Post Prostatectomy Clinical Trial
Official title:
Phase II Study: [18F]DCFPyL PET/MRI for Personalizing Prostate Cancer Subclinical Metastatic Ablative MR-guided Radiotherapy (MRgRT)
In the clinical scenario of recurrent prostate cancer (PCa) post local therapy, current standard studies (bone scan and computed tomography) commonly fail to identify the recurrent disease location. In this study the investigator aims to prospectively map recurrent disease with the unique combination of whole-body MR anatomical imaging combined with a new high-sensitivity and PCa-specific PET probe (PSMA-targeted: [18F]DCFPyL) to provide precise localization information to target disseminated tumor deposits in men presenting with rising PSA after prostatectomy and radiotherapy (maximal local therapies). Moreover, we will consequently treat all identified disease with image-guided stereotactic ablative radiotherapy (SABR), which has shown tantalizing results achieving excellent tumor eradication rates with minimal toxicities. This study is uniquely positioned to enable the discovery of new biomarkers and the correlation of prognostic tests (e.g. genomic signatures) from the initial prostatectomy specimen with the PET-MR/CT imaging results and curative-intent treatment outcomes. The significance of the proposed work towards a measurable impact in PCa care is important to emphasize. The study team believes this novel curative-intent approach will transform lives, as opposed to therapies that transiently impact incurable disease stages. Herein, the focus is on patients at the earliest point of the disease spectrum of recurrent PCa after curative-intent treatments. Our hypothesis is that PSMA-targeted [18F]DCFPyL PET-MR/CT allows earlier detection and localization of defined metastatic targets in these patients, at a stage amenable to image-guided curative-intent therapy.
