FOR NEWLY DIAGNOSED MEN
1. Before choosing a therapy it is critical to understand one's risk stratification; the clues to which are in your clinical diagnosis medical record. My favorite tool is the CAPRA score
www.prostate-cancer.org/pcricms/sites/default/files/PDFs/Is13-4_p3-7.pdf2. A good step-by-step process for evaluating options for men newly diagnosed is here
www.prostate-cancer.org/pcricms/node/1263. Many technology improvements to brachytherapy and external beam radiation have greatly improved the long term PSA control in recent years. It now appears brachy has the best long term PSA control and lowest side effects risk. Men at high risk may use brachy to get maximum dose inside the prostate, and Image Guided IMRT External Beam radiation to mop up any cancer just outside the prostate or seminal vesicles, or adjacent lymph nodes. See the reports by Doctor Peter Grimm and Dr. Pat Kupelian in the May issue of PCRI Insights, available here in a couple weeks.

www.prostate-cancer.org/education/staging/bonescan.htmlBut, the latest multi-parametric MRI techniques can detect more than 80% of tumors of about
a centimeter or larger. MRI can also find tumors at the top, bottom, and front of the prostate that usually cannot be detected with DRE or trans-rectal biopsy. That might change a man's treatment choice. Read several papers about
MRI here

PROTON Radiation -- In the 1990s when Loma Linda started doing Proton Beam radiation of prostates, it was clearly superior to the external beam technology at the time. That has changed. Modern Image Guided IMRT can achieve equally high dose and control, while modern brachytherapy can achieve much higher dose inside the prostate. I am not aware of any large scale clinical reports that prove proton beam is better than the latest technology IMRT.
