Filter by:To evaluate the efficacy and safety of a pembrolizumab therapy of pembrolizumab in combination with standard salvage radiation therapy (SRT) in patients with biochemical recurrence (BCR) of prostate-specific antigen (PSA) persistence after radical prostatectomy (RP).
This study is a single-arm, open-label, single-center study to assess the safety of tislelizumab with BCG, and to obtain the preliminary efficacy results in subjects who have been diagnosed with high-risk NMIBC without prior BCG treatment.
This study will be done to investigate perioperative lidocaine infusion on neutrophil extracellular trapping in the patients undergoing the robot-assisted prostatectomy.
Cancer patients have an increased risk of perioperative complications undergoing surgery procedures. Postoperative complications caused by thrombembolic events after robot- assisted surgery in major urological procedures have been reported and associated with an increased lenght of stay in the hospital. We therefore aimed to investigate in a retrospective analysis 250 patients undergoing robotic-assisted radical cystectomy and prostatectomy procedures for risk factors for thrombembolic events in this specific patient population.
This phase I trial investigates the safety of testosterone replacement therapy around the time of major urologic surgery (perioperative) in order to improve quality of life and post-operative outcomes such as decreased length of hospital stay, complications, and mortality in patients with low testosterone levels. Studies have demonstrated that patients undergoing testosterone replacement therapy have increased lean body mass, decreased fat mass and have improved physical function. Testosterone replacement therapy can also stimulate bone formation and may decrease the risk of fracture. Information from this trial may be used to support the incorporation of testosterone level testing and testosterone replacement into the perioperative treatment decision-making process.
The study described here is being conducted to prospectively confirm the performance of the ExoDx Prostate gene expression assay in patients presenting for an initial prostate biopsy and support of CE-marking the test for a European Union Launch.
To facilitate the follow-up of urothelial tumors and also make them more tolerable and less invasive for patients, there is a minimally invasive and easy to perform examination which is urinary cytology on 3 samples. This test is extremely specific, over 90% chance of cancer if it is positive and is performed by expert cytopathologists, but it is burdened by a very low sensitivity, which is especially acute in the case of low grade tumors. This makes it an extremely useful test in case of positivity, but of little use if negative or doubtful, not being able to consider it reliable. To overcome this problem, our study aims to bring an approach based on a physical principle, that is spectroscopy, which is fast non-invasive and does not require the use of additional substances or contrast media in the diagnosis of urothelial neoplasms in samples of urine. In our experience, multimodal optical fiber spectroscopy has proved extremely valid in discriminating healthy urothelial tissue from tumor ex vivo, as well as providing important information on the degree of urothelial neoplasia, with accuracy rates higher than 80%, for which developed the idea of a technique based on multimodal spectroscopy. If our method proves valid, it could improve the follow up and management of patients with urothelial cancer, being able to support normal cytology and provide further support to the cytopathologist, as well as simplify the diagnosis.
Background: Upper tract urothelial carcinoma (UTUC) is a rare tumor associated with bladder cancer in up to 50% of cases. Its incidence is rising due to improved detection and bladder cancer survival. The diagnosis of UTUC is challenging because more than 35% of the standard biopsies can result inconclusive. The grading of UTUC cells, which delivers the most important data for the choice between a kidney-sparing surgery (KSS) and a radical treatment, is upgraded in 30% of radical nephroureterectomies. The follow-up of UTUC after KSS requires an invasive procedure as a diagnostic ureteroscopy for a minimum of 5 years, and urinary cytology has low diagnostic power. Objective: The aim of the study is to evaluate the accuracy (overall and stratified for grade) of a DNA methylation urine biomarker test (Bladder EpiCheckTM) in UTUC, and to compare it with current standard (urinary cytology). The secondary objective is to show its applicability in the specific clinical scenario of UTUC surveillance after kidney-sparing surgery and related cost-effectiveness. Design, Setting, and Participants: From February 2019 to February 2021, 80 consecutive patients candidates to ureteroscopy for suspicion of primary, recurrent or metachronous UTUC in one tertiary Referral Centers (Fundaciò Puigvert) giving written informed consent will be included in the study. Intervention: Bladder urine samples (> 10 ml) will be collected for cytology and for the methylation test before cystoscopy. Prior to semirigid and flexible ureteroscopy, urine specimens from the upper urinary tract will be obtained via a ureteral catheter.
Ureteral double- J stent is usually inserted by retrograde approach for the treatment of obstructed upper urinary tract. The antegrade approach, can a suitable alternative in certain situations without the need for general or spinal anesthesia. The present study demonstrates the indications, success rate, and complications of this approach in the treatment of malignant obstructive uropathy.
The purpose of the open-label INDIGO-study is to examine whether a first line individualized treatment strategy based on DNA and RNA analyses from the patient's tumor is feasible. Moreover, to involve the patient further in their treatment via patient-reported outcomes (PRO) measurements in a value-based healthcare setup with simultaneous analyses of the financial costs of this strategy. The patients are assigned into 4 treatment arms according to the results of their DNA and RNA analyses. All patients receive electronic questionnaires regarding symptoms and side effects weekly and questionnaires regarding quality of life monthly. Based on each patient's answers of the questionnaires the patient receives advices in the app to reduce the symptoms and side effects or the patient is instructed to contact the hospital. The hypothesis: Basing the choice of first-line treatment for DNA mutations and RNA profiles in a heterogeneous patient population increases the overall response rate for the total population to 30% compared to 10% for historical cohorts.
