Filter by: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.
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.
In vitro data suggest synergy between oxaliplatin and 5-FU. The combination of oxaliplatin with 5-fluorouracil produced objective response rates ranging from 27-34% in two studies of patients with prior chemotherapy. Capecitabine was designed as an orally administered, tumor selective fluoropyrimidine, preferentially converted to 5-FU at the tumor site by the higher levels of pyrimidine nucleoside phosphorylase (PyNPase) in tumor tissues compared to normal tissues. The end result is higher concentrations of 5-fluorouracil in tumor relative to surrounding normal tissue. This trial will investigate the activity of this novel capecitabine/oxaliplatin (CAPOX) combination in patients with advanced disease. In addition, an exploratory analysis will correlate response with thymidine synthase and thymidine phosphorylase expression in primary tumor samples.
The purpose of this study is to attempt to find better tolerated doses and schedules of this highly effective combination chemotherapy regimen.
This is a two arm, double-blind randomized study looking at the effect of zoledronate, a bisphosphonate, on the bone mineral density (BMD) of postmenopausal women with breast cancer.
Patients with locally advanced or metastatic breast cancer and with measurable primary breast tumor will be treated with 70mg docetaxel combined with ketoconazole. Serial tumor biopsies and plasma samples will be taken for gene expression and proteomics studies to identify biomarkers that may predict for treatment response.
We hypothesize that changes in tumor gene expression profiles vary in response to different sequences and types of chemotherapy, and that gene expression changes will correlate with tumor response. We are also looking to correlate drug pharmacokinetics and treatment toxicity with genotype of drug metabolizing enzymes and tranporters.Patients with metastatic breast cancer and who have measurable primary breast tumor will be randomized to one of two alternating sequences of adriamycin and docetaxel. Serial tumor biopsies and plasma samples will be obtained for gene expression and proteomic studies to identify biomarkers that will predict for chemotherapy response.
Tumors are heterogeneous with varying response to chemotherapeutic agents. We hypothesize that tumors that are sensitive to a particular chemotherapeutic agent have a distinctive tumor protein profile compared to those that are resistant. We further hypothesize that since tumor is continuously perfused by serum, serum protein profile can be used as a surrogate marker of tumor protein profile. The primary objective of this study is to identify a serum protein profile that predicts gemcitabine/carboplatin sensitivity or resistance in breast cancer patients with prior exposure to anthracyclines and taxanes. Secondary objectives are to establish the serum protein profile of breast cancer patients who have had prior exposure to anthracyclines and taxanes, and to study the pharmacogenetics of gemcitabine toxicity by correlating germline genotype of transporters and drug metabolizing enzymes with plasma and intracellular gemcitabine pharmacokinetics.
The purpose of this study is to evaluate the impact on survival and quality of life of maintaining hemoglobin in the range of 12 to 14 g/dL using epoetin alfa or placebo in patients starting chemotherapy for metastatic breast cancer for the first time.
