The main objective is to find variants that may affect an individual's response to a given medication. The implementation of pharmacogenomics in oncology facilitates informed decision-making by clinicians in drug selection and dosage determination.
Analyzing Prominent Genes In Acute Lymphocytic Leukemia (All), Shima Z. Omar
Analyzing Prominent Genes In Acute Lymphocytic Leukemia (All), Shima Z. Omar
Honors College Theses
Acute lymphocytic leukemia (ALL) is the most common type of childhood cancer. Leukemia is a type of cancer that involves the bone marrow and blood. This research study examined prominent genes in the disease. Two groups of genes, tumor suppressor and cell differentiation, were compared using statistical analysis to compare their binding potential and epigenetic potential. It is most likely that I failed to detect significant differences either because these genes’ function in the disease etiology is not strongly contexed to changes in expression, or that the magnitude of the differences were too slight to be detected with these methods. …
Distinct Nrf2 Signaling Thresholds Mediate Lung Tumor Initiation And Progression, Janine M. Deblasi
Distinct Nrf2 Signaling Thresholds Mediate Lung Tumor Initiation And Progression, Janine M. Deblasi
USF Tampa Graduate Theses and Dissertations
NRF2 is a redox-responsive transcription factor the directs the antioxidant program and several critical metabolic processes. Mutations in NRF2 or its negative regulator KEAP1 occur in up to one third of non-small cell lung cancers (NSCLCs) and are often associated with resistance to therapy and poor outcomes. In the present studies, murine alleles of the Keap1 and Nrf2 mutations found in human NSCLC were developed and I comprehensively investigated their impact on tumor initiation and progression. I observed that chronic Nrf2 stabilization by Keap1 loss-of-function or Nrf2 activating mutation was not sufficient to cause lung tumor initiation, even when p53 …

Chemistry & Biochemistry Theses & Dissertations
Cancer continues to be the leading global cause of death, with challenges in early diagnosis, drug resistance, non-specific drug targeting, and cancer recurrence and metastasis posing formidable obstacles in cancer therapy. In this context, Prostate Apoptosis Response-4 (Par-4), a pro-apoptotic tumor suppressor protein, emerged as a promising therapeutic target due to its ability to selectively induce apoptosis in cancer cells, thereby minimizing the drug-associated adverse effects. However, a comprehensive understanding of the structural features of Par-4, specifically the caspase-cleaved fragment (cl-Par-4), is crucial for therapeutic advancements.
This dissertation investigated the effects of various ions, both monovalent and divalent, on the …

About Dying And Death: Thanatology's Place In Medical Curriculum, Jill Dombroski
About Dying And Death: Thanatology's Place In Medical Curriculum, Jill Dombroski
Electronic Thesis and Dissertation Repository
This study explored how healthcare providers engage in advance care planning and end-of-life care conversations. The research explored what shapes their understanding and the extent to which concepts from thanatology they intuitively bring in, explicitly bring in, and maybe fail to recognize. To achieve this, constructivist grounded theory (CGT) methodology guided the design, data collection, analysis, and interpretation of the findings, which allowed for iteration across interviews and analysis with existing theories and data in the literature. The CGT design encouraged further engagement with the literature in an ongoing iterative fashion as well as with the analysis of the data. …
Role Of Ripk3 In The Pathogenesis Of Tet2 Mutant Hematopoietic Malignancies, Kanak Joshi
Role Of Ripk3 In The Pathogenesis Of Tet2 Mutant Hematopoietic Malignancies, Kanak Joshi
Dissertations
