The Path Forward For T Cell Engagers In Patients With Prostate Cancer, Sumit K. Subudhi, Bilal A. Siddiqui, Kevin K. Zarrabi, William K. Kelly, Charles G. Drake

Department of Medical Oncology Faculty Papers

T cell engagers (TCEs) recruit T cells to the tumor microenvironment (TME) to induce antitumor immune responses. TCEs have demonstrated promising clinical responses in patients with metastatic castration-resistant prostate cancer and have advanced into phase 3 clinical trials. Here we provide an overview of the mechanisms of action of TCEs, including both CD3-targeted and CD28-targeted agents, and review the clinical development of these agents for prostate cancer. We propose a path forward for TCEs in prostate cancer, in which innovative clinical trials will facilitate a biological understanding of mechanisms of efficacy and toxicity to inform: (1) development of predictive biomarkers …

PURPOSE: Clinical risk grouping based on PSA, tumor grade, and disease extent guides treatment intensity for localized prostate cancer. However, many patients with intermediate- or high-risk disease treated with external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT) still develop biochemical recurrence (BCR). Early identification of patients at high risk for BCR could enable personalized treatment strategies.

EXPERIMENTAL DESIGN: We prospectively enrolled 29 patients with intermediate- or high-risk prostate cancer undergoing EBRT and ADT. Pretreatment biopsies (n = 60) underwent whole-transcriptome microarray and whole-exome sequencing. Patients received multiparametric MRI at baseline and 6 months after treatment, with a median follow-up …

Kimmel Cancer Center Faculty Papers

PURPOSE: Targeted therapies for metastatic prostate cancer are limited, highlighting the need for novel drug targets and mechanisms of action (MoA). Human kallikrein 2 (KLK2) is a prostate-specific antigen expressed across the prostate cancer disease continuum. However, it was not recognized as a therapeutic target for prostate cancer in the past due to limited evidence of its cell surface expression. In this study, we systematically characterized KLK2 expression in prostate cancer, confirmed its cell surface expression, and demonstrated the preclinical efficacy of three KLK2-targeting therapeutics with distinct MoA.

EXPERIMENTAL DESIGN: The KLK2 expression profile in different stages of prostate cancer …

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 …

Small cell bladder cancer (SCBC) is a rare and aggressive disease, often treated with platinum/etoposide-based chemotherapy. Key molecular drivers include the inactivation of onco-suppressor genes (TP53, RB1) and amplifications in proto-oncogenes (MYC). We report a patient with SCBC who achieved an objective and prolonged response to lurbinectedin, which has been approved for metastatic small cell lung cancer, after developing disease progression on cisplatin/etoposide and nivolumab/ipilimumab. A genomic analysis of a metastatic biopsy prior to lurbinectedin initiation revealed a TP53 mutation and amplification of the cell cycle regulators E2F3 and MYCL. A repeat biopsy following …

We describe a strategy that combines histologic and molecular mapping that permits interrogation of the chronology of changes associated with cancer development on a whole-organ scale. Using this approach, we present the sequence of alterations around RB1 in the development of bladder cancer. We show that RB1 is not involved in initial expansion of the preneoplastic clone. Instead, we found a set of contiguous genes that we term "forerunner" genes whose silencing is associated with the development of plaque-like field effects initiating carcinogenesis. Specifically, we identified five candidate forerunner genes (ITM2B, LPAR6, MLNR, CAB39L, and ARL11) mapping near RB1. Two …

Colon Cancer Metastasis To Spermatic Cord Presenting As An Inguinal Hernia, Jessica G. Laenger, Eamon Ff Rooney, Patrick F. Dial, Candie T. Le, Sanda A. Tan

HCA Healthcare Journal of Medicine

Introduction

Inguinal hernias are very common. Their pathology and treatment are typically strait forward. Metastatic cancer can sometimes present as an inguinal hernia, but this presentation is often local metastasis.

Case Presentation

Herein we describe the case of a 68-year-old man who presented with a 2-month history of an inguinal hernia. Intraoperatively, the hernia sac was found to contain a mass attached to the spermatic cord, which was later determined to be a metastatic lesion from a locally advanced proximal transverse colon adenocarcinoma.

