Filter by:This is a phase II randomized trial that will evaluate the effect of adding LHRH analogue, goserelin, to the standard neoadjuvant chemotherapy to patients with triple negative breast cancer. Targeting LHRH might decrease resistance to chemotherapeutic agents in the neoadjuvant setting and increases clinical and pathological response rates. Additionally, exploring potential surrogate markers (as AR and LHRH receptors) for molecular distinct subtypes of TNBC.
Obesity has been linked to an increased risk of developing a number of malignancies, including postmenopausal breast cancer. One of the established risk factors for breast cancer development in post-menopausal women is obesity which has further been linked to breast cancer recurrence and poorer survival in pre- and post-menopausal breast cancer.
Worldwide, breast cancer is the most incident and prevalent cancer among women. Despite advances in the treatment of advanced breast cancer (ABC) during the past decade, adjuvant systemic therapy has yield little progression for such patients. ABC remains an incurable disease, responsible for approximate 40,000 deaths annually and a median life expectancy of no more than 3 years. The NCCN guidelines clearly define routine adjuvant chemotherapy regimens for the early breast cancer, however, for the patients with recurrence and metastasis, the choice of treatment options is not clear. In this trial, we choose the patients with disease progression who received anthracycline and taxane adjuvant chemotherapy after surgery. The patients received vinorelbine and gemcitabine (NG) or vinorelbine and platinum (NP) regiments for 6 cycles. Then the patients with complete response (CR), partly response (PR) and stable disease(SD) will be assigned to 3 groups, one group will receive the original regiment for 3 cycles to maintain treatment, one group will receive the vinorelbine for 6 cycles, the other group will receive the capecitabine for 6 cycles. Trasuzumab will be used to patients if HER-2 positive. Endocrine therapy will be used if the hormone receptors positive after the chemotherapy. The primary endpoint is to assess disease-free survival (DFS), the secondary endpoint is to assess the overall survival (OS).
Breast cancer is the most common female malignancy in the world, and the leading cause of cancer-associated mortalities among women. Hormone receptors (HR) including ER and PR are the main prognostic factor for breast cancer patients. Breast cancer subtype was defined by ER, PR, HER2 and Ki67 status since the definition of intrinsic subtypes for breast cancer. Breast cancer which ER are positive have less aggressive and better long-term prognoses than other breast cancer subtype. Luminal B1 was definited as ER Positive, PR positive <20%, or Ki-67 ≥20% , and HER2-Negative. Although standard therapy to HR positive breast cancer is endocrine treatment, evidence reported that Luminal B1 breast cancers with lower PR expression are less sensitive to tamoxifen than luminal A breast cancers with higher PR expression, and the specific mechanism is not clear. We previously had a clinically analysed, and we found the Luminal B1 breast cancer had a significant proportion with 38%. Whether we need standard chemotherapy or chemotherapy based intensive endocrine therapy for those patients? In our research, we divided the patients with ER positive, PR negative, and HER-2 negative into two groups. One groups will be treated with 8 cycles of chemotherapy (EC×4-T×4). The other received 4 cycles of chemotherapy (TC×4) then will be given the intensive endocrine therapy (Goserelin acetate+Tamoxifen for young patients/Letrozole for postmenopausal patients). The primary endpoint is to assess disease-free survival (DFS) and overall survival (OS) in different regiments, the secondary endpoint is to assess the expression of female hormone levels. The correlation of the expression of female hormone levels with the clinical outcomes, so that the investigators could optimize adjuvant treatment regiment with luminal B1 breast cancer.
We plan to carry out a prospective, randomized, open phase III clinical trial which sponsored by the Tianjin Medical University Cancer Hospital and Institute. The primary aim is to evaluate pCR of DT and ET regimen as neoadjuvant chemotherapy in the treatment of HER2 negative Luminal B breast cancers and the correlation of pCR respectively with the susceptible gene mutation scores and differential protein identified by proteomics. For patients with pCR, the association between the 5 year DFS and susceptible gene mutation scores and differential protein identified by proteomics will be evaluated. All Non-pCR patients will receive NX chemotherapy for 4 cycles, and to evaluate correlations between 5 year DFS of these patients respectively with susceptible gene mutation scores and differential protein identified by proteomics, and to evaluate the safety of neoadjuvant chemotherapy and sequential adjuvant NX regimen therapy. Meanwhile, we will verify susceptible gene mutation scores and differential protein identified by proteomics are significant predictors of HER2 negative Luminal B breast cancer chemotherapy sensitivity and prognosis, and explore the feasibility of susceptible gene mutation scores and differential protein in clinical application.
