Age-Induced Changes In Anti-Tumor Immunity Alter The Tumor Immune Infiltrate And Impact Response To Immuno-Oncology Treatments, Suzanne I Sitnikova, Jennifer A Walker, Laura B Prickett, Michelle Morrow, Viia E Valge-Archer, Matthew J Robinson, Robert W Wilkinson, Simon J Dovedi

Faculty, Staff and Student Publications

INTRODUCTION: Immuno-oncology (IO) research relies heavily on murine syngeneic tumor models. However, whilst the average age for a cancer diagnosis is 60 years or older, for practical purposes the majority of preclinical studies are conducted in young mice, despite the fact that ageing has been shown to have a significant impact on the immune response.

METHODS: Using aged (60-72 weeks old) mice bearing CT26 tumors, we investigated the impact of ageing on tumor growth as well as the immune composition of the tumor and peripheral lymphoid organs.

RESULTS: We found many differences in the immune cell composition of both the …

Effectiveness Of Cognitive Behavioral Therapy Versus Therapeutic Play For Hospitalized Children Diagnosed With Cancer: An Integrative Systematic Review, Dianne Kong

Theses and Dissertations

Psychotherapy provides essential coping mechanisms and strategies for children who are diagnosed with cancer, as they experience the extraordinary burden of physical, emotional, and mental strains. While many medical advancements have been made within the past few decades, progress related to psychotherapy for pediatric cancer patients has not been commensurate, evidenced by the limited current literature. Given the sparsity of relevant research, it is presently difficult to compare and evaluate the various psychotherapeutic interventions available for pediatric oncology patients. Additionally, there are significant challenges in providing psychotherapeutic care for patients and their families, including lack of consistency, disruption of care, …

Addressing Death Distress In Caregivers Of Patients With Malignant Glioma, Kelcie D. Willis

Theses and Dissertations

The field of psychosocial oncology seeks to improve the quality of life of patients and families affected by cancer. This task becomes increasingly important when there are limited, non-curative treatment options, a high probability of recurrence, and rapid functional decline, such as in the case of a malignant glioma (MG). Indeed, the diagnosis of a MG is associated with negative sequalae that often translates to higher caregiver burden. Caregivers—who must manage the functional decline of the patient, changes within the family, and a complicated medical system—often feel overwhelmed, isolated, and ill-equipped to handle these myriad responsibilities. While they also report …

Characterization And Investigation Of Cold Atmospheric Plasma And Its Effects On Cancer Cell Biology, Thomas M. Ritrosky

Theses and Dissertations

Modern cancer treatment uses radiation therapy in over 50% of patient cases. It is an e↵ective way of treating tumors because the mechanisms of cell killing are well known through the damage that ionizing radiation does to DNA. The amount of radiation can be tracked through measuring the dose of the clinical photon or electron beam used. However, there are limitations in the usage of radiation therapy, for example, a tumor can create hypoxic areas that become radioresistant leading to complete ine↵ectiveness of further radiation treatment. This project looks into the application of cold atmospheric plasma as an adjuvant therapy …

Characterizing The Effects Of Antiandrogens And Senolytics To Enhance The Therapeutic Response To Castration-Resistant Prostate Cancer, Justin M. Silverman

Theses and Dissertations

Prostate cancer is the most frequently diagnosed cancer in males and the second most common cause of cancer deaths. Androgen deprivation therapy, whether through surgical or chemical castration, is the mainstay for treatment of advanced prostate cancer; however, despite an initial response, most patients eventually develop a progressive PSA rise, and castration- sensitive prostate cancer gives rise to castration-resistant prostate cancer. The standard of care therapy includes the antiandrogens such as enzalutamide and abiraterone acetate as well as the microtubule poison, docetaxel, and various immunotherapies; however, while prostate cancer research is progressing, there continues to be a compelling need for …

This infrastructure enables researchers to mine novel associations and gather relevant knowledge for personalized clinical outcomes.

