Active clinical trials for "Breast Neoplasms"

This was an open-labeled, multi-center, prospective, non-comparative study of the safety of Herceptin (trastuzumab) used as an adjuvant therapy in patients with early breast cancer who had previously received antracycline therapy before or after surgery.

This is a prospective examination of ribonucleic acid (RNA) extracted from tumor material of breast cancer patients treated with a neo-adjuvant therapy. The RNA will be analysed for expression of estrogen receptor (ER 1), progesterone receptor (PgR), HER2 and Ki-67 with MammaTyper™. According to the determined values for the individual parameters at least 4 subtypes can be distinguished to date Luminal A-type Luminal B-type HER2-type Triple-negative-type As non-clinical endpoint, the agreement of new subtyping with Immunohistochemical methods will be evaluated. As clinical objective, the 5 year Distant metastasis free survival (DMFS) and Overall survival (OS) will be reevaluated according to the new subtyping.

This research study evaluates the effect of chemotherapy on cognition (thinking) and the brain in people with breast cancer.

The purpose of this study is to determine the effectiveness of surveillance breast MRI compared to mammography alone in women with a personal history of breast cancer

Rationale: Prediction of prognosis in patients with breast cancer is important to determine the indication for adjuvant chemo-, endocrine- and immunotherapy. Apart from the clinicopathological parameters incorporated into the Adjuvant!Online predictive model, the validated 70-gene signature MammaPrint® is predictive of outcome too. MammaPrint® is advised in the current Dutch CBO guideline (2012) for hormone receptor positive, invasive ductal breast cancer in individual cases when there is 'doubt' about the indication for adjuvant chemotherapy based on traditional prognostic factors. In the present study MammaPrint® is used in this CBO 2012 guideline defined group of patients as an additional test for decision-making for adjuvant chemotherapy. Objective: To assess the impact of MammaPrint® on clinical decision making regarding the administration of adjuvant chemotherapy in the CBO 2012 guideline defined group of hormone receptor positive invasive ductal carcinoma patients when there is doubt about the indication for adjuvant chemotherapy based on traditional prognostic factors. The influence of various factors and the impact of MammaPrint® in predefined subgroups will be analyzed too. Data from a national registry regarding adjuvant systemic treatment in patients with similar clinicopathological characteristics in whom MammaPrint® was not used will be obtained to provide a control group. Hypothesis: In the group of patients where national guidelines advocate using systemic therapy but doctors are ambivalent in treating patients with adjuvant chemotherapy, it is hypothesized that using MammaPrint® as an additional test will change the indication for adjuvant therapy in a substantial proportion of patients resulting in at least 10% less patients who receive adjuvant chemotherapy. Thus, in the study group at least 10% less patients will receive chemotherapy when compared to a contemporary group of patients with similar clinicopathological characteristics but without using MammaPrint® Study population: Hormone receptor positive, invasive ductal breast cancer patients when there is doubt about the indication for adjuvant chemotherapy based on traditional prognostic factors. Study design: This is a prospective multicentre impact study.

This multicenter, single-arm observational study will evaluate the clinical benefits of Avastin (bevacizumab) in combination with paclitaxel in first-line treatment in patients with metastatic breast cancer. Patients with metastatic breast cancer who have started Avastin treatment within 6 months prior to study start will also be eligible. Data will be collected from patients for up to 5 years.

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.

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.

The investigators will use integrated PET/MR for the goals below: Use of PET-guided proton MRS (MR spectroscopy) and DCE MRI (dynamic contrast-enhanced MRI) for patients who will receive NAC (neoadjuvant chemotherapy) for breast cancer to monitor treatment response. Use of dynamic and static PET to monitor treatment response for NAC, and to investigate the correlation of PET results versus MRS, DCE MRI. Compare clinical staging by PET/MR and by clinical assessment. On pre-chemotherapy studies, to investigate the association of molecular marker status with the dynamic and static PET, MRS and DCE MRI parameters.

In the REaCT-Vascular Access Her2 negative study, the investigator will use a novel method to allow comparisons of established standard of care vascular access strategies using the "integrated consent model" as part of a pragmatic clinical trial. Determining the optimal vascular access strategy remains an important medical issue for patients, nurses, physicians and society. A novel method to allow comparison of established standards of care is needed as part of an increasing internationally mandated incentive to perform more pragmatic clinic trials.
