Protocol For Care After Lymphoma (Caly) Trial: A Phase Ii Pilot Randomised Controlled Trial Of A Lymphoma Nurse-Led Model Of Survivorship Care, Karen Taylor, David Joske, Max Bulsara, Caroline Bulsara, Leanne Monterosso

Research outputs 2014 to 2021

Introduction:

Lymphoma is the sixth most common cancer diagnosed in Australia and internationally. Owing to the aggressive nature of the disease and intensity of treatment, survivors face long-term effects that impact on quality of life. Current models of follow-up post-treatment fail to address these complex issues. Given that 74% of patients with lymphoma cancer now survive 5 years beyond diagnosis and treatment, it is important to address this gap in care.

Aim:

To determine self-reported informational and practical needs, anxiety, depression, stress, coping and empowerment at baseline, 3 and 6 months.

Methods and analysis:

A pilot randomised controlled trial will …


Autoantibody Production In Cancer—The Humoral Immune Response Toward Autologous Antigens In Cancer Patients, Pauline Zaenker, Elin Solomonovna Gray, Melanie Ruth Ziman Jan 2016

Autoantibody Production In Cancer—The Humoral Immune Response Toward Autologous Antigens In Cancer Patients, Pauline Zaenker, Elin Solomonovna Gray, Melanie Ruth Ziman

Research outputs 2014 to 2021

A link between autoimmune responses and cancer via autoantibodies was first described in the 1950s. Since, autoantibodies have been studied for their potential use as cancer biomarkers, however the exact causes of their production remain to be elucidated. This review summarizes current theories of the causes of autoantibody production in cancer, namely:

1) defects in tolerance and inflammation,

2) changes in protein expression levels,

3) altered protein structure, and

4) cellular death mechanisms.

We also highlight the need for further research into this field to improve our understanding of autoantibodies as biomarkers for cancer development and progression.


The Role Of Trauma In Disparities For Cancer-Related Health: A Call To Action, Megan Bair-Merritt Dec 2015

The Role Of Trauma In Disparities For Cancer-Related Health: A Call To Action, Megan Bair-Merritt

Journal of Health Disparities Research and Practice

Cancer is the second leading cause of death in the United States. In this brief report, we describe the current literature on interpersonal trauma (i.e., sexual abuse and intimate partner violence) and cancer. Concordant with the general population, between 20% and 50% of cancer patients have experienced interpersonal trauma. Experiences with interpersonal trauma not only appear to increase risk for developing cancer, but may also act as a roadblock to accessing appropriate preventive testing and to receiving adequate support during cancer care. Healthcare providers can play an important role in making cancer-related care more trauma-informed.


Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale Dec 2015

Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale

Theses & Dissertations

Combination chemotherapy is commonly used to treat cancer, because such a therapy regimens usually involve sequential administration of multiple drugs and allow targeting different cell signaling pathway. The co-delivery of drug combination at a controlled ratio via the same vehicle is offering the advantages such as spatial-temporal synchronization of drug exposure, synergistic therapeutic effects and suppression of drug resistance. Undoubtedly, there are several molecular and pharmacological factors that determine the effectiveness of drug combinations. A rationally designed drug combination is required since certain drug ratios and the definitive exposure to the targets of interest can only be synergistic while others …


Epacs: Epigenetic Regulators That Affect Cell Survival In Cancer., Catherine Murari Dec 2015

Epacs: Epigenetic Regulators That Affect Cell Survival In Cancer., Catherine Murari

Theses & Dissertations

Cyclic adenosine monophosphate (cAMP) is a second messenger responsive to many external stimuli, playing an important role in cellular gene expression, metabolism, migration, differentiation, hypertrophy, apoptosis and secretion. All of these cellular functions are important in many diseases including cancer. Most of its effects were initially attributed to the classical protein kinase A (PKA) protein, but cellular functions such as proliferation and migration were found to be PKA independent and dependent on the newly discovered exchange proteins directly activated by cAMP (EPACs). EPACs are single polypeptides that primarily function as guanine exchange factors (GEFs) for Rap proteins that allow the …


