Resection And Reconstruction Of Ewing Sarcoma Of The Cuboid Utilizing Vascularized Fibular Autograft: A Case Report, Brandon Cunha, Alexandre Arkader

Rowan-Virtua Research Day

Ewing Sarcoma (EWS) rarely presents in the bones of the foot, and particularly in the cuboid, making it an exceedingly rare occurrence. We present the case of a 7-year-old female diagnosed with EWS of the right cuboid, detailing the management and outcomes of this rare presentation. The patient, now almost 5 years post-initial local control, exhibits restored foot function, a normalized gait, and no evidence of disease recurrence. This case underscores the potential for preserving lower extremity function and improving postoperative quality of life in rare presentations of EWS through innovative reconstruction strategies.

Case Report: An Emergency Department Presentation Of An Ovarian Teratoma, David Marconi, Zamron Masih May 2024

Case Report: An Emergency Department Presentation Of An Ovarian Teratoma, David Marconi, Zamron Masih

Rowan-Virtua Research Day

A teratoma (from the Greek terato for “monster” and onkoma for “mass” or “swelling”) is a type of neoplasm composed of tissues from two or three germ layers. Mature cystic teratomas (MCTs) constitute 70% of all ovarian neoplasms. They typically present with nonspecific symptoms such as pain and nausea. They account for approximately 2% of all primary ovarian malignant cancers and are predominately diagnosed via ultrasound. Computed tomography may be necessary if malignancy is suspected. Larger size warrants a higher suspicion of malignancy. Management is symptom control and ultimately, surgical removal. Prognosis is generally excellent, provided there is no malignant …

The Clinical Definition And Characterization Of Field Of Cancerization In Patients With Actinic Keratoses, Stuti Prajapati, Christina Kontzias, Mallory Zaino, Steven Feldman

Rowan-Virtua Research Day

Introduction: Chronic UV radiation affects the entire area of skin exposed, leading to visible actinic keratoses (AK) and subclinical changes in the surrounding skin. AKs are hyperkeratotic lesions, with a 0.025-16% risk of transforming into squamous cell carcinoma (SCC).1 Cellular atypia around AKs is the field of cancerization (FOC). Topical AK therapies can treat the FOC, while destructive treatments address visible lesions. FDA-approved products may be approved for field sizes up to 25 cm2.1,2

Objective: To characterize the FOC and assess the correlation between the FOC and number of AKs.

Methods: 100 patients with AKs were recruited. FOC was defined …

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 …

USP18 (ubiquitin-specific protease 18) removes ubiquitin-like modifier interferon stimulated gene 15 (ISG15) from conjugated proteins. USP18 null mice in a FVB/N background develop tumors as early as 2 months of age. These tumors are leiomyosarcomas and thus represent a new murine model for this disease.

Recombinant soluble TRAIL and agonistic antibodies against TRAIL receptors (DR4 and DR5) are currently being created for clinical cancer therapy, due to their selective killing of cancer cells and high safety characteristics. However, resistance to TRAIL and other targeted therapies is an important issue facing current cancer research field. An attractive strategy to sensitize resistant malignancies to TRAIL-induced cell death is the design of small molecules that target and promote caspase 8 activation. For the first time, we describe the discovery and characterization of a small molecule that directly binds caspase 8 and enhances its activation when combined with TRAIL, …

Predicting Targeted Drug Combinations Based On Pareto Optimal Patterns Of Coexpression Network Connectivity, Nadia M. Penrod, Casey S. Greene, Jason H. Moore

Dartmouth Scholarship

Molecularly targeted drugs promise a safer and more effective treatment modality than conventional chemotherapy for cancer patients. However, tumors are dynamic systems that readily adapt to these agents activating alternative survival pathways as they evolve resistant phenotypes. Combination therapies can overcome resistance but finding the optimal combinations efficiently presents a formidable challenge. Here we introduce a new paradigm for the design of combination therapy treatment strategies that exploits the tumor adaptive process to identify context-dependent essential genes as druggable targets. We have developed a framework to mine high-throughput transcriptomic data, based on differential coexpression and Pareto optimization, to investigate drug-induced …

The up-regulation of cell surface receptors has become a central focus in personalized cancer treatment; however, because of the complex nature of contrast agent pharmacokinetics in tumor tissue, methods to quantify receptor binding in vivo remain elusive. Here, we present a dual-tracer optical technique for noninvasive estimation of specific receptor binding in cancer. A multispectral MRI-coupled fluorescence molecular tomography system was used to image the uptake kinetics of two fluorescent tracers injected simultaneously, one tracer targeted to the receptor of interest and the other tracer a nontargeted reference. These dynamic tracer data were then fit to a dual-tracer compartmental model …
