Paediatric Pseudo Papillary Pancreatic Tumour: A Case Based Review, Mir Ibrahim Sajid, Ayesha Saleem, Muhammad Arshad Jun 2021

Paediatric Pseudo Papillary Pancreatic Tumour: A Case Based Review, Mir Ibrahim Sajid, Ayesha Saleem, Muhammad Arshad

Medical College Documents

Solid pseudopapillary neoplasms are rare and represent approximately 4% of all cystic pancreatic tumours, and predominately affect females. They have an excellent prognosis, however 10-15% of the patients show metastasis at the time of surgery or recurrence of tumour during follow-up after pancreatectomy. Surgical resection is the recommended treatment. We present a rare case of a 15-year-old female, with a pseudopapillary tumour of the pancreas which was diagnosed pre-operatively.

Spermatocytic Tumor Of Testis In A Young Male, Madiha Bilal Qureshi, Nasir Ud Din, Zubair Ahmad, Saira Fatima

Department of Pathology and Laboratory Medicine

Spermatocytic tumor is a rare germ cell tumor not related to germ cell neoplasia in situ, and derived from postpubertal-type germ cells. It was previously called "Spermatocytic Seminoma" due to false belief of its origin from germ cell neoplasia in situ. The tumor usually occurs in an older age group and orchidectomy is curative. We present a case of spermatocytic tumor in a 25-year male who presented with right-sided testicular swelling and right-sided varicocele. Radiology revealed a 9.8 × 9 cm testicular mass and the patient underwent right-sided orchidectomy. Microscopic examination showed classic morphology with three characteristic cell types and …

A Pediatric Case Of Treatment-Related Myelodysplastic Syndrome While On Therapy For Pre-B All, Sara Mcelroy

Research Days

Background: Treatment-related myelodysplastic syndrome (t-MDS) is a known, but rare, late effect of cancer therapy, specifically radiation, alkylating agents or topoisomerase II inhibitors. When secondary to treatment with alkylating agents, t-MDS typically occurs 4 to 7 years after therapy, and common cytogenetics include chromosomes 5 and 7 abnormalities. Treatment in children with t-MDS is typically allogeneic stem cell transplant, but the prognosis remains poor.

Objectives/Goal: To describe a rare case of a pediatric patient who developed t-MDS while receiving treatment for Pre-B Cell Acute Lymphoblastic Leukemia (pre-B ALL) and to outline the treatment regimen that he received.

Methods/Design: Case Report …


Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson May 2021

Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson

Theses & Dissertations

PDAC is a pancreatic epithelial malignancy and demonstrates aggressive progression and bleak patient prognosis. Despite decades of research, the evolution of novel diagnostics and intervention modalities for PDAC is stagnant. This dissertation explores the characteristic aberrant and elevated expression of mucins in PDAC. Beginning with the hypothesis that mucins are associated with disease aggressiveness, analysis of PDAC patient survival in TCGA revealed no associations between single mucin expression and patient survival. This led to the underlying issue of PDAC tumor cellularity since this disease demonstrates variability in the proportion of cancer cells within the tumor. Tumor purity assessed with the …

Introduction

  • Multiple myeloma (MM) is a cancer of plasma cells, which is a white blood cell that normally produces antibodies
  • Treatment in patients younger than 65 years old is typically high dose chemotherapy, usually with bortezomib based regimens or lenalidomide dexamethasone, followed by a stem cell transplant
  • For patients with relapsed myeloma, carfilzomib is usually the treatment of choice
  • Carfilzomib is a highly selective, irreversible proteasome inhibitor that binds to the 20 S proteasome. Several studies have illustrated that carfilzomib has been associated with cardiovascular adverse events (CVAE).
  • Current literature on the role and effect of bortezomib on cardiotoxicity is …


Phyllodes Tumor Containing Invasive Ductal Carcinoma: A Rare Case Description & Review Of Literature, Kathryn Eckert, John Ground, Alyssa Imperatore, Victoria Tiedemann, Linda Szczurek May 2021

Phyllodes Tumor Containing Invasive Ductal Carcinoma: A Rare Case Description & Review Of Literature, Kathryn Eckert, John Ground, Alyssa Imperatore, Victoria Tiedemann, Linda Szczurek

Rowan-Virtua Research Day

Phyllodes tumors are uncommon, often benign, malignancies of the breast and account for approximately 0.5% of all breast malignancies. These tumors were first described in 1838 by Johannes Muller as cystosarcoma phyllodes and were later more aptly renamed phyllodes tumors (as they were neither cystic nor sarcomatous).(1) As a mixed connective tissue and epithelial tumor, these behave similar to benign fibroadenomas, though their growth is much more rapid and they tend to occur in older patients.(2) Hallmarked by their large size at presentation, these tumors average between 4 and 7 cm at the time of diagnosis. The only known risk …

