5.6 weeks is not inferior to 73.8 Gy in 41 fractions over 8.2 weeks, although an increase in late GI/genitourinary adverse events was observed in patients treated with H-RT.
Journal ArticleDOI
Randomized trial comparing iridium implant plus external-beam radiation therapy with external-beam radiation therapy alone in node-negative locally advanced cancer of the prostate.
TL;DR: This trial provides evidence that higher doses of radiation delivered in a shorter duration result in better local as well as biochemical control in locally advanced prostrate cancer.
Journal ArticleDOI
Intensity-modulated fractionated radiotherapy versus stereotactic body radiotherapy for prostate cancer (PACE-B): acute toxicity findings from an international, randomised, open-label, phase 3, non-inferiority trial.

TL;DR: The results suggest that substantially shortening treatment courses with stereotactic body radiotherapy does not increase either gastrointestinal or genitourinary acute toxicity.
Journal ArticleDOI
External beam accelerated partial breast irradiation versus whole breast irradiation after breast conserving surgery in women with ductal carcinoma in situ and node-negative breast cancer (RAPID): a randomised controlled trial.

TL;DR: External beam APBI was non-inferior to whole breast irradiation in preventing ipsilateral breast tumour recurrence (IBTR), analysed by intention to treat and less acute toxicity was observed.
