Hi-Risk/Recurrent/Advanced PCa Video Chat, Apr 4, 2022
Next meeting will be on Apr 12, 2022.
All AnCan’s groups are free and drop-in – join us in person sometime! You can find out more about this and our other 10 monthly prostate cancer groups at https://ancan.org/prostate-cancer/ Sign up to receive a weekly Reminder/Newsletter for this Group or others at https://ancan.org/contact-us/
Editor’s Pick: Heads up for a marathon session this week. And we keep returning to 2 topics …. intermittent hormone therapy (IHT), and of course Pluvicto (rd)
Topics Discussed
original low Gleason progresses to advanced PCa over 21 yr period; do you buffer on resuming IHT; Epstein reclassifies 3+3 to 5+4 with treatment implications; weighing time to Pluvicto availability with a trial now; stay with chemo or shift to Pluvicto?; Herb’s last man under the wire; starting darolutamide (Nubeqa); how long before testosterone returns?; after 5 yrs it’s time for IHT; side effects from chemo; post-Pluvicto – abi, Provenge, or …? ; alternative advanced disease markers; scan concordance is important for Pluvicto; vertebral fracture with advanced PCa may have implications.
Chat Log
Peter Kafka – Maui (to Everyone): 5:23 PM: Has the doctor suggested a PSMA scan while the PSA was up?
Len Sierra (Private): 5:39 PM: Rick, I’ve actually been on complete drug holiday since Jan. 12 of this year, so almost 3 months now. No Lupron, no daro.
Stephen Saft (to Everyone): 5:42 PM: my doctor told me it wouldn’t get approved but I fought for a long time and finally got him to put it through. It was approved and I had the Pylarify PET scan on March 4.
John Birch (to Everyone): 5:58 PM: Stephen, why the the doubt on insurance approval? Thats the isssue I am running into.
Frank Fabish – Ohio (to Everyone): 6:00 PM: Amir Mortazavi at OSU James Cancer Hospital
Stephen Saft (to Everyone): 6:00 PM: That is a very good question. I don’t know. I think the old school thinks that it won’t change treatment so the oncologist doesn’t like the idea.
Len Sierra (to Everyone): 6:23 PM: Steve, the half life of Ac-225 is 10 days and it takes 5 half lives to clear 95% of a drug, so you’re looking at 50 days of washout.
George Rodriguez-Chantilly VA (to Everyone): 6:29 PM: Rick, I need to drop off. Very informative. I’ll reach out later to get some information on what to expect with hormone treatment of Yonsa w/methylprednisolne in concert with Eligard.
Frank Fabish – Ohio (to Everyone): 6:29 PM: Rick I have to go. I have my 3 month check up and blood draw tomorrow. I’ll let you know results.
Ben Nathanson (to Organizer(s) Only): 6:30 PM: Len, aren’t these different half-lives? Isn’t drug clearance a function of pharmacokinetic half-life, not radioactive half-life?
AnCan Herb (to Organizer(s) Only): 6:31 PM: The biological half life is much faster. The unbound compound is excreted, and then the bound drug disappears with its half life. It is a two compartment model
Ben Nathanson (to Organizer(s) Only): 6:31 PM: Right, so less than 50 days
Len Sierra (to Everyone): 6:32 PM: Ben, I believe the greater concern would be the radioactive half life since that is the toxic payload.
Ben Nathanson (to Organizer(s) Only): 6:32 PM: But if it’s out of the body faster than that, it doesn’t matter if it’s still radioactive
Tony D’Errico – Cornwall, Ontario (to Everyone): 6:35 PM: I will see you all soon. bye for now.
Len Sierra (to Everyone): 6:35 PM: I guess we’ll have to consult with a nuclear medicine doc on this..
Ben Nathanson (to Organizer(s) Only): 6:45 PM: Herb, this video? “Lymphocytes as a “Living Drug for the Treatment of Cancer” and Emergence of the NIH cGMP Program to Support Patient Care Innovation” from 3/30?
AnCan Herb (to Organizer(s) Only): 6:46 PM: Yes, that should be it
Ben Nathanson (to Organizer(s) Only): 6:46 PM: Thanks!
John Birch (to Everyone): 7:08 PM: Thanks to all. Need to run apparently tornados are landing in the area.
David Muslin (to Everyone): 7:12 PM: Going to bed. See ya next week.
Stan Friedman (to Everyone): 7:23 PM: Good night. See you next week.
Mark Baldridge – Seattle (to Everyone): 7:57 PM: Thank you everyone for such good information – Kathy and Mark
Len Sierra (to Organizer(s) Only): 7:57 PM: Got to go, Gents. See ya next week.
George Rovder Arlington VA (to Everyone): 7:59 PM: Thank you all. Goodnight. George
