Introduction: In clear cell renal cell carcinoma (ccRCC), intravascular extension often results in neoplastic thrombus formation, impacting patient outcomes.
Material And Methods: We assessed P-selectin glycoprotein ligand-1 (PSGL-1) expression in the primary tumours and thrombi of 82 ccRCC patients.
Results: Notably, PSGL-1 expression varied between tumour compartments, with higher prevalence in thrombus tumour cells (TC) and primary tumour-associated immune cells (TAIC).
Radical cystectomy (RC) remains a mainstay surgical treatment for non-metastatic muscle-invasive and BCG-unresponsive bladder cancer. Various perioperative scoring tools assess comorbidity burden, complication risks, and cancer-specific mortality (CSM) risk. We investigated the prognostic value of these scores in patients who underwent RC between 2015 and 2021.

Methods: Data from 229 men with LUTS, diagnosed with DU or BOO on a pressure-flow study (PFS), were retrospectively analyzed, including medical history, Core Lower Urinary Tract Symptoms score (CLSS) questionnaire, UFL and PFS. Uni- and multivariate logistic regression were utilized for the prediction analyses.
The currently available EORTC, CUETO and EAU2021 risk stratifications were originally developed to predict recurrence and progression in non-muscle-invasive bladder cancer (NMIBC). However, they have not been validated to differentiate between high-grade (HG) and low-grade (LG) recurrence-free survival (RFS), which are distinct events with specific implications. We aimed to evaluate the accuracy of available risk models and identify additional risk factors for HG RFS and PFS among NMIBC patients treated with Bacillus Calmette-Guérin (BCG).

Introduction: This study aimed to evaluate cancer-specific (CSM) and other-cause mortality (OCM) in elderly patients with prostate cancer treated with radical prostatectomy (RP) and postoperative radiotherapy (RT).
Material And Methods: The Surveillance, Epidemiology, and End Results (SEER) database was searched for clinically non-metastatic prostate cancer (PCa) treated with RT after RP between 2010 and 2015. Patients were stratified according to age groups and underwent propensity score (PS) matching.
Background: Systemic and local recurrences of urothelial bladder cancer (UBC) significantly impair survival after radical cystectomy (RC), but little is known about the impact of the recurrence of urothelial cancer in the upper urinary tract (UTUC). This report describes survival outcomes and their predictors for patients who underwent RC followed by radical nephroureterectomy (RNU) for UTUC.
Methods: The Surveillance, Epidemiology, and End Results database was queried to identify patients who underwent RC for UBC and subsequent RNU for UTUC.
Prostate cancer (PCa) is a low tumor mutational burden (TMB) cancer with a poor response to immunotherapy. Nonetheless, immunotherapy can be useful, especially in metastatic castration-resistant PCa (mCRPC). Increased cytotoxic T lymphocytes (CTLs) density is correlated with a shorter overall survival (OS), an early biochemical relapse, and a generally poor PCa prognosis.

This study aimed to compare the oncological outcomes of RNU and KSS in patients with UTUC.
Methods: We searched the SEER database for patients treated for primary non-metastatic UTUC with either RNU or a kidney-sparing approach (segmental ureterectomy (SU) or local tumor excision (LTE)) between 2004 and 2018.
The benefit of lymph node dissection (LND) during radical nephroureterectomy (RNU) in lymph node (LN)-negative (cN0/pN0) UTUC remains controversial. We aimed to assess the association between LND and its extent and survival in LN-negative UTUC. The Surveillance, Epidemiology, and End Results database was searched to identify patients with non-metastatic chemotherapy-naïve cN0/pNx or pN0 UTUC who underwent RNU +/- LND between 2004 and 2019.
View Article and Find Full Text PDFBackground And Purpose: Non-muscle-invasive bladder cancer (NMIBC) constitutes a heterogeneous group of tumors with different prognoses. This population-based study aimed to report real-world cancer-specific survival (CSS) of NMIBC and create a prognostic nomogram based on the identified risk factors.
Methods: The Surveillance, Epidemiology, and End Results database was searched for patients diagnosed with NMIBC from 2004 to 2015, who underwent transurethral resection of the bladder tumor.
Background: Patients with nonmetastatic prostate cancer (nmPCa) and high prostate-specific antigen (PSA) levels due to the high likelihood of metastasis pose a clinical dilemma regarding their optimal treatment and long-term outcomes after initial local therapy. We aimed to evaluate the oncologic outcomes of patients treated with radical prostatectomy (RP) or radiotherapy (RT) for nmPCa with high PSA levels.
Methods: We queried the Surveillance, Epidemiology, and End Results (SEER) database to identify patients diagnosed with nmPCa who received RP or RT from 2004 through 2015.
Purpose: To identify the risk factors for 5-year cancer-specific (CSS) and overall survival (OS) and to compare the accuracy of logistic regression (LR) and artificial neural network (ANN) in the prediction of survival outcomes in T1 non-muscle-invasive bladder cancer.
Methods: This is a population-based analysis using the Surveillance, Epidemiology, and End Results database. Patients with T1 bladder cancer (BC) who underwent transurethral resection of the tumour (TURBT) between 2004 and 2015 were included in the analysis.
Purpose: The reliability of magnetic resonance imaging (MRI) as a local and nodal staging tool in radio-recurrent prostate cancer (PCa) is still unclear. The present study aims at evaluating the predictive value of MRI in the detection of extracapsular extension (ECE), seminal vesical invasion (SVI) and nodal involvement (LNI) in patients after primary radio (EBRT) and/or brachytherapy (BT) before salvage radical prostatectomy (SRP).
Methods: This systematic review and meta-analysis were performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.
This paper presents the results of an analysis of the changes in the stiffness of asphalt binders modified with a bio-flux additive and subjected to the processes of foaming and short-term ageing. The purpose of the analyses was to determine changes in the rheological properties of asphalt binder as a result of technological processes characteristic of hot and warm mix asphalt technology. Three asphalt binders with similar penetration but varying degrees of polymer modification were tested: 50/70, 45/80-55 polymer-modified bitumen, and 45/80-80 highly modified bitumen.
