@geneva26 Prolaris is specifically targeted for decisions for 3+4 to continue active surveillance or go to treatment. If you had this test before radiation, it was probably used in the recommendation for treatment. The Decipher test is the one that is used to predict probability of recurrence. Probably some overlap. In any case you should be having PSA tests every 3 months for the first year or 2 after ADT ends, than every 6 months to catch any recurrence early.
