NCT00002564
RATIONALE: Dietary fat may be involved in the growth of cancer cells. Restricting dietary fat may help fight cancer. PURPOSE: Randomized clinical trial to study the effectiveness of a low fat diet in treating postmenopausal women who have stage I, stage II, or stage IIIA breast cancer that has been completely removed by surgery.
NCT00691119
The purpose of this study is to find out if it is possible to study relaxation and visualization therapy (RVT) with individuals that have breast cancer. We will also look at what effects, the good and bad, RVT has when used with radiation therapy. We are interested in how RVT may relate to energy, quality of life, stress, and the immune system. Relaxation and Visualization therapy will lead participants through a practice of physical relaxation and then a step by step visualization. In this study, participants will be led through an RVT exercise, providing an interactive process. In addition, women will perform solitary RVT exercises at home on weekends. Participants for this study will be drawn from two OHSU physicians' regular patient base. To be sure that we are testing the effects of RVT alone, we will use three groups. The three groups will be RVT, education, and a control. The RVT group will receive RVT with radiation, and the education group will receive breast cancer related health education with radiation. The third group will receive no treatment beyond radiation. This third group is called the control. The entire study will last for approximately twelve weeks. For the first 6 weeks, each participant will be receiving radiation therapy. We will be particularly interested in the effects that RVT may have on energy, quality of life, stress, and the immune system. No experimental drug or device will be used during the study.
NCT00015938
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combining docetaxel, vinorelbine, and filgrastim in treating women who have stage IV breast cancer.
NCT00016406
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether combination chemotherapy is more effective with or without filgrastim in treating breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combining doxorubicin, cyclophosphamide, and paclitaxel with or without filgrastim in treating women who have inflammatory or locally advanced breast cancer.
NCT00002920
RATIONALE: It is not yet known whether medroxyprogesterone is effective in preventing endometrial disorder in patients with breast cancer who are taking tamoxifen. PURPOSE: Randomized phase III trial to study the effectiveness of medroxyprogesterone in preventing endometrial disorder in postmenopausal women who have ductal carcinoma in situ, lobular carcinoma in situ, Paget's disease of the nipple, stage I breast cancer, or stage II breast cancer and who are taking tamoxifen.
NCT00031811
RATIONALE: Raloxifene and exercise may improve bone health and quality of life in breast cancer survivors. Assessing bone health and quality of life may improve the ability to plan treatment. PURPOSE: Randomized clinical trial to study the effectiveness of raloxifene with or without exercise compared with exercise alone in women who have been previously treated for breast cancer.
NCT00657137
This study will compare the anti-tumor efficacy of apricoxib and lapatinib/capecitabine with placebo and lapatinib/capecitabine as measured by time to disease progression and evaluate urinary PGE-M measurements or baseline COX-2 expression in tumor tissue by IHC as a surrogate selection criterion for patients who will benefit from future treatment with apricoxib.
NCT00002646
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Combining chemotherapy with hormone therapy may kill more tumor cells. Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of fenretinide may be an effective way to prevent the recurrence of breast cancer. It is not yet known whether tamoxifen plus fenretinide is more effective than tamoxifen alone for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen plus fenretinide with tamoxifen alone in treating postmenopausal women who have stage II or stage III breast cancer that is estrogen receptor positive and/or progesterone receptor positive.
NCT00540358
The purpose of this clinical trial was to determine whether combining iniparib (BSI-201) with standard chemotherapy in estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancer patients improve clinical benefit compared to treatment with standard chemotherapy alone. Based on data generated by BiPar/Sanofi, it was concluded that iniparib does not possess characteristics typical of the poly (ADP-ribose) polymerase (PARP) inhibitor class. The exact mechanism has not yet been fully elucidated, however based on experiments on tumor cells performed in the laboratory, iniparib is a novel investigational anti-cancer agent that induces gamma-H2AX (a marker of DNA damage) in tumor cell lines, induces cell cycle arrest in the G2/M phase in tumor cell lines, and potentiates the cell cycle effects of DNA damaging modalities in tumor cell lines. Investigations into potential targets of iniparib and its metabolites are ongoing.
NCT00036985
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Microwave thermotherapy kills tumor cells by heating them to several degrees above body temperature. Combining chemotherapy with microwave thermotherapy before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Randomized phase II trial to compare the effectiveness of combination chemotherapy with or without microwave thermotherapy before surgery in treating women who have locally advanced breast cancer.
NCT00036998
RATIONALE: Microwave thermotherapy kills tumor cells by heating them to several degrees above body temperature. PURPOSE: Randomized phase II trial to compare the effectiveness of microwave thermotherapy before surgery to that of surgery alone in treating women who have stage I or stage II breast cancer.
