The Impact Of Intralesional 5-Fluorouracil In The Treatment Of Keloid Scars, Madeline Derham

Master of Science in Physician Assistant Studies Capstone Presentations (Center City)

Background

- The American Academy of Dermatology (AAD) defines a keloid scar as a type of raised scar extending past the initial area of injury¹

- Approximately 10% of the general population affected - significant risk factors include +family history, darker skin tones, mechanism of injury (burn, surgical)³

- Symptom presentation: pain, pruritus, burning, increased sensitivity³

- Varying existing treatment methods with high resistance and recurrence rates leading to no agreed upon standard approach⁵

• Most widely adopted method currently : intralesional (ILS) steroid ^injection5

The Effects Of Metronomic And Maximum-Tolerated Dose Chemotherapy In Colorectal Cancer Angiogenesis: A Combined Approach Using Endoscopic Diffuse Reflectance Spectroscopy And Mrna Expression, Ariel Isaac Mundo Ortiz

Graduate Theses and Dissertations

Colorectal cancer (CRC) continues to be one of the most incident and deadliest types of cancer worldwide. Chemotherapy has proven effective to reduce tumor burden for CRC patients, but there are several disadvantages associated with the use of mainstay maximtolerated dose (MTD) chemotherapeutic strategies. Metronomic chemotherapy (MET) has been developed as an alternative that addresses the shortcomings of maximum-tolerated dose chemotherapy but so far its effectiveness as a neoadjuvant strategy for CRC has not been explored.

This dissertation uses a combined optics and molecular biology approach (using diffuse reflectance spectroscopy and mRNA expression) to study the changes in angiogenesis and …

Real-World Evaluation Of Universal Germline Screening For Cancer Treatment-Relevant Pharmacogenes, Megan L. Hutchcraft, Nan Lin, Shulin Zhang, Catherine Sears, Kyle Zacholski, Elizabeth A.

The purpose of this study was to determine the frequency of clinically actionable treatment-relevant germline pharmacogenomic variants in patients with cancer and assess the real-world clinical utility of universal screening using whole-exome sequencing in this population. Cancer patients underwent research-grade germline whole-exome sequencing as a component of sequencing for somatic variants. Analysis in a clinical bioinformatics pipeline identified clinically actionable pharmacogenomic variants. Clinical Pharmacogenetics Implementation Consortium guidelines defined clinical actionability. We assessed clinical utility by reviewing electronic health records to determine the frequency of patients receiving pharmacogenomically actionable anti-cancer agents and associated outcomes. This observational study evaluated 291 patients with …

Recent Advances In Designing 5-Fluorouracil Delivery Systems: A Stepping Stone In The Safe Treatment Of Colorectal Cancer, Elaheh Entezar-Almahdi, Soliman Mohammadi-Samani, Lobat Tayebi, Fatemeh Farjadian

School of Dentistry Faculty Research and Publications

5-Fluorouracil (5-FU) has become one of the most widely employed antimetabolite chemotherapeutic agents in recent decades. It is considered a first line antineoplastic agent for the treatment of colorectal cancer. Unfortunately, chemotherapy with 5-FU has several limitations, including its short half-life, high cytotoxicity and low bioavailability. In order to overcome the drawbacks of 5-FU and enhance its therapeutic efficiency, many scientific groups have focused on designing a new delivery system to successfully deliver 5-FU to tumor sites. We provide a comprehensive review on different strategies to design effective delivery systems, including nanoformulations, drug-conjugate formulations and other strategies for the delivery …

Pectin-Tannic Acid Nano-Complexes Promote The Delivery And Bioactivity Of Drugs In Pancreatic Cancer Cells, Sumeet S. Chauhan, Advait B. Shetty, Elham Hatami, Pallabita Chowdhury, Murali M. Yallapu

School of Medicine Publications and Presentations

Pancreatic cancer (PanCa) is a lethal disease. Conventional chemotherapies for PanCa offer severe systemic toxicities. Thus, the development of a successful nanomedicine-based therapeutic regimen with augmented therapeutic efficacy is highly sought. Naturally occurring pectin and modified pectin-based drug delivery systems exhibit remarkable self-targeting ability via galactose residues to various cancer cells. Herein, we developed and used an innovative approach of highly stable nanocomplexes based on modified pectin and tannic acid (MPT-NCs). The nanocomplex formation was enabled by strong intermolecular interactions between pectin and tannic acid under very mild conditions. These nanocomplexes were characterized by particle size and morphology (DLS, TEM, …

Efficacy Of Combined 5-Fluorouracil And Photodynamic Therapy In Glioma Spheroids, Karanjit Singh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Standard treatment regimens consisting of surgery, radiation and chemotherapy have proven ineffective for the treatment of high-grade gliomas such as glioblastoma multiforme (GBM). An effective cure requires elimination of nests of tumor cells that have migrated from the resection margin and infiltrated normal brain. A number of localized therapies, including light-based approaches such as photodynamic therapy (PDT) and photochemical internalization (PCI) are currently under investigation for the management of GBM patients.

Several studies have demonstrated a high degree of synergy between PDT and bleomycin, via the PCI mechanism, in a variety of in vitro and in vivo models, including glioma …

The Future Of 5-Fluorouracil Treatment Of Colorectal Cancer: Translating A Better Understanding Into Improved Patient Care, Nathan Smits

Theses and Graduate Projects

5-fluorouracil (5-FU) is a pyrimidine analog that has been successfully employed in anticancer therapy for over forty years. Over the past several decades, researchers have characterized its cellular and clinical pharmacology and uncovered multiple mechanisms of action, which include the inhibition of thymidylate synthase (TS) and incorporation of its metabolites into DNA and RNA. The purpose of this quantitative systemic review was to summarize and evaluate what is known of these mechanisms to determine which are of most significance in the anticancer effects of 5-FU in metastatic colorectal cancer (mCRC) patients. A literature search of peer-reviewed articles dating back to …

Is The Use Of Triamcinolone (Tac) In Combination With 5-Fluorouracil (5-Fu) More Effective Than Tac Alone In The Treatment Of Keloid Scars?, Jenna A. Barreto

PCOM Physician Assistant Studies Student Scholarship

Objective: The objective of the selective EBM review is to determine whether or not “Is the use of triamcinolone (TAC) in combination with 5-fluorouracil (5-FU) is more effective than TAC alone in the treatment of keloid scars?”

A New Angiogenesis Prognostic Index With Vegfa, Plgf, And Angiopoietin1 Predicts Survival In Patients With Advanced Gastric Cancer, Sedef Hande Aktaş, Hakan Akbulut, Ozan Yazici, Nurullah Zengi̇n, Hali̇me Nalan Akgün, Zeki̇ Üstüner, Fi̇kri̇ İçli̇

Turkish Journal of Medical Sciences

Background/aim: The role of angiogenic factors in gastric cancer is not clear. We aimed to assess the role of vascular endothelial growth factor A (VEGFA), angiopoietin 1 (Ang-1), and placental growth factor (PlGF) in the prognosis of patients with advanced gastric cancer. Materials and methods: Thirty consecutive patients treated with a modified DCF (docetaxel, cisplatin, and fluorouracil) regimen were included in the study. The plasma VEGFA, Ang-1, and PlGF levels of the patients before treatment and following two cycles of chemotherapy were measured and evaluated as prognostic factors. Results: Poor performance status and lower Ang-1 levels were correlated with poor …
