Active clinical trials for "Breast Neoplasms"

The molecular breast imaging (MBI) is a potential modality to screen breast cancer. In this study, we compare and evaluate the recall rate/diagnostic efficiency of MBI, mammography and breast sonography, and aim to determine best ways of breast cancer screening.

Distress monitoring is an important issue in cancer survivors. However, conventional distress screening is very difficult to perform. This study investigates the efficacy of wearable device as a tool of distress monitoring in breast cancer survivors.

Monocentric open-label phase I/II trial aiming at evaluating, in adjuvant setting, safety (primary outcome), immunological and clinical efficacy (secondary outcomes) of a non replicating recombinant vaccinia virus expressing cancer/testis antigen (CTA) derived epitopes and CD80 and CD40 ligand (CD40L, CD154) costimulatory molecules in patients with CTA expressing tumors.

Shift work with circadian disruption has been linked with increased breast cancer incidence. The mechanisms for this effect are not yet completely understood. This study evaluates the impact of a previously developed sleep intervention in shift workers at risk of breast cancer; and assesses mediating variables that may explain the relationship between shift work and breast cancer. A sample of women night shift workers were provided with a sleep intervention. The intervention is a standard approach used in a sleep clinic and is delivered by telephone by a trained intervener. Hypothesis: The intervention will improve sleep in women night shift workers, which will in turn have a positive impact on biological and behavioural risk factors associated with breast cancer and quality of life.

The purpose of this study is to collect response and pharmacokinetic data on the oral administration of a cocktail combination of 4 drugs being developed for the indication of metastatic breast cancer.

Breast cancer is a public health problem in Mexico and its incidence rises when the woman is still premenopausal. Estrogen metabolism has been linked to breast cancer. Several studies reported that high concentrations of 2 hydroxyestrone (2OHE1) in urine have a protective effect for this neoplasia, whereas high concentrations of 16 alpha-hydroxyestrone (16αOHE1) in urine have the opposite effect, further has been reported that women with a ratio of estrogen metabolites 2OHE1:16αOHE1 in urine (REMU) less than 0.9, have ten times the risk of developing Breast Cancer than those women with an RMEU equal or more than 0.9. Other studies have showed that the active compounds of cruciferous vegetables, indole-3-carbinol (I3C) and its dimer, 3'3'diindolylmethane (DIM) induce benign pathway of metabolism of estrogens producing 2OHE1. Several studies, evaluate the pharmacokinetics and effect of I3C supplementation, finding that 300 to 600 mg of this compound are well tolerated and able to promote formation of 2OHE1 in women when supplemented for one month. In the case of DIM, only a pilot study has explored its effect in postmenopausal women with personal history of breast cancer in early stages, reporting an increase in the concentrations of 2OHE1. The purpose of this study was to evaluate the effectiveness of supplementation with DIM to increase urinary RMEU in premenopausal women at risk of Breast Cancer (RMEU less than 0.9). A clinical, randomized, double-blind study was performed with women attending on the urogynecology service of Institute National of Perinatology. Subjects were premenopausal women over 34 years who were healthy. The inclusion criteria's was had a RMEU less than 0.9 and were excluded for any medical condition, medication, or dietary or lifestyle habit that might interfere with estrogen metabolism. Patients were randomly assigned to one of two groups: one received orally at a daily dose of 75 mg of DIM for a period of 30 days and other group received orally at a daily placebo for a period of 30 days. All urine samples were collected from the women before DIM or placebo ingestion, after 30 days of DIM or placebo ingestion and finally after another 30 days once suspended supplementation. Analysis of the 2OHE1 and 16αOHE1 were determined using a commercially kit ESTRAMET™. The change in metabolites median concentrations and RMEU was assessed through the Wilcoxon test and these differences between groups through U Mann-Whitney test.

The purpose of this study is to evaluate the safety and efficacy of HER2-CAR-T cell Infusion for advanced HER2 positive breast cancer.

This is a prospective biomarker study to show that p4EBP1 staining predicts clinical benefit from treatment with everolimus in patients who are eligible for everolimus+exemestane treatment. This trial is not aimed at evaluating a drug activity. Everolimus and exemestane are prescribed within their approved indication as per usual practice and are not part of this trial.

The purpose of this study is to look at the efficacy (how does it work) and safety of gadobutrol when used for obtaining MR images of both breasts.Women with a recent diagnosis of breast cancer by mammogram (X-ray examination of the breasts) may benefit from MRI of the breasts as MRI may detect additional breast cancers.

Breast cancer is the most common cause of cancer death among women. Yearly around 12,500 Dutch women are diagnosed with breast cancer and 3,500 die of this disease. One of the problems leading to such striking effect refers to late tumor detection due to inadequate sensitivity of current imaging techniques. Current screening is performed by means of mammography, consisting of traditional film-screen mammograms of digital mammograms. These digital mammograms offer digital enhancement to aid interpretation, which is especially helpful in women with dense breast tissue. Screening mammography is nowadays the single most effective method of early breast cancer detection. For screening of high risk individuals, increasingly the magnetic resonance imaging (MRI) technique is emerging. However, none of the above mentioned techniques has an optimal sensitivity and specificity, leading for instance to a significant portion of false positive results. The clinical consequence of this error is that additional tests and procedures are performed in women who may not have cancer. In the United States, for example, 11% mammograms require additional evaluation; the lesion turns out to be benign in more than 90% of cases [1]. False-positive readings False positive readings are more common in younger women, both because the tests are less specific and because breast cancer is less common [2,3]. As a result, more follow-up procedures, including invasive procedures such as biopsies, will be done in younger women even though fewer cancers will be found. Furthermore, because breast cancer screening occurs repeatedly, the risk of a false-positive study is likely to rise with repeated screening [4]. Emerging adjuncts to mammography include ultrasonography, which is helpful for further assessment of known areas of interest, and magnetic resonance imaging. Image-guided biopsy - directed by ultrasonography or stereotactic mammography views - plays a critical role in histological confirmation of suspected breast cancer.
