The Effects Of Chemotherapeutic Agents On Cognitive Function: A Literature Review, Corinne Menz

The Eleanor Mann School of Nursing Undergraduate Honors Theses

With increasing cancer diagnoses and an increase of chemotherapy treatment, many patients complain of cognitive decline during the duration of treatment as well as once treatment has been completed. The purpose of this review is to compile relevant research regarding chemotherapy-related cognitive impairment and its implications for the care of cancer patients. Peer-reviewed articles and studies focusing on the impact of chemotherapy on cognitive function were evaluated, resulting in a total of 12 studies utilized in this review. Overall, it has been found that a large percentage of patients undergoing chemotherapy treatment report a subjective decline in cognitive functioning, but ...

Non-Selective Primary Human Tumor Cell Line Generation From Surgical Resections To Be Paired With Flash Frozen And Paraffin Embedded Tissue: Advancements In Democratizing Translational Research Materials To Rural Institutions, Jennifer Hawkins, Rebecca Russell, Logan M. Lawrence, Amrita Valluri, Jessica Wellman, Krista Denning

Marshall Journal of Medicine

Translational cancer research relies on the availability of human patient tissue demonstrating the specific disease process under investigation. Biobanks of human tissue have historically been and remain to date the primary access point for cancer research samples. Biorepositories routinely supply researchers with varying sample types for use in biomedical studies; most commonly formalin-fixed and paraffin-embedded (FFPE) tissue, or fresh snap-frozen tissue. In conjunction with preserved tissue samples, viable tumor cell lines derived from patient tissue have emerged to be a new gold standard in cancer research particularly in drug discovery and functional prognostic assays. Tissue banks providing these samples are ...

Pheochromocytoma Presenting As Testicular Pain: An Unusual Case Report, Jinal K. Patel, Varun Reddy, Gauthier L. Stepman, Debra Angelo, Johnathan Frunzi

Endocrinology

Pheochromocytoma (PCC) is a rare catecholamine-secreting tumor that arises from chromaffin cells of the adrenal medulla which are derived from the neural crest. This report illustrates a 51-year-old Caucasian male with a history of hypertension diagnosed two years ago who presented to the hospital due to acute onset of right testicular pain of 3-day duration. Laboratory results and imaging revealed a presumptive diagnosis of PCC. The patient had undergone robot-assisted laparoscopic right adrenalectomy 14 days after being diagnosed with PCC due to perioperative management with phenoxybenzamine. The final pathology report revealed a PCC. At follow-up two weeks after discharge, the ...

Racial And Ethnic Disparities In Illinois Lung Cancer Incidence, Mortality Stage At Diagnosis, Surgical Treatment, And Screening, Ritika Golechha, Mickyas Hezekiel Eskender, David D. Odell, Joe Feinglass

Journal of Health Disparities Research and Practice

This study analyzes the extent of racial and ethnic disparities in lung cancer in Illinois as compared to national trends. Cancer registry data were used to compare lung cancer incidence, mortality and stage at diagnosis rates for non-Hispanic (NH) white, NH Black and Hispanic Illinois residents. Hospital discharge data were used to compare medical and surgical admission and screening rates. Smoking across race and ethnic groups was compared using data from the Illinois Behavioral Risk Factor Surveillance System to determine the extent to which disparities might be related to smoking prevalence. Rate ratios for NH Black and Hispanics compared to ...

The Heme-Regulated Inhibitor Pathway Modulates Susceptibility Of Poor Prognosis B-Lineage Acute Leukemia To Bh3-Mimetics, Kaitlyn Hill Smith

Theses and Dissertations (ETD)

Anti-apoptotic MCL1 is one of the most frequently amplified genes in human cancers and its elevated expression confers resistance to many therapeutics including the BH3-mimetic agents ABT-199 and ABT-263. The anti-malarial, dihydroartemisinin (DHA) translationally represses MCL-1 and synergizes with BH3-mimetics. To explore how DHA represses MCL-1, a genome-wide CRISPR screen identified that loss of genes in the heme synthesis pathway renders mouse BCR-ABL+ B-ALL cells resistant to DHA-induced death. Mechanistically, DHA disrupts the interaction between heme and the eIF2α kinase heme regulated inhibitor (HRI) triggering the integrated stress response. Genetic ablation of Eif2ak1, which encodes HRI, blocks MCL-1 repression in ...