The Effects Of Ketorolac And Its Enantiomers On Breast Cancer Proliferation And Metastasis, Amanda Sheree Peretti Dec 2015

The Effects Of Ketorolac And Its Enantiomers On Breast Cancer Proliferation And Metastasis, Amanda Sheree Peretti

Biomedical Sciences ETDs

Breast cancer is the second leading cause of cancer related deaths in women. Advanced breast cancer can metastasize to the lungs, liver, bones and brain becoming fatal conditions for many patients. There is a dire need for metastasis preventing medications, however the process required for a medication to become FDA approved for clinical use is long and arduous. Studies have found promising benefits for breast cancer patients given ToradolTM, or racemic ketorolac, as an NSAID during resection surgery. However, long-term use of racemic ketorolac is not recommended. Currently FDA-approved for use in the racemic form, ketorolac has the potential to …


Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig Dec 2015

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations and Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

Immunomodulation Of Myeloid-Derived Suppressor Cells By Particulate B-Glucan In Cancer., Sabrin Husein Albeituni

Electronic Theses and Dissertations

Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature myeloid cells that promote tumor progression. In this study, we investigated the effect of dectin-1 stimulation by yeast-derived particulate β-glucan in MDSC function and differentiation in cancer. In vivo treatment of mice bearing lewis lung carcinoma and mammary cell carcinoma with particulate β-glucan decreased tumor weight and splenomegaly, and reduced the accumulation of polymorphonuclear-MDSC (PMN-MDSC) but not monocytic-MDSC (M-MDSC) in the spleen and tumor. In addition, particulate β-glucan differentially modulated the function of different MDSC subsets; it enhanced PMN-MDSC respiratory burst and apoptosis, and induced the differentiation of M-MDSC into …

Indian Journal of Research in Homoeopathy

Adverse side effects of chemotherapy during cancer treatment have shifted considerable focus towards therapies that are not only targeted but are also devoid of toxic side effects. We evaluated the antitumorigenic activity of sulphur, and delineated the molecular mechanisms underlying sulphurinduced apoptosis in non-small cell lung carcinoma (NSCLC) cells. A search for the underlying mechanism revealed that the choice between the two cellular processes, NFκBp65-mediated survival and p53-mediated apoptosis, was decided by the competition for a limited pool of transcriptional coactivator protein p300 in NSCLC cells. In contrast, sulphur inhibited otherwise upregulated survival signaling in NSCLC cells by perturbing the …

College of Nursing Faculty Research and Publications

Aims: Cancer-related fatigue (CRF) is often accompanied by depressed mood, both of which reduce functional status and quality of life. Research suggests that increased expression of pro-inflammatory cytokines is associated with skeletal muscle wasting and depressive- and fatigue-like behaviors in rodents and cancer patients. We have previously shown that treatment with ibuprofen, a nonsteroidal anti-inflammatory drug, preserved muscle mass in tumor-bearing mice. Therefore, the purpose of the present study was to determine the behavioral effects of ibuprofen in a mouse model of CRF.

Main methods: Mice were injected with colon-26 adenocarcinoma cells and treated with ibuprofen (10 mg/kg) in the …


Incidence Of Breast, Colorectal And Lung Cancers And Mortality Among Women Within Midwestern States, Ruth M. Perez, Matthew Rappelt, Kathryn Kossow, Maharaj Singh Nov 2015

Incidence Of Breast, Colorectal And Lung Cancers And Mortality Among Women Within Midwestern States, Ruth M. Perez, Matthew Rappelt, Kathryn Kossow, Maharaj Singh

