Filter by:The purpose of this study is: Phase I: To determine the Trastuzumab maximum tolerated dose (MTD) when weekly administrated by intrathecal or intraventricular route to reach a intra CSF target concentration (30 µg/mL) near the conventional therapeutic concentration and depending on the dose-limiting toxicity (DLT) Phase II: Determination of antitumor activity trastuzumab when administrated by IT or intra-ventricular in terms of neurological progression-free survival at 2 months
The study is a prospective multi-centered cohort study designed to determine the safety and efficacy of AlloMax in immediate expander-based breast reconstruction. Specifically, the study is designed to determine if sterility of human acellular dermal matrix results in a lower incidence of infection and seroma. The study will determine if gamma radiation, as a method of terminally sterilizing human acellular dermal matrix, has a negative impact on graft incorporation into the host tissue.
The goal of this research is to further develop novel optical assay systems for intra operative assessment of tumor margins in partial mastectomy or mastectomy specimens.
The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System by comparing its performance to an extensive intraoperative frozen section protocol for Sentinel Lymph Nodes removed during standard Sentinel Lymph Node biopsy procedures from breast cancer subjects.
This study evaluates the effect of a psychological intervention to breast cancer patients and their partners compared to a control group receiving usual care
The purpose of the study is to evaluate the impact of an immunotherapy by IL-7 on CD4 lymphopenia, risks of severe haematological toxicity and tumor progression in metastatic breast cancer patients. The primary objective is to determine the optimal schedule to deliver CYT107 during chemotherapy based on restoration of CD4 count. This study is a phase II, randomised, double-blind, placebo-controlled, single-centre. 24 patients will be included in the study.
Breast cancer is the leading female cancer by a very wide margin in France. Despite widespread breast cancer screening, many cases of breast cancer are discovered at a locally advanced stage. The tumoral consequences of a cancer size greater than 3 cm are: increased risk of metastasis and death and, most often, impossibility of performing breast-conserving surgery (a mastectomy is usually advisable in case of a first surgical procedure). It is increasingly recommended to treat locally advanced breast cancers with neoadjuvant chemotherapy. Very numerous studies have shown that by proceeding that way, the oncologic prognosis was not harmed and, on the contrary, it was possible to obtain sufficient tumor response to allow breast-conserving treatment in more than 60% of cases. The use of zoledronic acid (Zometa) has an established place in the management of malignancies with a predilection for skeletal involvement (in particular metastasis). Although the main target of biphosphonates is the osteoclast, there is also preclinical data indicating that biphosphonates can have effects on cells other than osteoclasts, including tumor cells. Anti-tumor activity including inhibition of tumor cell growth and induction of tumor cell apoptosis, inhibition of tumor cell adhesion and invasion, and anti-angiogenic effects have been demonstrated. In addition several in vitro studies have shown that Zometa causes synergistic induction of breast cancer cell apoptosis when combined with clinically relevant concentrations of chemotherapy drugs such as paclitaxel and doxorubicin. Therefore testing of combinations of biphosphonates with these agents in breast cancer is of significant interest. In the context of locally advanced breast cancers, the combination of a bisphosphonate with neoadjuvant chemotherapy appears to have an important potential: preventing possible bone metastases, but also possibly amplifying the efficacy of the chemotherapy's tumoricidal activity, both on the primary tumor and on potential metastatic localizations. So it appears that, the use of bisphosphonates in a neoadjuvant situation presents a potentially favorable benefit-risk ratio. That is why we are proposing to perform a prospective randomized multicenter comparative study to evaluate 2 systemic neoadjuvant treatments, one with Zometa and the other without Zometa, in patients with locally advanced breast cancer. Zometa will be administered according to the usual administration procedure: one infusion every 3 weeks. The therapeutic response will be evaluated by studying the different biological markers (circulating blood and bone marrow tumor cells, serum cell apoptosis and neoangiogenesis markers, bone resorption markers, etc.), but also by analyzing clinical, radiologic, and histologic response and by breast conservation rates. The impact of other factors that may affect therapeutic response will be taken into account: aggressivity of the tumor, presence or absence of tumor receptors, tumor stage, etc. The purpose of the study is to show a marked benefit of treatment with Zometa in managing locally advanced breast cancers with synergistic action of the neoadjuvant chemotherapy and improvement in the laboratory parameters of tumor aggressivity. These markers will be used as surrogate markers of long term outcome.
Multicenter randomised phase II study of neoadjuvant therapy in HER2 positive early breast cancer. Primary aim is to evaluate the cardiac toxicity of the combined treatment (trastuzumab, docetaxel, bevacizumab, NPLD) in comparison to the standard therapy.
This NIH-NCCAM funded epidemiologic research is being conducted as an observational prospective case-control study of the use of Complementary and Alternative Medicine (CAM) and Integrated Oncology (IO) and their effects on breast cancer patients in community settings. Hypothesis: IO services improve patients' quality of life and decrease cancer recurrence rates in breast cancer patients as compared to women with similar disease states and prognoses who do not receive IO care, and may or may not use CAM treatment on their own.
The purpose of this study is to determine if proton radiation therapy will reduce the amount of heart that is exposed to radiation, thereby decreasing the frequency and/or severity of any cardiac side effects.