Pancoast Syndrome Due To High Grade Anaplastic Tumor, Christian Almanzar, Seth Maxwell, Mauricio Gomez, Omar Ansari, Luis Silva

HCA Healthcare Journal of Medicine

The Pancoast tumor is an uncommon type of lung cancer that arises from within the superior sulcus. With most clinical manifestations occurring due to mass effect, Pancoast syndrome is a known complication that includes shoulder and arm musculoskeletal pain, Horner’s syndrome and neurological complications of the upper extremities, including weakness and atrophy. Even though adenocarcinoma is the most common cause of Pancoast syndrome among lung cancers, other malignancies can be responsible as well. Treatment is similar to that of other standard NSCLC treatments that include chemotherapy, radiation, immunotherapy and surgery. Here we report a patient with Pancoast syndrome secondary ...

Esophageal Cancer Complicated By A Distal Acquired Esophagopulmonary Fistula, Alexander D. Lake, Yousef Almuzaini, Aaron Jaffe, Joseph Staffetti, Mukesh Patel

HCA Healthcare Journal of Medicine

Esophageal respiratory fistulas, commonly found as a tracheoesophageal fistula (TEF), are abnormal connections between the esophagus and trachea. These can be congenital (infants) or acquired (malignancy). A more rare form of an esophageal respiratory fistula is an abnormal connection between the esophagus and the lung parenchyma—also known as an esophagopulmonary fistula. In our case, we present a middle-aged male with a history of esophageal cancer undergoing chemotherapy and radiation presenting into the intensive care unit for increasing shortness of breath and vomiting after eating found to have a rare form of a TEF causing his symptoms.

Xct-Driven Expression Of Gpx4 Determines Sensitivity Of Breast Cancer Cells To Ferroptosis Inducers, Namgyu Lee, Anne E. Carlisle, Austin Peppers, Sung Jin Park, Mihir B. Doshi, Meghan E. Spears, Dohoon Kim

Open Access Publications by UMMS Authors

Inducers of ferroptosis such as the glutathione depleting agent Erastin and the GPX4 inhibitor Rsl-3 are being actively explored as potential therapeutics in various cancers, but the factors that determine their sensitivity are poorly understood. Here, we show that expression levels of both subunits of the cystine/glutamate antiporter xCT determine the expression of GPX4 in breast cancer, and that upregulation of the xCT/selenocysteine biosynthesis/GPX4 production axis paradoxically renders the cancer cells more sensitive to certain types of ferroptotic stimuli. We find that GPX4 is strongly upregulated in a subset of breast cancer tissues compared to matched normal ...

Cohesin Mutations Alter Dna Damage Repair And Chromatin Structure And Create Therapeutic Vulnerabilities In Mds/Aml, Zuzana Tothova, Anne-Laure Valton, Sergey V. Venev, Job Dekker, Benjamin L. Ebert

Open Access Publications by UMMS Authors

The cohesin complex plays an essential role in chromosome maintenance and transcriptional regulation. Recurrent somatic mutations in the cohesin complex are frequent genetic drivers in cancer, including myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Here, using genetic dependency screens of stromal antigen 2-mutant (STAG2-mutant) AML, we identified DNA damage repair and replication as genetic dependencies in cohesin-mutant cells. We demonstrated increased levels of DNA damage and sensitivity of cohesin-mutant cells to poly(ADP-ribose) polymerase (PARP) inhibition. We developed a mouse model of MDS in which Stag2 mutations arose as clonal secondary lesions in the background of clonal hematopoiesis driven ...

Physical Activity, Mental Health, And Technology Preferences To Support Cancer Survivors During The Covid-19 Pandemic: Cross-Sectional Study, Jamie Faro, Kristin M. Mattocks, Catherine S. Nagawa, Stephenie C. Lemon, Bo Wang, Sarah L. Cutrona, Rajani S. Sadasivam

COVID-19 Publications by UMMS Authors

BACKGROUND: COVID-19 has had significant health-related and behavioral impacts worldwide. Cancer survivors (hereafter referred to as "survivors") are particularly prone to behavioral changes and are encouraged to be more vigilant and observe stricter social distancing measures.

OBJECTIVE: We explored (1) changes in physical activity and sedentary behaviors since the onset of COVID-19, along with changes in mental health status, and (2) alternative strategies to support survivors' physical activity and social health during and after COVID-19, along with the role of digital health in such strategies.

METHODS: A questionnaire was distributed among survivors participating (currently or previously) in the community-based physical ...

