Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project)
PURPOSE: to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). 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. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS: Overall, 2076 patients treated wi…
Epidermal Growth Factor Receptor (EGFR) Cell Expression During Adjuvant Treatment After Transurethral Resection for Non-Muscle-Invasive Bladder Cancer: A New Potential Tool to Identify Patients at Higher Risk of Disease Progression
Abstract Background The aim of the study was to investigate the feasibility of Epidermal Growth Factor Receptor (EGFR) measurement in bladder washings of patients affected by non–muscle-invasive bladder cancer (NMIBC) and its prognostic role in identifying risk subgroups and predicting disease recurrence and progression. Patients and Methods Patients with NMIBC treated with transurethral resection of bladder tumor (TURBT) from 2012 to 2015 were enrolled. Samples of bladder washings were collected and stored at −80°C until RNA extraction. The cDNA obtained from RNA was used to perform a gene expression analysis by a real time polymerase chain reaction. Results An adequate cellular pellet was…
