Ending in October, 2004, I underwent salvage IMRT (Intensity Modulated Radiation Therapy) after failed cryosurgery. As the question pertains to salvage radiation, I believe that I have something to contribute.
IMRT is the latest "external beam" radiation therapy. It utilizes multiple beams of radiation which originate at various positions around the patient's body. A "gantry" moves around the patient and metal leaves can be heard moving about to preset positions, which is the shaping of the radiation beams.
It is guided in the following two manners:
(1) Pretreatment "simulation" during which x-rays are made in order to document the organ positions. It will involve a Foley catheter, which is used briefly to inject radio-opaque dye into the bladder. Also, a mold of the patient's lower extremities is made. This is used during the tx sessions to immobilize the patient (this is very important). The data obtained are used to preset the mode of tx as to position, shape, time, dosage, etc.
(2) Before each tx session (which is five days per week for ~seven weeks) the position of the organs is determined with ultrasound. It is called beta-Mode Acquisition and Targeting (BAT), and adjustments are made based upon its findings. This helps to assure that the radiation goes where it is desired.
As a matter of fact, in my case it was thought prudent to treat the seminal vesicles and pelvic lymph nodes at the same time. IOW, more than one organ can be treated during each session.
The sessions under the machine are perhaps10 minutes. There is no sensation. I wasn't even bored; I could see a computer monitor which showed the beam shape, time, dosage per cycle, etc. Fascinating.
SE's are different for each of us. In my case, I had mild diarrhea and urinary difficulty, the latter being treated with Flomax. I was also rather tired. Lost a bit of hair in the groin, which has returned. All in all, I would characterize it as a piece of cake. Such SE's as there may be usually begin after the second or third week.
*NB* I also began a regimen of ADT, using Zoladex, then Lupron, then Trelstar, which continues to the present. The reason for the changes was economic, except in the case of stopping Zoladex. That reason was simply pain of the injection into the lower abdomen.
The rad onc might very well prescribe neoadjuvant (pre-tx) as well as concurrent and post-tx ADT.
Of course, my story is just that: a story; anecdotal. Authoritative and objective information can be found on the website of the Prostate Cancer Research Institute at: http://prostate-cancer.org/index.html
Also: a google search on IMRT will result in a host of hits.
Best of luck. Please let us know what's next.

I have Lymphedema in both ankles and feet from "overspray" of 3D Conformal EBRT, simply because I have a fat a.s, had to have an increased dosage to do the distance, and they push you through like sheep in a dip! Additionally, the Prostate can move +- 7mm from the setup markers on any given day.
The IMRT sounds a little more accurate and is offered to me as an option if I need it down the track. (It is not a first choice option due to the extra time it takes, ergo the daily quota does not return the required dividends to justify the larger Cash outlay.)

Gordy - 06 Jul 2005 01:32 GMT I am just starting RT at Morristown (NJ) Mem. Hosp. Their machine, developed by head of the department, Dr. Wong, and Siemens, has a CT scanner attached. For the first 5 sessions, and periodically thereafter, they do a CT scan before the treatment. They are thus able to determine how much, and which way, the prostate of any particular patient, moves. The beauty of this machine is that the patient doesn't have to move between scan and treatment. I'm doing my "dry run" tomorrow and start actual treatments on Thursday.

I'd like to ask...would that be because some cancer cells 'leaked' out of the prostate?
I assume so but how do they live in those areas? (ear, toe?)
Thanks.

Leonard Evens - 06 Jul 2005 15:24 GMT > I.P. wrote: > [quoted text clipped - 3 lines] > I'd like to ask...would that be because some cancer cells 'leaked' out > of the prostate? There is nothing certain about any of this, but generally physicians believe that it is the nature of the cancer cells rather than whether they have escaped from the original site that determines if they can take up residence remotely. Originally, cancer cells resemble those in the tissue they formed in and they can only survive in that location. Later they may develop metastatic capability, meaning that they can survive elsewhere. It is presumed that cancer cells escape all the time but it is only after metastatic capability develops that you have a problem.
Treatment for the original prostate cancer, either surgically or by radiation, may not get all the cancer cells in the local area. After surgery, in that case, further radiation may destroy all the remaining cancer before it develops metastatic capability. But if some cancer cells with that capability already took up residence elsewhere in the body, then followup radiation won't do any good. The problem is that there is no way to be sure in case of recurrence whether or not the cancer is still localized. Physicians rely on certain statistical guidelines developed through studying many cases. If the recurrence time an doubling time for PSA are short, it is much more likely that the cancer has spread to distant sites and become metastatic. If the recurrence time and doubling times are longer, it is more likely that the recurrence is purely local. But even if the probability is hiigh, it is not certain. And there will always be marginal cases where the odds are about even. So the physician has to use everything he or she knows about the specific patient to help the patient decide on the proper course.
> I assume so but how do they live in those areas? (ear, toe?) In principle cancer can spread anywhere, but there are areas it is much more likely to appear in. for prostate cancer, bone is the most likely place for metastatic prostate cancer to appear in.