Use Of Prame Immunostaining To Distinguish Melanoma In Situ From Lentigo Senilis, Hailey Olds, Sarah Utz, Darius Mehregan

Medical Student Research Symposium

PRAME (PReferentially expressed Antigen in MElanoma) is an antigen that is expressed by malignant cells in melanoma, as well as other cancers such as breast carcinoma, renal cell carcinoma, and leukemia. PRAME immunohistochemistry has proved effective in identifying malignant melanocytes in melanoma lesions, but it is unclear if it may be used to distinguish melanoma from benign melanocytic conditions, such as lentigo senilis. In particular, melanoma in situ may be confused with lentigo senilis clinically and histologically, thus PRAME immunostaining is potentially useful for differentiating these two lesions. We evaluated 31 samples of lentigo senilis, 26 of melanoma in situ ...

Nad(H) Phosphates Mediate Tetramer Assembly Of Human C-Terminal Binding Protein (Ctbp), Jeffry C. Nichols, Celia A. Schiffer, William E. Royer

University of Massachusetts Medical School Faculty Publications

C-terminal binding proteins (CtBPs) are co-transcriptional factors that play key roles in cell fate. We have previously shown that NAD(H) promotes the assembly of similar tetramers from either human CtBP1 and CtBP2 and that CtBP2 tetramer destabilizing mutants are defective for oncogenic activity. To assist structure-based design efforts for compounds that disrupt CtBP tetramerization, it is essential to understand how NAD(H) triggers tetramer assembly. Here, we investigate the moieties within NAD(H) that are responsible for triggering tetramer formation. Using multi-angle light scattering (MALS) we show that ADP is able to promote tetramer formation of both CtBP1 and ...

Clinical Utility Of Molecular Profiling In Recurrent Glioblastoma Multiforme, Rebecca P. Bystrom, Pavalan Selvam, Jens Rueter, Honey Reddi, Christine Lu-Emerson

Journal of Maine Medical Center

Introduction: Glioblastoma multiforme (GBM) is the most common and aggressive primary malignant brain tumor found in adults. GBM has limited therapeutic options. Initial tumor sampling establishes the histopathologic diagnosis, identifies prognostic and therapeutic biomarkers, and provides an opportunity for molecular profiling. By contrast, the utility of repeat tumor sampling and molecular profiling in recurrent GBM is not well established.

Clinical Findings: We present a 69-year-old woman with GBM whose tumor recurred after standard treatment with temozolomide (TMZ) and concurrent radiation, followed by adjuvant TMZ. This patient had a methylated O6-methylguanine-DNA methyltransferase (MGMT) promoter, which ordinarily predicts a favorable response to ...

Stat5a Regulation By Serine Phosphorylation In Breast Cancer, Alicia E. Woock

Theses and Dissertations

The neuroendocrine hormone prolactin (PRL) and its cognate receptor (PRLr) have been implicated in the pathogenesis of breast cancer. PRL signaling relies on activating kinases such as the tyrosine kinase Jak2 and serine/threonine kinases ERK1/2, NEK3, PI3K, and AKT. In the canonical pathway of PRL signaling, JAK2 phosphorylates the transcription factor STAT5a at tyrosine residue 694 (pY694-STAT5a), preceding STAT5a nuclear translocation and transcriptional activity. However, STAT5a exists with functional duality as a transcription factor, having both pro-differentiative and pro-proliferative target genes. Other STAT family members (STATs 1, 3, and 6) have been shown to have transcriptional activity in ...

Goblet Cell Carcinoma Of The Appendix: A Case Report On Goblet Cell Carcinoid, Sheliza Kabani, Aubtin Saedi, Austin Lehr, Lina O'Brien

HCA Healthcare Journal of Medicine

Goblet cell carcinoid of the appendix is a rare neoplasm with histological features of both neuroendocrine and adenocarcinomas. The combination of its aggressive behavior, infrequent occurrence, and variable clinical presentation convolutes the management of this tumor. We report the case of a 75-year-old female presenting with acute appendicitis. A laparoscopic appendectomy was performed. The pathology report showed goblet cell carcinoid at the base of the appendix with involvement of the proximal surgical margins. At her postoperative visit, the patient’s pathology report and options for management were reviewed, and the patient agreed to proceed with a right hemicolectomy 8-10 weeks ...

Molecular Analysis Of A Rare Case Of Low-Grade Primary Peritoneal Serous Carcinoma In A Male, Vladislav V. Makarenko, Dina Kandil, Ediz F. Cosar, Lloyd Hutchinson, Ashraf Khan

Open Access Publications by UMMS Authors

Primary peritoneal serous carcinomas (PPSC) are exceedingly rare in male patients. Only a few cases were reported, and mostly with the limited immunophenotypical characterization. No molecular analysis of PPSC in males has been previously performed. We here describe another case of PPSC in a male patient. A comprehensive molecular analysis of the tumor revealed SF3B1 gene mutation as a possible driver.
