This is a prospective, observational, open-label trial with a target enrollment of 1400 subjects. Primary endpoint The primary aim of this study is to determine the incidence of febrile neutropenia. Secondary endpoint Major secondary endpoint include a) Incidence of bone pain, b) All adverse events, c) Percentage of patients with RDI (relative dose intensity) ≥ 85%

The MARIEplus study is a prospective cohort of breast cancer patients recruited into the MARIE (Mamma Carcinoma Risk factor InvEstigation) study, a population-based case-control study of breast cancer conducted in two German study regions, Hansestadt Hamburg and Rhine-Neckar-Karlsruhe (RNK) region. Participants were identified through participating clinics and the Hamburg cancer registry between January 1st, 2001 and September 30th, 2005 in Hamburg and between August 1st, 2002 and July 31st, 2005 in the RNK study region. Patients were aged 50-74 years at histologically confirmed primary invasive (stages I to IV) or in situ breast tumor (stage 0). Comprehensive information on demographic, socio-economic, and lifestyle factors was collected at multiple time points: at recruitment by a standardized face-to-face interview and at follow-up median 6 years as well as 11 years later using computer assisted telephone interview. Vital status was assessed in 2009 and again in 2015 via the population registries and causes of death were obtained from death certificates and coded according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Information on the clinical course was abstracted from medical records to verify clinical events either self-reported in follow-up interviews or reported by treating physicians. The studies were approved by the ethics committee of the University of Heidelberg and the University of Hamburg and conducted in agreement with the Helsinki Declaration. Written informed consent was provided by all participants at baseline and during follow-up. The primary objectives of this study are To assess the association of modifiable lifestyle factors and personal factors, including BMI, diet, physical activity, tobacco and alcohol use, menopausal hormone therapy, socioeconomic status, with breast cancer survival, overall and according to tumor type, after accounting for established prognostic factors. To examine the influence of genetic variants on breast cancer relapse and survival To assess the association of lifestyle factors and their changes in the course of survivorship on subsequent breast cancer prognosis. To assess the individual and combined association of inflammation/metabolic biomarkers as well as changes in their serum levels with subsequent breast cancer prognosis overall and according to tumor type. To assess whether and to what extent the associations between breast cancer prognosis and lifestyle factors and/or their changes are mediated by circulating biomarker levels.

This randomized trial studies how well a mindfulness-based stress reduction program helps participants with breast cancer that has spread to other places in the body. A cancer diagnosis is a life-changing and highly stressful event for most people, often resulting in marked declines in quality of life both during and after treatment. There are approximately 3 million women living with a history of invasive breast cancer in the U.S., with at least 150,000 living with metastatic disease. Patient preferences suggest a high need for complementary and alternative medicine interventions to address these chronic symptoms. Mindfulness-based stress reduction programs may help women living with metastatic breast cancer manage symptoms related to cancer treatment and improve quality of life.

Globally, breast cancer is the most common cancer and the main cause of deaths due to cancer. This is attributed to changes in reproductive habits as well as an increasingly sedentary lifestyle, with low physical activity and diets rich in saturated fats but low in fiber. While the main focus in many Asian countries is to improve survival from breast cancer by encouraging early detection of the disease and improving access to cancer treatment, it does not reduce the number of women who will be diagnosed with breast cancer in the years to come. Currently, there is an urgent need to develop effective strategies to prevent breast cancer in Asia and beyond. Soy may be an important dietary strategy for breast cancer prevention. Compared to women in the West, Asian women consume up to 10-fold more soy in their diet, which may, in part, explain their lower risk of breast cancer. Soybeans are rich in isoflavones, which can mimic estrogenic activity. In the body, it competes with estrogen and binds to estrogen receptor sites, thereby reducing the effect of estrogen and possibly lowering breast cancer risk. Consistently, research has shown that Asian postmenopausal women who have high soy diets are less likely to be diagnosed with breast cancer. However, researchers have not been able to show that postmenopausal women can reduce their breast cancer risk by increasing soy intake as part of their diets. There are several reasons why these studies have failed to see an effect despite the body of evidence indicating that soy may be protective. Firstly, these are studies of Caucasian women who may have never been exposed to soy, particularly in adolescence, where soy may have the greatest impact. Also, these studies have used soy isoflavone supplements, rather than traditional soy foods made from whole soybeans, which may affect how soy is metabolized in the body. Lastly, the way in which mammographic density measurements were obtained previously could have negatively influenced the study results, such as the use of digitized images of mammogram films rather than raw digital images and the use of semi-automated methods that may be subject to human error and reader variability. Therefore, a well-designed intervention study among Asian women living in Asia, using suitable mammographic density measures as a surrogate marker of breast cancer risk, will best answer these remaining gaps in our knowledge about the soy-breast cancer relationship.

