juniper - 11 Apr 2006 03:04 GMT Hi, all. We met our local uro today. He is so cool. He was very open and information-gathering. He said he thought it was appropriate we were going at it very aggressively ("full court press") and that it looked like our onc knew what she was doing. He is fine with treating Steve and helping with ED issues. He says there's two trains of thought on the maintaining function, but he's fine with VitV (do mail programs kick out emails with that word?), that the shots are not an option during chemo, that we can try a VED if we want, half of people like it okay and half don't. He lent us a video, although Steve has already seen one from Tom B, I haven't yet. Since we are more interested in preserving potential function than trying to have intercourse, we're going to try it as an exercise device at least. Also a colonoscopy today showed nothing, one tiny polyp, dr will call after path report. No concerns at this point. Anyway, that's our update. A good local uro.
I asked him about RT with pos lymph nodes with my standard argument that we'd be asking for a bunch more SEs without probable benefit. He said he would question that, with known pos nodes, but that we should consult with Grado and that he thought Grado would recommend it. I said, "Yes, because that's what Grado does," and he nodded but didn't say anything.
I realize we need to consult with Grado, and am eager to do so, but really I would like more information about why this would be a good idea. Or not.
I can find studies of RT with and without ADT, but my question is the opposite of that. Are there any studies of ADT with and without radiation? That is my question, really. Will RT add any advantage to ADT+chemo? Also, I only found one thing about identifying nodal involvement and targeting it, rather than doing a blanket dose of radiation basically from the navel to the knees (exaggerating only slightly).
I can find a lot of information on clinically localized cancer and RT, but once we got the path report it trumped the "clinically localized" staging. And not much on salvage RT w/pos lymph nodes. This had a lot of stuff but I don't know how useful it was after all http://tinyurl.com/ldhds.
Some various quotes that indicate to me that there is no positive indications for this (remember, his prostate is gone) or else indicate RT after PSA has started rising but before it reaches .02:
... The optimal management of patients with lymph node-positive prostate cancer remains controversial. The role of pelvic irradiation in patients at high risk for nodal involvement continues to be debated. Studies of prostate irradiation with and without inclusion of the pelvic lymph nodes show poor outcomes for node-positive patients, supporting the concept that many of these patients have systemic disease at presentation. Although no randomized trial has examined the role of pelvic irradiation in pathologically node-positive patients, available data fail to reveal any significant benefit of this approach over prostate-alone irradiation. More promising therapeutic approaches involve the combination of local therapy and sustained hormonal therapy. Series comparing prophylactic irradiation of the pelvis and prostate to irradiation of the prostate alone have shown no clear benefit of pelvic irradiation. Pelvic irradiation may play a role in the treatment of early-stage or occult nodal disease, although this has yet to be examined. Until prospective, randomized trials demonstrate the efficacy of pelvic irradiation in the management of prostate cancer, its use cannot be routinely recommended. .... In patients with locally advanced prostate cancer, RT-PCR/hK2 (to detect lymph node pos) is strongly associated with prostate cancer progression, failure following salvage radiation therapy, development of clinically evident metastases, and prostate cancer-specific mortality after surgery. ... http://theoncologist.alphamedpress.org/cgi/reprint/6/2/183 (A grand rounds)
This one indicates to me that salvage RT should wait for PSADT, which I assume would happen after ADT: Salvage radiotherapy is an effective method for achieving PSA response and improving progression-free survival in post-RP patients with a rising PSA,[28,29] but is most useful in select patient populations. Two large retrospective studies found that patients with Gleason score 8-10, preradiotherapy PSA < 2.0 ng/mL, negative surgical margins, PSA doubling time </= 10 months, and seminal vesicle invasion independently predicted disease progression.[30,31] Nevertheless, early salvage radiotherapy (ie, upon detection of PSA </= 2.0 ng/mL) enabled patients with Gleason 8-10 and positive surgical margins to achieve a 4-year progression-free probability of 81% when the PSA doubling time was > 10 months and a 37% probability when the PSA doubling time was </= 10 months.[31] Thus, even for patients with other adverse features, patients with PSA doubling time > 10 months can show durable responses to early salvage radiotherapy, whereas those with PSA doubling time </= 10 months are more likely to show poorer response and should therefore be considered for more aggressive therapy.

