Occult Renal Cell Carcinoma Presenting As A Palpable Supraclavicular Virchow's Node, Luke Perry, Jandie Schwartz, Gus Slotman, Omar Al Ustwani, Nandini Kulkarni

Rowan-Virtua Research Day

Occult papillary renal cell carcinoma (RCC) is a rare disease process in which there is evidence of metastatic kidney cancer, but no primary kidney tumor can be found on physical exam or imaging. The papillary subtype of RCC accounts for 10-15% of RCC’s. These lesions infrequently present as occult disease. A Virchow’s node can be positive for multiple cancer types, most notably gastric cancer, but also gallbladder, pancreas, kidneys, testicular, and prostate cancer. We describe a case of occult papillary renal cell carcinoma diagnosed by biopsy of a Virchow’s node.

Rowan-Virtua Research Day

This is a case of a 73-year-old Caucasian male presenting with an asymptomatic right adrenal mass.

Renal Cell Carcinoma (RCC) constitutes 80 to 85% of primary renal neoplasms. At presentation, up to 25% of patients with RCC will have evidence of metastases or locally advanced disease. [1] Patients will rarely present with any symptoms since the majority of patients are incidentally diagnosed due to radiologic procedures performed for other indications. RCC is considered the most lethal of urologic cancers because a patient without intervention who has stage IV metastatic disease has a 5-year survival rate of 23% in comparison to …


A Mathematical Investigation On Tumor-Immune Dynamics: The Impact Of Vaccines On The Immune Response, Jonathan Quinonez, Neethi Dasu, Mahboobi Qureshi May 2019

A Mathematical Investigation On Tumor-Immune Dynamics: The Impact Of Vaccines On The Immune Response, Jonathan Quinonez, Neethi Dasu, Mahboobi Qureshi

Rowan-Virtua Research Day

Mathematical models analyzing tumor-immune interactions provide a framework by which to address specific scenarios in regard to tumor-immune dynamics. Important aspects of tumor-immune surveillance to consider is the elimination of tumor cells from a host’s cell-mediated immunity as well as the implications of vaccines derived from synthetic antigen. In present studies, our mathematical model examined the role of synthetic antigen to the strength of the immune system. The constructed model takes into account accepted knowledge of immune function as well as prior work done by de Pillis et al. All equations describing tumor-immune growth, antigen presentation, immune response, and interaction …


A Rare Case Of A Non- Functioning Pancreatic Neuroendocrine Tumor, Yaser Khalid, Neethi Dasu, Richard Gordon May 2019

A Rare Case Of A Non- Functioning Pancreatic Neuroendocrine Tumor, Yaser Khalid, Neethi Dasu, Richard Gordon

Rowan-Virtua Research Day

Pancreatic neuroendocrine tumors (PNET) are very rare and represent about 1–2% of all pancreatic tumors. Non-functional PNET (NF-PNET) is incidentally discovered in most cases. Most NF-PNETs are found at an advanced stage because patients are mostly asymptomatic. We present a case of 32-yr-old female who initially presented with increasing abdominal girth, decreased mobility, and lower extremity swelling up to the hip and was found to have an advanced NF-PNET with metastatic disease to the pelvis and liver. There have been few studies directed toward early detection and management; Computed tomography (CT) is the imaging modality of choice as well as …

Gracilis Myocutaneous Flap For Perineal Defect Reconstruction After Left Hemivulvectomy For Locally Invasive Vulvar Cancer – A Case Report And A Literature Review, Nicolae Bacalbasa, Irina Balescu, Andreea Mereuta, Alina Tanase, Adriana Ghelmene, Mihaela Vilcu, Iulian Brezean

Journal of Mind and Medical Sciences

Performing radical surgery for locally advanced vulvar cancer is usually associated with the occurrence of large perineal defects. In order to provide a better healing process of the perineal wound, different reconstructive techniques have been proposed.

We present the case of a 63-year-old female patient diagnosed with locally advanced vulvar cancer for which a left hemivulvectomy with bilateral inguinal lymph node dissection was performed. After completion of the resection phase, the reconstruction with gracilis myocutaneous flap was performed. The patient developed a non-union of the flap. However, it slowly healed without any surgical re-intervention.

Gracilis myocutaneous flap seems to be …


Health Effects Of A Vegan Diet And Pediatric Cancer Prevention, Lindsay Wisehart Apr 2019

Health Effects Of A Vegan Diet And Pediatric Cancer Prevention, Lindsay Wisehart

Senior Honors Theses

Veganism is a diet which excludes consumption of all animal products. With proper planning and vitamin supplementation to ensure adequate intake of protein, fat, calcium, zinc, iron, and vitamins D and B12, a vegan diet is widely accepted as suitable for growing and developing children. The decreased levels of dairy, red and processed meats, fat, and protein, and increased levels of fruits and vegetables characteristic of a vegan diet have been shown to reduce risk of mortality and a number of diseases including adult and childhood cancer. Childhood cancer is the second leading cause of childhood death in Western society. …

