Final Scholarly Project: Development Of Evidenced-Based Practice Guidelines For Female Patients Undergoing Anesthesia For Breast Cancer Surgery, Alexa High

Doctor of Nursing Practice Scholarly Projects

In the United States, the rate at which cancer is diagnosed is on the rise. In women, breast cancer is the second most common cancer diagnosis, following skin cancer, with approximately one in eight women developing breast cancer in their lifetime. When a patient receives a breast cancer diagnosis, the oncologic team will discuss the most suitable treatment plan for the patient, this often includes chemotherapy, radiation therapy, and surgery. Within the last few decades, research has shown that there may be a correlation between anesthetic medications and breast cancer metastasis. This project aims to create an evidence-based anesthesia guideline …

School of Medicine Publications and Presentations

Thyroid hormone receptor-interacting protein 13 (TRIP13) is involved in cancer progression, but its role in pancreatic ductal adenocarcinoma (PDAC) is unknown. Thus, we assessed the expression, functional role, and mechanism of action of TRIP13 in PDAC. We further examined the efficacy of TRIP13 inhibitor, DCZ0415, alone or in combination with gemcitabine on malignant phenotypes, tumor progression, and immune response. We found that TRIP13 was overexpressed in human PDACs relative to corresponding normal pancreatic tissues. TRIP13 knockdown or treatment of PDAC cells with DCZ0415 reduced proliferation and colony formation, and induced G2/M cell cycle arrest and apoptosis. Additionally, TRIP13 knockdown …

Insights Into The Molecular Roles Of Foxr2 In The Pathology Of Primary Pediatric Brain Tumors, Rajendra Gharbaran

Publications and Research

Forkhead box gene R2 (FOXR2) belongs to the family of FOX genes which codes for highly conserved transcription factors (TFs) with critical roles in biological processes ranging from development to organogenesis to metabolic and immune regulation to cellular homeostasis. A number of FOX genes are associated with cancer development and progression and poor prognosis. A growing body of evidence suggests that FOXR2 is an oncogene. Studies suggested important roles for FOXR2 in cancer cell growth, metastasis, and drug resistance. Recent studies showed that FOXR2 is overexpressed by a subset of newly identified entities of embryonal tumors. This review discusses the …

Tumor Matrix Stiffness Provides Fertile Soil For Cancer Stem Cells, Sadegh Safaei, Roya Sajed, Ahmad Shariftabrizi, Shima Dorafshan, Leili Saeednejad Zanjani, Masoumeh Dehghan Manshadi, Zahra Madjd, Roya Ghods

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

Matrix stiffness is a mechanical characteristic of the extracellular matrix (ECM) that increases from the tumor core to the tumor periphery in a gradient pattern in a variety of solid tumors and can promote proliferation, invasion, metastasis, drug resistance, and recurrence. Cancer stem cells (CSCs) are a rare subpopulation of tumor cells with self-renewal, asymmetric cell division, and differentiation capabilities. CSCs are thought to be responsible for metastasis, tumor recurrence, chemotherapy resistance, and consequently poor clinical outcomes. Evidence suggests that matrix stiffness can activate receptors and mechanosensor/mechanoregulator proteins such as integrin, FAK, and YAP, modulating the characteristics of tumor cells …

In Vitro Characterization Of A Novel Murine Model Of Cancerous Progression, Steven D. Scahill, Kelly Jean Sherman, Jessie J. Guidry, Whitney Walkowski, Theresa Nguyen, Durwood B. Ray, David H. Jones, Harry J. Gould, Dennis Paul

School of Graduate Studies Faculty Publications

To evaluate a potentially valuable tool to study cancer progression and metastasis, we characterized a novel murine model composed of a parental oncogene-transformed embryonic fibroblast line and five cell lines isolated from progressively advanced tumors. Lines derived from distant metastases displayed significantly greater rates of motility, invasiveness, and extracellular acidification than lines derived from a primary tumor or local metastases. A comprehensive proteomic analysis of these cells showed numerous oncogenes to be upregulated and tumor suppressors to be downregulated in the advanced lines, and provided novel targets for future examination. The first cell line capable of extravasation displayed particularly high …

The perinucleolar compartment (PNC) is a small nuclear body that plays important role in tumorigenesis. PNC prevalence correlates with poor prognosis and cancer metastasis. Its expression in pediatric Ewing sarcoma (EWS) has not previously been documented. In this study, we analyzed 40 EWS tumor cases from Caucasian and Hispanic patients for PNC prevalence by immunohistochemical detection of polypyrimidine tract binding protein and correlated the prevalence with dysregulated microRNA profiles. EWS cases showed staining ranging from 0 to 100%, which were categorized as diffuse (≥77%, n = 9, high PNC) or not diffuse (p= 0.017) and in patients who relapsed with …

