Active clinical trials for "Breast Neoplasms"

Genetic polymorphisms of metabolic enzymes may influence the metabolism of Doxorubicin-Cyclophosphamide regimen in breast cancer patients. the investigators want to evaluate the frequency or incidence of the genetic polymorphisms of CYP2C19 and ALDH3A1 in breast cancer patients, and analyze the association between the genetic polymorphisms of CYP2C19 and ALDH3A1 and toxicities in breast cancer patients treated by Doxorubicin-Cyclophosphamide regimen therapy.

The purpose of this study is to evaluate efficacy and safety of CDK4/6 inhibitor Palbociclib in combination with Fulvestrant versus Fulvestrant in female patients with HR+/HER2- advanced breast cancer in a real world setting in China. Primary study endpoint: progression-free survival (PFS). Secondary study endpoints: overall survival (OS), overall response rate (ORR), clinical benefit rate (CBR), objective response duration (DOR) and safety.

Breast cancer triples negatives (TN; 15 % of the cases) are characterized by a high histoprognostic grade, a strong proliferation, a strong metastatic power, and a worse prognosis than the other forms of breast cancer. It is however a heterogenous group for histological and molecular level, but also for evolution. Most of the TN is part of the basal breast cancer subcategory. Until now, the medical treatment is based on chemotherapy. Breast cancers by constitutional mutation of BRCA1 / BRCA2 (5 % of breast cancers) are mostly of basal type and their prognostic seems better that what could be expected from high grade tumours and without hormonal receptors. They would be much more frequent in the TN group. However, at this day, no prospective study was led to estimate this incidence, or to study the intervention of other genes of predisposition, as well to analyse the links between this phenotype and their consequences at the germinal or somatic level, in terms of associated molecular changes and prognosis. The purpose of this study is, on a prospective study, to lead a joined analysis at the germinal level, in search of mutations of the main genes of breast cancer predisposition (BRCA1/2, PALB2, PTEN, PALB2), and at the tumour level (tissue micro-array and transcriptome), by correlating these results to the main clinical parameters. The 5 years relapse-free survival will also be estimated.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research trial studies biomarkers as a predictor of response to trastuzumab in samples from patients with breast cancer previously treated in the NSABP-B-31 trial.

Docetaxel plus Capecitabine in anthracycline-pretreated metastatic breast cancer is a recommended scheme in National Comprehensive Cancer Network (NCCN) guideline. Vinorelbine plus Capecitabine is also effective in Metastatic Breast Cancer (MBC) in some clinical study with small sample.

Condition: patients with breast cancer. Intervention: spiritual support (relaxation + image guided + meditation) or relaxation in three consecutive meetings (day 2, 3 and 4), three days of intervention in the same week. The first day the participants will be evaluated if she meets the needs of the research and will answer questions about their indentification and spirituality. Type of study: intervention Study design: randomized controlled trial Masking: blind study. Randomization: sequence generated by SPSS (Statistical Package for the Social Sciences) version 15, organized in sealed envelopes by another qualified professional. The research ends in 2014 jun.

The aim of the CHAT study ("An open-label, randomized Phase II study of Herceptin (trastuzumab), Taxotere® (docetaxel) and Xeloda (capecitabine) in combination, versus Herceptin (trastuzumab) plus Taxotere® (docetaxel), in patients with advanced and/or metastatic breast cancers that overexpress HER2") was to test the combination of Trastuzumab and Docetaxel with or without capecitabine as first-line therapy for HER2 positive locally advanced or metastatic breast cancer. Overall Response Rate was the primary endpoint of the CHAT study. This study failed to meet its primary objective of showing a difference between the treatment groups, with equivalent high response rates for the Trastuzumab plus Docetaxel and Trastuzumab, Docetaxel plus capecitabine arms. Secondary endpoints in the CHAT study were Progression-Free-Survival, Time-to-Progression, Overall Survival, duration of response and safety profile. Whilst analysis of the existing data is consistent with improvement with the triplet therapy, interpretation is compromised by the relatively short median follow-up of 24 months. In hindsight the statistical design was flawed by selection of a sub optimal primary endpoint and consequently data was collected and analysed early in relation to time-dependent endpoints. Beyond CHAT will permit capture of mature data for time-related endpoints. Time-to-Progression and Overall Survival are the co-primary endpoints for the Beyond CHAT protocol. The impact of treatment following the first progression, on survival, will be explored. Time-to-Progression will be defined from the time interval between the date of randomisation and the occurrence of progressive disease under therapy according to RECIST criteria. Overall Survival will be defined as the time from date of randomisation to date of death

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at tissue samples from patients with breast cancer.

The aim of the study is to assess whether early drainage removal in patients with less than 150ml of lymph in postoperative day 1 can reduce total lymphorrhoea

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This study is looking at genetic susceptibility to cancer and interactions between genes and the environment in patients with breast cancer.