The mitochondrial deoxynucleotide triphosphate (dNTP) is maintained by the mitochondrial deoxynucleoside salvage pathway and dedicated for the mtDNA homeostasis, and the mitochondrial deoxyguanosine kinase (DGUOK) is a rate-limiting enzyme in this pathway. Here, we investigated the role of the DGUOK in the self-renewal of lung cancer stem-like cells (CSC). Our data support that DGUOK overexpression strongly correlates with cancer progression and patient survival. The depletion of DGUOK robustly inhibited lung adenocarcinoma tumor growth, metastasis, and CSC self-renewal. Mechanistically, DGUOK is required for the biogenesis of respiratory complex I and mitochondrial OXPHOS, which in turn regulates CSC self-renewal through AMPK-YAP1 signaling. …

While the role of mitochondrial metabolism in controlling T-lymphocyte activation and function is becoming more clear, the specifics of how mitochondrial redox signaling contributes to T-lymphocyte regulation remains elusive. Here, we examined the global effects of elevated mitochondrial superoxide (O2-) on T-lymphocyte activation using a novel model of inducible manganese superoxide dismutase (MnSOD) knock-out. Loss of MnSOD led to specific increases in mitochondrial O2- with no evident changes in hydrogen peroxide (H2O2), peroxynitrite (ONOO-), or copper/zinc superoxide dismutase (CuZnSOD) levels. Unexpectedly, both mitochondrial and glycolytic metabolism showed significant reductions …

Pancreatic cancer is the third leading cause of cancer-related deaths in the USA. Pancreatic tumors are characterized by enhanced glycolytic metabolism promoted by a hypoxic tumor microenvironment and a resultant acidic milieu. The metabolic reprogramming allows cancer cells to survive hostile microenvironments. Through the analysis of the principal metabolic pathways, we identified the specific metabolites that are altered during pancreatic cancer progression in the spontaneous progression (KPC) mouse model. Genetically engineered mice exhibited metabolic alterations during PanINs formation, even before the tumor development. To account for other cells in the tumor microenvironment and to focus on metabolic adaptations concerning tumorigenic …

The deregulation of the actin cytoskeleton has been extensively studied in metastatic dissemination. However, the post-dissemination role of the actin cytoskeleton dysregulation is poorly understood. Here, we report that fascin, an actin-bundling protein, promotes lung cancer metastatic colonization by augmenting metabolic stress resistance and mitochondrial oxidative phosphorylation (OXPHOS). Fascin is directly recruited to mitochondria under metabolic stress to stabilize mitochondrial actin filaments (mtF-actin). Using unbiased metabolomics and proteomics approaches, we discovered that fascin-mediated mtF-actin remodeling promotes mitochondrial OXPHOS by increasing the biogenesis of respiratory Complex I. Mechanistically, fascin and mtF-actin control the homeostasis of mtDNA to promote mitochondrial OXPHOS. The …

Rab proteins play an essential role in regulating intracellular membrane trafficking processes. Rab activity is dependent upon geranylgeranylation, a post-translational modification that involves the addition of 20-carbon isoprenoid chains via the enzyme geranylgeranyl transferase (GGTase) II. We have focused on the development of inhibitors against geranylgeranyl diphosphate synthase (GGDPS), which generates the isoprenoid donor (GGPP), as anti-Rab agents. Pancreatic ductal adenocarcinoma (PDAC) is characterized by abnormal mucin production and these mucins play important roles in tumor development, metastasis and chemo-resistance. We hypothesized that GGDPS inhibitor (GGDPSi) treatment would induce PDAC cell death by disrupting mucin trafficking, thereby inducing the unfolded …

Pancreatic ductal adenocarcinoma (PDAC) has a five-year survival rate of <10% due in part to a lack of effective therapies. Pan-histone deacetylase (HDAC) inhibitors have shown preclinical efficacy against PDAC but have failed in the clinic due to toxicity. Selective HDAC inhibitors may reduce toxicity while retaining therapeutic efficacy. However, their use requires identification of the specific HDACs that mediate the therapeutic effects of HDAC inhibitors in PDAC. We determined that the HDAC1/2/3 inhibitor Mocetinostat synergizes with the HDAC4/5/6 inhibitor LMK-235 in a panel of PDAC cell lines. Furthermore, while neither drug alone synergizes with gemcitabine, the combination of Mocetinostat, LMK-235, and gemcitabine showed strong synergy. Using small interfering (si)RNA-mediated knockdown, this synergy was attributed to inhibition of HDACs 1, 2, and 6. Pharmacological inhibition of HDACs 1 and 2 with Romidepsin and HDAC6 with ACY-1215 also potently synergized with gemcitabine in a panel of PDAC cell lines, and this drug combination potentiated the antitumor effects of gemcitabine against PDAC xenografts in vivo. Collectively, our data show that inhibition of multiple HDACs is required for therapeutic effects of HDAC inhibitors and support the development of novel strategies to inhibit HDACs 1, 2, and 6 for PDAC therapy.

