Active clinical trials for "Breast Neoplasms"

Patients diagnosed with breast cancer generally have a fairly well prognosis with estimated average survival rates of 73% and five year survival rates of 89% in developed countries. However, women who are obese at the time of breast cancer diagnosis seem to be at risk for a worse breast cancer related and overall survival, as compared to their normal weight counterparts. In addition, weight gain after diagnosis might be negatively associated with prognosis. Weight gain is a common phenomenon among breast cancer patients receiving adjuvant chemotherapy as well as receiving adjuvant anti-hormonal therapy. While sufficient physical activity and limitation of the amount of weight gain is important for all breast cancer patients, it surely is for overweight and obese patients. The recently published national guideline oncological rehabilitation provides exercise goals, for physical training based on the Dutch PA guideline "Nederlandse Norm Gezond Bewegen (NNGB)". It recommends to engage in moderate-intensity exercise (e.g. brisk walking) for at least 30 minutes a day, on at least 5 days a week. For people who are overweight (Body Mass Index ≥ 25 kg/m2) it is recommended to exercise at least 60 minutes at a moderate-intensity level, equal or more than 3 Metabolic Equivalent Task Hours (> 3 MET/h), on at least 5 days a week. However, only 61% of the general population, meets these guidelines (8) and among cancer patients this percentage is even less. This study aims to increase the percentage of overweight breast cancer patients treated with adjuvant anti-hormonal therapy that reaches the goal of the NNGB by the oncological rehabilitation program with 20%.

This non-interventional study aims at assessing the impact of nab-paclitaxel on the clinical outcomes and the health-related QoL (HRQoL) of this heavily burdened and difficult-to-treat population. Notably, the data generated in the context of this study will serve as complementary evidence to that of the tightly and strictly controlled pre-registration clinical trial setting, which is of essential importance especially in patient populations with diseases of complex and heterogeneous biology, such as breast cancer.

Characterization of the driver mutations in an individual metastatic breast cancer patient is critical for many reasons. Effective targeted therapies require identifying genomic alterations in the tumoral tissue. The scarce efficacy of many currently available targeted drugs may be due to the outbreak of resistant clones with different genotype that already present at the initiation of therapy. It is well known the intra-tumor heterogeneity with genetic and non-genetic factors considered as the origin of the tumor cell-clon composition. The acquisition of multiple mutations (driver and passenger), altogether with the stage of differentiation, according to the cancer stem cell hypothesis, confers to the tumor cells clinically important properties, such as resistance to therapies and seeding abilities. Moreover, there is a current challenge in establishing whether the metastatic cells arise from the most aggressive and dominant clone in the primary tumor or the metastasic tissue diverges with substantial genetic changes very early in the evolution of the disease. Primary and metastatic tumor may have a close clonal relationship or evolve in parallel and acquire different genomic alterations. In the real life, it is plausible that both models coexist with different predominance according to the tumoral tissue and etiology. The study hypothesizes that breast cancer metastases and primary tumors could harbor different genomic profiles related to genomic regions of interest in a clinically relevant proportion of metastatic breast cancer patients. Moreover, the genomic aberrations found in the metastatic breast cancer tissue could also be detected in CTCs and circulating free DNA. If true, CTCs and circulating free DNA would be convenient, non-invasive, easily accessible sources of genomic material for the analysis of mutations and other genomic aberrations.

Investigators propose to assess,the safety and tolerability profile (number of participants with adverse events)of bevacizumab (Avastin) when combined with standard chemotherapy as first line treatment of patients with metastatic Breast Cancer.

Bevacizumab plus chemotherapy improves response rates and prolongs PFS when used as first- and second-line therapy for advanced breast cancer. However, bevacizumab has not improved OS in the individual studies currently reported. In Europe, EMA has maintained its indication associated with weekly paclitaxel in first line metastatic breast cancer and more recently with capecitabine based on RIBBON 1 trial's results. The identification of patient subsets that receive the most clinical benefit would enable more specific treatment administration of bevacizumab and allow patients unlikely to benefit the opportunity to seek other treatment modalities. Unfortunately, despite efforts to identify patient subsets with a differential benefit from bevacizumab, no validated biomarkers have been defined. The Avastin cohort is a unique opportunity to investigate various biological and imaging parameters which could be related to clinical benefit of the combination of bevacizumab and weekly paclitaxel in first line metastatic breast cancer in a homogeneously treated population in French cancer centers. This trial will gather the expertise of several translational research platforms of different cancer centers from the UNICANCER consortium.

This non-interventional study will assess the occurrence rate of non-small cell lung cancer, colon cancer, breast cancer, gastric cancer and malignant melanoma in Turkey, and the diagnostic methods and treatments used. Data will be collected over 36 months.

This observational study will evaluate the routine clinical use and the safety and efficacy of capecitabine (Xeloda®) in participants with metastatic or advanced breast cancer. Eligible participants will be followed for up to 24 months.

To identify a panel of circulating miRNA markers which could help identify those breast cancer patients who are most likely to respond well to neoadjuvant and adjuvant chemotherapy, and indeed serve as an overall prognostic factor and stratify patients into risk categories which would further guide their management. Similarly, the investigators aim to identify a panel of circulating miRNA markers which could monitor patient's response to chemotherapy and hormonal therapies. Ideally a suitable panel of markers would show significant changes in expression level in good-responders whilst little or no change would be observed in miRNA expression in non-responders.

Research studies have shown a strong association between cancer and blood clots in the veins (also known as deep vein thrombosis). These blood clots can flow to the lungs (pulmonary embolism) which in severe cases may be life threatening. Studies have demonstrated that increases in microparticles may contribute to the development of deep vein thrombosis in cancer patients. The purpose of this research study is to see if rosuvastatin lowers the number of tissue factor bearing microparticles in the blood (TFMP). TFMP are small particles that are generated from different types of blood cells in the body. In people who have cancer, TFMP are thought to be generated from cancer cells and may represent a risk factor for deep vein thrombosis.

This is an observational follow-up study on the efficacy of 1st-line treatment with Herceptin (trastuzumab) in patients with metastatic breast cancer 7 years after initiation of treatment.