Personalized Palliative And Survivorship Care For Patients With Metastatic Cancer Treated With Radiation Therapy, Sana Siddiqui, Luann Rowland, Emily Copel, Ashish Sangal, Vikram Soni, Patricia A. Eckardt, Johnny Kao

Faculty Publications: Nursing

While the benefits of early palliative care for patients with metastatic cancer are well established, cancer survivorship remains inadequately integrated into the care of patients with distant metastases. Moreover, the optimal model of care delivery is poorly defined. A prognostic model previously developed and validated at Good Samaritan University Hospital identified four groups of patients with metastatic solid tumor malignancy having very favorable, favorable, standard or unfavorable prognoses with median survival of 31, 14, 4 and 1 month, respectively. This framework holds promise for the personalized delivery of supportive, palliative and survivorship care services in the context of radiation therapy. …

Medical College Documents

Testicular choriocarcinomas make up less than 1% of all germ-cell tumors and are highly malignant, attributable to hematogenous spread. While the most common sites of metastasis are the lungs and liver, metastatic spread to the gastrointestinal tract is rare wherein patients may present with GI distress or even an upper GI bleed. In this report, we present a case of known testicular choriocarcinoma in a 40-year-old male who presented to the emergency room with severe anemia and a suspected upper GI bleed.

Research outputs 2022 to 2026

Background: Approximately 50% of uveal melanoma (UM) patients will develop metastatic disease depending on the genetic features of the primary tumour. Patients need 3–12 monthly scans, depending on their prognosis, which is costly and often non-specific. Circulating tumour DNA (ctDNA) quantification could serve as a test to detect and monitor patients for early signs of metastasis and therapeutic response. Methods: We assessed ctDNA as a biomarker in three distinct UM cohorts using droplet-digital PCR: (A) a retrospective analysis of primary UM patients to predict metastases; (B) a prospective analysis of UM patients after resolution of their primary tumour for early …

Polymeric Chloroquine In Metastatic Pancreatic Cancer Therapy, Rubayat Islam Khan

Theses & Dissertations

Hydroxychloroquine (HCQ) is an established drug that has been used for the treatment of multiple diseases, including malaria, rheumatoid arthritis, and lupus erythematosus. Several recently published studies have highlighted its beneficial use in various types of cancers, and a plethora of clinical trials are currently evaluating its use in cancer therapies, wherein some of the results look promising. The preclinical studies to date suggest HCQ can work effectively in conjunction with traditional cancer treatments, as it has been shown to sensitize tumor cells to a wide range of chemotherapeutic agents. Polymeric HCQ (PCQ), a macromolecular multivalent version of HCQ, has …

Principles Of Dormancy Evident In High-Grade Serous Ovarian Cancer, Trevor G. Shepherd, Frederick A. Dick

Paediatrics Publications

In cancer, dormancy refers to a clinical state in which microscopic residual disease becomes non-proliferative and is largely refractory to chemotherapy. Dormancy was first described in breast cancer where disease can remain undetected for decades, ultimately leading to relapse and clinical presentation of the original malignancy. A long latency period can be explained by withdrawal from cell proliferation (cellular dormancy), or a balance between proliferation and cell death that retains low levels of residual disease (tumor mass dormancy). Research into cellular dormancy has revealed features that define this state. They include arrest of cell proliferation, altered cellular metabolism, and unique …

Crosstalk Between Fatty Acid Metabolism And Tumour-Associated Macrophages In Cancer Progression, Noorzaileen Eileena Zaidi, Nur Aima Hafiza Shazali, Thean Chor Leow, Mohd Azuraidi Osman, Kamariah Ibrahim, Nik Mohd Afizan Nik Abd Rahman

BioMedicine

Over the last few decades, cancer has been regarded as an independent and selfsustaining progression. The earliest hallmarks of cancer comprise of sustaining proliferative signalling, avoiding growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis. Nonetheless, two emerging hallmarks are being described: aberrant metabolic pathways and evasion of immune destruction. Changes in tumour cell metabolism are not restricted to tumour cells alone; the products of the altered metabolism have a direct impact on the activity of immune cells inside the tumour microenvironment, particularly tumour-associated macrophages (TAMs). The complicated process of cancer growth is orchestrated …

