PET/CT Detection Rate for Cutoffs Determined by ROC Curve Analysis
| PSAdt cutoff | PSAvel cutoff | |||
|---|---|---|---|---|
| Group | >3.4 mo | ≤3.4 mo | <1.1 ng/mL/y | ≥1.1 ng/mL/y |
| All patients with PSAdt and PSAvel data (n = 106) | 22/72 (31%) | 19/34 (56%) | 5/39 (13%) | 36/67 (54%) |
| Patients with PSAdt and PSAvel data and low trigger PSA (<2 ng/mL) (n = 60) | 8/43 (19%) | 7/17 (41%) | ||
Data are number of patients with positive PET/CT findings divided by total number of patients falling within cutoff range.
