Cancer is a major public health problem worldwide. Colon cancer ranks as the third most common causes of cancer mortality in the United States, with an estimated 96,830 new cases and 50,310 deaths in 2014. Colon cancer develops in the digestive tract where benign growths called polyps transform into malignant tumors. Colon cancer cells invade and destroy nearby tissue and can …

Subsequent Primary Malignancies In Survivors Of Childhood Cancer, Emily Matson, Dr. Ray Merrill

Journal of Undergraduate Research

Although cancer is often considered a disease of old age, it kills more children ages 1 to 14 years in the United States than any other cause, except unintentional injuries [1]. Through advances in diagnosing and treating cancer, child survival of cancer has improved in recent years [1, 2]. However, more research is needed on the risk of subsequent cancer following an initial diagnosis of cancer, of the same or another anatomical site. Associations between childhood and secondary cancers have implications for patient follow-up, by providing health professionals with better information on which subsequent cancer sites are most likely to …

Long-Term Financial Burden Of Breast Cancer: Experiences Of A Diverse Cohort Of Survivors Identified Through Population-Based Registries, Reshma Jagsi, John A.E. Pottow, Kent A. Griffith, Cathy Bradley, Ann S. Hamilton, John Graff Rutgers University, Steven J. Katz, Sarah T. Hawley

Articles

Purpose: To evaluate the financial experiences of a racially and ethnically diverse cohort of long-term breast cancer survivors (17% African American, 40% Latina) identified through population-based registries. Methods: Longitudinal study of women diagnosed with nonmetastatic breast cancer in 2005 to 2007 and reported to the SEER registries of metropolitan Los Angeles and Detroit. We surveyed 3,133 women approximately 9 months after diagnosis and 4 years later. Multivariable models evaluated correlates of self-reported decline in financial status attributed to breast cancer and of experiencing at least one type of privation (economically motivated treatment nonadherence and broader hardships related to medical expenses). …

Recent Advances In The Molecular Characterization Of Circulating Tumor Cells, Lori E. Lowes, Alison L. Allan

Anatomy and Cell Biology Publications

Although circulating tumor cells (CTCs) were first observed over a century ago, lack of sensitive methodology precluded detailed study of these cells until recently. However, technological advances have now facilitated the identification, enumeration, and characterization of CTCs using a variety of methods. The majority of evidence supporting the use of CTCs in clinical decision-making has been related to enumeration using the CellSearch((R)) system and correlation with prognosis. Growing evidence also suggests that CTC monitoring can provide an early indication of patient treatment response based on comparison of CTC levels before and after therapy. However, perhaps the greatest potential that CTCs …

A Phylogenetic Model For Understanding The Effect Of Gene Duplication On Cancer Progression, Qin Ma, Jaxk H. Reeves, David A. Liberles, Lili Yu, Zheng Chang, Jing Zhao, Juan Cui, Ying Xu, Liang Liu

Biostatistics: Faculty Publications

As biotechnology advances rapidly, a tremendous amount of cancer genetic data has become available, providing an unprecedented opportunity for understanding the genetic mechanisms of cancer. To understand the effects of duplications and deletions on cancer progression, two genomes (normal and tumor) were sequenced from each of five stomach cancer patients in different stages (I, II, III and IV). We developed a phylogenetic model for analyzing stomach cancer data. The model assumes that duplication and deletion occur in accordance with a continuous time Markov Chain along the branches of a phylogenetic tree attached with five extended branches leading to the tumor …

Repair Of Oxidative Dna Damage And Cancer: Recent Progress In Dna Base Excision Repair, Timothy L. Scott, Suganya Rangaswamy, Christina A. Wicker, Tadahide Izumi

Toxicology and Cancer Biology Faculty Publications

SIGNIFICANCE: Reactive oxygen species (ROS) are generated by exogenous and environmental genotoxins, but also arise from mitochondria as byproducts of respiration in the body. ROS generate DNA damage of which pathological consequence, including cancer is well established. Research efforts are intense to understand the mechanism of DNA base excision repair, the primary mechanism to protect cells from genotoxicity caused by ROS.

RECENT ADVANCES: In addition to the notion that oxidative DNA damage causes transformation of cells, recent studies have revealed how the mitochondrial deficiencies and ROS generation alter cell growth during the cancer transformation.

