To assess national utilization patterns for cystectomy and nonsurgical treatments for elderly patients with muscle-invasive bladder cancer.From the National Cancer Database, we identified patients ≥75 years old with T2-T4, non-metastatic urothelial carcinoma between 2003 and 2012. Patients were grouped by treatment: cystectomy, chemoradiation, or nonstandard treatment. Cochran-Armitage trend test...
To evaluate racial disparities in the diagnosis and treatment of penile cancer among a contemporary series of men from a large diverse national data base.Using the 1998-2012 National Cancer Data Base, all men with squamous cell carcinoma (SCC) were stratified by race and ethnicity. Demographic and disease characteristics were compared between groups. Likelihood of undergoing surgery and type of surgery...
To assess the variation in primary treatment of high-risk prostate cancer (PCa) by different hospital characteristics in the United States.We used the National Cancer Data Base to identify patients diagnosed with pretreatment high-risk PCa from 2004 to 2011. The primary outcomes were different forms of primary therapy or watchful waiting (WW) across different types of hospitals (community, comprehensive...
To assess the national utilization of partial nephrectomy (PN) for T1a renal masses across different racial groups by hospital type. Although clinical guidelines recommend PN for small renal masses (SRMs), racial disparities persist in the use of PN. High-volume and academic hospitals have been associated with greater use of PN for SRMs. However, it is unknown whether racial disparities persist in...
To describe recent temporal trends in biopsy use for renal cell carcinoma and to identify factors associated with biopsy.Renal cell carcinoma diagnoses from 2003 to 2011 were identified using the National Cancer Data Base. Cases were classified by traditional (clinical stage T4, N1, or M1, or history of other malignancies) or expanded biopsy indications. Time trends were plotted, and multivariate...
To assess national trends in the usage of local ablative therapy for small renal masses (SRMs) in a cohort of young patients. Ablation of SRMs has been shown to offer cancer control with limited follow-up. Although ablation is considered effective for patients with limited life expectancy, its use among younger patients may be considered controversial.We used the National Cancer Data Base to identify...
To determine the rate of observation utilization over time and to identify factors influencing its use.Using the National Cancer Data Base, we studied observation utilization in patients diagnosed with localized renal cell carcinoma from 2003 to 2010. Relationships between temporal, demographic, provider, and clinical factors and the likelihood of observation were evaluated using multivariate logistic...
To assess the utilization of immunotherapy after the advent of tyrosine-kinase inhibitors and mammalian target of rapamycin inhibitors for metastatic renal cell carcinoma (RCC) in the United States, as well as to better understand the variables associated with the implementation of these systemic therapies.The National Cancer Data Base Participant User File for Renal Cancer was queried. Patients diagnosed...
To determine if utilization of surveillance or adjuvant chemotherapy has increased compared with that of adjuvant radiotherapy (ART) in clinical stage I seminoma (CSIS) and to estimate the impact of this utilization trend on secondary malignancies.The National Cancer Data Base, a web-based data analysis tool was examined for first-course adjuvant therapy management in CSIS from 2000 to 2008. We assessed...
Up to 10% of patients who have undergone the Bricker ileal conduit urinary diversion may develop ureteroileal anastomotic complications that are more frequently associated with the left side ureter. We have therefore modified the standard Bricker ileal conduit technique to minimize the anastomotic complications associated with the left side ureter.In our modification, the proximate end of the ileal...
To verify the ability to identify the layered structures of the ureteral wall and to image a segment of the ureter in 3 dimensions with high-speed, endoscopic optical coherence tomography (EOCT).We imaged a porcine ureter ex vivo using a spectral-domain EOCT with a specially designed circumferential scanning fiber catheter. The images were correlated with the histologic findings to identify the corresponding...
To compare the pathologic outcomes and prostate-specific antigen (PSA) progression rates of patients who underwent radical prostatectomy because of prostate cancers and whose cancer was detected at a PSA level of 2.6 to 4.0 ng/mL versus those with cancer detected after the PSA level rose to greater than 4.0 ng/mL. Some studies have suggested that clinically significant prostate cancer is detected...
