Oncologic Outcomes of Incidental Versus Biopsy-diagnosed Grade Group 1 Prostate Cancer: A Multi-institutional Study.

Background And Objective: Patients diagnosed with grade group (GG) 1 prostate cancer (PCa) following treatment for benign disease ("incidental" PCa) are typically managed with active surveillance (AS). It is not known how their outcomes compare with those observed in patients diagnosed with GG1 on biopsy. We aimed at determining whether long-term oncologic outcomes of AS for patients with GG1 PCa differ according to the type of diagnosis: incidental versus biopsy detected.

Medium-term follow up of active surveillance for early prostate cancer at a non-academic institution.

Objectives: To report oncological outcomes of active surveillance (AS) at a single non-academic institution adopting the standardised Prostate Cancer Research International Active Surveillance (PRIAS) protocol.

Patients And Methods: Competing risk analyses estimated the incidence of overall mortality, metastases, conversion to treatment, and grade reclassification. The incidence of reclassification and adverse pathological findings at radical prostatectomy were compared between patients fulfilling all PRIAS inclusion criteria vs those not fulfilling at least one.

Impact of Trifecta definition on rates and predictors of "successful" robotic partial nephrectomy for localized renal masses: results from the Surface-Intermediate-Base Margin Score International Consortium.

Background: Over the years, five different Trifecta score definitions have been proposed to optimize the framing of "success" in partial nephrectomy (PN) field. However, such classifications rely on different metrics. The aim of the present study was to explore how the success rate of robotic PN, as well as its drivers, vary according to the currently available definitions of Trifecta.

Oncological outcomes of concomitant carcinoma in situ at radical cystectomy in pure urothelial bladder cancer and in histological variants.

Introduction: The presence of carcinoma in situ at transurethral resection is known to increase the risk of recurrence and progression to invasive disease. However, the evidence regarding the prognostic role of concomitant carcinoma in situ after radical cystectomy due to bladder cancer is controversial. Moreover, concomitant carcinoma in situ was found to be significantly associated with bladder histological variants.

Recurrent retroperitoneal solitary fibrous tumor: a case report.

Background: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm described initially in visceral pleura but can occasionally involve other sites such as the urinary tract. Extrapleural localizations are often indolent but some malignant SFTs have been described. The treatment and the most important prognostic factor for SFT seem to be complete resection of the neoplasm.

Increased Use of Blood Transfusions to Manage Urological Conditions during the COVID-19 Pandemic.

A Snapshot from the Department of Urology in Bergamo Evaluating the Timeline of the SARS-CoV-2 Outbreak: Which Patients Are We Missing?

The province of Bergamo in Italy and in particular Papa Giovanni XXIII Hospital was one of the first areas to be hit by the SARS-CoV-2 outbreak and experience firsthand all the different phases of the crisis. We describe the timeline of the changes in overall urological workload during the outbreak period from lockdown to the slow reopening of activities. We sought to compare the 2020 hospital scenario with normality in the same period in 2019, highlighting the rationale behind decision-making when guidelines were not yet available.

Materials And Methods: We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs.

PTRF independently predicts progression and survival in multiracial upper tract urothelial carcinoma following radical nephroureterectomy.

Objectives: Polymerase I and transcript release factor (PTRF) has been implicated in cancer biology but its role in upper tract urothelial carcinoma (UTUC) is unknown. From a pilot transcriptome, we identified PTRF was significantly upregulated in high stage UTUC. Bladder cancer transcriptome from The Cancer Genome Atlas (TCGA) supported our finding and high PTRF level also predicted poor survival.