There are some tests that can help determine if the relapse is local or metastatic. They aren't perfect, but they give an indication. If they are negative, then it makes a lot of sense to get the radiation. If they are positive, then it may still make sense to get the radiation, but the decision is more difficult and the odds of success are reduced. Two tests that I'm thinking of are the alkaline phosphatase blood test (ALP), and the bone scan.
ALP is simple and cheap.
My recommendation to Arthur is to see a radiation oncologist ASAP, ask about whether an ALP and/or bone scan have been or should be done, and schedule the treatment.
I would go ahead and schedule the treatment even before the results of the test are in if, as is often the case, it takes 30 days or so to get into the schedule. There will be time to cancel the treatment if it turns out that the evidence of metastasis is strong.
I would also like to say to Arthur: The outcome on your surgery was bad but don't give up hope. There is still a decent chance that you will live out your life without dying of prostate cancer.
The radiation may very well cure you. Even if the cancer has spread outside the prostate itself. It usually spreads first into the first millimeter or so outside - where the radiation will hit it.
If that doesn't save you, then the natural progression of the disease is slow, and hormone therapy can slow it still further. New treatments are in trials now that have hope of saving you if and when the cancer becomes more widespread.
Best of luck.

Clarence Crow - 07 Jul 2005 00:47 GMT >My point was that the cancer producing the PSA relapse could be in an >earlobe or a toe rather than the crotch. > >I.P. Odd you should mention that. I have a bad 2L toe that will not entirely heal from over snipping the horny nail on it, April 24, near the end of my EBRT (I've had 3 courses of anti-biotics, one diagnosis of Cellulitis, plus a later diagnosis of Lymphedema, which was deemed to be attributable to overspray from the EBRT. Even had a Doppler U/Sound on the toe leg to see if there was a clot (negative).
Perhaps it's a distant Met??? Sure hurts in the cold spell we have here right now ;p

Bill - 06 Jul 2005 15:01 GMT Arthur, the no. 1 question now is whether you have a local recurrence or is it systemic because RT will cure the former but not the latter. You cannot know for sure so you need to confer w/ your docs, study the stats, and decide where you stand. At almost 72 you need to evaluate your general health and life expectatancy - if you probably won't live 10 years anyway, you might seriously consider doing nothing right now. Keep in mind that the rad-onc makes his living treating people so he is likely to favor having RT regardless. As for IMRT vs. standard RT I can only say that the rad-onc I saw at M.D. Anderson 4/04 told me that IMRT was not necessary for salvage treatment.
I am having blood drawn for a PSA today and I suspect I'll go from .45 to over .6 but I have pretty much decided not to have salvage RT due to seminal vesicle involvement. That and that I am losing my insurance and would have to pay the $40-60,000 out of pocket.

I also was told by two different rad-oncs that IMRT confers no special advantages in many cases. In salvage therapy, I think they're aiming at a relatively larger area anyway than initial treatment.

I thought it was illegal for insurance companies to cut you off because of changes in your medical condition or even because you have lost a job that paid for it.
Is it possible that you could find a counselor somewhere who knows the laws on this and can advise you of a way to keep your insurance?

Bill - 07 Jul 2005 15:23 GMT Alan, when I left a co. group plan in 1999 and after COBRA ran out I was shopping for private ins. I was working w/ a broker and was told I would have no problem w/ acceptance (pre-PCa). Based on that I let my HIPPA rights expire. I was promptly turned down due to a form of arthritis that is considered an auto-immune disease but is nothing but a cheap irritation to me. Once you are turned down for medical reasons you are essentially black-listed. My only option was Tennessee's version of Medicaid, TennCare, which covered uninsurables. It was not free - I paid as much as $550/mo. for 1 person. TennCare was far too ambitious and generous and was about to bankrupt the State so they are dropping all those who do not qualify for Medicare. It is a fiasco but I am lucky because I can afford my care while many cannot.
Does anyone know of any private ins. that will cover folks like us? I am willing to even exclude PCa and arthritis - I need something in case I trip and fall on my butt walking out to get the mail!
When I was in yesterday just to get PSA blood drawn, my uro popped into the room and decided he'd give me a DRE. Nice of him, huh? He felt nothing, which supports my decision so far to not have salvage RT because I assume I am metastatic.
Re Arthur's having a bone scan - w/ PSA of .7 it more than likely will show nothing even if there are mets - the test is just not that sensitive. Same w/ ProstaScint. But they will probably want to do them anyway.

