Filter by:This study aims to investigate diet, lifestyles, serum metabolomics in relation to breast cancer risk in a nested case-control study including 1,547 postmenopausal women from the Cancer Prevention Study II (CPS-II) Nutrition Cohort. The CPS-II Nutrition Cohort is a prospective cohort study of cancer incidence and mortality among 184,185 men and women, established by the American Cancer Society in 1992. Participants completed a self-administered baseline questionnaire in 1992/1993 including demographic, medical, and lifestyle information. Follow-up questionnaires were sent to living participants in 1997 and every other year to update exposure information and ascertain newly diagnosed cancers. From June 1998 through May 2001, blood specimens were collected from 21,963 women. All participants completed a short questionnaire and provided informed consent at the time of blood draw. Non-fasting whole blood collected from each participant was shipped chilled overnight to a central repository, processed, and frozen in liquid nitrogen at approximately -130 °C for long-term storage. Of the 21,963 women who provided a blood sample, investigators identified 782 postmenopausal women diagnosed with invasive breast cancer between blood draw date and June 2011 who had not been diagnosed with cancer (other than nonmelanoma skin cancer) before blood draw or prior to their breast cancer diagnosis. Controls were 1:1 matched to cases on date of birth, date of blood draw, and race and were cancer free at the date of case diagnosis. Seventeen women who were selected as controls were later diagnosed with breast cancer, at which time they became a case. A total of 1,547 postmenopausal women were included in the breast cancer nested case-control study.
The purpose of this research study is to determine how feasible and accurate identifying and removing specific lymph nodes in the axilla (armpit) after neoadjuvant systemic therapy is when patients present with breast cancer that has spread to lymph nodes in the axilla. The specific lymph nodes removed would be determined at the time of diagnosis. If a biopsy proves that cancer has spread to a lymph node, a titanium clip will placed in it to mark it for future removal. That lymph node will be removed after systemic therapy and compared with the rest of the lymph nodes removed from that region.
This study compares the efficacy (adherence and stage) of four interventions to promote colorectal (CRC) and breast cancer (BC) screenings among women ages 50 to 75. They are: 1. usual care; 2. a TIWeb (tailored intervention Website) 3. a CSC (cancer screening call) and 4. TIWeb + a CSC. This study also compares the cost-effectiveness of the 4 interventions to promote CRC and BC screening among women ages 50 to 75.
Despite advances in mammographic technique, mammography is limited in the detection and diagnosis of breast lesions with respect to sensitivity and specificity. In recent decades, ultrasound has become an essential adjunct to mammography for the further characterization of mammographically detected or palpable lesions or in the diagnosis of patients with dense breasts. However, in spite of defined morphological criteria for the differentiation of benign from malignant lesions, ultrasound of the breast also shows limitations regarding sensitivity and specificity. On the one hand, benign lesions may have one or more malignant characteristics and thus require a biopsy. On the other hand, malignant lesions can also show benign characteristics and thus make an accurate assessment difficult. To overcome these limitations, newer sonographic methods have been developed. These include elastography, color and power Doppler imaging, contrast enhanced imaging and 3D sonography. The application of elastography is based on the fact that cancer has a higher stiffness than healthy breast parenchyma. In addition, cancers are characterized by neoangiogenesis and thus generally show an increased vascularization in color and power Doppler. The detection of neoangiogenesis can be improved by the application of contrast agents. The latter provides both morphological and functional information about tumors, through the study of the contrast agent kinetics. Finally, 3D sonography allows for tumors to be examined in a third, coronal plane. This way, the interaction between the tumor and the surrounding healthy tissue can be better appreciated. The objective of this study is the evaluation of suspicious (classified as BI-RADS 4 and 5) breast lesions by using high-resolution sonography, including elastography, color/power Doppler, contrast agent application and 3D sonography. Both morphological and functional information can thus be obtained. The primary hypothesis of this study is that this multiparametric approach will improve the detection and characterization of breast lesions.
This study evaluates the effectiveness of persuasive direct mail materials coupled with an incentive for increasing breast and colorectal cancer screening among people enrolled in Medicaid. Half of age- and gender-appropriate enrollees received this intervention; the other half received the same intervention 15 months later
The study will consist in an adjustment/adaptation of the "standard EMDR protocol" for cancer disease, and most particulary for women who present a breast cancer and during adjuvant therapy. It will also test the faisability of the research, with a view to adjust the calendar and the ressources to put at disposal for a randomized control trial that follow. This study will also allow to test the need and acceptibility of this new psychotherapy for the patient, and to identify facilitators and obstacles : participation/rejection ratio, inclusion rythm, adhesion of the medical staff about the project
The purpose of this second pilot study is to extend the feasibility demonstrated in NCT02963740 that the intervention achieves high levels of moderate to vigorous physical activity (MVI PA) and modulates risk biomarkers for breast cancer and cardiovascular disease in older, obese sedentary breast cancer survivors who are undergoing moderate calorie restriction.
This study will investigate the influence of systemic adjuvant/neoadjuvant therapy (SAT: chemotherapy +/- anti-HER2 antibodies (trastuzumab +/- pertuzumab) on heart function/rhythm and cardio-respiratory fitness in recently diagnosed breast cancer patients. In some patients, SAT damages the heart (so-called 'cardiotoxicity') and this can have a serious impact on the patient's quality of life and overall survival. It has also been suggested that anticancer therapies may lead to repolarization abnormalities, QT prolongation and autonomic dysfunction, clinically reflected by an increase in HR and a reduction in heart rate variability (HRV). There is a lack of information in the literature regarding the extent and time-course of changes in cardiac function, cardiac rhythm and cardio-respiratory performance ('fitness') in these patients. Moreover, the differential influences of specific treatment regimes (e.g. SAT or SAT plus radiotherapy) and different chemotherapy drugs on cardio-respiratory performance remain unclear. A better understanding of these issues is the primary aim of this study.
Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects for patients. Scalp cooling can prevent or minimise CIA in approximately half of all patients, depending on many factors, e.g. type and dosage of chemotherapy. High rates of success are seen in patients treated with taxanes, up to 80-90%. Previous research has shown comparable results of scalp cooling in docetaxel-treated patients when shortening the post-infusion cooling time (PICT) from the initial standard of 90 minutes to 45- and 20 minutes. A shorter PICT is an advantage for both the patient, who can spend less time in the hospital, as well for the logistics at oncological departments. Paclitaxel and docetaxel are both classical taxanes, that share similar mechanisms of action and have comparable plasma terminal half-life times, therefore it seems plausible that the PICT can be shortened for paclitaxel-treated patients as well.
PROACT will establish the effectiveness of the angiotensin-converting enzyme inhibitor (ACEI) enalapril maleate (enalapril) in preventing cardiotoxicity in patients with breast cancer and non-Hodgkin lymphoma undergoing adjuvant epirubicin-based chemotherapy.
