Triple negative breast cancer (TNBC) is a heterogenous disease with high aggressive and poor outcome. The lack of biomarkers and targeted therapies makes it a challenge for the treatment of TNBC. Histone deacetylase inhibitors (HDACis) are emerging as novel anti-tumor agents in many types of human cancers. In this study, we found that I-7ab, a novel HDACi, inhibited the cell viability of TNBC cells and induced the cell apoptosis. Mechanistically, I-7ab specifically decreased the expression of HDAC3 and promoted the acetylation of p53 at both Lys373 and Lys382 amino acids...

Nanotechnology possesses the potential to revolutionize the diagnosis and treatment of tumors. The ideal nanoparticles used for in vivo cancer therapy should own long blood circulation and active cancer targeting. Additionally, they should be innoxious and invisible to the immune system. Here, we developed a biomimetic nanoplatform with the above properties for cancer therapy. Macrophage membranes were reconstructed into vesicles and then coated onto magnetic iron oxide nanoparticles (Fe3O4 NPs). Inherited from the Fe3O4 core and the macrophage membrane shell, the resulting Fe3O4@MM NPs exhibited good biocompatibility, immune evasion, cancer targeting, and light-to-heat conversion capabilities...

BACKGROUND: Breast cancer is an alarming global public health problem and a main cause of cancer-related death in women. Systemic chemotherapy is the most widely used treatment for breast cancer. However, current chemotherapy treatments are far from desirable due to poor targeting specificity, severe side effects, and vasculogenic mimicry (VM). PURPOSE: Hyaluronic acid (HA) modified daunorubicin plus honokiol cationic liposomes were prepared and characterized for treatment of breast cancer by eliminating VM...

Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype characterized by poor patient prognosis and for which no targeted therapies are currently available. TNBC can be further categorized as either basal-like (BLBC) or quintuple-negative breast cancer (QNBC). In the present study, we aimed to identify novel molecular therapeutic targets for TNBC by analyzing the mRNA expression of TNBC-related genes in publicly available microarray data sets. We found that Engrailed 1 (EN1) was significantly overexpressed in TNBC...

Human epidermal growth factor receptor 2 (HER2) positive is a unique molecular subtype of breast cancer (BC) characterized by high malignancy and poor prognosis. Bilateral primary breast cancer (BPBC) harboring HER2 gene amplification is available to be detected among the BC survivors due to the increasing use of anti-HER2 adjuvant therapy. However, owing to the paucity of cases reported, knowledge of treating HER2-positive BPBC patients including the clinical behavior, histopathologic characteristics, anti-HER2 therapeutic response and disease outcome are not fully understood...

Together with surgery and radiotherapy, systemic treatment with cytotoxic chemotherapy and molecular targeted agents is one of the main therapeutic pillars in the treatment of soft-tissue sarcomas and is the mainstay of treatment in patients with advanced or metastatic disease. Unlike other more common malignancies such as breast and colorectal cancer, the role of chemotherapy when used in the adjuvant setting in soft-tissue sarcomas is less well defined. Results from prior studies have been conflicting, in part due to the heterogeneity and rarity of the disease, and large-scale meta-analysis has been performed to address this issue...

BACKGROUND Carbobenzoxy-L-leucyl-L-leucyl-L-leucinal (MG132), a peptide aldehyde proteasome inhibitor, can inhibit tumor progression by inactivating nuclear factor (NF)-κB signaling. Paclitaxel (PTX) is part of a routine regimen for the treatment of breast cancer. However, activation of the NF-κB pathway after treatment with PTX confers insensitivity to this drug. This study investigated the potential effect of MG132 as a co-treatment with PTX against breast cancer, and clarifies the underlying molecular mechanisms...

PURPOSE: Breast cancer is the second most frequently diagnosed cancer and is considered as the main cause of cancer related death in females. It is estimated that about one-third of women with breast cancer develop metastases and eventually die of this disease. The main treatment options for breast cancer include surgical interventions followed by chemotherapy, hormonotherapy or radiation. However, the side effects associated with the treatment of breast cancer negatively affects the quality of patient's life...

IMPORTANCE: Significant variation in the number and types of oncologists that provide breast cancer follow-up exists. However, there is limited understanding regarding breast cancer survivors' preferences for who provides their follow-up. Our objective was to explore breast cancer survivors' perspectives on the goals of breast cancer follow-up, the preferred role for primary care providers, and the perceived roles of different types of oncologists during follow-up. METHODS: A convenience sample of stage 0-III breast cancer survivors was identified and in-depth one-on-one interviews conducted...

PURPOSE: Only recently has breast cancer survivorship earned formal recognition as a research discipline. Complicating survivorship research is the frequent overlap between aging and treatment sequelae. The ACS/ASCO 2016 Breast Cancer Survivorship Care Guideline (Guideline) reflects comprehensive literature review through April 2015, while the jointly sponsored, inaugural Cancer Survivorship Symposium in 2016 (Symposium) reflects ongoing research activity in the area. Together, these platforms provide an opportunity to examine the use of randomized trials and controlled studies in survivorship care research...

Phosphoinositide 3-kinase (PI3K) inhibitors may overcome drug resistance and improve advanced breast cancer (ABC) outcomes. We conducted a systematic review and meta-analysis to assess the efficacy and safety of adding a PI3K inhibitor to the standard of care (SOC) treatment in ABC. The electronic databases Ovid, PubMed, Cochrane Central Register of Controlled Trials and Embase, were searched for relevant randomised trials. Pooled hazard ratios (HRs) for progression-free survival (PFS) and pooled risk ratios (RRs) for objective response rates (ORRs), disease control rates (DCRs) and toxicity were meta-analysed using the Mantel-Haenszel method and generic inverse variance...

Malignant cells are not the only components of a tumor mass since other cells (e.g., fibroblasts, infiltrating leukocytes and endothelial cells) are also part of it. In combination with the extracellular matrix, all these cells constitute the tumor microenvironment. In the last decade the role of the tumor microenvironment in cancer progression has gained increased attention and prompted efforts directed to abrogate its deleterious effects on anti-cancer therapies. The immune system can detect and attack tumor cells, and tumor-infiltrating lymphocytes (particularly CD8 T cells) have been associated with improved survival or better response to therapies in colorectal, melanoma, breast, prostate and ovarian cancer patients among others...

Adjuvant radiotherapy after breast-conserving surgery has been an important component of the standard of care for early breast cancer. Improvements in breast cancer care have resulted in a substantial reduction in local relapse rates over recent decades. Although the proportional benefits of adjuvant radiotherapy are similar for different prognostic risk groups of patients, the absolute benefits depend on the risk of relapse and therefore vary considerably between prognostic groups. Radiotherapy is not without risk and for some patients at very low risk of relapse the risks of radiotherapy may outweigh the benefit, leading to potential overtreatment...

BACKGROUND: Background: Bisphenol A (BPA) is an estrogen-like chemical widely contained in daily supplies. There is evidence that environmental exposure to BPA could contribute to the development of hormone-related cancers. As is reported in numerous studies, melatonin, an endogenous hormone secreted by the pineal gland, could markedly inhibit estrogen-induced proliferation of breast cancer (BC) cells. In this study, we intended to reveal the effects of melatonin on BPA-induced proliferation of estrogen receptor-positive BC cells...