The dissertation discusses the design framework and implementation of HINGE, which abstracts structured data from treatment planning systems, treatment management systems, and electronic health records. It utilizes …

Methodological Considerations In Pisces 3: A Randomized, Placebo-Controlled Study Of Intracerebral Stem Cells In Subjects With Disability Following An Ischemic Stroke, Daniel T Laskowitz, Keith W Muir, Sean I Savitz, Lawrence R Wechsler, Julie G Pilitsis, Scott Y Rahimi, Richard L Beckman, Vincent Holmes, Peng R Chen, Laura Juel, Deborah Koltai, Brad J Kolls

Faculty, Staff and Student Publications

Background and hypothesis: At present, there are no medical interventions proven to improve functional recovery in patients with subacute stroke. We hypothesize that the intraparenchymal administration of CTX0E03, a conditionally immortalized neural stem cell line, linked with a standardized rehabilitation therapy regimen for the upper limb, would improve functional outcomes in patients 6-12 months after an index ischemic stroke.

Study design: PISCES III was designed as a multicenter prospective, sham-controlled, outcome-blinded randomized clinical trial. Eligibility required a qualifying ischemic stroke 6-12 months prior to surgical intervention. Patients must be between 35 and 75 years of age and have residual moderate …

Promoting Healthier Treatment Outcomes In Obese Cancer Patients Taking High Dose Methotrexate, Carly Dell'ova

Walden Dissertations and Doctoral Studies

Cancer and obesity rates continue to rise, creating enormous public heath burdens to the individual and at the national and global levels, reducing quality of life, and increasing spending. Moreover, the relationships between cancer and obesity are not well understood. A commonly used chemotherapy for several types of cancer is high dose methotrexate (HDMTX). Along with chemotherapy, especially at high doses, comes toxicity to specific organs and the entire body. However, limited research has been conducted on obese cancer patients as they are often excluded from clinical studies. Practitioners need to better understand how to dose these patients to provide …

Oncology Nurses, Compassion Fatigue And General Health: A Mixed-Methods Study, Michelle Rampersad

Walden Dissertations and Doctoral Studies

Current literature on compassion fatigue is expansive, but there is a lack on the relationship between compassion fatigue and general health complaints in oncology nurses; how they perceive compassion fatigue and its relation to their general health. Using Pender’s health promotion model, this mixed methods study addressed how oncology nurses perceive compassion fatigue and whether a correlation exists between compassion fatigue and general health complaints. Data were collected from a sample of 55 oncology nurses through two separate Survey Monkey links. All 55 participants completed quantitative data points including a demographic questionnaire, the Professional Quality of Life 5 tool, and …

A Nursing Staff Education Module On Survivorship Care Plans In Primary Care, Janette Francis

Walden Dissertations and Doctoral Studies

Survivorship care plans (SCPs) bridge the gap in the transition of care from oncology to primary care providers (PCPs) for breast cancer survivors. Despite strong recommendations for SCPs, their use remains limited. Guided by Knowles’ adult learning theory, the project focused on, first, determining whether a predeveloped staff education activity was valid using the Lynn model criteria for validation. Second, if in a rural clinic where SCP were not consistently used providers, nurses, and staff knowledge regarding the importance of SCP would increase following an educational program. An expert panel of 5 educational experts validated the educational module for appropriateness …

Factors Impacting College Students’ Receipt Of Human Papillomavirus Vaccination, Joy Yvette Payne

Walden Dissertations and Doctoral Studies

Less than half of U. S. students entering college have had a human papillomavirus (HPV) vaccination, placing them at risk for HPV-related cancers. This study’s purpose was to identify predictors of HPV vaccination initiation in college students. Andersen’s behavioral model of health services use was used to examine the differences in predisposing, enabling, and need factors in U.S. college students ages 18–26 years who received an initial HPV vaccination in college compared to those who never received an HPV vaccination. The study was a quantitative, cross-sectional survey design using multivariable logistic regression for data analyses. Data were collected through an …

Testing The Efficacy And Synergistic Components Of Sesamol And Black Rice Extract On Human Colon Cancer Cells, Sera Lim, Philip M. Gerk

UROP Posters

Purpose: Systemic treatment of colorectal cancer involves chemotherapeutic agents which elicit serious and negative side effects from the toxicity of the drug. To address this issue, we are testing dietary supplements for their efficacy against human colon cancer cell lines and also their potential synergistic effects when combined with conventional chemotherapy. Dietary supplements (specifically sesamol and black rice extract) exhibit anticancer, anti-inflammatory, and chemo-preventive properties. Meanwhile, one of the cancer resistance mechanisms is the upregulation of drug elimination mechanisms, leading to multi-drug resistance. We hypothesize that dietary compounds will act as chemo-enhancers, thus enhancing potency of the chemotherapy drug(s) on …

