PSA doubling time

Hi all

Just thought I would ask is there any collation between PSA doubling time or aggressive PC and how long hormone drugs will last.

Im currently having salvage radiotherapy but my doubling time was 4 to 5 week and my gleeson score was 4+3 when i had my prostate removed March 16.

I know everyone is different I just thought I would ask

Cheers

Gary

Hi Nuray good with it all m8

I just wondered if having a short PSA doubling time would mean the hormone drugs would have a lesser affect or if that didn't matter.

Cheers

Gary the hormone injections should stop yr body producing testosterone?which the cancer needs to thrive on m8t?change yr diet cut all sugar as cancer thrives on sugar and red meat dairy all those things aren't helping you at all mate?Ive changed my diet m8t greens all veg any thing green cancer hates stops them multiplying m8t?read up on cancer and diet?

in reply to Nuray

This is great advice and my beliefs and practices are the same.At first it seams drastic. But I belive nessessary...

PSADT < 6 months is scary fast. A month is virtually terminal, and justifies doing everything remotely possible to extend your life. Surgery, radiation, ADT, chemotherapy, calorie restriction, intermittent fasting, medical marijuana, and Dr. Leibowitz's three-pronged protocol (Google it) all come to mind for starters. You need to pursue all the above this week if you want any chance at a few more years.

Think about it. If your PSA is 1 and your DT is 1 month, by this time next year your PSA will be 4,000. IF your ADT (hormone therapy) works well, it will buy you some time, but it also drives prostate cancer towards castrate resistance, which is terminal.

Get cracking.

It's a battle to survive and not for the faint of heart..But many ,many people had it worse and some have gone into remission for good others for many years .For me they project a return in 4 yrs,told that maybe I can make 5-6-7 if lucky by being vigilant in my own care, as I have been from the start.Go with you gut and stay aggressive if you have an agressive disease.You can win.

Don't accept maybe 7 years. I understand all the nutrition, which is good. But don't neglect mainline medicine either, a good urologist or oncologist on the medical team is wise. I was given 5 years with my profile; however, that was 18 years ago. Your wise to read and be part of your medical team.

Is the Salvage Radiotherapy to which you refer on the backside of having RP or Initial Radiation Therapy or something more far removed from initial Tx.... Since you post was from some time ago I will ask if the Salvage Therapy did you any good.... I'm trying to decide which way to go myself right now....HATE the idea of hormones if there is any other alternative....

Gary,

I'm not an expert and can't give you any advice beyond a suggestion for something to talk to your doctor(s) about.

You haven't said what your last PSA reading was. If, for example, you went from a PSA of 0.01 to 0.02 in four weeks, I'm inclined to think that you don't really know your true doubling time because, at that low a level, concentrations of PSA in the blood are so tiny that precise measurement is not possible. Also, the tiny amounts of PSA created in the adrenal gland are a factor. On the other hand if you went from a PSA of 4.0 to 8.0 in four weeks, you are probably looking at very serious numbers. The fact that you have been offered salvage radiation (it's not usually offered to men for whom distant metastases are strongly suspected), and that your Gleason score is 4+3 and not, say, 5+4, makes me suspect that your PSA numbers were low and hence might not be as awful as the calculated doubling time looks. But, of course, I could be totally wrong.

Now for the suggestion.

Assuming that the radiation does not solve the problem (the odds are generally less than 50/50 that it will), I suggest that you ask about the possibility of getting early chemotherapy along with ADT. Here's why: First, the CHAARTED and STAMPEDE clinical trials (look them up) suggest that, for men with aggressive cancer, a combination of ADT + chemo extends life significantly longer than ADT followed by chemo after ADT failure. Secondly of course, if your doubling time is indeed short, that's an indication of aggressive cancer and makes you most liable to benefit from early chemo.

I don't know why patients with aggressive cancer do better with early chemo, but I can make an educated guess. Chemo damages or kills cells that are dividing. A short doubling time indicates that a high percentage of your tumor cells are dividing at any given time and hence are vulnerable to chemo.

If your doctor says "Well ... let's just try ADT and not worry about chemo for now", and he won't read the trial results, I'd go and start the ADT but start looking for a second opinion to see if starting chemo before the ADT stops working is advisable.

Another option is ADT plus immunotherapy. I think some day that will turn out to be a real winner, though for now immunotherapy drugs are still new and not fully developed and it's ADT + immunotherapy is experimental. We don't yet know whether it's as promising as theory might make it seem.

