The coronavirus disease 2019 (COVID-19) pandemic has produced a new global challenge for patients with cancer. The disease and the immunosuppression induced by cancer therapies have generated a perfect storm of conditions to increase the severity of the symptoms and worsen the prognosis. However, a few clinical reports showcased the power of viruses to induce remission in some patients suffering from liquid tumors. Here, we reviewed six cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that resulted in cancer remission, simultaneously highlighting the strengths and the unique challenges of oncolytic virotherapy. Virotherapy has become a special case of cancer …

Advances in Clinical Medical Research and Healthcare Delivery
The development and widespread use of immune checkpoint inhibitors (ICIs) have advanced the field of oncology in a short period of time. Despite this, patient perception regarding this new medication class has not been adequately assessed, which may affect treatment decisions and adherence. The Belief about Medicines Questionnaire (BMQ) is a validated survey composed of 18 questions which analyzes patient’s beliefs about the necessity of prescribed medication and concern about the potential adverse events caused by the medication. General medication overuse and harm are also determined. This is the first study to utilize the BMQ for patients on ICI therapy.

Health Policy & Community Health: Faculty Publications
Poor air quality and environmental pollution remain some of the main etiological factors leading to cancers and cancer-related deaths worldwide. As a result of human activities, deleterious airborne chemicals can be dispersed not only in the environment but also released in occupational environments and industrial areas. Air pollutants and cancer links are now established through various oxidative stress-related mechanisms and related DNA damages. Generally, ambient and indoor air pollutants have been understudied in sub-Saharan Africa (SSA) compared to other regions in the world. Our study not only highlights the deleterious effects of air pollutants in these developing countries, but it …

Can Statins Lessen The Burden Of Virus Mediated Cancers?, Eva H Clark, Sarah T Ahmed, Elaine Chang, Elizabeth Y Chiao, Donna L White
Center for Medical Ethics and Health Policy Staff Publications
Background: Oncogenic viruses, including hepatitis B virus (HBV), hepatitis C virus (HCV), human papillomavirus (HPV), Epstein Barr virus (EBV), and Kaposi Sarcoma Herpes virus (KSHV) contribute to a significant proportion of the world's cancers. Given the sizeable burden of virus mediated cancers, development of strategies to prevent and/or treat these cancers is critical. While large population studies suggest that treatment with hydroxymethylglutaryl-CoA reductase inhibitors, commonly known as statins, may reduce the risk of many cancer types including HBV/HCV related hepatocellular carcinoma, few studies have specifically evaluated the impact of statin use in populations at risk for other types of virus …

The lack of genetically diverse preclinical animal models in basic biology and efficacy testing has been cited as a potential cause of failure in clinical trials. We developed and characterized five diverse RAG1 null mouse strains as models that allow xenografts to grow. In these strains, we characterized the growth of breast cancer, leukemia and glioma cell lines. We found a wide range of growth characteristics that were far more dependent on strain than tumor type. For the breast cancer cell line, we characterized the spectrum of xenograft/tumor growth at structural, histological, cellular and molecular levels across each strain, and …

Comprehensive understanding of cancer-specific survival differences in gender is critical for cancer prevention and treatment. Based on the Surveillance Epidemiology and End Results database, we included data from the most prevalent cancers (lung, esophageal, liver, pancreatic, stomach, colorectal, kidney, and bladder cancer). Cox proportional hazards regression models were constructed to estimate hazard ratios, simultaneously adjusting for demographic, clinical, and treatment factors. Overall, male patients had a worse cancer-specific survival than female patients. After adjustment for cancer prevalence with 1:1 matching, gender remained a significant factor in cancer-specific survival. Among the included cancer types, female patients showed survival benefit in lung, …

