The causes and consequences of abnormal biogenesis of extracellular vesicles (EVs) are not yet well understood in malignancies, including in breast cancers (BCs). Given the hormonal signaling dependence of estrogen receptor-positive (ER+) BC, we hypothesized that 17β-estradiol (estrogen) might influence EV production and microRNA (miRNA) loading. We report that physiological doses of 17β-estradiol promote EV secretion specifically from ER+ BC cells via inhibition of miR-149-5p, hindering its regulatory activity on SP1, a transcription factor that regulates the EV biogenesis factor nSMase2. Additionally, miR-149-5p downregulation promotes hnRNPA1 expression, responsible for the loading of let-7's miRNAs into EVs. In multiple patient cohorts, …

Outpatient Breast Cancer Screening Documentation, Christoffer A. Amdahl, Jeremy Smith

North Texas GME Research Forum 2023

Introduction: Over 264,000 cases of breast cancer are diagnosed annually within the United States, with 99% of them being in women. Regarding prevention of this terrible disease, early detection of such cancers through screening mammography has up to a 20% reduction in breast cancer mortality. Therefore, the USPSTF recommends screening of women who are 50-74 years of age via mammography at average risk of breast cancer every two years. The goal of this study was to measure, track, and increase compliance with these screening recommendations within the Medical City resident clinics.

Method: Family medicine residents working were presented with a …

Perspectives Of People With Cancer Or Hereditary Cancer Risk On The Use And Value Of Online Peer Support, Jill Holdren, Karl Surkan, Andrea Downing

Journal of Patient-Centered Research and Reviews

Purpose: People with cancer routinely seek information and support in peer groups online. While peer communities constitute a major component of the health care landscape, they exist in isolation from clinical and research institutions. This study aimed to explore how and why cancer patients utilize online peer support groups and how they might be improved.

Methods: A convenience sample of members of 6 closed Facebook cancer peer support groups (n = 291) participated in an online needs assessment survey. We further conducted semi-structured interviews with 14 members and 6 moderator-patients, hand-coding the free-text responses and interview transcripts.

The availability of high-fidelity animal models for oncology research has grown enormously in recent years, enabling preclinical studies relevant to prevention, diagnosis, and treatment of cancer to be undertaken. This has led to increased opportunities to conduct co-clinical trials, which are studies on patients that are carried out parallel to or sequentially with animal models of cancer that mirror the biology of the patients' tumors. Patient-derived xenografts (PDX) and genetically engineered mouse models (GEMM) are considered to be the models that best represent human disease and have high translational value. Notably, one element of co-clinical trials that still needs significant …

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer. Neoadjuvant systemic therapy (NAST) followed by surgery are currently standard of care for TNBC with 50-60% of patients achieving pathologic complete response (pCR). We investigated ability of deep learning (DL) on dynamic contrast enhanced (DCE) MRI and diffusion weighted imaging acquired early during NAST to predict TNBC patients' pCR status in the breast. During the development phase using the images of 130 TNBC patients, the DL model achieved areas under the receiver operating characteristic curves (AUCs) of 0.97 ± 0.04 and 0.82 ± 0.10 for the training and the …

The purpose of this study was to examine differences in health-related outcomes (anemia, neutropenia, and infection) and utilization of health care resources (inpatient, outpatient, and emergency visits) in BCS with and without diabetes.

Methods: In this retrospective cohort study, data were leveraged from the electronic health records of a large health network linked to the Indiana State Cancer Registry. BCS diagnosed between January 2007 and December 2017 and who had received chemotherapy were included. Multivariable logistic regression and generalized …

Patient And Clinician Characteristics That Predict Breast Cancer Screening Behavior In 40–49-Year-Old Women, Sarina Schrager, Claudia Evaristo, Terry Little, Lori Dubenske, Elizabeth S. Burnside

Journal of Patient-Centered Research and Reviews

Guidelines recommend that clinicians practice shared decision-making (SDM) with women in their 40s to discuss breast cancer screening. Traditionally, SDM includes discussion of values and preferences to help determine a decision that is congruent with what the patient desires. We analyzed 54 women’s breast cancer screening decisions after a SDM conversation with their clinician. We looked at both patient and clinician characteristics that predicted whether or not a woman would get a screening mammogram. Women with a family history of breast cancer or who had a previous abnormal mammogram had higher rates of screening. Screening rates also varied widely between …

Tumiel-Berhalter, Laura A. Brady, Alexandrea Bentham, Karen Vitale, Amanda Norton, Gary Noronha, Carlos Swanger

Journal of Patient-Centered Research and Reviews

Purpose: In the United States, cancer screening rates are often below national targets. This project implemented practice facilitation and academic detailing aimed at increasing breast, cervical, and colorectal cancer screening rates in safety-net primary care practices.