Finally, it's not a bad idea to noodle around on the clinical trial websites.

Best of luck.

Hi my PSA went from .1 to .2 then .35 then .7 before my Radiotherapy started

AlanMeyer profile image
AlanMeyer in reply to Chubby42

Assuming those numbers are a month apart then that does indeed look like a one month doubling time.

Best of luck with the radiotherapy.

Mine went from 1-2, to 14, to 29, over 5 weeks. 3 psa's. I'm real happy Zytiga works.

Stampede Clinical Trial was essentially set up from the Charing Cross Hospital Oncology team here in London. Google (as you know) Stampede Clinical Trial. Results say hit the bloody cancer fast and hard. My Onco lead on the team. She's great. I am not on the trial but sure I benefit from results. I used to box, hit hard from the start and give yourself time to see what you are facing. Charted also for us patients to study as you recommend. David

Hi Alanmeyer my PSA went up after my RT from .7 to 2.1 ;-( and i have been told i cannot have chemo with ADT as my cancer has not yet spread to the bones or lymph nodes.

My last PSA reading has gone from 2.1 to 2.9 so i does seem to have slowed.

Cheers

AlanMeyer in reply to Chubby42

Chubby42,

I'm no expert, however if you were given salvage radiotherapy and your PSA went up in spite of that, I would think that indicates that you DO have metastatic disease, i.e., cancer that has spread to the bones or lymph nodes. If the prostate region itself was radiated but the cancer grew anyway, it seems likely to me that the cancer that was growing was not in the radiation field. It was somewhere else. Otherwise the radiation would have blasted it.

I don't know if chemo is the right thing for you or not, but the reason you were given for why it's not didn't convince me. Maybe you should see another oncologist for a second opinion, especially in light of the CHAARTED and STAMPEDE trials which appear to me to indicate that early chemo combined with ADT extends life longer than waiting.

Best of luck.

Alan

Hi Alan yep i couldn't agree with more, ill try to see another oncologist but on the NHS not sure.

It does make a lot of sence in what your saying.

Altho the RT must have hit something as my PSA doubling time went from 4 weeks to 3 to 6 months ive only had the one slower reading so waiting on more blood test over the next couple of months.

Sorry ,that question is beyond me,others will know .Was not a candidate for sugery. The fact that you were is good.It means that it's hopefully contained inside the prostate.I was told that all of these ADT drugs will fail in time,then they would move me to others.I don't understand. is your P. S. A. Doubling ?Please let me know.One good thing for us is if we extend ou time there's new stuff coming out all the times.so in a few years ,I belive more and hopefully better thingsWill come up ..

I too was told at DX that I was not a candidate for either radio or surgery. Too many bone mets (30+) and pelvic girdle lymph nodes all ravaged. Sufficient radio to kill bones cancer would kill me. Now just 1 bone met left after 3 years all pelvic girdle clear. No new mets. PSA down from 200 to current 0.06. I am an optimist like most of us and our carers but very aware of what may be waiting for me. David aged 71 fit and well. No

I love to read stories like this. 30+ bone mets down to 1. 200 PSA down to .06. All proof that sometimes the medicine does just what we hope it will do. It give encouragement to others.

I know for sure DAN59(DAN-please correct me, if its wrong), positive, firm, motivated---in ten years--still counting-skiing- metastatic, psa 50, Gleason high, just no need to feel discouraged. with strong positive mind, you can change organics inside, each case is unique, but lots of medicines, please stay in touch with expert doctors, I have seen splendid results with mskcc, md anderson, dana faber. two school of thought, chemo+adt or adt alone. however in low volume, thin metastatic spread, less than 5 lesions in bone, only adt preferred with SBRT.

be aggressively strong, you may live as long, as you are determined to !!!!!. be blessed.

Thanks for the replies people my PSA went from .1 to .2 then .35 then .7 all 4 weeks apart, I was told with a gleeson score of 4+3 I was medium aggressive it seems to be worse than that to me.

.7 was the last reading before i started radiotherapy still have 2 weeks to go on that.

Cheers

Gary

lupron (GnRH agonist) or possibly faster acting degarelix (GnRH antagonist) should be (i feel) taken as soon as possible. A doubling time of a month means that something somewhere is growing very fast. A PSMA scan to locate a possible single site would have to be considered as a very helpful option, to guide local therapy, one might hope.

