Welcome to the Forum! Here is a review of the protocols for some of the major AS programs, including candidacy and conversion to treatment.
Active surveillance for prostate cancer: a systematic review of contemporary worldwide practices (2018, Review)
No, you are not an ideal AS candidate. The problem with numerous G6 cores on biopsy is that the chances increase that there are lesions of a higher Gleason grade that were missed. In fact, your number of G6 cores would be enough that you would have to
leave the stricter AS programs for treatment! The only suggestion I would have if you are truly considering AS is to have a genomics test, like Decipher Biopsy or OncotypeDx to rule out that you are high-risk for developing more serious lesions that may metastasize (about
10% of G6 men are in the high-risk category *IF* their cancer is prostate-confined -- something that imaging can suggest, but not guarantee). G6 itself cannot metastasize, but it can grow out from the prostate locally.
You have time to reach a treatment decision -- don't be hasty! Evaluate all your options. *IF* you choose surgery, know that your choice of a very experienced surgery is the most important thing you can do to ensure the best possible outcome for your status!
