Lupron Treatment Duration: How long were you on it?
I have been diagnosed with Grade 3 prostate cancer with a 4 + 3 Gleason score of 7. This after having 2 PSA scores last year between 4 and 7. The cancer has not spread to the bones. I have received two Lupron injections 3 months apart and will complete 28 radiation treatments in the next couple of days. No surgery. I have tolerated the Lupron shots well with few but manageable side effects. I have an appointment to receive a third Lupron shot next month. My first PSA test after completing radiation won't be scheduled for 3 months. From researching Lupron, it appears that this is used for advanced stages of prostate cancer. From what I was led to believe, I was not advanced. My question: How long and how many Lupron shots might I need to go through? I will have this discussion with my urologist hopefully before proceeding with the next shot. Thanks for any information provided by the group.

I'm 82, good health, Gleason 8-10 and I have been on Lupron and Zitiga for 10 months. PSA declined from 24.0 to 0.44. Recently I have experienced mild headaches. I have considered three treatments - Protron, Brachetherapy and IMRT. I expect to make my decision by the end of December. No therapy is perfect and, in my opinion, either of these three treatments would be a good choice. I anticipate the Lupron and Zitiga will continue for two more years assuming I have no additional side effects.
For what it’s worth, I was on a ADT for almost 11 years. During that time we were never able to get my PSA below 2.0 and periodically it would get up to as high as 10 to 15. About two years ago we added Zytiga (an antiandrogen drug) which helped for a while. Two months ago, I became so tired of having to get injections every three months with Lupron or Eligard, that I decided to have a bilateral orchiectomy. Sadly, my PSA is continuing to rise, up to about 8 now, even with no circulating testosterone, except the little bit that comes from the adrenal glands so I am no longer on ADT, per se. but I am still getting Zytiga. To the best of my knowledge metastatic prostate cancer is not curable so all we can do at this point is try to control it and hope that someday a treatment will come along that can cure it before it takes us down. My oncologist says that prostate cancer cells eventually figure out how to do without testosterone, and/or create their own. Meanwhile, I’m relegated to treatments that will hopefully find and eradicate the existing cancer cells in my body, looking at radium 223, chemo and Pluvecto currently.
My best wishes and prayers go up to all you guys who are struggling with this seemingly never ending battle!
There are various schools of thought on the use and length of Lupron. I will give my clinical history (see attached). After surgery and SRT failed and with clinical data showing an aggressive PCa, I chose triplet therapy when the C11 Choline scan showed four PLNs but no bone or organ involvement. The treatment plan Dr. Kwon recommended included 24 months of ADT, six cycles of taxotere and 25 radiation treatments, 45GYa to the PLNs, all of them, with boosts and wider margins to the four identified in the scan.
Given my response to the treatment and various articles I had read about 18 vs 24 vs 36 months of Lupron, I asked if I could stop the Lupron at 18 months, Dr. Kwon agreed.
You say you did RP and 40 rounds of IMRT, was the IMRT to the prostrate bed as is generally done in SRT when you have BCR after surgery? if so and you have PCa in the PLNs then do some homework on doublet and triplet therapy.
You could do six , 12 or 18 months in combination with ADT, if your response is positive, PSA drops to undetectable and stays there, you could stop the Lupron and then actively monitor through frequent PSA tests and consultations with your medical team. If, when, you do stop, decide what the frequency of those lab tests and consults would be, maybe initially three months and adjust longer or shorter depending on the results. Have decision criteria about when you would go back on treatment, at what PSA would you image, how many test results and how far apart indicate PCA is on the move again...
As a general rule, men on ADT do at some point become castrate resistant, the questions is how long is that? If you're familiar with statistics and the Bell Curve, you'll understand some will get very short periods, other very long, most somewhere in the middle.
If you are doing ADT, consider asking your medical team about Relugolix - https://www.cancer.gov/news-events/cancer-currents-blog/2021/fda-relugolix-prostate-cancer-androgen-deprivation-therapy#:~:text=Relugolix%20is%20known%20as%20a,that%20patients%20take%20every%20day. It does not have the flare Lupron does, better CV and Metabolic side affect profile and T returns faster than when you stop Lupron. It can be more expensive depending on your insurance and requires greater self disciple since you must take it daily at home vice a 1, 3, or six month shot in your medical team's office.
You don't talk about the radiation treatment plan but if you are meeting with a radiologist, discuss the total dosage, treatment fields and boosts to the sites identified in the imaging.
If you are doing 18-24 months, you could assess whether or not the single ADT agent drops your T to <20, ideally <7, if not, you could add a 2nd ADT agent such as Zytiga, Xtandi...Lupron shuts down the T produced by the testicles by some is produced by the Adrenal glands and there are ADT drugs which shut that down.
I’ve been on Lupron since 2016. My cancer became Hormone Resistant last year (2021). I went to LA for PSMA PET scan which showed four pelvic lymph nodes with cancer. I underwent 5 SBRT treatments in January of this year (2022). Current PSA is <0.008. I am still getting Lupron shots, two per year, and taking Nubeqa. I will follow this regimen for 12 more months, when I will try to wean off all treatments, carefully watching the PSA for any return of my cancer. Feeling hopeful. I was first diagnosed in 2001. I’m a believer in the new more sensitive scans. Best wishes to all.
@haft2hunt, I'd like to add my welcome. Your question about length of time of ADT with metastatic prostate cancer is something members often ask about. For this reason, I moved your question to this existing discussion:
- Lupron Treatment Duration: How long were you on it? https://connect.mayoclinic.org/discussion/lupron-treatment-duration/
I did this so you can read through previous posts and connect easily with members like @web265 @rxharleydude @spryguy @craigc @scullrower @melcanada @yell0wsub @ken1946 and many others.

It's such a confusing burden to have to weigh treatment options with so many unknowns.
This won't help much but, I'm interested in your research here. I think you are basically correct, it's more of a delay tactic than anything else.
From what I've found ADT seems to just starve/weaken the cancer cells so they can't multiply but doesn't actually kill them. My guess is it's believed that weakening the cells this way may make IMRT and other radiation protocols more effective.
If this is correct, then yes the time on ADT does seem arbitrary. My surgeon wants me on ADT for two years but doesn't really give a good reason as to why.
My radiation oncologist seems ambivalent on the subject and tells me ADT only accounts for a 3%-5% better outcome when taken with IMRT. I did see stats that suggest 18 mos to 2 years is 35(ish) % better than 6 mos, but if that only applies to 3%-5% of all patients anyway......?
If all this is true, taking it for two years seems to be for the purpose of letting you have that time with little or no cancer growth, if there is any cancer left. So, are we just postponing the inevitable by taking this? Creating time for better treatments to hopefully come along?
Unless somebody here or on my team convinces me otherwise. I'd rather stop at 18 mos, (seems to be a new common time frame) and see what happens. at least if I'm not resistant, I can go back on it, if the PSA starts to climb. No?
Sorry I couldn't offer more help / info, I'm just going down the same road mentally and I'm interested in others opinions on this as well.
Best of luck to you!
So speaking with my medical oncologist, staying on ADT for 2 years is an arbitrary number. No one knows. I have Mets to my lymph nodes. Did RP and 40 rounds of IMRT.
If I stop at 2 years, I’m playing the waiting game for it to pop up anywhere in my body.
If I continue it indefinitely, I risk becoming castrate resistant.
So confused
Help
So does Lupron.
