No association was found between PSMA-11 or FDG uptake and the PSA level in lymph node metastases of patients evaluated preoperatively (Pearson correlation coefficient between PSMA-11 or FDG uptake and the PSA level: r = 0.251, P = 0.085 and r = 0.137, P = 0.564, respectively) or following BCR (between PSMA-11 or FDG uptake and the PSA level: r = 0.042, P = 0.831 and r = 0.215, P = 0.273, respectively). The gene discussed is BCR; the disease is metastatic malignant neoplasm in the lymph nodes.