Conclusion

A spermatic cord mass can be a rare presentation of colon cancer metastasis. Colon cancer should …

Radio-Histopathological Presentation And Multidisciplinary Treatment Of Adolescent Paratesticular Rhabdomyosarcoma: A Case Report, Troy Nguyen, Joseph Hatem, Abhijit Datir, Joel Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Paratesticular rhabdomyosarcoma (PRMS) is a rare condition predominantly affecting the pediatric and adolescent population. In this case report, we discuss a 17-year-old male with a slow-growing, painless scrotal mass, ultimately diagnosed as embryonal PRMS — the most common and favorable rhabdomyosarcoma subtype. The report underscores the typical clinico-radiological presentation of PRMS and the pivotal part of histopathological evaluation in establishing a definitive diagnosis. Multidisciplinary intervention including surgery and chemoradiotherapy resulted in total remission. Therefore, this report underlines the significance of prompt diagnosis and comprehensive management in ensuring a favorable prognosis of PRMS.

Urinary tract infections (UTIs) are one of the most common infectious clinical entities in both community and hospital settings. They have a broad range of clinical severity yet inflict large epidemiological burden of morbidity and mortality on patients and the healthcare system with billions of dollars in cost of treatment. Understanding what methods are optimal for diagnosing UTIs are critical to mitigate the marked impact and cost of these infections.

Chapter 1 and 2 in this work surveys the broad array of diagnostic modalities for UTIs and highlights their advantages and limitations in the context of the current standard of …


Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker May 2023

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (RCAP) and length (LCAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Switch-Like Behavior Of Lysosomes And Vcp Supports Spermatocyte Health And Development In Drosophila, Tyler James Butsch Apr 2023

Switch-Like Behavior Of Lysosomes And Vcp Supports Spermatocyte Health And Development In Drosophila, Tyler James Butsch

LSU Doctoral Dissertations

Changes to societal norms, such as the educational, marital, and child-bearing expectations have coincided with significant increases in infertility worldwide. Surprisingly, male infertility is responsible for approximately half of all infertility cases worldwide. Thus, a better understanding of sperm development, and how it is affected by age, may permit the design and application of therapeutics to treat various cases male infertility. Here, I have found that lysosomes acidify as germ cells enter the spermatocyte stage. Once active, lysosomes turn over E-cadherin, and likely other proteins, to support plasma membrane stability. Notably, aging negatively impacts lysosome acidification, which can be reversed …

Deficiency of MTAP (MTAPdef) mainly occurs because of homozygous loss of chromosome 9p21, which is the most common copy-number loss in metastatic urothelial cancer (mUC). We characterized the clinical and genomic features of MTAPdef mUC in 193 patients treated at MD Anderson Cancer Center (MDACC) and 298 patients from the phase 2 IMvigor210 trial, which investigated atezolizumab in cisplatin-ineligible and platinum-refractory disease. In the MDACC cohort, visceral metastases were significantly more common for MTAPdef (n = 48) than for MTAP-proficient (MTAPprof; n = 145) patients (75% vs 55.2%; p = 0.02). MTAPdef was associated with poor prognosis (median overall …

Background: Studies showed that folate and related single nucleotide polymorphisms (SNPs) could predict prostate cancer (PCa) risk. However, little is known about the interactions of folate-related SNPs associated with PCa aggressiveness. The study’s objective is to evaluate SNP–SNP interactions among the DHFR 19-bp polymorphism and 10 SNPs in folate metabolism and the one-carbon metabolism pathway associated with PCa aggressiveness. Methods: We evaluated 1294 PCa patients, including 690 European Americans (EAs) and 604 African Americans (AAs). Both individual SNP effects and pairwise SNP–SNP interactions were analyzed. Results: None of the 11 individual polymorphisms were significant for EAs and AAs. Three SNP–SNP …

Faculty, Staff and Student Publications

The term "cistrome" refers to the genome-wide location of regulatory elements associated with transcription factor binding-sites. The cistrome of key regulatory factors in prostate cancer etiology are substantially reprogrammed and altered during prostatic transformation and disease progression. For instance, the cistrome of the androgen receptor (AR), a ligand-inducible transcription factor central in normal prostate epithelium biology, is directly impacted and substantially reprogrammed during malignant transformation. Accumulating evidence demonstrates that additional transcription factors that are frequently mutated, or aberrantly expressed in prostate cancer, such as the pioneer transcription factors Forkhead Box A1 (FOXA1), the homeobox protein HOXB13, and the GATA binding …