BACKGROUND: Radiotherapy (RT) has been used with success after radical retropubic prostatectomy (RRP), both in the adjuvant and salvage settings. The purpose of the current investigation was to systematically compare adjuvant versus salvage RT in a manner that incorporates both treatment efficacy and complications. METHODS: A literature review was performed of reports of post-RRP salvage and adjuvant RT, and 12 trials comprising 1060 patients met the appropriate inclusion criteria. The biochemical failure-free survival in each study/arm was tabulated, and these values were entered into a model to compute an unadjusted number-needed-to treat (NNT). RT complications were then considered, accounting for differences in toxicity incidences in the salvage versus adjuvant setting, to compute complication-adjusted NNTs. In all the trials, the signs and magnitudes of the NNTs obtained were used to compare adjuvant with salvage RT. RESULTS: The absolute NNT analysis showed an advantage of adjuvant compared with salvage RT. After adjustment for RT complications, however, the advantage shifted to salvage RT. This transition point from superiority of adjuvant RT to superiority of salvage RT was sensitive to the estimated incidence and severity of RT side effects. CONCLUSIONS: Adjuvant post-RRP RT was advantageous in comparison to salvage RT if the side effects of RT were estimated to be negligible. However, with moderate incidence/severity of RT side effects, salvage RT was advantageous. The findings herein must be tested in a prospective study in which both health-related quality of life and cancer control are documented in patients receiving adjuvant versus salvage post-RRP RT. Further work is needed to better estimate parameters entered into the model to determine the precise transition point between adjuvant and salvage RT with modern RT techniques.

Patients with pathologic stage T3 or T4 prostate cancer who have undetectable PSA levels following radical retropubic prostatectomy (RRP) have a substantial risk of recurrence. Radiotherapy (RT) can be administered immediately following the RRP (immediate adjuvant RT) or may be postponed until the PSA level has risen to a level that is indicative of residual or recurrent prostate cancer (salvage RT). Immediate adjuvant RT can significantly reduce the risk of relapse, but does not appear to increase the rate of survival. Approximately two-thirds of patients with rising PSA levels after RRP can be salvaged with RT alone. This result was achieved in patients treated with an adequate dose of radiation before the PSA rose to > 1.1 ng/ml. While no one can be certain which approach (adjuvant or salvage RT) is better, future studies should examine this issue. Whether immediate postoperative adjuvant RT is of value to patients is the subject of two randomized prospective studies. The benefit of adjuvant RT is a matter of controversy. Salvage RT treats only those patients with proven residual prostate cancer. The salvage RT approach has several advantages. This approach spares approximately 40% of patients who have had an RRP for T3 or T4 prostate cancer and eliminates the risks and costs associated with adjuvant RT. Additionally, it appears that the results of immediate adjuvant RT are similar to those achieved with early salvage RT.

juniper - 11 Apr 2006 03:31 GMT Treatment of prostate cancer with regional lymph node (N1) metastasis.
Pollack A, Horwitz EM, Movsas B.
Department of Radiation Oncology, Fox Chase Cancer Center, Philadelphia, PA 19111, USA.
Prostate cancer with pathologically documented regional lymph node positive disease has been associated with a dismal prognosis in the past. Clinical and/or biochemical progression is evident within 5 years in over 50% treated with external-beam radiotherapy (EBRT) alone, radical prostatectomy (RP) alone, or androgen deprivation (AD) alone. By 10 years after treatment, greater than 75% progress and over half succumb to prostate cancer. In contrast, the results with the combination of EBRT + AD or RP + AD have been very promising. Ten-year biochemical progression and overall survival rates are roughly 20% and 70%, respectively, for patients with subclinical lymph node involvement. Patients with a 10-year life expectancy should be treated aggressively with long-term AD combined with either EBRT or RP. Copyright 2003 Elsevier Inc.

