Objective Relative to urban populations, rural patients may have more limited access to care, which may undermine timely bladder cancer (BCa) diagnosis and even survival. Methods We tested the effect of residency status (rural areas [RA Results Of 222,330 patients, 3496 (1.6%) resided in RA, 25,462 (11.5%) in UC and 193,372 (87%) in UA. Age, tumor stage, radical cystectomy rates or chemotherapy use were comparable between RA, UC and UA (all p > 0.05). At 10 years, RA was associated with highest OCM followed by UC and UA (30.9% vs. 27.7% vs. 25.6%, p Conclusion We did not observe meaningful differences in access to treatment or stage distribution, according to residency status. However, RA and to a lesser extent UC residency status, were associated with higher OCM and marginally higher CSM in T1N0M0 patients. This observation should be further validated or refuted in additional epidemiological investigations.

ABSTRACT OBJECTIVE To identify factors associated with nonmuscle invasive bladder cancer (NMIBC) American Urological Association (AUA) guideline compliance in a rural state, to evaluate compliance rates over time, and to assess the impact of patient and provider rurality on delivery of NMIBC care. METHODS We identified 847 Iowans in Surveillance, Epidemiology, and End Results-Medicare from 1992 to 2009 with high-grade NMIBC who survived 2 years and were not treated with cystectomy or radiation d...

: Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated. The aims of this study were to investigate whether there are differences in the cancer incidence and 5-year survival rates in Utah by metropolitan/rural residence and to investigate disparities in distributions of cancer risk factors. We used cancer registry records to identify patients diagnosed with a first primary cancer in Utah between 2004 and 2008. We estimated ...

Abstract Objective To evaluate rural/urban disparities in 30-day all-cause hospital admission after cystectomy. Materials and methods We used the SEER-Medicare database to identify all Medicare beneficiaries who underwent radical cystectomy (ICD-9 codes 57.7, 57.71, 57.79, and 68.8) between the years 1991 and 2009, yielding a total sample size of 15,572. Our primary outcome was 30-day hospital readmission rate. Rural Urban Continuum Codes were used to designate county-level rural status based on...

Abstract Context Tumour grade is an important prognostic indicator in non–muscle-invasive bladder cancer (NMIBC). Histopathological classifications are limited by interobserver variability (reproducibility), which may have prognostic implications. European Association of Urology NMIBC guidelines suggest concurrent use of both 1973 and 2004/2016 World Health Organization (WHO) classifications. Objective To compare the prognostic performance and reproducibility of the 1973 and 2004/2016 WHO gradin...

This study examined disparities in lung cancer mortality rates among US men and women in metropolitan and non-metropolitan areas from 1950 through 2007. Annual age-adjusted mortality rates were calculated for men and women in metropolitan and non-metropolitan areas, and differences in mortality rates were tested for statistical significance. Log-linear regression was used to model annual rates of change in mortality over time, while Poisson regression was used to estimate relative risk after adj...

Abstract Background Management of T1 bladder cancer (BCa) is controversial. Objective Evaluate the impact of substage on the clinical outcome of T1 BCa. Design, setting, and participants The T1 diagnosis of 134 first-diagnosis BCa patients from two university hospitals was confirmed. For the T1 substage, we used a new system that discerns T1-microinvasive (T1m) and T1-extensive-invasive (T1e) tumors. We then determined the invasion of the muscularis mucosae–vascular plexus (MM-VP): T1a (invasion...

Introduction: Most previous studies have investigated either socioeconomic deprivation or urbanization in relationship to lung cancer incidence or survival. We investigated the association between socioeconomic deprivation, urbanization, and lung cancer incidence and survival in England. Methods: We extracted data on patients diagnosed with lung cancer (ICD-10 C33-C34) between 2003 and 2007 and who were resident in England. We assigned each patient to an urbanization score and to a socioeconomic...

The clinical importance of human epidermal growth factor receptor-2 (HER2) in breast cancer is now clearly established, given that expression of this tumor marker is used to guide therapy and as a prognostic indicator. Despite its now routine evaluation in breast cancer patients, population-based data are lacking because information on HER2 status is not routinely collected in the majority of population-based cancer registries. We assessed the feasibility of collecting HER2 data and its complete...

Competing events can preclude the event of interest from occurring in epidemiologic data and can be analyzed by using extensions of survival analysis methods. In this paper, the authors outline 3 regression approaches for estimating 2 key quantities in competing risks analysis: the cause-specific relative hazard (csRH) and the subdistribution relative hazard (sdRH). They compare and contrast the structure of the risk sets and the interpretation of parameters obtained with these methods. They als...

Objective: To determine the extent of evidence for a rural–urban health differential in cancer and cancer risk in South Australia Design: Secondary analysis and synthesis of data available between 1977 and 2000 from the publications of the South Australian Cancer Registry and reports of population health surveys carried out by the South Australian Department of Human Services. Results: The mean annual age-standardised incidence of all forms of cancer combined was about 4% lower for rural residen...

Abstract Objective To test for baseline prostate cancer characteristics and survival differences after salvage radical prostatectomy (SRP) across 18 Surveillance, Epidemiology and End Results (SEER) registries from 2004 and 2016. Material and Methods We tabulated PSA, cT-stage, age and SRP rates across individual SEER registries. Kaplan-Meier and competing risks regression methodologies depicted cancer-specific mortality (CSM) and other cause mortality (OCM). Finally, overall mortality (OM) was ...
