Filter by:The purpose of this study is to learn about the effects of stress on hormones, the relationship between these hormones and cancer progression.
The purpose of this study is to determine whether a new surgical technique (radioguided seed localization) for localizing nonpalpable breast tumours is better than the standard technique (needle localization).
Two thirds or more of breast cancers are dependent on estrogen for growth. We use a number of estrogen-blocking medicines for treatment of metastatic breast cancer. The treatment response to these agents is unpredictable, however, and approximately one-third of patients with metastatic breast cancer with receptors for estrogen or progesterone have no benefit from hormonal therapy. Nearly all patients with metastatic breast cancer will eventually become resistant to hormonal therapy despite the fact that the hormone receptors are still present. Some cells make a different class of growth factor receptor called the Epidermal Growth Factor Receptor. There is a growing body of experimental evidence showing that breast cancer cells that make Epidermal Growth Factor Receptors are more resistant to hormonal therapy and have a poorer prognosis. Several investigators have found that the Epidermal Growth Factor Receptor can activate the estrogen receptor, even in the presence of estrogen-blocking drugs. Growth of these cells can be slowed by blockade of both Epidermal Growth Factor Receptor signaling and estrogen-receptor signaling. Lapatinib is a small molecule which can inhibit two different forms of the Epidermal Growth Factor Receptor. It has been studied in people with a number of different cancers, including breast cancer, and a safe dose and its common side effects have been defined. Our hypothesis is that the Epidermal Growth Factor Receptor is the dominant receptor pathway used by breast cancers in our patients with hormone-resistant tumors. Drugs like lapatinib which block several forms of the Epidermal Growth Factor Receptor would best be able to reverse resistance to hormonal agents.
In this phase II study, we plan to evaluate the efficacy, safety and tolerability of weekly docetaxel and capecitabine on a 21-day cycle followed by maintenance single agent capecitabine for the treatment of metastatic breast cancer, Based on the efficacy and toxicity of the combination regimen dosages previously reviewed; weekly docetaxel 30mg/m2 on days 1 and 8 plus capecitabine 1600mg/m2 (800mg/m2 orally twice daily)on day 1 through 14 of each cycle will be utilized.
Over 30 studies have shown that exercise can improve physical fitness, reduce fatigue, increase functioning, and enhance overall quality of life (QoL) in breast cancer survivors both during and after treatments. Research has also shown, however, that breast cancer survivors experience a significant reduction in physical activity during treatments that is not recovered even years after treatments are completed. The objectives of this study are to examine the effects of two behavior change interventions (a step pedometer and printed materials) on physical activity, social cognitive variables, and QoL in a population-based sample of breast cancer survivors. Approximately 300 breast cancer survivors living in Northern Alberta will be randomized to one of four groups: (1) an exercise recommendation only group (viewed as the current standard of care), (2) an exercise recommendation plus pedometer group, (3) an exercise recommendation plus printed materials group, and (4) an exercise recommendation plus pedometer and printed materials group. Our primary hypothesis is that participants receiving the combined pedometer and printed materials intervention will report the greatest change in physical activity. Our secondary hypotheses are that these interventions will also result in improved QoL and more positive social cognitive beliefs about exercise in breast cancer survivors. Given the geographic dispersion of our population, finding practical and sustainable interventions that employ distance medicine-based approaches may be ideal for promoting healthy activity patterns in breast cancer survivors in Northern Alberta.
The purpose of this study is to determine whether women with primary breast cancer who were randomly assigned to receive a brief group therapy would show a greater reduction in mood disturbance over time compared to those randomized to the control condition. We also hypothesized that women who were highly distressed at baseline would show the greatest benefit from participating in a support group, and that therapists with more training and experience would be most effective in reducing distress.
The study hypothesis is that the addition of Mycograb to docetaxel will improve outcome in advanced carcinoma of the breast.
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by stopping blood flow to the tumor. It is not yet known whether giving docetaxel together with bevacizumab is more effective than docetaxel alone in treating breast cancer. PURPOSE: This randomized phase II trial is studying how well giving docetaxel together with bevacizumab works compared to docetaxel alone as first-line therapy in treating women with stage IV breast cancer.
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.
Sorafenib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. Estradiol can cause the growth of breast cancer. Hormone therapy using anastrozole may fight breast cancer by blocking the use of estradiol by the tumor cells. Sometimes when hormone therapy is given, it does not stop the growth of tumor cells. The tumor is said to be resistant to hormone therapy. Giving sorafenib together with anastrozole may reduce drug resistance and allow the tumor cells to be killed. This phase I/II trial is studying the side effects and best dose of sorafenib when given in combination with anastrozole and to see how well they work in treating postmenopausal women with metastatic breast cancer.
