Filter by:RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving tamoxifen alone is more effective in treating breast cancer than giving tamoxifen together with chemotherapy or after chemotherapy. PURPOSE: This randomized phase III trial is studying giving tamoxifen with or without combination chemotherapy to compare how well they work in treating postmenopausal women who have undergone surgery for breast cancer.
This randomized study will compare maintenance therapy with Avastin (bevacizumab) + Xeloda (capecitabine) versus Avastin alone, in patients with HER2-negative metastatic breast cancer who have not progressed during first-line therapy with docetaxel + Avastin. Eligible patients will receive up to 6 x 3 week cycles of treatment with Avastin (15 mg/mg IV on Day 1 of each cycle) + docetaxel (75-100 mg/m2 IV on Day 1 of each cycle). Those patients who do not progress will be randomized to 3 week cycles of either a) Avastin (15 mg/kg IV on Day 1 of each cycle) + Xeloda (1000 mg/m2 po bid on Days 1-14 of each cycle) or b) Avastin alone. Study treatment will continue until disease progression, unacceptable toxicity, patient request for withdrawal or end of study, and the target sample size is 100-500 individuals.
The purpose of this study is to evaluate in a randomized controlled trail, an innovative cancer communication strategy to help African American breast cancer patients cope with a variety of challenges during and after treatment and to better adhere to recommended treatment guidelines and follow-up care.
Objectives: - To find out the maximum tolerated dose of the GI-6207 vaccine (the highest dose that does not cause unacceptable side effects), and to evaluate any side effects. - To see if GI-6207 has any effect on patients tumors. - To learn how the vaccine causes immune responses against the cancer. Eligibility: - Patients 18 years of age and older who have been diagnosed with a cancer that has not responded to standard treatments. Patients must not be allergic to yeast or yeast products. Design: - Initial physical examination, blood and tissue sampling, computed tomography (CT) scan, and skin test to determine eligibility for the procedure. - Treatment with GI-6027 in seven 14-day cycles as follows: - Vaccine administered on days 1, 15, 29, 43, 57, 71, and 85. - Vaccine given at four sites around the body: right and left chest area below the armpit, and right and left upper thigh in the pelvic region. (These areas drain into parts of your body that contain large numbers of lymph nodes. The lymph nodes contain immune cells that may be activated by the vaccine to target cancer cells.) - Clinic visits for physical examinations to check vital signs, take additional blood and urine samples, and perform other tests needed for the study. - After day 85 (about 3 months), patients will continue to receive vaccine monthly (or every 28 days) as long as the vaccine is not producing harmful effects or side effects and the cancer is either stable or reducing. Patients who do well on the vaccine may continue to receive it for as long as it is available.
Breast radiation treatment is planned from a Computed Tomography (CT) scan. This study is designed to investigate a method to reduce the time between the planning of radiation treatment and its actual start by automating the intensity-modulated radiation therapy (IMRT) planning process. The investigators plan to examine data from another scan called Cone Beam Computed Tomography (CBCT). A CBCT scan provides similar information to a conventional CT scan, however the images for CBCT are acquired at the treatment unit (linear accelerator used for treatment). Using these x-ray pictures of patients, the study team consisting of a radiation oncologist, a medical physicist and a radiation therapist will create a custom treatment plan unique to each patient. By doing this, the investigators hope to reduce the amount of time spent waiting for treatment and the number of hospital visits for patients in the future.
