Psychological Respect For Patients With Breast Cancer Using Radial Incision Which Gives Better Cosmetic Outcome After Conservative Breast Surgery, Adel K. Barsoum, Hytham R. Yassin

Journal of Medicine in Scientific Research

Background Breast cancer is considered as one of the most common cancers affecting women, and remains one of the world's biggest killers. Once diagnosed as a breast cancer patient, a woman can be exposed to psychological trauma that is manifested as stress, anxiety, and even depression. Since surgery is the most important part of breast cancer management protocol, the first time a woman looks to her body after surgery can be harmful. Despite this gloomy picture, there have been some dramatic modifications recently in the treatment of breast cancer, especially in early detected tumors. One of them is the clear …

Background: Cytokines are being explored as a therapeutic strategy to modulate the tumor microenvironment and facilitate immunotherapy benefit in breast cancer. Here, we investigate a locoregional therapeutic approach whereby cytokines (IRX-2) are administered into the subcutaneous peri-areolar tissue (in an anatomic distribution similar to sentinel lymph node mapping) to facilitate immune cell recruitment/activation within the draining lymph nodes and tumor in ESBC. IRX-2 is derived from ex vivo phytohemagglutinin-stimulated lymphocytes and contains multiple cytokines including IL-1β, IL-2, TNF-α, IFN-γ, IL-6, IL-8, and GM-CSF, with stable concentrations from lot to lot. Preclinically, IRX-2 activates T-cells and natural killer (NK) cells, facilitates …

BRD4 assembles transcriptional machinery at gene super-enhancer regions and governs the expression of genes that are critical for cancer progression. However, it remains unclear whether BRD4-mediated gene transcription is required for tumor cells to develop drug resistance. Our data show that prolonged treatment of luminal breast cancer cells with AKT inhibitors induces FOXO3a dephosphorylation, nuclear translocation, and disrupts its association with SirT6, eventually leading to FOXO3a acetylation as well as BRD4 recognition. Acetylated FOXO3a recognizes the BD2 domain of BRD4, recruits the BRD4/RNAPII complex to the CDK6 gene promoter, and induces its transcription. Pharmacological inhibition of either BRD4/FOXO3a association or …

Society for Immunotherapy of Cancer 2018 Annual Meeting Posters

Background: The IRX-2 biologic is a subcutaneous injectable immunotherapy composed of IL-2 and other cytokines derived from stimulated lymphocytes. Preclinically, IRX-2 activates T cells, natural killer cells, macrophages, and dendritic cells, and facilitates maturation of antigen-presenting cells.Tumor-infiltrating lymphocytes (TILs) are associated with improved outcomes in many cancers including early stage breast cancer (ESBC) and head and neck squamous cell carcinoma (HNSCC). We report data on TIL recruitment associated with pre-operative IRX-2 in a phase Ib ESBC trial, as well as phase Ib and IIa HNSCC trials.

Methods: The pre-operative IRX-2 regimen was evaluated in both ESBC and HNSCC trials for …

Epidemiology Of Moderate Alcohol Consumption And Breast Cancer: Association Or Causation?, Samir Zakhari, Jan B. Hoek

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Epidemiological studies have been used to show associations between modifiable lifestyle habits and the incidence of breast cancer. Among such factors, a history of alcohol use has been reported in multiple studies and meta-analyses over the past decades. However, associative epidemiological studies that were interpreted as evidence that even moderate alcohol consumption increases breast cancer incidence have been controversial. In this review, we consider the literature on the relationship between moderate or heavy alcohol use, both in possible biological mechanisms and in variations in susceptibility due to genetic or epigenetic factors. We argue that there is a need to incorporate …

A Surprising Incidence Of Mammary Duct Ectasia In Egyptian Female Individuals: A 20-Year Experience, Adel K. Barsoum

