A Social Media Campaign And Web-Based Survey About Prostate Cancer Genetics: Mixed Methods Study, Amy Leader, Stacy Loeb, Preethi Selvan, Ashley Hunter, Rebecca Hartman, Scott Keith, Veda Giri

Department of Medical Oncology Faculty Papers

BACKGROUND: Germline genetic variants are important for prostate cancer (PCa) management and hereditary cancer risk assessment, but testing is underused. Furthermore, patients are often unaware of the genetic connections to PCa. Social media is increasingly serving as a source of awareness for health information and a method to gather data from a large population.

OBJECTIVE: There were three objectives: to (1) create and test social media messages related to PCa genetics and genetic testing, (2) determine which social media message was most engaging, and (3) assess knowledge of and attitudes toward PCa genetic testing through an online survey using the …

A Novel Sialylation Pathway Mediated By Extracellular Vesicles In Aggressive Prostate Cancer, Camila A. Bach, Md Niamat Hossain, Ishan J. Chaudhari, Cecilia E. Verrillo, Nicole M.

Altered cell surface glycosylation is a hallmark of cancer; among aberrant glycan structures, hypersialylated proteins contribute to disease progression. The enzyme ST6 β-galactoside α2,6-sialyltransferase 1 (ST6GAL1) mediates α2,6-linked sialylation of N-glycosylated proteins and is upregulated in many cancers, including prostate cancer (PrCa). We propose that ST6GAL1 may be released by cancer cells in small extracellular vesicles (sEVs) in the PrCa tumor microenvironment to potentially modulate cell surface sialylation in recipient cells. We isolated sEVs from PrCa cells by density gradient separation and characterized them by nanoparticle tracking analysis using ZetaView and immunoblotting analysis. We identified ST6GAL1 in both its membrane-bound …

SKMC Student Presentations and Publications

Background: Differentiating acute kidney injury (AKI) from chronic kidney disease (CKD) in children remains a critical unmet need due to the limitations of current clinical and biochemical markers. Conventional ultrasound lacks the sensitivity to discern subtle parenchymal alterations. This study explores the application of ultrasound radiomics—a novel, non-invasive, and quantitative image analysis method—for distinguishing AKI from CKD in pediatric patients. Methods: In this retrospective cross-sectional pilot study, kidney ultrasound images were obtained from 31 pediatric subjects: 8 with oliguric AKI, 14 with CKD, and 9 healthy controls. Renal parenchyma was manually segmented, and 124 advanced texture features were extracted using …

Evaluating Dosimetric Outcomes In A Prostate Rapid Plan Model: A Comparison Of Prostate Treatment Plans With And Without Standardized Planning Structures, Erica Wartman

Masters Projects

Abstract

Knowledge-based planning (KBP) using RapidPlan (RP) has demonstrated the ability to produce high quality radiation therapy treatment plans while reducing time. This study evaluated whether the inclusion of department specific standardized planning structures, including rings and other optimization tools, improves plan quality when using a prostate and lymph node RP model, or if the model alone is sufficient to provide a quality plan without the use of these additional planning structures.

Ten previously treated Prostate+LN patients were replanned using the departmental RP model in Varian Eclipse treatment planning system.1 For each patient, two plans were created, one with standardized …

Jefferson Hospital Staff Papers and Presentations

BACKGROUND AND OBJECTIVE: NRG/RTOG 0521 randomized men with high-risk localized prostate cancer (PC) to androgen suppression (AS) and definitive radiotherapy (RT) ± docetaxel-based chemotherapy (CT). The overall survival (OS) benefit with CT initially reported was lost on longer follow-up. The Decipher genomic classifier (GC) measures multiple transcripts relevant to docetaxel action. Basal/luminal differentiation portends differential response to AS and CT for high-risk localized and metastatic hormone-sensitive PC. We validated the Decipher GC in pretreatment biopsy samples for risk stratification and examined basal-luminal subtyping to predict docetaxel response.

