Upper Urinary Tract Transitional Cell Carcinoma And Lymph Node Involvement: Pre And Post Operative Outcomes, Brittney Henderson, Son Young, Mark Quiring, Scott Serpico, Edward Wu, Emma Troyer, Ryan Moriarty, Thomas Mueller, Gordon Brown

Research Day

Background: Upper urinary tract transitional cell carcinomas (UUT-TCC) comprise any malignancy arising from the renal pelvis to distal ureter. These cancers account for approximately 5-10% of all urothelial tumors. Two-thirds of cases are invasive with an estimated 5-year survival rate less than 50%. Pathologic staging, invasion into local structures, and lymph node involvement influence the overall survival rate. Lymph node dissection (LND) is associated with higher overall survival rates in UUT-TCC patients, likely by decreasing regional lymph node metastasis. Current literature suggests that removing eight to ten regional lymph nodes may improve survival. The outcomes of upper urinary tract malignancies …

Modified Excisional Biopsy Technique For Confirmed Or Highly Suspected Melanomas, Batul Momin, Katrina Hansen

Research Day

There are a variety of biopsy techniques for sampling confirmed or highly suspicious melanomas, including excisional, scoop-shave or “saucerization”, shave, and punch biopsy. Herein, we present a case in which a combination approach of saucerization and excisional biopsy was used for a patient with an inadequately sampled melanoma. In the literature, excisional biopsy remains the gold standard for diagnosing melanoma. This technique is accomplished with a full-thickness, fusiform removal of the lesion with a scalpel to the level of adipose tissue (2). The drawback to this technique is the slightly distorted anatomy that can occur during wound closure. Albeit rare, …

A Seemingly Low Risk Patient Develops Urosepsis As A Complication Of Transrectal Prostate Biopsy: A Case Study, Nicole Peritz, Gabrielle Oquendo, Yuhyun Kang, Elijah Humphries, Joy Zarandy

Research Day

Background:

Prostate cancer (PCa) is the most common cancer in men, and the second most common cause of cancer deaths in the United States. Approximately 1 million Americans undergo prostate biopsies annually, with 97% undergoing the transrectal prostate biopsy (TRPB). While TRPB is reliable and relatively low risk, nearly 7% of patients develop infectious complications, with 3% requiring hospitalization due to sepsis. Risk factors for developing infection post-TRPB include antibiotic resistance, >10 biopsy cores, diabetes mellitus, indwelling catheter, and African-American ethnicity. Identifying risk factors, considering a transperineal biopsy approach, and utilizing pre-procedural practices like rectal sterilization, screening urinalysis, prophylactic antibiotics, …

Rare Presentation Of Metastatic Hepatocellular Carcinoma In The Finger: Case Report And Review Of Literature, F. Rhana Mousavi, Bassem Bekheit, Emon Alavi, Nick A. Hirad, Abanoub Gabra

Research Day

Hepatocellular carcinoma (HCC) is a primary tumor of the liver that primarily develops in the setting of chronic liver disease. HCC is difficult to diagnose due to it requiring the use of multiple imaging modalities with the goal to detect tumors when they are less than or equal to 2 cm in size to allow all possible treatment options to be used. Herein, we discuss a 69-year-old male with stage IV liver cancer residing in hospice presenting with left middle finger osteomyelitis and extreme pain. Radiology revealed a destructive lesion but pathology provided the diagnosis of metastatic hepatocellular carcinoma in …

Research Day

INTRODUCTION: Lung cancer is the most commonly diagnosed cancer amongst both genders, currently accounting for about 18% of all cancer deaths.

OBJECTIVES: The overall purpose of this study was to evaluate the pathology associated with the patient’s cause of death, cardiorespiratory failure and lung cancer. The secondary aims of this study were to confirm the presence of malignant neoplasms within a human cadaver, determine the type of cancer present, and take specimens for histological examination to evaluate the patient’s cause of death.

