Hypofractionated Radiotherapy
Radiosurgery and conventional radiotherapy define two extremes in a continuum of potential fractionation schemes. Hypofractionated radiation therapy provides important potential advantages in cost and convenience for patients and these recommendations are intended to provide guidance on moderate hypofractionation and ultrahypofractionation for localized prostate cancer.

Hypofractionated radiotherapy. For selected patients with breast cancer considerable evidence from large randomised trials with long follow up primarily in the setting of breast conservation supports the equivalent efficacy and toxicity of shorter courses of hypofractionated whole breast. The rationale for the various hypofractionated regimens is based on mathematical. 138 women received hypofractionated whole breast radiation 4256 gray over a period of 3 weeks plus a boost dose the women were all 40 years of age or older and 76 217 women were overweight or obese.
Hypofractionated radiation therapy is given over a shorter period of time fewer days or weeks than standard radiation therapy. Apart from the therapeutic rationale there. Radiation treatment in which the total dose of radiation is divided into large doses and treatments are given once a day or less often.
The women on the hypofractionated radiation schedule had fewer side effects than the women on the conventional radiation schedule. Hypofractionation is an elegant approach that promises to help to contain the costs of cancer care and mitigate financial toxicity. Hypofractionated radiotherapy is given over a shorter period of time than standard radiation therapy.
Using hypofractionation or hypofractionated radiation therapy more doses of radiation are delivered per treatment so patients can complete their course of radiation therapy much faster than conventional treatment and costs patients less money. Previous studies have reported encouraging survival results and favorable toxicity with fractionated stereotactic radiotherapy and small studies have shown similar benefit using a shortened course of hypofractionated stereotactic radiation therapy h srt. For this radiation treatment the total dose of radiation is divided into large doses and treatments are given once a day or less often.
This continuum where doses 20 gy are administered over 25 sessions are termed hypofractionated radiotherapy. Hypofractionated radiotherapy is increasingly being used to treat cancer. Original article from the new england journal of medicine long term results of hypofractionated radiation therapy for breast cancer.
In the last few years hypofractionated external beam radiotherapy has gained increasing popularity for prostate cancer treatment since sufficient evidence exists that prostate cancer has a low ab ratio lower than the one of the surrounding organs at risk and thus there is a potential therapeutic benefit of using larger fractionated single doses.
