Active clinical trials for "Breast Neoplasms"

Randomized trial comparing the performance of tomosynthesis and 2D Digital Mammography vs 2D Digital Mammography only in respect to incidence of advanced cancers (interval and following round) and interval cancers.

The aim of this non-interventional study is to assess oral vinorelbine dose schedules (initial dose, dose increase/maintenance/reduction) applied during the initial 8 weeks of treatment under routine conditions in Germany together with the underlying reasons for the respective chosen schedules.

This non-interventional study will collect data from routine diagnostics on HER2 testing of breast cancer in Germany.

The purpose of the study is the identification and quantification of proteins expression level in breast cancer tissues. The imaging system is intended for diagnostic use as an aid to the pathologist in the detection, counting and classifying ER/PR IHC stained samples.

Firstly, the investigators aim to show that breast tumour blood flow, measured as part of a standard MRI examination, decreases at the earliest stage of neoadjuvant chemotherapy in those patients who go on to respond to treatment. Importantly, the investigators will also show that blood flow does not decrease in those patients who fail to respond. Secondly, the investigators will test whether the decrease in tumour blood flow over the whole course of neoadjuvant chemotherapy can predict the response of the tumour measured at the time of surgery.

Radioisotopic and wire localizations suffer from several limitations. These techniques add another procedure prior to surgery, can be uncomfortable and entail additional cost. The aim is to develop a novel technique of breast tumor localization using preoperative magnetic resonance imaging (MRI) and breast optical scanning. Patients with diagnosis of breast cancer who have had a preoperative MRI and 3D optical scans are included. Optical scanning is done preoperatively and intraoperatively after tumor localization was marked on the breast using radioisotopic technique. The MRI is then adjusted with the intraoperative optical scan to match the breast position at the time of surgery. The investigators evaluate the efficiency for localization of breast lesion of the novel technique by comparison with radiosiotopic technique.

The aim of this study is to evaluate a new method for the localization of breast cancer sentinel lymph node using Sienna+® and Sentimag® detection in comparison to our standard techniques with radio-isotopes.

Operable early stage breast cancer patients staged according to NCCN guidelines are subjected to bone marrow aspiration/trephine biopsy at the time of the definitive operation under general anesthesia. The specimen will be fixated in neutral tamponaded formalin and the sections will be examined by H&E and cytokeratin immunohistochemically. If disseminated tumor cells are identified ER (estrogen receptor), PR (progesterone receptor), HER2/neu will be studied. Disseminated tumor cells will be recorded quantitively and semiquantitatively. Results of the pilot study will be evaluated as observational study.

This is a single institution, prospective screening trial of women at high risk for developing breast cancer, enriched with women with suspicious lesions on breast MRI which have been recommended for biopsy. Primary Aim: Measure and compare the diagnostic performance of CESM, ABMR, and standard breast MRI, using the following performance measures: cancer detection rate (CDR), biopsy rate, and cancer yield of biopsy (also known as positive predictive value 3 or PPV3). Secondary Aims: Compare screening performance outcome measures of sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) for CESM, ABMR, and standard breast MRI. This will determine the feasibility of each modality as an alternative to standard breast MRI and provide valuable pilot data for designing a larger clinical trial to evaluate non-inferiority of either or both modalities. Breast cancer characteristics (size, histologic subtype, node-positivity, AJCC stage) will be assessed in the overall cohort, and stratified by mode of detection for each modality(screen-detected versus interval).

The association between radiation exposure and cardiac disease is well recognized, it is not fully understood if there exists an optimal or "safe" radiation dose-volume relationship.
