Single Dose Nivolumab And Ipilimumab Treatment Causing Complete And Durable Response In Extensive Stage - Small Cell Lung Cancer Complicated By Severe Sensory Autoimmune Neuropathy, Aaron Lobo Md, Nur Rahman Md, Nicholas Blondin Md, Neal Fischbach

Posters

The use of immune checkpoint inhibitors (ICI) in recent years has increasingly emerged as a second-line treatment in the management of extensive-stage small cell lung cancer (ES-SCLC) compared to conventional chemotherapy alone.

The use of combined ICI therapy by inhibiting two distinct pathways in patients with ES-SCLC has been evaluated in clinical trials. The increase incidence of immune related adverse events (Ir-AE) in these trials due to excessive immune system activation or multiple organ disorders has posed serious clinical challenges.

Here we report a dramatic and durable response to combined immune checkpoint blockade without chemotherapy and discuss the relationship between …

Small-Molecule Mitotic Inhibitors As Anticancer Agents: Discovery, Classification, Mechanisms Of Action, And Clinical Trials, Yazmin Salinas, Subhash Chauhan, Debasish Bandyopadhyay

School of Medicine Publications

Despite decades of research, cancer continues to be a disease of great concern to millions of people around the world. It has been responsible for a total of 609,820 deaths in the U.S. alone in 2023. Over the years, many drugs have been developed to remove or reduce the disease’s impact, all with varying mechanisms of action and side effects. One class of these drugs is small-molecule mitotic inhibitors. These drugs inhibit cancer cell mitosis or self-replication, impeding cell proliferation and eventually leading to cell death. In this paper, small-molecule mitotic inhibitors are discussed and classified through their discovery, underlying …

Redefining Cancer Photodynamic Therapy With Gold Nanoparticles, Zoey A. Lockwood, Michael R. Jirousek, James P. Basilion, Clemens Burda

Faculty Scholarship

Despite advancements made in treatment options, cancer continues to be one of the leading causes of death worldwide. Photodynamic therapy (PDT) has gained attention as a minimally invasive and highly selective treatment option for cancer. However, challenges due to the hydrophobicity of photosensitizers and their poor tumor selectivity have limited their use in cancer therapy. Recent developments in nanotechnology, particularly the use of gold nanoparticles (AuNPs), help overcome these challenges. AuNPs provide a stable and biocompatible platform to deliver photosensitizers, improving their solubility, stability, and ability to target tumors while reducing side effects. Functionalized AuNPs take advantage of mechanisms like …

Steroid Receptors And Coregulators: Dissemination Of Sex Differences And Emerging Technologies, Sally Pauss, Evelyn A. Bates, Genesee J. Martinez, Zane T. Bates, Zachary A. Kipp, Cassandra D. Gipson, Terry D. Hinds Jr.

Markey Cancer Center Faculty Publications

Steroid receptors are ligand-induced transcription factors that have broad functions among all living animal species, ranging from control of sex differences, body weight, stress responses, and many others. Their binding to coregulator proteins is regulated by corepressors and coactivators that interchange upon stimulation with a ligand. Coregulator proteins are an imperative and understudied aspect of steroid receptor signaling. Here, we discuss steroid receptor basics from protein domain structures that allow them to interact with coregulators and other proteins, their essential functions as transcription factors, and other elemental protein–protein interactions. We deliberate about the mechanisms that coregulators control in steroid receptor …

Lysyl hydroxylase 2 (LH2) is highly expressed in multiple tumor types and accelerates disease progression by hydroxylating lysine residues on fibrillar collagen telopeptides to generate stable collagen cross links in tumor stroma. Here, we show that a galactosylhydroxylysyl glucosyltransferase (GGT) domain on LH2 modified type-VI collagen (Col6) to promote lung adenocarcinoma (LUAD) growth and metastasis. In tumors generated by LUAD cells lacking LH2 GGT domain activity, stroma was less stiff, and stable types of collagen cross links were reduced. Mass spectrometric analysis of total and glycosylated peptides in parental and GGT-inactive tumor samples identified Col6 chain α3 (Col6a3), a component …

In Kenya, more than 15 % of adolescent girls become pregnant. Forty-three percent of these develop depression. This study investigated adolescent pregnancy in rural Kenya to understand the challenges and context-specific factors that can help adolescents maintain good mental health during pregnancy and the motherhood.