METHODS: Decipher GC scores and basal-luminal cellular subtypes were generated for specimens from …

It is known that β1 integrins and a downstream signaling molecule c-Src are upregulated in prostate cancer (PrCa) tissues, are co-expressed in circulating small extracellular vesicles (sEVs) and contribute to cancer progression. Here, we demonstrate that sEVs from PrCa patients show robust expression of both β1 integrins and c-Src. The impact of irradiation, a widely used therapy for the treatment of PrCa, on circulating sEVs is however not fully understood. We show that sEVs isolated from the plasma of transgenic adenocarcinoma of mouse prostate (TRAMP) mice, stimulate migration and anchorage-independent growth of recipient cancer cells, but sEVs are not active …

Characterization Of Lactobacilli-Containing Catheter Segments Developed By Using Selective Laser Sintered Mold., Caden Maners

Master of Engineering Theses

Catheter-associated urinary tract infections (CAUTIs) are a major healthcare burden with current prevention strategies offering limited success. This study presents a novel, self-coating biomaterial approach using a silicone-based bioink embedded with thermally sensitive probiotic strains (L. crispatus, L. rhamnosus, and L. reuteri). Catheter segments were fabricated via bio-injection molding using 3D-printed CAD molds. These Lactobacilli, selected for their probiotic and antimicrobial potential, serve as a non- antibiotic strategy to reduce infection risk. These segments were evaluated for mechanical strength (Shore A hardness), thermal stability (TGA/DSC), porosity and bacterial presence (SEM), biofilm formation (crystal-violet assay), as well as mass retention in …

Port Site Metastasis After Robotic Assisted Laparoscopic Radical Prostatectomy: Diagnosis Via Prostate-Specific Membrane Antigen (Psma)-Targeted 18f-Dcfpyl Pet/Ct, Joon Yau Leong, Maria D'Amico, Courtney Capella, Leonard Gomella, Joseph Izes

Department of Urology Faculty Papers

We present a case of port site metastasis (PSM) that was identified in an 82-year-old man with an elevated prostate-specific antigen (PSA) to 3.9 ng/mL, concerning for biochemical recurrence after robotic-assisted radical prostatectomy, adjuvant radiation, and six months of androgen deprivation therapy with an undetectable PSA post-treatment over 10 years ago. A 2.1 cm solitary tracer avid nodule on the right lateral abdominal wall with no other evidence of recurrence or metastatic disease was found on prostate-specific membrane antigen (PSMA)–targeted ¹⁸F-DCFPyL PET/CT scan. The patient underwent local excision of this metastatic lesion, and final pathology revealed metastatic prostatic adenocarcinoma.

Ultrasonographic Appearance Of Suspected Zinner Syndrome, Wen Hao Luo, Jared Garfinkle, Jack Hennen, Robert Martin, Kathleen Deiling

Rowan-Virtua Research Day

Zinner syndrome (ZS) is a rare congenital condition characterized by the triad of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. ZS is suspected to be caused by the malformation of the mesonephric duct during embryogenesis. The incomplete migration of the ureteric bud results in ipsilateral renal agenesis and ejaculatory duct obstruction. The remaining gonad develops with inadequate seminal fluid drainage, leading to the formation of seminal vesicle cysts. ZS is often asymptomatic, leading to challenges in diagnosis, particularly in adolescents. Symptoms can include pain, dysuria, pollakisuria, perineal pain, epididymitis, and pain after ejaculation. Imaging plays …

Assessing The Efficacy Of Prolonged Doxycycline Pep Use In High-Risk Populations For Sti Prevention, Lam Doan, Pearl Joslyn, Lizann Sung, Timothy Breiner, Sarah Marotta, Shikhar Rastogi

