Clinical Characteristics of Patients Examined with [68 Ga]Ga-PSMA-11 PET/CT From the 136 study sufferers examined with 68 Ga-PSMA, the clinical and pathological traits are summarized in Table 2. At the time on the 68 Ga-PSMA scan, the median PSA was three.2 ng/mL and range was 0.170 ng/mL. Eighty-two 68 Ga-PSMA individuals had a GS of 7, whereas six sufferers had a GS six. Twenty-seven 68 Ga-PSMA sufferers had a GS of eight and 21 individuals had a GS eight. Most 68 Ga-PSMA individuals have been mostly treated with RP (Ga-RP) (92) (Table 2), 89 of whom had a BCR by definition [5].Table 2.

A multivariable evaluation showed that there was no considerable distinction (p = 0.356) among the two varieties of PSMA scan (18 F-PSMA and 68 Ga-PSMA). 3.3. [18 F]PSMA-1007 PET/CT: Overall Positivity Rate revealed a positivity price of 87.five (112/128 patients) (mean PSA 7.04 18.56 ng/mL). The pre-scan PSA levels differed drastically involving the patients with 18 F-PSMA-positive and 18 F-PSMA-negative scans (p 0.001). Imply as well as median PSA values of sufferers with positive scans have been considerably higher than these with unfavorable scan benefits (mean PSA: 7.98 19.70 vs. 0.43 0.30 ng/mL, median PSA: 1.94 vs. 0.39 ng/mL, p 0.001) (Table three).Table 3.

Between patients with 68 Ga-PSMA-positive scans and those with 68 Ga-PSMA-negative scans, no statistical significance was shown for the differentiation of mean and median PSA (p = 0.068) (mean PSA levels of 11.2 25.7 vs. four.0 5.7 ng/mL, median PSA: three.7 vs. 1.4 ng/mL, p = 0.068) (Table four).Cancers 2022, 14,6 ofTable 4.
