ECE means the disease is no longer confined to the capsule (prostate) but it does not mean it is no longer curable. Sticking your head out the window doesn't mean you have left the house yet.
I found out that I had ECE in my pathology report AFTER my surgery. So far, almost 2 years later, I am not showing any recurrence of the cancer.
I would suggest you talk to your doctor to ask him what it means to YOU!
