Fatal Autoimmune Storm After A Single Cycle Of Anti-Pd-1 Therapy: A Case Of Lethal Toxicity But Pathological Complete Response In Metastatic Lung Adenocarcinoma, Jesús Fuentes-Antras, Paloma Peinado, Kissy Guevara-Hoyer, Cristina Díaz Del Arco, Silvia Sanchez-Ramon, Carlos Aguado

Hematology/Oncology and Stem Cell Therapy

As immunotherapy agents are incorporated into the routine oncological practice, the number of patients at the risk of immune-related adverse events has increased dramatically. However, the prompt identification and effective management of severe autoimmune complications remain a challenge. We report the case of a patient with metastatic lung adenocarcinoma who experienced a fatal autoimmune storm 3 weeks after the first dose of anti-programmed death receptor-1 (PD-1) agent pembrolizumab, which included thyroiditis, hepatitis, myositis, myocarditis, pneumonitis, and myasthenia gravis. Aggressive autoimmunity was supported by extensive T-cell and macrophage tissue infiltrates and autoantibody positivity. Remarkably, no residual tumor was found at autopsy ...

Ofatumumab For Post-Transplant Lymphoproliferative Disorder, Madhav Seshadri, Genevieve M. Crane, Usama Gergis

Hematology/Oncology and Stem Cell Therapy

Posttransplant lymphoproliferative disorder (PTLD) includes a range of abnormal lymphoid proliferation following solid organ or allogeneic hematopoietic stem cell transplantation (HSCT), often associated with EpsteineBarr virus (EBV) infection. Treatment generally incudes rituximab, a chimeric monoclonal antibody directed against CD20. Here we present a 56-year-old woman with EBV-associated PTLD following allogeneic HSCT who was intolerant of rituximab. The patient was instead treated with ofatumumab, a fully human monoclonal antibody directed against CD20, with significant response in EBV viral load and lymphadenopathy. Ofatumumab could represent an important treatment option for patients unable to tolerate rituximab.

Hematology/Oncology and Stem Cell Therapy

The management of immune thrombocytopenic purpura (ITP) involves several lines of therapy such as corticosteroids and intravenous immunoglobulin. With the emergence of novel therapies such as thrombopoietin receptor agonists (TPO-RAs), there has been a shift in treatment modalities. Eltrombopag and romiplostim have proven to be effective in the management of ITP through clinical studies, but their safety in pregnancy remains uncertain. The purpose of the study is to review the literature to evaluate the safety of TPO-RAs in pregnant women. Ten case reports and a cohort study pertaining to the use of TPO-RAs in pregnancy were obtained. According to the ...

Hematology/Oncology and Stem Cell Therapy

Glanzmann’s thrombasthenia (GT) is an autosomal recessive congenital bleeding disorder of platelet aggregation. Mutations in ITGA2B and ITGB3 genes result in quantitative and/or qualitative abnormalities of the glycoprotein receptor complex IIb/IIIa (integrin aIIbb3), which in turn impairs platelet aggregation and lead to GT. In this study, whole genome single nucleotide polymorphism (SNP) genotyping as well as whole exome sequencing was performed in a large family segregating GT. Analysis of the genotypes localized the disease region to chromosome 17q21.2eq21.3. Filtration of whole exome data and candidate variants prioritization identified a pathogenic variant in the ITGB3 gene ...


Recurrence Score Testing Does Not Appear To Benefit Patients With Grade 1, Progesterone Receptor Positive Breast Cancers: An Opportunity To Eliminate Over-Treatment And Decrease Testing Costs, Udai S. Sibia, Thomas J. Sanders, Charles Mylander, Martin Rosman, Carol Tweed, Lorraine Tafra, Rubie S. Jackson 2022 The Rebecca Fortney Breast Center, Anne Arundel Medical Center, Annapolis, MD, USA

Recurrence Score Testing Does Not Appear To Benefit Patients With Grade 1, Progesterone Receptor Positive Breast Cancers: An Opportunity To Eliminate Over-Treatment And Decrease Testing Costs, Udai S. Sibia, Thomas J. Sanders, Charles Mylander, Martin Rosman, Carol Tweed, Lorraine Tafra, Rubie S. Jackson

Hematology/Oncology and Stem Cell Therapy

Background: We previously described a risk prediction model (Anne Arundel Medical Center [AAMC] model) based on pathology which may eliminate the need for recurrence score (RS) testing in select early-stage breast cancers. There is a concern that patients in discordant risk prediction groups (AAMC vs. RS) may be overtreated or undertreated if RS testing were omitted. Methods: We queried the Surveillance, Epidemiology, and End Results (SEER) database for all breast cancer patients between 2004 and 2015. AAMC low-risk was defined as Grade 1 and progesterone receptor-positive (PR þ ) tumors, while AAMC high-risk was defined as Grade 3 or estrogen-negative tumors ...

