INTRODUCTION Emerging evidence suggest that microRNAs could serve as non-invasive biomarker for cancer patients. Our study was designed to analyze circulating serum microRNAs in patients with renal cell carcinoma (RCC). MATERIALS AND METHODS Serum RNA was isolated from patients with clear cell RCC (ccRCC) and non-malignant disease; an artificial microRNA(More)
BACKGROUND MicroRNA expression is altered in cancer cells, and microRNAs could serve as diagnostic/prognostic biomarker for cancer patients. Our study was designed to analyze circulating serum microRNAs in patients with renal cell carcinoma (RCC). METHODOLOGY/PRINCIPAL FINDINGS We first explored microrna expression profiles in tissue and serum using(More)
BACKGROUND DNA CpG island hypermethylation causes gene silencing and is a common event in prostate carcinogenesis and progression. We investigated its role as a possible prognostic marker in patients with PCA Gleason score ≤7. PATIENTS AND METHODS We used a quantitative, methylation-specific PCR to analyze methylation patterns at five gene loci (APC,(More)
BACKGROUND/AIM Increased levels of microRNAs in serum/plasma have been identified in various malignancies. We aimed to investigate serum levels of miR-26a-1 and miR-141 in patients undergoing prostate biopsy clinical suspicious for prostate cancer (PCA) in a prospective multi-center study. PATIENTS AND METHODS Pre-biopsy serum samples of 170 patients were(More)
BACKGROUND The Bladder Cancer Research Consortium (BCRC) created nomograms to predict all-cause mortality (ACM), cancer-specific mortality (CSM), and recurrence after radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). OBJECTIVE To perform a formal validation of the BCRC nomograms in a large multi-institutional patient cohort from(More)
AIM The outcome of patients with urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) shows remarkable variability. We evaluated the ability of artificial neural networks (ANN) to perform risk stratification in UCB patients based on common parameters available at the time of RC. METHODS Data from 2111 UCB patients that underwent RC in(More)
BACKGROUND Bladder cancer (UCB) staged pT4a show heterogeneous outcome after radical cystectomy (RC). No risk model has been established to date. Despite gender-specific differences, no comparative studies exist for this tumor stage. MATERIALS AND METHODS Cancer-specific survival (CSS) of 245 UCB patients without neoadjuvant chemotherapy staged pT4a,(More)
INTRODUCTION MicroRNAs play an important role in many human malignancies; so far, their expression remains to be studied in upper urinary tract urothelial cancer (UUTUC). MATERIALS AND METHODS The expression of eleven microRNAs (miR-10a, miR-21, miR-96, miR-135, miR-141, miR-182, miR-200b, miR-205, miR-429, miR-520b, miR-1244) formerly shown to be(More)
Radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) is associated with heterogeneous functional and oncological outcomes. The aim of this study was to generate trifecta and pentafecta criteria to optimize outcome reporting after RC. We interviewed 50 experts to consider a virtual group of patients (age ≤ 75 years, ASA score ≤ 3) undergoing(More)
PURPOSE To perform the first external validation of a recently identified association between disease-free survival at two years (DFS2) or three years (DFS3) and overall survival at five years (OS5) in patients after radical cystectomy (RC) for muscle-invasive urothelial carcinoma of the bladder (UCB). METHODS AND METHODS Records of 2483 patients who(More)
