Ethnic-Specific Predictors Of Neurotoxicity Among Patients With Pediatric Acute Lymphoblastic Leukemia After High-Dose Methotrexate, Rachel D Harris, Melanie Brooke Bernhardt, Mark C Zobeck, Olga A Taylor, Maria Monica Gramatges, Eric S Schafer, Philip J Lupo, Karen R Rabin, Michael E Scheurer, Austin L Brown

Faculty, Staff and Students Publications

High-dose methotrexate (HD-MTX; 5,000 mg/m2) is an important component of curative therapy in many treatment regimens for high-risk pediatric acute lymphoblastic leukemia (ALL). However, methotrexate therapy can result in dose-limiting neurotoxicity which may disproportionately affect Latino children. Thus, we evaluated risk factors for neurotoxicity in an ethnically diverse population of 351 patients (58.1% Latino) who received 1,183 HD-MTX infusions. Overall, thirty-five patients (10%) experienced neurotoxicity, 71% of whom were Latino. After adjusting for clinical risk factors, we found that serum creatinine elevations ≥50% of baseline were associated with a 3-fold increased odds (OR = 3.32, 95% CI: 0.98-11.21, p=0.05) for …

Longitudinal Variations In Antibody Responses Against Sars-Cov-2 Spike Epitopes Upon Serial Vaccinations, Dicle Yalcin, Sydney J. Bennett, Jared Sheehan, Amber J. Trauth, For Yue Tso, John T. West, Michael E. Hagensee, Alistair J. Ramsay, Charles Wood

LSU-LCMC Cancer Center Faculty Publications

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impacted healthcare, the workforce, and worldwide socioeconomics. Multi-dose mono- or bivalent mRNA vaccine regimens have shown high efficacy in protection against SARS-CoV-2 and its emerging variants with varying degrees of efficacy. Amino acid changes, primarily in the receptor-binding domain (RBD), result in selection for viral infectivity, disease severity, and immune evasion. Therefore, many studies have centered around neutralizing antibodies that target the RBD and their generation achieved through infection or vaccination. Here, we conducted a unique longitudinal study, analyzing the effects of a three-dose mRNA vaccine regimen …

Mechanisms Of Chromosomal Instability (Cin) Tolerance In Aggressive Tumors: Surviving The Genomic Chaos, Brittiny Dhital, Veronica Rodriguez-Bravo

Student Papers, Posters & Projects

Chromosomal instability (CIN) is a pervasive feature of human cancers involved in tumor initiation and progression and which is found elevated in metastatic stages. CIN can provide survival and adaptation advantages to human cancers. However, too much of a good thing may come at a high cost for tumor cells as excessive degree of CIN-induced chromosomal aberrations can be detrimental for cancer cell survival and proliferation. Thus, aggressive tumors adapt to cope with ongoing CIN and most likely develop unique susceptibilities that can be their Achilles' heel. Determining the differences between the tumor-promoting and tumor-suppressing effects of CIN at the …

Met Alterations Are Associated With Osimertinib Resistance In Egfr Mutant Lung Cancers, A Meta-Analysis, Annie Le, Marissa Viola, Jun Wang

Research Day

Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) that has been used to treat EGFR mutant lung cancers, especially those with EGFR T790M mutation. Resistance to osimertinib is likely associated with acquired genetic alterations in these cancer cells. Mesenchymal epithelial transition (MET) is a tyrosine kinase and its amplification is frequently seen in osimertinib resistant patients. To investigate whether the presence of MET alteration is associated with osimertinib resistance, a meta-analysis was conducted using published observations of EGFR mutant lung cancer patients treated with osimertinib. Frequencies of MET alterations are variable, ranging from 0-43% in osimertinib resistant patients. MET alteration …

Serinc5 Restricts Hiv Membrane Fusion By Altering Lipid Order And Heterogeneity In The Viral Membrane, Amanda E Ward, Daria Sokovikova, Melvin Neal Waxham, Frederick A Heberle, Ilya Levental, Kandice R Levental, Volker Kiessling, Judith M White, Lukas K Tamm

Faculty, Staff and Student Publications

The host restriction factor, Serinc5, incorporates into budding HIV particles and inhibits their infection by an incompletely understood mechanism. We have previously reported that Serinc5 but not its paralogue, Serinc2, blocks HIV cell entry by membrane fusion, specifically by inhibiting fusion pore formation and dilation. A body of work suggests that Serinc5 may alter the conformation and clustering of the HIV fusion protein, Env. To contribute an additional perspective to the developing model of Serinc5 restriction, we assessed Serinc2 and Serinc5's effects on HIV pseudoviral membranes. By measuring pseudoviral membrane thickness via cryo-electron microscopy and order via the fluorescent dye, …

Bayesian Adaptive Model Selection Design For Optimal Biological Dose Finding In Phase I/Ii Clinical Trials, Ruitao Lin, Guosheng Yin, Haolun Shi

