Due to increasing life expectancy, patients with breast cancer remain at risk of dying due to breast cancer over a long time. This study aims to assess the impact of age on breast cancer mortality and other cause mortality 10 years after diagnosis.
The development of a multidrug-resistant (MDR) phenotype is a main obstacle to the successful treatment of breast cancer. Saponins of several herbs are considered as promising candidates for drug resistance treatment. We extracted Paris saponin VII (PS VII) from Trillium tschonoskii Maxim. and investigated whether it could sensitize chemoresistant breast cancer cells MCF-7/ADR to the cytotoxic effects of adriamycin.
There is a well-known correlation between obesity, sedentary lifestyle, and breast cancer incidence and outcome. The Arbeitsgemeinschaft Medikamentöse Tumortherapie (AGMT) exercise study was a multicenter, randomized clinical trial and assessed the feasibility and efficacy of physical training in 50 breast cancer patients undergoing aromatase inhibitor treatment.
Breast cancer is the most common cancer of Finnish women. Peer support could be a way to help breast cancer patients to deal with the disease but studies on its effectiveness have produced conflicting results. The aim of this randomized controlled trial was to study the effectiveness of peer support on health-related quality of life (HRQoL) of breast cancer patients.
Concerns about breast cancer had become the most dangerous cancer to women over the world, more and more anti-cancer agents are developed to treat this malignancy. Pharmorubicin is a cytotoxic drug, widely used in the treatment of breast cancer, but its role is limited because of chemoresistance produced by cells. This study focused on exploring the influence of autophagy on the resistance of pharmorubicin in breast cancer cells.
Breast cancer is one of the most common malignant tumors among females. Recent studies demonstrated that microRNAs (miRNAs) played an important role in the regulation of tumor progression. In our present study, we firstly detected miR-340-5p expression in breast cancer cell lines and found lower expression of miR-340-5p in breast cancer cell lines (MCF-7, MDA-MB-231, BT-549, ZR-75-1) through qRT-PCR. Overexpressed miR-340-5p inhibited cell proliferation and drug resistance to docetaxel with enhanced cell ap...
Background/Introduction/Objective: Premenopausal women treated for breast cancer are at high risk for bone loss. This trial examined the effects of a 1-year combined aerobic and resistance exercise program on bone mineral density (BMD) in women treated for premenopausal breast cancer.
Despite the importance of chemotherapy in the treatment of early stage triple negative breast cancer (TNBC), no one optimal regimen has been identified. We conducted a pilot trial comparing outcomes for the three most commonly used chemotherapy regimens to assess the feasibility of conducting a larger definitive trial.
Re: The relationship between patient and tumor characteristics, patterns of breast cancer care, and 5-year survival among elderly women with incident breast cancer. Breast Cancer Res Treat. Sep 2018;171(2):477-488.
Breast cancer (BC) is a risk factor for major depressive disorder (MDD), yet little research has tested the efficacy of different psychotherapies for depressed women with BC. This study, the largest to date, compared outcomes of three evidence-based, 12-week therapies in treating major depressive disorder among women with breast cancer.
Metaplastic breast cancer (MpBC) is a rare but aggressive type of breast cancer accounting for 0.25-1% of all diagnosed invasive breast cancers. Morphologically, it is characterized by differentiation of the neoplastic epithelium into squamous cells and/or mesenchymal-looking tissue.
Histone deacetylase inhibitors (HDACi) are a relatively new class of drug that plays an important role in the epigenetic and non-epigenetic regulation in cancer, inducing death, apoptosis and cell cycle arrest in cancer cells. Although HDACi are approved only for hematologic malignancies, there are several trials in the breast cancer setting with promising results. In this review, we summarize the latest studies with HDACi in breast cancer from the emerging data in the translational research until its possi...
Triple-negative breast cancer (TNBC), an aggressive breast cancer subtype, is genetically heterogeneous which challenges the identification of clinically effective molecular makers. Extracellular vesicles (EVs) are key players in the intercellular signaling communication and have been shown to be involved in tumorigenesis. The main goal of this study was to evaluate the role and mechanisms of EVs derived from TNBC cells in modulating proliferation and cytotoxicity to chemotherapeutic agents in non-tumorigen...