Background: - Dimethane sulfonate (DMS612) is an investigational drug that is being administered to humans for the first time in people with advanced tumors. More information on the maximum tolerated dose of DMS612 will help researchers identify whether the drug is suitable for use in treating certain kinds of cancer, particularly renal cell carcinoma. Objectives: - To determine the maximum tolerated dose of DMS612 (the highest dose that does not cause unacceptable side effects) and evaluate any side effects. - To see if DMS612 has any effect on patients tumors through blood tests and laboratory studies. - To learn how the body processes DMS612. Eligibility: - Patients 18 years of age and older who have been diagnosed with cancer that has not responded well to standard treatments. Design: - Pre-treatment evaluation visit to determine eligibility: - Physical examination - Blood and urine tests - Chest X-ray; electrocardiogram; CAT scan of chest, abdomen, pelvis, and other areas of the body if needed - Other possible tests, such as magnetic resonance imaging (MRI) or positron emission tomography (PET) - Patients will receive one dose of DMS612 by intravenous infusion once a week for 3 weeks, followed by 1 week without the drug. Doses will be adjusted based on possible side effects and cancer response. The disease will be evaluated after three cycles of the drug. - Evaluations during the treatment period: - Physical examination and reviews of side effects. - Blood draws to evaluate the effectiveness of the drug, and how it is processed by the body. - CAT scan at the end of every two cycles (every 8 weeks). - Other scans and imaging procedures as required by the study doctors.
Background: - Research suggests that breast cancers may arise from a population of stem cells in the normal mammary gland that produce clones of cancer cells. - Researchers are now trying to determine what events may initiate the formation of cancer cells. Objectives: - To look for and describe breast stem cells from normal breast tissue from women who do not have breast cancer. - To compare the breast stem cells between women at increased risk for breast cancer and women at average risk for breast cancer. - To show a relationship between the number and type of breast stem cells with the density (appearance) of the mammogram (breast x-ray). - To make cell cultures (grow cells under controlled conditions) from the breast stem cells. Eligibility: -Women 18 years of age and older who are at average or increased risk for breast cancer. Design: Participants complete a health history questionnaire, family history questionnaire and risk assessment questionnaire. - Participants have a mammogram and breast biopsy (surgical removal of a sample of breast tissue). - Women who can become pregnant have a urine pregnancy test....
Background: - Blister fluid contains many of the same biomarkers (substances that can be used to determine the effects of certain kinds of treatments) as blood and urine samples, particularly regarding changes in the skin. - The Radiation Oncology Branch and others are conducting research studies that require blood and urine samples from healthy volunteers and from patients with cancer. In addition to these samples, researchers would like to collect the fluid from blisters to examine markers of inflammation in the skin. Objectives: - To compare blood, urine, and blister fluid samples of patients with cancer who are undergoing radiation therapy to that of volunteers without cancer who will not be receiving radiation therapy. - To gather more information about the effects of radiation therapy on the skin and body fluids of individuals. Eligibility: - Patients 18 years of age and older who will be receiving radiation therapy for either breast or prostate cancer. - A separate group of healthy volunteers will also participate in this study. Design: - Physical examination and blood samples to determine eligibility for the study. - Blister induction, conducted before the start of radiation treatment, at completion of radiotherapy (last day of treatment), and at a visit 12 months after the end of radiation treatment. - Blisters will be created through the use of a suction blister device on the hip (for patients with prostate cancer) or on the treated breast or location of removed breast (for patients with breast cancer). - Blisters will take approximately 30 minutes to form, and fluid will be removed with a needle and syringe. - Blood and urine samples will also be collected at this time. - Radiation treatment for breast or prostate cancer will be conducted according to standard procedures, or as directed by a separate research protocol. - Evaluations during the treatment period: - Physical examination, including vital signs and body weight checks, and pregnancy test for women who can become pregnant. - Blood and urine tests. - Disease evaluation. - Post-treatment evaluations: - Clinic visits at months 1, 3, 6, 9, and 12 after the end of radiation therapy for physical examination and disease assessment. - Study will end 1 year after the final radiation treatment, upon the collection of the final (third) blister fluid sample.
25 patients, treated by brachytherapy in a phase II study "Mammosite" (from 2003 to 2005), will be asked to attend a clinical exam in order to evaluate the late cutaneous toxicity due to brachytherapy. During this consultation, a blood sample will be taken for analysis ( rate of CD8 T-Lymphocyte Apoptosis)
The purpose of this study is to determine whether neo-adjuvant weekly paclitaxel with carboplatin is better than paclitaxel alone in efficiency and safety in early breast cancer, and to explore whether ultrasound and magnetic resonance imaging can predict the efficiency of neo-adjuvant chemotherapy.
