Updated nomogram predicting lymph node invasion in patients with prostate cancer undergoing extended pelvic lymph node dissection: the essential importance of percentage of positive cores.
BACKGROUND Few predictive models aimed at predicting the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa) treated with extended pelvic lymph node dissection (ePLND) are… Expand

Positive surgical margin appears to have negligible impact on survival of renal cell carcinomas treated by nephron-sparing surgery.
BACKGROUND The occurrence of positive surgical margins (PSMs) after partial nephrectomy (PN) is rare, and little is known about their natural history. OBJECTIVE To identify predictive factors of… Expand

Prognostic factors and predictive models in renal cell carcinoma: a contemporary review.
CONTEXT The natural history of renal cell carcinoma (RCC) is highly unpredictable. Small renal masses may be accompanied by metastatic disease. Conversely, patients with locally advanced disease may… Expand

A preoperative nomogram identifying decreased risk of positive pelvic lymph nodes in patients with prostate cancer.
PURPOSE We developed a preoperative nomogram for prediction of lymph node metastases in patients with clinically localized prostate cancer. MATERIALS AND METHODS The study was a retrospective,… Expand

Complications and other surgical outcomes associated with extended pelvic lymphadenectomy in men with localized prostate cancer.
OBJECTIVES More-extensive pelvic lymph node dissection (PLND) may be associated with a higher rate of complications and a longer hospital stay than more limited PLND. METHODS Before radical… Expand

Positive surgical margins in radical prostatectomy: outlining the problem and its long-term consequences.
CONTEXT This review focuses on positive surgical margins (PSM) in radical prostatectomy (RP). OBJECTIVE To address the etiology, incidence, and oncologic impact of PSM and discuss technical points… Expand

Multi-institutional validation of a new renal cancer-specific survival nomogram.
PURPOSE We tested the hypothesis that the prediction of renal cancer-specific survival can be improved if traditional predictor variables are used within a prognostic nomogram. PATIENTS AND METHODS… Expand

Perioperative outcomes of robot-assisted radical prostatectomy compared with open radical prostatectomy: results from the nationwide inpatient sample.
BACKGROUND Prior to the introduction and dissemination of robot-assisted radical prostatectomy (RARP), population-based studies comparing open radical prostatectomy (ORP) and minimally invasive… Expand

Validation of a nomogram predicting the probability of lymph node invasion among patients undergoing radical prostatectomy and an extended pelvic lymphadenectomy.
INTRODUCTION Our goal was to develop and internally validate a nomogram for prediction of lymph node invasion (LNI) in patients with clinically localized prostate cancer undergoing extended pelvic… Expand