Novornabreak: Local Assembly For Novel Splice Junction And Fusion Transcript Detection From Rna-Seq Data, Yukun Tan, Vakul Mohanty, Shaoheng Liang, Jinzhuang Dou, Jun Ma, Kun Hee Kim, Marc Jan Bonder, Xinghua Shi, Charles Lee, Zechen Chong, Ken Chen

Faculty, Staff and Student Publications

We present novoRNABreak, a unified framework for cancer specific novel splice junction and fusion transcript detection in RNA-seq data obtained from human cancer samples. novoRNABreak is based on a local assembly model, which offers a tradeoff between the alignment-based and de novo whole transcriptome assembly (WTA) methods. This approach is accurate and sensitive in assembling novel junctions that are difficult to directly align or have multiple alignments. Additionally, it is more efficient due to the strategy that focuses on junctions rather than full length transcripts. The performance of novoRNABreak is demonstrated by a comprehensive set of experiments using synthetic data …

Faculty, Staff and Student Publications

Purpose: The clinical management of brain metastases after stereotactic radiosurgery (SRS) is difficult, because a physician must review follow-up magnetic resonance imaging (MRI) scans to determine treatment outcome, which is often labor intensive. The purpose of this study was to develop an automated framework to contour brain metastases in MRI to help treatment planning for SRS and understand its limitations.

Methods and materials: Two self-adaptive nnU-Net models trained on postcontrast 3-dimensional T1-weighted MRI scans from patients who underwent SRS were analyzed. Performance was evaluated by computing positive predictive value (PPV), sensitivity, and Dice similarity coefficient (DSC). The training and testing …

Pathologic And Molecular Insights In Nodal T-Follicular Helper Cell Lymphomas, Mario L Marques-Piubelli, Catalina Amador, Francisco Vega

Faculty, Staff and Student Publications

T-follicular helper (TFH) cells are one of the T-cell subsets with a critical role in the regulation of germinal center (GC) reactions. TFH cells contribute to the positive selection of GC B-cells and promote plasma cell differentiation and antibody production. TFH cells express a unique phenotype characterized by PD-1hi, ICOShi, CD40Lhi, CD95hi, CTLAhi, CCR7lo, and CXCR5hi . Three main subtypes of nodal TFH lymphomas have been described: 1) angioimmunoblastic-type, 2) follicular-type, and 3) not otherwise specified (NOS). The diagnosis of these neoplasms can be challenging, and it is rendered based on a combination of clinical, laboratory, histopathologic, immunophenotypic, and molecular …

Methods: We used the most recent available data from the May 2019 wave of the nationally-representative Tobacco Use Supplement to the Current Population Survey. The survey weights were used to estimate the national prevalence of individuals who currently smoke among individuals who use menthol and nonmenthol cigarettes. Survey-weighted logistic regression methods were used to estimate the association of menthol cigarette use with formerly smoking cigarettes and attempting to quit within the past …

Applying Ht-Saxs To Chemical Ligand Screening, Chris A Brosey, Runze Shen, Davide Moiani, Darin E Jones, Kathryn Burnett, Greg L Hura, John A Tainer

Faculty, Staff and Student Publications

Chemical probes are invaluable tools for investigating essential biological processes. Understanding how small-molecule probes engage biomolecular conformations is critical to developing their functional selectivity. High-throughput solution X-ray scattering is well-positioned to profile target-ligand complexes during probe development, bringing conformational insight and selection to traditional ligand binding assays. Access to high-quality synchrotron SAXS datasets and high-throughput data analysis now allows routine academic users to incorporate conformational information into small-molecule development pipelines. Here we describe a general approach for benchmarking and preparing HT-SAXS chemical screens from small fragment libraries. Using the allosteric oxidoreductase Apoptosis-Inducing Factor (AIF) as an exemplary system, we illustrate …

Faculty, Staff and Student Publications

Background: Combining immune checkpoint therapy (ICT) and vascular endothelial growth factor inhibitors (VEGFi) may result in increased treatment-related and immune-related adverse events (TRAEs and irAEs) compared to ICT alone. This metanalysis was conducted to identify prospective phase II or III clinical studies that evaluated the toxicity profile of ICT + VEGFi compared to ICT alone.

