However, the sensitivity and NPV of 68Ga-PSMA-11 PET/CT for LNM detection in our study is significant better than that of the results of Budäus L et al. However, the specificity and PPV of 68Ga-PSMA-11 PET/CT for LNM detection in our study is slightly below that of the results of Budäus L et al. This may due to the limited number of positive lymph nodes, especially the number of micro-metastases or isolated tumor cells (ITC) in our study. This evidence concerns the gene FOLH1 and neoplasm.
