- Surgical method influences specimen margins and biochemical recurrence during radical prostatectomy for high-risk prostate cancer: a systematic review and meta-analysis(2017) SROUGI, Victor; BESSA JR., Jose; BAGHDADI, Mohammed; NUNES-SILVA, Igor; COSTA, Jose Batista da; GARCIA-BARRERAS, Silvia; BARRET, Eric; ROZET, Francois; GALIANO, Marc; SANCHEZ-SALAS, Rafael; CATHELINEAU, XavierPurpose To perform a meta-analysis comparing the rates of positive surgical margins (PSM) and biochemical recurrence (BCR) between open radical prostatectomy (ORP) and robot-assisted radical prostatectomy (RARP) in patients with high-risk prostate cancer. Methods A systematic review was performed on Pubmed, Embase and Scopus databases in August 2016, according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. References retrieved were evaluated using the Newcastle-Ottawa scale and the Black and Down's tool for quality assessment. Results Nine retrospective cohorts comparing ORP and RARP were selected and included in the meta-analysis. All studies reported the PSMs. Patients treated with RARP presented less risk of PSMs (risk difference -0.04, p 0.02) than those treated with ORP. Five articles reported hazard ratios for BCR-free survival. Patients treated with RARP had less risk of BCR (HR 0.72, 95% CI 0.58-0.89) than those treated with ORP. Reports for PSM assessment were considered of adequate quality, while the studies retrieved for BCR assessment were considered limited because of the heterogeneity of their results. Conclusion Patients with high-risk prostate cancer treated with RARP have less risk of having PSM and BCR when compared to those treated with ORP. A strong conclusion is precluded due to the observational nature of the studies retrieved for our analysis.
- Pyeloplasty in Adults With Ureteropelvic Junction Obstruction in Poorly Functioning Kidneys: A Systematic Review(2021) FREITAS, Pedro. F. S.; BARBOSA, Joao. A. B. A.; ANDRADE, Hiury S.; ARAP, Marco A.; MITRE, Anuar I.; NAHAS, William C.; SROUGI, Miguel; DUARTE, Ricardo J.; SROUGI, VictorOBJECTIVES To systematically summarize the available evidence concerning the impact of pyeloplasty on symptoms and differential renal function (DRF) in adults with unilateral UPJO in poorly functioning kidneys (PFK), and to identify potential predictors of kidney function recovery that could help clinicians select candidates for pyeloplasty. METHODS A literature search (MEDLINE, Embase, Google Scholar, Scopus, ClinicalTrials.gov, and the WHO Clinical Trials Registry) and systematic review were performed up to September 2020 according to the PRISMA guidelines. PFK were defined as a baseline DRF =30% on renal scintigraphy. The primary endpoints were symptom relief and postoperative scintigraphic DRF. Predictors of kidney function recovery were evaluated and compared among studies. RESULTS Nine studies comprising 731 patients met the inclusion criteria and were included for evidence synthesis. A DRF increase >5% occurred in 13.3%-53.8% of 160 patients with a pre- and postoperative renal scan. Symptoms improved in 73.3%-93.3% of 141 adults after pyeloplasty. Neither patient's age, baseline DFR, comorbidities, degree of hydronephrosis, kidney parenchymal thickness, nor kidney biopsy findings consistently predicted a significant DRF increase among 375 patients undergoing pyeloplasty. CONCLUSION Based on a low level of evidence, pyeloplasty may relieve symptoms and stabilize kidney function in adults with UPJO in PFK. A significant number of patients showed a DRF increase >5%, yet no consistent predictor of kidney function recovery was identified. Until more evidence becomes available, pyeloplasty could be considered for selected cases after accounting for the risks of a failure requiring a future nephrectomy. (C) 2021 Elsevier Inc.
- Biochemical recurrence after radical prostatectomy: what does it mean?(2018) TOURINHO-BARBOSA, Rafael; SROUGI, Victor; NUNES-SILVA, Igor; BAGHDADI, Mohammed; REMBEYO, Gregory; EIFFEL, Sophie S.; BARRET, Eric; ROZET, Francois; GALIANO, Marc; CATHELINEAU, Xavier; SANCHEZ-SALAS, RafaelBackground: Radical prostatectomy (RP) has been used as the main primary treatment for prostate cancer (PCa) for many years with excellent oncologic results. However, approximately 20-40% of those patients has failed to RP and presented biochemical recurrence (BCR). Prostatic specific antigen (PSA) has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment. The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality (CSM). Review design: A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Objective: To provide an updated assessment of BCR definition, its meaning, PCa natural history after BCR and the weight of each clinical/pathological feature and risk group classifications in BCR, metastatic disease and CSM.
- Getting ready for the first robotic prostatectomy, from basics to real practice(2017) WAGNER, Christian; SROUGI, Victor; SANCHEZ-SALAS, RafaelPurpose of review Robot-assisted radical prostatectomy (RARP) has been embraced by urologists and has become a treatment standard in many countries already. Learning how to perform a RARP is challenging and has not yet been standardized. The current review summarizes the latest concepts regarding the most effective way of training for RARP. Recent findings The strategy to learn RARP should comprise didactic activities, skills lab training, participating in surgeries and mentorship. Skills lab and virtual simulators are valuable tools to develop manual abilities and to overcome the initial technical learning curve. Participating in surgeries is crucial for familiarization with the robot installation, steps of the surgical procedure and is essential for troubleshooting. Mentorship improves learning and is the safest way to initiate real practice. Innate and individual background variances were suggested to influence the learning process; however, there is paucity of robust evidence correlating previous surgical experience and, for example videogame playing with faster learning of RARP. Structured curricula were proposed to orient the training for robotic surgery; currently, only one is focused exclusively on urology. Summary Systematic training is the most effective way to learn and surpass the possibly intense learning curve of RARP. Training activities should focus on developing cognitive and manual abilities. The existing curricula for robotic surgery training still require constant refinement; however, they offer good and structured guidance to train for RARP.
- The Role of Robot-Assisted Radical Prostatectomy in High-Risk Prostate Cancer(2017) SROUGI, Victor; TOURINHO-BARBOSA, Rafael R.; NUNES-SILVA, Igor; BAGHDADI, Mohammed; GARCIA-BARRERAS, Silvia; REMBEYO, Gregory; EIFFEL, Sophie S.; BARRET, Eric; ROZET, Francois; GALIANO, Marc; SANCHEZ-SALAS, Rafael; CATHELINEAU, XavierProstate cancer (PCa) is stratified into different risk categories based on the patient's prognosis. High-risk disease was formerly characterized by an increased risk of metastasis and lethality, requiring complex treatments. Surgery was recently highlighted to have a pivotal role for the treatment of such cases, even as monotherapy. In the past, open radical prostatectomy was performed for most patients with high-risk PCa; however, robot-assisted radical prostatectomy (RARP) emerged as a reasonable option because it provided optimal outcomes for low- and intermediate-risk PCa. Robust studies are lacking to properly assess the role of RARP for high-risk PCa. We summarize this knowledge and present a literature review on the perioperative recovery and functional and oncologic outcomes of RARP for the treatment of patients with high-risk PCa.