Purpose: Cancer is one of the leading causes of mortality and morbidity, and therefore, tremendous research work is continuously being done around the world with consideration of etiopathogenesis as well as identification of therapeutic targets. Decades of continuous war in Afghanistan has left the medical infrastructure of the country in a miserable situation. There is a serious deficiency in research work in the fields of pathology and oncology at the moment with minimal data available to elaborate about the demographic characteristics of various malignant disorders in the country, which would be indispensable to pave the way for further research and …
Relieving Immune Suppression In The Melanoma Tumor Microenvironment, Gretel Torres Santiesteban
Relieving Immune Suppression In The Melanoma Tumor Microenvironment, Gretel Torres Santiesteban
Dartmouth College Ph.D Dissertations
The high immunogenicity of melanoma tumors makes these malignancies an attractive target for immunotherapeutic treatment, as evidenced by the success of ipilimumab and nivolumab. However, most immunotherapeutic approaches have had limited success, partly due to the suppression of innate and adaptive immune responses by tumor-associated macrophages (TAMs) in the tumor microenvironment (TME). TAM redirection may relieve immunosuppression in the TME, directly inhibiting melanoma growth and potentially enhancing the efficacy of additional targeted and immuno-therapies.
We have shown that synthetic oleanane triterpenoid CDDO-Me (or C-Me) enhances immune activation in the melanoma TME by reprogramming TAMs from immunosuppressive to immunostimulatory. CDDO-Me is …
The Lived Experiences Of Middle Eastern Immigrant Women During Their Cancer Survivorship Journey: A Phenomenological Study, Enam Alsrayheen, Khaldoun Aldiabat, Catherine Aquino-Russell
The Lived Experiences Of Middle Eastern Immigrant Women During Their Cancer Survivorship Journey: A Phenomenological Study, Enam Alsrayheen, Khaldoun Aldiabat, Catherine Aquino-Russell
The Qualitative Report
The number of Middle Eastern immigrant women (MEIW) living in Canada has significantly increased. However, this group of women is underrepresented in health research and there is a gap in knowledge of their cancer survivorship experiences in Canada. This phenomenological qualitative approach was employed to uncover the meaning of the lived experiences of MEIW during their cancer survivorship journey (CSJ). Data were collected through unstructured interviews and one written description from three MEIW. The participants' perspectives of cancer risk factors were believed to be the cause of their cancer, and their CSJ was fear-inducing and anxiety-provoking. There appears to be …

Student Theses and Dissertations
Cyclase-Associated Protein 1 (CAP1) is an actin-regulating protein that promotes actin dynamics and is also involved in cell adhesion and proliferation as well as implicated in human cancers. We previously found that phosphorylation at the Ser307/Ser309 tandem regulatory site on CAP1 is critical for CAP1 functions in breast and pancreatic cancer cells. We silenced CAP1 through RNAi in HCT116 and SW480 colon cancer cells as confirmed in Western blotting. We have found that depletion of CAP1 led to reduced FAK (Focal Adhesion Kinase) activity and matrix adhesion in SW480 cells, while it stimulated FAK activity and cell adhesion in HCT116 …

MicroRNAs (miRNAs) are non-protein-coding RNA molecules 20-25 nucleotides in length that can suppress the expression of genes involved in numerous physiological processes in cells. Accumulating evidence has shown that dysregulation of miRNA expression is related to the pathogenesis of various human diseases and cancers. Thus, stragegies involving either restoring the expression of tumor suppressor miRNAs or inhibiting overexpressed oncogenic miRNAs hold potential for targeted cancer therapies. However, delivery of miRNAs to tumor tissues is a challenging task. Recent advances in nanotechnology have enabled successful tumor-targeted delivery of miRNA therapeutics through newly designed nanoparticle-based carrier systems. As a result, miRNA therapeutics …

A Microfluidics-Based Approach For Isolation Of Antigen-Specific Cd8+ T Cells, Meredith Frank
Dissertations and Theses (Open Access)
Cancer is a global epidemic: there are predicted to be 200 million new cases this year alone. Almost a quarter of all cancer-related deaths are caused by lung cancer, for which 5-year survival rates are just above 20%. 85% of lung cancer diagnoses are classified as non-small cell lung cancer (NSCLC) for which 5-year survival rates in metastatic disease are less than 10%. Early detection and targeted therapies have improved prognoses, yet relapse is still common among patients.
Immunotherapies that leverage tumor-specific CD8+ cytotoxic T cells have shown great promise for the treatment of NSCLC. However, although highly promising, …

Defining The Cooperation Between Mhc-I And Mhc-Ii Neoantigen-Driven T Cell Responses To Develop Effective Personalized Immunotherapies, Charmelle Williams
Dissertations and Theses (Open Access)
Immune checkpoint therapy (ICT) (e.g. anti-CTLA-4 (α-CTLA-4), anti-PD-1 (α-PD-1)) enables durable T cell-dependent anti-tumor immunity in certain cancer patients. Since a subset of patients respond to ICT, this work aims at developing a more in-depth understanding of T-cell responses to MHC class I (MHC-I) and MHC class II (MHC-II) tumor antigens that are derived from aberrant expression of non-mutant antigens or driver and passenger somatic alterations that can function as tumor neoantigens. We used a poorly immunogenic Brafv600e Pten-/- Cdkn2a-/- YUMM1.7 (Y1.7) murine melanoma line with a paucity of endogenous neoantigens that is unresponsive to ICT, and …

