Distribution of pre- and postoperative parameters among study patients

Note that biochemical recurrence with postoperative PSA levels ≥0.4 ng/ml within 64 months was used as a cut point for defining progression. Thus, any CaP patient who showed a biochemical recurrence within 64 months was included in the progressed category. For the progressed group, median time for recurrence was 19 months and mean time for recurrence was 21.3 months. For the nonprogressed group, median follow-up time was 79 months; mean follow-up time was 80.6 months.
