Active clinical trials for "Breast Neoplasms"

The purpose of this clinical research study is to learn if the clinical effects of combined Chinese herbal medicine with endocrine therapy is better than endocrine therapy alone in improving the quality of life and shrinking and slowing the growth of the cancer in women with breast cancer bone metastasis.

In this prospective study the investigators sought to evaluate the feasibility of using the genomic signature - Genomic Grade Index (GGI) - in routine clinical practice and its impact on treatment recommendations.

The purpose of this study is to evaluate the incidence rate of progression of disease, to describe the diagnostic and clinical management in patients with Metastatic Breast Cancer in the clinical practice in Bulgaria.

Sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) is currently debatable. It is possible that the tumor response to chemotherapy may alter the lymphatic drainage thus causing lower SLN identification rate and higher false negative rate. Further, the response of NAC can be different in each lymph nodes. It is doubtful whether SLNB can accurately predict axillary lymph node (ALN) status after NAC. The aim of this study to determine the identification rate, the false-negative rate, and the accuracy of SLNB after NAC for node positive breast cancer.

This multi-center observational study will evaluate the use of Xeloda (capecitabine) in patients with metastatic colorectal cancer, colon cancer in the adjuvant setting, advanced gastric cancer and breast cancer in routine clinical practice. Eligible patients receiving treatment with Xeloda according to product label will be followed for up to 10 months.

Background: - Breast cancer is becoming more common in Africa. A higher number of cases appear in women under age 35 than in the developed world. However, little is known about the factors that may contribute to breast cancer in Africa. Researchers want to collect information from female patients in teaching hospitals in Accra and Kumasi, Ghana and to compare this information with that obtained from healthy women in the general population. These two hospitals treat most breast cancers in Ghana. The data will provide information regarding factors that predispose to the development of breast cancer among women in Ghana. Objectives: - To identify and study breast cancer risk factors in women in Ghana. Eligibility: Women between 18 and 74 years of age who are diagnosed with breast cancer. Participants will come from teaching hospitals in Accra and Kumasi, Ghana. Women without breast cancer will be identified from the 2010 Ghanaian Census for comparison purposes Design: Participants will answer questions about their health and lifestyle. Height, weight, and waist/hip measurements will be collected. Blood and saliva samples will be collected. Participants will be given a collection kit to collect a stool sample. Treatment will not be provided as part of this study.

The study is designed to assess the accuracy of patient breast reproducibly using the revised BCID. This study would provide data for target verification and quality assurance to eventually allow treatment of breast cancer patients for either a TBB or accelerated partial breast irradiation. The BCID is a low-risk device similar to immobilization devices used routinely in radiotherapy for other disease sites.

Based on fundamental study （in Vitro and in Vivo, Pro. Jianjian Li）， Her2 expression would be changed from negative to positive by cancer irradiation with liner-accelerator at dose 6GY or up. The propose of this study is to reveal the irradiation result on Her2 expression in human breast cancer.

Study Rationale: an accurate breast cancer staging has a great impact in the management of a breast cancer. MRI is considered as the most sensible exam for this staging. However it has a low specificity and it may result in extra testing and stress for the patient, add to costs, and delay treatment. By contrast, Tomosynthesis is performed during the same time than mammography and has a good specificity. Although this modality is very promising, it has not been assessed in a population of consecutive patients. Study objectives: To compare the diagnostic performance of preoperative bilateral Combo mode (MG+Tomosynthesis) versus mammography among women with breast cancer for the detection of additional multifocal, multicentric, and contralateral cancers.

The study will follow a descriptive design involving a survey. Data collection will involve paper based questionnaires. The questionnaires have been developed in conjunction with breast cancer support groups associated with the Irish Cancer Society and patients.
