Hdr Brachytherapy For Skin Cancer Using H.A.M. Applicator, Timothy Richard Thatcher May 2020

Hdr Brachytherapy For Skin Cancer Using H.A.M. Applicator, Timothy Richard Thatcher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Skin cancer is the most common type of malignancy affecting both men and women in the United States. A majority of these cases are nonmelanoma skin cancers (NMSC) such as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The goal of any skin cancer treatment is to cure the lesion itself while also preserving function and optimizing superficial cosmesis. High dose rate (HDR) brachytherapy provides an alternative to superficial x-ray or electron beam for skin cancer treatment. Utilizing an Iridium 192 source soldered to the end of a wire, surface dose can be administered at predetermined positions with sharper …

Analysis Of Gene Expression In Early-Stage Pancreatic Cancer And Investigation Of 1,2,3,4,6-Penta-O-Galloyl-Β-D-Glucopyranoside As A Therapeutic, Zachary R. Heinzman

Honors Program Theses

Pancreatic cancer (PC) is one of the deadliest cancers among both men and women. However, if it is detected early, there is a significant increase in the 5-year survivability of the disease1 . Currently, there are no truly efficient detection mechanisms available to detect earlystage PC when treatment options are more viable. The first objective of this project was to determine the expression levels of AHNAK2, IGHG3, EPPK1, CTHRC1, CEL, PLA2G1B, and GNMT—all known to be aberrantly expressed in PC cell lines—in early-stage PC tissue and assess the feasibility of their use as potential biomarkers for PC. To accomplish this, …

Assessing Patient Attitudes To Ward Genetic Testing For Hereditary Hematologic Malignancy, Addison Johnson May 2020

Assessing Patient Attitudes To Ward Genetic Testing For Hereditary Hematologic Malignancy, Addison Johnson

Dissertations and Theses (Open Access)

Since 2003, more than 15 genes have been identified to predispose to hereditary hematologic malignancy (HHM). Although the diagnostic yield of germline analysis for leukemia is similar to solid tumors, referral for genetic evaluation in adults with leukemia is underperformed. Identifying HHM is important for prognostication, treatment, and donor selection for hematopoietic stem cell transplant. No studies have examined leukemia patients’ attitudes toward genetic testing for HHM. This study aimed to assess leukemia patients’ attitudes toward genetic testing and elicit current perceived distress due to a leukemia diagnosis. Data were elicited through an electronic survey sent to 5,513 patients diagnosed …


Genetic Counselors' Approaches To Direct-To-Consumer Genetic Testing For Hereditary Breast Cancer, Sarah Burke May 2020

Genetic Counselors' Approaches To Direct-To-Consumer Genetic Testing For Hereditary Breast Cancer, Sarah Burke

Dissertations and Theses (Open Access)

Given the increasing availability of health-related direct-to-consumer genetic testing (DTC-GT) and third-party interpretation (TPI) services, it is likely that genetic counselors (GCs) will continue to encounter consumers that require follow-up counseling for their results. The National Comprehensive Cancer Network recommends clinical-grade genetic testing to confirm commercial results; however, the type of testing that GCs select remains uncharacterized. Therefore, we aimed to describe the specific recommendations that cancer GCs make for confirmatory genetic testing in probands who have already obtained DTC-GT results or TPI data that reported a BRCA1/2 pathogenic variant. We recruited 80 GCs specializing in hereditary cancer and administered …

Modulation Of Pi3k-Akt Pathway In Colorectal Cancer, Maliha Nusrat

Dissertations and Theses (Open Access)

The phosphatidylinositol-3-kinase (PI3K) signaling pathway is activated in 20-40% colorectal cancers (CRC) through PTEN loss (PTENloss) and PIK3CA mutations (PIK3CAmut). Allosteric AKT inhibition with MK2206 monotherapy has been ineffective in CRC patients. We investigated the impact of MK2206 on pharmacodynamic (PD) markers and signaling pathways using reverse phase protein array (RPPA) on (1) paired tumor biopsies from a clinical trial of MK2206 in PI3K-altered metastatic CRC, (2) PTENlossCRC patient derived xenografts (PDX) treated with MK2206 or carrier, and (3) MK2206-treated cell lines. PD inhibition was deep in cell lines, less but significant in …

Faculty, Staff and Student Publications

The majority of clinically diagnosed cutaneous T‐cell lymphomas (CTCL) highly express the cell‐surface markers CC chemokine receptor 4 (CCR4) and/or CD25. Recently, we have developed diphtheria toxin‐based recombinant Ontak®‐like human IL2 fusion toxin (IL2 fusion toxin) and anti‐human CCR4 immunotoxin (CCR4 IT). In this study, we first compared the efficacy of the CCR4 IT vs IL2 fusion toxin for targeting human CD25+CCR4+ CTCL. We demonstrated that CCR4 IT was more effective than IL2 fusion toxin. We further constructed an IL2‐CCR4 bispecific IT. The bispecific IT was significantly more effective than either IL2 fusion toxin or CCR4 IT alone. The bispecific …

Faculty, Staff and Students Publications

BACKGROUND: Since 1979, mortality from hepatocellular cancer (HCC) has doubled in the United States (US). Lifesaving drugs, prohibitively expensive for some, were approved and marketed to treat hepatitis C virus (HCV), a major risk factor for HCC, beginning in 1997. After the prior introduction of other lifesaving innovations, including active retroviral drug therapy for human immunodeficiency virus and surfactant for respiratory distress syndrome of the newborn, racial inequalities in their mortalities increased in the US. In this descriptive study, we explored racial inequalities in mortality from HCC before and after licensure of HCV drugs in the US.

