Filter by:The investigators hypothesize that the combination of Gemzar®, Abraxane® and Avastin will increase the progression-free survival (PFS) in patients with first line metastatic breast cancer and in patients who received neoadjuvant and/or adjuvant chemotherapy present with definable metastatic disease, 6 or more months after primary treatment.
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This clinical trial is studying how well erlotinib works in treating women undergoing surgery for stage I, stage II, or stage III breast cancer.
This is a phase II one arm study. Patients with HER2 (Human Epidermal Growth Factor Receptor 2)positive early stage breast cancer will receive ABI-007 and vinorelbine in combination with trastuzumab before having breast surgery.
Surgery for breast cancer has a major role in enhancing long term survival and cure, but several physiological aspects associated with surgery are implicated as enhancing tumor spread and formation of distant metastases. These include: an increase in pro-angiogenic factors, direct spread of tumor cells, accumulation of grown factors, immune suppression and direct effects of anesthetics and opiate pain relievers on cancer cells. Some of these pro-metastatic mechanism may be blocked by the interventions proposed in this study, namely by administration of beta-adrenergic blockers and COX2 inhibitors around the time of surgery. Studies have shown that surgery increases levels of catecholamines and prostaglandins, which in turn may promote the release of pro-angiogenic factors such as VEGF, and enhance vascularization of micro metastases. Opiates given for pain relief during and after surgery have been reported to enhance tumor cell division and cause immune suppression. The immune system is significantly suppressed during surgery. This suppression has been shown to affect the systemic resistance to infection as well as neoplastic metastatic processes. Several studies have shown that increased levels of catecholamines and prostaglandins add to the immune suppression. Studies in rats found that peri-operative administration of the beta beta-blocker propranolol together with the COX2 inhibitor etodolac significantly reduced the suppression of NK cell activity as well as the risk for distant metastases. A recent retrospective clinical study found that among breast cancer patients treated with a combination of regional anesthesia and a COX inhibitor the recurrence rated were significantly less than among patients undergoing surgery without these two interventions. The purpose of the proposed prospective trial is to examine if peri-operative administration of the combination of a beta-blocker together with a COX2 inhibitor will prevent suppression of cellular immunity, decrease VEGF levels, and decrease cancer recurrence rates. In the proposed study breast cancer patients will be treated with a combination of a beta-blocker and COX2 inhibitor (or placebo) before, during and after surgery. (A control group of healthy women will serve as untreated controls). The variables which will be examined are: number and activity of NK cells, levels of Th1 and Th2 cytokines, serum stress hormones and angiogenic factors, and the ability of leukocytes to produce Th1 and Th2 cytokines as a result of in vitro stimulation. In addition to these immediate parameters, long term follow up will be conducted in order to determine the effect of the intervention on long term cancer recurrence over five years. Statistical analysis will be done using t-tests, ANOVA, and multivariate regressions, with regard to the known risk factors for recurrence such as tumor grade, lymph node involvement etc. Sample size for immunological parameters will be 40 patients in each group and 20 healthy women. Sample size for estimates of cancer recurrence at five years of follow up wiil be 460 women (230 in each group). This sample size provides a power of 80% to detect a 50% reduction in cancer recurrence at an α of 0.05.
This is an investigation of the safety and efficacy of Maxy-G34 in breast cancer patients treated with TAC chemotherapy. Maxy-G34 will be given as a single injection during each cycle of chemotherapy, for a planned total of six chemotherapy cycles.
This study aims to evaluate if a light based technique, called Optical Breast Spectroscopy (OBS) formerly known as Transillumination Breast Spectroscopy (TiBS), can be used to detect differences in breast tissue between high- and low-risk populations and within the high-risk population between BrCa1 or 2 carriers and non-carriers. These differences may include differences in breast tissue composition and metabolism at time of enrollment into the study (possibly reflecting changes occurring in adolescence) and in the rate of breast tissue change over time (possibly reflecting rate of tissue transformation from normal to ultimately malignant state).
The purpose of this study is to evaluate a dynamic near infrared imaging device for characterizing suspicious breast lesions
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving letrozole together with lapatinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This randomized phase II trial is studying how well giving letrozole together with lapatinib works in treating postmenopausal women with stage I, stage II, or stage III breast cancer that can be removed by surgery.
The goal of this clinical research is to learn if RAD001 given in combination with chemotherapy will turn off the signaling pathway (a chain of information that tells cancer cells to grow quickly) and make the chemotherapies given on this study more effective. Primary Objective · To determine if the addition of an mTOR inhibitor to standard neoadjuvant chemotherapy in patients with triple receptor-negative breast cancer causes molecular changes (inhibition/activation) of the PI3K/PTEN/AKT pathway. Secondary Objectives - To evaluate pathologic complete response (pCR) rates for each treatment group. - To evaluate the relationship between pCR and the molecular changes (inhibition/activation) of the PI13K/PTEN/AKT pathway in each treatment group. - To evaluate overall response rates (ORR) for each treatment group. - To assess the toxicity of both regimens and to evaluate the relationship of toxicities with PI3K/PTEN/AKT pathway status.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving paclitaxel together with sorafenib may kill more tumor cells. PURPOSE: This randomized phase II trial is studying how well paclitaxel works when given together with or without sorafenib in treating patients with locally recurrent or metastatic breast cancer.
