Human Papillomavirus Vaccination and Human Papillomavirus-Related Cancer Rates.

Importance: To inform the design and implementation of targeted interventions to reduce the future burden of human papillomavirus (HPV)-related cancers in Texas, it is necessary to examine the county and health service region (HSR) levels of (1) the proportion of children and teenagers aged 9 to 17 years who initiated and were up to date for HPV vaccination series and (2) HPV-related cancer incidence rates (IRs).

Objective: To evaluate temporal trends and geospatial patterns of HPV vaccination initiation and up-to-date status as well as HPV-related cancer rates at county and HSR levels in Texas.

Design, Setting, And Participants: This population-based cross-sectional study used data from the Texas Immunization Registry, the National Cancer Institute's Surveillance, Epidemiology, and End Results Program database, and Texas Department of State Health Services annual population counts from 2006 to 2022.

Cervical Cancer Screening Utilization among Kidney Transplant Recipients, 2001 to 2018.

Background: Kidney transplant recipients (KTR) have elevated risks of cervical precancers and cancers and guidelines recommend more frequent cervical cancer screening exams. However, little is known about current trends in cervical cancer screening in this unique population. We described patterns in the uptake of cervical cancer screening exams among female KTRs and identified factors associated with screening utilization.

Temporal Trends in Treatment and Outcomes of Endometrial Carcinoma in the United States, 2005-2020.

Endometrial cancer has continued to see a rising incidence in the US over the years. The main aim of this study was to assess current trends in patients' characteristics and outcomes of treatment for endometrial carcinoma over 16 years. A dataset from the National Cancer Database (NCDB) for patients diagnosed with endometrial carcinoma from 2005 to 2020 was used in this retrospective, case series study.

Cost-Effectiveness of Population-Based Multigene Testing for Breast and Ovarian Cancer Prevention.

Importance: The current method of BRCA testing for breast and ovarian cancer prevention, which is based on family history, often fails to identify many carriers of pathogenic variants. Population-based genetic testing offers a transformative approach in cancer prevention by allowing for proactive identification of any high-risk individuals and enabling early interventions.

Objective: To assess the lifetime incremental effectiveness, costs, and cost-effectiveness of population-based multigene testing vs family history-based testing.

One dose versus two doses of COVID-19 vaccine for the prevention of breakthrough infections among people previously infected with SARS-Cov-2.

Studies have suggested the effectiveness of COVID-19 vaccines in preventing SARS-CoV-2 reinfection among those previously infected. However, it is not yet clear if one dose of the vaccine is enough to prevent breakthrough infections compared to two doses. Using data from Optum deidentified COVID-19 Electronic Health Record (EHR) data set, we assessed breakthrough infection risks in individuals previously infected, comparing those with one vaccine dose to those with two doses.

Hepatocellular Carcinoma Surveillance among Individuals with Cirrhosis: Trends by Payer, Etiology, and Calendar Year, from a Statewide, Multi-Payer Dataset, 2010-2018.

Background: Hepatocellular carcinoma (HCC) surveillance is underutilized, with <25% of individuals with cirrhosis receiving surveillance exams as recommended. The epidemiology of cirrhosis and HCC in the United States has also shifted in recent years, but little is known about recent trends in surveillance utilization. We characterized patterns of HCC surveillance by payer, cirrhosis etiology, and calendar year in insured individuals with cirrhosis.

Incomplete HPV Vaccination among Individuals Aged 27-45 Years in the United States: A Mixed-Effect Analysis of Individual and Contextual Factors.

In the United States, the human papillomavirus (HPV) vaccine is approved for use in individuals up to age 45. Individuals 15 years and older require three doses of the vaccine to complete the recommended dosing series. Incomplete HPV vaccination rates (i.

Incidence of human papillomavirus-related cancers among males and females aged 15-34 years in the United States.

Postmarket surveillance of the incidence of human papillomavirus (HPV)-related cancers is essential to monitor the effectiveness of HPV vaccines. We directly compared HPV-related cancer incidences during the pre- and postvaccine era to assess the effects of HPV vaccination among vaccine-eligible age groups in the United States using data from the US Cancer Statistics database. The 5-year average annual incidence rates for HPV-related cancers decreased in 2015-2019 compared with 2002-2006 among females aged 15-24 years and 25-34 years.

