A small, multi-center cohort study of SBRT in treatment of low-risk prostate cancer

Published reports on the safety and efficacy of extreme hypofactionated radiation therapy (stereotactic body radiation therapy or SBRT, a.k.a. CyberKnife radiation therapy) have, to date, come from just a couple of key centers. … READ MORE …

Registry initiative now holds data on > 500 CyberKnife patients

A multi-institutional “Registry for Prostate Cancer Radiosurgery” (RPCR) was initially set up in July 2010 to track clinical and functional outcomes of men with localized prostate cancer treated with the CyberKnife stereotactic body radiation therapy system (SBRT) at academic and community-based centers throughout the U.S. … READ MORE …

Dose escalation of SBRT in treatment of localized prostate cancer

Most published data on the use of stereotactic body radiation therapy (SBRT; CyberKnife radiation therapy) has been based on  a total radiation dose of 32 to 38 Gy delivered in a series of four or five sessions — as compared to the delivery of more like 75 to 80 Gy using intensity-modulated radiation (IMRT) and other forms of targeted external beam radiation therapy (EBRT). … READ MORE …

SBRT in treatment of isolated, prostate cancer-specific metastases to bone

Stereotactic body radiation therapy (SBRT), most commonly carried out using the CyberKnife “robotic radiosurgery” technology, is already being used as first-line treatment for men with low- and intermediate-risk, localized prostate cancer, but it can also be used for highly targeted radiation of boney metastases. … READ MORE …

4- and 5-year outcomes after SBRT for localized prostate cancer

Two posters presented today at the Genitourinary Cancers Symposium have extended our knowledge about outcomes after stereotactic body radiation therapy (SBRT or CyberKnife therapy) for localized disease. … READ MORE …

Outcomes following EBRT and an SBRT “boost” for localized prostate cancer

New data from the radiotherapy group at the University of Califronia, San Francisco suggests that stereotactic body radiation (SBRT) can be used to deliver a “boost” of focused radiation after external beam radiation therapy (EBRT). High dose rate (HDR) brachytherapy has also been used in this way in the past. … READ MORE …

Stereotactic body radiation: early data from a trial of CyberKnife therapy

The ‘New” Prostate Cancer InfoLink has previously stated the importance of having more data about the potential of CyberKnife therapy in the treatment of localized prostate cancer. The first such data are now available. … READ MORE …