Hematopoiesis is dynamically controlled by an epigenetic landscape that regulates gene transcription. Ten-eleven translocation 2 (TET2) is a Fe2+ and α-ketoglutarate (α-KG)-dependent dioxygenase that regulates the transcriptional status of genes associated with hematopoietic stem cell self-renewal and multiple stages of lineage commitment and differentiation. TET2 mutations are commonly detected in almost all types of hematopoietic malignancies, including myeloproliferative disorder, acute myeloid leukemia, and peripheral T-cell lymphomas. In most cases, TET2 is a founder mutation that occurred in hematopoietic stem/progenitor cells (HSPCs). The mutant HSCs undergo clonal expansion and evolution with the accumulation of additional mutations for malignant transformation. Microbial-stimulated inflammatory …
A Quantitative Visualization Tool For The Assessment Of Mammographic Risky Dense Tissue Types, Margaret R. Mccarthy
A Quantitative Visualization Tool For The Assessment Of Mammographic Risky Dense Tissue Types, Margaret R. Mccarthy
Electronic Theses and Dissertations
Breast cancer is the second most occurring cancer type and is ranked fifth in terms of mortality. X-ray mammography is the most common methodology of breast imaging and can show radiographic signs of cancer, such as masses and calcifcations. From these mammograms, radiologists can also assess breast density, which is a known cancer risk factor. However, since not all dense tissue is cancer-prone, we hypothesize that dense tissue can be segregated into healthy vs. risky subtypes. We propose that risky dense tissue is associated with tissue microenvironment disorganization, which can be quantified via a computational characterization of the whole breast …
Dosimetric Evaluation Of Left-Sided Chest Wall Vmat Treatment With And Without Jaw Tracking; Dose Comparison Of Left Anterior Descending Artery Versus Heart Mean Dose, Jacqueline J. Emus
Dosimetric Evaluation Of Left-Sided Chest Wall Vmat Treatment With And Without Jaw Tracking; Dose Comparison Of Left Anterior Descending Artery Versus Heart Mean Dose, Jacqueline J. Emus
Culminating Experience Projects
Radiation therapy has significantly improved breast cancer survival rates; however, it can still lead to long-term side effects, particularly affecting the heart. Left-side breast cancer patients face higher risks due to the proximity of the heart to the treatment area. To mitigate cardiac toxicity, various strategies, including jaw tracking and Volumetric Modulated Arc Therapy (VMAT), have been proposed. This study investigates the dosimetric impact of VMAT plans with and without jaw tracking on the left anterior descending artery (LAD) dose and heart mean dose in post-mastectomy breast cancer patients. Ten patients previously treated with VMAT were evaluated, and the results …

Auto-Segmentation In Pancreatic And Liver Radiation Therapy, Cenji Yu
Dissertations & Theses (Open Access)
Background
Gastrointestinal cancers exhibit a high mortality rate compared to other cancer types. Among these, pancreatic cancer ranks as the fourth leading cause of cancer-related deaths worldwide. The five-year survival rate remains alarmingly low at a mere 9%. Hepatocellular carcinoma (HCC), another aggressive form of cancer, is rapidly becoming the primary cause of cancer-related deaths in the United States. The treatment of both liver cancer and pancreatic cancer heavily relies on a multidisciplinary approach. Innovative treatment strategies involving dose-escalated regimens, such as stereotactic body radiation therapy (SBRT), are emerging as an important pillar of the management of liver and pancreatic …
An Existential Punchline: How Humor Functions In A Young Adult Friendship Facing Advanced Cancer, Megan E. Solberg
An Existential Punchline: How Humor Functions In A Young Adult Friendship Facing Advanced Cancer, Megan E. Solberg
Electronic Theses and Dissertations
Young adults (i.e., age 18-39) only comprise 4% of the total cancer population, yet cancers in this group are commonly found at more advanced stages due to situational factors influencing delayed diagnosis including access to healthcare, quality health insurance and competing life demands that may hinder prioritization of healthcare. Young adults with cancer also face unique challenges including higher rates of psychological distress, which may contribute to increased risk of social disconnection in response to cancer. Research suggests that humor may be a helpful coping approach and communication mechanism for mitigating distress and discussing difficult topics. Grounded within the frameworks …