Breast cancer is the most common cancer among women in Norway. In 2016, 3402 new cases were diagnosed (3371 in women). Breast cancer is still the second most common cause of death from cancer among women with 585 breast cancer deaths in Norway in 2015. The majority of the patients (70-75 %) belong to the Luminal subtypes, which comprise the hormone receptor (oestrogen receptor (ER) and/or progesterone receptor (PR)) positive tumours. The most important systemic adjuvant therapy in luminal breast cancers is a long-lasting administration of per-oral anti-oestrogen medication. A systemic hypo estrogenic state in the body may be created by the selective oestrogen receptor modulator tamoxifen or by inhibitors of the peripheral systemic aromatization of adrenal androgens into estrogens (aromatase inhibitors). Initially, tamoxifen was given adjuvant for 2 years, later prolonged to 5 years and recently an extension to 10 years has been recommended for premenopausal women. Aromatase inhibitors were introduced in Norwegian treatment guidelines in 2002. Currently, they are recommended in postmenopausal patients for 5 years, either as monotherapy or in concert with tamoxifen (aromatase inhibitors for 2 years followed by tamoxifen for 3 years). In premenopausal breast cancer patients, tamoxifen still is the drug of choice. Two of the major underlying reasons for late recurrences in luminal breast cancer subtypes are development of endocrine resistance to tamoxifen and aromatase inhibitors or failure of taking the medication as prescribed. Higher mortality has been shown for breast cancer patients with reduced tamoxifen adherence. The patients' ability to follow instructions and recommendations are probably overestimated in controlled trials due to patient selection and close follow-up in the study setting. Some patients experience distressing side effects like hot flushes, fatigue, joint pain, mood swings and vaginal dryness. To the investigators' knowledge, there are few studies in Norway regarding discontinuation of endocrine treatment in breast cancer. In this study they will investigate the long-term discontinuation pattern to oral adjuvant systemic endocrine therapy in a large cohort of breast cancer patients treated in St. Olav's hospital in Trondheim, Norway, and the association between adherence to endocrine treatment and long-term survival.

In this prospective study, breast capsule biopsy was performed in patients undergoing 2-stage expander-implant breast reconstruction to determine its use. Prospective clinical trial was designed for 10 consecutive patients as a pilot study and approved by IRB of Samsung Medical Center. From November 2013 to May 2015, full-thickness capsule biopsy specimen was obtained from acellular dermal matrix (ADM) capsule and from native subpectoral capsule (internal control) during expander-implant exchange. Biopsy specimens were scored for fibrosis and inflammatory reactions. This is completed study and its specific title, study objective, method, and results will be available online after scientific journal submission.

The purpose of this study is to test the usability of the Plan To Thrive smartphone application with cancer survivors. This study will involve three visits (baseline, follow-up, and feedback assessments). Between the baseline and follow-up time points, patients will undergo a 90-day period in which they will engage with app content. It is hypothesized that cancer survivors in this study will find the smartphone application, Plan to Thrive, an acceptable and feasible way to access post-treatment information. In addition, the investigators will explore preliminary efficacy by examining changes over time in primary (patient activation, patient knowledge and adherence to follow-up care recommendations and health behaviors) and secondary outcomes [symptom burden, health-related quality of life and patient satisfaction].

Some women are more likely to get breast cancer as it runs in their family, they are at risk of familial breast cancer. There are medications, called chemoprevention, which may lower their risk of developing breast cancer by a third. However chemoprevention can also cause serious side effects, like womb cancer and blood clots. This makes decision to start them difficult. Researchers found that not all women who can have these medications are on them. The investigators want to ask familial breast cancer specialists whether they recommend general practitioners (GP) to prescribe chemoprevention, by sending them a short survey. These specialists look after women where breast cancer runs in the family. The specialists assess a women's chance of getting breast cancer and advice those with increased risk what can be done to prevent breast cancer. The investigators will then look at whether specialist recommendation makes a difference to whether GPs prescribe chemoprevention medication. This will be done by linking the specialists' survey response to information on GP prescribing that the government regularly publishes. This may help the investigators understand why chemoprevention is not used as often as it potentially can be.

The aim of this study was to investigate the quality of life (QoL) for women with breast cancer in Taiwan after using the BCSMS App.

Survival of breast cancer patients has improved with multimodality treatment. Hypofractionated radiotherapy (RT) is rapidly emerging as one of the options for breast cancer patients after breast conservation surgery (BCS) but data on postmastectomy radiation therapy (PMRT) with hypofractionation is lacking and there is always concern for the late effects of RT especially with regional nodal irradiation (RNI). The potential survival benefits of locoregional radiation needs to be balanced with late-term effects. There is a dearth of data on RNI with hypofractionation. Therefore, reporting late-term effects of radiation in these patients is of utmost importance, especially with hypofractionation. Very few patients were given PMRT or RNI in the START trials, so definitive conclusions about the safety of shorter fractionation RNI cannot be drawn from these studies.1-3 There are also studies from Canada and the US with similar dose fractionations in the PMRT setting with limited number of patients but without RNI.4,5 There is a world-wide need for data on PMRT and especially with RNI for patients with breast cancer with its late-term consequences. Because of this, many radiation oncology societies are hesitant in recommending hypofractionated RNI. It is also an area for potential research in breast cancer radiotherapy. We have published our clinical outcomes with 3 weeks of adjuvant local and RNI with hypofractionation in the past.6-10 In this study, we will report late-term effects of PMRT and RNI with this schedule in patients with stage II and III breast cancer from a single institute from India which is practicing hypofractionation since 1976.