Journal of Medicine in Scientific Research

The vast majority of breast pathology is benign. Much attention is given to malignant lesions because breast cancer is the most common malignancy in women. Duct ectasia is one of the benign breast diseases; Haagenson was the first to use the term. It is a widening of the ducts of the breast, a condition that occurs most frequently in women in their fourth and fifth decade of life. American Cancer Society states that mammary duct ectasia does not increase the risk for developing breast cancer, as duct ectasia is considered a nonproliferative disease (cells that have changed but are not …

Symptom Clusters And Quality Of Life Trajectories In Breast Cancer Patients Before And After Chemotherapy, Gaurav Kumar

Capstone Experience

Context. Breast cancer patients experience multiple concurrent symptoms before and after chemotherapy (CTX). Physical and psychological symptoms may persist after treatment and reduce the quality of life (QOL) of survivors.

Objectives. Identify differences in prevalence and severity of symptoms at three times within 1- year of starting CTX; and identify symptom cluster and QOL trajectories over these times in breast cancer patients.

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 …

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 …

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 …

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 …

Hyperspectral Imaging And K-Means Classification For Histologic Evaluation Of Ductal Carcinoma In Situ, Yasser Khouj, Jeremy Dawson, James Coad, Linda Vona-Davis

Faculty & Staff Scholarship

Hyperspectral imaging (HSI) is a non-invasive optical imaging modality that shows the potential to aid pathologists in breast cancer diagnoses cases. In this study, breast cancer tissues from different patients were imaged by a hyperspectral system to detect spectral differences between normal and breast cancer tissues. Tissue samples mounted on slides were identified from 10 different patients. Samples from each patient included both normal and ductal carcinoma tissue, both stained with hematoxylin and eosin stain and unstained. Slides were imaged using a snapshot HSI system, and the spec- tral reflectance differences were evaluated. Analysis of the spectral reflectance values indicated …

Tumor Mutational Burden Is A Determinant Of Immune-Mediated Survival In Breast Cancer., Alexandra Thomas, Eric D Routh, Ashok Pullikuth, Guangxu Jin, Jing Su, Jeff W Chou, Katherine A Hoadley, Cristin Print, Nick Knowlton, Michael A Black, Sandra Demaria, Ena Wang, Davide Bedognetti, Wendell D Jones, Gaurav A Mehta, Michael L Gatza, Charles M Perou, David B Page, Pierre Triozzi, Lance D Miller

Articles, Abstracts, and Reports

Mounting evidence supports a role for the immune system in breast cancer outcomes. The ability to distinguish highly immunogenic tumors susceptible to anti-tumor immunity from weakly immunogenic or inherently immune-resistant tumors would guide development of therapeutic strategies in breast cancer. Genomic, transcriptomic and clinical data from The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) breast cancer cohorts were used to examine statistical associations between tumor mutational burden (TMB) and the survival of patients whose tumors were assigned to previously-described prognostic immune subclasses reflecting favorable, weak or poor immune-infiltrate dispositions (FID, WID or PID, respectively). …

Outcomes In Deep Inferior Epigastric Perforator Flap And Implant-Based Reconstruction: Does Age Really Matter?, Lauren V. Kuykendall, Angie Zhang, Bugra Tugertimur, Sara Bijan, Corin Agoris, Ambuj Kumar, Deniz Dayicioglu

Surgery Faculty Publications

Despite the growing elderly population, there is limited research specific to this demographic concerning breast reconstruction (BR). Lack of evidence-based BR recommendations in older populations may contribute to misconceptions and subsequent underutilization of BR, especially autologous BR. Patients who received either deep inferior epigastric perforator (DIEP) flap BR or tissue expander/implant (TE/I) BR by a single surgeon between July 2011 and July 2015 were surveyed postoperatively by using the psychometrically validated BREAST-Q questionnaire to determine patient satisfaction. Patients were categorized into younger and older cohorts based on median age (55 years) and further stratified based on the type of reconstruction. …
