Exploratory Analysis Of The Spatial Distribution Of Adult Glioma Age-Adjusted County Incidence Rates, Nebraska Medicine, 2009-2019, Kendra Ratnapradipa, Amulya Yellala, Nicole Shonka

Journal Articles: Epidemiology

BACKGROUND: Central nervous system (CNS) cancers including gliomas have low incidence but high mortality. The age-adjusted incidence rate for CNS cancers is higher in Nebraska than nationally. This exploratory study was motivated by glioma patient inquiries about possible clustering of cases within the state to see if more in-depth investigation was warranted.

METHODS: Using electronic health records from Nebraska Medicine, we identified Nebraska adult (age ≥19) glioma patients diagnosed between January 1, 2009 and November 1, 2019. Patient residential addresses were geocoded, mapped, and combined with annual US Census data to compute age-adjusted incidence rates (AAIR) at the county level. …

Manuscripts: Epidemiology

Background: The number of cancer survivors continues to increase due to dramatic improvements in cancer treatment, accounting for approximately 5% of the entire population. As cancer survivors continue to live longer, it is important to understand their quality of life (QoL) in order to maximize supportive care efforts.

Objectives: In this study, the quality of life (QoL) among patients with different types of cancer was examined. The objectives were to: 1) compare patient-reported outcome measures of QoL using the Short-Form (SF-36) Health Survey scores among patients of different cancer types and 2) identify demographic, oncologic, and clinical factors that are …

A Cross-Sectional Analysis Of Adverse Childhood Experience Exposure On Cancer Diagnosis Utilizing The 2022 Behavioral Risk Factor Surveillance Survey Data, Emma Zipperer

Capstone Experience

Objective: To determine the association between Adverse Childhood Experiences (ACEs) and cancer diagnosis based on ACE exposure levels.

Methods: We utilized data collected in the 2022 Behavioral Risk Factor Surveillance System (BRFSS) survey. The study population (n=54,148) was restricted to states that reported on the optional model of experiencing ACEs and those who responded about cancer diagnosis. A univariate analysis, bivariate analysis and a multivariate logistic regression were performed. Odds of cancer diagnosis among those with differing ACE exposure levels were calculated.

Results: High ACE exposure had 20% higher odds of cancer diagnosis when compared to low ACE exposure. White, …

Occupational Exposures Associated With Thyroid Cancer In The Thyroid Tumor And Cancer Collaborative Registry In The Integrated Cancer Center Repository For Cancer Research, James Buckley

Capstone Experience

Thyroid cancer is one of the fastest growing cancers in the United States, with the rate of new cases increasing from 5.2 per 100,000 in 1985 to 13.8 per 100,000 in 2019, with a peak of 14.5 per 100,000 in 2015. Increased thyroid cancer incidence is associated with certain occupations, including healthcare and agriculture. Most existing literature on occupational exposures and thyroid cancer evaluate their association in terms of occupation type and thyroid cancer, rather than specific occupational exposures and thyroid cancer. This study sought to utilize the wide range of occupational exposure data in the Integrated Cancer Center Repository …

Trends Of Human Papilloma Virus- Related Cancers And Hpv Vaccination In Nebraska From 2010 To 2018, Christelle Massumbu

Capstone Experience

Background:

Approximately 46,143 human papillomaviruses (HPV) related cancers are diagnosed annually in the United States. Although the HPV vaccine has been available in the United States since 2006, more than half of adolescents have not completed the HPV vaccine series. In Nebraska, the incidence rates of HPV-related cancers have increased from 2006 (5.7%) to 2018 (6.3%). Although cervical cancer has been highly studied, there is limited research and surveillance on head and neck, vaginal, vulvar, anal, and penile cancers in a state such as Nebraska, which experiences limited access to healthcare in its rural areas. Clarity about these aspects could …

One such program, Youth Enjoy Science at the University of Nebraska Medical Center, has employed American Indian/Alaska Native youth in mentored cancer research internships from 2017 to 2022. The primary purpose of this study was to examine mentor and mentee experiences of participation in Youth Enjoy Science research education internships to learn from their stories. We conducted semi-structured interviews with current and former Youth Enjoy Science mentees (n=8) and mentors (n=8). We analyzed and collectively re-storied the …

Burden And Risk Of Non-Aids Defining Cancers In Hiv-Infected Persons Receiving Antiretroviral Therapy, Brittney L. Dickey

Theses & Dissertations

The burden of cancers not previously associated with an HIV infection, called non-AIDS defining cancers (NADCs), have increased in the years since highly active anti-retroviral therapy has been introduced. The studies in this dissertation attempted to quantify this burden via incidence and mortality compared to the general population. Further, an assessment of risk factors and creation of a predictive risk model, a nomogram, were utilized to better understand how factors associated with demographics, lifestyle, and immune response affected risk for an NADC diagnosis once therapy was initiated and HIV better controlled. Standardized incidence and mortality ratios showed that burden of …

