Filter by:This is a Phase II, randomised, double-blind, placebo-controlled study. Subjects with histologically-confirmed oestrogen receptor negative (ER-), progesterone receptor negative (PgR-) primary breast cancer breast cancer will be randomly assigned in a 2:1 ratio to receive ZD1839 250 mg once daily or matching placebo for a total period of 5 weeks. Surgical intervention will take place after 4 weeks (on Day 29) and treatment will continue for 1 week after surgery.
RATIONALE: Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase II trial is studying how well vaccine therapy works in treating patients with stage IIIB or stage IV breast cancer in remission.
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using goserelin and anastrozole may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving goserelin together with anastrozole may be an effective treatment for male breast cancer. PURPOSE: This phase II trial is studying how well giving goserelin together with anastrozole works in treating men with recurrent or metastatic breast cancer.
Currently in Canada, and at the Cross Cancer Institute, the treatment of many women with breast cancer involves radiotherapy (RT). There is a complex process which takes place in order to plan the radiation therapy before patients commence their treatment. In many circumstances the investigators use computerized technology to assist in planning their treatment. This allows more precision in delivering the treatment to the desired areas and avoiding areas of normal tissue. Once the planning process is completed, the investigators then place marks with a marker pen on the skin of the patient to outline the area where the radiation will be delivered. The investigators confirm that the correct area is being treated with an x-ray taken on the treatment unit while the patient is in the treatment position. This is called a port film or verification film. The investigators then compare this to what they set up with the computerized data. If all the information matches, the patient is then treated for the full course of radiation, with the assumption that all treatments are given in the correct position. No further routine checking is done. The standard at some radiotherapy centers is that the patient treatment position is verified weekly by a portal film. At the Cross Cancer Institute the investigators normally only do it once at the beginning of treatment. No information is available to confirm the necessity of doing more frequent verification films, but in view of the very complex nature of the investigators' treatment delivery, it may be necessary to confirm the accuracy of their treatment more often. Over the course of a 4-5 week treatment the investigators know that some patients may lose weight, some become more relaxed after a few days, and some have trouble with the movement in their shoulders; all of these factors influence the positioning of the patient. Measurements taken on the treatment unit often change during the course of a patient's treatment, but no further verification is performed to ensure that the treated area is still what was initially intended. It is important from a quality assurance standpoint to see if more frequent checking of the radiation treatment set-up is indicated.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of or treat early cancer. Diagnostic procedures, such as ductal lavage, may improve the ability to assess the effectiveness of chemopreventive drugs, such as tamoxifen, on breast cells and may help doctors plan more effective treatment. PURPOSE: This phase II trial is studying how well ductal lavage works in assessing changes in breast cells in women with early breast cancer or in those at high risk of developing breast cancer who are eligible for tamoxifen therapy.
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase II trial is studying how well arsenic trioxide works in treating women with locally advanced or metastatic breast cancer.
RATIONALE: Drugs used in chemotherapy, such as docetaxel, doxorubicin, and cyclophosphamide, use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them at different times, may kill more tumor cells. It is not yet known which combination chemotherapy regimen is more effective for breast cancer. PURPOSE: Randomized phase I trial to compare the effectiveness of two regimens of docetaxel combined with doxorubicin and cyclophosphamide in treating women who have advanced breast cancer.
RATIONALE: The monoclonal antibody trastuzumab can locate breast cancer cells that have HER2 on their surface and either kill them or deliver tumor-killing substances to them without harming normal cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using exemestane may fight breast cancer by reducing the production of estrogen. Combining trastuzumab with exemestane may be an effective treatment for breast cancer with high amounts of HER2. PURPOSE: Phase II trial to study the effectiveness of combining trastuzumab with exemestane in treating postmenopausal women who have metastatic or locally advanced HER2-positive breast cancer.
RATIONALE: Tipifarnib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining tipifarnib with trastuzumab may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining tipifarnib with trastuzumab in treating patients who have metastatic breast cancer.
RATIONALE: Examining biomarkers in fine-needle aspiration specimens from women at risk for breast cancer may improve the ability to detect breast cancer cells early and plan effective treatment. PURPOSE: Screening trial to compare specific biomarkers based on fine-needle aspiration specimens from women at increased or normal risk of breast cancer.
