Circulating tumor cell (CTC) status at baseline correlates with previously recognized patterns of disease recurrence of the clinicopathologic risk factors, extracapsular extension, seminal vesicle invasion and margin status. (a) Percentage of patients with CTCs absent (CTC^neg/−; n=34) versus CTCs present (CTC^pos/+; n=4) at baseline who presented with extracapsular extension. (b) Percentage of patients with CTC^neg (n=29) versus CTC^pos (n=2) at baseline who presented with positive margins. (c) Percentage of patients with CTC^neg (n=5) versus CTC^pos (n=3) at baseline who presented with seminal vesicle invasion. (d) Percentage of patients with CTC^neg (n=3) versus CTC^pos (n=1) at baseline who presented with a Gleason score of >7.