Methods: Three practice-based research networks across western and central New York State partnered to provide quality improvement strategies on breast, cervical, and colorectal cancer screening. Pre/postintervention screening rates for all participating practices were collected annually, as were means across all practices over 7 years. Simple ordinary least squares linear regression was used to calculate the trend for each cancer type and test for statistical …

The Molecular Mechanisms Linking Metabolic Syndrome To Endometrial And Breast Cancers, Andrada-Luciana Lazar, Romana Vulturar, Adriana Fodor, Olga Hilda Orasan, Camil-Horia Eusebiu Crișan, Cezar Login, Ioana Para, Vasile Negrean, Brandusa Tiperciuc, Angela Cozma

Journal of Mind and Medical Sciences

The metabolic syndrome represents a plethora of cardio-metabolic risk factors including obesity, arterial hypertension, atherogenic dyslipidemia, hyperglycemia, accompanied by pro-inflammatory and pro-thrombotic state. The metabolic syndrome is one of the key risk factors for certain types of cancer. Among these malignancies, breast cancer and endometrial neoplasms require special attention. Incriminated major causes for the development of breast and endometrial cancer in metabolic syndrome patients are: the pro-inflammatory status and related cytokines, adipokine imbalances, hyperestrogenism, growth factors, disturbances in cancer microenvironment, insulin resistance and hyperinsulinemia. The metabolic syndrome consists of molecular dysregulations that create a pro-oncogenic status. Our review aims at …

Phyllodes Tumor Containing Invasive Ductal Carcinoma: A Rare Case Description & Review Of Literature, Kathryn Eckert, John Ground, Alyssa Imperatore, Victoria Tiedemann, Linda Szczurek

Rowan-Virtua Research Day

Phyllodes tumors are uncommon, often benign, malignancies of the breast and account for approximately 0.5% of all breast malignancies. These tumors were first described in 1838 by Johannes Muller as cystosarcoma phyllodes and were later more aptly renamed phyllodes tumors (as they were neither cystic nor sarcomatous).(1) As a mixed connective tissue and epithelial tumor, these behave similar to benign fibroadenomas, though their growth is much more rapid and they tend to occur in older patients.(2) Hallmarked by their large size at presentation, these tumors average between 4 and 7 cm at the time of diagnosis. The only known risk …

Gina Capitano Ed.D.,R.T. (R)

Abstract

This research is a case study of a 34-year-old patient that presented with a right breast lump measuring 1.9cm found to have invasive mammary carcinoma. Diagnostic mammogram and ultrasound were followed by ultrasound guided breast biopsy to make the diagnosis.

Breast cancer is the leading cause of cancer-related death in women between the ages of 15-39 inthe United States. Annual mammograms are recommended to begin at age 40, therefore younger women often do not have mammograms or breast ultrasounds unless they have symptoms. As a result, younger …

This dissertation (a) provided an in depth literature review of methods to disrupt the BBB/BTB and improve therapeutic distribution to brain tumors, (b) evaluated the use of azacitidine as a single agent therapy for the treatment of brain metastasis of breast cancer and a potential molecular mechanism by which brain tropic cells are sensitized to hypomethylating agents, (c) determined the impact cannabidiol has on P-glycoprotein mediated efflux at the blood-brain barrier and its potential for use as a single agent treatment for metastatic brain tumors, (d) developed a preclinical radiation therapy protocol for use in small animals and in vitro …

Stat5a Regulation By Serine Phosphorylation In Breast Cancer, Alicia E. Woock

Theses and Dissertations

The neuroendocrine hormone prolactin (PRL) and its cognate receptor (PRLr) have been implicated in the pathogenesis of breast cancer. PRL signaling relies on activating kinases such as the tyrosine kinase Jak2 and serine/threonine kinases ERK1/2, NEK3, PI3K, and AKT. In the canonical pathway of PRL signaling, JAK2 phosphorylates the transcription factor STAT5a at tyrosine residue 694 (pY694-STAT5a), preceding STAT5a nuclear translocation and transcriptional activity. However, STAT5a exists with functional duality as a transcription factor, having both pro-differentiative and pro-proliferative target genes. Other STAT family members (STATs 1, 3, and 6) have been shown to have transcriptional activity in the un-tyrosine-phosphorylated …

Purpose: Breast cancer survivors are at increased risk of cancer recurrence, second malignancies, and other comorbid conditions. This study examined if use of a convenient, commercially available, $65 per month app that gives breast cancer survivors access to a health and wellness coach is more effective than a self-guided toolkit and one-time health education session at achieving the following goals: 1) improving adherence to a plant-based diet, 2) increasing physical activity, 3) assisting with weight loss and reduction in body mass index, 4) reducing elevated depression and fatigue scores, and 5) leading to sustained adherence to lifestyle and wellness plan …