The Development Of Artificial Intelligence-Based Tools For Expert Peer Review Of Radiotherapy Treatment Plans, Mary Gronberg
The Development Of Artificial Intelligence-Based Tools For Expert Peer Review Of Radiotherapy Treatment Plans, Mary Gronberg
Dissertations & Theses (Open Access)
Creating a patient-specific radiation treatment plan is a time-consuming and operator-dependent manual process. The treatment planner adjusts the planning parameters in a trial-and-error fashion in an effort to balance the competing clinical objectives of tumor coverage and normal tissue sparing. Often, a plan is selected because it meets basic organ at risk dose thresholds for severe toxicity; however, it is evident that a plan with a decreased risk of normal tissue complication probability could be achieved. This discrepancy between “acceptable” and “best possible” plan is magnified if either the physician or treatment planner lacks focal expertise in the disease site. …
Risk And Risk Factors For Colorectal Subsequent Malignancies In Survivors Of Childhood Cancer: A Report From The Childhood Cancer Survivor Study, Constance A. Owens
Risk And Risk Factors For Colorectal Subsequent Malignancies In Survivors Of Childhood Cancer: A Report From The Childhood Cancer Survivor Study, Constance A. Owens
Dissertations & Theses (Open Access)
Survivors of childhood cancer are at risk for colorectal subsequent malignant neoplasms (SMNs); notably, these cancers are amenable to screening. To identify at-risk survivors that may benefit from early screening, descriptive and risk factor analyses were performed to ascertain risk factors for colorectal SMN in childhood cancer survivors. In particular, we explored detailed radiation therapy (RT) data – colorectal and substructure dose-volume metrics – as risk factors for colorectal SMN risk; metrics that have yet to be thoroughly investigated. We developed a novel population-based anatomical colorectal model with substructures for RT dosimetry in late effects studies of childhood cancer survivors; …
A Comparison Of Hypofractionated Radiation Therapy Breast Plans For Large Breasted Patients - Hybrid 3d Conformal, And Volumetric Modulated Arc Therapy Vs Standard Hypofractionated 3d Conformal, Kelsie Wentland
Culminating Experience Projects
Abstract
Introduction
Patients with a large breast volume are more at risk of adverse skin effects with radiation therapy. Studies concerning these patients are very limited, especially in regard to comparison of planning techniques. While traditional tangent 3D conformal radiation therapy has been the standard of care, recent literature has shown possible benefits of hybrid planning for average breast volume patients. Little has been studied regarding breast cancer patients with large breast volumes and the possible benefits of hybrid planning of this patient demographic. Creating a hybrid plan could have the benefits of both different treatment modalities to provide a …

Understanding How Cancer Adapts To Stress And Therapy Using Evolutionary Game Theory, Mariyah Pressley
USF Tampa Graduate Theses and Dissertations
Adaptive responses in cancer promote disease initiation, progression, and resistance to treatment. Understanding the underlying evolutionary dynamics behind these adaptive responses is crucial for developing effective therapeutic strategies. Evolutionary game theory (EGT) has proven a useful tool in analyzing how different cellular behaviors and evolutionary forces shape the dynamics of tumor growth, response to therapy, and the emergence of resistance. In this dissertation, we utilize EGT to understand the adaptive responses of cancer through the lens of ecology and evolution. By employing fitness-generating models and exploring various ecological contexts, we aimed to unveil critical factors influencing aggressive cell phenotypes, treatment …
Withaferin A And Immune Checkpoint Blocker Therapy For The Treatment Of Non-Small Cell Lung Cancer, Roukiah Khalil
Withaferin A And Immune Checkpoint Blocker Therapy For The Treatment Of Non-Small Cell Lung Cancer, Roukiah Khalil
