If you looked at the link, I included, it said this

With biochemical recurrence diagnosed at uPSA ≥0.03, the majority (72%) of the high-risk cohort had failed by the median follow-up of 44 months.

72% does not equal 98% but it is not a good percentage to have to face.

Another factor, however, is that that these were high risk patients, Not your normal risk level patients. I wonder what your study really showed.
