Menoufia Medical Journal

Objective The aim of this study was to estimate the expression of androgen receptors (ARs) in patients with estrogen receptor (ER)-negative breast cancer. Background Growth of breast cancer is hormone dependent. Estrogen and progesterone play a fundamental role in the pathogenesis and treatment of patients with ER-positive breast cancer and those with progesterone receptor-positive breast cancer. Patients who lack the expression of these receptors receive no benefit from hormonal treatment and are considered to have a poor prognosis. AR is a member of nuclear steroid receptors with ambiguous role in patients with breast cancer. There is growing evidence about its …

Nanoparticle-Mediated Therapeutic Agent Delivery For Treating Metastatic Breast Cancer—Challenges And Opportunities, Yunfei Li, Brock Humphries, Chengfeng Yang, Zhishan Wang

Toxicology and Cancer Biology Faculty Publications

Breast cancer (BC) is the second leading cause of cancer-related death in American women and more than 90% of BC-related death is caused by metastatic BC (MBC). This review stresses the limited success of traditional therapies as well as the use of nanomedicine for treating MBC. Understanding the biological barriers of MBC that nanoparticle in vivo trafficking must overcome could provide valuable new insights for translating nanomedicine from the bench side to the bedside. A view about nanomedicine applied in BC therapy has been summarized with their present status, which is gaining attention in the clinically-applied landscape. The progressions of …

Trends In Reconstructive Surgery Following Mastectomy At A Single Institution Between 2011 And 2015, Jessica Barton, Jaclyn Malat, Sergio Perez, Michael T. Brown

Research Day

Current trends show that same-day breast reconstruction after oncologic breast surgery is increasing. Data regarding the factors contributing to this increase in oncoplastic surgery is lacking. We examine the timing and type of reconstructive surgery following mastectomy at Reading Hospital between 2011 and 2015. We hypothesized that the majority of women would choose immediate reconstruction rather than delayed reconstruction following mastectomy and that the number of reconstructive surgeries would increase from 2011 to 2015 correlating with the increase in availability and popularity of oncoplastic breast procedures. This retrospective study looked at a total of 579 patients, 129 of which underwent …

Effect Of Exercise Interventions On Fatigue For Breast Cancer: A Systematic Review And Meta-Analysis, Julien Succar

Biomedical Sciences ETDs

We conducted a systematic review and meta-analysis on the effect of different exercise interventions on fatigue in patients with breast cancer undergoing active therapy. We found that exercise generally improves fatigue outcomes at 12 weeks after initiation of the exercise intervention. Aerobic exercise intervention improved fatigue, but anaerobic and combination regimens did not show improvement compared to controls. Moreover, no exercise intensity was found to be superior compared to controls. Our findings revealed that there is a need for standardization of exercise regimens in studies in order to identify the most effective exercise regimen.

Investigating Invasion In Ductal Carcinoma In Situ With Topographical Single Cell Genome Sequencing, Anna Casasent, Anna Casasent

Dissertations & Theses (Open Access)

Synchronous Ductal Carcinoma in situ (DCIS-IDC) is an early stage breast cancer invasion in which it is possible to delineate genomic evolution during invasion because of the presence of both in situ and invasive regions within the same sample. While laser capture microdissection studies of DCIS-IDC examined the relationship between the paired in situ (DCIS) and invasive (IDC) regions, these studies were either confounded by bulk tissue or limited to a small set of genes or markers. To overcome these challenges, we developed Topographic Single Cell Sequencing (TSCS), which combines laser-catapulting with single cell DNA sequencing to measure genomic copy …

Methods. Symptoms were identified in breast cancer patients (N=219) before the start of CTX (baseline), 30 days after the last CTX, and 1-year after the first CTX. Hospital Anxiety and Depression Scale and Symptom Experience Scale …

Genomic Evolution Of Chemoresistance In Triple-Negative Breast Cancer Delineated By Single Cell Sequencing, Charissa Kim

Dissertations & Theses (Open Access)

Triple-negative breast cancer (TNBC) is an aggressive subtype that displays extensive intratumor heterogeneity and frequently (46%) develops resistance to neoadjuvant chemotherapy (NAC). Currently, the genomic basis of chemoresistance remains poorly understood. An important question is whether resistance to chemotherapy is driven by the selection of rare pre-existing subclones with genomic mutations and transcriptional programs that confer resistance to chemotherapy (adaptive resistance) or by the spontaneous induction of new mutations and expression changes that confer a resistant phenotype (acquired resistance). To investigate this question we applied single cell DNA and RNA sequencing methods and deep-exome sequencing to longitudinal time-point samples collected …

Oncoplastic Surgery: Is It Time To Change? From Innovation To Adoption Using Mentorship Program, Eman Khayat

