Active clinical trials for "Breast Neoplasms"

Cancer patients undergo many different modalities of treatments. Pharmacological treatment should be well understood. The nutritional status is not taken into account when calculating drug's doses and this may have an impact in toxicity and quality of life. The present study proposes to evaluate the relationship between the calculation of pharmacological treatment's doses, the toxicity and the impact on quality of life among colorectal and breast cancer's patients.

The investigators intend to undertake a study to investigate the effect of radiotherapy on deep inferior epigastric perforator flap reconstructions (DIEP). Adjuvant post-mastectomy radiotherapy (PMRT) is offered to women at high risk of chest wall recurrence. The perceived detrimental effect of radiotherapy on an immediate breast reconstruction and the "one-off" nature of autologous reconstruction leads some surgeons to recommend delayed reconstruction after mastectomy or to use a temporising implant with a view to planned exchange to autologous reconstruction after radiotherapy. However, there remains significant uncertainty in the literature about the impact of radiotherapy on autologous reconstructions. This study is a mixed methology study using patient reported outcome measures (PROMS), applanation tonometry (measure of breast compressibility), semi-structured interviews and 3 dimensional photography analysis to compare the aesthetic and impact on quality of life on the following groups of patients: Patient groups: Unilateral skin sparing mastectomy (SSM) with immediate DIEP flap reconstruction and PMRT (cases) Unilateral SSM with immediate DIEP flap reconstruction and no PMRT (controls) Unilateral simple mastectomy, PMRT, and subsequent delayed DIEP flap reconstruction (controls) Unilateral SSM with temporizing implant, PMRT and subsequent conversion to DIEP (controls)

Phase II, Open Label, Randomized, Biomarker Study of Immune-mediated Mechanism of Action of Neoadjuvant Subcutaneous (SC) Trastuzumab in Patients with Operable or Locally Advanced /Inflammatory HER2-positive Breast Cancer (ImmunHER)

AUS/FNAC allows the identification of tumors without axillary tumor involvement, or with low axillary tumor burden, many of which do not benefit from SLNB, in the staging of early breast cancer. Objective: To calculate the negative predictive value of AUS/FNAC in those patients with breast cancer who meet ACOSOG Z0011 criteria.

Breast cancer is one of the most common cancers in China. Even though advances in the field of breast cancer therapeutics, chemotherapy remains the mainstay therapeutic modality. The cytotoxic therapies are generally associated with some immediate or otherwise delayed side effects, such as adverse effects on gastrointestinal, hepatic, renal and hematological systems. The effect of chemotherapy on endocrine system, however, is comparatively less envisaged. Several epidemiological studies show a positive association between plasma thyroid hormones levels and breast cancer risk. Thyroid dysfunction is emerging as a variably common endocrine toxicity of several anticancer drugs. Due to the scarcity of data on the functioning of thyroid gland during chemotherapy in a large scale group, the present study was aimed to investigate the incidence of thyroid abnormity in Chinese women with newly diagnosed breast cancer, and also the effects of chemotherapy on thyroid gland functions or structure in these breast cancer patients undergoing at least four cycles of chemotherapy.

In post-menopause women affected by breast cancer and treated with chemotherapy, overweight and obesity are considered both a risk factors as well as a negative prognostic factors since they increase the risk of early relapse and death. Furthermore, a decrease in weight may also occur during chemotherapy and is associated to a reduced quality of life and survival. Also, the majority of patients under chemotherapy refer dysgeusia, an alteration in taste that can determine food aversion, selection of hypercaloric food or reduced food introduction up to malnutrition. Our aim is to evaluate eating habits changes in patients affected by breast cancer and under chemotherapy treatment and to better understand how this alterations influence the quality of life, anxiety, depression and insomnia of patients as well as overall survival.

The value of sentinel lymph node biopsy (SLNB) in patients underwent neoadjuvant chemotherapy is controversial. Lower detection rate and higher false negative rate are the main problem. The purpose of this study is to determine the detection rate and the false negative rate of SLNB by indocyanine green (ICG) in addition to blue dye (methylene blue) after neoadjuvant chemotherapy in patients with large or locally advanced breast cancer. This is a single arm clinical trial.

Evaluate the "Bouge" digital program (smartphone application) to increase the daily physical activity of breast cancer patients

Breast cancer, the first female cancer, affects one in eight women in her lifetime. The increase and unequal distribution of its prevalence throughout the world, regardless of age and genetic factors (< 10% of cases), observations in migrant women and the increased risk in women who have been exposed in utero to diethylstilbestrol, suggest the involvement of environmental factors that can act very early in development, such as persistent chemical pollutants (POPs) that are endocrine disrupting (EP) acting via nuclear receptors. But the demonstration of the deleterious role of such exposure to chemical pollutants is confronted epidemiologically with methodological difficulties: the correlation is most often sought at the time of cancer discovery when the critical windows of exposure are for the breast, fetus, perinatal, peri-advertising or pregnant and a single pollutant is usually measured, whereas they can be potentiated ("cocktail effect"). The objective of this project is therefore to assess the risk related to pre- and per-gravidic exposure to a range of POPs families (dioxins, dioxin-like, PolyChlorinated Bysphenyls PCBs, flame-retardant polybrominated compounds, waterproofing perfluorinated compounds and several organochlorine pesticides), to develop breast cancer within 15 years of delivery, taking into account the conventional risk factors for breast cancer. This project benefits from a historical bio-bank of 6242 cord blood, an indirect reflection of the pre and per-gravidic maternal exposure, a bank set up between 2002 and 2005, during a PHRC at the Nice University Hospital, frozen and stored under strict and regulatory conditions, declared to the CNIL, and the Cancer Observatory / CRISAP of the PACA-Corsica region, with an exhaustive register of over 92% since 2005, and containing the main characteristics of cancer. The cross-referencing of these two registers (biobanks and CRISAP), supported by the preliminary feasibility study (155 cases of cancer expected, 35% of controls lost to follow-up or opposed to participation), makes it possible to consider a prospective case-control study nested in the cohort of mothers included in the bio-bank. It will therefore be investigated whether women parturient women of this period who had the highest levels of POPs cord blood between 2002 and 2005 had a higher risk of developing breast cancer than those who had the lowest levels, taking into account other known risk factors. The assays will be carried out by LABERCA in Nantes, the national reference laboratory, using gas chromatography/high-resolution mass spectrometry coupling. Blood lipid concentrations will be described in quartile and analyzed in continuous values, alone or in combination with a cumulative score, in N=140 cases and 2N=280 controls, matched for age and parity at birth by random drawing, sample required for 80% power, risk 5% OR at 2, frequency of exposure>70%. The investigators propose to develop a predictive model of breast cancer occurrence based on exposure to endocrine disrupters measured during pregnancy by adjusting for known breast cancer risk factors. These conditions should provide information on the possible association of exposure to POPs present in the domestic environment during critical pre- and per-gravidic periods and the risk of breast cancer and reinforce the relevance of preventive measures recently recommended during pre-conceptional and/or pre-natal consultations.

MicroRNA (miRNA) is a type of endogenous non-coding RNA. They are responsible for post-transcriptional regulation and participate in many vital biological processes. Expression profiling has shown that miRNAs can distinguish between normal breast and tumor tissues. In recent years, circulating miRNAs have become promising biomarkers based on their stability and their non-invasive testing and feasibility in clinical practices.