NCT00083304
RSR13 (efaproxiral) is a radiation sensitizer that has shown positive results in a Phase 3, randomized clinical trial of patients with brain metastases. Of 111 eligible breast cancer patients with brain metastases in that trial, 59 patients who received RSR13 prior to radiation therapy had a median survival time that was twice as long as the 52 patients who did not receive RSR13 prior to radiation therapy. RSR13 (efaproxiral) is an experimental drug that increases the amount of oxygen released from blood into the tissues. It is well known that certain types of cancer tumors, including those in brain metastases, lack oxygen. Lack of oxygen in a tumor can reduce the effect of radiation therapy (RT). RSR13 may increase the oxygen level in brain tumors so that radiation therapy works better. This study will enroll up to 360 women with brain metastases from breast cancer, and will evaluate if whole brain radiation therapy given with RSR13 will have a better treatment effect than whole brain radiation therapy alone. RSR13 will be infused intravenously (IV) through a central catheter placed in a central vein. Women randomized (assigned) to receive RSR13, therefore, will need to have a central catheter placed for treatment unless one is already in place.
NCT01108315
Cancer symptoms due to disease progression or side effects caused by cancer treatment are prevalent. Most cancer patients are treated in outpatient settings. Patients may be provided with patient education materials and counseled on anticipated side effects while being provided with different self-management options and warnings regarding when medical care is required. Despite these efforts, many people feel set adrift in having to self-manage treatment and illness related symptoms at home resulting in a sense of burden for the patient and the caregiver. When the patient does visit the doctor, they increasingly are asked questions to elicit information about symptoms and performance using structured questionnaires that are shown to give reproducible, meaningful, quantitative assessments of how patients feel and how they function-measures that are called patient reported outcomes or PROs. The questionnaires used to collect this information are called PRO instruments. The use of PRO instruments is part of a general movement toward the idea that the patient, properly queried, is the best source of information about how he or she feels. The goal of using PRO measures is to provide better information to doctors and patients so that the best treatment for patients can be determined. PURPOSE: To reduce the isolation of patients/caregivers from the medical care team and to improve patient/provider communication and clinical decisions by keeping documented daily reports of patient symptoms online, having notifications sent to the medical team of moderate to severe symptoms and by reviewing these reports at clinic visits with the medical staff.
NCT00022672
This 2 arm study assessed the safety and efficacy of adding intravenous trastuzumab (Herceptin®) to daily oral anastrozole (Arimidex®) tablets as first- and second-line treatment in postmenopausal patients with human epidermal growth factor receptor-2 (HER2) overexpressing metastatic breast cancer (ER+ve and/or PR+ve). Patients were randomized to receive either anastrazole 1 mg per os (po) daily, or anastrazole 1 mg po daily + a loading dose of Herceptin® 4 mg/kg intravenous (iv) followed by weekly doses of Herceptin® 2 mg/kg iv. The anticipated time on study treatment was until disease progression, and the target sample size was 100-500 individuals.
NCT01537406
The purpose of this study is to evaluate the frequency of chronic breast pain about 8 years after the delivery of the radiation treatment, and to compare the frequency between subjects that received breast Intensity-Modulated Radiation Therapy (IMRT) and those that received standard wedge radiotherapy. The cosmetic result, meaning how similar is the treated breast compared to the non-treated breast, will be assessed. Also, the occurrence of delayed radiation treatment side effects including tiny red vessels in the skin, breast indurations (hardening of the skin), skin discoloration, oedema (swelling of the breast), and skin dryness will be captured.
NCT00077857
This 2 arm study compared the efficacy and safety of label dose of capecitabine (Xeloda®) to that of a lower dose of Xeloda® plus docetaxel (Taxotere®) in patients with locally advanced or metastatic breast cancer after failure of chemotherapy with an anthracycline. Patients were randomized to receive either 1250 mg/m\^2 or 825 mg/m\^2 orally twice a day (po bid) on days 1-14 of each 3 week cycle, in combination with Taxotere® 75 mg/m2 intravenous (iv) on day 1 of each 3 week cycle. The anticipated time on study treatment was until disease progression and the target sample size was 440 individuals.
NCT00811369
The purpose of this study is to evaluate whether the combination of fulvestrant and ZACTIMA, versus fulvestrant plus placebo, results in a significant decrease in the bone marker, urinary N-Telopeptide (NTx) in postmenopausal women with bone only, or bone predominant, hormone receptor-positive metastatic breast cancer. A significant decrease will be defined as a \> 30% reduction in urinary NTx level from baseline.
NCT01038804
The purpose of this study is to evaluate survival, response rate, safety and tolerability of YM155 given in combination with docetaxel as first-line treatment in subjects with human epidermal growth factor 2 non-overexpressing (HER2 negative) metastatic breast cancer.
NCT00043017
RATIONALE: Diagnostic procedures such as magnetic resonance imaging (MRI) may help determine the effectiveness of chemotherapy in killing breast cancer and allow doctors to plan more effective treatment. PURPOSE: Diagnostic trial to study the effectiveness of MRI in monitoring tumor response in women who are receiving chemotherapy for stage III breast cancer.
NCT00003992
Randomized phase II trial to study the effectiveness of chemotherapy with paclitaxel and the monoclonal antibody trastuzumab followed by chemotherapy in treating women who have stage II or stage IIIA breast cancer that overexpresses HER2. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may kill more tumor cells.
