Dick Smith - 17 Nov 2005 01:00 GMT I was just thinking today regarding men who have been diagnosed with aggressive PCa cancer. Has the notion been discussed regarding radiation directly after an RRP in these particular cases, instead of waiting to see if the PSA begins to climb? Has there been any studies done on this? My view is that if the cancer is still confined to the empty prostate bed, radiation would attack this localized cancer before it has a chance to escape.
gourd_dancer - 17 Nov 2005 02:22 GMT Dick, As one has has an aggresive strain, my thoughts are.......
Step out of the box or circle. Don't look at PCa as most Ca. Very rarely will one ever "see" tumors per se. Think of micro fibers floating through your blood system endlessly until they want to stop and feed; attaching themselves to some part of your body that needs blood supply. Think away from vessels and think at bone or soft-tissue.
After attaching, the micro fibers grows to where it can now be seen. Typically, seen when the damage starts to show.
The real problem is that once the micro fibers escape, it does not matter what your primary treatment was.... removal, internal radiation, or external radiation.... it is too late. You simply can not know or detect or that Ca lives somewhere in your body ready to start its life cycle.
When I started down this path, I was given a 92% shot of not having a micro fiber escape. I simply feel into the 8% group.

Has the notion been discussed regarding [quoted text clipped - 3 lines] > empty prostate bed, radiation would attack this localized cancer before > it has a chance to escape. Mine was a Gleason 8 with seminal vesicle involvement and a PSA velocity > 2.0 (which increases by a thousand percent my odds of dying OF PCa, according to a recent study). My oncs recommended ADT immediately following my RRP, because ADT fights PCa body-wide rather than just in the prostate bed and has the greatest chances of success when the target cell population is at its smallest. They didn't bring up the topic of adjuvant RT until we began discussing what to do if and when my cancer returns, apparently favoring RT after some significant time has gone by (my RRP was a year ago).
I'll start researching RT a whole lot further when my PSA starts up again, but I've already done enough research on it to know I wouldn't take it just because a doctor recommends it. Like the other treatments, it has its own suite and likelihood of SEs., and I want to evaluate them under the light of my own suite of priorities.

This is at least the second time you have referred to that study and I get the feeling it was posted here. If so, I missed it in one of my 100+ message review sessions. Can you repost it?
As you know, mine was a Gleason 7 with seminal vesicle involvement and a PSA of 16 (which had to incur significant doubling since it was below 4.0 two years prior).

I could dig it up from the literature and/or the archives, but it's been posted and discussed often by several people, and was only one lone study at the time, so it's not worth the effort. Probably of more validity regarding the implications of PSAV is the more recent, larger study posted here this week on PSA kinetics.

Steve Kramer - 17 Nov 2005 11:20 GMT It has been discussed. Has been tried and been reported on. It is more successful regarding percentages, but the percentages were inconclusive as to warrant putting men through all the RT SEs. Most docs are (and I think should be) discriminating.

Has the notion been discussed regarding [quoted text clipped - 3 lines] > empty prostate bed, radiation would attack this localized cancer before > it has a chance to escape. I have read that some doctors do advocate scheduling RT after RP without waiting for PSA to climb. However I believe that even they want to wait for the surgical wounds to heal before radiation so as not to impose crippling damage on the patient.
It seems to me that there are several separate aspects to your question.
1. Is RT necessary?
Even though the cancer was aggressive, what if the surgery got all of it? If it did, then enduring the radiation would be entirely unnecessary. If we don't wait for PSA to rise, we don't know if we actually needed radiation and we'd risk accepting all of the side effects of RT for no benefit.
2. Is RT more effective if given right away, without waiting for PSA to rise?
This is a tough one. We do know that RT is more effective earlier than later. We do know that the chances for metastasis increase with time. But we also know that tumor growth is generally accompanied by a rise in PSA. So the question is, is a rise in PSA a "leading" or "trailing" indicator of cancer progression that might not be treatable by RT?
If it's a leading indicator, then we can wait for a rise in PSA before radiating. If it's a trailing indicator, then when the PSA rises, it's too late.
It seems to me that the answer to that question is not known with certainty. We do know of men on this newsgroup and reported in studies who have had RP, had a rise in PSA, had RT, and the PSA rise stopped. So, at least for some men, a rise in PSA signalled a cancer progression that could still be stopped by RT.
However we also know that there are some men in the newsgroup who had a fairly small rise in PSA, got radiation, and did not see their cancer progression halted.
But even for those guys, we still don't know if RT before the rise in PSA would have helped them. It's entirely possible that if they had gotten RP and RT on the same day, they still wouldn't have gotten all the cancer because some had already established itself outside the treatable zone, or because some was somehow radiation resistant.
So I'm thinking that the answer to your question is that the desirability of RT post RP but before a rise in PSA probably differs for different specific cases, and nobody has a sure way to tell if it will help.
The solution that most doctors seem to adopt - wait for a rise in PSA before prescribing RT - seems reasonable in light of all the unknowns. However, if the pre-RP diagnosis was of an aggressive cancer, I would think an aggressive PSA testing schedule is desirable to catch any rise in PSA as early as possible.

