Filter by:Current research suggests that diets rich in multiple food types (such as broccoli, onions and garlic) are beneficial to our health and may reduce the risk of some cancers, including prostate cancer. The purpose of this study is to investigate the relationship between ingestion of the bioactive compounds from broccoli and garlic, and prostate metabolism.
This study describes how to perform a correct prostatic apex and membranous urethra in order to preserve all anatomical elements that are necessary to achieve a very fast urinary continence after open/laparoscopic/robotic radical prostatectomy, avoiding positive surgical margins at this level.
The study is a prospective randomized controlled trail to compare early urinary continence recovery after robotic-assisted radical prostatectomy with or without sustainable functional urethral reconstruction (SFUR).
This is a multicenter phase 2b study to evaluate the efficacy and tolerability of ModraDoc006 in combination with ritonavir (denoted ModraDoc006/r) in patients with metastatic castration-resistant prostate cancer, suitable for treatment with a taxane.
The presence of circulating tumor cells (CTCs) in the blood of prostate cancer patients has been shown to be an important indicator of metastatic disease and poor prognosis. Additionally, changes in CTC number throughout treatment have been demonstrated to reflect therapy response. However, the CellSearch® (Menarini-Silicon Biosystems) is the only FDA- and Health Canada-cleared CTC platform available at the present time, and is thus considered the current "gold standard" for clinical CTC analysis. Notably, CTCs are undetectable in ~35% of metastatic CRPC patients. This suggests that either CTCs are truly not present in >1/3 of patients with advanced metastatic disease; and/or that CTCs are present but not detectable as they do not meet the standard CellSearch® definition of CTCs. Given the accumulating evidence that prostate cancer cells can lose epithelial characteristics as they evolve towards a more metastatic phenotype, the investigators believe the latter scenario is most likely. The epithelial-to-mesenchymal transition (EMT) is a critical process during embryonic development and cancer metastasis. Although the role of androgen receptor (AR) signaling in EMT is poorly understood, studies have also demonstrated that EMT may be facilitated by androgen deprivation, castration-resistance, and/or disruption of androgen signaling. Importantly, several clinical studies have demonstrated that CTCs with a purely mesenchymal phenotype are undetectable by CellSearch®, but that the presence of mesenchymal marker expression on CTCs with a hybrid epithelial-mesenchymal phenotype is indicative of poor prognosis. In addition, previous pre-clinical data from the Allan laboratory has demonstrated that in animal models, prostate cancers with a mesenchymal phenotype shed greater numbers of CTCs more quickly and with greater metastatic capacity than those with an epithelial phenotype. Notably, the clinically-used CellSearch®-based assay captured the majority of CTCs shed during early-stage disease in vivo, and only after the establishment of metastases were a significant number of undetectable CTCs present. This suggests that current clinical assays may be limiting ability to capitalize on the full potential of CTCs, and that a greater understanding of CTC biology is necessary in order to guide future technology development and translation to the clinic.
This is an open observational extended follow-up study of patients originally randomized into TOOKAD® Soluble VTP therapy or active surveillance (control group). Additional 60-month follow-up study
This prospective registry will evaluate the feasibility and impact of implementing standard cancer family history review and guideline-aligned genetic testing for men diagnosed with Prostate Cancer in community urology practices nationwide.
This is a non-randomized, prospective trial of men who are scheduled for radical prostatectomy for treatment of prostate cancer, or repeat biopsy for localized prostate cancer as standard of care and who will undergo a series of pre-operative multi-modality imaging studies. Post intervention, hybrid imaging maps (HIM) will be generated and the predictions of the HIM (3D location, volume and grade of cancer) will be correlated with actual pathology results to gauge the performance of the HIM in both radical prostatectomy and biopsy settings.
This is a prospective outcomes study assessing quality of life and oncological control at pre-defined time points following FOCAL CRYO-ABLATION (FCA). The investigator's standard of care is to perform an Magentic Resonance Imaging (MRI) and prostate biopsy two years following FCA. The prostate biopsy assesses both the presence of in field and out of field disease. The role of Axumin PET/MRI for detecting disease following FCA has not been previously examined.
Prostate cancer (PCa) is the most common solid organ cancer in North American men. Patients becoming refractory to loco-regional therapy receive androgen deprivation therapy, but their disease will inevitably progress to metastatic castration-resistant prostate cancer (mCRPC). Treatment failure and poor progression-free survival could be explained by the fact that PCa metastases in the same patient may be polyclonal, showing opposite responses to systemic therapies. This project aims to recruit 100 patients with mCRPC in order to determine the prevalence of intrapatient intermetastasis polyclonality and NED using PET/CT triple-tracer PSMA/FDG/OCTREOTATE imaging and eligibility for either PSMA or OCTREOTATE radioligand therapy (RLT).
