PSMA PET/CT in diagnostiek en responsevaluatie in patiënten met primair gemetastaseerd prostaatkanker: Een overzicht van de impact op behandelbeslissingen

Abstract

Prostate cancer is one of the most common cancers in man. Adequate staging is important in determining prognosis and guiding therapeutic decisions. The prostate specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) has a higher diagnostic accuracy than conventional imaging, consisting of CT-thorax/abdomen and bone scintigraphy. This ensures better visualization of metastases and therefore changes the stage, usually to a higher stage, of prostate cancer at diagnosis. The impact of this stage shift on oncologic outcomes is unclear, however it hypothetically ensures better outcomes of patients diagnosed at the same stage. It is unclear which impact this stage shift should have on therapeutic decisions. In patients with metastatic prostate cancer PSMA PET/CT findings and treatment response on the PSMA PET/CT could predict the likelihood of successful treatment.