Multidrug resistance (MDR) is the key cause that accounts for the failure of clinical cancer chemotherapy. To address the problem, herein, we presented an alternative strategy to conquer drug-resistant breast cancer through the combinatorial delivery of Ca channel siRNA with cytotoxic drug. Mesoporous silica nanocapsules (MSNCs) with mesoporous and hollow structure were fabricated for co-delivery of T-type Ca channel siRNA and doxorubicin (DOX) with high drug loading efficiency. The DOX/siRNA co-loaded MSNC...
The use of nanoparticulate systems with action in breast and ovarian cancer has been highlighted in recent years as an alternative to increasing the therapeutic index of conventional anticancer drugs. Thus, nanoparticles have advantageous characteristics in the treatment of cancer. Several nanocarriers of drugs and nanoparticles are described in the literature. The pharmacokinetics of the drugs can be modified by the use of nanocarriers, which in turn facilitate the specific delivery of the drug to the tumo...
The accumulating evidence indicates that weight gain in adulthood is more predictive of breast cancer risk than absolute body weight. However, the relative impact of timing of weight gain in adulthood on breast cancer as well as other characteristics of the association between weight and breast cancer has not been well documented.
Breast cancer is a global health issue and the second leading cause of cancer death in women. Breast cancer tends to migrate to bone and causes bone metastases which is ultimately the cause of death. Here, we report the use of FTIR to identify spectral biomarkers of cancer progression on 3D in vitro model of breast cancer bone metastasis. Our results indicate that the following spectral biomarkers can monitor cancer progression, for example, lipids (CH2 asymmetric/CH2 symmetric stretch), Amide I/Amide II, a...
Estrogens and estrogen receptors (ERs) regulate metabolism in both normal physiology and in disease. The metabolic characteristics of intrinsic breast cancer subtypes change based on their ER expression. Crosstalk between estrogen signaling elements and several key metabolic regulators alters metabolism in breast cancer cells, and enables tumors to rewire their metabolism to adapt to poor perfusion, transient nutrient deprivation, and increased acidity. This leads to the selection of drug-resistant and meta...
The scars derived from the treatment of breast cancer lead to adverse effects such as fibrosis or retractions of the connective tissue. Myofascial release (MR) seeks to reduce restrictions of the fascial system. Therefore, the aim of this study was to analyze the clinical impact of MR treatment on women survivors of breast cancer.
Assessing trends in breast cancer survival among young women who are largely unaffected by breast cancer screening will provide important information regarding improvements in the effectiveness of cancer care for breast cancer in the last few decades.
Observational studies of aspirin use and breast cancer risk have provided inconsistent results. The occurrence of contralateral breast cancer (CBC) among breast cancer survivors may serve as a useful high-risk model to identify preventive drug effects. Using this model, we examined the association between post-diagnosis use of low-dose aspirin and risk of CBC. We identified all women recorded with a first primary breast cancer in the Danish Breast Cancer Cooperative Group Database between 1996 and 2012. Inf...
Can Patients with Multiple Breast Cancers in the Same Breast Avoid Mastectomy by Having Multiple Lumpectomies to Achieve Equivalent Rates of Local Breast Cancer Recurrence? Response to the Preliminary Alliance 11102 Trial Report.
In the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial, patients with 1 or 2 tumour-involved sentinel lymph nodes (SLNs) gained no benefit from completion axillary lymph dissection (cALND). We examined implementation of evidence from this trial into routine clinical management.
Tumors that secrete large volumes of mucus are chemotherapy resistant, however, mechanisms underlying this resistance are unknown. One protein highly expressed in mucin secreting breast cancers is the secreted mucin, Mucin 2 (MUC2). While MUC2 is expressed in some breast cancers it is absent in normal breast tissue, implicating it in breast cancer. However, the effects of MUC2 on breast cancer are largely unknown. This study examined the role of MUC2 in modulating breast cancer proliferation, response to ch...
The potent antimalarial drug pyronaridine (PND) was tested for its potential as an anticancer drug. After exposing cancerous (17) and non-cancerous (2) cells to PND for 72 hr, PND was found to exhibit consistent and potent cytotoxic activity at low micromolar (μM) concentrations that ranged from 1.6 μM to 9.4 μM. Moreover, PND exerted a significant selective cytotoxicity index (SCI) on five out of seven breast cancer cell lines tested, with favorable values of 2.5 to 4.4, as compared with the non-cancero...