Comorbidity Profile Of Head And Neck Cancer Patients With And Without Depression, Michaela Frenzel

Capstone Experience

This population-based retrospective study used SEER-Medicare data from 2002-2010 to assess depression, comorbidity, and substance use in the elderly head and neck cancer population. Out of 3,533 head and neck cancer patients, 10.6% had depression diagnoses two years prior to cancer diagnosis, 8.9% were newly diagnosed with depression within one year after cancer diagnosis, and 44.5% of those with preexisting depression had an additional depression diagnosis within one year following cancer diagnosis. Comorbid conditions (p<0.0001) and substance use (p=0.0017) showed associations with depression prior to cancer diagnosis yet, no significant associations with incidence of depression in this head and neck cancer population. This study affirms the need for continual depression screenings in head and neck cancer patients and suggests the need for increased research into the burden of comorbid conditions and substance use within the head and neck cancer population.

Characterization Of Cancer Incidence In Chronic Kidney Disease Patients: A Single Center Study, 2008 – 2018, Jagadeesh Puvvula

Capstone Experience

Background: Chronic kidney disease (CKD) is an established risk factor for cardiovascular disease, but the significance of lower Glomerular filtration rate on incidence and mortality from cancer is uncertain. There is evidence that cancer risk and cancer mortality may be increased in individuals with End Stage Renal Disease (ESRD) requiring dialysis or after renal transplantation but whether less severe kidney disease is associated with cancer remains poorly understood.

Some studies indicate that these associations do appear to be organ specific. It has been reported that reduced renal function is associated with an increased risk of cancers of the kidney and …

The Survival And Treatment Refusal Of Lung Cancer Patients: Analyses Of National Cancer Registries, Poppy Deviany

Theses & Dissertations

Lung cancer is the second most commonly diagnosed cancer and the leading cause of cancer mortality of both genders in the United States. A recent report suggests that the relative five-year survival rate of lung cancer is only 18%. Studies indicate many factors are associated with the survival of lung cancer patients, including age at diagnosis. It is widely known as a disease of older people, but the literature shows a substantial number of young people have been diagnosed with lung cancer. The literature also indicates that the refusal of recommended treatment contributes to cancer-related death and poorer survival. The …

Matters Of Trust: Examination Of The Patient-Provider Relationship In Cancer Care, Krista A. Brown

Capstone Experience

Background: The intangible concept of trust is critical in the patient-provider relationship. Cancer patients may experience positive and negative impacts of trust in this relationship to a higher degree due to the inherently serious nature of their disease and the level of dependence upon treatment providers.

Objective: The goal of this study was to compare colorectal cancer patients’ levels of trust in their primary care physician and oncologist, along with examining trust differences associated with demographics and other characteristics.

Methods: Colorectal cancer patients (n=158) treated at Nebraska Medicine and consented into the Integrated Cancer Repository for Cancer Research IRB …

Psychological Aspects Of Head And Neck Cancer, Katherine Rieke

Theses & Dissertations

Patients with head and neck cancer may be at increased risk for depression diagnosis when compared to other cancer sites, both before and after their cancer diagnosis. Behavioral risk factors for head and neck cancers, including tobacco and alcohol use, may be indicative of depression before cancer diagnosis. Further, head and neck cancers and their treatments can cause serious morbidity among patients, including physical disfigurement and loss of function. Additionally, these cancers are often accompanied by social stigma, personal shame, and guilt. While there is a significant body of research examining depression in this cancer population, there are still several …

Geographic Trends Of Tobacco-Related Cancers In Cyprus, Evi A. Farazi, Lina Lander, Pavlos Pavlou, Katherine Watkins, Lynne Le, Amr Soliman

Journal Articles: Epidemiology

BACKGROUND: Causal relationships have been previously established between smoking and various cancers. In Cyprus, 39 % of men and 14 % of women reported daily smoking in 2008. The objective of this study was to compare the incidence of tobacco-related cancers to all other cancers by district and rural-urban classification to understand the impact of tobacco in Cyprus.

METHODS: Data on lung, urinary bladder, oral, pharyngeal, head/neck, and laryngeal cancers were obtained from the Cyprus Cancer Registry (1998-2008). There were 3,635 patients with tobacco-related cancers and 18,780 with non-tobacco cancers. Univariate analysis comparing tobacco-related cancers and all other cancers were …

Cancer Trends And Risk Factors In Cyprus, Evi A. Farazi

Journal Articles: Epidemiology

Cyprus, a European Union member state, is a small island in the Mediterranean with a population approaching 900,000 people. Cancer is the second leading cause of death; more therapeutic options for any patient with the disease are available in a central oncology centre in the capital of the island (Nicosia) and fewer therapeutic options (e.g. chemotherapy and hormone therapy only) in a few other public hospitals. Palliative care is offered in several hospices and hospitals, although the field needs improvement. With regards to screening, a national breast cancer screening programme has been in place countrywide since 2007 and is offered …
