Filter by:The purpose of this study is to determine the effect of exemestane on the pharmacokinetics (PK) of entinostat and to determine the effect of entinostat on the PK of exemestane in patients with locally recurrent or metastatic estrogen receptor positive (ER+) breast cancer. Additionally, this study will evaluate the safety and tolerability of entinostat in combination with exemestane, and assess the effectiveness of entinostat in combination with exemestane in terms of best overall response and overall survival.
The study will consist of two parts. In Part 1, the safety of pembrolizumab (MK-3475) in combination with one of three different chemotherapies will be assessed in the treatment of locally recurrent inoperable or metastatic triple negative breast cancer (TNBC), which has not been previously treated with chemotherapy. In Part 2, the safety and efficacy of pembrolizumab plus background chemotherapy will be assessed compared to the safety and efficacy of placebo plus background chemotherapy in the treatment of locally recurrent inoperable or metastatic TNBC, which has not been previously treated with chemotherapy. The primary hypotheses are that: 1. the combination of pembrolizumab and chemotherapy prolongs Progression-Free Survival (PFS) compared to placebo and chemotherapy in: - all participants, - participants with programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 tumors, and - participants with PD-L1 CPS ≥10 tumors, and 2. the combination of pembrolizumab and chemotherapy prolongs Overall Survival (OS) compared to placebo and chemotherapy in: - all participants, - participants with PD-L1 CPS ≥1 tumors, and - participants with PD-L1 CPS ≥10 tumors.
In patients with early-stage breast cancer, chemotherapy has substantially improved survival rates. Improvements in outcomes, however, are compromised by the considerable toxicities associated with chemotherapy, the most notable being neutropenia. Neutropenia is the presence of abnormally few white blood cells, leading to increase susceptibility to infection and can require hospitalization and need for intravenous antibiotics and is sometimes fatal. Febrile neutropenia (FN) can also be associated with treatment delays and dose reductions, potentially compromising treatment efficacy. Patients can receive medication to reduce the risk of FN such as Neupogen (filgrastim) as a daily injection for 5, 7 or 10 days. Since there is genuine uncertainty among healthcare professionals as to which administration schedule of Neupogen is the best for patients, the investigators are performing a randomized study for which patients will receive either 5, 7 or 10 days of Neupogen. Neupogen can cost approximately $200/injection, so if a physician prescribes 10 days for 8 cycles of treatment, this can cost $16,000 compared to a 5 day treatment which would cost half this. In addition to cost savings, many patients are not able to give themselves injections on a daily basis and require nursing resources which are utilized at high cost. This study will use an oral consent model to compare 5, 7 and 10 days of Neupogen to evaluate rates of febrile neutropenia and hospitalization.
Healthy premenopausal women were enrolled in a diet intervention study that examined the effect of a combination EPA/DHA supplement on risk factors associated with breast cancer. In a randomized cross-over design, women consumed their habitual diet with a supplement for three menstrual cycles, had three cycles of wash-out and then consumed a low-fat diet with the same supplement. Blood, urine and nipple aspirate fluid were collected periodically over the 10 month protocol and analyzed for biomarkers associated with supplementation and future risk of breast cancer.
The purpose of this study is to review retrospectively cases of breast cancer of the centers belonging to the BREST UNIT Tuscany North-West Wide Area and compare the imaging characteristics (ultrasound, mammography and mammary MRI if available) of breast cancer with the corresponding histological reports and assess whether in women <40 years the typical imaging presentation pattern of malignancies observed in women> 40 years are confirmed.
This prospective, multicenter, observational study aims to explore a comprehensive approach to the care of early breast cancer patients in a regional health territory (including 1.5 million women and characterized by a breast cancer incidence and mortality higher than national ranges), incorporating all healthcare actors inside and outside the hospital.
Breast cancer is the most frequent malignancy in the female population Brazilian, except non-melanoma skin tumors. Surgery plays an important role in regional spot disease control and the definition of parameters for the adjuvant treatment indication. Surgical site infections (SSI) are defined as wound infections occur following invasive procedures, corresponding to 14-16% of all infections nosocomial in hospitalized patients, the most common among patients surgical. SSIs should be examined as potential wound contamination surgical, understood as the number of micro-organisms in the body and / or tissue being operated. Considering this aspect, the cancer surgery breast are classified by their potential for contamination by clean. The use of antibiotics to prevent the SSI in mastectomies is not standardized in Handbook of National Health Surveillance Agency due to the effectiveness of undocumented prophylaxis Thus the use of antibiotics may vary among services. So this randomized clinical trial to evaluate the influence of the use of Prophylactic antibiotics in SSI rates in oncological breast surgery.
The purpose of this study is to test a program designed to increase African American and Hispanic American women's scientific literacy, knowledge of clinical trials, and to facilitate breast cancer clinical trial participation.
Prospective, randomized, open label, two arms,, phase 0 clinical trial. HER2-negative breast cancer patients recently diagnosed will be screened for trial participation. A biopsy will be scheduled the week prior to or the same day as the FDG PET. Paraffin-embedded tumor samples will be used to evaluate the stainings of Ki67, cleaved caspase-3 and microvessels, and frozen tumor samples will be used to evaluate SDH staining. The FDG-PET will be followed by the bevacizumab dose (15 mg/kg IV, single dose). After one week, the PET will be repeated in order to detect the patients that have experienced FDG uptake decay. Right after, treatment with ME-344 (arm 1) or no treatment (arm 2) will start. ME-344 will be administered at 10 mg/kg on day 8, 15 and 22. Surgery will be performed on day 28 (thus, 4 weeks after the bevacizumab dose, which is considered a safe window for antiangiogenics). Fragments of the surgical specimen will be collected. Paraffin-embedded tumor sample will be used to repeat (and compare) the stainings of Ki67, cleaved caspase-3 and microvessels, and frozen tumor sample will be used to repeat (and compare) SDH staining. Patients will come off trial in case of consent withdrawal, unequivocal disease progression is observed, unacceptable toxicity occurs, or in case of intercurrent disease or any other condition deemed incompatible with continuation in the clinical trial by the investigator.
This study evaluates the feasibility and efficacy of neoadjuvant tamoxifen for patients with locally advanced hormone receptor positive breast cancer in a low/middle income country.