Rowan-Virtua Research Day

First recommended in October 2022, doxycycline post-exposure prophylaxis (DoxyPEP) has been increasingly used as a treatment for multiple sexually transmitted infections (STIs). To evaluate the efficacy of prolonged DoxyPEP use in high risk populations - men who have sex with men (MSM) and transgender women - for STIs, different sources addressing various aspects of DoxyPEP, its efficacy in STI prevention, and the potential consequences of its widespread use in terms of antimicrobial resistance were examined. Across 9 studies, DoxyPEP was found to decrease the incidence of bacterial STIs, specifically, syphilis, chlamydia, and gonorrhea with varying efficacy, especially for gonorrhea. Furthermore, …

Diallo, Christopher J. Smith, Marcio C. Moschovas, Iman Hajirasouliha, Andrew J. Hung, Srirama S. Venkataraman, Vipul Patel

Publications and Research

Preoperative identification of extracapsular extension (ECE) in prostate cancer (PCa) is crucial for effective treatment planning, as ECE presence significantly increases the risk of positive surgical margins and early biochemical recurrence following radical prostatectomy. AutoRadAI, an innovative artificial intelligence (AI) framework, was developed to address this clinical challenge while demonstrating broader potential for diverse medical imaging applications. The framework integrates T2-weighted MRI data with histopathology annotations, leveraging a dual convolutional neural network (multi-CNN) architecture. AutoRadAI comprises two key components: ProSliceFinder, which isolates prostate-relevant MRI slices, and ExCapNet, which evaluates ECE likelihood at the patient level. The system was trained and …

Kimmel Cancer Center Faculty Papers

Objective: The study aimed to prospectively evaluate the feasibility of diagnosing PCa using voided urine samples and by targeting the genomic VPAC (vasoactive intestinal peptide and pituitary adenylate cyclase-activating peptide) receptors in comparison with multiparametric magnetic resonance imaging (mp-MRI) in male patients (≥40 years of age) with lower urinary tract symptoms and having a serum PSA of >4 but < 15 ng/ml.

Patients and methods: Male patients attending urological services ≥40 years old, with lower urinary tract symptoms and serum PSA levels of >4 but < 15 ng/ml formed the study group. Voided urine samples were collected to target VPAC receptors on malignant cells. All patients underwent mp-MRI. A 12-core transrectal ultrasound-guided prostate biopsy was performed in all, and the results were compared for the diagnosis of PCa.

Results: A total of 61 patients with a median age of 65.33 ± 8.11 years and with a …

Reduction Of Prostate Cancer Risk: Role Of Frequent Ejaculation-Associated Mechanisms., Mohamed Hassan, Thomas W. Flanagan, Abdulaziz M. Eshaq, Osama K.

School of Medicine Faculty Publications

Simple Summary: There is considerable evidence to suggest that frequent ejaculation reduces the risk of prostate cancer. The more frequently ejaculation occurs without risky sexual behavior, the lower the risk of prostate cancer. The mechanisms regulating the reduction in PCa risk associated with frequent ejaculations are attributed to the suppression of the sympathetic nervous system, resulting in a relief of tension and a slowing of the division of prostate epithelial cells. It is suggested that ejaculation frequency affects gene expression in prostate tissue and subsequently influences the susceptibility of the tissue to tumor formation, leading to a reduction in the …

Black men suffer disproportionately from prostate cancer (PCa) compared to men of other races and ethnicities. Comparing the molecular landscape of PCa among Black and White patients has the potential to identify targets for development of new precision medicine interventions. Herein, we conducted transcriptomic analysis of prostate tumors and paired tumor-adjacent normals from self-reported Black and White PCa patients and estimated patient genetic ancestry. Clinical follow-up revealed increased biochemical recurrence (BCR) among Black patients compared to White patients with high-grade PCa. Transcriptomic analysis identified differential alternative RNA splicing events (ARSs) between Black and White PCa patients. Genes undergoing genetic ancestry-concordant …

Il-1Β In Neoplastic Disease And The Role Of Its Tumor-Derived Form In The Progression And Treatment Of Metastatic Prostate Cancer, Yetunde Oyende, Luke Taus, Alessandro Fatatis

Kimmel Cancer Center Faculty Papers

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders. However, this approach has consistently relied on the perceived need of interfering with IL-1β …