I'm interested in this too. I'm at seeding + 9 months and the 3rd post treatment PSA came in at 0.4. The first two were < 0.1's and were taken while I was juiced with Lupron. This is a month after the rad-doc cautioned me to expect a "bounce".
The 0.4 is also 4 months after the declined 3rd Lupron shot.
The uro-doc says that he's not "worried" but that we need to track the PSA. He said if it doubles from here, he'd be concerned.
The insurance issue is that I'm considering bailing out from a bad employment situation. I have a friend who I've worked for before who has some decent rate contract work but, no benefits.
I can Cobra my current gold-plated insurance which covered fifty thousand dollars of cancer treatment last year. Beyond that, what are the issues?
The two <0.1 PSA's may have given me a false sense of confidence.
I can always get a job with benefits but don't know if the insurers are compelled to cover pre-existing cancer.
What's the story on insurance?
-- Update --
Other than the 0.4 PSA, things are going well. The fatigue is fading. The erections are returning, I don't have quite the libido that I used to but I find myself oogling women.
I can drink 32 ounces of water and sleep for 8 hours. When I go, the stream is strong. It does "sting". I dropped the Flomax at 6 months and don't take the Aleve either. The rad-doc prescribed Flomax in the morning and an Aleve at night.
I had a "diabetes" scare while on the Lupron. I clocked a 300 fasting blood sugar. This was on a high carb, multiple regular Pepsi's/day diet.
My primary care doc put me on 850 mg glucophage. I cut way back on carbs. I was seeing fasting blood sugars in the 150-200 range. This was just after the declined Lupron shot.
A couple months ago, the doc doubled the dose of Glucophage.
For the last 2 months, I've been clocking fasting blood sugars in the 110-130 range. It's consistant so I'm cutting the dose back to one 850 a day to see what happens. I've also added a small amount of carbs back to my diet, as in 2 slices of rye bread, with a meal.
If I can't hold 110-130, I'll drop the carbs before I add the 2nd 850 Glucophage back. I consider the meds a last resort.
If the problem was the Lupron, I'll be able to tell by tuning my diet and the Glucophage.
We'll see.

My results were:
<.2, <.2, .8, .6, .9, .8 1.8, .5
When I saw the 1.8 I thought I was a goner. But then it came down to .5.
Apparently PSA bounces like this are very common for men with brachytherapy. I have considerable hope that my treatment worked, and I think there is an excellent chance that yours worked too.
PSA doesn't fall all at once after brachytherapy, and the Lupron you had made your first couple of tests invalid.

Steve Kramer - 09 Jul 2005 20:12 GMT Hi, Art. Welcome to the club. Sorry for the relapse. My relapse came about 1½ years after RRP. I did 35 treatments of EBRT between May and July 2002.
With the possible side effects explained to me, I began to prepare about March. Most notably, I walked more (3-5 miles a day, 2-5 days a week) and drank more water.
As briefly as possible, one week before beginning, they put me on a table and scanned me to find exactly where my organs were, at which time they "tattooed" my midsection with small Xs. These Xs were later to serve as precise pointers for the "radiation machine".
On a Monday in May, they led me to another table that had a particle accelerated built around it. I took off tie, suit coat and pants, and shoes and laid on the table. The particle accelerated was guided around me and shot particles through me at six separate points. I felt nothing.
I did this 35 straight business days, finishing July 3, 2002.
Beginning on the first date, I went to bed one hour earlier and continued my walking and drinking water throughout.
Due, I think, to my preparation, my side effects were minimal. My wife said I was fatigued, thought I did not notice. I noticed slight looseness in the bowels, so I ceased the Metamucil I had started a couple years earlier. I had slight burning during urination towards the end of the treatment.
 Signature PSA 16 10/17/2000 @ 46 Biopsy 11/01/2000 G7 (3+4), T2c RRP 12/15/2000 G7 (3+4), T3cN0M0 Neg margins PSA .1 .1 .1 .27 .37 .75 EBRT 05-07/2002 @ 47 PSA .34 .22 .15 .21 .32 Lupron 07/03 (1 mo) 8/03 (4 mo), 12/03, 4/04, 09/04, 01/05 PSA .07 .05 .06 .05 non Illegitimi carborundum

Metamucil works both ways, driving stool consistency from either extreme towards normal. I use it to firm up my stool now that I've donated half my colon to the beast and water extraction isn't what it should be.

I don't know the details of Steve's case, but I thought that, statistically, most people with very low PSA values such as his do not (yet) have metastatic cancer.
I have read that when cancer first escapes from the prostate it penetrates just a few millimeters into the surrounding tissue, i.e., the famous "positive margins". It can still take a long time before it becomes metastatic.
If I were in Steve's shoes, I would go for salvage radiation unless there was positive evidence of metastasis. The absence of evidence for localized cancer wouldn't be enough to convince me not to get the radiation (unless of course I were a lot older than Steve and expected to die before the cancer got me.)
