The objectives of this pilot feasibility study, which is on the use of 68-Ga PSMA PET imaging of salivary gland tumours, are * to determine the proportion of patients with high PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancer; and * to determine if in vitro PSMA expression correlates to PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancers. The hypotheses of this study are that there is high PSMA-ligand uptake on Ga-68 PSMA imaging in locally advanced, recurrent or metastatic salivary gland cancers and other rare cancers; and that in vitro PSMA expression correlates to PSMA-ligand uptake on Ga-68 PSMA imaging.
