Filter by:Validation of the PEFS to detect breast tumors will be performed by means of a prospective trial. Subjects will participate for 1 clinic visit. Readings from the PEFS will be studied for reproducibility and predictive ability. Data analysis will be iterative, moving on with each modification of the device until the final prototype is created.
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.
The breast MRI is used in the preoperative scenario to evaluate the extension of a newly diagnosed breast cancer and to screen the contralateral breast. The scan consists of a series of images taken after the use of intravascular contrast media that may detect areas of enhancement that look malignant, but are actually benign tissue, producing a false positive result. The investigators aim to evaluate a novel MRI sequence of images that does not use contrast, diffusion tensor imaging (DTI). Addition of DTI sequence does not add significantly to the time of standard breast MRI exam. This novel technique provides improved detection of tissue microstructure and is able to differentiate malignant from benign tumor. Hence, the investigators hypothesize that DTI may decrease the false positive rate when compared with standard dynamic contrast-enhanced (DCE) MRI.
Everolimus shows a large interpatient variability with fixed dose administration. These very different exposure levels between individuals can result in supratherapeutic or subtherapeutic exposure levels and consequently in over- or undertreatment, respectively. Dose individualization based on the measured drug concentration could theoretically result in less toxicity and more efficacy. Nowadays everolimus exposure is determined by everolimus concentration in whole blood. Therefore, a vena puncture is always necessary. This is invasive and requires patients to come to the hospital. It would be convenient for patients to have their everolimus blood concentration determined by dried blood spot (DBS) analysis. With DBS only a single drop of blood from the finger is necessary, which can be done at home and sent by regular mail for analysis. Previous studies have shown the feasibility of this approach. In patients with cancer treated with everolimus 10mg once daily, the correlation between everolimus DBS concentrations and whole blood concentration is yet unknown. Therefore, the investigators want to determine the everolimus concentration collected with DBS from a finger prick with everolimus concentration from whole blood and everolimus concentration collected with DBS from whole blood. In addition, possibly a relatively high everolimus concentration in saliva could be correlated with the incidence and severity of oral mucositis. Determination of drug concentration in saliva has also been proven to be feasible before. Therefore, in this study the investigators want to determine whether the everolimus concentration in saliva correlates with the incidence of oral mucositis and how everolimus concentration in saliva correlates with everolimus concentration in whole blood.
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.
Dynamic infrared thermography (DIRT) is an imaging method that does not require ionizing radiation or contrast injection. The study evaluates if DIRT can be an alternative to computed tomographic angiography (CTA) in perforator mapping. DIRT findings are compared with hand-held Doppler, CTA and intraoperative findings.
The purpose is to evaluate whether non invasive in vivo imaging of the estrogen receptor (ER) presence in metastatic breast cancer patient by means of 18F-fluoro-estradiol (FES) positron emission tomography (PET) can be used to predict treatment response to palbociclib plus letrozole. As ER expression predicts response to palbociclib in metastatic breast cancer patients the investigators hypothesize that lesions with low uptake on FES-PET will not respond to the combination of letrozole plus palbociclib.
The purpose of this study is to estimate the efficacy and safety of PEG-rhG-CSF in patients with breast cancer receiving chemotherapy.
