Tumor Surveillance Using Liquid Biome In Pediatric High Grade Gliomas, Erin Bonner, Eshini Panditharatna, Madhuri Kambhampati, Stefaan Van Gool, Wilfried Stuecker, Roger J. Packer, Javad Nazarian

GW Research Days 2016 - Present

Immunotherapy is currently being used to treat pediatric brain cancer, though its efficacy in treating patients with diffuse intrinsic pontine glioma (DIPG), the deadliest pediatric brain tumor, has not been evaluated. MRI is the gold standard for monitoring tumor response to therapy, but is limited by pseudoresponse and psuedoprogression: post-treatment, immune cells infiltrate the primary tumor causing transient tumor enlargement, which falsely resembles tumor progression on MRI. Thus, it is critical to develop more accurate approaches to monitor tumor response to immunotherapy. Here, we use a liquid biopsy platform we have already established to monitor tumor response to therapy, to ...

Communicating Effectively In Pediatric Cancer Care: Translating Evidence Into Practice., Lindsay J Blazin, Cherilyn Cecchini, Catherine Habashy, Erica C Kaye, Justin N Baker

Pediatrics Faculty Publications

Effective communication is essential to the practice of pediatric oncology. Clear and empathic delivery of diagnostic and prognostic information positively impacts the ways in which patients and families cope. Honest, compassionate discussions regarding goals of care and hopes for patients approaching end of life can provide healing when other therapies have failed. Effective communication and the positive relationships it fosters also can provide comfort to families grieving the loss of a child. A robust body of evidence demonstrates the benefits of optimal communication for patients, families, and healthcare providers. This review aims to identify key communication skills that healthcare providers ...

Tumorigenic Proteins Upregulated In The Mycn-Amplified Imr-32 Human Neuroblastoma Cells Promote Proliferation And Migration., Hayat Zaatiti, Jad Abdallah, Zeina Nasr, George Khazen, Anthony Sandler, Tamara J Abou-Antoun

Surgery Faculty Publications

Childhood neuroblastoma is one of the most common types of extra-cranial cancer affecting children with a clinical spectrum ranging from spontaneous regression to malignant and fatal progression. In order to improve the clinical outcomes of children with high-risk neuroblastoma, it is crucial to understand the tumorigenic mechanisms that govern its malignant behaviors. MYCN proto-oncogene, bHLH transcription factor (MYCN) amplification has been implicated in the malignant, treatment-evasive nature of aggressive, high-risk neuroblastoma. In this study, we used a SILAC approach to compare the proteomic signatures of MYCN-amplified IMR-32 and non-MYCN-amplified SK-N-SH human neuroblastoma cells. Tumorigenic proteins, including fatty-acid binding protein 5 ...

Humanized Mice In Studying Efficacy And Mechanisms Of Pd-1-Targeted Cancer Immunotherapy, Minan Wang, Michael A. Brehm, Dale L. Greiner

Open Access Articles

Establishment of an in vivo small animal model of human tumor and human immune system interaction would enable preclinical investigations into the mechanisms underlying cancer immunotherapy. To this end, nonobese diabetic (NOD).Cg- Prkdc(scid)IL2rg(tm1Wjl)/Sz (null; NSG) mice were transplanted with human (h)CD34(+) hematopoietic progenitor and stem cells, which leads to the development of human hematopoietic and immune systems [humanized NSG (HuNSG)]. HuNSG mice received human leukocyte antigen partially matched tumor implants from patient-derived xenografts [PDX; non-small cell lung cancer (NSCLC), sarcoma, bladder cancer, and triple-negative breast cancer (TNBC)] or from a TNBC cell line-derived xenograft ...

Kallikrein-Related Peptidases Are Dysregulated In Pleomorphic Adenoma, Matthew D. Morrison

Electronic Thesis and Dissertation Repository

Objectives: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. Kallikrein-related peptidases (KLKs) have been identified as biomarkers in many human tumors and may influence tumor behavior. We investigated KLK1-15 messenger ribonucleic acid (mRNA) and proteins in PA specimens to determine a KLK expression profile for this tumor.

Methods: Fresh frozen PA tissue specimens (n = 26) and matched controls were subjected to RT-qPCR to detect KLK1-15 mRNA. Expression of KLK1, KLK12, KLK13 and KLK8 proteins were then evaluated via immunostaining techniques. Statistical analyses were performed with the level of significance set at P < .05.

Results: We observed downregulation of ...

Metastatic Extramammary Paget's Disease: Pathogenesis And Novel Therapeutic Approach, Keitaro Fukuda, Takeru Funakoshi

Open Access Articles

Extramammary Paget's disease (EMPD) is a rare, slow-growing, cutaneous adenocarcinoma that usually originates in the anogenital area and axillae outside the mammary glands. EMPD mostly progresses slowly and is often diagnosed as carcinoma in situ; however, upon becoming invasive, it promptly and frequently metastasizes to regional lymph nodes, leading to subsequent distant metastasis. To date, several chemotherapy regimens have been used to treat metastatic EMPD; however, they present limited effect and patients with distant metastasis exhibit a poor prognosis. Recently, basic and translational investigative research has elucidated factors and molecular mechanisms underlying the promotion of metastasis, which can lead ...