Electronic Thesis and Dissertation Repository

Oncoplastic surgery is considered the standard of care for breast cancer therapy in numerous Western World countries, particularly in Europe. Despite the advancement of knowledge, Canada still lags in adoption of oncoplasty into the standard surgical practice. In our study, a mentorship program was used to introduce oncoplastic surgery to practicing breast surgeons at LHSC. The change in perception and adoption of oncoplastic surgery were evaluated using semi-structured interviews, before and after the intervention, by qualitative thematic analysis method. Mentorship program was validated as a superior method of learning new surgical techniques by practicing surgeons, demonstrating acceptance of different levels …

Loss Of Inter-Cellular Cooperation By Complete Epithelial-Mesenchymal Transition Supports Favorable Outcomes In Basal Breast Cancer Patients., Anne Grosse-Wilde, Rolf E Kuestner, Stephanie M Skelton, Ellie Macintosh, Aymeric Fouquier D'Hérouël, Gökhan Ertaylan, Antonio Del Sol, Alexander Skupin, Sui Huang

Articles, Abstracts, and Reports

According to the sequential metastasis model, aggressive mesenchymal (M) metastasis-initiating cells (MICs) are generated by an epithelial-mesenchymal transition (EMT) which eventually is reversed by a mesenchymal-epithelial transition (MET) and outgrowth of life-threatening epithelial (E) macrometastases. Paradoxically, in breast cancer M signatures are linked with more favorable outcomes than E signatures, and M cells are often dispensable for metastasis in mouse models. Here we present evidence at the cellular and patient level for the cooperation metastasis model, according to which E cells are MICs, while M cells merely support E cell persistence through cooperation. We tracked the fates of co-cultured E …

Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi

LSU Master's Theses

Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol) …

Predictive Significance Of Stromal-Associated Lymphocytes In Response To Neoadjuvant Chemotherapy In Breast Cancer, Abeer H. Anter, Afaf T. Ibrahiem, Hala A. Mouhamed

Menoufia Medical Journal

Objective In this work, we aimed to assess whether the high stromal-associated lymphocytes and their subtypes in pretreatment core biopsies from patients with invasive breast carcinoma have a predictive role in pathologic response to neoadjuvant chemotherapy (NACT). Background Tumor-infiltrating lymphocytes including stromal-associated lymphocytes in breast cancer are considered a form of the host immune response to malignancy. Several studies suggested that tumor-infiltrating lymphocytes could predict better response to NACT, but their roles in predicting complete pathologic response (pCR) rate after NACT still needs further evaluation. Patients and methods Stromal-associated lymphocytes were evaluated in 100 pretreatment core biopsies from primary breast …

Department of Cancer Biology Faculty Papers

Background: Genetic classification of breast cancer based on the coding mRNA suggests the evolution of distinct subtypes. Whether the non-coding genome is altered concordantly with the coding genome and the mechanism by which the cell cycle directly controls the non-coding genome is poorly understood.

Methods: Herein, the miRNA signature maintained by endogenous cyclin D1 in human breast cancer cells was defined. In order to determine the clinical significance of the cyclin D1-mediated miRNA signature, we defined a miRNA expression superset from 459 breast cancer samples. We compared the coding and non-coding genome of breast cancer subtypes.

Results: Hierarchical clustering of …

Morgan, Changwon Yoo, Alok Deoraj, Sandhya Roy, Vijay Kumar Yadav, Mohannad Garoub, Hamza Assaggaf, Mayur Doke

Alok Deoraj

We present a combined environmental epidemiologic, genomic, and bioinformatics approach to identify: exposure of environmental chemicals with estrogenic activity; epidemiologic association between endocrine disrupting chemical (EDC) and health effects, such as, breast cancer or endometriosis; and gene-EDC interactions and disease associations. Human exposure measurement and modeling confirmed estrogenic activity of three selected class of environmental chemicals, polychlorinated biphenyls (PCBs), bisphenols (BPs), and phthalates. Meta-analysis showed that PCBs exposure, not Bisphenol A (BPA) and phthalates, increased the summary odds ratio for breast cancer and endometriosis. Bioinformatics analysis of gene-EDC interactions and disease associations identified several hundred genes that were altered by …

A Plasma Telomeric Cell-Free Dna Level In Unaffected Women With Brca1 Or/And Brca2 Mutations: A Pilot Study, Shatovisha Dey, Natascia Marino, Kanokwan Bishop, Paige N. Dahlgren, Aditi Shendre, Anna Maria Storniolo, Chunyan He, Hiromi Tanaka

Internal Medicine Faculty Publications

Plasma cell-free DNA (cfDNA) is a small DNA fragment circulating in the bloodstream originating from both non-tumor- and tumor-derived cells. A previous study showed that a plasma telomeric cfDNA level decreases in sporadic breast cancer patients compared to controls. Tumor suppressor gene products including BRCA1 and BRCA2 (BRCA1&2) play an important role in telomere maintenance. In this study, we hypothesized that the plasma telomeric cfDNA level is associated with the mutation status of BRCA1&2 genes. To test this hypothesis, we performed plasma telomeric cfDNA quantitative PCR (qPCR)-based assays to compare 28 women carriers of the BRCA1&2 mutation with age-matched controls …
