Background: Our study aimed to correlate ERG and PTEN expressions in prostate biopsy with multiparametric magnetic resonance imaging PI-RADS score, clinical reclassification, and prognosis of very low-risk prostate cancer (PCa) patients under active surveillance (AS).

Methods: We evaluated 101 very low-risk PCa patients under AS between 2013 and 2018. They were followed with DRE, PSA, MRI, and re-biopsies every 1-2 years.

Purpose: High-risk localized prostate cancer (HRLPC) commonly progresses to metastatic disease after local treatment. Neoadjuvant androgen deprivation therapy (nADT) before radical prostatectomy (RP) has recently been suggested to improve early oncological outcomes in HRLPC. We aimed to perform an exploratory analysis of the pathological outcomes from a prospective trial testing nADT before RP.

Purpose: Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized setting.

Materials And Methods: In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1).

Several phase II trials have investigated neoadjuvant novel androgen receptor signaling inhibitors (ARSIs) in combination with androgen deprivation therapy (ADT) followed by radical prostatectomy (RP) in prostate cancer (PC) patients. However, data regarding complications of intense hormone therapy and surgical complications are scarce. Our objective was to evaluate the occurrence of cardiovascular (CV) and thromboembolic (TE) adverse events (AE) in patients with localized PC who have received intense neoadjuvant ADT followed by prostatectomy.

Robotic assisted radical cystectomy (RARC) is a standard option for the treatment of bladder cancer. Currently, novel platforms are entering the market and the Hugo RAS (Medtronic, Minneapolis, MN, USA) is a new system consisting of an open console with 3D-HD screen and a multi-modular fashion. Even if several series are already available for radical prostatectomy, to now a full description of RARC performed with Hugo RAS is still lacking.

Introduction: Recent studies about intense neoadjuvant therapy followed by Radical Prostatectomy (RP) lack standardized criteria regarding surgical complications and comparison to a group of patients who underwent RP without the use of neoadjuvant therapy. The aim of this study is to describe and compare the perioperative complication rates.

Materials And Methods: This was a prospective, single-center phase II trial in patients with high-risk prostate cancer (HRPCa).

Penile cancer (PeC) is a rare disease, and no prognostic biomarkers have been adopted in clinical practice yet. The objective of the present study was to identify differentially expressed miRNAs (DEmiRs) and genes (DEGs) as potential biomarkers for lymph node metastasis and other prognostic factors in PeC. Tumor samples were prospectively obtained from 24 patients with squamous cell carcinoma of the penis.

Purpose: Partial nephrectomy is the standard treatment for renal tumors <7 cm, and the trend toward minimally invasive surgery has increased. However, data that could support its use and benefits are still lacking.

Materials And Methods: We conducted a prospective, randomized controlled trial comparing surgical, functional and oncologic outcomes in patients undergoing open partial nephrectomy (OPN) or laparoscopic partial nephrectomy (LPN).

Background: To evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy.

Material And Methods: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count.

Immunotherapy has recently been incorporated into the treatment guidelines for metastatic urothelial carcinoma. Nevertheless, the role of prognostic and predictive biomarkers in this setting is not completely defined. To date, PD-L1 expression and a high tumour mutational burden (TMB) seem to predict better responses to immune checkpoint inhibitors, but patients without these biomarkers may still respond to immunotherapy.

Clear cell renal cell carcinoma (ccRCC) has been considered a metabolic disease, with loss of von Hippel-Lindau (VHL) gene and consequent overexpression of hypoxia-inducible factor 1 alpha (HIF-1α), which is central for tumor development and progression. Among other effects, HIF-1α is involved in the metabolic reprogramming of cancer cells towards the Warburg effect involved in tumor cell proliferation, migration and survival. In this context, several proteins are expressed by cancer cells, including glucose and lactate transporters as well as different pH regulators.

Penile cancer (PeC) carcinogenesis is not fully understood, and no biomarkers are reported in clinical practice. We aimed to investigate molecular signatures based on miRNA and mRNA and perform an integrative analysis to identify molecular drivers and pathways for PeC development. Affymetrix miRNA microarray was used to identify differentially expressed miRNAs (DEmiRs) comparing 11 tumoral tissues (TT) paired with non-neoplastic tissues (NNT) with further validation in an independent cohort ( = 13).

Both robotic surgery and head-down tilt increase intracranial pressure by impairing venous blood outflow. Prostatectomy is commonly performed in elderly patients, who are more likely to develop postoperative cognitive disorders. Therefore, increased intracranial pressure could play an essential role in cognitive decline after surgery.

Background: Platinum-based neoadjuvant chemotherapy (NAC) in muscle-invasive urothelial bladder cancer (MIBC) has been adopted as a standard of care related to better survival outcomes. However, there is a considerable number of patients who do not respond, experiencing toxicity and delay in the surgical treatment. Our aim is to find biomarkers of response that could be easily adopted in the clinical practice.

Purpose: A group of international urology and medical oncology experts developed and completed a survey on prostate cancer (PCa) in developing countries. The results are reviewed and summarized, and recommendations on consensus statements for very low-, low-, and intermediate-risk PCa focused on developing countries were developed.

Methods: A panel of experts developed more than 300 survey questions of which 66 questions concern the principal areas of interest of this paper: very low, low, and intermediate risk of PCa in developing countries.

Prostate cancer is currently the second leading cause of cancer deaths in Brazilian men. In 2020, sixty-five thousand new prostate cancer cases were expected in Brazil, and almost 30% of these patients are estimated to be from the northeast region. However, from 75 robotic platforms available in the country, only one is accessible in the state of Ceará since 2015.

Background: Prostate cancer is one of the most prevalent neoplasms in male patients, and surgery is the main treatment. Opioids can have immune modulating effects, but their relation to cancer recurrence is unclear. We evaluated whether opioids used during prostatectomy can affect biochemical recurrence-free survival.

Objectives: To assess the efficacy and safety of single-dose tranexamic acid on the blood transfusion rate and outcomes of patients with complex kidney stones undergoing percutaneous nephrolithotomy (PCNL).

Patients And Methods: In a randomised, double-blinded, placebo-controlled trial, 192 patients with complex kidney stone (Guy's Stone Scores III-IV) were prospectively enrolled and randomised (1:1 ratio) to receive either one dose of tranexamic acid (1 g) or a placebo at the time of anaesthetic induction for PCNL. The primary outcome measure was the occurrence rate of perioperative blood transfusion.
