Hypofractionated high-dose intensity-modulated radiotherapy

From Wikipedia, the free encyclopedia

This is an experimental form of intensity-modulated radiotherapy where higher X-ray dosages are used in fewer fractions (sessions) this is called hypofractionated radiotherapy. Although the dose per fraction is higher than standard radiotherapy, the total dose is lower.[1]

The hope is that it will be as effective but cause less toxicity.[1]

Prostate cancer

[edit]

One trial[2] for prostate cancer ran in 2011.[1] In 2016 the HYPRO study reported results comparing the use of standard fractionation (39 fractions of 2 Gy for 8 weeks) with hypofractionation (with 19 fractions of 3.4 Gy for 6.5 weeks) among 820 patients with intermediate- or high-risk prostate cancer.[3]
