Filter by:This Phase 3, multicenter, randomized, double-blind, placebo controlled study is designed to evaluate the efficacy and safety of atezolizumab (MPDL3280A, an anti-programmed death-ligand 1 [PD-L1] antibody) administered in combination with paclitaxel compared with placebo in combination with paclitaxel in participants with previously untreated, inoperable locally advanced or metastatic, centrally confirmed TNBC. Participants will be randomized in a 2:1 ratio to receive atezolizumab or placebo plus paclitaxel until disease progression or unacceptable toxicity or end of study, whichever occurs first (maximum up to approximately 40 months). In addition, the Sponsor may decide to terminate the study at any time.
The aim of the present study is analyze the effects of combined training program (resistance and aerobics) in comparison with a non-training group on quality of life, as well as on neuromuscular and cardiorespiratory parameters in breast cancer patients in stages one to three who have finished their treatment, such as surgery, chemotherapy and radiotherapy. Therefore, 42 women will be randomly divided into two groups: combined training group and control group. The subjects of the combined training group will undergo the intervention three times a week for eight weeks. The combined group will carry out both resistance and aerobic exercises in the same session. The resistance training will be comprised by ten exercises which will alternate body segments with maximum repetitions in the first set and the lower limit of the repetitions interval in the next sets. Along the training, the number of series will be increased whereas the number of repetitions will be decreased. The intensity of the aerobic exercises will be based on the percentage of the heart rate of the anaerobic threshold on the first weeks and on the speed of the anaerobic and aerobic threshold on the last weeks. Before and after the intervention, there will be evaluation of maximal dynamic strength of knee extensors and elbow flexors, maximum voluntary isometric contraction of knee extensors, maximum muscular activity of vastus lateralis and rectus femoris, muscle thickness of knee extensors, peak oxygen uptake and ventilatory threshold, quality of life and cancer-related fatigue. Data will be analyzed by Generalized Estimating Equations (GEE) and Bonferroni's post-hoc (α=0,05), including both protocol and intention to treat.
This is a multicentric, open-label,non-randomized concurrent control, 1:1 match,non-inferiority trial that assesses the efficacy and safety of neoadjuvant chemotherapy regimen DC-T and EC-T in breast cancer patients.
This study retrospectively looks at changes in Echocardiographic parameters while using transtuzumab
Comparing changes in biomarkers from a diagnostic core needle biopsy to surgical pathology specimen or repeat core needle biopsy.
Breast cancer is the second most common form of cancer in women and the most frequent cause of death. Despite breast screening programs, a substantial number of women are diagnosed with cancers greater than 2 cm in size or locally advanced disease, which is best treated with neoadjuvant chemotherapy (NAC) prior to surgery. Approximately 10% of women diagnosed with breast cancer annually will have locally advanced breast cancer, defined as stage III disease, where the cancer has either spread to regional lymph nodes and/or other tissue in the area of the breast, but not to distant sites. NAC offers the advantages of downstaging the disease, potentially reducing the extent of surgery. Presently, gadolinium enhanced MRI is the standard test used to monitor disease response to chemotherapy, and demonstrates changes in tumour size and extent between pre-NAC and post-NAC. Unfortunately, changes in tumour size may occur late in treatment regimen, thus producing false-negative results on early magnetic resonance imaging (MRI). Therefore, newer imaging techniques beyond anatomical imaging are needed to identify tumours that are unresponsive to chemotherapy and potentially change treatment plan early on to avoid significant morbidity associated with prolonged chemotherapy. A novel MRI technique utilizing hyperpolarized pyruvate has the potential to detect pathophysiological response early in the treatment regimen and would therefore allow for earlier identification of nonresponders and subsequent early modification of treatment regimens, if necessary.
Phase 1/2 study, open, monocenter, non-randomized
The purpose of this study is to see how effective the combination of the two chemotherapy drugs (carboplatin and nab-paclitaxel) are when added to a third drug, pembrolizumab. Pembrolizumab is an investigational (experimental) drug that works by reinvigorating the immune system, allowing it to target and destroy cancer cells. Pembrolizumab is experimental because it is not approved by the Food and Drug Administration (FDA) for this type of breast cancer treatment.
This study will evaluate the effect of highly accelerated external beam radiotherapy (EBRT) in 5 fractions over 10 days compared to 15 fractions over 3 weeks for early as well as locally-advanced stage breast cancer. Primary endpoint will be chronic toxicity (breast deformation and retraction). Secondary endpoints are acute toxicity, loco-regional and distant tumor control, patient reported QoL and cosmetic satisfaction. Patients with lymph node irradiation will be closely monitored for radiation induced plexopathy.
There is no consensus regarding which alternative is the best anesthesia for breast surgery, general anesthesia and morphine for postoperative analgesia or a combination of regional anesthesia and general anesthesia that possibly attenuates or abolishes the need for morphine. The current study aims to determine which of the two strategies that is best in relation to postoperative pain, nausea and risk of recurrence of the disease.
