Fulvestrant is an ER antagonist with no agonist effects, which binds, blocks and degrades the ER. Fulvestrant is comparable to third-generation aromatase inhibitors in terms of efficacy and tolerability for patients who have progressed on prior tamoxifen therapy and past studies have found all three-third-generation AIs to be at least as good as tamoxifen in first-line metastatic therapy in postmenopausal women. Fulvestrant has been studied little in premenopausal women despite of its attractive mechanism of actions. The clinical effectiveness of fulvestrant as a treatment for advanced breast cancer has previously been demonstrated at the standard dose (AD; 250 mg/mo) in several phase III clinical trials in postmenopausal women. However, there is evidence to suggest that doses of fulvestrant higher than 250 mg may have greater pharmacodynamic activity against the ER pathway. Moreover, dose-dependent clinical activity has been observed for fulvestrant. The activity of a fulvestrant high-dose (HD; 500 mg/mo) regimen has been investigated in two recent studies. A pilot Japanese study showed fulvestrant HD to have clinical activity in the treatment of advanced or recurrent breast cancer, to be well tolerated, and to result in plasma levels approximately double those seen with fulvestrant low-dose. Subsequently, a neoadjuvant study comparing fulvestrant low-dose and high-dose reported that significantly greater Ki67 and ER downregulation was achieved with the high-dose compared with the low-dose regimen and that both doses were well tolerated. A recent randomized trial also showed superior outcome of high-dose fulvestrant than AI. Based on this rationale, we introduced high-dose fulvestrant with LHRH agonist as a randomized trial comparing with AI plus LHRH agonist and LHRH alone in premenopausal metastatic breast cancer patients who failed to tamoxifen treatment.
The standard treatment for localized breast cancer is based on conservative surgery (when possible) followed by radiation therapy (RT) delivered to the whole breast. The recommended total RT dose is 45 to 50 Gy delivered in 4.5 to 5 weeks followed by a 10 to 16 Gy boost to the tumor bed for 1 to 1.5 weeks. The rationale for the development of APBI was based on the difficulty for many patients to reach RT centers to receive standard whole breast irradiation (WBI) after conservative surgery. APBI offers decreased overall treatment time and several theoretical advantages over WBI, including a decrease in dose delivered to uninvolved portions of the breast and adjacent organs. If equivalence between the two treatments can be shown, then APBI will be considered as a historic evolution in breast cancer management. In this phase III trial, designed in postmenopausal women >50 years of age, the objective is to compare the effectiveness and safety of APBI compared with whole breast irradiation. This study is also designed to ensure high quality criteria for surgery, pathology and RT techniques in the 3 arms and will allow to provide data on economics and costs.
Adequate quality and quantity of RNA may be extracted from paraffin-embedded tumor blocks for gene expression analysis. This has clinical relevance as gene expression signatures may then be profiled using archival tumor blocks, which are more readily available than frozen tissues.
In low-risk node-negative breast cancer patients adjuvant chemotherapy should be spared. The identification of this subgroup can be based either on clinical and pathological or on tumour-biological criteria. Due to their high prognostic impact, the tumour-biological invasion markers uPA/PAI-1 (urokinase-type plasminogen activator and its inhibitor PAI-1) are potential candidates to effectively assess the risk of relapse in node-negative breast cancer. This study is aimed to compare the risk assessment by the traditional clinico-pathological factors and by tumour-biological factors. The second study question refers to the comparison between an adjuvant combination treatment with FE100C*6 and a sequential treatment with FE100C*3 and Docetaxel*3.
Primary objective: - To evaluate the disease-free survival (DFS) in the two randomized arms after therapy with LC vs. EC in chemo-naive Her2-patients with stage I or II breast cancer Secondary objectives: - To assess the overall survival (OS) - To establish the safety profile by assessing the toxicities and tolerability - To assess the quality of life (QoL) - To evaluate survival correlation with biomarkers expression.
The purpose of this research study is to see if a participant's nipple and areola can be safely preserved by adding radiation to these areas after a nipple-sparing mastectomy and immediate breast reconstruction.
Currently the standard of care is to treat early stage invasive breast cancer or ductal carcinoma in situ (DCIS) with a combination of lumpectomy and radiotherapy, known as "breast-conserving therapy" (BCT). The traditional method of giving radiation therapy after a lumpectomy is to the whole breast. However the investigators do not know if the whole breast needs to be receive radiation to better control your cancer or only a more limited area of the breast surrounding the tumor. The purpose of this study is to see the side effects of delivering partial breast irradiation (PBI) instead of whole breast irradiation (WBI). PBI is radiation therapy given only to the area of the breast where the cancer was removed. Another purpose of this study is to look long term at the rate at which cancer comes back in the same breast after PBI. WBI is radiation therapy given 5 days a week for 5 to 7 weeks to the whole breast. Partial breast irradiation radiation therapy (PBI) is much shorter than whole breast irradiation. The investigators propose to deliver the PBI radiation therapy, for a few minutes a day, once a day, five days a week, for 2 weeks. In this study the investigators will learn about the good and bad effects of PBI radiation therapy. In this study, the investigators will also learn about how the breast looks after surgery and radiation therapy.
The goal of this behavioral research study is to compare two different forms of relaxation programs that will include stretching and relaxation techniques, in order to learn if and how well they may help to improve physical and emotional well-being. This will be tested in patients with breast cancer who are receiving radiation therapy. For comparison purposes, there will also be a group of participants that does not take part in the relaxation programs. This is an investigational study. The relaxation programs are being compared for research purposes only. An "assessment" is any time you complete a set of scheduled activities for this study, such as tests and questionnaires. Up to 700 patients will take part in this study. All will be enrolled at MD Anderson.
Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate may fight breast cancer by blocking the use of estrogen by the tumor cells This phase IIb trial studies how well low-dose tamoxifen citrate works in reducing breast cancer risk in radiation-induced cancer survivors.