Journal of Patient-Centered Research and Reviews

Background: Breast, colorectal and lung cancers have been shown to be the most common cancers as well as the leading causes of cancer death among women. Previous studies suggest that the Northeast had significantly higher rates in incidence and mortality than the Midwest, South and Western regions. However, new data indicates that the Midwest now harbors the highest mortality rates. In Wisconsin, the sixth largest state in the Midwest, cancer is the leading cause of death. Differences in incidence and mortality of breast, colorectal and lung cancers have been observed between Wisconsin, other Midwestern states and national data, warranting further …

A Vision For Using Online Portals For Surveillance Of Patient-Centered Communication In Cancer Care, Hardeep Singh, Neeraj K. Arora, Kathleen M. Mazor, Richard L. Street Jr

Patient Experience Journal

The Veterans Health Administration (VHA) is charged with providing high-quality health care, not only in terms of technical competence but also with regard to patient-centered care experiences. Patient-centered coordination of care and communication are especially important in cancer care, as deficiencies in these areas have been implicated in many cases of delayed cancer diagnosis and treatment. Additionally, because cancer care facilities are concentrated within the VHA system, geographical and system-level barriers may present prominent obstacles to quality care. Systematic assessment of patient-centered communication (PCC) may help identify both individual veterans who are at risk of suboptimal care and opportunities for …

Dartmouth Scholarship

The prognosis of advanced oral squamous cell carcinoma (OSCC) patients remains dismal, and a better understanding of the underlying mechanisms is critical for identifying effective targets with therapeutic potential to improve the survival of patients with OSCC. This study aims to clarify the clinical and biological significance of metastasis-associated long non-coding RNA, metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in OSCC. We found that MALAT1 is overexpressed in OSCC tissues compared to normal oral mucosa by real-time PCR. MALAT1 served as a new prognostic factor in OSCC patients. When knockdown by small interfering RNA (siRNA) in OSCC cell lines TSCCA and …

Hypercalcemia Of Malignancy: An Update On Pathogenesis And Management, Aibek E. Mirrakhimov

Internal Medicine Faculty Publications

Hypercalcemia of malignancy is a common finding typically found in patients with advanced stage cancers. We aimed to provide an updated review on the etiology, pathogenesis, clinical presentation, and management of malignancy-related hypercalcemia. We searched PubMed/Medline, Scopus, Embase, and Web of Science for original articles, case reports, and case series articles focused on hypercalcemia of malignancy published from 1950 to December 2014. Hypercalcemia of malignancy usually presents with markedly elevated calcium levels and therefore, usually severely symptomatic. Several major mechanisms are responsible for the development of hypercalcemia of malignancy including parathyroid hormone-related peptide-mediated humoral hypercalcemia, osteolytic metastases-related hypercalcemia, 1,25 Vitamin …

The Homeoprotein Dlx3 And Tumor Suppressor P53 Co-Regulate Cell Cycle Progression And Squamous Tumor Growth, Paul W. Bible, E. Palazzo, M. Kellett, C. Cataisson, A. Gormley, V. Pietroni, Et Al.

Computer Science Faculty publications

Epidermal homeostasis depends on the coordinated control of keratinocyte cell cycle. Differentiation and the alteration of this balance can result in neoplastic development. Here we report on a novel DLX3-dependent network that constrains epidermal hyperplasia and squamous tumorigenesis. By integrating genetic and transcriptomic approaches, we demonstrate that DLX3 operates through a p53-regulated network. DLX3 and p53 physically interact on the p21 promoter to enhance p21 expression. Elevating DLX3 in keratinocytes produces a G1-S blockade associated with p53 signature transcriptional profiles. In contrast, DLX3 loss promotes a mitogenic phenotype associated with constitutive activation of ERK. DLX3 expression is lost in human …


The Effect Of Mindfulness Meditation On Emotional Distress In Adult Cancer Patients, Marie A. Benoit Oct 2015

The Effect Of Mindfulness Meditation On Emotional Distress In Adult Cancer Patients, Marie A. Benoit