The most common site of prostate metastasis is bone (84%), lymph node (10.6%), liver (10.2%), and thorax (9.1%), with 18.4% to multiple metastatic sites [1]. Prostate metastasis to the brain is rare, with less than 1% documented cases from M.D. Anderson Cancer Center [2]. It is estimated that 1%-6% of prostate cancer metastasis is found in post mortem examination [3]. Parenchymal brain metastasis has a mean survival of 9.2 months after discovery of brain metastasis [4]. Acute neurological symptoms of metastatic prostate cancer are observed …


Multiple Myeloma With Dual Expression Of Kappa And Lambda Light Chains, Monica Patel, Akash Patel, Yvette Wang May 2021

Multiple Myeloma With Dual Expression Of Kappa And Lambda Light Chains, Monica Patel, Akash Patel, Yvette Wang

Rowan-Virtua Research Day

Multiple myeloma (MM) is a malignancy of plasma cells that accounts for approximately 1 to 2 percent of all cancers and about 17% of all hematologic malignancies.

Plasma cells normally produce antibodies and provide a defense mechanism for the body to fight infections.

Antibodies typically consist of two heavy chains (IgG, IgA, IgM, IgD and IgE) and two light chains (kappa and lambda).

Most cases of MM have malignant plasma cells producing monoclonal (M) proteins, most common being IgG about 52% of the time (1).

Only about 2% of these myeloma cases were also found to secrete more than one …


Keeping Primary Care Providers Informed About Detecting Skin Cancer In Young Adults, Riley J. Spears May 2021

Keeping Primary Care Providers Informed About Detecting Skin Cancer In Young Adults, Riley J. Spears

Evidence-Based Practice Project Reports

Skin cancer is a common, life-threatening disease that affects anyone, regardless of age or skin color (American Cancer Society [ACS], 2020). The incidence of melanoma is on the rise for young adults, with an estimated 2,400 new cases for individuals aged 15 to 29 (ACS, 2020). Although skin cancer is highly preventable, clinical guidelines are inconsistent regarding skin cancer screening. The purpose of this evidence-based practice (EBP) project was to determine if the implementation of the INternet curriculum FOR Melanoma Early Detection (INFORMED) program would improve primary care providers’ (PCPs’) confidence about skin cancer and the number of completed and …

Novel Mouse Model For Analysis Of Macrophage Function In Neuroblastoma, Gabrielle L. Brumfield, Shelby M. Knoche, Alaina C. Larson, Brittany Poelaert, Benjamin T. Goetz, Poomy Pandey, Don W. Coulter, Joyce C. Solheim

Child Health Research Institute Pediatric Research Forum

Background: Neuroblastoma is the third most common childhood cancer and accounts for 12% of cancer-associated deaths in children under the age of 15. Patients with high risk neuroblastoma have a poor 5-year survival rate of less than 50%. Neuroblastoma tumors treated with the histone deacetylase inhibitor (HDACi) vorinostat have increased infiltration of macrophages with upregulated immune cell-surface receptors. Neuroblastoma cells release VEGF and M-CSF, which may alter intratumoral macrophage populations. VEGF has also been implicated in alteration of amyloid precursor protein family processing. Our lab demonstrated that amyloid precursor protein 2 (APLP2), a member of the amyloid precursor protein …

Harnessing The Power Of Trained Immunity In The Setting Of Pancreatic Cancer: A Novel Mechanism Of Immune Trafficking And Tumor Control., Anne Elena Geller May 2021

Harnessing The Power Of Trained Immunity In The Setting Of Pancreatic Cancer: A Novel Mechanism Of Immune Trafficking And Tumor Control., Anne Elena Geller

Electronic Theses and Dissertations

Despite the success of immunotherapy in many types of cancer, pancreatic adenocarcinoma (PDAC) has yet to benefit. Innate immune cells are critical to antitumor immunosurveillance and recent studies have revealed that these populations possess a form of memory, termed trained innate immunity, which occurs through transcriptomic, epigenetic, and metabolic reprograming. Though trained innate immunity has mostly been investigated in the context of infection, the induction of trained innate immunity could also protect against tumors, and specifically pancreatic tumors. Here, we demonstrate that yeast-derived particulate β-glucan, a known inducer of trained immunity, traffics to the pancreas following IP administration. This causes …


Breast Cancer Risk For Female Relatives Of Male Breast Cancer Patients With Negative Brca1/2 Testing, Emily Martin May 2021

