Circulating tumor cell (CTC) status at any time point correlates with previously recognized patterns of disease recurrence of the clinicopathologic risk factor, margin status. (a) Percentage of patients with CTCs absent (CTC^neg/-; n=29) at all time points versus CTCs present (CTC^pos/+; n=9) at any time point who presented with extracapsular extension. (b) Percentage of patients with CTC^neg (n=25) at all time points versus CTC^pos (n=6) at any time point who presented with positive margins. (c) Percentage of patients with CTC^neg (n=4) at all time points versus CTC^pos (n=4) at any time point who presented with seminal vesicle invasion. (d) Percentage of patients with CTC^neg (n=3) at all time points versus CTC^pos (n=1) at any time point who presented with a Gleason score of >7.
