Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad Feb 2024

Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad

Dissertations, Theses, and Capstone Projects

The overexpression of HER2 accounts for 20-30% of breast cancer tumors and not only serves as a marker for poor predictive clinical outcomes but also as a target for treatment. Antibody-drug conjugates (ADCs) combine the selectivity of monoclonal antibodies (mAbs) with the efficacy of chemotherapeutic drugs to provide targeted treatment without toxicity to normal tissue. Most of the ADCs currently in the clinic for cancer chemotherapy are based on complex organic molecules. In contrast, the conjugation of metallodrugs to mAbs has been overlooked when there is enormous potential in this area with the resurgence of metal-based drugs as prospective cancer …

Improving Screening Mammography Recommendation And Referral In Primary Care Through Implementation Of A Provider Prompt, Christon Elfring Dec 2023

Improving Screening Mammography Recommendation And Referral In Primary Care Through Implementation Of A Provider Prompt, Christon Elfring

Doctoral Projects

In the United States, breast cancer has been established as the second most prevalent cancer among women (Centers for Disease Control [CDC], 2022a). There may be no symptoms present in the early stages of breast cancer and a low potential to spread during the early phases (World Health Organization [WHO], 2021). Mammography is the only test that has been shown to reduce deaths from breast cancer as it allows for early detection when cancer is in its most treatable stage improving survival and lessening the need for extensive treatment (American College of Radiology [ACR], n.d.). While the effectiveness of screening …

A Quantitative Visualization Tool For The Assessment Of Mammographic Risky Dense Tissue Types, Margaret R. Mccarthy Aug 2023

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 …

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 …

Hybrid Power Spectral And Wavelet Image Roughness Analysis, Basel White May 2023

Hybrid Power Spectral And Wavelet Image Roughness Analysis, Basel White

Electronic Theses and Dissertations

The Two-Dimensional Wavelet Transform Modulus Maxima (2D WTMM) sliding window methodology has proven to be a robust approach, in particular for the extraction of the Hurst (H) roughness exponent from grayscale mammograms. The power spectrum is a computational analysis based on the Fourier transform that can be used to estimate the roughness of a scale-invariant image or region via the calculation of H. We aim to examine how the calculation of H in fractional Brownian motion (fBm) images and mammograms can be improved. fBm images are generated for H ∈ [0.00,1.00] for testing through the previous 2D …

Dissertations & Theses (Open Access)

Breast cancer-related lymphedema (BCRL) manifests as swelling of the upper extremities and trunk as a result of lymphatic fluid buildup due to radiation therapy (RT), surgical lymph node removal, or chemotherapy. As there is currently no cure, BCRL treatment aims to improve quality of life (QOL). First-line treatment involves specialized massage therapy and the use of compression garments. Second-line treatments include reparative lymphatic microsurgeries such as lymphovenous bypass (LVB) and/or vascularized lymph node transplant (VLNT). There is a need for better understanding of the etiology of BCRL and lymphatic microsurgery outcomes. Blood specimens and near-infrared fluorescent lymphatic imaging (NIRF- LI)data …


Investigating Cellular Imaging Techniques For Cancer Cell Tracking, Natasha Knier Apr 2023

Investigating Cellular Imaging Techniques For Cancer Cell Tracking, Natasha Knier

Electronic Thesis and Dissertation Repository

Introduction: Breast cancer remains a leading cause of mortality among women due to the propensity of breast tumours to spread and metastasize to distant sites, including the brain. Early detection of metastatic disease has been challenging, and typical methods of treatment often fail. A significant roadblock in advancing the detection and treatment of breast cancer brain metastases is the lack of representative experimental preclinical models and methods of studying its progression in vivo. Methods: First, we use iron-based cellular MRI to noninvasively track the progression of a brain metastatic breast cancer cell line in murine models with varying immune …

The Influence Of Administrative Timing In Triple-Negative Breast Cancer Treatments, Emily Mailloux Jan 2023

The Influence Of Administrative Timing In Triple-Negative Breast Cancer Treatments, Emily Mailloux

Electronic Theses and Dissertations

Breast cancer accounts for 25% of all cancers in Canadian women, and 15-20% of these are triple-negative breast cancers (TNBC), which have a poorer prognosis than other breast cancer subtypes. TNBC lacks expression of the estrogen receptor, progesterone receptor, and the human epidermal growth factor receptor 2 (HER2), which are common therapeutic targets in breast cancer. Due to the lack of target therapy, generalized chemotherapy treatments are used instead. The standard of care for treatment of TNBC instead consists of doxorubicin (A), cyclophosphamide (C) paclitaxel (T), and carboplatin (Carbo), that target various aspects of the cell cycle to induce cell …


Bayesian Methods For Graphical Models With Neighborhood Selection., Sagnik Bhadury Dec 2022

Bayesian Methods For Graphical Models With Neighborhood Selection., Sagnik Bhadury

Electronic Theses and Dissertations

Graphical models determine associations between variables through the notion of conditional independence. Gaussian graphical models are a widely used class of such models, where the relationships are formalized by non-null entries of the precision matrix. However, in high-dimensional cases, covariance estimates are typically unstable. Moreover, it is natural to expect only a few significant associations to be present in many realistic applications. This necessitates the injection of sparsity techniques into the estimation method. Classical frequentist methods, like GLASSO, use penalization techniques for this purpose. Fully Bayesian methods, on the contrary, are slow because they require iteratively sampling over a quadratic …

Effect Of Body Mass Index, Testosterone, And Insulin On Breast Cancer: A Mendelian Randomization Study And Investigation Of Selection Bias, Kezhen Fei

Dissertations and Theses

BACKGROUND: Female breast cancer is the most studied cancer, and the second leading cause of cancer death in women, whose aetiology is still not completely clear. The parallel increase of incident obesity and breast cancer in women worldwide raises the question of the role of adiposity, measured by body mass index (BMI), and of major anabolic hormones, such as insulin and testosterone, on breast cancer. Observational studies are open to confounding making it difficult to clearly demonstrate causal effects. Several mendelian randomization (MR) studies have shown inverse association of BMI with breast cancer. To assess selection bias in MR …

Increasing Genetic Testing Rates To Improve Early Detection And Prevention Of Breast And Ovarian Cancer In Women, Makensey Beth Durrant

UNLV Theses, Dissertations, Professional Papers, and Capstones

Screening rates for cancer related genetic mutations are low in the primary care setting, despite evidence-based guidelines recommending screening in all patients who meet criteria. Genetic mutations, such as the breast cancer susceptibility 1 and 2 (BRCA1/2) gene mutations, drastically increase breast and ovarian cancer risk in patients. The United States Preventive Services Task Force (USPSTF) and the National Comprehensive Cancer Network (NCCN) provide evidence-based guidelines on criteria for genetic testing in women at risk for breast and ovarian cancer related gene mutations. Primary care providers (PCPs), including advanced practice registered nurses (APRNs), are at the front lines of preventative …


Assessing Identification Of Newly Diagnosed Breast Cancer Patients For Referral To Genetic Counseling, Corinne Marie Locke Apr 2022

Assessing Identification Of Newly Diagnosed Breast Cancer Patients For Referral To Genetic Counseling, Corinne Marie Locke

Theses and Dissertations

Since 1998, the National Comprehensive Cancer Network (NCCN) guidelines have specified clinical indications for genetic testing for breast cancer susceptibility genes, but retrospective studies have shown that, despite meeting the NCCN criteria, patients are not always advised of the option of genetic testing. Further compounding this issue, studies have shown that cancer family history intake and documented family history can be incomplete even when taken by oncology providers.
