Should SBRT be THE preferred treatment for intermediate-risk prostate cancer?

Last year, the American Society of Radiation Oncologists (ASTRO) looked at the available evidence comparing hypofractionated radiotherapy (either 60 Gy in 20 treatments or 70 Gy in 28 treatments) to standard fractionation (78 to 82 Gy in 40 to 44 treatments), and found it was at least as good in terms of oncological outcomes and toxicity. … READ MORE …

SBRT has non-inferior acute and late-term toxicity vs IMRT in two randomized clinical trials

In October 2018, the American Society of Radiation Oncologists (ASTRO) strongly endorsed moderately hypofractionated IMRT (20 or 28 treatments) for primary radiation treatment (see this link). … READ MORE …

SBRT: the optimal dose

While excellent outcomes of stereotactic body radiation therapy (SBRT) have been reported since it was first used to treat prostate cancer in 2003, the delivered doses have ranged from 35 Gy in five treatments to 40 Gy in five treatments. … READ MORE …

SBRT has excellent outcomes for intermediate-risk patients

Stereotactic body radiation therapy or SBRT (sometimes referred to as SABR or SHARP or CyberKnife) has had excellent 7-year outcomes in an update of the consortium study, including data from 10 single-institution trials and two multi-institutional trials. … READ MORE …

Updated results of 5-year SBRT trial: high cancer control, low toxicity

Meier et al. have just published updated results of a 5-year multi-institutional trial finding that stereotactic body radiation therapy (SBRT) had high rates of cancer control and low toxicity. … READ MORE …

SBRT has equivalent toxicity with 5 treatments and 12 treatments: an update

We first reported data from the results of the RTOG 0938 trial in January 2016 when they were presented at the Genitourinary Cancers Symposium in that year. These results have now been formally published, and there are some changes to the data on publication, so Allen Edel has provided an update. … READ MORE …

First randomized clinical trial of SBRT reports primary outcome

In the first trial ever to randomly assign patients to extreme hypofractionation, primary radiation therapy delivered in just seven treatments had the same effectiveness and safety as 39 treatments. … READ MORE …
