Detection Of Progression Or Regression Of Breast Cancer By Circulating Tumor Dna (Ctdna), Ujjwal Karki, Bipin Ghimire, Emma Herrman, Siddhartha Yadav, Mohammad Muhsin Chisti

Conference Presentation Abstracts

Circulating tumor DNA (ctDNA) are short DNA sequences shed by tumor cells into the systemic circulation. Studies have shown potential utility of the test to predict relapse or recurrence following treatment in solid tumors, but sensitivity and specificity have varied widely, ranging from 19-100% and 80-100% respectively, in breast cancer specifically. Moreover, literature describing the utility of monitoring dynamic changes in ctDNA trends is limited. We aim to evaluate the correlation between ctDNA test, both single test as well as dynamic trends in value over time, with imaging findings.

Conference Presentation Abstracts

Introduction

Non-alcoholic fatty liver disease (NAFLD) is one of the leading causes of chronic liver diseases. NAFLD spectrum begins from simple steatosis to non-alcoholic steatohepatitis (NASH), progressive fibrosis, cirrhosis, and even hepatocellular carcinoma. Although most NAFLD patients are overweight and obese, 30% are lean. We analyzed lean and non-lean NAFLD patients’ liver biopsies for cytokeratin 8/18 immunohistochemical staining differences.

Aims & Methods

Thirty biopsy-proven NAFLD patients (15 patients with BMI ≤ 25 kg/m2, 15 patients with BMI > 25 kg/m2) were included in the study. Demographic, biochemical, and histologic features of the patients were recorded. Biopsy specimens from our archive were …

Bet Protein Complexes With Ets1 And Mediates The Senescence-Associated Secretory And Apoptotic Resistant Phenotypes Of Senescent Cholangiocytes, Jeong-Han Kang, Patrick Splinter, Christy Trussoni, Nicholas E. Pirius, Maria Eugenia Guicciardi, Anuradha Krishnan, Nazli Begum Ozturk, Gregory J. Gores, Nicholas F. Larusso, Steven P. O'Hara

Conference Presentation Abstracts

Background: We reported that cholangiocyte senescence is a pathogenic feature of Primary Sclerosing Cholangitis (PSC) and is regulated by the transcription factor, ETS1. We also showed that Histone 3 Lysine 27 is acetylated at senescence-associated loci. The bromodomain and extra-terminal domain (BET) proteins are epigenetic readers that bind acetylated histones, recruit transcription factors, and drive gene expression. Thus, we tested the hypothesis that BET proteins interact with ETS1 to drive gene expression and promote cholangiocyte senescence. Methods: We performed immunofluorescence to assess cholangiocyte expression of two BET proteins, BRD2 and BRD4, in tissue from PSC patients and PSC mouse models …

Conference Presentation Abstracts

BACKGROUND: The SAR-CoV-2 pandemic continues to negatively impact the healthcare system globally with over 800,000 deaths in the United States and millions more worldwide. The cases are rising despite availability of vaccines. For most immunocompetent patients these vaccines will generate a humoral response and also a memory T-cell response. Few if any studies have reported data that measure anti-spike IgG titers and also correlate those titers with clinical outcomes in the instance of breakthrough infection.

METHODS: We conducted a pilot prospective observational clinical study enrolling 30 immunocompetent patients who were admitted with a positive SARS-CoV-2 PCR. Leftover blood from admission …

A Systematic Review And Meta-Analysis Of Diagnostic Accuracy Of Whole-Body 18f-Fdg Pet And 18f-Fdg Pet/Ct In Detecting Occult Malignancy In Patients With Idiopathic Inflammatory Myopathy, A Ali, R Alkilany, J Asif, B Basida, Z Al-Sagri, N Mahabadi, H Sarakbi

Conference Presentation Abstracts

Background Idiopathic inflammatory myopathies (IIMs) are chronic, systemic autoimmune diseases that can cause muscle inflammation, weakness, and skin manifestations. Several studies have confirmed the association between IIMs and malignancy in adult population with varied frequency (4-42%), highest in patients with dermatomyositis. Detecting occult malignancy is a diagnostic challenge involving cost- and time-consuming methods. The (18)F] fluorodeoxyglucose positron emission tomography ([(18)F] FDG-PET) role in this context has been studied in multiple studies.

