Evaluation of PSMA Expression in Triple Negative Breast Cancer Patients Using 18 F-DCFPyL-PET/CT
Ahmad Shariftabrizi
Summary
The purpose of this research is to determine the expression of Prostate Specific Membrane Antigen(PSMA) in metastatic Triple Negative Breast Cancer (TNBC) patients using Fludeoxyglucose F18 (FDG) PET/CT as the gold standard. The investigators hypothesize that most lesions in metastatic TNBC are PSMA-avid; and thus PSMA-based radionuclide therapy can be a valid treatment option for TNBC, and clinical trials can be designed for this purpose. Thirty metastatic TNBC patients will be enrolled and will be on the study for maximum of 4 weeks.
Description
Prostate Specific Membrane Antigen (PSMA) is not only expressed in prostate cancer and its metastases, but also it is expressed on the neovasculature of many other solid tumors including gastric, lung, adrenal, bladder and renal cell carcinomas. Also, there is evidence that breast carcinomas express PSMA, although this has not been specifically studied in the metastatic TNBC. The study involves a total of 2 visits and on each visit, patients will undergo a PET imaging. Each patient will first undergo an (FDG) PET/CT and then in few days will undergo an 18F-DCFPyL-PET/CT. The PET scanner is a…
