Anyone have a high testosterone after SBRT?

[Yearofthecow]

In September 2022 I had image guided SBRT utilizing ViewRay Technology for a 3+4 gleason grade, low decipher score, PSA 2.7 before treatment, on Avodart for BPH.

Been monitoring PSAs and Testosterone every three months, and remaining on Avodart.

During this time my PSAs and Testosterone values have been the following at Stanford:

PSA Testosterone Comment

8/9/2023 2.7 Before Treatment

12/2/2022 .92 1277 After Treatment

3/2/2023 .40 1069

6/9/2023 .49 1341

On 12/2/2022 I also went to LabCorp just to see how the values compare to Stanford labs, and received the following values, PSA = .9, and Testosterone = 960.

Even though I am still taking Avodart, which I believe can increase Testosterone, because Avodart blocks the conversion of Testosterone to dihydroTestosterone, (DHT), that would leave more testosterone because it doesn't get converted to DHT.

It seems that the Testosterone is too high, even taking into account the possible Avodart effect.

I have no side effects from treatment, and because of my Decipher score, Gelason grade and volume, the radiation oncologist saw no need for any ADT.

I thought Testosterone was supposed to decrease after radiation treatment.

Curious if others who had radiation treatment without ADT, experienced a high Testosterone?

Thanks,

John

You no longer need Avodart. Stop taking it and see what your testosterone does.

Thanks Allen. Have an appointment with Dr. Kishan next week and will ask him.

I suspect I will get a rise in my PSA when I do that, so I will prepare myself for that