Assessment Of A Size-Based Method For Enriching Circulating Tumour Cells In Colorectal Cancer, Sai Shyam Vasantharajan, Edward Barnett, Elin S. Gray, John L. Mccall, Euan J. Rodger, Michael R. Eccles, Fran Munro, Sharon Pattison, Aniruddha Chatterjee

Research outputs 2022 to 2026

Circulating tumour cells (CTC) from solid tumours are a prerequisite for metastasis. Isolating CTCs and understanding their biology is essential for developing new clinical tests and precision oncology. Currently, CellSearch is the only FDA (U.S. Food and Drug Administration)-approved method for CTC enrichment but possesses several drawbacks owing to a reliance on the epithelial cell adhesion molecule (EpCAM) and a resource-intensive nature. Addressing these shortcomings, we optimised an existing size-based method, MetaCell, to enrich CTCs from blood of colorectal cancer (CRC) patients. We evaluated the ability of MetaCell to enrich CTCs by spiking blood with CRC cell lines and assessing …

We report a case of acrometastasis to the left second phalanx in a 70-year-old woman with a history of invasive breast carcinoma that was in remission for four years. On initial encounter in the emergency department, she had pain and swelling over the proximal (PIP) and distal interphalangeal (DIP) joints with a lytic appearance on radiographs. A subsequent Adler PET scan demonstrated previously unknown metastatic disease in the right lower lung, mediastinal and hilar lymph nodes, …

Novel Regulators Of Cellular Secretion Alter The Tumor Microenvironment To Drive Metastasis, Rakhee Bajaj

Dissertations & Theses (Open Access)

Lung cancer is a highly aggressive disease responsible for ~25% of all cancer-related deaths, due in part to its proclivity to metastasize. Treating metastasis holds potential for improving patient survival but requires a deeper investigation into the underlying mechanisms. Some of these processes that can regulate metastasis are: (1) Oncogenic targets of epithelial micro-RNAs (miRNAs) are epigenetically de-repressed upon loss of the miRNAs during epithelial-to-mesenchymal transition (EMT) and in cancer. EMT confers plasticity and fitness to cancer cells promoting their survival through the metastatic cascade. This cascade and EMT are initiated by loss of the miRNA200 family (miR-200) and the …

Ghost Mitochondria Drive Metastasis Through Adaptive Gcn2/Akt Therapeutic Vulnerability, Jagadish C Ghosh, Michela Perego, Ekta Agarwal, Irene Bertolini, Yuan Wang, Aaron R Goldman, Hsin-Yao Tang, Andrew V Kossenkov, Catherine J Libby, Lucia R Languino, Edward F Plow, Annamaria Morotti, Luisa Ottobrini, Marco Locatelli, David W Speicher, M Cecilia Caino, Joel Cassel, Joseph M Salvino, Marie E Robert, Valentina Vaira, Dario C Altieri

Department of Cancer Biology Faculty Papers

Cancer metabolism, including in mitochondria, is a disease hallmark and therapeutic target, but its regulation is poorly understood. Here, we show that many human tumors have heterogeneous and often reduced levels of Mic60, or Mitofilin, an essential scaffold of mitochondrial structure. Despite a catastrophic collapse of mitochondrial integrity, loss of bioenergetics, and oxidative damage, tumors with Mic60 depletion slow down cell proliferation, evade cell death, and activate a nuclear gene expression program of innate immunity and cytokine/chemokine signaling. In turn, this induces epithelial-mesenchymal transition (EMT), activates tumor cell movements through exaggerated mitochondrial dynamics, and promotes metastatic dissemination in vivo. In …

Glycocalyx Mechanotransduction Mechanisms Are Involved In Renal Cancer Metastasis, Heriberto Moran, Limary M. Cancel, Peigen Huang, Sylvie Roberge, Tuoye Xu, John M. Tarbell, Lance L. Munn

Publications and Research

Mammalian cells, including cancer cells, are covered by a surface layer containing cell bound proteoglycans, glycoproteins, associated glycosaminoglycans and bound proteins that is commonly referred to as the glycocalyx. Solid tumors also have a dynamic fluid microenvironment with elevated interstitial flow. In the present work we further investigate the hypothesis that interstitial flow is sensed by the tumor glycocalyx leading to activation of cell motility and metastasis. Using a highly metastatic renal carcinoma cell line (SN12L1) and its low metastatic counterpart (SN12C) we demonstrate in vitro that the small molecule Suberoylanilide Hydroxamic Acid (SAHA) inhibits the heparan sulfate synthesis enzyme …
