Last month my PET scan revealed prostate cancer has spread t o my bones. I have read Estrogen has been used effectively to stop cancer progress and, in some cases, has actually decreased the size of the tumor.
Has anyone used Estrogen as treatment for advanced stage 4 prostate cancer?
At this point, it could make me look like Dolly Parton and I won't care.
Hi Steven - I have not seen that article. I'll ask our MO on Tuesday.
If your PSA continues to rise while taking Eligard, and it's keeping your testosterone at castrate level, I don't think estrogen will do you any good (other than for side effects). But you should be using Zytiga or Xtandi now. If you have pain from your bone metastases, you can also get Xofigo. Provenge is indicated too.
Eligard did keep my testosterone levels down. But it was a three year treatment and stopped 2 years ago.
So I'm thinking Eligard and estrogen, plus other treatments.
It didn't stop keeping your testosterone down 2 years ago, did it? It only stopped keeping your PSA down.
No. It kelp my testosterone down
Right. So if Eligard keeps your testosterone down, there is no need for estrogen
I heard it can stop, or even reverse, prostate cancer tumor in the bone.
It does that by stopping testosterone, just as Eligard does.
Oh. That's different than what I heard. Thank you!
If I understood correctly you have not been in androgen deprivation therapy for the last 2 years and the cancer showed mets in a recent scan. I assume your testosterones levels are above 50. The cancer is now, metastatic castration sensitive.
The SOC is androgen deprivation therapy plus chemo, or one of the second generation anti androgens.
Testosterone suppression is usually done with Lupron, Firmagon or similar meds but it can also be achieved using transcutaneous estrogen patches, according to the preliminary results of the PATCH study:

This approach could have a better QOL:
Kill the T. Add novel treatment... Xtandi worked for me for a few years then radiation to bones. Lasted about 7 mo. then again and it just stabilized, then xofigo which failed by allowing 4 new mets in first 3 mo. You have lots more options open to you at this point. Good luck and keep up the fight.... Life Is Good....keep living it...
Next steps after Prostatectomy?
What next after chemo?
Just finished first meeting with radiation oncologist. What he proposed as next steps
Postponing chemo because of radiation? 
What to expect from chemo, if doesn't work what is next?
