Post\u2010RP status was defined as no evidence of disease (NED; never developed detectable PSA), PPP (first PSA remained detectable), and BCR (initially undetectable PSA with PSA \u22650.2 ng\/mL later). The following differences were quantified: (1) pre\u2010RP characteristics, (2) pathologic characteristics at RP, (3) subsequent treatment patterns, and (4) differences in mortality outcomes based on postoperative PSA status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 15,390 patients with who had a follow\u2010up of 4.0 years (interquartile range, 2.4\u20134.6 years), 11,019 still had NED, 1919 had PPP, and 2452 developed BCR. Patients who had PPP demonstrated a higher risk pre\u2010RP and post\u2010RP characteristics compared with those who had NED or BCR on unadjusted and adjusted comparisons, with differences that were both statistically significant and clinically meaningful.
