Abstract
BACKGROUND: Although there is level I evidence demonstrating the superiority of intravesical therapy in patients with bladder cancer, surveillance strategies are primarily founded on expert opinion. The authors examined compliance with surveillance and treatment strategies and the pursuant impact on survival in patients with high-grade disease. METHODS: Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data, the authors identified subjects with a diagnosis of high-grade, non–muscle-invasive disease between 1992 and 2002 who survived 2 years and did not undergo definitive treatment during that time. Nonlinear mixed-effects regression analyses was used to examine compliance with surveillance and treatment strategies. After adjusting for confounders using a propensity score-weighted approach, the authors determined whether individual and comprehensive strategies during the initial 2 years after diagnosis were associated with survival after 2 years. RESULTS: Of 4790 subjects, only 1 received all the recommended measures. Although mean utilization for most measures significantly increased after 1997, only compliance with an induction course of bacillus Calmette-Guerin (BCG) increased (13% to 20%; P < .001). On multivariate analysis, compliance with ≥ 4 cystoscopies, ≥ 4 cytologies, and BCG instillation was found to be lower among octogenarians and higher among those with undifferentiated, Tis, and T1 tumors, and among those individuals diagnosed after 1997. Subjects compliant with these measures had a lower hazard of mortality (hazard ratio, 0.41; 95% confidence interval, 0.18-0.93) than those who received < 4 cystoscopies, < 4 cytologies, and no BCG. CONCLUSION: There was a statistically significant survival advantage found among those who received at least half of the recommended care. Improving compliance with these process-of-care measures via systematic quality improvement initiatives serves as the primary target to meliorate bladder cancer care.

Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data regarding cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Incidence and death rates are age-...

BACKGROUND: Given the uncertainty surrounding the optimal management for early stage bladder cancer, physicians vary in how they approach the disease. The authors of this report linked cancer registry data with medical claims to identify the sources of variation and opportunities for improving the value of cancer care. METHODS: By using data from the Surveillance, Epidemiology, and End Results-Medicare database (1992-2005), patients with early stage bladder cancer were abstracted (n = 18,276). T...

BACKGROUND: Early stage bladder cancer is a heterogeneous disease with a variable risk of progression and mortality. Uncertainty surrounding the optimal care for these patients may result in a mismatch between disease risk and treatment intensity. METHODS: Using Surveillance, Epidemiology, End Results-Medicare data, we identified patients diagnosed with early stage bladder cancer (n = 24,980) between 1993 and 2002. We measured patients' treatment intensity by totaling all Medicare payments made ...

Background Phase III clinical trials performed primarily outside the United States (U.S.) demonstrate that intravesical instillation of chemotherapy immediately following transurethral resection of a bladder tumor (TURB) decreases recurrence rates. We sought to determine whether U.S. urologists have adopted this practice, and its potential effect on costs of bladder cancer (BC) care.

Background Bladder cancer is among the most prevalent and expensive to treat cancers in the United States. In the absence of high-level evidence to guide the optimal management of bladder cancer, urologists may vary widely in how aggressively they treat early-stage disease. We examined associations between initial treatment intensity and subsequent outcomes. Methods We used the Surveillance, Epidemiology, and End Results-Medicare database to identify patients who were diagnosed with early-stage ...

Purpose: In response to variations in cancer care organizations have developed clinical guidelines. In the case of nonmuscle invasive bladder cancer, also known as superficial bladder cancer, 2 similar sets of guidelines were released in the late 1990s that provide care recommendations. We examined patterns of intravesical therapy use in nonmuscle invasive bladder cancer in 2003 to determine whether disparities remained in the quality of cancer care.Materials and Methods: Data from the SEER (Sur...

OBJECTIVE Intravesical therapy (IVT), chemo and immunotherapy, has made conservative, bladder-sparing strategies a viable option for managing patients with high grade T1 bladder cancer. However, many of these patients will have recurrence and occasionally progression, questioning delayed intervention. This study examines the patterns of use of IVT in high-grade T1 bladder cancer and the subsequent impact on survival for patients ultimately proceeding to radical cystectomy (RC). PATIENTS AND METH...

Objectives Surveillance of early-stage bladder cancer (cTis-T1) permits bladder preservation with conservative treatments, using cystectomy to salvage patients with refractory disease. Despite close observation, some tumors progress to muscle invasion during this period. Historically, some believed that cystectomy applied in this setting could provide a better outcome in patients with “early” cT2 disease compared with those with de novo cT2 disease. We compared the pathologic and survival outcom...

Background The relationship between guideline adherence for radical cystectomy of non-muscle-invasive bladder cancer and patient prognoses currently remains unclear. We investigated whether guideline adherence at the time of non-muscle-invasive bladder cancer affects the oncological outcomes of bladder cancer patients who underwent radical cystectomy. Methods Among 267 cTa-4N0-2M0 bladder cancer patients, 70 who underwent radical cystectomy under the non-muscle-invasive bladder cancer or muscle-...

Abstract Bladder cancer may present management challenges as it frequently recurs and can progress when not expeditiously diagnosed and carefully monitored following initial therapy for non-invasive disease. Cystoscopy and cytology have long been the primary tools for the urologist treating bladder cancer. However, as a host of potential biomarkers have been developed, new avenues for non-invasive testing have become available in the detection, surveillance, and prognostic setting. Analysis of u...

Background Long non-coding RNAs (lncRNAs) are essential regulators for various human cancers. However, these lncRNAs need to be further classified for cancer. In the present study, we identified novel competing endogenous RNA (ceRNA) network for bladder cancer (BC) and explored the gene functions of the ceRNA regulatory network. Methods Differential gene expression analysis were performed on The Cancer Genome Atlas Urothelial Bladder Carcinoma (TCGA-BLCA) datasets to identify differentially expr...

BACKGROUND Nonmuscle-invasive bladder cancer (NMIBC) has heterogeneous recurrence and progression outcomes. Available risk calculators estimate recurrence and progression but do not predict the recurrence stage or grade, which may influence downstream treatment. The objective of this study was to predict risk-stratified NMIBC recurrence and progression based on recurrence tumor classification and grade. METHODS In total, 2956 patients with NMIBC (

Due to the constant need for improvement in the quality of education, there has been a growing interest in technological tools to support design for teaching and learning in a student-centered way. As a result, the development of these tools has increased. However, it is not clear what shapes teachers' design decisions and how tools can best support their design processes. Also, researches on Virtual Learning Environments (VLEs) have shown that teachers usually do not explore VLEs to their full ...