Prevalence Corrected Prostate Cancer Incidence Rates And Trends, Mark K. Morris, Dr. Ray Merrill

Journal of Undergraduate Research

Conventional cancer incidence rates reported in the United States represent the number of newly diagnosed cases in a given year divided by the mid-year population for that year (1). Incidence rates have been reported on an annual basis in the United States since 1973, when the National Cancer Institute initiated the Surveillance, Epidemiology, and End Results (SEER) Program (2). Population-based site-specific cancer incidence rates are commonly thought of as measures reflecting the average risk of developing the disease (3). However, this assumes that the rate calculation includes new cases of the cancer in the numerator and the at-risk population for …

Paracrine Apoptotic Effect Of P53 Mediated By Tumor Suppressor Par-4, Ravshan Burikhanov, Tripti Shrestha-Bhattarai, Nikhil Hebbar, Shirley Qiu, Yanming Zhao, Gerard P. Zambetti, Vivek M. Rangnekar

Radiation Medicine Faculty Publications

The guardian of the genome, p53, is often mutated in cancer and may contribute to therapeutic resistance. Given that p53 is intact and functional in normal tissues, we harnessed its potential to inhibit the growth of p53-deficient cancer cells. Specific activation of p53 in normal fibroblasts selectively induced apoptosis in p53-deficient cancer cells. This paracrine effect was mediated by p53-dependent secretion of the tumor suppressor Par-4. Accordingly, the activation of p53 in normal mice, but not p53⁻/⁻ or Par-4⁻/⁻ mice, caused systemic elevation of Par-4, which induced apoptosis of p53-deficient tumor cells. Mechanistically, p53 …

Patient Navigator's Role Definition, Joann Smith

Nursing Theses and Capstone Projects

Patient navigation as a care coordination model continues to evolve. Early programs focused on access to care for the underserved and uninsured. With no standard credentials, title, training or job descriptions, navigator programs are as varied as the people who perform these duties. The nurse navigator provides a holistic approach to care delivery and focuses on care coordination, education, and physical, social and emotional aspects of care. Workload for the navigators is increasing as a result of patient, facility, departmental, and national accreditation demands. The goal of this capstone project was to redefine the job descriptions of the Oncology Nurse …

Identification And Characterization Of Downstream Effector Protein(S) Regulated By P53 And Prb, Miranda B. Carper

Theses, Dissertations and Capstones

A commonality among cancer types is the high frequency of mutations that inhibit or alter signaling of the p53 and pRb (Retinoblastoma) tumor suppressors. These genes regulate processes vital for cancer suppression such as apoptosis, senescence, and cell cycle arrest among others. Loss of both p53 and pRb promotes processes that support cancer progression and is associated with decreased patient survival and increased rates of tumor reoccurrence. Although data points to the ability of p53 and pRb to collaborate and to inhibit tumorigenesis, it remains unclear how p53 and pRb cooperate toward this task. Using RNA expression profiling, 179 p53 …

Lost In Translation: Animal Models And Clinical Trials In Cancer Treatment, Isabella W.Y. Mak, Nathan Evaniew, Michelle Ghert

Human Clinical Trials Collection

Due to practical and ethical concerns associated with human experimentation, animal models have been essential in cancer research. However, the average rate of successful translation from animal models to clinical cancer trials is less than 8%. Animal models are limited in their ability to mimic the extremely complex process of human carcinogenesis, physiology and progression. Therefore the safety and efficacy identified in animal studies is generally not translated to human trials. Animal models can serve as an important source of in vivo information, but alternative translational approaches have emerged that may eventually replace the link between in vitro studies and …

Spontaneous/Radical Remission Of Cancer: Transpersonal Results From A Grounded Theory Study, Kelly A. Turner

International Journal of Transpersonal Studies

This grounded theory study aimed to collect hypotheses for spontaneous or radical remission (RR) of cancer, which is a remission that occurs without medical treatment, or with medical treatment considered inadequate to produce the remission. Interviews were conducted with 20 RR survivors and 50 non-conventional healers from 11 countries. Results showed that three underlying beliefs emerged: 1. Cancer thrives under certain conditions; 2. Illness represents blockage; and 3. A body-mind-spirit interaction exists. Six factors believed to be possible causes of RR also emerged: 1. Diet change; 2. Deepening spirituality; 3. Increasing happiness; 4. Releasing suppressed emotions; 5. Taking supplements; and …

Parp Inhibition: A Method Of Treating And Preventing Certain Cancers, Chana Tropper

The Science Journal of the Lander College of Arts and Sciences

Breast cancer is one of the largest causes of cancer related deaths in women. Less than 5% of breast cancer cases are genetically inherited and most often develop after menopause. The BRCA gene mutation is a genetic inheritance which increases ones chances of developing breast cancer at a young age tenfold. Recent research has proposed a method of treatment in genetically inherited breast cancers by taking advantage of the impaired DNA repair pathway caused by the BRCA mutation. The combination of a BRCA mutation, which leads to deficient double strand DNA repair, and PARP inhibition, which leads to deficient single …

