I’ve recently been diagnosed with Gleason 9 PCa T3bN1Mx and I’m waiting for a PET scan and then hormone treatment.


I’m 56 and my oncologist has recommended Genetic testing due to my age and type of aggressive cancer.


Has anyone had this testing? I’m assuming this is merely a blood test at the GP?


I have many siblings and myself and siblings have children that could be affected by a mutated BRCA gene. I’m assuming they would need to have testing and monitoring if I have this mutation?

I read that new studies suggest or might suggest that some mutations make patients exquisitely sensitive to HT. And possibly for longer duration although I am not sure about this. I guess this knowledge will come along in the next few years because I think sequencing is part of many clinical trials and also routine at some centers in the USA. I wonder if the Halda trial Phil1969 is on does sequencing. I also just went to the Halda trial website and it looks like they could recruit for earlier stages soon if not already although I do not know about the one UK site. Most sites are in the USA. I would like to try to get my husband tested at least for BRCA in case olaparib could be an option in the future.

Hi, Lee.


For the past three years, I've been a regular on the forum. I recall a few conversations mentioning genetic testing for BRCA 1 and 2 variants, but can't remember if anyone on the forum has actually been tested?


Here's a link to our site's information on the subject.

I have quite a strong family history of PCa. My dad and my younger brother had it. I have two sons in their forties and advised them to get themselves checked out.

Hi LeeB. My husband had genetic testing which was done from the tissue they took at biopsy. Unfortunatley he was negative but at least it was tested. I had asked the oncologist for his test.

I was tested for 2 research projects. I had a saliva test and a sample of my tumor was also tested. But I think a blood test is also often done. All pretty straightforward. 


Some of the newer drugs (Olaparib?) are targeted at those with BRCA mutations. So testing may guide treatment. 


Most men with PCa don't have BRCA mutations. I didn't and that provided some reassurance for me as it increases kids risk of breast and prostate cancer if they inherit it.

P.s. if you were BRCA positive and told your wider family, I guess they'd have to decide for themselves whether to get tested or not. I'm not sure if it would be done on the NHS.

Many thanks.  I’m going to see if I can get a GP appointment to discuss this further and hopefully either get a blood test or referral for genetic testing.

Hi,


I was offered genetic testing and took it. Initially it was a saliva test, though they couldn't complete all the tests using that so a follow up blood sample was taken.


I wanted to know as I have two boys, and also a twin sister so it had potential impacts for them. Luckily my tests all came back with no mutations


 


all the best


John

Hi Lee


I was diagnosed in 2024 at 43 and genetic testing was offered after the prostatectomy. After an initial consultation with the genetics team I had a blood test which found a variant in the CHEK2 gene. This gene has been linked to an increased risk of prostate cancer and breast cancer (more so in women but a slight increase also for men). It’s an inherited gene from one parent, unfortunately my mother died from cancer 18 years ago and so my father is the only one that can now be tested. We’re just awaiting his results, he was also diagnosed with prostate cancer 11 years ago and so it’s not obvious which side of the family this has come from. My sister has also agreed to be tested, if she is also a carrier then she will be entitled to more regular cancer screening. I have two young boys who will now be entitled to testing when they become adults. 

Best wishes 


Jamie
