Modeling Of Cns Cancer With A Focus On The Immune Component, Daniel Zamler

Dissertations & Theses (Open Access)

The knowledge surrounding cancers of the central nervous system remains poorly developed, in particular with regard to the immune component. The works contained in this thesis look at craniopharyngioma, glioblastoma, and several forms of brain metastasis. While some attention is given to the tumor cells themselves, as well as the patient setting which these studies model, the immune component of disease progression and treatment plays a strong role in each and is the primary focus of the works contained.

Craniopharyngioma is a relatively rare tumor in adults. Although histologically benign, it can be locally aggressive and may require additional therapeutic …

Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson

Theses & Dissertations

Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …

Cancer Stem Cells In The Screening Of Anticancer Drugs For Central Nervous System Tumors, Sarah Elizabeth Daron-Mathis

Theses, Dissertations and Capstones

There is a growing need (in the medical field) to design personalized therapy for cancer patients. Decades of cancer research have found no silver bullet that can cure all or even most patients. This study evaluated four patients affected by central nervous system (CNS) tumors (Ependymoma and Glioblastoma), and found that tumors with the same histology had unique responses to treatment. Each sample presented different levels of heterogeneity in expressed biomarkers and responded to drugs at varying levels.

Oncologists conventionally treat cancer patients with drugs tested in large clinical trials. However, often patients do not experience positive outcomes following treatments …
