Prostox - learn about whether radiation will cause problems

Posted by Jeff Marchi @jeffmarc, 2 days ago

The Prostox test evaluates whether or not you will have side effects from having different types of radiation.

PROSTOX works not just for first time radiation but for recurrence and maybe even radioligand therapy like Pluvicto. By analyzing your unique genetics, you can make smarter, more informed decisions to avoid side effects and safeguard your quality of life for years to come.
PROSTOX Standard (previously PROSTOX CFRT+) predicts late grade ≥2 toxicity from conventionally fractionated (CFRT) or moderately hypofractionated (MHFRT) radiation therapy for patients with localized prostate cancer.
Together with PROSTOX Ultra, which is already available for patients considering stereotactic body radiation therapy (SBRT), the PROSTOX portfolio now provides risk assessment across a broader range of external beam radiation therapy (EBRT) types.
We'll discuss the updates and other patient concerns such as insurance coverage and questions to bring to your doctors.
Join us April 27th, 2026 for a special presentation by test developer, Dr. Joanne Weidhaas, 7:00 - 7:55 pm Eastern - Dr. Weidhaas Presentation in the AnCan Barniskis Room

You do need to Goto meeting installed in order to attend this event

Just put Barniskis for the session to join

@charlesprestridge The associated website, MiraKind, has a FAQ that among other things says Prostox has not been validated for brachytherapy. https://mirakind.org/prostox-testing/

They are investigating. I called them asking if I got the test and then had 20 sessions of external beam plus a brachytherapy boost, would they be able to use the data for a future validation. They said no. They have a selected group of patients for validation.

The Dr. Joanne Weidhaas who will be presenting at the upcoming AnCan GoTo meeting, was interviewed by P.C.R.I. about 8 months ago.

Prostox was the pivotal test in my choice of RP. I was leaning towards SBRT, but the Prostox results put me at high risk for both SBRT and IMRT. I'm almost 3 months post RARP and my continence is almost fully recovered. For me, RALP was the best choice.
BTW, the test cost me nothing due to my zip code. Check with the Prostox company and there's a very good chance that you can get the test free or at a discount.

@quaddick Hi Quaddick! Like you, my husband is one of the "rare" 1-2% who Prostox scored "High Risk" for both SBRT and CFRT/IMRT.

Last week he successfully underwent TULSA-Pro. Six days later he got his catheter out! ....Thank you Prostox.
