Danazol, the established clinical drug has given promising therapeutic results in a series of clinical trials with breast cancer patients. Danazol shares structural similarities with several known PKC agonists and fits well into the C1 domain. Danazol binds to the C1b domain of PKC with Kd of 5.64±1.27 μM. MD simulation studies further support that the PKC-Danazol molecular model is stable and showing minimum distortion to the structure during the simulation period. Immunofluorescence and western-blotting studies indicate that MDAMB-231 cells stimulated with danazol exhibit translocation of PKCα to the plasma membrane...

The aim of this study was to present our experience with primary breast angiosarcoma (PBA) by describing a large series of cases with an emphasis on clinicopathologic and radiologic correlations. Thirty-six cases of PBA diagnosed at our institution between 2006 and 2014 were retrospectively evaluated. All but one case occurred in women with a median age of 35.5 years. The majority of patients presented with a deeply located painless mass, whereas a minority manifested as diffuse enlargement or swelling of the breast...

Human 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1), a potential target in breast cancer prevention and therapy, was extracted from human placenta and immobilized on nonporous silica (∼5 μm) with a covalent method for the first time. The optimum initial enzyme concentration and immobilization time during the immobilization process were 0.42 mg mL(-1) and 12 h, repectively. The binding was confirmed by scanning electron microscope (SEM) and infrared spectroscopy (FT-IR). It could improve the pH, thermal and storage stability compared to free enzyme...

PURPOSE: We studied elderly Medicare enrollees newly diagnosed with early-stage breast cancer to examine the association between adjuvant chemotherapy and acute kidney injury (AKI). METHODS: Using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we conducted a retrospective cohort study including women diagnosed with stages I-III breast cancer at ages 66-89 years between 1992 and 2007. We performed one-to-one matching on time-dependent propensity score on the day of adjuvant chemotherapy initiation within 6 months after the first cancer-directed surgery based on the estimated probability of chemotherapy initiation at each day for each patient, using a Cox proportional hazards model...

PURPOSE: To investigate and compare the effects of mobile health (mHealth) and pedometer with conventional exercise program using a brochure on physical function and quality of life (QOL). METHODS: The study was a prospective, quasi-randomized multicenter trial where 356 patients whose cancer treatment had been terminated were enrolled. All patients were instructed to perform a 12-week regimen of aerobic and resistance exercise. The mHealth group received a pedometer and a newly developed smartphone application to provide information and monitor the prescribed exercises...

REVIEW

Cancer treatments such as chemotherapy have been an important part of extending survival in women diagnosed with breast cancer. However, chemotherapy can cause potentially toxic side effects in the brain that impair memory, verbal fluency, and processing speed in up to 30% of women treated. Women report that post-chemotherapy cognitive deficits negatively impact quality of life and may last up to ten years after treatment. Mechanisms underlying these cognitive impairments are not fully understood, but emerging evidence suggests that chemotherapy induces structural changes in the brain, produces neuroinflammation, and reduces adult hippocampal neurogenesis...

Over the past several years, there has been an increasing rate of bilateral prophylactic mastectomy (BPM) and contralateral prophylactic mastectomy (CPM) surgeries. Since publication of the 2007 SSO position statement on the use of risk-reducing mastectomy, there have been significant advances in the understanding of breast cancer biology and treatment. The purpose of this manuscript is to review the current literature as a resource to facilitate a shared and informed decision-making process regarding the use of risk-reducing mastectomy...

Metastasis is one of the most characteristic yet problematic behaviors of cancer cells. Stage IV breast cancer accounts for a large portion of breast cancer-related morbidity and mortality. Despite early detection and improvement in survival owing to advancements in biomedical research and overall improvement of the health system, 6-10% of patients present with stage IV disease in the developed world, with a higher incidence noted elsewhere. Despite advances in biomedical research into cancer, up to 70-80% of patients with stage IV breast cancer die of cancer in 5 years, a disproportionally higher mortality compared with non-metastatic breast cancer...

PURPOSE: To compare the disease-free survival (DFS) and overall survival (OS) rates of men and women undergoing treatment for breast cancer. METHODS: A retrospective cohort study of patients with breast cancer diagnosed and treated at the Cancer Hospital III of the National Cancer Institute of Brazil, Rio de Janeiro, Brazil, between 1999 and 2013. Male breast cancer cases were matched for age, year of diagnosis, and clinical staging to three female cases (1:3). Patient characteristics were abstracted from hospital records and medical charts...

Obesity is a worldwide epidemic, and the comorbidities associated with obesity are numerous. Over the last two decades, we and others have employed an outbred rat model to study the development and persistence of obesity, as well as the metabolic complications that accompany excess weight. In this review, we summarize the strengths and limitations of this model and how it has been applied to further our understanding of human physiology in the context of weight loss and weight regain. We also discuss how the approach has been adapted over time for studies in females and female-specific physiological conditions, such as menopause and breast cancer...

BACKGROUND: Patients with metastatic breast cancer often have pulmonary symptoms with varying aetiologies. Transtuzumab is an extremely important drug used in the treatment of Her 2 neu over-expressing breast cancers. In this report we describe a case of organizing pneumonia associated with use of transtuzumab in metastatic breast cancer. Only three such cases have previously been reported. CASE DESCRIPTION: A 43 year old lady with Her 2 neu 3+, estrogen and progesterone receptor positive, metastatic breast cancer was started on weekly transtuzumab and albumen bound paclitaxel...

BACKGROUND: Among HIV-1-exposed infants, mixed breastfeeding is associated with higher postnatal HIV-1 transmission than exclusive breastfeeding, but the mechanisms of this differential risk are uncertain. METHODS: HIV-1-exposed, Ugandan infants were prospectively assessed over the first year of life for feeding practices and T cell maturation, intestinal homing (β7(hi)), activation, and HIV-1 co-receptor (CCR5) expression in peripheral blood. Infants receiving only breast milk and those with introduction of other foods prior to 6 months, categorized as exclusive and non-exclusive, respectively...

BACKGROUND: Hispanic women have lower breast cancer incidence rates than non-Hispanic white (NHW) women. To what extent genetic versus non-genetic factors account for this difference is unknown. METHODS: Using logistic regression, we evaluated the interactive influences of established risk factors and ethnicity (self-identified and identified by ancestral informative markers) on breast cancer risk among 2326 Hispanic and 1854 NHW postmenopausal women from the US and Mexico in the Breast Cancer Health Disparities Study...

RATIONALE: In early-stage breast cancer, the primary treatment option for the majority of women is breast-conserving surgery (BCS). There is a clear need for more accurate techniques to assess resection margins intraoperatively, as on average 20% of patients require further surgery to achieve clear margins. Cerenkov luminescence imaging (CLI) combines optical and molecular imaging by detecting light emitted by (18)F-fluorodeoxyglucose ((18)F-FDG). Its high-resolution and small size imaging equipment makes CLI a promising technology for intraoperative margin assessment...

AIM: To determine the frequency of and reasons for false-negative breast magnetic resonance imaging (MRI) examinations in high-risk women undergoing annual screening. MATERIALS AND METHODS: The family history clinic database was interrogated and women at high risk of breast cancer who had undergone screening MRI and been diagnosed with breast cancer within 2 years of the MRI examination were identified. All available MRI examinations were reviewed and classified by two radiologists...
