TABLE 2.
PSMA Expression at First PET/CT by Site of Relapse/Metastasis (n = 152)
| Site of relapse/metastasis | No. of patients (n) | Median SUVmax | Min–max SUVmax |
|---|---|---|---|
| Bones | 100 (65.8%) | 24.0 (IQR, 14.3–37.9) | 3.8–127.0 |
| Nodes* | 91 (59.9%) | 16.7 (IQR, 11.0–28.0) | 2.1–138.0 |
| Prostate bed relapse | 32 (21.1%) | 10.1 (IQR, 7.9–19.9) | 3.0–68.0 |
| Visceral | 22 (14.5%) | 17.5 (IQR, 6.0–27.0) | 4.6–45.0 |
*
Pelvic and distant.
IQR = interquartile range; PET/CT = positron emission tomography/computed tomography; PSMA = prostate-specific membrane antigen; SUVmax = maximized standardized uptake value.
