Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Theses and Dissertations
Background: Breast cancer (BC) survivors are at high risk for heart failure due to curative cancer therapies. In non-cancer populations, physical activity is a first line treatment for preventing cardiovascular disease. This study examined whether more physical activity was associated with better submaximal exercise capacity and cardiac function during the first three months of cancer therapy.
Methods: Participants included 223 women with stage I-III BC before therapy and after three months of undergoing treatment and 126 controls. Leisure time physical activity was reported using the Godin Sheppard leisure time exercise questionnaire. Cardiac function was assessed by cardiac magnetic resonance, and …
Multi-Modality Automatic Lung Tumor Segmentation Method Using Deep Learning And Radiomics, Siqiu Wang
Multi-Modality Automatic Lung Tumor Segmentation Method Using Deep Learning And Radiomics, Siqiu Wang
Theses and Dissertations
Delineation of the tumor volume is the initial and fundamental step in the radiotherapy planning process. The current clinical practice of manual delineation is time-consuming and suffers from observer variability. This work seeks to develop an effective automatic framework to produce clinically usable lung tumor segmentations. First, to facilitate the development and validation of our methodology, an expansive database of planning CTs, diagnostic PETs, and manual tumor segmentations was curated, and an image registration and preprocessing pipeline was established. Then a deep learning neural network was constructed and optimized to utilize dual-modality PET and CT images for lung tumor segmentation. …
Exosomal Mirnas As Biomarkers For Radiation Toxicity In Breast Cancer Patients, Mina V. Mcginn
Exosomal Mirnas As Biomarkers For Radiation Toxicity In Breast Cancer Patients, Mina V. Mcginn
Theses and Dissertations
Radiotherapy (RT) is a standard treatment for most breast cancer patients (BCPs), but is often accompanied by acute and late toxic effects in normal tissue. Exosomes are nano vesicles about 30-150nm in size that originate from the endosomal network and are found in most body fluids. Exosomes are a fundamental driver of intercellular communication by transferring proteins, lipids and microRNA (miRNA). Exosomal miRNA (Exo-miRNA) signatures may serve as non-invasive prediction biomarkers of post-radiation toxicities of BCPs. Eighty six BCPs treated in the Radiation Oncology Department were enrolled in an IRB approved study. BCPs were evaluated weekly during RT and at …

Breast cancer has the highest incidence rate of all cancers globally in women, and those of African descent, especially West African females, face higher rates of triple-negative breast cancer (TNBC), a more aggressive form of breast cancer. Immunotherapy for breast cancer is a relatively new treatment option, and research is ongoing to identify the best combination treatments for increasing survival of those diagnosed with TNBC. Eganelisib (IPI-549: a PI3K-gamma inhibitor that works to shift M2 macrophages to M1 to augment T cell function) with other combinatory treatments has shown promising results in reducing tumor growth and increasing survival in mice. …

Tumors may induce tolerogenesis through signaling dendritic cells to produce tolerogenic molecules, such as indoleamine 2, 3-dioxygenase 1 (IDO1). Tumor-associated immunosuppression is associated with higher mortality in patients. Small interfering RNA (siRNA) has been shown to silence specific target genes in the target cell. The siRNA associated with these genes could support a gene knockdown of these immunosuppressors and reduce mortality. Delivery of these therapeutic nucleic acids is difficult in vivo because siRNA is easily broken down inside the cell and the bloodstream through present nucleases. Use of liposome polymers has been reviewed extensively in literature. YSK12-C4, a lipid nanoparticle …

Targeting Bcl-2 Family Proteins In Therapy Induced Senescent Cancer Cell Models, Wade Cook
Theses and Dissertations
Non-small Cell Lung Cancer (NSCLC) originates from numerous different cell types in the lungs and is among the deadliest of cancers. Head and Neck Squamous Cell Carcinomas (HNSCC) are derived from the mucosal membranes of the oral cavity, pharynx, and larynx. Both NSCLC and HNSCC are predominately caused by tobacco smoke inhalation and as such mutations in the tumor suppressor gene TP53 are common. Since similarities exist in the root cause of NSCLC and HNSCC, they may also share similarities in treatment methods. Cisplatin is a platinum-based DNA damaging agent that has been used as a cancer chemotherapy for decades. …
