Breast cancer patients face challenges throughout the journey of diagnosis, treatment, post-treatment, and recovery. The breast cancer patient is exposed to a multidisciplinary team including doctors, nurses, therapists, counselors, and psychologists. While the team assembled together aims to address multiple facets in breast cancer care, the sub-specialized nature of individual professional practices may constrain the overview of patients' holistic needs and a comprehensive approach to cancer management. This paper aims to provide an overview of the holistic needs of breast cancer patients at each stage of their cancer journey, addressing their complex physical, psychological, and social needs...

BACKGROUND: Fat grafting has been widely indicated for postmastectomy and postlumpectomy breast reconstruction. The literature emphasizes the clinical efficacy of fat grafting, but experimental studies raise important questions about the recurrence risk because of the stimulation of remaining cancer cells by progenitor or adult adipocytes. Because breast conservative treatment provides a higher risk of residual cancer cells in the breast tissue compared with mastectomy, the authors set up a matched case-control study of fat grafting versus no fat grafting after breast conservative treatment...

BACKGROUND: In the debate on reconstruction of the irradiated breast, there is little information on associated health care resource use. Nationwide data were used to examine health care resource use associated with implant and autologous reconstruction. It was hypothesized that failure rates would contribute the most to higher average cumulative cost with either reconstruction method. METHODS: From the 2009 to 2013 MarketScan Commercial Claims and Encounters database, irradiated breast cancer patients who underwent implant or autologous reconstruction were selected...

PURPOSE: Data from large randomized controlled trials confirming sleep quality improvements with aerobic physical activity have heretofore been lacking for post-primary treatment breast cancer survivors. Our primary purpose for this report was to determine the effects of a physical activity behavior change intervention, previously reported to significantly increase physical activity behavior, on sleep quality in post-primary treatment breast cancer survivors. METHODS: Post-primary treatment breast cancer survivors (n=222) were randomized to a 3-month physical activity behavior change intervention (BEAT Cancer) or usual care...

High-precision fluorescence microscopy such as superresolution imaging or single-particle tracking often requires an online drift correction method to maintain the stability of the three-dimensional (3D) position of the sample at a nanometer precision throughout the entire data acquisition process. Current online drift correction methods require modification of the existing two-dimensional (2D) fluorescence microscope with additional optics and detectors, which can be cumbersome and limit its use in many biological laboratories...

OBJECTIVES: The aim of this study was to propose a magnetic resonance imaging acquisition and analysis protocol that uses image segmentation to measure and depict fluid, fat, and muscle volumes in breast cancer-related lymphoedema (BCRL). This study also aims to compare affected and control (unaffected) arms of patients with diagnosed BCRL, providing an analysis of both the volume and the distribution of the different tissue components. MATERIALS AND METHODS: The entire arm was imaged with a fluid-sensitive STIR and a 2-point 3-dimensional T1W gradient-echo-based Dixon sequences, acquired in sagittal orientation and covering the same imaging volume...

BACKGROUND: The Cancer Worry Scale was revised to be used in breast cancer genetic counseling (CWS-GC). This scale is used to identify dimensions that are relevant in the genetic counseling context, such as worry about developing breast cancer, impact of worries on daily life, and risk perception in women attending a counseling session for BRCA1/2 mutations. OBJECTIVE: The aim of this study was to estimate the psychometric properties of the CWS-GC in a sample of Italian women...

PURPOSE: Although clinical trials have provided some data on the benefit of angiotensin-converting enzyme inhibitors (ACEIs) or β-blockers (BBs) in patients with chemotherapy-induced cardiotoxicity, evidence of ACEIs/BBs on prevention of trastuzumab and/or anthracycline-induced cardiotoxicity outside trials is limited. MATERIALS AND METHODS: A cohort study of 142,990 women (66 y and above) newly diagnosed with breast cancer from 2001 to 2009 was conducted using the Surveillance, Epidemiology, and End Results-Medicare-linked database...

BACKGROUND: Breast cancer takes time for its survivors after a mastectomy to adjust to their changed bodies. There are limited studies about the process of how those survivors accept the changes of their bodies and how they reestablish their new selves. OBJECTIVE: The aim of this study was to understand the perception of body from women diagnosed with breast cancer more than 5years previously and whose treatment included a mastectomy. METHODS: A phenomenological method was applied to this study...

