Filter by:HER2 gene amplification increases VEGF production in breast cancers; combined inhibition of HER2 and VEGF enhances response in xenograft models. The upregulation of VEGF in HER2-overexpressing breast cancers may contribute to the aggressive phenotype observed in HER2-positive breast cancer. New therapeutics targeting VEGF and/or its receptors may enhance the efficacy of trastuzumab monotherapy. This trial will investigate the safety and efficacy of combined HER2 and VEGF inhibition.
This study is to explore the feasibility of an alternative dose of dexamethasone pre-medication in older breast and lung cancer patients who are receiving weekly docetaxel chemotherapy.
Breast conservation therapy (BCT) is now widely accepted as a treatment option for most women with Stage I and II invasive breast cancer and most patients with ductal carcinoma in situ (DCIS). Despite superior cosmetic outcome, BCT is more complex and requires a protracted treatment regimen comprised of 6 weeks of daily external beam radiation therapy to the whole breast. The purpose of this study is to determine if an acceptable outcome can be achieved with radiation delivered only to the region of the tumor bed. If this is true, partial breast irradiation may lend itself to much shorter treatment times (one week) and the toxicities to adjacent normal structures (heart, lung, chest wall) will be greatly reduced.
This randomized phase III trial is studying surgery and axillary lymph node dissection to evaluate if systematic axillary node clearance can be avoided in locoregional treatment for operable breast cancer smaller than 10 mm among menopausal women older than 50
The purpose of this study is to determine if acupuncture is effective in relieving hot flashes in women treated with hormonal therapy for breast cancer.
The researchers want to learn whether ZD1839 can improve the activity of tamoxifen, a drug that participants will receive for the treatment of the type of breast cancer being studied. Tamoxifen medicine is part of the standard treatment for the type of breast cancer being studied. It is approved for the treatment of this problem. In order to help the researchers understand how the cancer responds to these medicines, the researchers will take a small tissue sample (biopsy) of the breast cancer before beginning treatment and after two weeks of treatment, at 6 weeks and when surgery is done as part of treatment for the cancer. If participants do not respond to treatment, another biopsy will be done to see why the participants did not respond. These samples will also be collected to look at different characteristics of the cancer. The researchers cannot and do not guarantee that participants will benefit if they take part in this study
We, the investigators at Baylor Breast Care Cancer, are doing this study to learn how well Taxotere makes tumors become smaller. We are also doing this study to find out how well Taxotere treats the type of breast cancer that some patients have. We are asking patients to take part in this study because they have locally advanced breast cancer. Women with this breast cancer will usually receive chemotherapy medicines to reduce or shrink the cancer before surgery to take out the cancer. If patients choose to take part in this study, they will receive Taxotere and the combination of cyclophosphamide and doxorubicin. These medicines are part of the standard good medical care for this type of breast cancer. They are approved for the treatment of this problem. To help us learn how the patients' cancer responds to these medicines, we will take a small tissue sample (biopsy) of the patients' breast cancer before beginning treatment, one day after the first dose of treatment, once each week for the first three weeks of treatment, and when surgery is done as part of treatment for their cancer. These samples will be collected also to look at the biology of the patients' cancer. We will also use a new method called cDNA array technology, which lets us look at thousands of genes (coding information inside the cancer cell) at once. By looking at different genes in the breast cancer, we may learn important information about which cancers will respond to a chemotherapy medicine. We hope to learn if there are different gene patterns in patients whose tumors shrink or do not shrink with this chemotherapy medicine. This information may help us, in the future, to choose the right medicines for women with breast cancer so that they have the highest chance of their cancer shrinking with chemotherapy medicine. We cannot and do not know if patients will benefit if they take part in this study.
The investigators want to know if combining Arimidex and Faslodex with Iressa will be an effective treatment for breast cancer. They also want to know, using special tests on the tumor, the changes that occur with the treatment so they can try to improve their treatment for breast cancer in the future.
Patients with moderate to high risk primary breast cancer (Stage II with more than 4 lymph nodes involved with cancer) III or Stage IV (without evidence of disease) will take tetrathiomolybdate (TM) pills for two years. The objectives of the study are to: - Assess the safety and tolerability of tetrathiomolybdate in patients with breast cancer at high risk of tumor recurrence. - Observe the disease-free survival of patients in this trial. - Conduct background scientific experiments on tumor tissue and blood of patients in this study
One of the basic principles of cancer chemotherapy is that these drugs act exclusively or mainly on cells in cycle. Estrogens have been shown to increase the fraction of breast cancer cells in cycle. Tamoxifen on the other hand, decreases the proliferative fraction and has been shown to negatively impact on the results of adjuvant chemotherapy in breast cancer when given concomitantly. A number of previous studies have attempted estrogenic recruitment of cancer cells (into cell cycle) to increase the efficacy of chemotherapy in locally advanced and metastatic breast cancer. Although some studies showed an increase in response rates in the recruitment arm, there was no benefit in time to progression or survival in any of the studies. These results may have been due to the inadequate sample size of the studies and advanced stage disease (with presumably higher fraction of inherently chemoresistant cells). The present study is designed to test the hypothesis that estrogenic recruitment of micrometastatic disease in operable breast cancer will increase the efficacy of standard adjuvant chemotherapy after surgery. The intervention arm of the study will involve administration of short duration estrogen prior to each cycle of adjuvant chemotherapy. The end-points are disease free and overall survival.
