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 …

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 …

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 …

A group of researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) reported in 2014 (see this link) on the outcomes of 42 patients with radio-recurrent prostate cancer treated with salvage high-dose-rate brachytherapy (sHDR-BT). The results were quite good — … READ MORE …

In several randomized clinical trials of external beam treatment of primary prostate cancer, we have seen that moderately hypofractionated intensity-modulated radiation therapy (HypoIMRT), accomplished in 12 to 26 treatments or fractions, is no worse than conventionally fractionated IMRT treatment (in 40 to 44 fractions). … READ MORE …

There has been some question as to whether the toxicity of delivering very high doses of external beam radiation per treatment (or fraction) in fewer fractions (called “extreme hypofractionation” or SBRT) would be high compared to conventional dose rates per fraction. … READ MORE …

In a recent commentary, we saw that the lack of a standard of care for stereotactic body radiation therapy (SBRT) dose escalation may put patients at risk when dose limits are pushed beyond what is customarily considered effective and safe. … READ MORE …
