Study Summary

This phase I trial studies the impact of monosodium glutamate (MSG) on 68GA-PSMA-11 PET/CT in decreasing the salivary glands uptake in patients with prostate cancer. Prostate specific membrane antigen (PSMA) is a molecule that is overexpressed by the prostate cancer cells. 68GA-PSMA-11 is an imaging radioactive drug that can target this molecule in tissues for imaging and therapy of prostate cancer. Food substances, such as monosodium glutamate, may reduce salivary gland uptake of 68GA-PSMA-11. Ultimately, giving MSG may reduce potential harm and injury to the salivary glands in patients with prostate cancer treated with PSMA-targeted molecular radiotherapy.

Primary Outcome

Standard uptakes values (SUV) values (maximum SUV \[SUVmax\] and SUVmean) in all assessable salivary glands will be measured with a spherical volume-of-interest with and without the administration of monosodium glutamate (MSG) interventions. SUVmax/salivary gland will be calculated and a mean SUVmax/patient will be generated. The aim is to show a 2-fold reduction of the salivary gland 68Ga-PSMA-11 uptake after MSG administration. Paired T-test will be used to determine statistical significance p
