Markov Decision Process Approach To Strategize National Breast Cancer Screening Policy In Data-Limited Settings, Vijeta Deshpande Oct 2019

Markov Decision Process Approach To Strategize National Breast Cancer Screening Policy In Data-Limited Settings, Vijeta Deshpande

Masters Theses

Early diagnosis is a promising strategy to reduce premature mortalities and for optimal use of resources. But the absence of mathematical models specific to the data settings in LMIC’s impedes the construction of economic analysis necessary for decision-makers in the development of cancer control programs. This thesis presents a new methodology for parameterizing the natural history model of breast cancer based on data availabilities in low and middle income countries, and formulation of a control optimization problem to find the optimal screening schedule for mammography screening, solved using dynamic programming. As harms and benefits are known to increase with the …


Antipsychotic Drug Use And Postmenopausal Breast Cancer Risk In The Women’S Health Initiative (Whi): A Prospective Cohort Study, Anna George Jul 2019

Antipsychotic Drug Use And Postmenopausal Breast Cancer Risk In The Women’S Health Initiative (Whi): A Prospective Cohort Study, Anna George

Masters Theses

Breast cancer is the most prevalent form of cancer and the second leading cause of mortality, affecting 1 in 9 women in the United States. Recent studies have shown that antipsychotic drug use is associated with increased prolactin levels, which, in turn, is associated with increased risk of breast cancer. However, studies of the association between antipsychotic drug use and the risk of breast cancer are sparse and have largely been conducted in homogenous populations. Therefore, we evaluated this relationship in postmenopausal women (N = 119 524) in a diverse population of the Women’s Health Initiative (WHI) cohort. Antipsychotic drug …


Obesity-Induced Inflammation In Human Mammary Tissue: A Potential Microenvironment Favorable To The Development Of Postmenopausal Breast Cancer Via The Wnt Signaling Pathway, Agathe A. Roubert Nov 2015

Obesity-Induced Inflammation In Human Mammary Tissue: A Potential Microenvironment Favorable To The Development Of Postmenopausal Breast Cancer Via The Wnt Signaling Pathway, Agathe A. Roubert

Masters Theses

In the United States, over one third of adult women are obese, and one in eight women will be diagnosed with breast cancer in their lifetime. Obesity has been shown to be a risk factor for postmenopausal breast cancer and is associated with increased aggressiveness and poor prognosis regardless of menopausal status. However, the mechanisms involved in the relationship between obesity and breast cancer are still not fully understood. Wnt signaling is often elevated in breast tumors (~60%) and is suspected to play a key role in cancer development. It has been shown that inflammatory cytokines, such as TNF-α, IL-1β, …
