The National Comprehensive Cancer Control Program, a Centers for Disease Control and Prevention funded program, supports cancer coalitions across the United States (US) in efforts to prevent and control cancer including development of comprehensive cancer control (CCC) plans. CCC plans often focus health equity within their priorities, but it is unclear to what extent lesbian, gay, bisexual, transgender, queer/questioning, plus (LGBTQ+) populations are considered in CCC plans. We qualitatively examined to what extent LGBTQ+ populations were referenced in 64 U.

We aimed to identify the self-reported reasons for being uninsured and sociodemographic factors associated with uninsurance among lesbian, gay, or bisexual (LGB) adults before and after the Affordable Care Act (ACA). We analyzed the 2013-2018 National Health Interview Survey data using multivariable logistic regression models to estimate the odds of being uninsured and the prevalence of self-reported reasons for not having insurance among LGB adults aged 18-64 years. The study included 2124 LGB adults.

Introduction: We evaluated whether Medicaid expansion (ME) was associated with improved 2-year survival and time to treatment initiation (TTI) among patients with gastrointestinal (GI) cancer.

Methods: GI cancer patients diagnosed 40-64 years were queried from the National Cancer Database. Those diagnosed from 2010 to 2012 were considered pre-expansion; those diagnosed from 2014 to 2016 were considered post-expansion.

Objectives: Palliative care can improve the quality of life of adolescents and young adults (AYA) with cancer. However, little is known about the utilization of palliative care among AYA cancer patients. Identifying factors associated with the utilization of palliative care could inform efforts to improve palliative care access among AYA patients living with cancer.

Purpose Of Review: Substance use is a major public health problem in adolescents and young adults (AYA) and is particularly dangerous for AYA with type 1 diabetes (T1D) due to additional health consequences related to T1D. Rates of substance use among AYA with T1D are difficult to ascertain. Currently, we aim to provide a summary of published rates of substance use, over the last 10 years, among AYA with T1D in the USA.

Article Synopsis
  • The ACIP recommended shared decision-making for HPV vaccination in adults 27-45 in 2019, prompting a study on vaccination trends before and after this update.
  • Researchers analyzed claims data from over 22 million adults to measure changes in HPV vaccine administration rates following this recommendation, focusing on various subgroups.
  • Results showed that the update led to a notable increase in vaccination rates among women, highlighting disparities in vaccination trends among different racial and ethnic groups.

Despite the overall national decline in Kaposi sarcoma (KS) incidence in the United States among persons living with HIV, previous studies suggest there might be specific subgroups of the US population that are associated with higher KS incidence rates than others. Using the 2001-2018 National Program of Cancer Registries and Surveillance, Epidemiology, and End Results Program database, we assessed KS incidence trends among young men aged 20-34 years by race and ethnicity and geographic region. Statistical significance is 2-sided.

Importance: Area-level factors have been identified as important social determinants of health (SDoH) that impact many health-related outcomes. Less is known about how the social vulnerability index (SVI), as a scalable composite score, can multidimensionally explain the population-based cancer screening program uptake at a county level.

Objective: To examine the geographic variation of US Preventive Services Task Force (USPSTF)-recommended breast, cervical, and colorectal cancer screening rates and the association between county-level SVI and the 3 screening rates.

To inform optimal approaches for detecting anal precancers, we performed a systematic review and meta-analysis of the diagnostic accuracy of anal cancer screening tests in different populations with elevated risk for anal cancer. We conducted a literature search of studies evaluating tests for anal precancer and cancer (anal intraepithelial neoplasia grade 2 or worse, AIN2+) published between January 1, 1997 to September 30, 2021 in PubMed and Embase. Titles and abstracts were screened for inclusion and included articles underwent full-text review, data abstraction and quality assessment.

Human papillomavirus (HPV)-associated cancer burden is rising in the United States. Trends in the incidence by county-level income and smoking prevalence remain undescribed. We used the Surveillance, Epidemiology, and End Results 21 database to ascertain HPV-associated cancers during 2000-2018.

Background: Literature shows that limited English proficiency (LEP) influences individual healthcare-seeking behaviors. The Asian population is the fastest-growing racial/ethnic group in the US, and approximately 50% of foreign-born Asians are estimated to live with LEP.

Objective: To examine associations of LEP and patient-provider language concordance (PPLC) with evidence-based cancer screening utilization for cervical, breast, and colorectal cancers among Asian American adults.

Importance: Cervical cancer screening rates are suboptimal in the US. Population-based assessment of reasons for not receiving screening is needed, particularly among women from historically underserved demographic groups.

Objective: To estimate changes in US Preventive Service Task Force guideline-concordant cervical cancer screening over time and assess the reasons women do not receive up-to-date screening by sociodemographic factors.

Background: A discussion about patient's nonmedical needs during treatment is considered a crucial component of high-quality patient-provider communication. We examined whether having a patient-provider discussion about cancer patients' emotional and social needs is associated with their psychological well-being.

Methods: Using the 2016-2017 Medical Expenditure Panel Survey-Experiences with Cancer Survivorship Supplement (MEPS-ECSS) data, we identified the cancer survivors in the United States (US) who reported having a detailed discussion about emotional and social needs during cancer care.

Human papillomavirus (HPV)-associated anal and oropharyngeal cancer incidence has increased in recent years among US women. However, trends in incidence and burden (annual number of cases) of noncervical HPV-associated cancers relative to cervical cancer remain unclear. Using the 2001-2017 US cancer statistics dataset, we evaluated contemporary incidence trends and burden (annual number of cases) of HPV-associated cancers among women by anatomic site, race or ethnicity, and age.

Background: Squamous cell carcinoma of the anus (SCCA) incidence is rising in the United States. Study of incidence trends by stage at diagnosis, age-specific and birth cohort patterns, and trends in mortality could provide evidence for a true increase and etiological clues for the increase in incidence.

Methods: Using the US Cancer Statistics dataset, we examined trends in SCCA incidence (2001-2015) and mortality (2001-2016) rates.