I think she may be referring to spambots cruising the newsgroups picking up on keywords, such as Vitamin V and Vitamin C--lis, etc. This may be so, as the volume of spam I now get pushing sales of these and other related items has dramatically increased over the time I've been on this newsgroup. I did mention some of these products by name in a couple of my posts, and although my email address at the time was munged, it may not have been done so sufficiently to prevent identification.

Most people are concerned > about RT because of the inability to know whether it is killing any cancer. The known cancer is at the bladder neck and in the lymph. I'm thinking that ADT and chemo together might get that anyway. So then what is the point of RT? Just the extra SEs? I wonder if they even use radiation for bladder neck cancer. Maybe they just cut it out and rebuild the bladder? Anyway, bye bye continence if they irridiate the bladder neck. How long ago did you have RT and what are your SEs? It was post-RP, wasn't it? Do you think it was worth it? Do you know where your remaining cancer is? Did you know anything about where your cancer *was* post-RP and pre-RT? You had neg margins, right? How did you decide what areas to irridiate? Were/are you concerned about future cancer being created (stimulated, whatever) by having RT?

One posibility as you made all these corrections is that at 4 weeks a circulating PSA as high as 26.0 ng/ml (and possibly increased by surgical spill) has not been completely metabolized in four weeks. PSA's clearing rate is biphasic and the first phase is fast, but the second phase is slower. Maybe a retest is in order here.

Allow me to quote from Dr. Leibowitz's web site at:
http://www.prostatepointers.org/leibowitz/DrLeib13.html
At this 1994 meeting, the results showed that hormone blockade plus radiation therapy arm is doing much better than radiation therapy alone.
I pointed out to the speaker during the ensuing question and answer session that their study had just shown hormone blockade works in prostate cancer. I also stated that the next study needs a hormone blockade only arm versus hormone blockade plus radiation since, in my opinion, the just completed study proved hormone blockade is necessary, but does not confirm any value of radiation. A comment after the session went something like this:
"Bob, do you really think a radiation therapy group is going to do a study that could prove radiation is useless treatment for prostate cancer?"

Zagars GK, Pollack A, von Eschenbach AC. Addition of radiation therapy to androgen ablation improves outcome for subclinically node-positive prostate cancer. Urology. 2001 Aug;58(2):233-9.
OBJECTIVES: To determine the outcome for node-positive prostate cancer treated by early androgen ablation with or without prostatic radiation. METHODS: Two hundred fifty-five men with lymphadenectomy-proven pelvic nodal metastases treated with early androgen ablation alone (n = 183) or with combined ablation and radiation (n = 72) between 1984 and 1998 were retrospectively reviewed for disease outcome and survival. Post-treatment disease status was based on the prostate-specific antigen levels or on the clinical and radiographic status for patients treated before 1987. Univariate and multivariate statistics were used to determine the prognostic factors and assess the influence of radiation treatment. RESULTS: With a median follow-up of 9.4 years, the 5, 10, and 13-year overall survival rate for those treated with early ablation alone was 83%, 46%, and 21%, respectively. The freedom from relapse or rising prostate-specific antigen rate for these patients was 41%, 25%, and 19% at 5, 10, and 13 years, respectively. Distant metastasis and local recurrence occurred with a 10-year actuarial incidence of 44% and 51%, respectively. With a median follow-up of 6.2 years, the 5 and 10-year overall survival rate for those treated with radiation and ablation was 92% and 67%, respectively. The freedom from relapse or rising prostate-specific antigen rate in these men was 91% and 80% at 5 and 10 years, respectively. The superior outcome for combined ablation and radiation was substantial and statistically significant in the univariate and multivariate analyses. CONCLUSIONS: Early androgen ablation alone has little curative potential for node-positive prostate cancer. The addition of prostatic radiation to ablation resulted in substantial and significant improvement in disease control and patient survival.

