Active clinical trials for "Breast Neoplasms"

As cytotoxic agents, DTX and PTX have a narrow therapeutic window. BSA dosing leads to great inter-individual PK variability, which is a major contributor for severe toxicity, especially in East-Asian populations. DTX exposures measured by area under plasma concentration-time curve (AUC), PTX exposures measured by the time above a plasma concentration of 0.05 µmol/L (TC>0.05), are the most biologic effects associated PK parameters for DTX and PTX, respectively, which could positively predict related toxicities such as neutropenia, peripheral neuropathy, etc. So, we conducted a randomized clinical trial to compare the effect on related toxicities and efficacy of PK-guided dosing strategy and BSA dosing strategy.

Breast cancer patients who smoke, are at greater risk for treatment complications. The purpose of this study is to see if the researchers can find ways to help patients who have breast cancer quit smoking. They will compare two ways to help people quit smoking. Some patients will receive varenicline, a prescription medicine also known as Chantix,®. Other patients will receive a placebo drug. A placebo is an inactive substance that contains no medicine. All patients will receive smoking cessation counseling provided by our tobacco treatment specialists. They hope that what the researchers learn from this study will help us improve our smoking cessation treatment program for breast cancer patients.

The investigators hypothesize that exercise in postmenopausal breast cancer survivors will result in an increase in the plasma concentrations of angiostatic factors and a decrease in the plasma concentrations of angiogenic factors. Exercise is expected to result in a circulating angiostatic phenotype that inhibits adipose tissue mass, growth of breast cancer tumor, growth of microscopic residual disease after breast cancer resection, decreases rates of local-regional recurrence, decreases rates of distant recurrence, and increases survival.

The purpose of this study is to assess the efficacy of goserelin plus fulvestrant 500mg comparing with goserelin plus anastrozole as first line endocrine therapy for pre- and perimenopausal HR+ advanced breast cancer.

The investigators address the clinical efficacy of continuing lapatinib treatment combined with vinorelbine after the progression of both trastuzumab and lapatinib treatment compared with vinorelbine alone in HER2 positive metastatic breast cancer patients.

Breast cancer is a heterogeneous disease and can be classified into several distinctive subgroups. Triple-negative breast cancer(TNBC) is defined by lack of estrogen(ER), progesterone(PR) immunoreactivity and lack of human epidermal receptor-2(HER2) overexpression. TNBC comprises around 15% of all breast cancer and is characterized by its aggressive clinical behavior and insensitivity toward available targeted treatment strategies such as endocrine and anti-HER2 therapies.Although TNBC is sensitive to chemotherapy,early relapse with metastatic disease is common and the prognosis is poor. Development Of novel treatment strategies is,therefore,needed and the study of other potential targets in TNBC,like tyrosine kinase receptors,is a topic of interest. Epidermal Growth Factor Receptor(EGFR) is a transmembrane receptor tyrosine kinase that encoded by cell erythroblastosis virus oncogene B1(C-erbB1) and belongs to the HER/Erythroblastosis virus oncogene B(ErbB) family. By several signal pathways,EGFR regulates cell proliferation, differentiation, apoptosis, invasion,and angiogenesis,and serves as a poor prognostic factor.EGFR is overexpressed in a variety of malignancies including TNBC.Gene expression profiling and immunohistochemical studies have indicated that 40 to 60% of TNBCs exhibit EGFR expression and gene amplification was found in 18% of this subgroup,but EGFR mutation was rare in TNBC. By far,the role of gefitinib, an EGFR tyrosine kinase inhibitor(TKI),in the metastatic TNBC has not been identified. Most clinical trials about EGFR TKIs in the breast cancer have one or more limitations including:1) the study population had received heavily pretreatment; 2)the enrolled patients included several subgroups of breast cancer; 3)the expression of EGFR was not clear in the enrolled patients. Here, the investigators launch a prospective clinical trial, and about 50 patients with triple-negative,EGFR positive metastatic breast cancer that have received at least second line therapy will be enrolled. these patients will be treated with gefitinib, the toxicity and effects of gefitinib will be recorded prospectively to evaluate the role of gefitinib in the metastatic TNBC.

Select 600 cases of women with breast cancer of triple negative or Her-2 positive or with more than 4 axillary lymph node metastasis. All the patients were accepted the chemotherapy of Anthracycline and/or Taxane. Divide them into two groups randomly. Then the experimental group will be treated with Xeloda(1000mg/m2,orally,2 times/day) for six cycles (21 days/cycle,each taking two weeks suspending for one week) as Sequential Adjuvant Therapy. And the control group will not receive any adjuvant therapy.Finally the investigators will assess the 5-year disease-free survival, 5 years and 10-year overall survival and safety of using medications.

The purpose of this study is to evaluate the role of metronomic cyclophosphamide in addition to docetaxel in first line therapy in metastatic breast cancer.

The purpose of this study is to evaluate the role of low dose metronomic cyclophosphamide and capecitabine in pretreated metastatic breast cancer.

Gemcitabine plus cisplatin has been proved to be an effective regimen as second-line treatment for metastatic breast cancer patients, especially for those previously treated with anthracyclines and taxanes. Lobaplatin, as the third generation of new cancer drug platinum, has a similar anticancer activity to cisplatin, but less kidney toxicity and gastrointestinal reaction. The purpose of the study is to compare the efficacy and safety of gemcitabine/lobaplatin versus gemcitabine/cisplatin in patients with metastatic breast cancer.
