PET scans

[Roscoaus2000]

My psa has slowly risen from 0.001 to 0.10 over a 2 year period on Zytiga, Prednisolone and quarterly Zoladex and Denosamab injections. I have a good Qol, no side effects, sleep soundly 7 hrs a night. Am 81yo and reasonably active. Some Lowe back pain and stiffness but don’t need painkillers. Onc. Says now psa is 0.1 a pet scan may be worthwhile to see if there is limited cancer that could be zapped with R/T. 5 years ago my psa was 9000 and whole body scan showed Mets in every bone. I was in major pain and had no bladder control. Do you think it is possible I may now only have a few treatable Mets? Onc has given me choice. I am sceptical of chances and wonder whether the side effects of R/T would make it worthwhile. My overall health is excellent, BP, sugar, chol. Trygl. And liver are all well within normal range. I may live another 10 years and ultimately have bone pains from the prostate cancer. Do any of our elderly cohorts have experience of becoming disabled by advancing Mets. I have until mid January to make up my mind.

You should do a PSMA scan. Much more sensitive to locate any mets. Zap them With SBRT if they are in a safe location and continue with systemic treatment. At least do the scan and then make an informed decision. I did The SBRT twice to 4 mets zero dude affects

I can't imagine what you hope to gain by a PSMA PET scan now. You already know you have metastases in every bone. You can certainly zap any metastases that are painful. You may get better survival by using Xofigo now, if your oncologist can convince your insurance company that you are becoming castration resistant.

Thank you. I agree about the mestasteses. I said that to Oncologist. He said there was a chance that the majority may have been resolved and there are only a few causing pain.I looked at Xofigo information sheet and am concerned that the side effects may be worse than doing nothing. The pain I have now is tolerable without painkillers. I think my general health is good enough for me to live many more years but am unsure of progress of cancer pain.

Xofigo is not covered by Australia’s Medicare system and I doubt I could afford the cost.

How does one die from Prostate cancer? Is it due to it spreading into the organs. There was no indication of spread there and minor indication in the lymph nodes which resolved within 4 months of hormone treatment.

In Australia, youu should be able to get Lu177PSMA617. I know Peter Mac in Melbourne has several excellent trials.

PCa doesn't have to invade organs to be deadly.

Your doing ok. If bone mets are your primary worry have a bone scan. There are other ADT drugs to go to if zytiga is failing.

With a PSA of 0.1 most scans will not show anything. If you decide to do one , it shoul be a PSMA PET/CT (Ga 68 or Pylarify) which are the ones with the highest detection rate and they are covered by Medicare. The detection rate with a PSA of 0.1 may be less than 30%. The doctors I consult with in Germany advises me to do these scans with a PSA around 0.5.

Since your PSA is going up when in abiraterone the cancer is becoming castration resistant. You could discuss having Provenge , a vaccine covered by Medicare which has shown to offer a survival advantage.

If you do the PSMA PET/CT and there are mets you could consider getting Lu 177 PSMA treatment abroad, if financially possible. It is available in many places in Europe and India. It is a systemic treatment which offers a survival advantage . Side effects are usually low unless there is diffuse bone marrow infiltration by the cancer.

[hansjd in reply to tango65]

Unfortunately in Australia, Provenge is neither covered by Medicare nor available, however, Lu 177 PSMA is available at a cost of about A$10,000 a treatment. There are currently some trials with Lu 177 but these are limited.

[Roscoaus2000]

Thanks everyone for your comments. I do not need to do anything yet. I am seeking information on the likely progression if I do not have any fu have any additional treatment. At 81 I can accept dying. However, I would like to know the likely steps. Is there any literature describing experiences?

At 81 find yourself a Sheila and enjoy yourself............

Good Luck, Good Health and Good Humor.

Thanks J-O-H-N. Fortunately that’s one thing I do have. Over 60 years now. I am very grateful for my life. Had I got into the System, as recommended 16 years ago, would have had a prostatectomy then and no more sex life. Instead I had a good 10 years with no symptoms, I then had a poor 9 months between being diagnosed with psa 9000 and successful adt and chemical castration. I had minimal side effects to Casodex and none with Zytiga. It is my Onc. Who is urging pet scan. I am not convinced and am seeking information of what progression will be like. I can’t find any literature on progression to end point.

Well good going with her for another 60 years, lucky man.

Good Luck, Good Health and Good Humor.
