How does PTEN loss impact treatment?

I was diagnosed with prostate cancer two weeks ago following an MRI with a PRADS score of 5 and Biopsy with a Gleason Score of 3+4=7. I began discussing a treatment plan based on that information and the fact that the cancer appears to be localized in one area of the prostate. Friday night, I received a call from my doctor. The call was to inform me that the genetic testing of the cancer reveal a total loss of my PTEN(cancer suppression gene) in 75% of the cancer cells. From what I understand, this puts me at a high risk for reoccurance, high risk for spreading outside the prostate and makes it more difficult to treat. Has anyone else had this diagnosis? What are my treatment options now?
