Filter by:Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer deaths in American women. Metastatic disease including metastatic breast cancer unfortunately remains incurable. One reason is due to the inability to develop specific therapies for specific cancer subsets. The use of modern genomic techniques has significantly enhanced our recent understanding of breast cancer biology. Five distinct breast cancer subsets have been recognized, one of which is basal-like breast cancer. Basal-like breast cancer is typically estrogen receptor (ER) negative, progesterone receptor (PR) negative and human epidermal growth factor receptor 2 (HER-2-Neu) negative. This is referred to as triple negative breast cancer or TBNC. TBNC represents a significant proportion of breast cancer patients (10-20%) and has a poor prognosis with no targeted approach to therapy as of yet. Tigatuzumab is a humanized monoclonal antibody targeting a death receptor on the breast cancer cells. Previous studies have shown that combining antibodies with selected chemotherapy agents have induced tumor cell death. The hypothesis of this study is to use tigatuzumab and combine it with Abraxane to serve as a targeting agent in metastatic TBNC patients.
The T and B cells repertoire diversity represent one of the immune defence level which controls the integrity of the organism and determines its ability to recognize and control infectious attacks and development of tumours. The study of the lymphocytes TCR and BCR diversity could permit to better understand how lymphopenia act on overall survival and to improve detection of high risk patients who could benefit of adapted therapies for better care.
As the number of women who survive breast cancer continues to grow, more attention is being paid to their quality of life and the disease's long-term effects. The transition from patient to survivor, also termed the "re-entry transition", can be a very difficult and stressful time. A brief psychosocial intervention delivered at this important transition time may address the challenges that women face at re-entry, facilitating greater adaptation and more optimal recovery. The purpose of the proposed RCT is to test the acceptability and effectiveness of a single-session group psychoeducational intervention led by a multi-disciplinary team on adjustment to survivorship. A randomized controlled trial design (RCT) will be used to recruit 440 women attending the breast clinic at Princess Margaret Hospital in Toronto. Participants will be recruited while completing their adjuvant radiotherapy and those who agree to participate will complete the baseline questionnaire package (T0). They then will be randomized to receive either: (1) standard print material (CRL group n=220); or (2) standard print material and a single session group psychoeducational intervention (INT group n=220). Two weeks following randomization, participants in the CRL group will be given the "Getting Back on Track: Life after Treatment" booklet (current standard care), which includes information on the new health care team, physical side-effects, diet and exercise, emotional and social needs and returning to everyday life. Participants in the INT group will receive the same booklet and will also attend a 2- hour psychoeducational group session facilitated by a multidisciplinary team. Participants in both groups will be asked to complete the questionnaire package again at 3 months (post-1) and 6 -months (post-2) following the completion of cancer treatment. Participants in the INV group will also be asked to rate their satisfaction with the class and provide feedback on the content. The proposed intervention will be one of the few clinical interventions designed to address the service gap in helping women to make the transition from patients to survivors by using a single-session psychoeducational group intervention.
The purpose of this study is to determine the effect of short-term fasting on tolerance to adjuvant chemotherapy in breast cancer patients
This single arm, open-label study will evaluate the efficacy and safety of Herceptin (trastutumab) in combination with a taxane as first line therapy in patients with HER2-positive breast cancer who relapsed after neoadjuvant or adjuvant Herceptin treatment. Patients will receive Herceptin (loading dose of 4 mg/kg intravenously [iv], 2 mg/kg iv weekly thereafter) with 6 3-week cycles of either docetaxel (100 mg/m2 iv every 3 weeks) or paclitaxel (90 mg/m2 every week). Herceptin treatment will be continued until disease progression or unacceptable toxicity occurs.
The purpose of this study is to evaluate the efficacy of a new dose of 500mg Fulvestrant with the standard dose of 250mg in Chinese postmenopausal women with oestrogen receptor positive advanced breast cancer who have failed a prior endocrine treatment.
We will develop and evaluate a community-based approach for disseminating comparative effective reviews (CERs) about breast cancer prevention to African American women. The specific aims of our research, as shown below, will target this population because of persistent disparities in breast cancer morbidity and mortality among this population. Our primary aims are: 1. To evaluate uptake of a community-based strategy for disseminating CERs about breast cancer prevention to African American women based on sociodemographic characteristics, beliefs about medical research, and medical history. We predict that participation in a community forum will be higher among women with greater socioeconomic resources, those who have a family history of breast cancer, and women who have more positive beliefs about research. 2. To evaluate the impact of evidential versus non-evidential content about breast cancer prevention on psychological and behavioral outcomes that include: knowledge of breast cancer risk factors and prevention strategies, communication with individuals in their social and medical network, and distrust of medical research. We predict that women who receive evidential content that is specific for African American women will report greater knowledge about breast cancer risk factors and prevention strategies, will be more likely to discuss breast cancer prevention strategies with individuals in their social and medical network, and will report greater reductions in distrust of medical research compared to those who receive non-evidential content.
Research studies have shown a strong association between cancer and blood clots in the veins (also known as deep vein thrombosis). These blood clots can flow to the lungs (pulmonary embolism) which in severe cases may be life threatening. Studies have demonstrated that increases in microparticles may contribute to the development of deep vein thrombosis in cancer patients. The purpose of this research study is to see if rosuvastatin lowers the number of tissue factor bearing microparticles in the blood (TFMP). TFMP are small particles that are generated from different types of blood cells in the body. In people who have cancer, TFMP are thought to be generated from cancer cells and may represent a risk factor for deep vein thrombosis.
The purpose of this study is to identify the combined impact on bone loss as well as the incidence of bone fractures in women with ER-positive, early breast cancer treated with an AI either as first line therapy or as maintenance therapy after initial treatment with chemotherapy, in real life clinical settings in Greece.
This is a prospective, multicenter, open label, non-comparative trial in Spain. The primary objective of this study is to determine the complete response, defined as no vomiting and no use of rescue treatment, in women with early-stage breast cancer treated with one cycle of Docetaxel-Cyclophosphamide and active therapy for the prevention of CINV (Chemotherapy-induced nausea and vomiting) day 1, 5-hydroxytryptamine 3 (5-HT3) antagonist plus 3 days of dexamethasone. A second step (efficacy phase) is designed to examine the efficacy and tolerability of aprepitant in the second cycle among patients who failed to the previous CINV prevention treatment. The study will focus on early-stage chemonaive breast cancer patients receiving docetaxel-cyclophosphamide and a 5-HT3 antagonist plus dexamethasone for the CINV prevention. The CINV incidence in those patients will be evaluated on the first cycle. All refractory patients, will be asked to participate in the second phase, where aprepitant on days 1, 2 and 3 will be added to their antiemetic regimen. Assuming a drop out of 5%, 212 patients will be included in the study. It is anticipated that around 48 patients will enter the efficacy phase. The duration of the study, from first patient visit to last patient visit will be approximately 21 months.
