Furthermore, distribution of the PSMA-avid metastases was as follows: bone only in 27.7% (n = 15) of the patients, local recurrence with lymph nodes in 14.8% (n = 8), bone and lymph nodes in 40.7% (n = 22), bone with hepatic and lymph node metastases in 9.5% (n = 5), and bone with pulmonary and lymph node metastases in 7.4% (n = 4) of the patients. Here, FOLH1 is linked to metastatic malignant neoplasm in the lymph nodes.