PURPOSE: Adolescent and young adult (AYA) cancer survivors experience greater functional deficits compared to non-cancer peers or older survivors with a similar diagnosis. Physical activity (PA) is a key strategy for mitigating functional decline, and motivation and peer support are critical PA facilitators in AYA cancer survivors. Active video games (AVGs) may be a "gateway" method to promote PA. Further, integrating AVGs into group videoconferencing, a medium used by AYAs to socialize, can capitalize on peer support needed for PA motivation. Thus, we examined the use of AVGs and/or videoconferencing in PA interventions that included AYA survivors and the effect …

Trends Of Human Papilloma Virus- Related Cancers And Hpv Vaccination In Nebraska From 2010 To 2018, Christelle Massumbu
Capstone Experience: Master of Public Health
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 …

Faculty, Staff and Students Publications
Protein post-translational modifications (PTMs) profoundly influence protein functions and play crucial roles in essentially all cell biological processes. The diverse realm of PTMs and their crosstalk is linked to many critical signaling events involved in neoplastic transformation, carcinogenesis and metastasis. The pathological roles of various PTMs are implicated in all aspects of cancer hallmark functions, cancer metabolism and regulation of tumor microenvironment. Study of PTMs has become an important area in cancer research to understand cancer biology and discover novel biomarkers and therapeutic targets. With a limited scope, this review attempts to discuss some PTMs of high frequency with recognized …

Osteosarcoma is a primary malignant bone tumor arising from bone-forming mesenchymal cells in children and adolescents. Despite efforts to understand the biology of the disease and identify novel therapeutics, the survival of osteosarcoma patients remains dismal. We have concurrently profiled the copy number and gene expression of 226 osteosarcoma samples as part of the Strategic Partnering to Evaluate Cancer Signatures (SPECS) initiative. Our results demonstrate the heterogeneous landscape of osteosarcoma in younger populations by showing the presence of genome-wide copy number abnormalities occurring both recurrently among samples and in a high frequency. Insulin growth factor receptor 1 (IGF1R) is a …

Glioblastoma is one of the most aggressive types of cancer with success of therapy being hampered by the existence of treatment resistant populations of stem-like Tumour Initiating Cells (TICs) and poor blood-brain barrier drug penetration. Therapies capable of effectively targeting the TIC population are in high demand. Here, we synthesize spherical diketopyrrolopyrrole-based Conjugated Polymer Nanoparticles (CPNs) with an average diameter of 109 nm. CPNs were designed to include fluorescein-conjugated Hyaluronic Acid (HA), a ligand for the CD44 receptor present on one population of TICs. We demonstrate blood-brain barrier permeability of this system and concentration and cell cycle phase-dependent selective uptake …

Whole-organ mapping was used to study molecular changes in the evolution of bladder cancer from field effects. We identified more than 100 dysregulated pathways, involving immunity, differentiation, and transformation, as initiators of carcinogenesis. Dysregulation of interleukins signified the involvement of inflammation in the incipient phases of the process. An aberrant methylation/expression of multiple HOX genes signified dysregulation of the differentiation program. We identified three types of mutations based on their geographic distribution. The most common were mutations restricted to individual mucosal samples that targeted uroprogenitor cells. Two types of mutations were associated with clonal expansion and involved large areas of …
Doubling Down On Sepsis: A Quality Improvement Project To Improve Sepsis Bundle Compliance On An Inpatient Oncology Unit, Kayla Slay
Dissertations
Problem: Sepsis is a leading cause of death worldwide, and the second most common cause of death in cancer patients. Early management of sepsis through use of sepsis bundles have been shown to improve patient outcomes, yet bundle adherence is unfortunately inconsistent.
Methods: A two-nurse team, called the Sepsis Sidekicks, was a process improvement initiative to increase compliance with the center for Medicare and Medicaid Services (CMS) sepsis bundle and improve patient outcomes related to sepsis. The observational quality improvement project utilized a Plan-Do-Study-Act (PDSA) model over a six-week period where quantitative data was collected using a retrospective chart review. …

Medicinal Plants And Herbs For Cancer Prevention, Madeline Mctigue, Julianna Goelzer, William Ranahan
Research Symposium
Modern medicine has yet to produce selective treatments for the vast majority of cancer types. Most chemotherapies, though complex, remain non-specific, and thus destroy healthy cells. Over 25% of cancer patients die from the effects of chemotherapy before the actual tumor would have progressed to the point of organismal death (Megget 2008).
