still reading the postings, still learning from them

As I am only limited to beam radiation therapy because of previous TRUP operation I was wondering how important are the various guidance systems that are used as far as limiting damage to the rectum ? Also I have a cancer treatment centers of America that is opening soon near to my home. I havenít interviewed with them yet but they sound great. What is their reputation as regarding prostate cancer? Thank you all for sharing your knowledge you have ben a great help to me so far.

Re: still reading the postings, still learning from them

Image-Guided Radiation Therapy (IGRT) is important in avoiding side-effects of treatment and is especially important to you because of your previous TURP. There are two ways to do it. They can implant in your prostate little gold markers about the size of rice grains called fiducials. Or, they can implant small radio transponders (This is called Calypso). Either one works fine and enables them to track the position of your prostate between treatments - called inter-fractional motion. IGRT is often combined with IMRT in such systems as Tomotherapy and many others.

CyberKnife additionally tracks the motion of the prostate during each treatment - called intra-fractional motion. With CyberKnife, IGRT is combined with SBRT.

With proton therapy, they place a balloon in the rectum during each treatment. This holds the prostate in place so it doesn't move around too much.

The better they track the motion of your prostate, the more the radiation treats only the prostate and not the places you don't want the radiation to go, like the rectum, the bladder neck, the penile bulb and the pelvic bones. Even with the sub-millimeter accuracy of CyberKnife there will be some acute and possibly some late-term urinary and bowel irritative symptoms. Also, some men are more sensitive to the irritative side effects of radiation than others.

Re: still reading the postings, still learning from them

Hi rushemose,

I'm replying after reading Allen's response to you.

Regarding a new Cancer Treatment Centers of America, a key question is whether they would have doctors highly experienced and expert in prostate cancer, and the equipment, especially in the approach that you decide you want. It seems to me a bit unlikely that a highly experienced doctor would move to such a new facility, but it could happen. With any institution, we need to be alert for a strong sales pitch that stems from the institution's interests rather than ours. It's fine if they are offering from real strength in one or more approaches and are objective; it's not fine if they discourage us from other sound approaches where they are not strong.

Take care,

Jim
