Unwarranted conclusions about treatment of oligometastatic prostate cancer

Many patients wonder, if they just have a couple of metastases, why can’t those be “zapped” by a few quick SBRT treatments and they can’t thereby be cured of their prostate cancer? Or, even if they can’t be cured, can’t the cancer’s progression be slowed down? … READ MORE …

SBRT dose escalation

Is there an optimum treatment dose for sterotactic body radiation therapy (SBRT)? … READ MORE …

SBRT vs. standard IMRT as first-line radiation therapy for localized prostate cancer

Many readers may be interested in an article by Gina Kolata in today’s issue of The New York Times. It deals with the rising popularity of stereotactic body radiation therapy (SBRT) in the management of localized prostate cancer. … READ MORE …

Less treatment regret with SBRT, and when patients are fully informed

There is growing recognition that the patient’s satisfaction or regret with his treatment decision is more than just a matter of whether he is happy with the oncological outcome. Satisfaction/regret is the product of many variables, including how well he understood his options, his interactions with his doctors, the side effects he suffered and when he suffered them, his expectations about the side effects of treatment, and cultural factors. … READ MORE …

SBRT vs. moderate hypofractionation: same or better quality of life?

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 …

Toxicity equal for SBRT and conventional external beam radiation (3D-CRT)

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 …

5-Year SBRT trial: high cancer control, low toxicity

Data from a 5-year-long, multi-institutional trial, reported at the recent ASTRO meeting, showed that stereotactic body radiation therapy (SBRT) had high rates of cancer control and low toxicity. … READ MORE …