The Efficacy Of Aquablation In The Treatment Of Large Volume Benign Prostatic Hypertrophy, Jessica Greenwood Jan 2020

The Efficacy Of Aquablation In The Treatment Of Large Volume Benign Prostatic Hypertrophy, Jessica Greenwood

Capstone Showcase

Introduction:

Benign Prostatic Hypertrophy (BPH) is a condition affecting adult males causing symptoms including urinary frequency, incontinence, and urinary retention. While first line treatment methods include lifestyle modifications and pharmacologic therapies, many patients elect for surgical procedures for symptomatic relief. In patients with extremely large volume prostates the surgical method most commonly used has been an open prostatectomy, which is associated with both long-term efficacy and more surgical complications than minimally invasive techniques. Therefore, this review analyzes Aquablation (I) for symptom management (O) in patients diagnosed with BPH (P) compared to open prostatectomy (C).

Methods:

A literature search was conducted …


Chemical Composition And Behavioural Responses Of Male And Female Bactrocera Dorsalis To Their Volatile Emissions, Fikira Kimbokota Dec 2019

Chemical Composition And Behavioural Responses Of Male And Female Bactrocera Dorsalis To Their Volatile Emissions, Fikira Kimbokota

Journal of Humanities and Social Sciences

Bactrocera dorsalis, (Tephritidae) presented a grave threat to a broad range of fruit and vegetables in the tropics, including Tanzania. Bactrocera dorsalis is among the most destructive tephritid fruit fly, causing devastating loss of fruits especially mango. Insects use olfactory cues to locate hosts, oviposition sites and mating, in which pheromones are believed to be a strong cue used by insect to locate their mates. However, due to their high ability to adapt and occupy different ecological niches into various agroecological zones, there is a need to evaluate pheromonal composition from time to time to improve their control strategies. Therefore, …


The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller May 2019

The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller

Theses & Dissertations

Prostate cancer is the second leading cause of cancer-related deaths in U.S. men, primarily due to the development of castration-resistant (CR) prostate cancer (PCa), of which there are no effective treatment options. Reactive oxygen species (ROS) plays a critical role in prostate carcinogenesis, including the progression of the CR PCa phenotype. ROS regulates both cell proliferation and apoptosis; a moderate increase in ROS can promote proliferation; however, a substantial rise in ROS levels will result in apoptosis. Oxidase p66Shc is elevated in clinical PCa cells and has been associated with a metastatic phenotype of CR PCa cells, promoting PCa cell …

Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli Jan 2019

Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli

Physician Assistant Scholarly Project Posters

Clinical varicoceles are the most frequent physical finding associated with infertile men and impaired semen parameters. There is evidence that suggests varicocele repair improves semen parameter and increases the chances of natural pregnancy. Today, varicocele repair is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in Vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In this literature review, data examining whether varicocelectomy before ART leads to improved pregnancy outcomes is reviewed. Current data suggest that there is a significant clinical benefit when correcting a varicocele in oligospermic men before IVF/ICSI. Similarly, men with non-obstructive azoospermia also …

Outcomes Of Genetic Testing In A Genitourinary Genetics Clinic, Annelise Pace

Dissertations and Theses (Open Access)

Several known hereditary cancer syndromes confer an increased risk for genitourinary (GU)related malignancies. Various guidelines indicate when to refer patients to genetic counseling for GU-related hereditary cancer syndromes but there is limited research on the clinical picture of these patients, including their cancerous and non-cancerous features, the genetic testing strategy for this population, and the probability of having a positive germline mutation if testing is performed. The purpose of this study is to determine the most common indications for ordering genetic testing in a GU Genetics Clinic and evaluate whether there is a relationship between the indication for genetic testing …

Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines …

Research outputs 2014 to 2021

Objectives

To explore if duration of previous exposure to androgen deprivation therapy (ADT) in men with prostate cancer (PCa) undertaking a year-long exercise programme moderates the exercise response with regard to body composition and muscle performance, and also to explore the moderator effects of baseline testosterone, time since ADT, and baseline value of the outcome.

Patients and Methods

In a multicentre randomized controlled trial, 100 men who had previously undergone either 6 months (short-term) or 18 months (long-term) of ADT in combination with radiotherapy, as part of the TROG 03.04 RADAR trial, were randomized to 6 months supervised exercise, followed …
