Active clinical trials for "Breast Neoplasms"

This observational study will assess the safety of Herceptin (trastuzumab) in patients with HER2-positive breast cancer in routine clinical practice. Eligible patients will be followed for up to 4 years.

The purpose of this study is to assess the prevalence of cardiac dysfunction and (undiagnosed) heart failure in women registered in general practice with a history of breast cancer who received chemotherapy and / or radiotherapy as compared to a matched female control population.

Utilizing CellSearch® technology, the ability to both enumerate and reliably and reproducibly characterize circulating tumor cells (CTC) for tumor markers that predict endocrine sensitivity (estrogen receptor [ER] and Bcl-2) and resistance (HER2 and Ki67) has been demonstrated. An algorithm for a CTC-Endocrine Therapy Index (CTC-ETI) has been constructed that can be calculated for each patient using the CTC enumeration and marker results. The primary goal of this study is to determine a CTC-ETI in ER positive, HER2 negative metastatic breast cancer patients before the initiation of a new endocrine therapy for the identification of patients that will progress rapidly.

Over the last decades different life style factors have been established as risk factors for various diseases. The obesity pandemic displays a good example of a disease where great effort is undertaken to characterize risk factors associated with obesity (1). Smoking is another life style risk factor established since several decades, and where primary prevention has been increasingly successful (2, 3). Cardiovascular epidemiologic research at the University of Gothenburg recognized PA as a factor of importance early on and thus included PA related questions in the work up of studies with large cohorts (4-6). A 4-level scale was introduced in the late 1960:s by Saltin and Grimby (7) and has been used extensively since then. With this background it is of interest to record physical activity one year and one month prior to certain types of elective surgery and to study the relationship of PA to surgical complications and recovery is of interest. The aim of this study is to investigate whether a higher physical activity prior to a surgical procedure reduces hospital stay, sick leave and the complication rate. A secondary aim is to investigate the effect of preoperative physical activity on the rate of resumption of QoL and normal physical function.

This prospective observational study will evaluate the use in clinical practice, efficacy and safety of Avastin (bevacizumab) in combination with paclitaxel in first line in patients with HER2-negative metastatic breast cancer. Data will be collected from eligible patients for up to 2.5 years.

The purpose of this study is to evaluate a side effect prevention training (SEPT) that optimizes patients' response expectations before the start of adjuvant endocrine treatment (AET) to prevent nocebo side effects and enhance quality of life during longer term drug intake.

This multicenter observational study will evaluate the efficacy and safety of Xeloda (capecitabine) in combination with docetaxel in first-line therapy in participants with HER2-negative metastatic breast cancer. Participants will be followed for approximately 6 months of treatment.

The study is based on the identification of sentinel node(s) by SENTIMAG / SIENNA + in addition to the usual method (blue and /or radioactive product). This is a feasibility study

Regional lymph node status is the most important prognostic factor for disease-free and overall survival in breast cancer. Accurate nodal staging can be achieved only by surgery. Today, in early-stage invasive breast cancers with clinically negative lymph nodes, minimally invasive sentinel lymph node biopsy (SLNB) is considered the gold standard of regional lymph node staging. To optimize the effectiveness of SLNB, precise pre-and intraoperative mapping of lymphatic drainage is important. The (SLNB) technique is not standardized. The most common and most accurate way of lymphatic mapping is performed with the combined application of a gamma-emitting isotope labeled substance and blue dye, the so-called double labeling technique. Functional lymphatic drainage of SLNB double staining in the mammary gland, skin and axilla present a number of uncertainties. According to the axillary, lateral thoracic and thoracodorsal veins, Ibusuki et al. divided the axillary region into four subregions: brachial (lateral), pectoral (anterior), central and subscapular (posterior) zones. They revealed clear relationship between the anatomic location and status of the SLN, also confirmed by Gallowitsch et al. SLN was detected in Level I in 96% and in Level II in 4% by SPECT/CT. Knowedge of relationships between the drainage of sentinel lymph node staining into the axillary subregions, location of the primary tumor, tumor size, SLN positivity and its location within the subregion are of particular importance in the decision making whether or not axillary lymphadenectomy (ALND) needs to be performed. In the prospective randomized phase 3 trial by Giuliano et al. (ACOSOG Z-11) ALND was not performed in early breast cancer patients with clinically negative axilla and breast-conserving surgery, for 1-2 macroscopically positive SLNs (10). After an average follow-up of 6.3 years, data were compared to the traditional ALND group and no difference was detected in 5-year overall survival or disease-free survival at 5 years. Aims of the investigation: To examine the location of SLN in the axillary subregion (anterior, posterior, central, lateral, apical) in patients with early breast cancer (T <5 cm). To statistically assess correlations between the location, size, histological parameters of primary breast tumor and the subregion of the SLN. To statistically assess SLN positivity and its location within the sbregion. To statistically assess subregional localisation of positive SLN and the number of all positive regional lymph nodes, to predict a limited number of cases with lymph node metastasis, based on the test results of the ACOSOG Z-11 trial, by which ALND could be omitted.

Deciding whether or not to have breast reconstruction after mastectomy is highly challenging for many patients. This study will examine patients' decisions about reconstruction and the effects of reconstruction on quality of life and body image.
