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 study examines effectiveness of peer support of breast cancer patients. Half of the participants received peer support via telephone in addition to usual care and another half are give the usual care only.
Because of mammography screening increasingly more women are diagnosed with centimeter or subcentimeter node-negative breast cancer (i.e., T1abN0); these tumors account for approximately 19% of all newly diagnosed breast cancers in Sweden. Although the long term relapse-free survival rates among patients with such tumors is as high as ≥90%, some reports suggest that certain patient subgroups may have rates <75%. Firmly established prognostic and predictive factors for patients with T1abN0 tumors are, however, lacking. This is a nationwide, register-based cohort study investigating prognostic and predictive factors in women with centimeter or subcentimeter breast cancer. The study hypotheses are: 1) Established prognostic and/or predictive factors in overall breast cancer are prognostic and/or predictive factors also in centimeter or subcentimeter node-negative breast cancer; 2) The established relative reduction in risk of recurrence and death of adjuvant treatment for overall breast cancer are similar in centimeter or subcentimeter node-negative breast cancer.
Breast cancer patients scheduled to receive myelosuppressive chemotherapy (AC regimen) will be enrolled in this study. Eligible patients receive single SC injection of pegcyte or neulastim 24 hours after administration of chemotherapy (Doxorubicin and Cyclophosphamide) in the first cycle (14 days each cycle). Blood samples are collected to determine the serum concentration of investigational drugs at specific time points in the first cycle. Absolute neutrophil count, CD34+ count, Cmax (maximum serum concentration), AUC0-t (area under the curve of the plasma concentration time) and Tmax (time required to reach Cmax) will be calculated from the serum concentration profile
Breast cancer is the most prevalent cancer among women worldwide . 5 years after diagnosis, up to 87% survives. A substantial group of these survivors report reduced physical, psycho social and cognitive functioning. Therefore, it is increasingly important to screen for distress, both during and after treatment. The Distress Barometer (DB) is a valid, short screening instrument, used to detect elevated levels of distress in patients with cancer. It can be used either in a self-report questionnaire or in an interview format. Although the DB is used in different ways, it remains unclear whether both assessment methods would generate similar results, and which format is most suitable to represent the actual level of distress. Existing literature on the DB lacks a systematic description of the relationship between the method of assessment and the patients' responses. This study questions whether the written and interview variants of the DB reveal different results in the same patients with breast cancer.
The goal of this project is to test the effects of the Patient Preference Scale as the basis for a clinical intervention for role negotiation in breast cancer surgery decisions and the Patient Perception Scale to measure role concordance. The investigators hypothesize that better role concordance will be achieved with a simple provider-based intervention. In the first half of the study, providers will be blind to the patient's preferred role. In the second half, providers will be made aware of the preferred role prior to the encounter and will have a brief conversation with the patient about their desired role in the decision making process.
The purpose of the present study was to test the hypothesis that doxorubicin and cyclophosphamide adjuvant chemotherapy (CHT) acutely induces neurovascular and hemodynamic changes in patients with breast cancer. To test this hypothesis, women with breast cancer (stage II-III) underwent two experimental sessions, saline (SL) and CHT. In the CHT session, doxorubicin (60 mg/m2) and cyclophosphamide (600mg/m2) were administred in 45 min. In the SL session, a matching saline volume to that of the CHT session was infused over 45 min.
A brief psychosocial intervention for partners of women affected by or at risk for breast cancer and harboring BRCA genetic alterations.
General anesthesia is the conventional technique used for breast surgery. breast surgery is associated with a high incidence of postoperative pain, it is estimated that over 50 % of women suffer chronic pain following breast cancer surgery. Regional anesthesia is a good alternative to general anesthesia for breast cancer surgery, providing superior analgesia and fewer side effects related to a standard opiate-based analgesia. there is no evident optimal regional techniques for operative procedures on the breast and axilla, like high thoracic epidural, cervical epidural, paravertebral block, intrerpleural block, PECs block, serratus plane block and segmental thoracic spinal anesthesia. Regional anesthesia decreases operative stress, provides beneficial hemodynamic effects especially for critically ill patients and decreases postoperative morbidity and mortality. Also it reduces post‑operative nausea and vomiting and provides prolonged post‑operative sensory block, minimizing narcotic requirements. Additionally, this application positively affects the early start of feeding and mobilization.
