MKI67 and breast cancer: In both cases, the comparison with [18F]FDG was reported, with the following conclusions: (1) [18F]PSMA-1007 can detect more lesions than [18F]FDG, mainly in the skeleton, whereas brain metastases can be exclusively detected by [18F]PSMA-1007 [56] and (2) [68Ga]Ga-PSMA-11 can be correlated with Clau 4 that is expressed in epithelia and endothelia of cancer cells that are associated with metastasis and poor prognosis in BC patients [57] and with a high ki67 index, thus opening the way for implementing a theranostic approach also in TNBC patients [58].