USF Tampa Graduate Theses and Dissertations
Lung cancer is the first cause of cancer-related deaths in both men and women with an overall five-year survival rate of 28%. Although immune checkpoint blockers (ICBs) are currently FDA-approved for the treatment of non-small cell lung cancer (NSCLC), only 17-20% of patients achieve durable responses by the induction of immunologic memory. The lack of response in most patients can be attributed to the tumor-intrinsic or tumor-extrinsic immune resistance mechanisms. A biomarker of importance is the Programmed Death Ligand-1 (PD-L1), as higher PD-L1 expression is usually associated with a better response to ICBs. Although studies have attempted to combine ICBs …

Primary Care Providers’ Practices And Attitudes Towards Brca Genetic Testing For Unaffected 19- To 24-Year-Old Patients., Madison C. Groene, Terri Blase Ms, Cgc, Jessica Maxwell Md, Frcsc
Genetic Counseling Capstones
Prior literature has described unique psychosocial considerations for emerging adults (18- to 25-year-olds) considering predictive BRCA genetic testing. Due to these unique concerns, the Society of Gynecologic Oncology (SGO) recommends waiting until individuals are older than 21 before offering testing. While primary care providers (PCPs) are important stakeholders in increasing access to hereditary cancer genetic testing, their approach for emerging adults has not been previously described. We surveyed PCPs in Nebraska regarding their pre- and post-test clinical practices as well as attitudes towards BRCA genetic testing for unaffected 19- to 24-year-olds. Pre-test clinical practice questions and attitudes questions were asked …
Meditation-Type Exercise For The Management Of Chemotherapy Related Cognitive Impairment In Breast Cancer Patients, Christine Cain
Meditation-Type Exercise For The Management Of Chemotherapy Related Cognitive Impairment In Breast Cancer Patients, Christine Cain
Evidence-Based Practice Project Reports
Chemotherapy-related cognitive impairment (CRCI), or “chemobrain”, is one of the most troublesome side effects of chemotherapy (Dijkshoorn et al., 2020). Ongoing CRCI may negatively affect relationships, confidence, sleep, fatigue, anxiety, and the ability to return to work activities leading to a decreased quality of life (Johns et al., 2016; Gokal et al., 2018). The purpose of this evidence-based practice (EBP) project was to assess the efficiency of a meditation-type exercise intervention, chair yoga, on decreasing perceived cognitive impairment (PCI) in breast cancer patients. The PICOT question for this project was: In breast cancer patients with chemotherapy related cognitive impairment (P), …
Improving Dose-Response Correlations For Locally Advanced Nsclc Patients Treated With Imrt Or Pspt, Yulun He
Improving Dose-Response Correlations For Locally Advanced Nsclc Patients Treated With Imrt Or Pspt, Yulun He
Dissertations & Theses (Open Access)
The standard of care for locally advanced non-small cell lung cancer (NSCLC) is concurrent chemo-radiotherapy. Despite recent advancements in radiation delivery methods, the median survival time of NSCLC patients remains below 28 months. Higher tumor dose has been found to increase survival but also a higher rate of radiation pneumonitis (RP) that affects breathing capability. In fear of such toxicity, less-aggressive treatment plans are often clinically preferred, leading to metastasis and recurrence. Therefore, accurate RP prediction is crucial to ensure tumor coverage to improve treatment outcome. Current models have associated RP with increased dose but with limited accuracy as they …

Automating The Radiation Therapy Treatment Planning Process For Pediatric Patients With Medulloblastoma, Soleil Hernandez
Dissertations & Theses (Open Access)
Over the past 50 years, pediatric cancer 5-year survival rates increased from 20% to 80% in high-income countries, however, these trends have not been mirrored in low-and-middle-income countries (LMICs). This is due in part to delayed diagnosis, higher rates of advanced disease at presentation and a growing lack of access to high quality medical personnel and technology necessary to deliver complex treatments.
