Filter by:The purpose of this pilot study is to determine the prevalence of markers of chronic and cycling hypoxia and reactive species stress (oxidative and nitrosative) in the breast cancer tumor microenvironment. The study is based around four cornerstone features of the pathologic microenvironment - Hypoxia, Reactive Species (reactive oxygen and nitrogen species), HIF-1 and VEGF, which we term the HRHV axis. Fifty breast cancer patients with planned surgical excision will be administered the hypoxia marker drug, EF5, 24-36 hr prior to surgical excision. EF5 is a non-therapeutic drug and provides no direct benefit to those patients enrolled in this pilot study. Tissues obtained intra-operatively will be snap frozen and subsequently analyzed for EF5 binding. Immunohistochemical analysis of a cohort of immunohistochemical and urine markers that depict the HRHV axis will be examined. The association of the markers with the presence of hypoxia, as determined by EF5 positivity, will be determined. Data from this pilot study will be used to establish the prevalence of markers of the HRHV axis in breast cancer. This information will be crucial for future human trials in which the HRHV axis is therapeutically targeted.
Breast cancer and its treatments can take a toll on the physical and psychosocial well-being of cancer survivors. Few interventions can help breast cancer patients improve their physical strength, stamina, and overall well-being. Developing ways to facilitate PA behavior during chemotherapy for breast cancer are necessary. This trial explores ways that breast cancer patients receiving chemotherapy can learn about and engage in PA during chemotherapy. This trial will also give Southern Alberta breast cancer survivors an opportunity to participate in evidence-based programs designed to facilitate their health, breast cancer recovery, and disease-free survival. The investigators primary hypothesis is that women receiving the PA intervention resource kit will report a more positive change in self-reported PA at the end of chemotherapy treatments when compared to the group receiving standard materials.
To develop a system to manage side effects and adjust chemotherapy dose such that a patient can receive their personal maximum tolerated dose.
The purpose of this study is to compare pre and post Aromatase Inhibitor (AI) treatment serological markers of inflammation and assess for correlation with AI-MS.
This randomized pilot clinical trial studies rosuvastatin in treating women with cardiovascular complications who are undergoing chemotherapy for breast cancer. Rosuvastatin may prevent or lessen cardiovascular complications in patients undergoing chemotherapy for breast cancer
Quality of life under therapy with Aromasin® (exemestane) according to IBCSG (International Breast Cancer Study Group) questionnaire. Change of the endometrium after switching from tamoxifen to Aromasin® (exemestane). Deeper knowledge of Adverse Events during routine administration.
RATIONALE: Acupuncture may help relieve nerve pain caused by chemotherapy. PURPOSE: This randomized clinical trial is studying how well acupuncture works in treating nerve pain in patients with stage I, stage II, and stage III breast cancer who are receiving paclitaxel.
The planned trial compares an anthracycline-free taxane based regimen versus a modern third generation (anthracycline/taxane-based) regimen in HER2/neu non-over expressing tumors. The aim is to define a further anthracycline-free standard and to spare anthracycline toxicity to a patient, who will only have a modest benefit from this compound. Prior to randomization for chemotherapy for all patients with HR positive disease OncotypeDX® will be performed to identify patients who should not receive chemotherapy. Secondary objectives of this trial will be to compare overall survival and toxicity between the two chemotherapy arms, to evaluate survival in the observation arm and to perform translational research regarding prognostic and predictive factors.
The aim of this study is to assess the effects of n-3 fatty acids on taxane-induced neuropathy and neurotoxic inflammatory agents in patients suffering from invasive breast cancer.
The purpose of this study is to identify tumor cells in the bloodstream (Circulating Tumor Cells, CTC's) from patient's with locally advanced or metastatic (stage IV) breast cancer. Analyzing the tumor is helpful in guiding therapy; however, research has suggested that the number of tumor cells found in the bloodstream (CTC's) signifies more aggressive behavior and increased difficulty in eliminating the cancer. This research will help to develop better ways to treat breast cancer which could be tailored to a patient and may be adjusted to a patient's individual needs.
