To investigate the characteristics and outcomes of late recurrence (LR) in patients with bladder cancer (BCa) treated with radical cystectomy (RC) and to identify clinicopathologic predictors of LR and postrecurrence survival.This multicenter study included 1652 BCa patients. LR was defined as occurring more than 5 years after RC. Differences in postrecurrence overall survival according to the timing...
To evaluate potential differences in local tumor ablation (LTA) perioperative outcomes between the percutaneous LTA (pLTA) and the laparoscopic LTA (lapLTA) approaches.Using the Surveillance, Epidemiology, and End Results-Medicare, we identified all patients diagnosed with T1a renal cell carcinoma (RCC) who underwent either pLTA or lapLTA between 2000 and 2009. Overall complications at 30 days and...
To assess postoperative complication profiles and 30-day mortality (30 dM) in older patients undergoing either laparoscopic radical nephrectomy (LRN) compared with open partial nephrectomy (OPN) or laparoscopic partial nephrectomy (LPN) for early stage renal cell carcinoma.Using the Surveillance, Epidemiology, and End Results-Medicare linked database, 2277 patients aged >65 years with T1 renal...
To determine the association of gender with outcome after radical cystectomy for patients with bladder cancer.An observational cohort study was conducted using retrospectively collected data from 11 centers on patients with advanced bladder cancer treated with radical cystectomy. The association of gender with disease recurrence and cancer-specific mortality was examined using a competing risk analysis...
To test whether cancer control outcomes justify the consideration of partial nephrectomy in patients with large tumors (Stage pT2 or greater) or high-grade tumors (Fuhrman grade III-IV) or lesions extending beyond the kidney (Stage pT3a). We abstracted the data for 8847, 11 547, and 5232 patients with tumors >7 cm, Fuhrman grade III-IV, and Stage T3a from the Surveillance, Epidemiology, and...
To examine the effect of annual prostatectomy volume (APV) on contemporary intraoperative rectal laceration (RL) rates after radical prostatectomy. From 1999 to 2008, 36 699 radical prostatectomy procedures were performed in Florida. First, logistic regression models predicting the RL rate were fitted. Second, other logistic regression models were used to examine the association between RL and...
To validate the Briganti nomogram and compare it with 2 current lymph node invasion (LNI) nomograms (the Cagiannos nomogram and the updated 2007 Partin tables). The Briganti nomogram predicts the probability of LNI in patients undergoing extended pelvic lymph node dissection (EPLND) during radical prostatectomy for prostate cancer. Irrespective of the risk of LNI, 173 consecutive patients were...
To examine the homologous blood transfusion (HBT), autologous blood transfusion (ABT) and intraoperative blood conservation technique (IOBCT) rates and trends at open (ORP) and minimally invasive radical prostatectomy (MIRP). The Nationwide Inpatient Sample was queried. Multivariable logistic regression models focused on all three transfusion types. Covariables consisted of procedure specific annual...
A formal validation and head-to-head comparison of the National Comprehensive Cancer Network (NCCN) practice guideline lymph node invasion (LNI) nomogram, Partin tables, and D'Amico risk-classification was conducted for prediction of LNI at radical prostatectomy (RP). We focused on 20,877 patients treated with RP and pelvic lymph node dissection (PLND) between 2004 and 2006 within the Surveillance,...
To revisit whether the perioperative mortality differs between septuagenarian and octogenarian patients and younger patients in a large contemporary population-based cohort. The data from tertiary care centers have suggested that perioperative mortality after radical cystectomy is not considerably different in septuagenarian or octogenarian patients compared with younger patients. However, population-based...
To complement existing data with population-based cancer control outcomes that account for the effect of other-cause mortality (OCM). Cancer control rates are virtually equivalent between partial (PN) and radical nephrectomy (RN) for patients with T1aN0M0 renal cell carcinoma (RCC). To date, only 6 studies from centers of excellence examined cancer control rates after PN vs RN for T1aN0M0 RCC. OCM...
To test whether tumor necrosis (TN) could improve the prognostic ability of the predictors of 2 established prognostic renal cell carcinoma (RCC) models. Presence of TN within the nephrectomy specimen is considered an important prognostic marker in patients with RCC. However, its added prognostic value along with established cancer-specific mortality (CSM) predictors has never been formally tested...