Evidence-Based Practice Project Reports

Significant advances in cancer treatments have been made over recent decades resulting in state of the art screening and treatment options that have contributed to higher rates of cancer survivorship. However, despite the increase in cancer survivors, a cancer diagnosis continues to be associated with a significant amount of emotional distress and psychological issues that further add to the burden of the disease. The Institute of Medicine (2008), recognizes that a failure to adequately address this problem results in needless suffering and may obstruct quality of care; thereby, leading to a potentially negative impact on the disease course. Among the …

Pharmacy Faculty Articles and Research

Ligand-directed targeting and capturing of cancer cells is a new approach for detecting circulating tumor cells (CTCs). Ligands such as antibodies have been successfully used for capturing cancer cells and an antibody based system (CellSearch®) is currently used clinically to enumerate CTCs. Here we report the use of a peptide moiety in conjunction with a microcantilever array system to selectively detect CTCs resulting from cancer, specifically breast cancer. A sensing microcantilever, functionalized with a breast cancer specific peptide 18-4 (WxEAAYQrFL), showed significant deflection on cancer cell (MCF7 and MDA-MB-231) binding compared to when exposed to noncancerous (MCF10A and HUVEC) cells. …

Dartmouth Scholarship

Background: Ductal carcinoma in situ (DCIS) is a heterogeneous, pre-invasive lesion associated with an increased risk for future invasive ductal carcinoma. However, accurate risk stratification for development of invasive disease and appropriate treatment decisions remain clinical challenges. DNA methylation alterations are early events in the progression of cancer and represent emerging molecular markers that may predict invasive recurrence more accurately than traditional measures of DCIS prognosis.

Results: We measured DNA methylation using the Illumina HumanMethylation450K array of estrogen-receptor positive DCIS (n = 40) and adjacent-normal (n = 15) tissues from subjects in the New Hampshire Mammography Network longitudinal breast imaging …

The large size of the pig and its similarity in anatomy, physiology, metabolism, and genetics to humans make it an ideal platform to develop a genetically defined, large animal model of cancer. To this end, we created a transgenic "oncopig" line encoding Cre recombinase inducible porcine transgenes encoding KRASG12D and TP53R167H, which represent a commonly mutated oncogene and tumor suppressor in human cancers, respectively. Treatment of cells derived from these oncopigs with the adenovirus encoding Cre (AdCre) led to KRASG12D and TP53R167H expression, which rendered the cells transformed in culture and tumorigenic when engrafted into …

Analyzation Of Metabolic Reprogramming In Drug-Resistant Mcf-7 Cells, Derick Han, Ho Leung, Andrew Vo

Student Scholar Symposium Abstracts and Posters

The Warburg effect states that cancer cells mainly receive their energy from anaerobic glycolysis. Thus, mitochondria play a different role in the metabolism of cancer cells as opposed to normal, healthy cells. In chemotherapy, there is always a chance of the cancer regressing. Making drug-resistant cancer cells to analyze their metabolism may change how cancer is treated. This study aimed to create drug-resistant MCF-7 cell lines with doxorubicin in order to determine the metabolic changes that have occurred in the process of becoming resistant to drug treatments.

Clinical Applications Of A Combination Chemotherapy Using 8-Chloro Camp And 8-Chloro Adenosine, Erik Munoz, Andrea Saich, Andrew Cox, Yu-An Peter Chang

Student Scholar Symposium Abstracts and Posters

Dr. Cho-Chung from the NIH first thought to use halogenated cAMP derivatives as competitive inhibitors of cAMP to slow down cancer cell mitosis. While the iodine and bromine substituted versions showed very little therapeutic actions, 8-Chloro cAMP has been shown to have strong anti-cancer effects. This has been shown in the phase II clinical trials this drug has undergone. However, these trials have had issues with solubility and toxicity. The drug is similar to vitamin C and is excreted quickly. Scientists tried to overcome this by using a peristaltic pump to give patients a continuous dosage, but this proved too …
