Active clinical trials for "Breast Neoplasms"

The purpose of this study is to evaluate a dynamic near infrared imaging device for characterizing suspicious breast lesions

The purpose of this trial is to collect plasma, serum, whole blood and tissue samples from women with breast cancer and plasma, serum, whole blood from healthy women, which will be made available to researchers for biomarker analysis.

This study aims to evaluate if a light based technique, called Optical Breast Spectroscopy (OBS) formerly known as Transillumination Breast Spectroscopy (TiBS), can be used to detect differences in breast tissue between high- and low-risk populations and within the high-risk population between BrCa1 or 2 carriers and non-carriers. These differences may include differences in breast tissue composition and metabolism at time of enrollment into the study (possibly reflecting changes occurring in adolescence) and in the rate of breast tissue change over time (possibly reflecting rate of tissue transformation from normal to ultimately malignant state).

Women with newly diagnosed breast cancer anticipating breast-conserving surgery are enrolled into the study and will undergo both high-resolution positron emission mammographic (PEM) imaging and contrast-enhanced magnetic resonance imaging (MRI) of the breast(s). The purpose of this study is to determine changes in surgical management resulting from PEM or MRI imaging as compared to conventional imaging and to determine if the changes were appropriate with histopathology as gold standard.

Breast cancer patients who diagnosed by core needle biopsy or excisional biopsy underwent CT scan to locate the sentinel lymph node (SLN) before SLN biopsy (SLNB) at the same day of surgery. When CT examination performed, those patients were in supine position, with the arms stretched upward but bent at the elbow with the hands at the side of the cranium which similar to the surgical position. After local anesthesia, 2mL of iopamidol was injected subcutaneously to the peritumoral and peri-areolar areas followed by gentle massage for about 1 minute. Contiguous 2-mm-thick CT images that included the breast and axilla were obtained prior to administration of the contrast agent. After 3D CT reconstruction, the SLN was identified as the most inferiorly visible nodule in the axilla connected to the lymphatic vessel on the CT imaging monitor. A professional intervention doctor punctured the defined lymph node guided by the CT monitor using the Breast Lesion Localization Needles (interv). The needle would stay in the patient's axilla until the surgery. All the lymph nodes including the CT defined one and which marked by methylene blue dye or 99mTc-sulfur colloid tracers were removed, which then would be tested by touch imprint cytology for the intraoperative diagnosis. Patients who had positive SLN would receive axillary dissection. The investigators evaluated the new method by comparing lymph nodes defined by CT and traditional ways.

To assess the quantitative real time PCR results results of oligonucleotide probes for a number of gene transcription products that may be useful as predictors of indicators of response to celecoxib.

One form of breast cancer, known as inflammatory breast cancer (IBC), is characterized by diffuse erythema (redness) and edema (peau d'orange) of the breast. This type of cancer is aggressive and poorly understood. It is rare in the United States (about 4 percent of cases), but more common in Egypt and Tunisia (up to 23 percent of cases). Conducting a case-control study of IBC is complicated by several factors, including the lack of standardized criteria for IBC. In addition, collecting pre-chemotherapy tissue and blood samples from IBC patients is difficult because treatment begins immediately after diagnosis. In this pilot study, the National Cancer Institute will collaborate with two major cancer centers and two hospitals (in Egypt and Tunisia) to determine the feasibility of a case-control study of IBC. The study will assess the number and characteristics of IBC cases, the feasibility of identifying cases at diagnosis, and the availability of control subjects; will collect frozen pre-treatment tumor tissue from five IBC cases to determine whether RNA isolation is possible; will obtain digital photographs of the breasts of IBC cases; and will demonstrate collaboration between the institutions and personnel involved in the study. The study will last for approximately one year. Participating hospitals will identify IBC cases. Consenting patients will undergo a breast examination in which the examining surgeon will complete an Initial Examination Form (IEF). Digital photographs of the breasts (but not face) will be taken and linked to the study ID number. Tissue examination results will be entered into the IEF. For five selected cases, additional pre-treatment tumor tissue will be collected and frozen. This pilot study will assess the availability of controls for a case-control study by investigating the number and type of admissions to the Ear, Nose, and Throat and Ophthalmology Departments at participating hospitals during 2000-2003, using computerized records.

This study will analyze blood samples to identify substances that are associated with the development of breast cancer. It will determine if: Women who are diagnosed with a benign breast condition that is related to a considerably increased risk of breast cancer are more likely to have certain gene variants than women diagnosed with conditions related to very little increased breast cancer risk Women with benign breast conditions who subsequently develop breast cancer are more likely to have certain gene variants than women with similar benign conditions who do not develop breast cancer. This study will examine blood samples from premenopausal women who underwent breast biopsy (removal of a small piece of breast tissue for microscopic examination) at four hospitals in Grand Rapids, MI, from 1977 to 1987 and were found to have benign breast disease. The women, who agreed to participate in a study of markers for breast cancer, also provided a blood sample and were interviewed for information on their breast cancer risk factors, family history of breast cancer, use of medications, and history of medical conditions. This study will retrieve the biopsy reports for these women, determine which of them later developed breast cancer, and perform genotyping on their blood samples. The information from this study may help in future diagnosis and treatment of breast cancer.

To evaluate 1) the extent of patient overestimation of breast cancer development risk in subjects referred to a physician-based high-risk breast clinic; 2) the ability of physician counseling to improve patient risk perception and reduce psychological distress; 3) to identify factors relevant in clinical practice associated with increased distress and risk perception.

This study aims to evaluate if a light based technique, called Transillumination Breast Spectroscopy (TIBS), can be used to construct a non-invasive breast cancer risk predictor which provides a better odds ratio than mammographic parenchymal density.