The long-term goal of this study was to alleviate demanding workflows and increase global access to high-quality pediatric radiation therapy by harnessing the power of artificial intelligence to automate the radiation therapy treatment planning process for pediatric patients …

Role Of Mitochondrial Outer Membrane Translocase Subunit, Tomm22, In Pancreatic Cancer Pathobiology, Mary Oluwadamilola Haastrup
Role Of Mitochondrial Outer Membrane Translocase Subunit, Tomm22, In Pancreatic Cancer Pathobiology, Mary Oluwadamilola Haastrup
<strong> Theses and Dissertations </strong>
Pancreatic cancer (PC) is a highly deadly malignancy with no effective biomarkers for early diagnosis, accurate monitoring and/or surveillance. Due to the late staged diagnosis in the majority of the cases, therapeutic interventions are limited resulting in high mortality. Recent studies continue to discover the diverse roles of mitochondria in pancreatic tumorigenesis, potentiating mitochondria as attractive targets for therapeutics and biomarker development. Although mitochondria have their own genome, most mitochondrial proteins (∼99%) are nuclear-encoded and imported into mitochondria by a specialized protein import system consisting of seven machineries. Among these machineries, translocase of the outer mitochondrial membrane (TOMM) machinery, comprising …
Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison L. Stevens
Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison L. Stevens
Honors Theses
Head and neck squamous cell carcinoma (HNSCC) accounts for around 4% of all cancers in the USA. HNSCC includes cancers of the oral cavity, oropharynx, nasopharynx, hypopharynx, and larynx. Reprogramming of mitochondrial metabolism has been known to promote oncogenesis. NDUFAB1, a nuclear encoded subunit of respiratory complex I (RCI) in the inner mitochondrial membrane, is abundantly expressed at the mRNA level in HNSCC patients. Based on this finding, we hypothesize that NDUFAB1 protein expression is high in HNSCC and that NDUFAB1 expression predicts a poor prognosis in HNSCC patients. We determined NDUFAB1 expression in HNSCC using immunohistochemistry and pathology guided …
Apoptosis Induction In Jurkat T-Lymphocytes By Proton Pump Inhibitors (Ppis), Shreya Murali, Randall Reif
Apoptosis Induction In Jurkat T-Lymphocytes By Proton Pump Inhibitors (Ppis), Shreya Murali, Randall Reif
Student Research Submissions
Apoptosis, commonly known as programmed cell death, constantly occurs in humans. As a cancer cell increases in acidity, apoptosis is induced. In healthy cells, proton pump proteins allow for H+ ions to permeate cellular membranes, regulating pH. However, proton pump inhibitors (PPIs), such as omeprazole, prevent proton movement. In previous studies, omeprazole induced cell death in Jurkat T lymphocytes; however, there was no confirmation of whether the cells died through apoptosis, or through necrosis, where the cell bursts. By using Annexin-V staining, the effects of omeprazole, dexlansoprazole, and esomeprazole on apoptosis induction can be measured. Cell death was observed …
Increasing Colorectal Cancer Screening Uptake Among Hispanic/Latino Patients: A Quality Improvement Initiative, Erick Hernandez Campos, Elizabeth Morse, David Phillippi
Increasing Colorectal Cancer Screening Uptake Among Hispanic/Latino Patients: A Quality Improvement Initiative, Erick Hernandez Campos, Elizabeth Morse, David Phillippi
DNP Scholarly Projects
Background: In 2021, cancer (CRC) screening rates for Latino men (42%) and women (47.5%) remain well below the Health People 2020 target (70.5%). Extensive documentation of barriers for screening include language, insurance status, and other sociocultural barriers which contribute to delays in diagnosis and/or diagnosis at advanced stages of the disease, and worse health outcomes. Latinos need culturally and linguistically appropriate health promotion interventions aimed to increase CRC screening rates with any modality (FIT, Cologuard, or Colonoscopy).
Methods: The Donabedian Structure-Process-Outcome (S-P-O) Model for quality improvement was used to develop and target a provider-driven, language-concordant communication interventions for …