EDIT: (ah yes) You need to verify that the doubling time is indeed a month, after the current treatment. If you are seeing an oncologist and radiologist, I feel confident that they are aware of most of what we are aware of. Maybe not the J591 trial, and like that.

I had prostatectomy (with PSA 8.5 and Gleason 10) 9 years ago. When PSA rise began again, I had radiation therapy 8 years ago. Went on double continuous ADT 27 months ago (with PSA risen to 5.4): Bicalutamide daily and 3-month Eligard shots under Johns Hopkins clinical trial. Undetectable PSA since then. Next appt April.

Yes, doubling time indicates progression. Gleason score indicates aggression. Talk to the Oncologiest.

Chubby with the "Cheers" salutation I guess that that you are in the U.K. My treatments was in the States. Alan Meyer mentioned early chemo. I know Alan and he knows that I am one who benefited from aggressive treatment with chemo.

Gleason 7 (4+3). After seeds and external radiationmy PSA never came down. At about ten months after primary treatment, PSA rise from 6.5 to 18.00 and finally 32.4 with metastates at two sports if my spine. I immediate had an injection of Lupron and a month later started a six month chemo trial. That was thirteen years ago. I remain undetectable and haven't had an injection of Lupron since February 2010.

It sounds like you have Advanced Prostrate Cancer and inquiry into a chemo and hormone regime is not out of line. In summation, I went from 2-4 years life expectancy thirteen years ago to, I'll die of something other than PCa. I am 79 years old. Good luck. And, stay aggressive and keep kicking the bastard.

Gourd Dancer, My treatment and PSA rise was very similar to yours but my doctors had no communication skills and just told me to get chemo without explaining why, or giving anecdotes like your success. Thus, I didn't get the chemo. Do you have any thoughts on why doctors say to start chemo at the very beginning with ADT or wait until last resort treatment. Why couldn't the chemo work/have an effect while ADT is still effective at suppressing the PSA? I've been on Lupron for almost three years now. I'm feeling some frustration that my MO at Duke might not be aggressive enough. Says chemo wont do me any good now. It seems like doctors never want to use a treatment unless it was 100% proven in a study instead of using assumptions like chemo works at the beginning of adt so it will likely help a few years later but probably not as much as at the beginning.

Is your MO at Duke Dr. Armstrong? I think he's excellent, but does lean to the standard of care, less aggressive side. I have just hit MCRPC and he recommended Enzalutamide, Aberaterone and finally Darolutamide. Said it should buy me about two years. I am BRCA2 positive and he is aware of that. My MO at Wake Baptist agreed with my suggestion, that I should go straight to a PARP inhibitor via clinical trial. I hope to start as soon as my psa hits the qualifying nadir.

GeorgeGlass profile image
GeorgeGlass in reply to hadleycash

Yes, it is Armstrong. I just wonder why people all over this site are getting things prescribed, like: doxycycline, Avodart, casodex etc. in addition to Lupron but he always says there is no evidence that it extends effectiveness of Lupron. He might be right but it seems frustrating to me because there seems to be studies showing that multiple drugs extend castrate sensitive time period. The HIV victims ended up with success by taking drug cocktails so why wouldn't a cocktail of drugs help extend our lives?

What is he recommending? That you use all 3 of those drugs sequentially? He tells me my ideas have no evidence but it doesn't seem like his recommendations are scientific in terms of when to use and in what order. I realize there is an art to when to use these drugs but I don't like when they use art for what they want but they use the "no evidence" card when I present some of these supplementary ideas to him.

What is different for people with BRCA2 in terms of what treatments you should get and when? That's what the PARP is for right?

I don't know if I like the use of the "that should buy us 2 years" comment. He said the same thing to me about Nubeqa or Xtandi. First of all, there is no way to accurately predict those time estimates of 2 years, and secondly, why only two years? There are people on this site getting 10 years out of Zytiga.

I have had a one month dt whenever not on hormone therapy. My Gleason is 4/5. I was diagnosed just over 5 years ago... so there is hope mate! First... I recommend you get genetic testing done. It could reveal treatment options you wouldn't know about if you have such things as repair deficits like BRCA1/2. You have a 4/3 Gleason... think of it more as aggressive because it's not 3/4! The odds are that you metastatic cancer is primarily 4 because that's what travels and metastasizes faster. That's why you doubling time is so fast. Go to clinicaltrials.gov and see what all the options really are. Read everything you can and be you own best advocate! Best wishes my friend.
