Breast cancer is the most common cancer among women in the United States. Breast cancer research has been hampered by the difficulty in collecting normal breast tissue. In this study, researchers will obtain samples of normal breast tissue from organ donors and will collect risk-factor data from next-of-kin. The purpose of this study is to learn how normal breast develops and responds to stresses that are known to increase a woman s chance of developing breast cancer. Following the breast-tissue donation from 20 volunteers, surgical technicians will make small incisions in the skin and tissue of the breast and remove several samples measuring about one-inch. Technicians also will take samples of the uterine lining to estimate the date of the last menstrual period. The tissue will then be sent to the National Cancer Institute for laboratory research studies. Steps will be taken to ensure that the identity of the participants remains confidential.
This study will collect information on the height and weight of women who participated in a 1998 study in Triana, Alabama, on the risk of breast cancer and benign breast disease in relation to environmental exposure to the pesticide DDT and similar chemicals. This additional information is needed to calculate the participants' body mass index (BMI), which is required for completing analysis of the data. The 1998 study-a collaborative effort of the National Cancer Institute, the Triana Area Medical Fund, and the College of Nursing at the University of Alabama at Huntsville-investigated possible effects of DDT and other compounds on the risk of breast cancer, predominantly among African-American women in the area of Triana, Alabama. The study was initiated as a result of medical findings showing high blood levels of DDT among the local population who had consumed fish from a tributary of the Tennessee River that had been polluted by the discharge over several decades of large quantities of pesticides from a DDT production plant. Women participating in the study had a mammogram, physical examination, breast examination, and blood draw, and completed a questionnaire on diet and lifestyle factors. In order to complete analysis of the data and determine whether there is an association between environmental exposure to DDT and related chemicals and breast cancer risk, additional information on BMI is required.
Current standard of care for post-operative analgesia after breast surgery in CDHA is Tylenol #3® (300 mg acetaminophen, 30 mg codeine, 15 mg caffeine per tablet). We are proposing to test the analgesic efficacy of acetaminophen plus ibuprofen against Tylenol #3® in patients undergoing outpatient breast surgery.
Breast nipple aspirate fluids (NAF) are useful for non-invasive monitoring of the breast. NAF has been shown to exhibit large inter-individual differences in lipid peroxidation. Unfortunately, the yield of epithelial cells in NAF is low. More recently, breast ductal lavage has been approved for clinical use. Nuclear morphologic features of breast biopsies have been shown previously to have prognostic value for breast cancer risk. In women without cancer, there may be subtle changes in the breast epithelial cells that can only be defined with computer-assisted measurements. The subjects selected for this study will be 98 women with biopsy-confirmed proliferative breast disease. These women are at slightly increased breast cancer risk, and exhibit higher mean levels of cholesterol and cholesterol oxides in NAF than women with non-proliferative histology in the breast. Levels of 8-isoprostane, cholesterol, fatty acids, fat-soluble micronutrients and 2,6-cyclolycopene-4,5-diol will be quantified in breast NAF that is obtained before breast lavage. These measures were chosen based on their potential relationship to dietary intakes and to oxidative stress, which is relevant to the application of these methods to dietary prevention studies.The investigators will characterize the morphology of breast epithelial cells from lavage using quantitative image cytometry to capture nuclear and cellular area, diameter, roundness, perimeter, and nuclear:cytoplasmic area ratio. Correlations will be evaluated between the measured morphologic features and each analyte in the NAF. The impact of various clinical, demographic and dietary factors on cellular morphology will also be explored. This study will help establish the feasibility of using these measures as endpoints in dietary intervention studies and will generate hypotheses that should be tested in larger studies. Such measures also should be applicable to molecular epidemiological investigations that seek to examine the impact of certain gene polymorphisms and environmental exposures on biomarkers of cancer risk.
The purpose of this study is to test the safety and effectiveness of an investigational chemotherapy agent in patients with advanced breast cancer.
The purpose of this study is to determine whether BNP7787 is effective in preventing or reducing neurotoxicity (nerve damage) caused by paclitaxel (Taxol®).
Phase I trial to study the effectiveness of vaccine therapy with or without sargramostim in treating patients who have advanced or metastatic cancer. Vaccines may make the body build an immune response to kill tumor cells. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood. Combining vaccine therapy with sargramostim may make tumor cells more sensitive to the vaccine and may kill more tumor cells