Using The Appropriate Formula For Qt Measurement Can Save Lives, Taher Taher Al-Tweigeri Taher

Hematology/Oncology and Stem Cell Therapy

CDK 4/6 inhibitors, in combination with endocrine therapy, are the standard of care for patients with endocrine sensitive advanced breast cancer. This class of drug, however, is associated with QT prolongation, which serves as a surrogate marker for Torsades de Pointes (TdP), a cause of life-threatening ventricular arrhythmias and sudden cardiac death. The ICH E14 guidance document uses the Bazett formula for reporting of cardio-dynamic and safety ECG data in clinical trials. While there is substantial familiarity with the Bazett (QTcB) formula (QT/(RR) 1/2), the Fridericia (QTcF) formula (QT/(RR) 1/3 ) is preferred in the cancer ...

Efficacy Of Allogeneic Hematopoietic Cell Transplantation In Patients With Chronic Phase Cml Resistant Or Intolerant To Tyrosine Kinase Inhibitors, Farah Yassine, Tea Reljic, Muhamad Alhaj Moustafa, Madiha Iqbal, Hemant S. Murthy, Ambuj Kumar, Mohamed A. Kharfan-Dabaja

Hematology/Oncology and Stem Cell Therapy

Approximately 15-20% of chronic myeloid leukemia (CML) patients fail tyrosine kinase inhibitor (TKI) therapy secondary to resistance or intolerance. In the pre-TKI era, front-line allogeneic hematopoietic cell transplantation (alloHCT) represented the standard approach for patients with chronic phase-CML (CP-CML) who were deemed fit to tolerate the procedure and had a human leukocyte antigen compatible donor available. Currently, CP-CML patients are eligible for allo-HCT only if they fail more than one TKI and/or are intolerant to the drug. We performed a systematic review/meta-analysis of the available literature to assess the evidence regarding allo-HCT efficacy in CP-CML patients. Data from ...

Background: Neoadjuvant chemotherapy (NACT) is an increasingly used approach for treatment of breast cancer. The pathological complete response (pCR) is considered a good predictor of disease-specific survival. This study investigated whether circulating exosomal microRNAs could predict pCR in breast cancer patients treated with NACT. Method: Plasma samples of 20 breast cancer patients treated with NACT were collected prior to and after the first cycle. RNA sequencing was used to determine microRNA profiling. The Cancer Genome Atlas (TCGA) was used to explore the expression patterns and survivability of the candidate miRNAs, and their potential targets based on the expression levels and ...

Interferon-gamma (IFN-γ) is shown to stimulate melanoma development and progression. However, the underlying mechanism has not been completely defined. Our study aimed to determine the role of neuronal nitric oxide synthase (nNOS)-mediated signaling in IFN-γ-stimulated melanoma progression and the anti-melanoma effects of novel nNOS inhibitors. Our study shows that IFN-γ markedly induced the expression levels of nNOS in melanoma cells associated with increased intracellular nitric oxide (NO) levels. Co-treatment with novel nNOS inhibitors effectively alleviated IFN-γ-activated STAT1/3. Further, reverse phase protein array (RPPA) analysis demonstrated that IFN-γ induced the expression of HIF1α, c-Myc, and programmed death-ligand 1 (PD-L1 ...

Altered fatty acid metabolism continues to be an attractive target for therapeutic intervention in cancer. We previously found that colorectal cancer (CRC) cells with a higher metastatic potential express a higher level of fatty acid translocase (CD36). However, the role of CD36 in CRC metastasis has not been studied. Here, we demonstrate that high expression of CD36 promotes invasion of CRC cells. Consistently, CD36 promoted lung metastasis in the tail vein model and GI metastasis in the cecum injection model. RNA-Seq analysis of CRC cells with altered expression of CD36 revealed an association between high expression of CD36 and upregulation ...