Patterns of first-line targeted therapy utilization and adherence among older adults diagnosed with metastatic renal cell carcinoma.

Background: Despite the rapid approval of targeted therapies for metastatic renal cell carcinoma (mRCC) evidence on real world treatment patterns remains limited. This study evaluated patterns of first-line targeted therapy utilization and adherence in older adults, a population with a high burden of RCC.

Methods: 2093 patients aged ≥66 years with a primary diagnosis of mRCC were identified from United States (US)-based cancer registry and administrative claims data (2007-2015).

Polypharmacy and medication use by cancer history in a nationally representative group of adults in the USA, 2003-2014.

Purpose: This study examines polypharmacy and prescription drug use patterns in cancer survivors, a growing population at risk for cancer sequelae and side effects from treatment, which can arise months or even years following diagnosis. Survivors may experience greater medication burden than the general population, increasing concerns for polypharmacy and subsequent risks of drug interactions and non-adherence.

Methods: Using the National Health and Nutrition Examination Survey (NHANES) data from 2003 to 2014, we examined the association between a cancer history and presence of polypharmacy (5+ medications).

The underreporting of phase III chemo-therapeutic clinical trial data of older patients with cancer: A systematic review.

Purpose: Inspired by the American Society of Clinical Oncology's recommendations to strengthen the evidence base for older adults with cancer, the purpose of this systematic review is to identify the reporting of treatment efficacy and adverse events specific to older adults with cancer in Phase III chemo-therapeutic clinical trials. This review also investigates the frequency with which these data points were reported in the literature to identify gaps in reporting and opportunities to expand the knowledge base on clinical outcomes for older adults with cancer.

Methods: Chemo-therapeutic clinical trial data published from July 1, 2016 to June 30, 2017 was reviewed.

Association between Concomitant Use of Hydrochlorothiazide and Adverse Chemotherapy-Related Events among Older Women with Breast Cancer Treated with Cyclophosphamide.

Background: The pharmacy reference database, Micromedex, lists concomitant hydrochlorothiazide and cyclophosphamide use as a potential, major drug-drug interaction (DDI), although only one small, single-center study supports this claim. Our objective was to estimate associations between this potential DDI and two adverse chemotherapy-related events, neutropenia-related hospitalizations and treatment regimen discontinuation, among a cohort of women with breast cancer initiating adjuvant chemotherapy containing cyclophosphamide.

Methods: Using linked Surveillance, Epidemiology, and End Results Program (SEER)-Medicare data, we included women 66 years and older with breast cancer diagnosis between 2007 and 2011, who initiated a regimen containing cyclophosphamide.

Polypharmacy and Incident Frailty in a Longitudinal Community-Based Cohort Study.

Objectives: Polypharmacy may affect frailty, a common and costly condition among older adults. Frailty prevalence is elevated among racial/ethnic minorities and persons living in the US South, and research is needed to inform future pharmacologic interventions in these populations. Our aim was to quantify the prevalence of frailty and polypharmacy, and to estimate the association between polypharmacy and incident frailty.

Trends in Cigarette Smoking Prevalence Among Refinery and Petrochemical Plant Workers, 1950 to 1999.

Objective: Smoking is a potential confounder in studies of workplace exposures and smoking-related disease, but little data exist to quantitatively adjust for smoking in statistical models.

Methods: We estimated smoking prevalence trends between 1950 and 1999 for 12,299 female and 43,307 male hourly and salaried petrochemical workers using company physical examination data.

Results: Nearly half of hourly male and female employees smoked during the study period, compared with 38% of salaried males and 29% of females.

Breast cancer stage variation and survival in association with insurance status and sociodemographic factors in US women 18 to 64 years old.

Background: Few population-based studies have examined the association between health insurance status and breast cancer stage at diagnosis and survival. The degree to which sociodemographic characteristics explain this association is also unclear. This study examined associations between insurance status and sociodemographic characteristics and stage at diagnosis and survival.
