Alex, you ask a lot of great questions doing a good job keep it up
Extraordinarily useful, state of the art information! What a gift your videos are to those of us dealing with prostate issues. It pains me to think that most men do not have the significant advantage of considering the knowledge and treatment protocols outlined in your videos. Thank you Alex & Dr. Scholz. A donation is headed your way.
Thankyou. I managed to get PSMA Pet scan from the NHS as I kept declining Nuclear Bone Scam to check if any spread. Seeing oncologist next month for results.
I just got my PSMA Pet scan at UCLA it's a very expensive test, in Florida they wanted to charge me $124000 at UCLA I paid $6300. Insurance usually won't cover it because of the cost, I'm self pay.
The results were amazing, I had prostate cancer with 3 tumors in 2018 I opted for Cyberknife radiation in Miami, which is 5 days of high intensity radiation using markers in the prostate. It took 2 yrs for my PSA to get down from 13.6 to .85 . Then this yr my PSA started climbing and back to 6.7, so I decided to do the PSMA scan . The results were a new tumor in the prostate and no metastasis however the PSMA showed up in salivary glands, hepatic lobe and thoracic aorta, so this test can show potential of new cancer or whatever I'm not a doctor. Anyway, I would highly recommend this scan so you know what is going on and potentially coming up and get appropriate treatment.
Pretty sure medicare covers it.
There are some typical locales that will turn up as positive in a PSMA but NOT actually indicate prostate cancer. The very experienced radiologists know these areas and will indicate appropriately on the report.
I have Cigna Medicare advantage insurance. Had a PSMA PET scan. My cost was $150.
bestaircraftdeal,are you comfortable sharing what the final outcome was?
@iamric23 yes finishing up my last few days , took my PSA today and will have results Monday so let's hope it had some effects
When halting ADT and then relying on PSMA PET scans to detect any future metastatis is there any advantage getting scanned on new 2nd generation high resolution PSMA Scanners (Quandra) which are 10 times more accurate (?) than first generation PSMA PET scanners? I am Gleason 4+5 with low level mets to distant lymph glands. After treatment with ADT, Chemo and radiation I have had undetectable PSA for past 6 months, If and when can I drift off ADT? My oncologist said never! After being diagnosed with PC, PSMA PET scans are free in Australia.
great stuff as usual and clearly explained ,a Dr. here
Your videos are so informative and helpful. Thank you
I would like to request a video about the differences between the various PSMA PET scans. Some are Gallium-68 but many others are F-18 (Florine).
Age is 73. I had urinary symptoms very much like BPH. My pre-treatment peak PSA was on 3.9 and the last one (before treatment) was 3.7. My urologist wanted to assess the true size of my prostate which seemed only slightly enlarged. DRE from both GP and urologist negative. An MRI was ordered. Prostate was only 42 ccs, slightly enlarged; however, the 1.5 Tesla MRI resulted in a PIRADS-5 finding. Ensuing systematic biopsy found cores 70% and 80% carcinoma on left side; right side of gland clear.
Later, a F-18 PSMA PET scan revealed no spread, but the cancer barely showed. A quote from the findings: "Subtle left peripheral zone prostatic uptake at 4.4 SUV max". Interestingly, the scan showed many other features of my body that were thankfully free from apparent disease.
From what I have read and heard, Gallium scans are the best because they have much more contrast. But Gallium-68 is hard to get. In southern California, UCLA is the only medical center to provide Gallium. I listened to numerous talks on UA-cam about PSMA PET scans but the speaker does not make clear which kind of scan.
Please make a video explaining the value of all these various PET scans.
Thanks...
Thanks for your presentation.....had a MRI guided biopsy then a PSMA PET scan ..a small tumor on right side of prostate non metastatic 4+3 unfavorable intermediate...just finishing up a 44 course of radiation plus on 6 months of darolutamide as part of the Intrepid study..in working with Dana Farber ... I'm on Medicare
So why don't they just order psma pet scans before biopsy I just don't understand why I do understand because it's a big money game and a big Insurance brawl
Thank You. Thank You. Amazing this info arrived for me as I decide on treatment. Being pressured for surgery or radiation but focal may be fine.