Cancer drug researchers have been seeking microtubule-inhibiting agents (MIAs) with higher bioactivity and lower toxicity than currently marketed drugs. WX-132-18B, a novel structural compound synthesized at our institute, specifically bound to the colchicine-binding site on tubulin rather than the vinblastine site, and concentration-dependently reduced microtubule content via depolymerization. It exhibited the same cellular phenotypic profiles as the classic MIAs (colchicine, vincristine, and taxol), including inducing cell cycle arrest at the G2/M phase, triggering tumor cell apoptosis, promoting nuclear membrane permeability, reducing mitochondrial membrane potential, and disrupting the redox system balance...

ERBB2 receptor belongs to the ERBB tyrosine kinase receptor family. At variance to the other family members, ERBB2 is a constitutively active orphan receptor. Upon ligand binding and activation, ERBB receptors form homo- or hetero-dimers with the other family members, including ERBB2, promoting an intracellular signaling cascade. ERBB2 is the preferred dimerization partner and ERBB2 heterodimers signaling is stronger and longer acting compared to heterodimers between other ERBB members. The specific contribution of ERBB2 in heterodimer signaling is still undefined...

Matrix metalloproteinase-14 (MMP-14) is a clinically relevant target in metastatic cancers due to its role in tumor progression and metastasis. Since active MMP-14 is localized on the cell surface, it is amenable to antibody-mediated blockade in cancer, and here we describe our efforts to develop novel inhibitory anti-MMP-14 antibodies. A phage-displayed synthetic humanized Fab library was screened against the extracellular domain of MMP-14 and a panel of MMP14-specific Fabs were identified. A lead antibody that inhibits the catalytic domain of MMP-14 (Fab 3369) was identified and treatment of MDA-MB-231 breast cancer cells with Fab 3369 led to significant loss of extracellular matrix degradation and cell invasion abilities...

Many studies have suggested that disialogangliosides, GD2 and GD3, are involved in the development of various tumor types. However, the functional relationships between ganglioside expression and cancer development or aggressiveness are not fully described. GD3 is upregulated in approximately half of all invasive ductal breast carcinoma cases, and enhanced expression of GD3 synthase (GD3S, alpha-N-acetylneuraminide alpha-2,8-sialyltransferase) in estrogen receptor-negative breast tumors, was shown to correlate with reduced overall patient survival...

In breast cancer (BC), up to 10-20% patients were known to have clinical benefit with immune checkpoint inhibitors, and biomarkers are needed for optimal use of this multi-potential therapeutic strategy. Accordingly, we conducted an experiment to identify expression of genes associated with immune checkpoints that represent potential targets of cancer immunotherapy. We performed whole-transcriptome sequencing and whole-exome sequencing using 37 refractory BC specimens. In the immune pathway gene set expression analysis, we found that HER2 expression and previous taxane treatment were positively correlated with high expression of immune gene set expression (p = 0...

Abemaciclib is an ATP-competitive, reversible kinase inhibitor selective for CDK4 and CDK6 that has shown antitumor activity as a single agent in hormone receptor positive (HR+) metastatic breast cancer in clinical trials. Here, we examined the mechanistic effects of abemaciclib treatment using in vitro and in vivo breast cancer models. Treatment of estrogen receptor positive (ER+) breast cancer cells with abemaciclib alone led to a decrease in phosphorylation of Rb, arrest at G1, and a decrease in cell proliferation...

Hematotoxicity is one of the major side effects of chemotherapy. The aim of this study was to examine the association between single nucleotide polymorphisms (SNPs) and hematotoxicity in breast cancer patients in a subset of patients of the SUCCESS prospective phase III chemotherapy study. All patients (n = 1678) received three cycles of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC) followed by three cycles of docetaxel or docetaxel/gemcitabine, depending on randomization. Germline DNA was genotyped for 246 SNPs selected from a previous genome-wide association study (GWAS) in a panel of lymphoblastoid cell lines, with gemcitabine toxicity as the phenotype...
