RATIONALE: Drugs used in chemotherapy, such as ixabepilone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing or by stopping them from spreading. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ixabepilone together with vorinostat may kill more tumor cells. PURPOSE: This randomized phase I trial is studying the side effects, best way to give, and best dose of vorinostat when given together with ixabepilone in treating patients with breast cancer that has spread to another place in the body.
The purpose of this study is to determine the effectiveness of Estradiol treatment for advanced breast cancer that is hormone receptor negative and Her2/neu negative. The study will also use tumor tissue from your original diagnosis or from a biopsy you may have had for your cancer to look at hormone receptors in the lab. The tissue left over from your previous surgery or a previous biopsy will be used for research tests to check whether a different estrogen receptor (estrogen receptor beta) is seen in the tumor and if that makes estrogen work better.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery kill any remaining tumor cells and may be an effective treatment for breast cancer. PURPOSE: This phase II trial is studying how well radiation therapy works in treating women with locally recurrent breast cancer previously treated with repeat breast-conserving surgery.
Phase 1 of this study will evaluate the maximum tolerated dose (MTD) of XL147 when given in combination with letrozole (Femara) and of XL765 when given in combination with letrozole. After the MTD is established for each combination (Phase 2), subjects will be enrolled to evaluate the preliminary efficacy and safety of these combinations in subjects with breast cancer refractory to a non-steroidal aromatase inhibitor that is ER+/PGR+ and HER2-. Letrozole is used in the treatment of different types of breast cancer, but patients can develop resistance. Upregulation of PI3K activity is one of the most common characteristics of human cancer cells, including breast tumor cells. Activation of PI3K results in stimulation of AKT and mTOR kinases, resulting in the promotion of tumor cell proliferation and survival. Preclinical and retrospective clinical data suggest that aberrant activation of the PI3K pathway may play a role in aromatase inhibitor resistance in patients with ER+, HER2- breast cancer. XL147 is a potent inhibitor of PI3K, and XL765 is a potent dual inhibitor of PI3K and mTOR; therefore either of these compounds in combination with letrozole warrants clinical investigation.
HSP90 inhibition is a potentially new targeted drug modality in the treatment of HER2 positive, trastuzumab refractory breast cancer. Little is known about the pharmacodynamics of HSP90 inhibitors in vivo, but non-invasive PET/CT imaging in a xenograft mouse model could visualize and quantify HER2 reduction after AUY922 treatment by 89Zr-trastuzumab PET imaging. Two doses of 50 mg/kg AUY922 resulted in a decrease in HER2 expression of approximately 50%, quantified 6 days after the last administration of AUY922. Visualizing HER2 expression in breast cancer patients before and early following HSP90 inhibition by means of 89Zr-trastuzumab PET, is likely to provide insight in the early in vivo effect of HSP90 inhibition and could potentially support patient tailored therapy.
The aim of this study is to assess the patient's perception about and willingness to take his or her medication and the influencing factors interfering with taking medication.
Nationwide cluster-randomised trial of extending the NHS breast screening age range in England
The purpose of this study is to see whether low level laser therapy can help maintain normal hair growth on the scalp in people receiving chemotherapy, which is generally associated with hair loss.
This study explores how aromatase inhibitor therapy affects risk factors for heart disease in postmenopausal women with breast cancer.
