The 105-15-201 study is designed to assess the effectiveness and tolerability of the combination of heat-activated target therapy (radiotherapy + hyperthermia + lyso-thermosensitive liposomal doxorubicin) of loco-regional relapse in breast cancer patients.
The goal of this study is to determine if co-administration of metformin and doxorubicin in breast cancer patients receiving neoadjuvant or adjuvant therapy will reduce the number of patients who develop a significant change in left ventricle ejection fraction (LVEF).
This intraoperative study is a prospective study analyzing specimens from fifty subjects. Patients scheduled to undergo breast-conserving surgery will be recruited in accordance with the inclusion and exclusion criteria. The study period per subject is the time it takes to assess the ex vivo breast tissue sample using the study device. Image review will be conducted during surgery and compared to the margin status findings in the post-operative pathology report.
This randomized Phase III trial studies how well the combination of fulvestrant and everolimus together or the combination of anastrozole, fulvestrant and everolimus together, improve progression-free survival (PFS) versus fulvestrant alone.
Early identification of patients at risk for cardiotoxicity represent a primary goal for cardiologist and oncologist From all adjuvant trials echocardiography is ideal for evaluating Left Ventricular function though its operator dependent. The use of other technique such as endomyocardial biopsy, is troublesome in clinical practice Cardiac magnetic resonance imaging (MRI) have greater reproducibility in evaluating left ventricular ejection fraction (LVEF). This technique provides morphological, functional, perfusion, and viability information in one assessment. It is expensive and time consuming but id the diagnostic method of choice for patients with technically limited images from ECG and in patients with discordant information that is clinically significant from prior tests
The purpose of the study is to determine if it is possible to identify and perform a needle biopsy of the sentinel lymph node. The investigators hope to identify breast cancer cells in the lymph nodes under the arm without making an operation necessary. The rationale for this study is that for patients without enlarged lymph nodes under the arm, sentinel lymph node biopsy is the standard way of determining if breast cancer has spread to the lymph nodes under the arm. While the complications from a sentinel lymph node dissection are less than that of a complete axillary lymph node dissection, sentinel lymph node dissection still carries small risks of arm swelling, decreased movement, fluid collections, nerve injury, and pain. Furthermore, the majority of sentinel lymph nodes do not contain cancer. The investigators hope to develop a method to find cancer in the axillary lymph nodes and avoid the complications of an operation.
The purpose of this study is to collect prospective data for use as a comparator for future subsequent studies attempting to increase the efficacy or reduce the toxicity of gamma knife radiosurgery.
The incidence of brain metastases (BM) in metastatic breast cancer is increasing, due to the improvement in the control of systemic disease, and due to an improved detection through imagery. The treatment management of single BM remains controversial. Indeed, even though it is widely accepted that local treatment increases the median survival time in patients having a good prognostic status, the adding of "adjuvant" whole-brain radiation therapy (WBRT) is currently subject to controversy, due to its potential toxicity. Yet, two randomized trials have demonstrated a clear increase in intra-cerebral recurrence and in death from neurologic origin in case of absence of "adjuvant" WBRT, without change in overall survival (but overall survival was not a primary endpoint in any of these studies). The data from literature on cognitive toxicity (CT) of WBRT on BM are scarce and sometimes controversial. CT of WBRT affects the subcortical frontal functions. It is postulated that the alteration of hippocampal neurogenesis (mainly due to inflammation process), situated in the subgranular zone of the dentate gyrus, has an essential role in the development of these brain dysfunctions. It has been shown that the incidence of BM in the hippocampal region (hippocampus + 5mm expansion) is low, in the range of 8,6%. New irradiation techniques, in particular intensity-modulated radiotherapy associated with rotational radiotherapy, allow to modulate the dose on an intra-cerebral structure, all the while distributing an adapted dose to the remaining brain. This prospective, randomized study, will compare, through a battery of neuropsychological tests, the cognitive impact of WBRT of 40 Gy in 20 fractions with or without hippocampal avoidance by intensity modulated radiotherapy, in patients presenting with a single operated brain metastasis of breast cancer. If the hippocampal avoidance leads to a significant improvement in cognitive function, this radiotherapy scheme could become the standard postoperative treatment to be proposed to patients presenting the best prognostic factors. This would allow to prevent long-term cognitive deficit, while preserving WBRT benefit on intra-cerebral control. Justification of evaluation criteria : Principal criteria : Evaluation criteria to assess cognitive toxicity have been selected on the basis of the recommendations from C. Meyers and P. Brown, who propose an adapted test battery to evaluate memory, verbal function, visual and motor coordination, and executive function. The selected tests have been validated, also in French. They comprise HVLT-R (Hopkins Verbal Learning Test Revised), COWAT (Controlled Oral Word Association Test), Grooved Pegboard test, TMT A and B (Trailmaking tests A and B), and MMSE. The calculation of patient numbers was based on the HVLT-R test, as memory is thought to be the most frequently affected domain. The tests will be performed before treatment ("baseline" cognitive function), at 4 months and at 12 months. In case of a missing answer to the evaluation tests, the reason(s) for not answering will be noted. Secondary criteria : Quality of life : QLQ-C30, QLQ-BN20, ADL, IADL Intra-cerebral Progression-free survival (PFS) Overall survival.
This study is based upon the following points: 1. Resistance to trastuzumab, either primary or secondary, is a clinically relevant issue. 2. PI3K/AKT activation, due to loss of expression/function of PTEN and/or activating mutations of PIK3CA, is a mechanism of resistance with clinical relevance in breast cancer. Such activation can be detected by: - IHC evaluation of PTEN protein expression - genotyping of PIK3CA exon 9 and 20 - IHC evaluation of phospho-AKT expression 3. BKM120 is an effective PI3K inhibitor. BKM120 and anti-HER2 therapy may have a synergistic antitumor activity in preclinical model of HER2+ breast cancer. 4. Lapatinib is an effective anti-HER2 therapy in trastuzumab-resistant disease. 5. For the evaluation of novel targeted therapies, selecting a patient population enriched for activation of the target to be modulated should allow to maximize the differences in clinical outcome that are expected in the experimental arm, and thus to minimize the patient number to include. 6. We propose to test in a phase I/II study the combination of lapatinib and BKM120 in trastuzumab-resistant HER2+ MBC patients, enriched for activation of PI3K/AKT as detected by loss of expression of PTEN (IHC), and/or mutation of PIK3CA and/or overexpression of phospho-AKT (IHC). Only for phase II patients, mutational status will be an inclusion criteria. For phase I patients molecular status will be a retrospective exploratory analysis.
The purpose of the National Breast Cancer Lymphedema Registry is to collect health information in order to study the lymphedema as a complication of breast cancer treatment. The investigators hope to learn whether early diagnosis will help to prevent lymphedema or, if it does occur, to reduce the severity.