Cole Relaxation Frequency As A Prognostic Parameter For Breast Cancer, William D. Gregory, Shahila Mehboob Christie, John Shell, Georges J. Nahhas, Maharaj Singh, Wendy Mikkelson

Journal of Patient-Centered Research and Reviews

We previously reported successful classification of breast cancer versus benign tissue using the Cole relaxation frequency measured on tissue excised during breast surgery as part of a study at two urban hospitals in the U.S. Midwest. Using that health system’s cancer registry, we have discovered retrospectively that outcomes for patients who participated in the initial study can be classified correctly in 3 well-differentiated categories: nonrecurrent (NR); recurrent with no metastasis (RNM); and recurrent with metastasis (RM). As Cole relaxation frequency increases, the classification moves from NR to RNM and finally to RM. Multivariate analysis showed a significant association of “time-cancer-free” …

A History Of #Bcsm And Insights For Patient-Centered Online Interaction And Engagement, Matthew S. Katz, Alicia C. Staley, Deanna J. Attai

Journal of Patient-Centered Research and Reviews

Purpose: Participation in cancer support groups can provide a sense of community and may better prepare patients for interactions with their health care team. Online interactions may overcome some barriers to in-person support group participation. #BCSM (breast cancer social media), the first cancer support community established on Twitter, was founded in 2011 by two breast cancer survivors. The aims of this study are to describe the growth and changes in this community and to discuss future directions and lessons that may apply to other online support communities.

Methods: Symplur Signals was used to obtain all #BCSM Twitter data from January …

Identification Of Microscopy Cell Images By Using Convolutional Neural Network Application, Ajis Norfatin Farisya

Student Works (2020-2029)

Breast cancer has been the major factor of cancer death and the second main cause of women’s deaths in the world. The false positive results of this cancer cell detection during the screening test leads to false treatment and emotional disturbance of the patients. Thus, breast cancer cell lines (MCF7) is used as the microscopy image samples together with the Human Bone Osteosarcoma Epithelial Cells (U2OS), and Human Hepatocyte as control to study the effectiveness of convolutional neural network (CNN) as a method of image recognition. The objectives of this study are to determine the ability of convolutional neural network …

Black Women Survive Breast Cancer With Community-Based Care, Shelley I. White-Means, Jill Dapremont, Barbara D. Davis, Tronlyn Thompson

Faculty Presentations

PURPOSE Community-based breast cancer support agencies who address non-medical, social determinants of health needs that serve as barriers to maximizing breast health outcomes may play a vital role in mitigating breast cancer mortality. They share a common emphasis on addressing social, economic, and psychological needs of breast cancer survivors and those at risk of breast cancer. This paper is third in a series of papers exploring why the rate of breast cancer mortality is two times higher for African American women than white women in Memphis. We sought insights from community-based breast cancer support agencies because they have a close-up …

From Bedside To Bench: Use Of Patient-Derived Xenograft Models To Develop Novel Therapeutic Strategies For Triple-Negative Breast Cancer, Tia H. Turner

Theses and Dissertations

Triple-negative breast cancer (TNBC) is a clinically aggressive disease that is associated with bleak outcomes due to its metastatic propensity, frequent failure to respond to chemotherapy, and lack of alternative treatment options. Despite decades of major translational research efforts, there has been very little success thus far in the development of effective targeted therapies for this disease. It is imperative to develop novel therapeutic strategies to improve patient outcomes, as well as minimize the toxicity associated with standard-of-care chemotherapeutics. Given that metastatic disease accounts for the vast majority of TNBC-related deaths, a better understanding of therapeutic responses within common sites …

The Role Of Syndecan-1 And Extracellular Vesicles In Breast Cancer Brain Metastasis, Megan R. Sayyad

Theses and Dissertations

Breast cancer metastasizes to the brain in 15-30% of all breast cancer cases, and metastasis is the predominant cause of breast cancer-related deaths. Patients with HER2-enriched and triple-negative breast cancers (TNBCs) are more likely to develop brain metastases. While targeted therapies exist for HER2-enriched breast cancers, there are no effective treatments for TNBCs. Thus, a greater understanding of how these cancers spread to the brain is critical. In order to spread to the brain, disseminated breast cancer cells must overcome 2 major steps—crossing the blood-brain barrier (BBB) and survival and successful colonization of the distinctive and mostly cellular brain environment. …

The E2f4 Prognostic Signature Predicts Pathological Response To Neoadjuvant Chemotherapy In Breast Cancer Patients, Kenneth M. K. Mark, Frederick S. Varn, Matthew H. Ung, Feng Qian, Chao Cheng