Faculty, Staff and Student Publications

Identification of the optimal dose presents a major challenge in drug development with molecularly targeted agents, immunotherapy, as well as chimeric antigen receptor T-cell treatments. By casting dose finding as a Bayesian model selection problem, we propose an adaptive design by simultaneously incorporating the toxicity and efficacy outcomes to select the optimal biological dose (OBD) in phase I/II clinical trials. Without imposing any parametric assumption or shape constraint on the underlying dose-response curves, we specify curve-free models for both the toxicity and efficacy endpoints to determine the OBD. By integrating the observed data across all dose levels, the proposed design …

The Abscopal Effect In Patients With Cancer Receiving Immunotherapy, Blessie Elizabeth Nelson, Jacob J Adashek, Steven H Lin, Vivek Subbiah

Faculty, Staff and Student Publications

Interest in the abscopal effect has been rekindled over the past decade with the advent of immunotherapy. Although purportedly elusive, this phenomenon is being increasingly reported. Venturing further using a multimodality approach with an array of systemic agents and unconventional modalities is direly needed. In this perspective, we describe the fundamentals of abscopal responses (ARs), explore combinations with systemic therapies that hold promise in eliciting ARs, and reconnoiter unconventional modalities that may induce ARs. Finally, we scrutinize prospective agents and modalities that exhibit preclinical ability to elicit ARs and discuss prognostic biomarkers, their limitations, and pathways of abscopal resistance for …

Feature Selection For Support Vector Regression Using A Genetic Algorithm, Shannon B Mckearnan, David M Vock, G Elisabeta Marai, Guadalupe Canahuate, Clifton D Fuller, Julian Wolfson

Faculty, Staff and Student Publications

Support vector regression (SVR) is particularly beneficial when the outcome and predictors are nonlinearly related. However, when many covariates are available, the method's flexibility can lead to overfitting and an overall loss in predictive accuracy. To overcome this drawback, we develop a feature selection method for SVR based on a genetic algorithm that iteratively searches across potential subsets of covariates to find those that yield the best performance according to a user-defined fitness function. We evaluate the performance of our feature selection method for SVR, comparing it to alternate methods including LASSO and random forest, in a simulation study. We …

Mmp9 Clears The Way For Metastatic Cell Penetration Across The Blood-Brain Barrier, Joseph H Mccarty

Faculty, Staff and Student Publications

Although brain metastases are 10-fold more prevalent than primary brain cancers, relatively little is understood about the genes and pathways that promote metastatic cell entry, growth, and survival in the brain. Hence, determining how metastatic tumors colonize the brain and thrive within the neural microenvironment is a topic of both fundamental importance and direct clinical relevance. In this issue, a report by Karreman and colleagues explores pathways that are exploited by metastatic tumor cells to arrest in the circulation, cross the endothelial blood-brain barrier (BBB), and thrive in the brain microenvironment. The authors used elegant imaging tools including intravital fluorescence …

Pectoralis Nerve Block Compared To Thoracic Paravertebral Nerve Block In The Mastectomy Patient: Evidence-Based Practice Recommendations, Eric Boyer

Doctor of Nursing Practice Scholarly Projects

Patients undergoing a mastectomy are at increased risk of becoming opioid dependent. Most patients undergoing a mastectomy are diagnosed with breast cancer, and the use of opioids is known to aid in cancer metastasizing due to the suppression of the body's natural killer cells. In addition, regional anesthesia, also known as a nerve block, has long provided a reduction in sensation by blocking the nerve pathway, thus numbing the feeling of pain in the operative area. The Pectoralis nerve block (PECS) and the Thoracic Paravertebral block (TPVB) are used in patients undergoing a mastectomy to help reduce the severity of …

Ewing Sarcoma (EWS) is the second most common osseous malignancy in children and young adults after osteosarcoma, while it is the fifth common osseous malignancy within adult age population. The clinical presentation of EWS is quite often non-specific, with the most common symptoms at presentation consisting of pain, swelling or general discomfort. The dearth of clinically relevant diagnostic or predictive biomarkers continues to remain a pressing clinical challenge. Identification of tumor specific biomarkers can lend towards an early diagnosis, expedited initiation of therapy, monitoring of therapeutic response, and early detection of recurrence of disease. We carried-out a complex analysis of …

The challenge of eradicating leukemia in patients with acute myelogenous leukemia (AML) after initial cytoreduction has motivated modern efforts to combine synergistic active modalities including immunotherapy. Recently, the ETCTN/CTEP 10026 study tested the combination of the DNA methyltransferase inhibitor decitabine together with the immune checkpoint inhibitor ipilimumab for AML/myelodysplastic syndrome (MDS) either after allogeneic hematopoietic stem cell transplantation (HSCT) or in the HSCT-naïve setting. Integrative transcriptome-based analysis of 304 961 individual marrow-infiltrating cells for 18 of 48 subjects treated on study revealed the strong association of response with a high baseline ratio of T to AML cells. Clinical responses were …

