Extrathyroidal extension (ETE) in patients with papillary thyroid carcinoma (PTC) is an indication of disease progression and can influence treatment aggressiveness. This meta-analysis assesses the diagnostic accuracy of ultrasonography (US) in detecting ETE. A systematic review and meta-analysis were performed by searching PubMed, Embase, and Cochrane for studies published up to April 2022. The pooled sensitivity, specificity, and diagnostic odds ratio (DOR) were calculated. The areas under the curve (AUC) for summary receiver operating curves were compared. A total of 11 studies analyzed ETE in 3795 patients with PTC. The sensitivity of ETE detection was 76% (95%CI = 74–78%). The …

Seeing The Big Picture: System Architecture Trends In Endoscopy And Led-Based Hyperspectral Subsystem Intergration, Craig M. Browning

<strong> Theses and Dissertations </strong>

Early-stage colorectal lesions remain difficult to detect. Early development of neoplasia tends to be small (less than 10 mm) and flat and difficult to distinguish from surrounding mucosa. Additionally, optical diagnosis of neoplasia as benign or malignant is problematic. Low rates of detection of these lesions allow for continued growth in the colorectum and increased risk of cancer formation. Therefore, it is crucial to detect neoplasia and other non-neoplastic lesions to determine risk and guide future treatment. Technology for detection needs to enhance contrast of subtle tissue differences in the colorectum and track multiple biomarkers simultaneously. This work implements one …

Ribonucleotide Reductase Subunit Switching In Hepatoblastoma Drug Response And Relapse, Anthony Brown

Theses and Dissertations (ETD)

Hepatoblastoma is the most common primary liver cancer in infants and young children. Despite being a very rare cancer that accounts for only 0.5-2% if all childhood cancer cases, HB has the largest increase in incidence among childhood cancers in the United States and worldwide. The five-year survival rate of children with the aggressive forms of HB, including those that have developed metastatic or recurrent diseases, is less than 40% due to the lack of effective treatment. We aim to identify targetable mechanisms underlying the progression and drug resistance of high-risk HB. Our recent work on HB mouse and organoid …

Cardiac Metastasis After Curative Treatment Of Hepatocellular Carcinoma: Risk Factors, Treatment Options, And Prognosis, Gaurav Jain, Mathew Otto, Mubeen Khan Mohammed Abdul, Manpreet Chadha, Ajay Sahajpal

Journal of Patient-Centered Research and Reviews

Hepatocellular carcinoma (HCC) is primary hepatic malignancy with a high incidence of recurrence. The risk of recurrence directly correlates to patient’s overall prognosis. Management of advanced HCC involves a combination of surgical resection, locoregional therapy, and systemic treatment. Distant metastases are rare, and intraventricular cardiac metastases are even more infrequent. This brief review details an illustrative case of cardiac metastasis after curative treatment of primary HCC and then summarizes the literature on risk factors, treatment options, and patient prognosis in the setting of distant metastases from HCC. Prognosis of metastasis to the heart is generally poor, and available evidence emphasizes …

Otulin's Novel Regulatory Mechanisms In Genotoxic And Inflammatory Nf-Kb Signaling, Mingqi Li

Theses and Dissertations (ETD)

Triple negative breast cancer (TNBC) is aggressive but cannot be treated with hormone therapy or molecular therapy due to the lack of a target. Chemotherapy is a systemic treatment that works by attacking rapidly growing cells, which is initially more effective for TNBC patients than those individuals with the hormone receptor-positive breast cancer. However, patients with TNBC tend to develop resistance to chemo drugs, called chemoresistance. After years of effort, the signaling pathways involved in TNBC chemoresistance are gradually revealed, including the nuclear factor-kappa B (NF-kB) pathway. Transcription factor NF-kB is widely involved in cancer development and progression, and its …

Targeting Myeloid Protein Kinase C Signaling To Overcome Immune Suppression And Improve Immunotherapy In Cancer, Mehdi Chaib

Theses and Dissertations (ETD)

Checkpoint immunotherapy unleashes T cell antitumor potential which has revolutionized cancer treatment showing unprecedented long-term responses. However, most patients do not respond to immunotherapy which often correlates with a dysfunctional or immunosuppressive myeloid compartment. Immunosuppressive myeloid cells comprise Myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs) and can suppress T cells via production of immunosuppressive factors. Conversely, efficient cytotoxic T cell priming is dependent on the ability of antigen-presenting cells (APCs), mainly conventional dendritic cells (cDCs) and macrophages, to present or cross-present tumor antigens to T cells. Thus, targeting immunosuppressive myeloid cells while simultaneously enhancing APCs represents a promising strategy …

The Role And Immunogenicity Of Cbfa2t3-Glis2 In Pediatric Acute Megakaryoblastic Leukemia, Elizabeth A. Garfinkle

Theses and Dissertations (ETD)

CBFA2T3-GLIS2 is the most prevalent fusion oncogene in pediatric acute megakaryoblastic leukemia in patients without Down syndrome (non-DS-AMKL) and is associated with an event free survival of only 8% even with high intensity chemotherapy and stem cell transplant in first remission. A cryptic inversion event on chromosome 16 joins the three nervy homology regions (NHR) of CBFA2T3 to the five zinc fingers of GLIS2. This configuration enables the encoded chimeric transcription factor to bind GLIS consensus sequences throughout the genome and recruit transcriptional activators and repressors to alter gene expression and enhance self-renewal capability. Few cooperating mutations have been identified …