METHODS: This is a case report from one of the cadavers in the Gross Anatomy laboratory at the …

A Cadaveric Case Study On Metastatic Breast Cancer Pathology, Janai L. Groves, Haley B. Garrett, Savannah J. Finley, Jada M. Glenn, Itza M. Garcia, Shiv Dhiman, Savita Arya

Research Day

INTRODUCTION: Breast cancer is the second most common cancer among women in the United States. The exact etiology of breast cancer is unknown, but over 70% of breast cancer cases involve only two risk factors: being a woman and being over the age of 50. Women with a family history of breast cancer, as well as women who experience early menopause, have an even greater risk of developing this disease. When considering racial demographics, African-American women have a 4-8% lower incidence rate of breast cancer than Caucasian women but are 40% more likely to die from the disease. Breast cancer …

Cadaveric Study: Sign Of Leser-Trélat Associated With Breast Cancer, Brigitte L. Cochran, Shiv Dhiman, Savita Arya

Research Day

INTRODUCTION: Seborrheic keratoses (SK) is considered the most common benign skin lesions found in individuals that are middle aged and older. In dermatology practice, these lesions pose no threat to the individual but can be concerning for cosmetic and underlying malignancy reasons when they cover most of the skin surface. Of specific concern is the sign of Leser-Trélat, which has been documented as a cutaneous harbinger of underlying malignancy associated with proliferation of the size and/or number seborrheic keratoses. This rare sign is usually caused by malignancies such as gastrointestinal adenocarcinoma and lung, kidney, liver, pancreatic cancer or malignant melanoma. …

A Unique Case Of Atrial Fibrillation Secondary To Squamous Cell Lung Carcinoma, Mohammad J. Malik, Emily K. Wilson, Vijay Bandhakavi

Research Day

Atrial fibrillation (AF) is widely considered to be the most prevalent cardiac arrhythmia with an incidence of roughly 1-2% in the United States alone. The incidence of AF has been known to increase with advancing age and thus presents a significant burden on healthcare systems across the globe. AF arises as a result of several mechanisms including structural changes that occur to the heart overtime. Here we present a case in which a 63-year-old male with no past medical history except heavy tobacco use presented to the emergency department complaining of shortness of breath. He also endorsed having palpitations and …

A Combined Radio-Immunotherapy Regimen Eradicates Late-Stage Melanoma In Mice., Sritha Moram, Alexander Rakhmilevich, Noah Tsarovsky, Mildred Felder, Amy Erbe, Alex Pieper, Jen Zaborek, Emily Cheng, Cole Witt, Paul Sondel

Research Day

Advanced cancers are typically resistant to treatment, which leads to most experimental cancer immunotherapy approaches being tested against smaller tumors. In this study, we show that even late-stage, weakly immunogenic mouse B78 melanomas, with tumor volumes of 1500-2000 mm3, can be eradicated by a combined radio-immunotherapy regimen (CRIR) which includes local radiotherapy, intratumoral interleukin 12, slow-release systemic interleukin 2 and checkpoint blockade with anti-CTLA-4 antibody. Flow analysis of the tumors revealed a reduction in T regulatory (Treg) cells and an increase in CD8/Treg ratios following CRIR. T cell depletion did not prevent the rapid shrinkage of treated tumors, but suppressed …

Prolonged Length Of Stay In Illeal Conduit Compared To Neobladder Diversion In Radical Cystectomy Patients For Bladder Cancer, Ryan J. Moriarty, Young Son, Brian Thomas, Ronald Clearie, Lance Earnshaw, Dayna Devincentz, Thomas Mueller

Research Day

Background:

Radical cystectomy and urinary diversion has become the standard treatment for invasive and complicated malignancies of the bladder, urethra, and ureters. [1] Robotic-assisted radical cystectomy (RARC), introduced in the last decade, has been associated with favorable perioperative outcomes when compared to open radical cystectomy. Yet little is known about how different urinary diversion types compare in regards to length of hospital stay, readmission rates, and perioperative course. This data analysis seeks to identify the statistically significant differences in postoperative course of ileal conduit versus neobladder among patients with staged bladder cancer.

Comparison Of The Inhibition Of An Oct3 Transporter Inhibitor, Nilotinib, On Doxorubicin’S Effects On Cardiac And Cancer Cell Lines, Zachary G. Tan, Juliet Melnik, Aakash Belsare, James Huang, Meagan Lyons, Kimberly Dowes, Gurpreet Kaur, Lindon H. Young, Robert J. Barsotti, Qian Chen

Research Day

Introduction

Doxorubicin (DOX)-induced cardiotoxicity remains a significant barrier limiting its clinical application due to a lack of effective resolution. Targeting how DOX enters cardiac and cancer cells is a promising new strategy. Research suggests that an OCT3 transporter significantly contributes to DOX entry into the heart tissue. By contrast, it expresses much lower on breast cancer cell lines. Moreover, Nilotinib (NIB) can suppress OCT3 transporter function by 80%. Therefore, exploring the impact of NIB on the DOX’s effects on cardiac and cancer cell lines by altering DOX intracellular accumulation is intriguing.

Objective

First, we would establish a dose-response curve of …