Positioning Of Patients For Pelvic Radiation: Variability Across Treatment, Mashhood Ahmad Bodla, Alexander Lukez, Lauren O'Loughlin, Jennifer Baima, Janaki Moni

Orthopedics and Physical Rehabilitation Publications and Presentations

Objectives: We aimed to determine the variability in position of the pelvis for patients while receiving daily radiation treatments for pelvic malignancies.

Design: Therapeutic radiation targets lymph nodes that lie along the curvature of the sacrum. Any change in pelvic tilt could inadvertently move these targets in or out of the radiation field. This variability has clinical significance both to target cancerous lymph nodes and avoid healthy sacrum.

To better understand this variability, we observed trends in the change in the sacral slope. This measurement was chosen because it is an objective radiographic finding, there is no significant difference between ...

Oncogenomic studies indicate that copy number variation (CNV) alters genes involved in tumor progression; however, identification of specific driver genes affected by CNV has been difficult, as these rearrangements are often contained in large chromosomal intervals among several bystander genes. Here, we addressed this problem and identified a CNV-targeted oncogene by performing comparative oncogenomics of human and zebrafish melanomas. We determined that the gene encoding growth differentiation factor 6 (GDF6), which is the ligand for the BMP family, is recurrently amplified and transcriptionally upregulated in melanoma. GDF6-induced BMP signaling maintained a trunk neural crest gene signature in melanomas. Additionally, GDF6 ...

Real-World Usage And Clinical Outcomes Of Alectinib Among Post-Crizotinib Progression Anaplastic Lymphoma Kinase Positive Non-Small-Cell Lung Cancer Patients In The Usa, Marco D. Dibonaventura, William Wong, Bijal M. Shah-Manek, Mathias Schulz

College of Pharmacy (TUC) Publications and Research

Background: Alectinib is an approved treatment for anaplastic lymphoma kinase (ALK)-positive patients with advanced non-small-cell lung cancer. Despite positive supporting clinical data, there is a lack of real-world information on the usage and patient outcomes of those treated with alectinib post-crizotinib progression.

Methods: Participating oncologists (N=95) in the USA were recruited from an online physician panel to participate in a retrospective patient chart review. Physicians randomly selected eligible patients (ie, patients who progressed on crizotinib as their first ALK inhibitor and were treated with alectinib as their second ALK inhibitor), collected demographics and clinical history from their medical ...

The Role Of Tgf-Β/Smad4 Signaling In Cancer, M Zhao, Lopa Mishra, C Deng

Surgery Faculty Publications

Transforming growth factor β (TGF-β) signaling pathway plays important roles in many biological processes, including cell growth, differentiation, apoptosis, migration, as well as cancer initiation and progression. SMAD4, which serves as the central mediator of TGF-β signaling, is specifically inactivated in over half of pancreatic duct adenocarcinoma, and varying degrees in many other types of cancers. In the past two decades, multiple studies have revealed that SMAD4 loss on its own does not initiate tumor formation, but can promote tumor progression initiated by other genes, such as KRAS activation in pancreatic duct adenocarcinoma and APC inactivation in colorectal cancer. In ...

Pre- And Post-Diagnosis Physical Activity, Television Viewing, And Mortality Among Hematologic Cancer Survivors., Daniela Schmid, Gundula Behrens, Hannah Arem, Christina Hart, Wolfgang Herr, Carmen Jochem, Charles E Matthews, Michael F Leitzmann

Epidemiology and Biostatistics Faculty Publications

PURPOSE: The associations of physical activity and television (TV) viewing with mortality risk among individuals with hematologic malignancies remain unclear.

METHODS: We examined the relations of physical activity and TV viewing time before and after diagnosis with mortality among 5182 U.S. adults aged 50-71 years from the NIH-AARP Diet and Health Study cohort who survived a first primary hematologic cancer between 1995-1996 and 2011.

RESULTS: For the pre- and post-diagnosis analyses, we confirmed 2606 and 613 deaths respectively. In multivariable-adjusted Cox proportional hazard regression models, comparing high (≥4 hrs/wk) versus low (/wk) activity levels, pre-diagnosis physical activity was ...

Mantle Cell Lymphoma In The Thyroid: A Rare Presentation, Uzma Mohammad Siddiqui, Sarika N. Rao, Pallavi K. Galera, Nahida Islam, Mira S. Torres

Open Access Articles

Background: While 2% of all extranodal Non-Hodgkin Lymphomas present in the thyroid, there exists insufficient data to describe the incidence of mantle cell lymphoma in the thyroid. A case series of 1400 patients revealed that < 1% of thyroid lymphomas may be MCL; hence better understanding of the disease course is essential.

Patient Findings: A 65-year-old female was referred for a multinodular goiter. Multiple fine needle aspirations from the dominant right nodule were consistent with Hashimoto's thyroiditis and flow cytometry was negative. Due to progressing dysphagia, she underwent total thyroidectomy.

Summary: Pathology revealed MCL with mantle zone growth pattern in the right thyroid. Flow cytometry showed monoclonal B cells comprising 9% of total cells. The Ki-67 ...