Thank you for that well-stated voice of reason, which I am glad to see is starting to infuse the medical system. Even though the same rationale applies to early adjuvant ADT (to a lesser degree because ADT SEs are USUALLY and MOSTLY reversible), many people here have criticized delaying adjuvant ADT until biochemical or clinical failure.
I.P.
Alan Meyer - 17 Nov 2005 22:34 GMT > > 1. Is RT necessary? > > [quoted text clipped - 11 lines] > > I.P. In the case of ADT, the argument for waiting may be even stronger. With salvage radiation, it might be argued that the chance for a cure is reduced the longer we allow the cancer to grow. So waiting poses some possible risk. But if it's true that ADT cannot cure, then delaying to find out if it's really needed poses very little risk.
In my case, after radiation I had a PSA that went to .8, down to .6, then to .9, .8, and then 1.8. The 1.8 was pretty scary. My doctor advised waiting for ADT on the grounds that this might not be a recurrence even if it looks like one. My next PSA after that was .5. If I hadn't waited I'd be on ADT now, waiting for PSA failure and wondering how many injections to get before trying a breather.
I'm now resolved that I'm not going to go back on ADT unless and until I have incontrovertible evidence of recurrence.

My oncs hope that ADT has the greatest chance of helping the most if begun immediately while our immune system has the best chance of handling any small hormone-resistant component. ADT helps starve susceptible cancer cells on a proportional basis; i.e., each ADT round kills x% of existing cancer cells. If begun while the absolute cancer cell count is sufficiently low, the consensus hope is that the immune system can manage the survivors of an early assault. But waiting months may let the increased cancer cell count, even after ADT, overwhelm the immune system. That's probably why the same onc team who recommended early adjuvant ADT as soon as my surgery healed a year ago now suggest RT if adjuvant tx becomes advisable: the low absolute cancer cell count advantage has been lost.
But I'm not accepting RT even with a rising PSA unless exhaustive tests fail to find ANY indication it has spread beyond the reach of RT. Frying my "crotchal region" is pointless if there are lung or elbow mets; I'm crotchety enough as it is.
> If I hadn't waited I'd be on > ADT now, waiting for PSA failure and wondering how many > injections to get before trying a breather. As of 10 months ago, nothing under 28 months on ADT has shown to be effective, but the next lower step was 9 months -- a BIG gap. I vaguely recall new data a few months ago, but forget whether it reinforced or slightly shortened that number.
> I'm now resolved that I'm not going to go back on ADT unless > and until I have incontrovertible evidence of recurrence. While I agree personally, I'd never recommend others make that choice without exhaustive research . . . although the concurrence of Walsh and several of his peers sure helps.

BACKGROUND: Local failure after prostatectomy can arise in patients with cancer extending beyond the capsule. We did a randomised controlled trial to compare radical prostatectomy followed by immediate external irradiation with prostatectomy alone for patients with positive surgical margin or pT3 prostate cancer. METHODS: After undergoing radical retropubic prostatectomy, 503 patients were randomly assigned to a wait-and-see policy, and 502 to immediate postoperative radiotherapy (60 Gy conventional irradiation delivered over 6 weeks). Eligible patients had pN0M0 tumours and one or more pathological risk factors: capsule perforation, positive surgical margins, invasion of seminal vesicles. Our revised primary endpoint was biochemical progression-free survival. Analysis was by intention to treat. FINDINGS: The median age was 65 years (IQR 61-69). After a median follow-up of 5 years, biochemical progression-free survival was significantly improved in the irradiated group (74.0%, 98% CI 68.7-79.3 vs 52.6%, 46.6-58.5; p<0.0001). Clinical progression-free survival was also significantly improved (p=0.0009). The cumulative rate of locoregional failure was significantly lower in the irradiated group (p<0.0001). Grade 2 or 3 late effects were significantly more frequent in the postoperative irradiation group (p=0.0005), but severe toxic toxicity (grade 3 or higher) were rare, with a 5-year rate of 2.6% in the wait-and-see group and 4.2% in the postoperative irradiation group (p=0.0726). INTERPRETATION: Immediate external irradiation after radical prostatectomy improves biochemical progression-free survival and local control in patients with positive surgical margins or pT3 prostate cancer who are at high risk of progression. Further follow-up is needed to assess the effect on overall survival.

I. P. Freely - 17 Nov 2005 18:28 GMT > I was started on No, there's no accidental truncation there. That's the entire phrase pertinent to my point: We should regard PC treatment as OUR informed, asserted choice, not "the system's" mandate. "They" may do the cutting or frying or drugging or watching, but it should be WE who instigate the procedure, with their advice. Whether Roy's treatment was successful or was totally his informed choice is not important to the point; what IS important is that the potential effects, both intended and side, are far too complex and personal for us to trust even a team of oncologists, let alone any one physician, to dictate a treatment without very extensive and intensive and unbiased analysis of the pt's most personal mental and physical states and priorities . . . and that would be very rare and probably STILL inadequate.
That said, I hope Ray was involved and/or gets great results.

I don't think I've ever seen that before. The pathologist says you've got more Gleason 3 and more Gleason 5 than Gleason 4. It's as if the type 3 cells jump right to type 5.
Hmmmm.
I wonder if 3+5 is better than 4+4. I bet it is since the predominant cell type is 3.

Good question. I'd imagine the answer lies somewhere at the dirty margins. If all the G 5 was in the prostate, he's dealing with nothing but 3 now.

I figure we need to be prepared for the worst, but we shouldn't give up either on living or on fighting our disease.
Keep fighting, and best of luck to you.
