Filter by:This pilot clinical trial studies the use of the radiofrequency-guided localization in patients with abnormal breast tissue undergoing lumpectomy (a type of breast-sparing surgery). The radiofrequency identification localization system consists of an implantable radiofrequency identification tag and a hand-held radiofrequency reader to mark abnormal breast tissue before surgery and later surgically retrieve them. Radiofrequency-guided localization may make it easier to find and remove abnormal breast tissue during lumpectomy.
The purpose of this study is to assess efficacy of gonadotropin-releasing hormone agonist (goserelin) on the preservation of ovarian reserve function in young breast cancer patients treated with (neo)adjuvant chemotherapy by serial measuring ovarian reserve markers (AMH and AFC.etc) before and after chemotherapy and long-term pregnancy outcomes. Meanwhile, to evaluate the safety of this protective approach in young breast cancer patients by disease-free survival (DFS) and overall survival (OS) outcomes.
The goal of this behavioral research study is to compare 2 different types of residential group programs to help researchers learn if and how well these groups may help to improve physical and emotional well-being in patients with stage IV breast cancer.
It has been found that the chemical changes that take place in a patient's body during the development of inflammation may provide an environment which stimulates cancer cells. One step in the development of inflammation is the production of certain chemical substances which are important in the formation and spread of tumours. These are called prostaglandins. Cyclo-oxygenase II (COX-2) is an enzyme (a substance that speeds up chemical changes in the body) involved in the production of these prostaglandins and although it is not usually present in most tissues it is made at the sites of inflammation. Celecoxib is a selective Non-Steroidal Anti Inflammatory Drug (NSAID) which works by blocking the action of the COX-2 enzyme, leading to a decrease in the production of prostaglandins and a reduction in inflammation. The purpose of this study is therefore to find out if celecoxib can be used after breast cancer treatment (chemotherapy and/ or radiotherapy) to reduce inflammation and thus reduce the ability of new tumours to grow and survive. 2590 women with primary breast cancer will be recruited in this study from several locations in the United Kingdom and Germany. Eligible patients will be randomly allocated a treatment group, which can be celecoxib or placebo. Both treatments are taken orally (celecoxib 400mg daily, placebo 2 tablets daily) for a total of 2 years. In addition, hormone receptor positive patients will receive endocrine treatment as per local practice. Patients will prematurely discontinue treatment with celecoxib/placebo if disease progression is confirmed or if patients experience unacceptable toxicity. Patients will be seen every 6 months for the first 3 years and then off treatment follow-up is carried out annually. Participating patients will also be given the option to take part in the pathology sub-study by donating a sample of the tumour tissue collected at the time of the primary surgery.
In patients with early-stage breast cancer, chemotherapy has substantially improved survival rates for breast cancer patients. Improvements in outcomes, however, are compromised by the considerable toxicities associated with chemotherapy, most notable being neutropenia. Neutropenia is the presence of abnormally few white blood cells, leading to increased susceptibility to infection and can require hospitalization and need for intravenous antibiotics and is sometimes fatal. Febrile neutropenia can also be associated with treatment delays and dose reductions, potentially compromising treatment efficacy. Patients can receive medication to reduce the risk of febrile neutropenia, such as Neupogen (Filgrastim) as a daily injection for 5, 7, or 10 days. Since there is genuine uncertainty amongst healthcare professionals as to which administration schedule of Neupogen is better, investigators are performing a randomized study in which patients are put into a group by chance to give participants one of three standards of Neupogen daily injection. Neupogen can cost approximately $200 per injection, so if a physician prescribes 10 days for 8 cycles of treatment this can cost $16,000 compared to a 5 day prescription which would cost half this. In addition to cost savings, many patients are not able to give themselves injections on a daily basis and require nursing resources which are utilized at high-cost. This study will use an "integrated consent model" that involves an "oral consent" rather than a written informed consenting process in order to increase the number of patients who may participate while performing a study at a lower cost. While determining the optimal treatment will improve patient comfort and acceptability, using the minimal safe duration of administration may also offer cost savings.
The most important consideration in the design of this clinical trial is to ensure the safe translation of the personalized synthetic long peptide vaccine strategy. The Food and Drug Administration (FDA) dictates that initial studies of biologic therapies be performed in such a way that there is a balance between the potential risks and benefits in individual patients. Consistent with these recommendations, the investigators will target patients with triple-negative breast cancer who do not have a pathologic complete response after neoadjuvant chemotherapy. These patients typically have no gross evidence of disease following standard of care therapy (neoadjuvant chemotherapy, surgery and radiation therapy) but are at extremely high-risk for disease recurrence. Targeting this patient population provides a window-of-opportunity to design and manufacture the personalized cancer vaccines, maximizes the potential benefit from the vaccine as the regulatory networks associated with metastatic disease are not present, and balances risk in this patient population with extremely high risk for disease recurrence but no other treatment options.
The purpose of the study is to assess whether the addition of positron emission mammography will add diagnostic value to magnetic resonance imaging of the breast, in patients with lesions of the breast that are suspicious enough to warrant biopsy, or which have been confirmed as containing cancer cells.
This multicenter, randomized, double-blind study evaluated the efficacy, safety, and pharmacokinetics of atezolizumab (MPDL3280A) administered with nab-paclitaxel compared with placebo in combination with nab-paclitaxel in participants with locally advanced or metastatic triple-negative breast cancer (TNBC) who have not received prior systemic therapy for metastatic breast cancer (mBC). The safety of single-agent nab-paclitaxel has been determined in previous studies of participants with mBC and the safety data to date suggest that atezolizumab can be safely combined with standard chemotherapy agents.
This study was designed to evaluate safety and tolerability of Herceptin as treatment for patients with human epidermal growth factor receptor 2 (HER-2) positive metastatic breast cancer. Frequency, characteristics and severity of adverse events (AE) and serious adverse events (SAE) were followed to evaluate the safety of Herceptin in patients with HER2 positive metastatic breast cancer.
Patients diagnosed with breast cancer generally have a fairly well prognosis with estimated average survival rates of 73% and five year survival rates of 89% in developed countries. However, women who are obese at the time of breast cancer diagnosis seem to be at risk for a worse breast cancer related and overall survival, as compared to their normal weight counterparts. In addition, weight gain after diagnosis might be negatively associated with prognosis. Weight gain is a common phenomenon among breast cancer patients receiving adjuvant chemotherapy as well as receiving adjuvant anti-hormonal therapy. While sufficient physical activity and limitation of the amount of weight gain is important for all breast cancer patients, it surely is for overweight and obese patients. The recently published national guideline oncological rehabilitation provides exercise goals, for physical training based on the Dutch PA guideline "Nederlandse Norm Gezond Bewegen (NNGB)". It recommends to engage in moderate-intensity exercise (e.g. brisk walking) for at least 30 minutes a day, on at least 5 days a week. For people who are overweight (Body Mass Index ≥ 25 kg/m2) it is recommended to exercise at least 60 minutes at a moderate-intensity level, equal or more than 3 Metabolic Equivalent Task Hours (> 3 MET/h), on at least 5 days a week. However, only 61% of the general population, meets these guidelines (8) and among cancer patients this percentage is even less. This study aims to increase the percentage of overweight breast cancer patients treated with adjuvant anti-hormonal therapy that reaches the goal of the NNGB by the oncological rehabilitation program with 20%.
