Filter by:There is some evidence that vitamin D could be used to reduce breast cancer risk. Randomized controlled trials would provide definitive evidence about this effect. However, trials with breast cancer as outcome are expensive and time-consuming. Use of surrogate outcomes has been advocated to accelerate progress in the identification of interventions that could prevent breast cancer. Mammographic breast density is one of the strongest breast cancer risk indicators and is already used as a surrogate outcome in several breast cancer prevention trials. The aim of this double-blind randomized controlled trial is to determine whether daily oral supplementation with vitamin D3 (1,000, 2,000 or 3,000 IU) over a period of 1 year reduces breast density in premenopausal women compared to placebo. A total of 376 women (94 per arm) who live in Quebec City will be recruited. Showing that vitamin D reduces breast density would provide strong support for the idea that vitamin D can be a safe and inexpensive approach for the prevention of 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.
Established in 2010, the Long-term Anastrozole vs Tamoxifen Treatment Effects (LATTE) observational study aims to collect vital long-term safety and efficacy data on anastrozole and tamoxifen, drugs that were taken by post-menopausal women as part of the Anastrozole Tamoxifen Alone or in Combination (ATAC) trial. ATAC was a crucial breast cancer trial evaluating the use of aromatase inhibitors (AIs) in the adjuvant setting, with a median follow-up of over 10 years. The ATAC trial assessed the safety and efficacy of anastrozole+placebo, tamoxifen+placebo and anastrozole+tamoxifen in postmenopausal women undergoing treatment for invasive primary breast cancer
A randomized prospective simple-blind interventional study evaluating the efficacy of the synthetic adhesive solution "Ifabond", in patients undergoing breast cancer surgery. The main objective of this study is to determine if the application of Ifabond, in addition to the conventional method of breast surgery, reduces the postoperative seroma formation. The secondary objective is to assess quality of life immediately after surgery, and the need for needle aspiration of the axilla, when using Ifabond.
This multicenter, randomized, single-blind, placebo-controlled, two arm study will evaluate the efficacy and safety of paclitaxel with GDC-0941 versus paclitaxel with placebo in participants with locally recurrent or metastatic breast cancer.
The main purpose of the investigation is to determine if curcumin reduces NF-kB DNA binding and ultimately its downstream mediator IL-6 in patients receiving XRT for their breast cancer after having completed chemotherapy. Patients who have received prior chemotherapy will be eligible, because we have found that this enriched population is at particular risk for exhibiting increased NF-kB DNA binding and IL-6 following XRT.
This research study is Phase II clinical trial, which tests the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is being studied. It also means that the FDA has not yet approved XL184 for use in patients, including people with your type of cancer. XL184 is a drug that may stop cancer cells from growing. It is a small molecule kinase inhibitor that inhibitors met and VEGFR2, as well as other targets. This drug has been used in Phase I studies in humans and laboratory experiments, and information from those other research studies suggests that this drug may help to slow tumor progression in this research study. This drug has also been used in a phase II study for breast cancer patients (a randomized discontinuation trial) suggesting good benefit for this group of patients. In this research study, we are looking at the anti-tumor effects of XL184 in metastatic breast cancer.
The purpose of this study is to see whether it is feasible to conduct a study to determine if the use of hyaluronic acid (HLA) vaginal gel (HyaloGYN®) improves vulvovaginal health. This study aims to look at whether or not HyaloGYN® is effective in women with a history of hormone receptor positive cancer and experiencing vaginal and/or vulvar symptoms of estrogen deprivation following their breast and endometrial cancer treatment.
A cross sectional study to determine the prevalence of persistent pain after reconstructive surgery after mastectomy for breast cancer, with a comparative analysis of a cohort treated with mastectomy without reconstruction.
This research proposal concerns a study to monitor the effects of chemotherapy on breast cancer tumour and peritumour stromal cells using ultrasound (US) elastography (also known as strain imaging). Many cancer treatments currently being developed are targeted; that is they exploit particular biological processes in specific cancer cell types to disrupt tumour growth. Being able to monitor the efficacy of these typically high-cost drug therapies is essential both for the best patient outcome as well as offering economical benefits to the health care system and much needed insight into future drug development. Ultrasound provides a relatively inexpensive, non-invasive means for imaging cancers, and has been used widely in breast cancer diagnosis for many years. Its role in therapy monitoring has been suggested but has not been well explored. The purpose of this proposal is to explore this potential in more depth. It has been identified that significant interaction takes place between tumour and stroma through all stages of tumour growth; this complex relationship is an ongoing topic of research. Fibrotic changes occur during tumour growth and are also a quintessential process of healing. Indeed, fibrosis is a common after effect to chemotherapy in many forms of cancer. Elastography is an established imaging technique (based on ultrasound or MRI) which can estimate the relative stiffness of tissues in vivo and is thus well-suited to monitor these particular biological processes. This elucidates the main hypothesis of this project: fibrosis, cancer cell necrosis and inflammation may all contribute to a measurable response in elastography. These changes to the tissue composition can be imaged over a course of a patient's treatment to assess the response to chemo/hormonal therapy. The ultimate project goals are to develop a clinical tool (based on ultrasound elastography) to improve treatment management in addition to offering a better biological understanding of tumour/stroma behaviour.