Dartmouth Scholarship

Neoadjuvant chemotherapy is a key component of breast cancer treatment regimens and pathologic complete response to this therapy varies among patients. This is presumably due to differences in the molecular mechanisms that underlie each tumor’s disease pathology. Developing genomic clinical assays that accurately categorize responders from non-responders can provide patients with the most effective therapy for their individual disease. We applied our previously developed E2F4 genomic signature to predict neoadjuvant chemotherapy response in breast cancer. E2F4 individual regulatory activity scores were calculated for 1129 patient samples across 5 independent breast cancer neoadjuvant chemotherapy datasets. Accuracy of the E2F4 signature in …

Characterization Of Murine Breast Cancer Cell Lines For Anti-Cancer Vaccine, Haven N. Frazier

Biological Sciences Undergraduate Honors Theses

Breast cancer is the most commonly diagnosed cancer in women and the second leading cause of cancer death among women in the United States (1). While treatments involving radiation and chemotherapy currently exist, disease must be detected early in order for the treatments to be somewhat effective, and there is no effective treatment after metastasis occurs (2). Additionally, current therapies do not mitigate tumor immunosuppression. Decreasing the tumor-associated immunosuppressive conditions while activating antitumor immunity could prevent recurrence and metastasis, possibly leading to an effective treatment for cancer (3). Tumor cell vaccines could possibly address this issue and have become a …

Cis-Eqtl-Based Trans-Ethnic Meta-Analysis Reveals Novel Genes Associated With Breast Cancer Risk, Joshua Hoffman, Rebecca Graff, Nima Emami, Caroline Tai, Michael Passarelli

Dartmouth Scholarship

Breast cancer is the most common solid organ malignancy and the most frequent cause of cancer death among women worldwide. Previous research has yielded insights into its genetic etiology, but there remains a gap in the understanding of genetic factors that contribute to risk, and particularly in the biological mechanisms by which genetic variation modulates risk. The National Cancer Institute's "Up for a Challenge" (U4C) competition provided an opportunity to further elucidate the genetic basis of the disease. Our group leveraged the seven datasets made available by the U4C organizers and data from the publicly available UK Biobank cohort to …

Group Medical Visits To Provide Gynecologic Care For Women Affected By Breast Cancer, Sally R. Greenwald, Sarah Watson, Mindy Goldman, Tami S. Rowen

Journal of Patient-Centered Research and Reviews

Purpose

Women with breast cancer have complex and unique gynecologic needs that are challenging to effectively and comprehensively meet in a traditional gynecology visit format. Group medical visits are an effective and well-received model of care in other disease settings and can provide comprehensive health education as an adjunct to one-on-one evaluation and treatment. There are limited data regarding the use of this type of health care delivery in providing gynecology-focused care to women affected by breast cancer.

Methods

A group medical visit model was created for gynecology providers to see new breast cancer patient consults. From May 2012 to …

Steroid Hormone Receptors As Prognostic Markers In Breast Cancer, Maggie C. Louie, Mary B. Sevigny

Faculty Publications & Research of the TUC College of Pharmacy

Despite the existence of many promising anti-cancer therapies, not all breast cancers are equally treatable, due partly to the fact that focus has been primarily on a few select breast cancer biomarkers- notably ERα, PR and HER2. In cases like triple negative breast cancer (ERα-, PR-, and HER2-), there is a complete lack of available biomarkers for prognosis and therapeutic purposes. The goal of this review is to determine if other steroid receptors, like ERβ and AR, could play a prognostic and/or therapeutic role. Data from various in vitro, in vivo, and clinical breast cancer studies were examined …

Determining The Incidence And Factors Of Cardiotoxicity In Breast Cancer Patients Treated With Anthracycline And/Or Trastuzumab-Containing Regimen At Aurora Health Care, Stephanie Ghojallu, Matthew Rappelt, Han-Yang Chen, Ruth Perez, Lydia Garlie, Geoffrey Riddell, Yingying Gu, Jun Zhang, Rubina Qamar, Bijoy K. Khandheria, Arshad Jahangir, Yang Shi

Journal of Patient-Centered Research and Reviews

Background: Anthracycline and trastuzumab are common breast cancer treatments. While improving survival, they elevate risk of congestive heart failure. The incidence of cardiotoxicity (CTx) with these therapies varies in the literature from 10% to 59%, higher than those reported in clinical trials (4%–10%) that excluded patients with preexisting cardiovascular comorbidities. Studies have failed to establish consensus on the risk factors for CTx associated with these therapies.

Purpose: We aim to determine the incidence and risk factors of CTx in breast cancer patients treated with anthracycline and/or trastuzumab at Aurora Health Care.

Methods: A retrospective review of patients with breast cancer …