Breast Cancer Risk For Female Relatives Of Male Breast Cancer Patients With Negative Brca1/2 Testing, Emily Martin

Dissertations and Theses (Open Access)

Risk models exist to estimate a female’s lifetime risk of breast cancer in the absence of a hereditary predisposition to cancer, namely Hereditary Breast and Ovarian Cancer syndrome. These risk models consider various factors such as reproductive history and family history, but few models take a family history of male breast cancer into account. This study aims to evaluate if prevalence of breast cancer among female relatives is higher when there is a family history of male breast cancer in the context of uninformative BRCA1 and BRCA2 testing. This information may aid in the process of risk assessments for patients …

Proteomic Investigation Of Glyceraldehyde-Derived Intracellular Ages And Their Potential Influence On Pancreatic Ductal Cells, Lakmini Senavirathna, Cheng Ma, Ru Chen, Sheng Pan

Faculty, Staff and Students Publications

Glyceraldehyde-derived advanced glycation end products (AGEs) play an important role in the pathogenesis of many diseases including cancer. Accumulation of intracellular AGEs could stimulate cancer induction and facilitate cancer progression. We evaluated the toxic effect of glyceraldehyde-derived intracellular AGEs on normal and malignant pancreatic ductal cells by assessing the cell viability, toxicity, and oxidative stress, followed by proteomic analysis. Our functional studies showed that pancreatic cancer cells (PANC-1 and MIA PaCa-2) were more resistant to glyceraldehyde treatment compared to normal pancreatic ductal epithelial cells (HPDE), while cytotoxicity effects were observed in all cell types. Furthermore, using 13C isotopic labeled glyceraldehyde, …

Structure, Function And Inhibition Of Critical Protein-Protein Interactions Involving Mixed Lineage Leukemia 1 And Its Fusion Oncoproteins, Xin Li, Yongcheng Song Apr 2021

Structure, Function And Inhibition Of Critical Protein-Protein Interactions Involving Mixed Lineage Leukemia 1 And Its Fusion Oncoproteins, Xin Li, Yongcheng Song

Faculty, Staff and Students Publications

Mixed lineage leukemia 1 (MLL1, also known as MLL or KMT2A) is an important transcription factor and histone-H3 lysine-4 (H3K4) methyltransferase. It is a master regulator for transcription of important genes (e.g., Hox genes) for embryonic development and hematopoiesis. However, it is largely dispensable in matured cells. Dysregulation of MLL1 leads to overexpression of certain Hox genes and eventually leukemia initiation. Chromosome translocations involving MLL1 cause ~ 75% of acute leukemia in infants and 5-10% in children and adults with a poor prognosis. Targeted therapeutics against oncogenic fusion MLL1 (onco-MLL1) are therefore needed. Onco-MLL1 consists of the N-terminal DNA-interacting domains …


Predicting Tumor Response To Radiotherapy Based On Estimation Of Non-Treatment Parameters, Yutian Huang, Allison L. Lewis Apr 2021

Predicting Tumor Response To Radiotherapy Based On Estimation Of Non-Treatment Parameters, Yutian Huang, Allison L. Lewis

Spora: A Journal of Biomathematics

Though clinicians can now collect detailed information about a variety of tumor characteristics as a tumor evolves, it remains difficult to predict the efficacy of a given treatment prior to administration. Additionally, the process of data collection may be invasive and expensive. Thus, the creation of a framework for predicting patient response to treatment using only information collected prior to the start of treatment could be invaluable. In this study, we employ ordinary differential equation models for tumor growth and utilize synthetic data from a cellular automaton model for calibration. We investigate which parameters have the most influence upon treatment …


The Heme-Regulated Inhibitor Pathway Modulates Susceptibility Of Poor Prognosis B-Lineage Acute Leukemia To Bh3-Mimetics, Kaitlyn Hill Smith Apr 2021

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 …

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: High-resolution microendoscopy (HRME) is an optical biopsy technology that provides subcellular imaging of esophageal mucosa but requires expert interpretation of these histopathology-like images. We compared endoscopists with an automated software algorithm for detection of esophageal squamous cell neoplasia (ESCN) and evaluated the endoscopists' accuracy with and without input from the software algorithm.

METHODS: Thirteen endoscopists (6 experts, 7 novices) were trained and tested on 218 post-hoc HRME images from 130 consecutive patients undergoing ESCN screening/surveillance. The automated software algorithm interpreted all images as neoplastic (high-grade dysplasia, ESCN) or non-neoplastic. All endoscopists provided their interpretation (neoplastic or non-neoplastic) …