Master of Occupational Therapy Student Critically Appraised Topics

The purpose of our project is to determine the feasibility and effectiveness of a prehabilitation (prehab) program for patients undergoing breast cancer surgery as compared to only receiving post-surgical rehabilitation. Our clinical mentor has recently obtained certification as a lymphedema specialist and is assisting with the opening of an outpatient mastectomy clinic through the Methodist University systems. Through our research process, we critically appraised two Level II articles, two Level III articles, and one Level IV article. Positive outcomes related to the feasibility were identified, however there is limited significant evidence supporting the effectiveness of the intervention. We recommend using …

Factors And Outcomes Contributing To Pelvic Lymph Node Dissection In Non-Muscle Invasive Bladder Cancer, Young Son, Brian Thomas, Lance Earnshaw, Mark Quiring, Erica Martel, Benjamin Fink, Raeann Dalton, Thomas Mueller, Philip Dorsey

Rowan-Virtua Research Day

Bladder cancer represents the 6th most common for men and is classified into muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC). NMIBC (T1, Ta, Tis), accounting for approximately 75% of new bladder cancer diagnoses, is limited to the mucosa, submucosa, and lamina propria. Studies have approximated the rate of recurrence in NMIBC between 50 - 70%, which sometimes progresses to muscle invasive disease. Management of NMIBC ranges from surveillance, intravesical chemotherapy to radical cystectomy (RC) and is dependent upon the TNM staging and grading of the tumor. Clinically, staging is determined via imaging, physical exam, and histology on transurethral …

Management Of Late-Stage Ewingoid Dedifferentiated Liposarcoma Of The Spermatic Cord With Emergent Complications: A Case Report, Raeann Dalton, Abdullah Junayed, Brian Thomas, Young Son, Megan Donlick, Kathryn Goettle, Lance Earnshaw, Thomas Mueller

Rowan-Virtua Research Day

Liposarcoma (LS), a malignant tumor of adipose origin, is the most common soft tissue sarcoma (STS), and can develop within any soft tissue. It rarely occurs in the paratesticular region, and accounts for 3-7% of spermatic cord tumors. Dedifferentiated liposarcoma (DDLS) and well-differentiated liposarcoma (WDLS) account for two of the five subtypes of LS, with dedifferentiation occurring in 20% of cases. There have been 66 cases of DDLS of the spermatic cord reported to date, but none present with a 22/22q trisomy without the fusion or rearrangement that commonly produces these aggressive tumors.

Accurate diagnosis of LS of the spermatic …

Interaction Of Fluorescent Probes With Sirtuin Proteins, James Fusco, Brian P Weiser

Rowan-Virtua Research Day

Sirtuins are a class of proteins belonging to the Sir2 (Silencing information regulator 2) family of NAD+ dependent protein lysine deacylases. Different Isoforms (SIRT1-SIRT7) differ in their specific deacylase activity and cellular location. They have roles in DNA repair, glucose metabolism, and cellular proliferation which make them highly desirable targets for carcinoma therapeutics. We previously used 1-aminoanthracene’s (AMA) fluorescent properties when bound with SIRT2 (Kd of 37 μM) to develop a high-throughput screen to identify novel ligands that inhibit SIRT2’s enzymatic activities. We hope to reveal other potential probes for future high-throughput screening with all the sirtuin isotopes. 1-AMA’s fluorescence …

Increasing Colorectal Cancer Screening Adherence: A Scoping Review, Megan E. Billingsley Bsn, Rn, Tiameria T. Ford Bsn, Rn, Mikayla E. Vican Bsn, Rn, Diana Dedmon Dnp, Aprn, Fnp-Bc

Doctor of Nursing Practice Projects

Purpose/Background Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Rates have steadily increased in recent years due to high rates of obesity, smoking, and sedentary lifestyles. Screening for the disease can lead to early detection and reduced morbidity/mortality, yet screening rates remain low. Existing literature is extensive in discussing methods to increase CRCS adherence; therefore, a scoping review allows for increased understanding of barriers to CRCS and how to address those barriers to increase screening compliance.

Methods A literature search was completed from September 2020 to October 2021. Multiple databases were used, including …

Evaluation Of The Effectiveness Of An On-Site Referral System To Increase Mammography Screening Compliance: Scoping Review, Piper Black, Elizabeth R. Upchurch, Ravina Patel, Vicki Chandler Dnp, Aprn, Fnp-Bc

Doctor of Nursing Practice Projects

Purpose/Background Early detection of breast cancer through routine mammography screenings has increased the 5-year survival rate to 99% for women with cancer in the localized stage (American Cancer Society, 2021). However, this survival rate is lessened amongst women in the rural population (Leung et al., 2014). This scoping review investigates health disparities to identify interventions that improve mammography rates for women residing in rural areas.

Methods A scoping review was performed using an exclusive search for peer-reviewed mammography and rural health sources. Search phrases included were, ('Mammogram screening in rural areas'), ('Health care disparities in rural areas'), ('Secondary prevention in …

Targeting Protein Degradation To Uncover Novel Oncoprotein Drivers Of Acute Leukemia, Fatemeh Keramatnia

Theses and Dissertations (ETD)

Acute Lymphoblastic Leukemia (ALL), the most common childhood cancer and the second most common acute leukemia in adults, arises from clonal expansion of undifferentiated lymphoid precursor cells in bone marrow. Despite the extensive knowledge on its cytogenetic and molecular biology, ALL treatment remains highly challenging especially after relapse. Conventional chemotherapy has shown significant improvement in overall survival rates of pediatric patients up to 90%, however, treatment failure due to ALL relapse occurs in 15-20% of the cases. On the other hand, adults and elderly patients with ALL are considered difficult to treat populations with the 5-year overall survival of 30–40%. …
