Filter by:This is a phase II, multicenter, randomized open-label and comparative trial designed to study the effectiveness and the safety of androgen receptor antagonist (darolutamide) combined with surgery in patients with high-risk and/or locally advanced prostate cancer. In this trial, patients will be assigned in one of the two following treatments arms: - Arm A (control arm): Surgery alone (radical prostatectomy with lymph node dissection) - Arm B (experimental arm): Peri-operative darolutamide + surgery (radical prostatectomy with lymph node dissection) A total of 240 patients will have to be randomized with 120 patients in the control arm and 120 patients in the experimental arm.
Trans-perineal focal laser ablation represents a promising alternative focal therapy option for patients with low-risk or favorable intermediate risk prostate cancer. FLA has been extensively utilized for over a decade in the treatment of PCa using different anatomical approaches. The proposed study differs from past ones in that a trans-perineal approach with reduced risk of infection will be used in contrast to the current trans-rectal approach. In addition, high frequency micro-ultrasound imaging will be used to enhance imaging and facilitate accurate needle placement and FLA of the index lesions. The aim of this study is to evaluate FLA as a potential optimal therapeutic intervention based on safety, ease of use, efficacy, and cost.1 FLA holds promise for the management of localized tumors. The combination of the trans-perineal focal laser ablation and micro-ultrasound imaging will enable targeted trans-perineal fusion laser induced thermal therapy of prostate cancer lesions. This approach offers significant potential advantages over traditional interventions including: - Improved dynamic ultrasound imaging of the lesion to be treated compared to traditional ultrasound techniques. - Enhanced ability to visualize and spare critical structures within the prostate, including the bladder neck, neurovascular bundle (NVB), urethral sphincter and organs in close proximity including the rectum. - Sparing these structures should translate into improved preservation of ejaculation, limited changes in sexual function and minimal transient incontinence following treatment.
This is a single center prospective non-randomized controlled study. The goal of this clinical trial is to figure out whether the combination of PSMA-PET/MR and PHI could add values to each method alone. The main questions it aims to answer are: - Compare the diagnostic value of the combination with each alone and set up a diagnostic model. - Compare the diagnostic value of PSMA-PET/MR+PHI to mpMRI+PHI. - Evaluate the diagnostic value the combination of PHI and PSMA-PET/MR in suspected PCA patients. Patients will experience mpMRI or PSMA-PET/MR and their blood samples will be used to test PSA and p2PSA. Prostate biopsy will be the golden standard.
Androgen Deprivation Therapy (ADT) is associated with cognitive impairment and dementia in men with prostate cancer. Pre-clinical data suggest that ADT-induced hypogonadism leads to accumulation of beta-amyloid plaques in the hippocampus, a pathological hallmark of Alzheimer's Disease (AD). Neuroimaging Functional magnetic resonance imaging (fMRI) studies also demonstrate that ADT decreases metabolic activity in the parietal, occipital, and prefrontal cortices. Multiple prospective cohort and population-based clinical studies have been conducted to test the association between ADT and cognitive impairment and/or dementia. Plasma biomarkers have been developed to predict brain amyloidosis, a key pathological feature of AD and a risk factor for developing dementia due to AD. The advantage of a blood-based assay is the lower cost, invasiveness, and time compared to cerebrospinal fluid (CSF) and Positron Emission Tomography (PET)-based biomarkers.
Randomized Phase III study, comparing pelvic ultra-hypo fractionated radiotherapy (UHF: 5Gy/fraction) to a standard or moderate hypo-fractionation (1.8-2.15Gy/fraction), both associated to an HDR prostate +/- adjacent seminal vesicles brachytherapy boost (HDR-BT)+ ADT according to NCCN guidelines. Considering that the calculated bio-equivalent doses to the tumor are similar for all treatment options, the UHF technique is deemed to be non-inferior to the standard approach. Treatment acceptability, tolerance and adverse events will be reported and compared for non-inferiority as the primary objective. Secondary objectives are biochemical control, metastasis-free, disease specific and overall survival.
The objective of this pilot cohort study is to investigate associations between CIN and changes in gut microbiome composition profiles.
The goal of this prospective observational study is to evaluate the diagnostic precision of the Biparametric Magnetic Resonance Imaging (bpMRI) in the detection of clinically significant prostate cancer (PCa) in patients with biochemical suspicion of prostate cancer with PSA (Prostate Specific Antigen) > 4 ng/mL and a normal digital rectal examination and without a biopsy previous to the MRI. Secondary aims are: - Determine the validity as a diagnostic test of the first directed transrectal prostatic biopsy (cognitive fusion) versus systematic biopsy of 12 cylinders in patients with suspicious lesions in the bpMRI. - Develop a predictive nomogram that permits the reduction of the number of prostatic biopsies performed to patients with a low suspicion of prostate cancer in the bpMRI.
This is a single arm study to evaluate the safety and biodistribution of 177Lu-labeled NY108 (177Lu-NY108) SPECT Imaging in patients.
The Active Surveillance study is a prospective study developed to look at the association of biomarkers with PrCa presentation and progression among men on Active Surveillance and stratify it by their genetic risk. This study will also investigate the incidence and progression by differing genetic risks.
Minimally-invasive surgery, either laparoscopic or robotic, is commonly used in urology. Several urologic procedures including prostatectomy, radical nephrectomy, and partial nephrectomy are now commonly performed robotically. Patients undergoing these procedures often have delayed return of bowel function and persistent gastrointestinal symptoms including nausea/vomiting, abdominal distension, and bloating for several days to weeks after surgery. Postoperative stool softeners and laxatives are routinely used in an effort to minimize these symptoms, with varying degrees of success. The aim of this study will be to evaluate whether the use of a preoperative osmotic laxative will be beneficial in improving recovery of bowel function and alleviating postoperative gastrointestinal complaints in patients undergoing these procedures. Patients will be randomized to either receive or not receive three days of polyethylene glycol (PEG, also known as MiraLAX) on the three days before surgery. Patients in both groups will receive the same postoperative bowel regimen including scheduled PEG both in the hospital and upon discharge until first bowel movement. Patients will be given a questionnaire and diary to record their postoperative gastrointestinal symptoms and time to first bowel movement. These questionnaires and diaries will then be analyzed to determine differences in time to first bowel movement and gastrointestinal complaints during their recovery from surgery.