METHODS: The US …

Faculty, Staff and Students Publications

BACKGROUND: Aberrant activation of DNA damage response (DDR) is a major cause of chemoresistance in colorectal cancer (CRC). CHK1 is upregulated in CRC and contributes to therapeutic resistance. We investigated the upstream signaling pathways governing CHK1 activation in CRC.

METHODS: We identified CHK1-binding proteins by mass spectrometry analysis. We analyzed the biologic consequences of knockout or overexpression of TRAF4 using immunoblotting, immunoprecipitation, and immunofluorescence. CHK1 and TRAF4 ubiquitination was studied in vitro and in vivo. We tested the functions of TRAF4 in CHK1 phosphorylation and CRC chemoresistance by measuring cell viability and proliferation, anchorage-dependent and -independent cell growth, and mouse …

Transcriptional Upregulation Of Nlrc5 By Radiation Drives Sting- And Interferon-Independent Mhc-I Expression On Cancer Cells And T Cell Cytotoxicity., Lauren Zebertavage, Alejandro F Alice, Marka R Crittenden, Michael J. Gough

Articles, Abstracts, and Reports

Radiation therapy has been shown to enhance the efficacy of various T cell-targeted immunotherapies that improve antigen-specific T cell expansion, T regulatory cell depletion, or effector T cell function. Additionally, radiation therapy has been proposed as a means to recruit T cells to the treatment site and modulate cancer cells as effector T cell targets. The significance of these features remains unclear. We set out to determine, in checkpoint inhibitor resistant models, which components of radiation are primarily responsible for overcoming this resistance. In order to model the vaccination effect of radiation, we used a Listeria monocytogenes based vaccine to …

Finding Common Threads: How Patients, Physicians And Nurses Perceive The Patient Gown, Christy M. Lucas, Cheryl Dellasega Apr 2020

Finding Common Threads: How Patients, Physicians And Nurses Perceive The Patient Gown, Christy M. Lucas, Cheryl Dellasega

Patient Experience Journal

Evidence-based care is standard practice in medicine, but the patient gown has fallen outside the scope of scholarly research. The current gown renders a patient vulnerable, diminishing patients’ sense of identity, agency, and dignity with its one-size-fits-none design. The impact on providers is similarly neglected. Our objective was to explore how patients and providers derive meaning from patient gowns. A convenience sample at an academic medical center was interviewed utilizing a standardized framework developed by a medical student and two PhD-prepared researchers with experience in qualitative methods. The study was inductive in nature, seeking to understand perceptions of the patient …

Capecitabine, a prodrug of fluorouracil, is a component of many chemotherapy regimens used to treat a wide variety of malignancies. One of the most common adverse reactions experienced by those who have been exposed to capecitabine is palmar-plantar erythrodysesthesia (PPE). PPE is a cutaneous manifestation of chemotherapy-related drug toxicity that has signs and symptoms of erythema, edema, pain, ulceration, or desquamation of the palms of the hands and soles of the feet. The signs and symptoms occur with varying severity. There are few reports of the genitalia being similarly affected. The following case describes a patient with locally advanced rectal …


Genetic Relationships And Therapeutic Options For Relapsed Acute Lymphoblastic Leukemia, Hailie Shertzer Apr 2020

Genetic Relationships And Therapeutic Options For Relapsed Acute Lymphoblastic Leukemia, Hailie Shertzer

Senior Honors Theses

Acute lymphoblastic leukemia (ALL) is the most common form of cancer among children and can be lethal to the adult population. Though 80% of patients with ALL reach complete remission after treatment, about 20% of those diagnosed fail to remain cancer-free. Genetic rearrangements are the hallmark of relapsed ALL, but the mechanism by which these rearrangements occur is still unclear. Recent research suggests these mutations may be detectable during initial diagnosis. If researchers are able to accurately assess the probability of relapse during diagnosis by analyzing the genome of the leukemic cells, the likelihood of administering effective therapy would increase. …

Articles, Abstracts, and Reports

5-Fluorouracil (5-FU) is a chemotherapeutic drug widely used to treat colorectal cancer. 5-FU is known to gradually lose its efficacy in treating colorectal cancer following the acquisition of resistance. We investigated the mechanism of 5-FU resistance using comprehensive lipidomic approaches. We performed lipidomic analysis on 5-FU-resistant (DLD-1/5-FU) and -sensitive (DLD-1) colorectal cancer cells using MALDI-MS and LC-MRM-MS. In particular, sphingomyelin (SM) species were significantly up-regulated in 5-FU-resistant cells in MALDI-TOF analysis. Further, we quantified sphingolipids including SM and Ceramide (Cer) using Multiple Reaction Monitoring (MRM), as they play a vital role in drug resistance. We found that 5-FU resistance in …

Duodenal Carcinoid Tumour – A Case Report, Vasile Negrean, Cristina Buchman, Mirela Georgiana Perne, Mircea Milaciu, Iacob Domsa, Teodora Gabriela Alexescu, Ioana Para, Olga Hilda Orasan

Journal of Mind and Medical Sciences

Duodenal carcinoids are rare tumours of the small intestine with heterogenous clinical and pathological characteristics. The long-term prognosis is very good if discovered in the early stages. We present the case of a patient with a non-functional duodenal carcinoid tumour discovered incidentally during an upper gastrointestinal endoscopy. The diagnosis was confirmed through immunohistochemistry. Treatment consisted of the endoscopic resection of the tumour and the surveillance of the patient for the following 2 years, with no signs of recurrence. We have conducted a literature review regarding the clinical manifestations, diagnosis, treatment, and follow-up of patients with this type of tumours.
