Surgical and Functional Outcomes of Rectourethral Fistulas Surgery With Gracilis Flap Interposition...
Rectourethral FistulaProstate cancer is the first cancer amongst men with more than 50000 cases per year in France. Surgical, radiation, frost, or ultrasound induced rectourethral fistula is a rare complication (<1%) of localized prostatic cancer treatment but hard to manage. Different types of treatment exist: conservatory, trans-sphinteric (York-Masson), transanal, perineal, with or without muscle flap interposition. Gracilis flap interposition for rectourethral fistula management is a promising technique but few cases are described and functional results are scarce. The aim of this study is to present surgical and functional outcomes of rectourethral fistulas surgery with gracilis flap interposition after treatment of localized prostate cancer.
Micro-ultrasound for Prostate Cancer Diagnosis
Prostate CancerThis is a monocentre, paired-cohort, prospective study. Patients with a clinical suspicion of csPCa will receive mpMRI and Micro-US in two different visits. The results of the diagnostic procedures will determine how many and which type prostate biopsies patients will undergo. During the following visit patients with both positive mpMRI and Micro-US, defined as the presence of one or more lesions with PI-RADS ≥ 3 and PRI-MUS ≥ 3 respectively, will receive a 12-core TRUSBx in addiction to MRI-TBx and Micro-US-TBx (Group 4). Patients with both negative mpMRI and Micro-US will receive a 12-core TRUSBx (Group 1). Patients with only postitive mpMRI will receive MRI-TBx and 12-core TRUSBx (Group 2). Patients with only positive Micro-US-TBx will receive Micro-US-TBx and 12-core TRUSBx (Group 3). Our hypothesis is that the sensitivity for csPCa (defined as prostate cancer with Gleason score ≥ 3+4) of Micro-US will be superior or at least equal to that of mpMRI. Despite the introduction of the mpMRI and MRI-TBx has improved the diagnostic pathway of PCa, the proportion of men with negative mpMRI with a csPCa is still difficult to delineate due to the high variability of mpMRI negative predictive value (NPV) and specificity. In this context, a specific standardization of the use of Micro-US may play a crucial role to optimize PCa diagnostic pathway. Moreover, a direct comparison between Micro-US and mpMRI might be useful to determinate whether Micro-US could be more accurate than mpMRI for PCa diagnosis. Furthermore, in patients with suspicion of PCa the combined use between mpMRI and Micro-US might increase the detection of csPCa and reduce the number of unnecessary biopsies, improving mpMRI limitations in NPV and specificity. Demonstrating that Micro-US provides a similar sensitivity for csPCa as compared to mpMRI may lead to its definitive inclusion in daily clinical practice, potentially replacing mpMRI, streamlining the current diagnostic pathway of PCa.

Prostate Cancer Screening Among Men With High Risk Genetic Predisposition
BRCA1 SyndromeBRCA2 Syndrome1 moreThis will be a prospective diagnostic trial of screening for prostate cancer among men with genetic predisposition.
Magnetic Resonance Spectroscopic Imaging Study of Prostatic Fats to Distinguish the Difference Between...
Prostate CancerA prostate cancer diagnosis starts a list of events that often leads to fast-moving treatment, thought by many to result in vast over-treatment of this disease. So, discovery of different diagnostic methods that allow clinicians to identify slow-growing from potentially fast-growing disease prior to or at the time of prostate biopsy could result in early and suitable treatment for men at greatest risk, while greatly decreasing the number of biopsies, surgical procedures, hormonal and chemotherapeutic treatments, cost, and patient worry, for those with more slow-growing disease.
Impact of the Geographical FACTor on the Prostate Cancer Stage at Hormonal Therapy Initiation
Prostate CancerFrench epidemiological data have shown a heterogeneous distribution of the risk of mortality from prostate cancer according to region. The main objective is to describe the distribution of prostate cancer stages when first line hormonal therapy is introduced (overall and by region).
Development of Clinical Assessment Technique Using Multi-radiotracer PET/MR in Prostate Cancer
Prostate Cancer RecurrentStage II Prostate Carcinoma1 moreTo development of clinical assessment technique using multi-radiotracer positron emission tomography/magnetic resonance (PET/MR) in prostate cancer to establish the optimal imaging technique of PET/MR using multiple radioactive tracers for prostate cancer to establish the imaging biomarker using PET/MR for clinical assessment of prostate cancer and early detection of recurrent prostate cancer
Response of Patients on Surveillance for Prostate Cancer to Dutasteride
Prostate CancerHypothesis: That, in men on surveillance for favorable risk prostate cancer treated with dutasteride, prostate specific antigen (PSA) kinetics is of value in identifying those men who harbor occult high grade prostate cancer. The study will determine the prevalence of a secondary rise in PSA > 0.5 ng/ml and the PSA doubling time in subjects on surveillance being treated with dutasteride.
Pilot Study of Secondary Causes of Osteopenia/Osteoporosis in Adults With Breast and Prostate Cancer...
Breast CancerProstate Cancer2 moreThe investigators hypothesis is that secondary causes of bone loss are prevalent in patients with breast and prostate cancer, and those patients with secondary causes of bone loss are at higher risk for treatment related bone loss. The goals of this pilot study are to estimate the prevalence of secondary causes of osteoporosis in a cohort of patients with nonmetastatic breast and prostate cancer with osteopenia and osteoporosis.
