Filter by:This is a single-center, prospective, single arm phase II study to evaluate the efficacy and safety of nab-paclitaxel plus carboplatin (with trastuzumab for HER-2 positive patients) as neoadjuvant therapy in operable locally advanced breast cancer patients. The primary objective is pCR. The secondary objectives include ORR, 3-yr DFS, OS and safety. The sample size is 30.
This is a phase II, prospective, multi-center, open-label, non-randomized, controlled study. The objective of this study is to prospectively verify the relation of efficacy of neoadjuvant hormonal therapy, and preliminarily explore the clinical value of complementary adjuvant chemotherapy to predict poor prognosis malignant breast cancer after neoadjuvant endocrinotherapy.
The purpose of the study is to compare how treatment with Fulvestrant (FASLODEX) or Anastrozole (ARIMIDEX) effects disease progression for women with locally advanced or metastatic breast cancer who have not had prior hormonal treatment.
The purpose of this study is to assess safety and tolerability of AZD2014 when given in combination with Fulvestrant
The improvement of the healing rates for breast cancer is based to an important part on the consistent use of so-called adjuvant ("supporting ") medicamentous therapies, including chemotherapy. However this success has a price due to still inaccurate knowledge of the individual risk of relapse: a high number of unnecessary therapies are applied (over-therapy!). The invasion factors uPA (plasminogen activator of the urokinase type) and PAI-1 (uPA inhibitor) were described extensively as strong and independent prognosis factors with high clinical relevance for patients with node negative breast cancer. Compared to clinical and pathological factors (further: "traditional factors ") they show better estimation of the relapse risk leading to an avoidance of redundant adjuvant chemotherapy and may thus essentially contribute to the improvement of the quality of life in these women. In this study we aim to evaluate, how large the portion of the patients with early, operable, node negative breast cancer will be, in whom, by improved low-risk identification through uPA/PAI-1, adjuvant chemotherapy can be omitted.
The propose of this trial is to assess the effect of low dose tamoxifen for breast cancer prevention in HRT (Hormone Replacement Therapy)users.
This phase II trial studies how well tivantinib works in treating patients with recurrent or metastatic breast cancer. Tivantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
T-DM1 , which is a highly innovative but also expensive antiHER2 agent consisting in the coupling of the humanised monoclonal antibody trastuzumab with a cytotoxic agent (maytansine derivate) has shown an encouraging antitumor activity evaluated by Recist criteria (35% objective response rate, 44% stable disease, 18% progressive disease) in patients with advanced HER2 positive Breast Cancer pretreated with several cytotoxic drugs, trastuzumab and lapatinib. Rationale I :For TDM1 to be active, the presence of an intact HER2 receptor is "key" since the internalization of the cytotoxic moiety depends on the binding of trastuzumab to the external domain of HER2. The zirconium 89 labelled trastuzumab PET/CT (or HER2 immunoPET/CT) is a non invasive test which shows promise in measuring HER2 expression (extracellular domain) for the entire disease burden and which could identify non responding patients prior to TDM1 administration. Rationale II: As for many such agents, it is desirable to identify early on (here with the use of FDG-PET/CT) which patients are unlikely to benefit from the therapy
The purpose of the study is to evaluate the benefit of adjuvant chemotherapy on overall survival for elderly patients with breast cancer, in a sub group with a high risk of relapse according to Genomic Grade test.
Neoadjuvant (preoperative) chemotherapy is an interesting research tool which allows investigators to test new drugs and/or new schedules with a validated surrogate endpoint, pCR. It also represents an ideal model to evaluate the relationships between treatments and tumor biomarkers. Recent publications have shown that new molecular classifications of breast cancer (intrinsic subtypes) have an important prognostic and predictive value. Using microarrays for gene expression profiling seems to be the best way to perform this classification; nevertheless such assays are not optimally available for common clinical practice. The IHC-based classification systems are still useful, as fresh tissue is not normally available in clinical practice, and has been shown to correlate well with intrinsic classification using gene expression microarrays. Recently the PAM50 gene set provided a risk of relapse score not only in ER-positive, node negative patients (similarly to the Oncotype Dx Recurrence Score) but also in the ER negative disease. Additionally, the PAM 50 assay was highly predictive of neoadjuvant response when considering all patients. This assay added significant prognostic and predictive value to pathologic staging, histologic grade, and standard clinical molecular markers while using an easy technique that can be performed in clinical practice because the qRT-PCR assay can be performed using FFEP tissue. Triple Negative Breast Cancer (TNBC) is defined by a lack of expression of ER, PgR and HER-2. DNA microarray profiling studies have led to the classification of invasive breast carcinoma into five subtypes: luminal A and B, normal breast-like, HER2/neu overexpressing and basal-like subtypes, with clinical implications. Later on, a new subtype, the claudin-low, has been described. Although not synonymous, the majority of TNBCs carry the basal-like breast cancer (BLBC) molecular profile. The triple negative subtype accounts for 11-20% of breast cancer in different studies, whereas in selected cohorts of patients with advanced breast cancer or African-American ethnicity, TNBC may be diagnosed among as many as 23-28%. Patients with TN breast tumors treated with standard chemotherapy have a shorter DFS and OS than non-TNBC, this difference have been shown to be independent from tumor grade, nodal status and treatment in some studies. The peak risk of recurrence occurs within the first 3 years after initial treatment, with the majority of deaths occurring in the first five years. Chemotherapy remains the only systemic treatment option available for TNBC patients. Several studies have shown that TNBC/BLBC is associated with an increased response rate to neoadjuvant chemotherapy when compared with luminal tumors. However, TNBC patients have a significantly decreased DFS and OS in comparison with luminal patients. The largest study exploring response and survival in early stage breast cancer treated with neoadjuvant chemotherapy was reported by Liedtke et al. Although an increase pCR rate was observed among the TNBC patients, they had a shorter lifespan than the non-TN ones. Patients experiencing pCR had an excellent OS regardless of hormone receptor expression, but patients with residual disease had a significantly shorter survival associated with TNBC compared with non-TN ones. This demonstrates that poor OS is derived from chemo-resistant patients (what unfortunately represent > 50% of them). A relevant problem is the differential response to drugs of TN tumors. These tumors are usually treated with multidrug combinations including anthracyclines and taxanes, with pCR´s of 28-32%. Only recently, the results of a few small trials combining platinum salts and taxanes have been reported, with encouraging results (pCR of 44-77%). The taxane-platinum salt combinations have a biological background, since TN not associated BRCA1 mutations are sensitive to taxanes and resistant to anthracyclines and platinum salts are effective in TN tumors probably because a significant proportion of them have functional DNA repair deficiencies. The primary objective of the study is to identify predictors of response to docetaxel-carboplatin in patients with triple negative primary tumors. Response is defined as lack of invasive tumor in breast plus axilla after neoadjuvant chemotherapy (PCR, pathological complete response).
