Results: covered at least one claim 16% of the 13,039 injuries. Over 90 days, mean...

IntroductionHepatocellular carcinoma disproportionately affects minorities. Southern states have high proportions of black populations and prevalence known risk factors. Further research is needed to understand the role southern geography in hepatocellular disparities. This paper examined racial disparities incidence, demographics, tumor characteristics, receipt treatment, all-cause mortality non-southern cancer registries.MethodsSurveillance Epidemiology End Results data were probed 2015...

Abstract Background and Objectives Given the lack of population‐based data in literature, we sought to (1) identify predictors appendiceal carcinoid tumor nodal metastasis distinguish which patients would most likely benefit from hemicolectomy (2) compare survival after versus appendectomy alone. Methods Using Surveillance Epidemiology End Results Database (1988–2005), identified with tumors who underwent resection. We risk factors for using logistic regression models used Kaplan–Meier...

Hip fracture is associated with high morbidity and mortality. Pelvic external beam radiotherapy (EBRT) known to increase the risk of hip fractures in women, but effect men unknown.From Surveillance, Epidemiology, End Results (SEER)-Medicare database, 45,662 who were aged ≥66 years diagnosed prostate cancer 1992-2004 identified. By using Kaplan-Meier methods Cox proportional hazards models, primary outcome was compared among received radical prostatectomy (RP), EBRT, EBRT plus androgen...

Abstract BACKGROUND: Radiation therapy (RT) after breast‐conserving surgery (BCS) is associated with a significant reduction in ipsilateral breast tumor recurrence and cancer mortality rates patients early stage cancer. The authors of this report sought to determine which do not receive RT BCS the United States. METHODS: Surveillance, Epidemiology, End Results registry was used for women I through III States from 1992 2007. A multivariate analysis performed identify independent predictors...

Active surveillance protocols track low risk prostate cancer progression over time. However, given the lack of uniform criteria for managing cancer, men who qualify active might have less intensive and, thus, experience poorer outcomes. In this study we examined racial disparities in frequency and intensity between African-American Caucasian men.Using linked SEER-Medicare data set identified 13,374 with (defined by D'Amico criteria) diagnosed from 2004 to 2009 then followed through 2011. A...

BackgroundUse of androgen suppression therapy (AST) in prostate cancer increased more than threefold from 1991 to 1999. The 2003 Medicare Modernization Act reduced reimbursements for AST by 64% between 2004 and 2005, but the effect this large reduction on use is unknown.

To illustrate the 10-year risks of urinary adverse events (UAEs) among men diagnosed with prostate cancer and treated different types therapy, accounting for competing risk death. Prostate is second most common malignancy adult males in United States. Few studies have reported long-term post-treatment UAEs those that have, not appropriately accounted deaths. This paper conducts an inverse probability treatment (IPT) weighted analysis to estimate effects treatments on UAE, using a...

Disparities in healthcare outcomes between races have been extensively described; however, studies fail to characterize the contribution of differences distribution covariates groups and impact discrimination. This study aims degree which clinicodemographic factors unmeasured confounders are contributing any observed disparities non-Hispanic white black males on surgical after major urologic cancer surgery.Non-Hispanic undergoing radical cystectomy, nephrectomy, or prostatectomy for American...

To use place-of-service (POS) codes in the Medicare hospice claims files to document where elderly users with cancer die.Retrospective cohort study.Surveillance, Epidemiology, and End Results (SEER) registry areas.Elderly beneficiaries who died of lung, breast, colorectal, or pancreatic 2007 2008 (N = 46,037).Use hospice, place service at death (home, nursing home, hospital, inpatient other), length stay hospice.Two-thirds used hospice. Younger, male, black, Asian, unmarried those enrolled...

Abstract Background Medicare Advantage (MA) plans may offer more benefits and lower costs relative to Traditional (TM), but also provide narrower provider networks pre-authorization requirements. We explore the impact of a cancer diagnosis on switching between MA TM after diagnosis. Methods used 2015-2019 Surveillance, Epidemiology End Results-Medicare data examine patterns those without cancer. binomial generalized estimating equations evaluate sociodemographic characteristics with higher...

Prostate cancer treatments can cause long-term urinary adverse events (UAEs), but time-varying risks across remain understudied. Using Surveillance, Epidemiology and End Results-Medicare data, we evaluated men aged ≥66 yr with localized prostate treated radical prostatectomy (RP), external beam radiotherapy (EBRT), brachytherapy (BT), EBRT + BT, RP EBRT, or ablation between 2000 2017. The primary outcome was any UAE requiring a procedure, follow-up from treatment initiation censoring at...

Long-term urinary adverse events (UAEs) following prostate cancer treatment significantly impact survivor quality of life. Previous research suggests disparities in outcomes across geographic and sociodemographic lines, but a comprehensive analysis treatment-related UAEs is lacking. Using SEER-Medicare data (1999-2019), we conducted retrospective cohort study men aged ≥66 with non-metastatic treated within 12 months diagnosis. Rural versus urban residence was determined using Rural-Urban...

Ureteral obstruction in cervical cancer occurs up to 11% of patients, many whom undergo ureteral stenting. Our aim was describe the patient burden chronic stenting a population-based cohort by detailing two objectives: (1) frequency repeat procedures for obstruction; and, (2) urinary adverse effects (UAEs) (e.g., lower tract symptoms, flank pain).From SEER-Medicare, we identified 202 women who underwent stent placement prior or following treatment. The and rate ratios were compared between...

Not only is smoking a risk factor for the development of bladder cancer, it has also been implicated in increasing surgical morbidity and mortality. In general, demographic clinical characteristics smokers are different to non-smokers which can bias results impact smoking.To evaluate on radical cystectomy outcomes.Radical cases were identified National Surgical Quality Improvement Program database from 2007-2015. Smokers matched with using propensity scores 1:1 ratio. Multivariate logistic...

We examined the degree of exclusion bias that may occur due to missing data when grouping prostate cancer cases from SEER (Surveillance, Epidemiology and End Results) database into D'Amico clinical risk groups.