Pancreatic Cancer: Advances And Challenges, Christopher J Halbrook, Costas A Lyssiotis, Marina Pasca Di Magliano, Anirban Maitra

Faculty, Staff and Student Publications

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers. Significant efforts have largely defined major genetic factors driving PDAC pathogenesis and progression. Pancreatic tumors are characterized by a complex microenvironment that orchestrates metabolic alterations and supports a milieu of interactions among various cell types within this niche. In this review, we highlight the foundational studies that have driven our understanding of these processes. We further discuss the recent technological advances that continue to expand our understanding of PDAC complexity. We posit that the clinical translation of these research endeavors will enhance the currently dismal survival rate of this recalcitrant …

The Role Of Extracellular Vesicles In Cancer, Raghu Kalluri, Kathleen M Mcandrews

Faculty, Staff and Student Publications

Intercellular communication is a key feature of cancer progression and metastasis. Extracellular vesicles (EVs) are generated by all cells, including cancer cells, and recent studies have identified EVs as key mediators of cell-cell communication via packaging and transfer of bioactive constituents to impact the biology and function of cancer cells and cells of the tumor microenvironment. Here, we review recent advances in understanding the functional contribution of EVs to cancer progression and metastasis, as cancer biomarkers, and the development of cancer therapeutics.

Faculty, Staff and Student Publications

Since the discovery of the first microRNAs (miRNAs, miRs), the understanding of miRNA biology has expanded substantially. miRNAs are involved and described as master regulators of the major hallmarks of cancer, including cell differentiation, proliferation, survival, the cell cycle, invasion, and metastasis. Experimental data indicate that cancer phenotypes can be modified by targeting miRNA expression, and because miRNAs act as tumor suppressors or oncogenes (oncomiRs), they have emerged as attractive tools and, more importantly, as a new class of targets for drug development in cancer therapeutics. With the use of miRNA mimics or molecules targeting miRNAs (i.e., small-molecule inhibitors such …

Targeting Of Epigenetic Co-Dependencies Enhances Anti-Aml Efficacy Of Menin Inhibitor In Aml With Mll1-R Or Mutant Npm1, Warren Fiskus, Christopher P Mill, Christine Birdwell, John A Davis, Kaberi Das, Steffen Boettcher, Tapan M Kadia, Courtney D Dinardo, Koichi Takahashi, Sanam Loghavi, Michael J Soth, Tim Heffernan, Gerard M Mcgeehan, Xinjia Ruan, Xiaoping Su, Christopher R Vakoc, Naval Daver, Kapil N Bhalla

Monotherapy with Menin inhibitor (MI), e.g., SNDX-5613, induces clinical remissions in patients with relapsed/refractory AML harboring MLL1-r or mtNPM1, but most patients either fail to respond or eventually relapse. Utilizing single-cell RNA-Seq, ChiP-Seq, ATAC-Seq, RNA-Seq, RPPA, and mass cytometry (CyTOF) analyses, present pre-clinical studies elucidate gene-expression correlates of MI efficacy in AML cells harboring MLL1-r or mtNPM1. Notably, MI-mediated genome-wide, concordant, log2 fold-perturbations in ATAC-Seq and RNA-Seq peaks were observed at the loci of MLL-FP target genes, with upregulation of mRNAs associated with AML differentiation. MI treatment also reduced the number of AML cells expressing the stem/progenitor cell signature. A …

Immune checkpoint therapy (ICT) has dramatically altered clinical outcomes for cancer patients and conferred durable clinical benefits, including cure in a subset of patients. Varying response rates across tumor types and the need for predictive biomarkers to optimize patient selection to maximize efficacy and minimize toxicities prompted efforts to unravel immune and non-immune factors regulating the responses to ICT. This review highlights the biology of anti-tumor immunity underlying response and resistance to ICT, discusses efforts to address the current challenges with ICT, and outlines strategies to guide the development of subsequent clinical trials and combinatorial efforts with ICT.

A Scoping Review Of Microwave Ablation Versus Partial Nephrectomy For Treatment Of Renal Cell Carcinoma, Benjamin Odumah

Master of Science in Applied Health Economics and Outcomes Research Capstone Presentations

Renal cell carcinomas (RCC) make up 80 to 85% of primary renal neoplasms. Over 90% are low grade and slow growing with low probability of metastasis. Advantages of percutaneous techniques including microwave ablation (MWA) over surgical approach such as partial nephrectomy (PN), including cost effectiveness, minimally invasive, better renal preservation rates, lower procedure-related morbidity, and reduced hospitalization time make the case compelling. The major limitations for MWA are lack of prospective RCT or long-term follow-up data. The objective of this capstone was to conduct a scoping review on MWA versus PN regarding oncologic, perioperative, and functional outcomes in the treatment …
