Active clinical trials for "Breast Neoplasms"

The purpose of this study is to describe adherence to anastrozole treatment current practice: cases where anastrozole treatment was halted ( timescale and causes) and estimate the proportion of postmenopausal women with early breast cancer who continue anastrozole therapy after one year follow-up.

The purpose of this study is to establish feasiblity of recruiting obese breast cancer survivors at the end of treatment, getting those survivors to lose weight and attend follow-up visits for 6 months.

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.

The purpose of this study is to identify novel genetic factors which distinguish breast cancer in younger women compared to older women. By identifying these novel genetic factors we believe more specific therapies can be developed and breast cancer may be prevented among women with an increased cancer risk. A woman does not have to live in St. Louis to participate.

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.

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.

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.

By using gene-expression profiling, Van't Veer and colleagues developed a 70-gene prognosis profile, MammaPrint, to identify breast cancer patients who are at low risk of developing distant metastases and therefore might safely be spared chemotherapy. The aim of this study is to evaluate the prognostic value of the 70-gene Mammaprint profile in Japanese women with node-negative breast cancer.

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.