Absence Of Manganese Superoxide Dismutase Delays P53-Induced Tumor Formation., Adam J. Case, Frederick E. Domann

Journal Articles: Cellular & Integrative Physiology

BACKGROUND: Manganese superoxide dismutase (MnSOD) is a mitochondrial antioxidant enzyme that is down-regulated in a majority of cancers. Due to this observation, as well as MnSOD's potent antioxidant enzymatic activity, MnSOD has been suggested as a tumor suppressor for over 30 years. However, testing this postulate has proven difficult due to the early post-natal lethality of the MnSOD constitutive knock-out mouse. We have previously used a conditional tissue-specific MnSOD knock-out mouse to study the effects of MnSOD loss on the development of various cell types, but long-term cancer development studies have not been performed. We hypothesized the complete loss of …

Cancer Trends And Risk Factors In Cyprus, Evi A. Farazi

Journal Articles: Epidemiology

Cyprus, a European Union member state, is a small island in the Mediterranean with a population approaching 900,000 people. Cancer is the second leading cause of death; more therapeutic options for any patient with the disease are available in a central oncology centre in the capital of the island (Nicosia) and fewer therapeutic options (e.g. chemotherapy and hormone therapy only) in a few other public hospitals. Palliative care is offered in several hospices and hospitals, although the field needs improvement. With regards to screening, a national breast cancer screening programme has been in place countrywide since 2007 and is offered …

Pharmacy Faculty Articles and Research

Several novel N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamides derivatives were prepared as potential antiproliferative agents. The in vitro antiproliferative activity of the synthesized compounds was investigated against a panel of tumor cell lines including breast cancer cell lines (MDA-MB-231, T-47D) and neuroblastoma cell line (SK-N-MC) using MTT colorimetric assay. Etoposide, a well-known anticancer drug, was used as a positive standard drug. Among synthesized compounds, 4-methoxy-N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamide (5i) showed the highest antiproliferative activity against MDA-MB-231, T-47D, and SK-N-MC cells. Furthermore, pentafluoro derivatives 5a and 6a exhibited higher antiproliferative activity than doxorubicin against human leukemia cell line (CCRF-CEM) and breast adenocarcinoma (MDAMB- 468) cells. Structure-activity relationship studies revealed …

Role Of Physical Exercise In Reducing Depression And Improving Mental Health In Cancer Survivors, Gregory Levin

Theses: Doctorates and Masters

Cancer survivors are more than twice as likely as the general population to suffer the debilitating effects of depression. This comorbid condition is associated with several negative consequences, such as reduction in compliance with cancer treatments, and hastened mortality. Recent research has examined the therapeutic effect of exercise on depression and reported excellent results of similar magnitude to those achieved with pharmacotherapy or psychological intervention. However, no research, to date, has examined the effectiveness of exercise on reducing depression in depressed cancer survivors. In order to address this important question this thesis reviewed previous literature in the area of cancer …

Altered Mucins (Muc) Trafficking In Benign And Malignant Conditions., Suhasini Joshi, Sushil Kumar, Amit Choudhury, Moorthy P. Ponnusamy, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Mucins are high molecular weight O-glycoproteins that are predominantly expressed at the apical surface of epithelial cells and have wide range of functions. The functional diversity is attributed to their structure that comprises of a peptide chain with unique domains and multiple carbohydrate moieties added during posttranslational modifications. Tumor cells aberrantly overexpress mucins, and thereby promote proliferation, differentiation, motility, invasion and metastasis. Along with their aberrant expression, accumulating evidence suggest the critical role of altered subcellular localization of mucins under pathological conditions due to altered endocytic processes. The mislocalization of mucins and their interactions result in change in the density …

Initiation And Completion Of Adjuvant Chemotherapy Among Colorectal Cancer Patients, Ashar Ata

Legacy Theses & Dissertations (2009 - 2024)

Introduction: For regionally advanced colorectal cancers resection followed by adjuvant chemotherapy (ACT) is the recommended treatment. Despite consensus on benefits, studies have shown that a significant proportion of patients do not initiate it. Among those who initiate the survival benefits of chemotherapy cannot be fully realized without completed treatment. Without supplementing treatment information from insurance claims cancer registries are inadequate for assessment of ACT utilization. This study was aimed at measuring the initiation and completion of ACT among colorectal cancer patients and identifying the associated factors.