The Role Of Irf-1 In Spontaneous Mouse Glioma, Aakash B. Vaidya 2022 Virginia Commonwealth University

The Role Of Irf-1 In Spontaneous Mouse Glioma, Aakash B. Vaidya

Theses and Dissertations

Glioblastoma Multiforme has been shown to be one of the deadliest primary brain cancers. One of the reasons why GBM is so deadly, is a unique immunosuppressive tumor microenvironment that promotes GBM growth and progression. Both astrocyte and microglia have been implicated in immunosuppression. In this study, we explored the role of Interferon Regulatory Factor 1 (IRF-1) in astrocytes and glioma cells on the growth of spontaneous glioma tumors. IRF-1 is regulated by the JAK/STAT pathway and induces expression of Programmed death ligand 1 (PD-L1). PD-L1 downregulates immune responses to glioma. We found that IRF-1 had no effect on ...


Novel Mechanism Of Endogenous Pancreatic Cancer Cell Expression Of Immune Checkpoint Programmed Cell-Death 1 Protein (Pd-1) Inducing Epithelial-To-Mesenchymal Transition (Emt) Through The Met Pathway And Promoting Cancer Progression In An Immune-Independent Process, Megan M.

Novel Mechanism Of Endogenous Pancreatic Cancer Cell Expression Of Immune Checkpoint Programmed Cell-Death 1 Protein (Pd-1) Inducing Epithelial-To-Mesenchymal Transition (Emt) Through The Met Pathway And Promoting Cancer Progression In An Immune-Independent Process, Megan M. Harper

Theses and Dissertations--Clinical and Translational Science

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers with few treatment options, necessitating an urgent need for novel therapeutics. Immuno-oncologic (IO) therapies have revolutionized anti-cancer regimens in the past decade but typically involve reactivation of adaptive immune responses. In particular, immune checkpoint PD-1 is traditionally expressed only on immune cells while PD-L1 (PD-1 ligand) is overexpressed on cancer cells. When tumor-endogenous PD-L1 binds the PD-1 receptor on T-cells, the immune cells undergo anergy resulting in self-tolerance and cancer cell immune evasion. However, contrary to standard dogma, we previously demonstrated tumor-endogenous PD-1 expression in PDAC. Our data indicated that ...

A Novel Drug To Induce Apoptosis In Advanced Prostate Cancer Cells, Parshva A. Sanghvi

Honors Undergraduate Theses

Prostate cancer is one of the leading causes of death for men in America as approximately 1 in 41 men will have prostate cancer. In this research, we focus on enzalutamide-resistant prostate cancer cells as cell resistance to enzalutamide is a prevalent obstacle in treating prostate cancer. We tested a novel compound library at different doses and observed each compound's efficacy in inducing apoptosis in enzalutamide-resistant cells. Furthermore, we analyzed the mechanism by which apoptosis was induced in compounds that showed a high efficacy at lower doses. Overall, we found that Darapladib shows promising results in treating cells that ...

Exosomes are nano-vesicles (NVs) secreted by cells and take part in cell-cell communications. Lately, these exosomes were proved to have dual faces in cancer. Actually, they can contribute to carcinogenesis through epithelial-mesenchymal transition (EMT), angiogenesis, metastasis and tumor microenvironment (TME) of various cancers, including colorectal cancer (CRC). On the other hand, they can be potential targets for cancer treatment. CRC is one of the most frequent tumors worldwide, with incidence rates rising in the recent decades. In its early stage, CRC is asymptomatic with poor treatment outcomes. Therefore, finding a non-invasive, early diagnostic biomarker tool and/or suitable defender to ...


Targeting The Bcl6 Transcription Factor In Ovarian Cancer, Harrison H. Parent 2022 University of New Hampshire, Durham

Targeting The Bcl6 Transcription Factor In Ovarian Cancer, Harrison H. Parent

Honors Theses and Capstones

Ovarian cancer is one of the most common reproductive malignancies for women in the United States, as well as one of the deadliest. Many deaths attributed to ovarian cancer, as well as cancer generally, are due to metastasis of the original tumor to different tissues throughout the body. The BCL6 transcription factor has been identified to play a key role in the metastasis of these tumors, as well as the invasion of these cancer cells through mesothelial cell layers, which contributes to ovarian cancer’s unique metastatic behavior. In an attempt to target these metastases and prevent mesothelial penetration, drugs ...
