Filter by:Epirubicin is a common chemotherapy medication used in the treatment of breast cancer. However, chemotherapy dosing is calculated based on people's height and weight, which may not be the most accurate way. The purpose of this study is to see if epirubicin dosing based on people's genetic profiles is better than the usual methods.
Hormone responsive breast cancer is common and costly. Long-term adjuvant endocrine therapy (AET) improves breast cancer outcomes greatly, but, unfortunately, is commonly associated with physical and emotional concerns. I propose to evaluate the feasibility and preliminary effectiveness of a behavioral intervention to facilitate problem identification, provide education, coaching for breast cancer survivors with symptoms while on AET. Therefore, the intervention intends to empower women to engage in better self-care and seek out resources they need, which, in turn, will lead to better symptom management.
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.
In this study we propose to explore the efficacy of massage therapy combined with meditation in women recovering from tissue reconstruction after mastectomy for breast cancer. Patients will be randomized into 2 groups. The first group will consist of massage therapy on 3 consecutive days starting on the 1st day after surgery. The second group will consist of massage therapy combined with meditation for 3 consecutive days starting on the 1st day after surgery. The effect of massage and massage combined with meditation on stress, anxiety, relaxation, insomnia, alertness, fatigue, tension/muscular discomfort, pain, mood and energy level will be evaluated by using three different surveys.
Background: - At present, women do not have very accurate tests to inform of them of their personal risk of developing breast cancer. More information on the changes associated with both benign and cancerous breast lesions will help develop better risk information. Researchers have been looking at cells found in breast milk to study genetic changes related to breast cancer. However, most of these cell samples have been collected from white women. A new study wants to collect breast milk samples from African American women for further research. Comparing the results of genetic tests will help improve understanding of breast cancer risk in all women. Objectives: - To study genetic changes related to breast lesions, including breast cancer, in African American women. Eligibility: - African American women at least 18 years of age who are nursing a baby and who either have had or are being considered for a breast biopsy. Design: - Participants will be screened with personal health questions. - Participants will receive a box with sterile bottles for milk collection. They will collect two breast milk samples, one from each breast. They will also fill out a questionnaire about their medical history. - The box with the samples and the questionnaire will be returned to the clinical center for study. - After the box is returned, participants will be asked to provide a copy of the biopsy report for any breast biopsies they have had. - There will be a followup phone call every year. Participants will provide health history information. This information will include whether they have been diagnosed with breast cancer in the previous year.
The study will assess the efficacy of LA-EP2006 compared to Peg-Filgrastim with respect to the mean duration of severe neutropenia during treatment with myelosuppressive chemotherapy in breast cancer patients.
This study is proposed to assess long-term Quality of Life issues in breast cancer survivors by measuring the impact on the quality of life made by the structured "Change Cycle Work Shop" coping class as compared to current local standard of care programs. It has been shown that breast cancer treatment can have long-term bio-psychosocial consequences. Specific evidence-based interventions are needed to address Quality of Life concerns in order to improve the overall outcome of breast cancer and its treatment beyond the focus on mortality rate.
This is a multicenter, post-authorization observational with prospective follow-up (EPA-SP) study. Will be involved 137 metastatic breast cancer patients or metastatic colorectal cancer. The hypertension will be evaluated as a predictor of efficacy of bevacizumab associated with chemotherapy, in terms of progression-free survival (PFS) (Main endpoint). The duration of the study will be approximately 42 months.
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.
Axillary dissection is the standard treatment for breast cancer patients with positive nodes. However, seroma formation after axillary dissection remains the most common early complication to breast cancer surgery. It can delay the initiation of adjuvant therapy, predispose to wound infection, delay wound healing and has also been linked to arm lymphoedema. Based on some studies and our experience that vacuum assisted closure （VAC）is effective in complex wound failures following axillary dissection and groin dissection, we use VAC to prevent seroma formation after extensive axillary dissection. This study is aimed to evaluate the efficacy, safety and economics benefits of early VAC application on postoperative complications and wound healing after extensive axillary dissection in comparison to conventional suction drain.