Zagars GK, Pollack A, von Eschenbach AC. Management of unfavorable locoregional prostate carcinoma with radiation and androgen ablation. Cancer. 1997 Aug 15;80(4):764-75.
BACKGROUND: This study attempted to define unfavorable locoregional prostate carcinoma and presents the results of treatment with combined radiation and androgen ablation for these patients. METHODS: Of a group of 938 men with clinically localized N0/NX disease treated with radiation alone, an unfavorable category included all men with prostate specific antigen (PSA) > 20 ng/mL and all men with 10 < PSA < or = 20 ng/mL but with Gleason's grade > 7. One hundred and eighty-five such men treated with radiation alone and an additional 100 men with similar disease received radiation with early androgen ablation. A second cohort was comprised of 229 men with lymphadenectomy proven pelvic lymph node metastases, with 185 receiving early androgen ablation alone and 44 receiving androgen ablation and local radiation. The outcomes, with recurrence or rising PSA as the endpoint, were compared among these various treatment groups using multivariate techniques. RESULTS: Disease outcome with the combined modality treatment was dramatically improved in both cohorts of men. For those with unfavorable N0/NX disease, the failure rate at 5 years decreased from 82% with only radiation therapy to 15% with combined treatment. Likewise, for patients with lymph node disease, the failure rate at 5 years decreased from 58% with only androgen ablation to 10% with combined treatment. For the whole group with unfavorable disease (unfavorable N0/NX and lymph node positive disease) the 6-year failure decreased from 71% with single modality treatment to 13% with bimodality treatment. There was a close relationship between the incidence of lymph node disease and prognostic categories and patients with otherwise unfavorable disease did not have their poor outlook ameliorated by undergoing a negative lymphadenectomy. CONCLUSIONS: Unfavorable locoregional prostate carcinoma can be recognized on the basis of pretreatment PSA level, T category, and Gleason's grade without specific evaluation of pelvic lymph node status. Combined local radiation and androgen ablation for patients with unfavorable disease results in a substantial improvement in disease control compared with that achieved by either modality alone. The authors found no improvement in survival because all groups of men had a normal life expectancy to at least 5 years.

Ralph (or anyone), do you know of any studies using ADT with and without _salvage_ or _adjvunct_ radiation? I am sure that RT is helpful (as is RP) in getting rid of a lot of cancer even when node-positive. I am not so sure that RT is truly useful after an RP has removed most of the tumor.

RV>++++++++++++++> Laurel, The fact that surgery removed the bulk of the cancer might be important in the overall picture, but the situation now is dealing with the residual disease (if any). The two studies mentioned deal with the improved results of the combined therapies over each individual therapy in case of aggressive disease and positive lymph nodes. This is another decision that needs some input from the radiation oncologist and you two to consider.
It was good to see that today's PSA was down to 0.04 ng/ml. It is possible that the 4-week PSA was affected by a slow clearing rate after surgery.
The normal effect of Casodex is to block the androgen receptor and with that there is an increase in the serum level of testosterone. Another possibility is that elevated serum hormone levels have been reported after radical prostatectomy. Source: Miller LR, Partin AW, Chan DW, Bruzek DJ, Dobs AS, Epstein JI, Walsh PC.

I specifically asked at Oppenheimer but the pathologist refused, said it wouldn't make any difference to his treatment. I don't know if its too late to run them from the RP.

I'm pretty sure it can be done from the rp specimen. On the other hand...I see from another post of your's that Steve appears to be responding to HT. Usually RT resistant tumors are also HT resistant. So his response to HT would suggest that he would respond to RT as well...Ron