Methods: An exploratory qualitative study was conducted in Kilifi County between October and November 2021. A total of 73 participants consented to participate in the …

Frozen Section Mohs: A Hybrid Technique And One Plastic Surgeon's Experience With 1714 Consecutive Skin Cancer Removals, Michael L. Chang, Steven L. Chang, Fady Gerges, Matthew M. Delancy, Amanda C. Yang, Lawrence D. Chang

Student Papers, Posters & Projects

While US nonmelanoma skin cancer (NMSC) mortality rate has decreased in the past decade, its incidence is rising. Traditional surgical treatments include wide local excision, intraoperative frozen section analysis (IFSA), and Mohs micrographic surgery (MMS). IFSA and MMS are techniques that provide intraoperative analysis allowing the surgeon to confirm margins clear of malignancy and minimize tissue damage, especially in cosmetically sensitive subunits. MMS, with cure rates up to 99%-100%, is considered the gold standard but is limited geographically and financially because of specialized training. We report a hybrid surgical technique that effectively excises cutaneous malignancy but can be utilized by …

Estimating Proximity To Failure Using Repetitions In Reserve In Adults Treated For Cancer, Kylah Elizabeth Jackson

Theses and Dissertations

BACKGROUND: There is a consensus from governing bodies that more evidence is needed in understanding how to properly prescribe, monitor and progress resistance training (RT) in oncology populations. Repetitions in reserve (RIR) has been demonstrated as a quick/easy tool to monitor proximity to failure and interventions using RIR have shown promise in improving muscle strength and mass in older adults and apparently healthy populations. However, the validity of RIR in RT in oncology has yet to be examined. Therefore, the purpose of this study was to assess the accuracy of RIR predications in individuals treated for cancer in a pragmatic …

Faculty, Staff and Student Publications

Background: Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy with neuroendocrine differentiation. Several molecular pathways have been implicated in MCC development and multiple cell-of-origin candidates have been proposed, including neural crest cells, which express acetylcholine receptors (AChRs). The role of nicotinic acetylcholine receptors (nAChRs) in MCC has not been explored. In this study, we investigated if MCC expresses nAChRs and if nAChR expression correlates with patient characteristics.

Methods: The study included 71 MCC cases diagnosed with sufficient tissue available to perform immunohistochemical analysis. The median follow-up was 29.8 months (range, 2.7-234.1). We performed immunohistochemistry using antibodies against the …

The Cgas-Sting1 Pathway As A Mediator Of Innate Immune Response In Cardiovascular Disease, Leila Rouhi, Priyatansh Gurha, Ali J Marian

Faculty, Staff and Student Publications

The innate immune response, a rapid and cell-autonomous response of the cell to the pathogens, recognizes the external as well as the internal pathogens, such as self-DNA, released from the damaged cells. The response activates a set of molecules that induce the expression of proinflammatory cytokines and chemokines and leads to inflammation, fibrosis, and cell death. The innate immune response comprised of DNA-sensing protein cyclic guanosine monophosphate-adenosine monophosphate synthase (CGAS) and its downstream molecules, the stimulator of interferon genes 1 (STING1), TANK-binding kinase 1 (TBK1), interferon regulatory factor 3 (IRF3), and nuclear factor kappa B (NFκB), are activated in several …

In Vivo Antibody Labeling Route And Fluorophore Dictate Labeling Efficiency, Sensitivity, And Longevity, Natalie B Hagan, Charles Inaku, Nikesh Kunder, Tayleur White, Thierry Iraguha, Anna Meyer, Kristen E Pauken, Jason M Schenkel

Faculty, Staff and Student Publications

Leukocytes migrate through the blood and extravasate into organs to surveil the host for infection or cancer. Recently, we demonstrated that intravenous (IV) anti-CD45.2 antibody labeling allowed for precise tracking of leukocyte migration. However, the narrow labeling window can make this approach challenging for tracking rare migration events. Here, we show that altering antibody administration route and fluorophore can significantly extend the antibody active labeling time. We found that while both IV and intraperitoneal (IP) anti-CD45.2 antibody labeled circulating leukocytes after injection, they had different kinetic properties that impacted labeling time and intensity. Quantification of circulating antibody revealed that while …

Effects Of Smoking Behavior On Lung Metastasis In The All Of Us Research Program, Vikram R Shaw, Jinyoung Byun, Younghun Han, Christopher I Amos

Faculty, Staff and Students Publications

Smoking may be associated with an increased risk of lung metastasis in cancers of non-lung origin. We leverage survey and electronic health record data from the diverse All of Us Research Program (AoURP) database to investigate whether smoking and smoking-related behaviors increase the risk of lung metastasis in non-lung primary cancers. The results suggest that cigarette use, measured by four continuous variables, does not increase the risk of lung metastasis in seven common cancer types but demonstrates a small significant effect in a cohort including all types of cancer in the database in both univariable and multivariable analyses. An increased …

Faculty, Staff and Student Publications

The elasticity of soft tissues has been widely considered a characteristic property for differentiation of healthy and lesions and, therefore, motivated the development of several elasticity imaging modalities, for example, ultrasound elastography, magnetic resonance elastography, and optical coherence elastography to directly measure the tissue elasticity. This paper proposes an alternative approach of modeling the elasticity for prior knowledge-based extraction of tissue elastic characteristic features for machine learning (ML) lesion classification using computed tomography (CT) imaging modality. The model describes a dynamic non-rigid (or elastic) soft tissue deformation in differential manifold to mimic the tissues’ elasticity under wave fluctuation in vivo. …
