Filter by:Background: - Breast cancer is the most common malignancy in women, occurring in over 230,000 women annually in the United States. - The vast majority of breast cancers originate in the single layer of epithelial cells that line the ductal/lobular system of the breast milk ducts. The premalignant changes which occur in the transformed epithelium are not well understood, however several cytologic or histologic changes have been identified which are associated with an increased risk for breast cancer, including ductal or lobular hyperplasia, hyperplasia with atypia, and lobular or ductal carcinoma in situ. - The identification of cytological or histological abnormalities in breast epithelial cells is an important component of risk assessment. Objective: Primary objectives are: - To determine the incidence and nature of cytologic changes in ductal epithelial cells from the high-risk breast, in specimens collected by breast ductal lavage, and to determine if these cytologic findings are different from those of female normal volunteers not at increased risk for breast cancer. - To characterize by breast duct endoscopy, high risk breast ductal epithelium and architecture, and correlate these findings with the cytologic findings referenced in above bullet. - To determine what is the global gene expression pattern of high risk breast epithelial cells from the high risk breast, and does this differ from that of breast epithelial cells from female normal volunteersnot at increased risk for breast cancer. The gene expression profile will be determined by cDNA microarray and validated by RT-PCR. Eligibility: Eligibility for high risk individuals will include: - Women with a unilateral invasive or noninvasive (DCIS) breast cancer of epithelial origin. - Women without breast cancer, but with a Gail Index greater than 1.67 percent, or a cumulative lifetime risk greater than or equal to double the age- and race-matched general population risk. - Women known to be BRCA1/2 or other hereditary genes mutation carriers. - Women with cytologic or histologic evidence of ductal hyperplasia, atypical ductal hyperplasia, or lobular carcinoma in situ. - Women may be either premenopausal or postmenopausal. Postmenopausal is defined by the absence of menstrual periods for at least 12 months. - Postmenopausal women who have previously undergone a hysterectomy without oophorectomy must have a serum FSH level of > 40 IU/ml, and a serum estradiol level of less than40 pg/ml to document postmenopausal status. Eligibility for normal volunteers will include: - Women who are premenopausal or postmenopausal with a Gail model risk index less than 1.67 percent, and without a cumulative lifetime risk greater than or equal to double the age- and racematched general population risk. - Women who have previously undergone a hysterectomy without oophorectomy must have a serum FSH level of >40 IU/ml, and a serum estradiol level of less than 40 pg/ml to document postmenopausal status. - Both breasts must be free of any suspicious areas by physical examination and, for women over 30 years of age by mammogram. There must be no history of atypical hyperplasia, invasive or in situ carcinoma. Both groups must have acceptable white blood cell and platelet counts. Design: Breast ductal epithelial cells will be collected by breast ductal lavage from (a) the breast in women at increased risk for breast cancer, and (b) the breast of female normal volunteers who are not at increased risk for breast cancer. Ductal epithelial cell specimens will be analyzed cytologically for the presence of hyperplasia, atypia, or in situ changes. Breast duct endoscopy will be performed in breast cancer patients and in normal volunteers with cytologic atypia on ductal lavage to determine ductal architectural changes associated with increased risk for breast cancer, and to provide correlation with cytologic atypia. The gene expression profile of normal and high-risk ductal epithelial cells will be studied by cDNA-microarray to determine changes in gene expression associated with increased risk for breast cancer. Additional molecular profiling experiments which will be performed as lavage cells are available include DNA whole exome sequencing, Comparative Genomic Hybridization (CGH), proteomic tissue lysate arrays, and identification of mammary stem cells. A total of 104 high-risk subjects and 110 normal volunteers will be studied, divided approximately evenly between premenopausal and postmenopausal women....
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of combining liposomal doxorubicin with gemcitabine in treating women who have metastatic breast cancer.
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or deliver cancer-killing substances to them. Combining chemotherapy with monoclonal antibody therapy may kill more tumor cells. PURPOSE: This randomized phase II trial is to see if docetaxel with or without bevacizumab followed by surgery, radiation therapy, and combination chemotherapy works better in treating patients who have stage III or stage IV breast cancer.
RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining different types of biological therapies may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining different biological therapies in treating women who have stage IV breast cancer.
Description: The trial is designed to determine the response of the immune system of patients with breast cancer to a vaccine made from their own tumor. Researchers believe that this particular vaccine, which is made from purified heat shock proteins taken from each patient's tumor, might alert the body's immune system to recognize and attack invading cancer. To be considered potentially eligible for this study you must be a high risk breast cancer patient and have a tumor that can be removed surgically. Length/Duration: Vaccinations are administered weekly for six weeks. Follow up visits to the clinic are every three months for two years, then every six months thereafter.
This study will examine the frequency and severity of problems in women with breast cancer for 2 years following initial medical treatment, including: - Physical impairments, such as loss of strength or flexibility, increased weight and swelling. - Symptom distress, such as pain, fatigue and weakness. - Functional limitations and disabilities, such as loss of independence in activities of daily living (e.g., grooming, bathing, dressing, driving a car), work and social and recreational activities. It will identify factors associated with these problems and try to determine their relationship to them. Patients 18 years of age and older with stage I, II, III or IV breast cancer may be eligible for this study. Women who have a breast biopsy negative for cancer will also be enrolled as control subjects. Participants will be drawn from patients referred to the National Naval Medical Center for diagnosis and treatment during 2001-2003. Participants will be evaluated over a 2-year period during an initial baseline visit (before medical treatment or biopsy) and follow-up visits at 1, 3, 6, 12, 18 and 24 months following procedures: - Interview about past medical history and present illness, social and recreational activities, functional independence at work and during activities of daily living. - Completion of questionnaires including health survey, upper limb disability questionnaire, and physical activity questionnaire. (Questionnaires are completed only at baseline and 12 and 24 months after medical treatment begins.) The questionnaires take about 30 to 40 minutes to complete. - Upper body examination, including pain measurement using a 10-point scale, active and passive range of motion measures, manual muscle testing measures using a 10-point scale, timed upper limb lift test, and measures of upper limb volume and girth.
This study will examine the frequency and severity of problems in women with breast cancer during the first year after initial medical treatment, including: - Physical impairments, such as loss of strength or flexibility, increased weight and swelling - Symptom distress, such as pain, fatigue and weakness. - Functional limitations and disabilities, such as loss of independence in activities of daily living (e.g., grooming, bathing, dressing, driving a car), work and social and recreational activities. It will identify factors associated with these problems and try to determine their relationship to them. Patients 18 years of age and older with stage I, II, III or IV breast cancer may be eligible for this study. Participants will be drawn from patients referred to the National Naval Medical Center for diagnosis and treatment during 2000-20001. Participants will be interviewed and their medical records reviewed for past medical history, history of the present illness and social and recreational history. They will be seen five times over a 1-year period (initial visit and at 3, 6, 9, and 12 months), for 30-minute visits, which will include the following: - Interview about past medical history and present illness, social and recreational activities, functional independence at work and during activities of daily living. - Complete health survey and upper limb disability questionnaire; physical activity questionnaire to be completed at 6 and 12 months after medical treatment begins. The questionnaires take about 30 to 40 minutes to complete. - Upper body examination, including pain measurement using a 10-point scale, an upper limb lift test, and measures of upper limb volume and girth.
This study will examine how the body handles etoposide, a drug used to treat breast cancer. The knowledge gained may lead to more effective use of the drug with fewer side effects in the future. Breast cancer patients who are receiving etoposide as part of their treatment may participate in this study. Patients will have 18 blood samples (about a teaspoon or less each) drawn over a 72-hour period during and after their infusion of etoposide. The initial blood samples cannot be taken from the same intravenous line (small tube placed in a vein) used to deliver the etoposide, so a second line may have to be placed temporarily to obtain these samples.
RATIONALE: It is not yet known which combination of surgeries is more effective in reducing side effects and improving recovery in treating breast cancer. PURPOSE: This randomized phase III trial is comparing how well axillary lymph node dissection with either mastectomy or excisional biopsy plus radiation therapy works in treating women with stage I or stage II breast cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Randomized phase II trial to compare the effectiveness of two different doses of capecitabine in treating women who have advanced or metastatic breast cancer.
