Background And Objective: Given the uncertainty regarding the role of radical nephroureterectomy (RNU) as part of a multimodal treatment strategy for upper tract urothelial carcinoma (UTUC) patients with cN+ disease, we aimed to perform a systematic review and meta-analysis of the corresponding literature.

Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 17 observational comparative and noncomparative studies, published between January 2000 and September 2024, evaluating UTUC patients with cTanyN+M0 disease (P) who received RNU as part of a multimodal treatment strategy (I), as compared with any treatment strategy if applicable (C), to assess oncological or postoperative outcomes (O). Meta-analyses were further performed, as appropriate.

The pesticide transportation to deeper soil layers can result in groundwater contamination and, consequently, environmental issues. In this research, our objective was to investigate transport efficiency of indoxacaarb using three different soils to understand the leaching potential. The leaching experiments were performed using a 0.

Although high-level evidence is currently lacking, noninferiority randomised controlled trials in predefined risk groups in non-muscle-invasive bladder cancer are under way to scientifically prove the safety of urinary biomarker-guided follow-up. To facilitate recommendations for clinical use, it is essential to comply with the EU certification for in vitro diagnostics and to demonstrate cost effectiveness.

Introduction: The COVID-19 pandemic disrupted normal pathways to cancer diagnosis, particularly for screening and non-acute symptomatic patients. While reductions in overall cancer diagnoses have been reported elsewhere, any differential effects on emergency presentations, which are associated with poorer outcomes, have not been described.

Material And Methods: Cross-sectional descriptive study from 2015 to 2021, based on International Cancer Benchmarking Partnership methods, where emergency route to diagnosis is defined as presenting as an emergency admission in the 30 days prior to cancer incidence date.