Type 1 diabetes (T1D) is a chronic autoimmune disease that results from destruction of pancreatic β-cells. T1D subjects were recently shown to harbor distinct intestinal microbiome profiles. Based on these findings, the role of gut bacteria in T1D is being intensively investigated. The mechanism connecting intestinal microbial homeostasis with the development of T1D is unknown. Specific gut bacteria such as Bacteroides dorei (BD) and Ruminococcus gnavus (RG) show markedly increased abundance prior to the development of autoimmunity. One hypothesis is that these bacteria might traverse the damaged gut barrier, and their constituents elicit a response from human islets that causes …

Inhibition of Cancer Stem Cells by Glycosaminoglycan Mimetics

In the United States cancer is the second leading cause of death, with colorectal cancer (CRC) being the third deadliest cancer and expected to cause over 51,000 fatalities in 2019 alone.1 The current standard of care for CRC depends largely on the staging, location, and presence of metastasis.2 As the tumor grows and invades nearby lymph tissue and blood vessels, CRC has the opportunity to invade not only nearby tissue but also metastasize into the liver and lung (most commonly).3 The 5-year survival rate …

Allogeneic haematopoietic stem cell transplantation currently represents the primary potentially curative treatment for cancers of the blood and bone marrow. While relapse occurs in approximately 30% of patients, few risk-modifying genetic variants have been identified. The present study evaluates the predictive potential of patient genetics on relapse risk in a genome-wide manner. We studied 151 graft recipients with HLA-matched sibling donors by sequencing the whole-exome, active immunoregulatory regions, and the full MHC region. To assess the predictive capability and contributions of SNPs and INDELs, we employed machine learning and a feature selection approach in a cross-validation framework to discover the …

Precision oncologic medicine is an emerging approach for cancer treatment that has recently taken giant steps in solid clinical practice. Recent advances in molecular diagnostics that can analyze the individual tumor's variability in genes have provided greater understanding and additional strategies to treat cancers. Although tumors can be tested by several molecular methods, the use of next-generation sequencing (NGS) has greatly facilitated our understanding of pediatric cancer and identified additional therapeutic opportunities. Pediatric tumors have a different genetic make-up, with a fewer number of actionable targets than adult tumors. Nevertheless, precision oncology in the pediatric population has greatly improved the …

The Tumor Microenvironment Regulates Retinoblastoma Cell Survival, Zachary K. Goldsmith

Theses and Dissertations (ETD)

Retinoblastoma (Rb) is the most common intraocular malignancy in children comprising 4% of all pediatric tumors. Early intervention increases survival rates up to 95% in developed countries; being survival rates associated to socio-economic status. Despite the high survival rates in developed countries, preservation of the eye and vision are continuing challenges in the management of Rb. Vitreous seeds constitute the greatest challenge in treatment of Rb. The unique location of these seeds within the vitreous makes them difficult to treat. Viable seeds showed reduced proliferative capacity and metabolism. making the majority refractory to current chemotherapeutics. This prompted the development of …

Hepatocellular carcinoma (HCC) is one of the deadliest cancers, with variable presentation, high chemotherapy resistance and early tumor recurrence. In this dissertation, we have systematically enriched, identified and characterized HCC cancer stem cells (CSCs) from 3 different HCC cell lines (Hepa1-6, HepG2, and Hep3B) using in vitro serum-free culture method. Enriched spheroids acquired CSC properties, primarily self-renewal capability, spheroid formation ability, and drug resistance. Heterogeneous CSCs enriched from Hepa1-6 cells demonstrated higher tumor initiation and proliferation capability in vivo, compared to control HCC cells in orthotopic immunocompetent mouse model. EpCAM+ CSCs were significantly enriched within heterogeneous Hepa1-6 CSC spheroids. Consequently, …

Transforming growth factor β (TGF-β) signaling transduces immunosuppressive biochemical and mechanical signals in the tumor microenvironment. In addition to canonical SMAD transcription factor signaling, TGF-β can promote tumor growth and survival by inhibiting proinflammatory signaling and extracellular matrix (ECM) remodeling. In this article, we review how TGF-β activated kinase 1 (TAK1) activation lies at the intersection of proinflammatory signaling by immune receptors and anti-inflammatory signaling by TGF-β receptors. Additionally, we discuss the role of TGF-β in the mechanobiology of cancer. Understanding how TGF-β dampens proinflammatory responses and induces pro-survival mechanical signals throughout cancer development is critical for designing therapeutics that …

Pheochromocytoma is a rare but life threatening adrenal secreting tumor. The infrequency with which it is encountered makes pheochromocytoma, especially in pregnancy, a formidable diagnostic challenge.

Although a pheochromocytoma is rare, it is good to keep it in differential diagnosis as a possible cause of labile BP with headaches and significant orthostatic BP. It is critical to recognize this condition to institute an appropriate therapy & surgical intervention to prevent mortality.

Breast cancer is the most commonly diagnosed cancer in women in the United States. Treatment options are wide-­‐ ranging based on a multitude of factors, including extent of disease and receptor positivity. Following treatment, a relapse-­‐free interval ≥ 2 years carries a more favorable prognosis.

We present a case involving a female with history of breast cancer and relapse-­free interval of 15 years who unfortunately presented with metastatic disease involving the liver, bone, and lymph nodes.
