Squamous cell carcinomas of the head and neck (HNSCC) arise from mucosal keratinocytes of the upper aero-digestive tract. Despite a common cell of origin and similar driver-gene mutations which divert cell fate from differentiation to proliferation, HNSCC are considered a heterogeneous group of tumors categorized by site of origin within the aero-digestive mucosa, and the presence or absence of HPV infection. Tobacco use is a major driver of carcinogenesis in HNSCC and is a poor prognosticator that has previously been associated with poor immune cell infiltration and higher mutation numbers. Here, we study patterns of mutations in HNSCC that are …


Reconciling Incongruencies: Examining The Meaning And Influencing Factors Of Oncology Nurses' Professional Quality Of Life, Rebecca Lynne Boni Dec 2019

Reconciling Incongruencies: Examining The Meaning And Influencing Factors Of Oncology Nurses' Professional Quality Of Life, Rebecca Lynne Boni

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nurses often witness suffering and loss. These experiences are intrinsic to the practice of nursing and can exert a strong, cumulative effect on nurses’ professional quality of life (QOL). Stamm (2010b) conceptualizes professional QOL as a composite of compassion fatigue and compassion satisfaction. Inferior professional QOL has been linked to numerous negative healthcare outcomes. Oncology nurses are particularly vulnerable to compassion fatigue. The Professional Quality of Life Scale (ProQOL), created by Stamm (2009), is the current survey used to measure professional QOL, but it may not be specific enough for oncology nurses.

The purpose of this grounded theory study was …

Disaggregated Hispanic Groups And Cancer: Importance, Methodology, And Current Knowledge, Paulo S. Pinheiro, Karen E. Callahan, Erin N. Kobetz Dec 2019

Disaggregated Hispanic Groups And Cancer: Importance, Methodology, And Current Knowledge, Paulo S. Pinheiro, Karen E. Callahan, Erin N. Kobetz

Environmental & Global Health Faculty Research

Cancer is the leading cause of death among Latinos/Hispanics, the largest racial/ethnic minority group in the United States. Their cancer burden has nearly doubled in 15 years, with 129,000 new cancer cases nationwide in 2014. As this relatively young Hispanic population ages, this burden will inevitably increase; thus, accurate characterization of the Hispanic cancer experience is critical. In this chapter, we summarize the current knowledge on cancer in Hispanics, with a focus on the imperative of disaggregating by specific Hispanic group (Mexicans, Puerto Ricans, Cubans, Central Americans, South Americans, and Dominicans) and nativity. We also describe for the first time …


Metastatic Melanoma Of The Gallbladder Presenting As Polyp In Acute Cholecystitis., Nirvana B Saraswat, William B Devoe Dec 2019

Metastatic Melanoma Of The Gallbladder Presenting As Polyp In Acute Cholecystitis., Nirvana B Saraswat, William B Devoe

Oncology Articles

Malignant melanoma is an aggressive neural crest cell-derived neoplasm with a propensity for metastasis to almost any organ. Gastrointestinal metastasis may manifest as gallbladder polyps. We report a case of metastatic malignant melanoma diagnosed in an 81-year-old male after cholecystectomy performed for acute cholecystitis. Cholecystectomy remains the standard of care for treatment of isolated gallbladder metastasis, especially in the setting of symptomatic disease. Mutation-directed chemotherapeutic and immunotherapeutic modalities serve as efficacious adjunctive therapy in addition to primary surgical resection for this rare condition.

Interaction Of The Oncoprotein Transcription Factor Myc With Its Chromatin Cofactor Wdr5 Is Essential For Tumor Maintenance., Lance R. Thomas, Clare M. Adams, Jing Wang, April M. Weissmiller, Joy Creighton, Shelly L. Lorey, Qi Liu, Stephen W. Fesik, Christine M. Eischen, William P. Tansey

Department of Cancer Biology Faculty Papers

The oncoprotein transcription factor MYC is overexpressed in the majority of cancers. Key to its oncogenic activity is the ability of MYC to regulate gene expression patterns that drive and maintain the malignant state. MYC is also considered a validated anticancer target, but efforts to pharmacologically inhibit MYC have failed. The dependence of MYC on cofactors creates opportunities for therapeutic intervention, but for any cofactor this requires structural understanding of how the cofactor interacts with MYC, knowledge of the role it plays in MYC function, and demonstration that disrupting the cofactor interaction will cause existing cancers to regress. One cofactor …

Optimizing Cancer Cure Dialog: An Analysis Of Pancreatic Cancer Patients' Views Regarding Survival And Cure., Avinoam Nevler, Scott W. Keith, Harish Lavu, Theresa P. Yeo, Shawnna Cannaday, Charles J. Yeo, Jordan M. Winter

Department of Surgery Faculty Papers

BACKGROUND: Pancreatic ductal adenocarcinoma (PDA) is a highly lethal cancer. Clinicians commonly refer to surgical therapy as resection with curative intent. However, PDA cure rates after resection remain unknown and the definition of cure remains vague. We investigated how patients (the majority undergoing resection), family members, and clinicians understand the concept of cure, to better inform discussions with patients regarding PDA prognosis.

