Active clinical trials for "Breast Neoplasms"

The purpose of this study is to determine whether an experimental alternative imaging method, Near Infrared Spectroscopy (abbreviated as NIR), can be used with a controlled respiratory system to examine the breasts for cancer. The NIR system uses light beams to produce an image or picture of the inside of the breast. The respiratory system will help researchers get more information about the breast tissue by changing the amount of oxygen the tissue receives during NIR imaging.

The goal of this clinical research study is to characterize the 3-dimensional form and mechanical properties of the breast. Researchers want to do this in order to develop new high technology tools for improving the diagnosis and treatment of breast cancer in women.

This trial provides a unique opportunity in that it combines genomic, proteomic and pharmacogenomic assessments in patients receiving chemotherapy for advanced breast cancer. To date no other trials have analyzed gene and protein expression at the same time points in the same patient, combined with clinical outcome. Similar to previous attempts to predict response based on expression of a single gene or protein, we expect that neither genomic or proteomic profiling alone will be sufficient to optimize therapy. Rather, we expect an iterative process that combines information gleaned from both platforms, modified to avoid toxicity based on pharmacogenomics.

This study of hormone positive (estrogen receptor [ER]), metastatic invasive ductal breast cancer looks at functional scanning using positron emission tomography (PET) and patient response to hormone therapy. Functional scans allow investigators to see more than one metastatic location. The investigators will use an estrogen based agent (FES) to see the number of hormone positive metastases and compare that to positive lesions on routine glucose (FDG) based scanning. FES and FDG-PET results will be compared to give a FDG to FES ratio. The PET ratio will be calculated before hormone therapy and at relapse after treatment. The investigators will biopsy an accessible lesion that is FDG positive and FES negative and perform pathological testing for ER and PR positivity and compare it to the original primary tumor ER/PR. The investigators will test the lesion for tumor proliferation (using Ki-67) and aggressiveness using human epidermal growth factor receptor 2 (HER-2). Results will be compared to the primary tumor Ki-67 and HER-2 to determine concordance. The investigators will have pre-treatment results for FES and FDG-PET, will calculate the ratio, and will correlate it to the primary metastatic lesion and test for ER/PR, Ki-67, and HER-2, and subsequent response to therapy. The investigators will determine the FES-PET predictive value for determining appropriateness of hormone therapy for metastatic disease. With these results, the investigators plan to undertake future tumor biomarker/PET studies in metastatic breast cancer.

The purpose of this case collection effort is software design by R2 Technologies, Inc., The information received from Women's Imaging will be provided to the Case Collection, Data Management and Algorithm/software design and development teams who are responsible for the receipt of patient data and management of such data; and creation, testing and validation of R2 Technologies, Inc., for Computer Aided Detection (CAD) and new digital image archiving software design.

Primary Objective: The primary aim of the study is: 1.To identify and validate a panel of molecular and cytogenetic biomarkers able to predict Durable Complete Response (DCR) after chemotherapy and trastuzumab in patients with HER2-positive locally advanced or metastatic breast cancer. Secondary Objective: The secondary aims of the study are: To perform a comprehensive exploration of the molecular and cytogenetic characteristics of DCR patients to identify any possible correlation between the tumour's biological and cytogenetic characteristics and the degree of clinical response to trastuzumab; To produce data in preparation for further translational studies on HER2-positive breast cancer.

This is a feasibility study to demonstrate the team's ability to collect bone marrow aspirates and biopsies for research purposes from women with metastatic breast cancer.

Pilot study using [18F]ISO-1 PET/CT to image sigma-2 receptor binding in metastatic breast cancer. Correlate baseline uptake and change in uptake after therapy with time to progression and standard and experimental pathology assays of biopsy or surgical tissue. The target population is up to 30 adult patients at least 18 years, with at least one site of disease outside the liver by at least one type of standard imaging.

This study will formally address the hypothesis that FES-PET/CT measurement of ER expression predicts clinical benefit of first-line endocrine therapy in newly diagnosed ER+ metastatic breast cancer patients and establishes the repeatability of FES PET/CT.

The purpose of this study is to evaluate the impact of using EndoPredict® clinically to inform treatment decisions for extended endocrine therapy, and the subsequent impact on patient outcomes.