Objectives The purpose of this study is to assess the diagnostic performance of whole-body 18F-FDG PET or 18F-FDG PET/CT for detection of occult malignancy in patients with IIMs.

Small Cell Carcinoma Of The Anal Canal: A Rare Entity, Shailesh Niroula, Ujjwal Jung Karki, Bipin Ghimire, Shrinjaya Thapa

Conference Presentation Abstracts

Neoplasm of anal canal are <5% of the malignancy of gastrointestinal tract. Majority of the cancers are squamous cell and adenocarcinoma. Primary small cell carcinoma of the anal canal is a very rare diagnosis with only handful of cases reported in literature. 66-year-old female with multiple co-morbidities presented with rectal pain. She had initially noticed hemorrhoids six months prior to presentation. CT abdomen and pelvis showed bilateral inguinal lymphadenopathy and diverticulosis. Patient then had colonoscopy which showed mass in the anal canal, initial biopsy showed squamous cell carcinoma with basaloid features. Lymph node biopsy was also positive for metastatic cancer likely anal in origin. PET scan showed metastatic lesion in the lumbar vertebra. Review of slides was done before starting chemotherapy as component of small cell carcinoma was also seen. Due to diagnostic dilemma, patient was initially started on Carboplatin and Paclitaxel first cycle as it is effective against both squamous and small cell carcinoma. Repeat evaluation of the slides confirmed small cell cancer as the diagnosis and chemotherapy was changed to carboplatin and etoposide. Patient received 3 cycles of the carboplatin and etoposide after which atezolizumab was added. She received total of 6 cycles of the chemotherapy. Repeat PET scan showed partial favorable response. Due to rarity of the disease, there was significant delay in diagnosis of the cancer. Diagnosis of small cell carcinoma in the anal canal relies on neuroendocrine differentiation. There is no formal evidence-based recommendation regarding treatment. They are considered equivalent to pulmonary small cell carcinoma and treated in similar manner.

Conference Presentation Abstracts

With an estimated five-year survival of less than 40 percent, angiosarcomas are rare and often misdiagnosed fataltumors originating from blood or lymphatic vessels with a predilection for the head and neck. They account for 1percent of all soft tissue sarcomas and are often mistaken for benign mimickers leading to the late-stage diagnosiswhen the body is already riddled with metastatic disease with the lung being the most common site of metastases.This case illustrates the myriad of pulmonary complications associated with this uncommon but fatal vasoformativemalignancy. The patient is a 73-year-old male diagnosed with angiosarcoma of the right scalp status post excision,reconstruction, …

Clinical Pathways Leading To Antibiotic Initiation In Patients With Suspected Infection And Their Association With Delays And Mortality, X Han, C Lopez-Espina, P A. Verhoef, A Spicer, A Bhargava, L Schmalz, Matthew Sims, Alexandra Halalau, Nicholas Maddens, Aimee Espinosa

Conference Presentation Abstracts

Rationale: Delayed antibiotic therapy is associated with increased mortality in patients hospitalized with infection. The decision toinitiate therapy in patients with suspected infection is influenced by a variety of information, such as vital signs, and laboratoryresults. Identifying different patterns of events that lead to initiation is necessary to discover factors that could serve as targets forinterventions to expedite this process. We aimed to identify the most common sequences of events that precede antibioticordering and to quantify the time intervals between each event that contribute to antibiotic delays. Methods: This was aretrospective study of adult patients hospitalized at 4 community hospitals …

Hiv-Associated Nephropathy Presenting As The First Manifestation Of Hiv-2 Infection, Kamil Sardarli, Rania Daboul, Sumesh Khanal, Sami Zarouk