Hi there from Australia..Recent diagnosed with Intermediate Contained cancer with a Gleason 4+3 and PSA 6.3..Biopsy showed 3 Positive Cores. Urologist wants to do full Radical Surgery Removal.Im 64 n Fit n Healthy..This was an absolute shock and im struggling to deal with the situation..The radiation Oncologist said 5 weeks of daily Radiation and Hormone treatment..My main concerns are of course Side Effects and ReHab.. Cheers, Thanks.. Love your Insight.
I had a similar diagnosis from my Urologist about radical surgery, however I am returning to Sperling Medical in Del Ray Beach Florida whom is a specialist in 3T MRI and targeted biopsies, and focal laser ablation.
He said he had a 90%+ success rate of no side effects.
I am going to proceed with focal laser ablation next month. The process is repeatable if micro metastases occur down the road.
Radical prostatectomy was way beyond what I was ready for.
@@db_carguy4833 Hi there. I have a similar diagnosis and recommendation from urologist (Prostatectomy). What is your experience with Dr. Sperling? I am considering consulting with him. Thanks in advance.
excellent. Thank you
Thanks again for the invaluable information. I'd like to hear Dr. Scholz weigh in on the 2023 Japanese study conducted by Yorozu, et al.cited and by Dr. Ankit Agalwar in the most recent video conference, The study involved men with high-risk prostate cancer who underwent combination therapy with brachytherapy, EBRT, and a course of either 6 month or 30 month ADT. The study followed the men for over 9 years and showed similar outcomes for both the 6 month and 30 month administration of ADT.
What about using PSMA PET for Active Surveillance? Rather than additional biopsies
My husband's Mayo Clinic oncologist has told us that another PSMA PET scan would only be done if his PSA starts to rise. He's been in remission for over two years, with a negligible PSA. PSA rechecks are done every 3 months. (Initial diagnosis: Stage 4, low volume. Treatment: 26 rounds of radiation and continued ADT therapy.)
This is a good idea. You should go for it if you can afford the cost. Keep in mind that they will do a CT scan at the same time too, so you can have both images at the structure and molecular levels to gauge the progress of the cancer.
Not accurate when you only say they are 'disease specific'. I lit upon the spine, T11. Had a biopsy and it came back negative. However, very informative video as usual. Thank you.
Dr. Scholz states that PSMA scans can occaisionally have false positives (starting about 3:08).
PSMA showed it positive you mean but biopsy did not ?
I think they do not answer to the comments, but have a look at them. So I would like to inform them that , in Paris, France, I have been told by a radiotherapist that it was just forbiden to give a psma pet-Scan to look for an outside extension of the disease, in "first line". It's only possible on a recurence of the cancer...what a pity. So I had only a choline Pet-Scan.
OK. Would beam without the hormone be acceptable for a contained tumor?
It should always be the patients decision, not something dictated by the doctor alone, unless you are being treated like a concentration camp inmate, like the ALBERTA CROSS CANCER INSTITUTE treats us.
Be assertive and demand some say in your treatment, or fire your doctor.
If you have serious health issues like a heart condition, you may well decline their ADT CASTRATION and avoid its quality of life destroying horrific side effects.
Carefully weigh benefit vs risk and demand full disclosure so you can give FREE AND FULLY INFORMED CONSENT
Please send yours excellent informations with subtítles. It helps a lot.Jose Padilha Rio de Janeiro.
So How is a Targeted Biopsy Conducted?? What's the Process??? And what the Heck is Focal Therapy??
After prostectmy and radiotherapy my PSA continuously rose for 18 months but last time almost 2 months ago my PSA dropped from the last time oe 3 months back..sir why my PSA dropped
I may have missed this in the video, but it seems to me that one huge difference between a needle biopsy and a psma pet scan is that the needles can detect cancer inside the prostate but the psma pet can't (because the membrane of every cell in the prostate has oodles of psma so the cancerous cells wouldn't be differentiated from noncancerous ones). Am I wrong?
@@koof1776 Why?
@gshenaut 95% of the time PSMA lights up cancer cells from head to toe, no difference from bone to liver to prostate.