METHODS: In a prospective survey, cohorts were asked to indicate the best definition of cure from three choices: 5-year survival endpoint (typically used in the literature), a biological endpoint without biochemical or radiographic signs of disease (similar to …

Ramucirumab: A New Agent For Advanced Or Metastatic Gastric Junction Adenocarcinoma, Adam Smith, Rebecca Worden, Jessica Hoffert, Brendon Rasor, Hannah Stewart, David Koh

Pharmacy and Wellness Review

Ramucirumab (Cyramza®), approved April 21, 2014, is a vascular endothelial growth factor receptor 2 (VEGFR2) antagonist with a U.S. Food and Drug Administration (FDA) indication for the treatment of advanced or metastatic gastric/gastroesophageal junction adenocarcinoma. Gastric cancer is a prevalent cancer in the United States with a poor prognosis. The phase 3 trial, REGARD, shows that ramucirumab, when used within four months after the last dose of first-line chemotherapy or six months after the last dose of adjuvant chemotherapy, increases overall survival. Also, ramucirumab has been included in combination therapy, such as in the RAINBOW trial, which demonstrated its effectiveness …


Management Of Breakthrough Pain In Cancer Patients: Traditional And Novel Approaches, Courtney Porter, Nathaniel Hedrick, Katherine Salay, Lacey Shumate, Caitlin Swann, Kelly Reilly Kroustos Dec 2019

Management Of Breakthrough Pain In Cancer Patients: Traditional And Novel Approaches, Courtney Porter, Nathaniel Hedrick, Katherine Salay, Lacey Shumate, Caitlin Swann, Kelly Reilly Kroustos

Pharmacy and Wellness Review

Approximately 80 percent of career patients experience breakthrough pain (BTP) characterized by acute onset, short duration, and moderate-to-severe intensity. Treatment of BTP using current available medications is often insufficient, leading to the development of various novel approaches that focus on rapid onset of action and short duration of action. Most of these products are still in clinical trials, and future studies are needed to compare the novel approaches to currently available treatments. Non-medication related issues, which arise from a lack of communication and understanding between the patient, physician and pharmacist, are also barriers to adequate BTP management. By educating patients …

Options For Breast Cancer Prevention In High-Risk Patients, Ashley M. Overy, Lacey A. Shumate, Sarah M. Webb, Ashley E. Lehnert, Monica A. Weisenberger, Whitney N. Detillion, Andrew M. Roecker

Pharmacy and Wellness Review

Breast cancer is the most frequently diagnosed non-skin cancer in women, and one in eight women will develop breast cancer within their Iifetimes. Unfortunately, the strongest risk factors for breast cancer (i.e. age, family history, hormonal factors) are not easily modified. There is some evidence that chemopreventative drugs may be able to prevent breast cancer in high-risk patients. Tamoxifen and raloxifene have been shown to reduce the risk of breast cancer in high-risk women but may be associated with several serious adverse events. Clinical trials are currently in progress to determine if aromatase inhibitors are a viable alternative for breast …

Introduction
Across the African Diaspora, hair is synonymous with identity. As such, Black women use a variety of hair products, which often contain more endocrine-disrupting chemicals than products used by women of other races. An emerging body of research is linking chemicals in hair products to breast cancer, but there is no validated instrument that measures constructs related to hair, identity, and breast health. The objective of this study was to develop and validate the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) in a diverse sample of Black women to measure the social and cultural constructs associated …

A Case Of Ccdc6-Ret Fusion Mutation In Adult Acute Lymphoblastic Leukemia (All), A Known Activating Mutation Reported In All, Mateo Mejia Saldarriaga, Amir Steinberg, Eric A. Severson, Adam Binder

Department of Medical Oncology Faculty Papers

We report the case of a patient with B-Cell Acute Lymphoblastic Leukemia (ALL) who was found to harbor a gene fusion involving the CCDC6 and RET genes. Although the RET mutations have been identified before in othermalignancies, and it is thought to represent a driver mutation in these neoplasms, it has yet to be described in ALL. The identification of known fusion genes conferring activating tyrosine kinase activity in neoplasms can suggest potential therapeutic role of tyrosine kinase inhibitors (TKI), an approach that has been exploited in several other fusion genes.

