Postoperative nomogram for invasive bladder cancer: does it really work? A multicenter cohort study.

2011

Objectives: Nomograms are statistical models designed to maximize predictive accuracy. We have tested the statistical correlation between the predictions of International Bladder Cancer Nomogram Consortium and the clinical outcomes in a multicenter Italian cohort of patients treated with radical cystectomy (RC) and pelvic lymph-nodes dissection. Methods and materials: Two hundred four patients who underwent RC were selected for multiple variable and then enrolled in the study. Patients were tested by the "online tool" based on the nomogram, then stratified and risk grouped for 5-year predicted disease-free survival (pDFS): low risk (67%-100%), intermediate risk (34%-66%), and high risk grou…

Chromophobe renal cell carcinoma (RCC): oncological outcomes and prognostic factors in a large multicentre series.

2011

Study Type - Outcomes (cohort) Level of Evidence 2b What's known on the subject? and What does the study add? About 80% of RCCs have clear cell histology, and consistent data are available about the clinical and histological characteristics of this histological subtype. Conversely, less attention has been dedicated to the study of non-clear cell renal tumours Specifically, published data show that chromophobe RCC (ChRCC) have often favourable pathological stages and better nuclear grades as well as a lower risk of metastasizing compared with clear cell RCC (ccRCC). Patients with ChRCC were shown to have significantly higher cancer-specific survival (CSS) probabilities compared with ccRCC. H…

Transperitoneal vs retroperitoneal minimally invasive partial nephrectomy: comparison of perioperative outcomes and functional follow-up in a large m…

2020

Abstract Background Aim of this study was to evaluate and compare perioperative outcomes of transperitoneal (TP) and retroperitoneal (TR) approaches in a multi-institutional cohort of minimally invasive partial nephrectomy (MI-PN). Material and methods All consecutive patients undergone MI-PN for clinical T1 renal tumors at 26 Italian centers (RECORd2 project) between 01/2013 and 12/2016 were evaluated, collecting the pre-, intra-, and postoperative data. The patients were then stratified according to the surgical approach, TP or RP. A 1:1 propensity score (PS) matching was performed to obtain homogeneous cohorts, considering the age, gender, baseline eGFR, surgical indication, clinical dia…

How radical prostatectomy procedures have changed over the last 10 years in Italy: a comparative analysis based on more than 1500 patients participat…

2020

Purpose Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. Methods The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). Results The two cohorts did not …

External validation of the preoperative Karakiewicz nomogram in a large multicentre series of patients with renal cell carcinoma

2012

Purpose: To perform a formal external validation of the preoperative Karakiewicz nomogram (KN) for the prediction of cancer-specific survival (CSS) using a large series of surgically treated patients diagnosed with organ-confined or metastatic renal cell carcinoma (RCC). Methods: Patient population originated from a series of retrospectively gathered cases that underwent radical or partial nephrectomy between years 1995 and 2007 for suspicion of kidney cancer. The original Cox coefficients were used to generate the predicted risk of CSS at 1, 2, 5, and 10 years following surgery and compared to the observed risk of CSS in the current population. External validation was quantified using meas…

Early outcomes and complications following cardiac surgery in patients testing positive for coronavirus disease 2019: An international cohort study

2021

The outbreak of severe acute respiratory syndromecoronavirus-2, the cause of coronavirus disease 2019 (COVID-19) in December 2019 represented a global emergency accounting for more than 2.5 million deaths worldwide.1 It has had an unprecedented influence on cardiac surgery internationally, resulting in cautious delivery of surgery and restructuring of services.2 Understanding the influence of COVID-19 on patients after cardiac surgery is based on assumptions from other surgical specialties and single-center studies. The COVIDSurg Collaborative conducted a multicenter cohort study, including 1128 patients, across 235 hospitals, from 24 countries demonstrating perioperative COVID-19 infection…

Elective partial nephrectomy is equivalent to radical nephrectomy in patients with clinical T1 renal cell carcinoma: results of a retrospective, comp…

2012

Study Type - Therapy (cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Few studies supported the expanded indications for nephron-sparing surgery (NSS) in selected patients with 4.1 cm renal tumours in the size range (T1b). However, all these comparative studies included both imperative and elective partial nephrectomy and patient selection for analysis was based on pathological stage (pT1) and not on clinical stage (cT1). Patients with clinically organ-confined RCC (cT1) who are candidates for elective PN have a limited risk of clinical understaging. NSS is not associated with an increased risk of recurrence and cancer-specific mortality both in cT1a a…

Time to recurrence is a significant predictor of cancer-specific survival after recurrence in patients with recurrent renal cell carcinoma - Results …

2013

Objectives To assess the prognostic impact of time to recurrence (TTR) on cancer-specific survival (CSS) after recurrence in patients with renal cell carcinoma (RCC) undergoing radical nephrectomy or nephron-sparing surgery. To analyse differences in clinical and histopathological criteria between patients with early and late recurrence. Patients and Methods Of 13 107 patients with RCC from an international multicentre database, 1712 patients developed recurrence in the follow-up (FU), at a median (interquartile range) of 50.1 (25-106) months. In all, 1402 patients had recurrence at ≤5 years (Group A) and 310 patients beyond this time (Group B). Differences in clinical and histopathological…
