Active clinical trials for "Breast Neoplasms"

This study will have great impact and influence in the medical setting as the targeted model that will be derived from this study will be the pioneer in our region. This model will be beneficial in identifying risk factors and its association with the Arab women population. Furthermore, it will bring chemotherapy prevention once the risk factors and the model are established. Risk factors maybe different from those identified in western women by Gail and IBIS Models

This is a single centre, observational and retrospective clinical study. The study group was about all HR positive postmenopausal breast cancer patients who were hospitalized between January, 2008 and October, 2010, and ever accepted AI therapy with the completed follow-up data.

Breast cancer is the most commonly diagnosed cancer in women and its definite diagnose is still challenge for radiologist. This study is going to evaluate multi-b value diffusion weighted imaging in discrimination of breast benign and malignant lesions and explore the diagnostic effect of the combination of multi-parameter. At the same time, pathological specimens of patients will be collected. The relationship between magnetic resonance(MR) parameters and pathology biomarkers will be evaluated. Hope multi-b value diffusion weighted imaging can improve diagnosis for breast lesion and provide the basis for clinical treatment. The fundamental of pathology on MR signal change will be further expounded.

The purpose of this research study is: To test blood for the presence of tumor derived circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA) using an investigational medical device called the LiquidBiopsy®. Using the LiquidBiopsy® platform, recovered cells or DNA can also be investigated to obtain genetic information that may be useful to treating physicians in understanding disease. To test blood for natural killer cells (NK cells), which are part of the body's natural immune defense against tumors. A device called the NK VueTM Kit will be used for this test. The LiquidBiopsy® is a new investigational device. An investigational device is one that is not approved by the United States Food and Drug Administration (FDA). The NK VueTM Kit is an investigational device in the United States but is approved in Canada and South Korea as a class II device. If a tumor is present, very tiny numbers of tumor cells or the contents of these tumor cells can get dislodged from the tumor and swept into the bloodstream. The LiquidBiopsy® device is able to purify the tiny numbers of tumor cells or ctDNA in the blood. Even if a tumor is too small to be found by other means such as an x-ray, it is possible that ctDNA or CTCs may be found in the blood. Genetic information can then be recovered from these cells or DNA to look for genetic changes that are related to the abnormal growth in a tumor. This will potentially allow researchers to study tumor cells or tumor DNA from a blood sample instead of a biopsy sample. This may influence cancer diagnosis, treatment and drug selection in the future. NK cells occur naturally in the body and kill tumor cells. This study will measure the activity of the NK cells in blood. A strong correlation between low NK cell activity and increased circulating tumor cells in blood has been reported.

Despite treatment improvements in breast cancer, a large number of patients still progress to the metastatic stage. Metastatic breast cancer patients have an extremely unfavorable prognosis. Not only efficacy, but also quality of life are in the focus when planning a therapy or therapy sequence for metastatic breast cancer patients. Therapy options include anti-hormonal Therapy, antibody therapies, other targeted therapies and chemotherapies. One of the most effective chemotherapies in the adjuadjuvant and metastatic setting is paclitaxel. However drug handling and its side effects can compromise patients quality of life and can have an impact on the pharmacokinetics of the drug. In metastatic breast cancer patients increasing therapy efficacy and reduction of side effect frequency are considered to be advancements of therapy. One of these advancements is the development of a cremophor free and albumin bound paclitaxel, nab-Paclitaxel (Abraxane), which is thought to have a better efficacy and reduced toxicity profile. Nab-Paclitaxel is approved for the treatment of metastatic breast cancer after a failure of first-line therapy and when antracyclines are not indicated. The SERAPHINA study aims to investigate in the use of nab-Paclitaxel in daily routine and the frequency and perception of side effects. As a non-interventional study, the SERAPHINA Study will assess the patient characteristics and describe the patient cohort, in which nab-Paclitaxel is given. This includes age distribution and characteristics documented by the patients themselves.

This is a prospectively registered database of patients with early breast cancer who will be treated with radiotherapy during surgery. More than 2000 women have already received this treatment in clinical trials. This study will monitor the health status of women who receive this treatment outside of a clinical trial, especially those who might not have been eligible for the original clinical trials. The aim is to confirm the long-term effectiveness and safety of the technique.

Breast cancer is one of the most common malignant tumor in women. About 60% of breast cancer patients are still in premenopausal status at the time of diagnosis in China. It is a multicenter prospective observational study. We will collect basic information, medical history, chemotherapy-related adverse reactions, and the results of hormone, blood lipid, and bone density test before, during and after adjuvant or neoadjuvant chemotherapy. The aim of the study is to evaluate the effect of chemotherapy on ovarian function and fertility and the protective effect of GnRHa. In addition, the collected information of the subjects are analyzed to provide suggestions for the relevant prevention strategy.

Breast cancer is one of the most common malignant tumor in women. About 69.75% of breast cancer women patients in China are over 45 years old. It is a multicenter prospective observational study. We collect the basic information, medical history, chemotherapy-related adverse reactions, and the results of blood lipid and bone density test before, during and after adjuvant or neoadjuvant chemotherapy. The purpose of the study is to investigate the risk factors for hyperlipidemia, cardiovascular disease, and osteoporosis in postmenopausal breast cancer patients before and after chemotherapy, and to assess the risk of future arteriosclerotic cardiovascular disease and osteoporotic fractures. In addition, the collected information of the subjects are analyzed to provide suggestions for the relevant prevention strategy.

Obesity has been linked to an increased risk of developing a number of malignancies, including postmenopausal breast cancer. One of the established risk factors for breast cancer development in post-menopausal women is obesity which has further been linked to breast cancer recurrence and poorer survival in pre- and post-menopausal breast cancer.

The study is to determine the prevalence of potential chemo-response related genes mutation in TNBC patients between pCR and SD/PD group, which achieved after NAC; and to evaluate potential relationship between these gene mutations and NAC-response in TNBC patients.Based on the results,we can further characterize TNBC from a phenotypical and molecular perspective, in order to identify potential new target agents and to individualize the treatment.