Neoadjuvant chemotherapy (NAC) has become the standard therapy for both locally advanced and early-stage breast cancer in recent years for the improvement breast conserving surgery rate and the evaluation of treatment response in vivo. Pathological complete response (pCR) is an independent prognostic factor irrespective of breast cancer intrinsic subtypes after NAC. The trial is designed to compare effectiveness between anthracycline and/or taxane as neoadjuvant chemotherapy for operable advanced breast cancer in different molecular typing. In this trial the investigators will randomly assign 200 primary breast cancer patients to receive six cycles of fluorourcil, epirubicin,and cyclophosphamide(FEC), or four cycles of epirubicin and cyclophosphamide (EC) followed by four cycles of docetaxel(T), or six cycles of docetaxel and cyclophosphamide (TC). Trasuzumab was recommended combining docetaxel to patients if HER-2 positive.The effectiveness of therapy will be estimated after every two cycles of neoadjuvant chemotherapy. Surgery will be performed after completing designated full cycles of neoadjuvant chemotherapy. The primary endpoint is to assess pathologic complete response (pCR, ypT0/is ypN0) rate in different regiments. The secondary endpoint is to assess the relationship between pCR rate with molecular typing in different regiments, so that the investigators could optimize neoadjuvant chemotherapy regiment according to molecular typing.
We aim to assess the quality of life (QoL), and presence and severity of anxiety and depressive symptoms, in women who have had breast cancer diagnosed at ≥1 year, compared to women who did not have cancer. The Clinical Practice Research Datalink (CPRD) primary care database will be used to select a random sample of breast cancer survivors (≥1 year), whose general practitioner (GP) agrees to participate in the study (see below), and who were registered with the practice for ≥1 year before and after the breast cancer diagnosis. Age-matched women who never had cancer will be randomly selected from the same practice. Staff at each practice will mail the study materials to the eligible women, who will complete the questionnaires and send those to the CPRD Intervention Studies Team for processing. Studies of patient reported outcomes (PROs) have been limited by the high cost, time and logistics involved in recruiting patients and processing data. We will evaluate the feasibility of collecting these data using electronic questionnaires rather than paper ones. Thus, nearly half of the participants will receive paper questionnaires, while the others will receive instructions on how to complete the questionnaires online. We will compare the participation rate by each method. In addition, a secondary objective of this study is to assess whether PROs can be reasonably studied by using electronic health records (EHR) or by inquiring the patients' GP, as any of these would involve fewer resources. For this, the EHR of the participating women will be collated from the CPRD primary care database, and the GPs of the participating women will report on their awareness of the patient's anxiety and depressive disorders, or distress for QoL domains; the results of the two sources will be compared to those reported by the patients.
The MARIA breast imaging system is a novel CE-marked radio-frequency (RF) medical imaging device. The system employs an electromagnetic imaging technique that exploits the dielectric contrast between normal and cancerous tissues. The performance and imaging characteristics of MARIA are not yet well demonstrated. The investigators aim to evaluate some aspects of this potentially important new technology.
Background: Internet-delivered interventions (IDI) can provide remarkable opportunities in addressing breast cancer (BC) survivors' unmet needs, as they present an effective strategy to improve care coordination and provide access to efficacious, cost-efficient and convenient survivorship care. Nevertheless, research focusing on this field and aiming at improving survivors´ psychosocial needs is scarce and its practical implementation is limited. Objectives: This study aims at studying BC patients´ and healthcare providers' attitudes towards IDI; exploring BC patients´ unmet support needs and; determining the acceptability, feasibility, efficacy and cost-effectiveness of iACT-BC, a guided internet-delivered individually-tailored ACT-influenced cognitive behavioural intervention designed to improve psychosocial outcomes in BC survivors when compared to treatment as usual. The primary outcomes in this research are anxiety and depression. Secondary outcomes include psychological flexibility, fatigue, insomnia, Sexual dysfunction (SD) and Health Related Quality of Life. Methods: A multimethod research design will be applied and two consecutive studies will be performed. Study 1 will explore participants´ attitudes towards IDI as well as, BC patients' psychosocial unmet needs by adopting an exploratory cross-sectional study design. Study 2 will investigate the effectiveness and cost-effectiveness of iACT-BC in BC survivors, by implementing a two-arm, parallel, open label, multicentre, waiting list randomized controlled trial. Expected Results: It is anticipated that iACT-BC will show to be an effective and cost-effective program in improving anxiety, depression, psychological flexibility, fatigue, insomnia, SD and HRQoL in BC survivors, as opposing to a waiting list control under treatment as usual. The results of this research will be published in accordance with CONSORT 2010 and CONSORT-EHEALTH guidelines and should be available for publication in February 2020.
