A recent meta-analysis summarized the value of PSMA PET/CT imaging in guiding lymph node dissection in prostate cancer patients and found that PSMA PET/CT imaging had a high NPV (97%) based on lymph node analysis, and PSMA PET/CT scan had a high NPV (97%), which provided promising accuracy in the field of lymph node staging for PCa. The gene discussed is FOLH1; the disease is prostate cancer.
