"The long-term rates of undetectable PSA associated with an SRT strategy were 83% and 50% for men with SM+/ECE and SVI, respectively. In the subset of 716 men who did not receive any hormonal therapy, the corresponding long-term rates of undetectable PSA were 91% and 75%, respectively."
91% long term rate of undetectable PSA. That's music to my ears, since I fall into that statistical group (positive margins, no hormonal treatment).
