PSMA uptake in lymph node metastases was significantly higher than in ganglia for any location, cervical, coeliac, and sacral locations (any location:19.3 ± 19.0 vs. 2.2 ± 0.7, P < 0.001; cervical: 10.7 ± 6.6 vs. 2.4 ± 0.6 0.7, P < 0.001; coeliac: 15.1 ± 12.4 vs. 2.4 ± 0.8, P < 0.001; sacral: 21.9 ± 20.3 vs. 1.8 ± 0.4, P < 0.001) (Figure 4A). This evidence concerns the gene FOLH1 and metastatic malignant neoplasm in the lymph nodes.