Methods: A systematic search was performed across all cancer types and major databases until August 10, 2022, and screening was done by two independent investigators. Inclusion criteria included phase 2 or 3 studies with at least one arm of patients treated with combination therapy and …

Cd73-Generated Extracellular Adenosine Promotes Resolution Of Neutrophil-Mediated Tissue Injury And Restrains Metaplasia In Pancreatitis, Baylee J O'Brien, Erika Y Faraoni, Lincoln N Strickland, Zhibo Ma, Victoria Mota, Samantha Mota, Xuebo Chen, Tingting Mills, Holger K Eltzschig, Kathleen E Delgiorno, Jennifer M Bailey-Lundberg

Faculty, Staff and Student Publications

Pancreatitis is currently the leading cause of gastrointestinal hospitalizations in the US. This condition occurs in response to abdominal injury, gallstones, chronic alcohol consumption or, less frequently, the cause remains idiopathic. CD73 is a cell surface ecto‐5′‐nucleotidase that generates extracellular adenosine, which can contribute to resolution of inflammation by binding adenosine receptors on infiltrating immune cells. We hypothesized genetic deletion of CD73 would result in more severe pancreatitis due to decreased generation of extracellular adenosine. CD73 knockout (CD73 −/−) and C57BL/6 (wild type, WT) mice were used to evaluate the progression and response of caerulein‐induced acute and chronic pancreatitis. …

Positron Emission Tomography Derived Metrics In Relapsed Or Refractory Large B-Cell Lymphoma With Residual Disease Before Autologous Stem Cell Transplant, Hua-Jay J Cherng, Guofan Xu, Lei Feng, Raphael Steiner, Luis Fayad, Paolo Strati, Ranjit Nair, Loretta J Nastoupil, Hun Ju Lee, Sattva S Neelapu, Christopher R Flowers, Maria Rodriguez, Michael Wang, Fredrick Hagemeister, Chelsea C Pinnix, Jeremy Ramdial, Samer Srour, Yago Nieto, Katayoun Rezvani, Richard Champlin, Partow Kebriaei, Jason Westin, Homer A Macapinlac, Elizabeth Shpall, Sairah Ahmed

Salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) is a potentially curative treatment for patients with relapsed or refractory large B-cell lymphoma (rrLBCL) with chemosensitive disease. A18 F-fluorodeoxyglucose positron emission tomography (PET) scan after salvage chemotherapy is used to assess response and eligibility for ASCT, but metrics for chemosensitivity in patients with residual disease are not well defined. We performed a single-centre retrospective analysis of 92 patients with a partial response or stable disease after salvage chemotherapy for rrLBCL who received ASCT to investigate PET-derived parameters and their prognostic utility. The Deauville 5-point Scale (D-5PS) score, …

The Kynurenine Pathway Presents Multi-Faceted Metabolic Vulnerabilities In Cancer, Ricardo A León-Letelier, Rongzhang Dou, Jody Vykoukal, Ali Hussein Abdel Sater, Edwin Ostrin, Samir Hanash, Johannes F Fahrmann

Faculty, Staff and Student Publications

The kynurenine pathway (KP) and associated catabolites play key roles in promoting tumor progression and modulating the host anti-tumor immune response. To date, considerable focus has been on the role of indoleamine 2,3-dioxygenase 1 (IDO1) and its catabolite, kynurenine (Kyn). However, increasing evidence has demonstrated that downstream KP enzymes and their associated metabolite products can also elicit tumor-microenvironment immune suppression. These advancements in our understanding of the tumor promotive role of the KP have led to the conception of novel therapeutic strategies to target the KP pathway for anti-cancer effects and reversal of immune escape. This review aims to 1) …

Impact Of Region-Of-Interest Size On Immune Profiling Using Multiplex Immunofluorescence Tyramide Signal Amplification For Paraffin-Embedded Tumor Tissues, Baohua Sun, Caddie Laberiano-Fernández, Ruth Salazar-Alejo, Jiexin Zhang, Jose Luis Solorzano Rendon, Jack Lee, Luisa Maren Solis Soto, Ignacio Ivan Wistuba, Edwin Roger Parra

Faculty, Staff and Student Publications

Introduction: Representative regions of interest (ROIs) analysis from the whole slide images (WSI) are currently being used to study immune markers by multiplex immunofluorescence (mIF) and single immunohistochemistry (IHC). However, the amount of area needed to be analyzed to be representative of the entire tumor in a WSI has not been defined.

Methods: We labeled tumor-associated immune cells by mIF and single IHC in separate cohorts of non-small cell lung cancer (NSCLC) samples and we analyzed them as whole tumor area as well as using different number of ROIs to know how much area will be need to represent the …