Chronic critical illness is a global clinical issue affecting millions of sepsis survivors annually. Survivors report chronic skeletal muscle weakness and development of new functional limitations that persist for years. To delineate mechanisms of sepsis-induced chronic weakness, we first surpassed a critical barrier by establishing a murine model of sepsis with ICU-like interventions that allows for the study of survivors. We show that sepsis survivors have profound weakness for at least 1 month, even after recovery of muscle mass. Abnormal mitochondrial ultrastructure, impaired respiration and electron transport chain activities, and persistent protein oxidative damage were evident in the muscle of …

Epigenetic Hypomethylation And Upregulation Of Gd3s In Triple Negative Breast Cancer., Wan Li, Xiangjin Zheng, Liwen Ren, Weiqi Fu, Jinyi Liu, Jun Xv, Shiwei Liu, Jinhua Wang, Guanhua Du

Articles, Abstracts, and Reports

Background: Breast cancer remains a major health problem in the world. Triple-negative breast cancer (TNBC) is an aggressive subtype with very poor prognosis. Up to now, the mechanism behind TNBC's activity is still unclear and no candidate drug target has been identified. Thus, it is of critical importance to elucidate the pathways in TNBC and identify the relevant biomarkers. Recent studies showed that ganglioside D3 synthase (GD3s) played a very important role in development of cancers. However, the physiological functions and associated pathways of GD3s in TNBC are still unclear.

Methods:

Results:

Conclusions: In summary, these results suggest that GD3s …

Pediatric Acute Lymphoblastic Leukemia: A Review, Luke Geierman Dec 2019

Pediatric Acute Lymphoblastic Leukemia: A Review, Luke Geierman

Honors Projects

Acute Lymphoblastic Leukemia (ALL) is the most commonly diagnosed pediatric cancer and the most frequent cancer-induced cause of death among young people. Despite this fact, tremendous progress in treating the disease has been made in the last 50 years. This systematic literature review examines the incidence of the disease as well as the importance of risk stratification in treatment planning. The role of genetics in ALL risk stratification, specifically hypodiploidy and hyperdiploidy, is also considered. Finally, current treatment protocols, treatment failure, and the future of research and treatments are all each examined.

Department of Medical Oncology Faculty Papers

NK-cell resistance to transduction is a major technical hurdle for developing NK-cell immunotherapy. By using Baboon envelope pseudotyped lentiviral vectors (BaEV-LVs) encoding eGFP, we obtained a transduction rate of 23.0 ± 6.6% (mean ± SD) in freshly-isolated human NK-cells (FI-NK) and 83.4 ± 10.1% (mean ± SD) in NK-cells obtained from the NK-cell Activation and Expansion System (NKAES), with a sustained transgene expression for at least 21 days. BaEV-LVs outperformed Vesicular Stomatitis Virus type-G (VSV-G)-, RD114- and Measles Virus (MV)- pseudotyped LVs (p < 0.0001). mRNA expression of both BaEV receptors, ASCT1 and ASCT2, was detected in FI-NK and NKAES, with higher expression in NKAES. Transduction with BaEV-LVs encoding for CAR-CD22 resulted in robust CAR-expression on 38.3 ± 23.8% (mean ± SD) of NKAES cells, leading to specific killing of NK-resistant pre-B-ALL-RS4;11 cell line. Using a larger vector encoding a dual CD19/CD22-CAR, we were able to transduce and re-expand dual-CAR-expressing NKAES, even with lower viral titer. These dual-CAR-NK efficiently killed both CD19KO- and CD22KO-RS4;11 cells. Our results suggest that BaEV-LVs may efficiently enable NK-cell biological studies and translation of NK-cell-based immunotherapy to the clinic.

Identification And Molecular Analysis Of Dna In Exosomes, Jena Tavormina Dec 2019

Identification And Molecular Analysis Of Dna In Exosomes, Jena Tavormina

Dissertations and Theses (Open Access)

Exosomes are heterogeneous nanoparticles 50-150nm in diameter. Exosomes contain many functional cargo components, such as protein, DNA, and RNA. While protein and RNA exosome content has been extensively studied, very little work has been done to characterize exosomal DNA. Here, we demonstrate that exosomal DNA is heterogeneous and its packaging into exosomes is dependent on the cell of origin. Furthermore, through a rigorous assessment of various isolation methods, we identify Size Exclusion Chromatography (SEC) as the best method for the isolation of exosomal DNA for downstream applications. Additionally, we evaluate the methylation status of exosomal DNA and demonstrate that exosomal …

Combined Modality Therapies For High-Risk Prostate Cancer: Narrative Review Of Current Understanding And New Directions., Benjamin A. Greenberger, Victor E. Chen, Robert B. Den

Department of Radiation Oncology Faculty Papers

Despite the many prospective randomized trials that have been available in the past decade regarding the optimization of radiation, hormonal, and surgical therapies for high-risk prostate cancer (PCa), many questions remain. There is currently a lack of level I evidence regarding the relative efficacy of radical prostatectomy (RP) followed by adjuvant radiation compared to radiation therapy (RT) combined with androgen deprivation therapy (ADT) for high-risk PCa.
