Filter by:Method: This multicentric prospective cohort is composed of patients with no metastatic breast cancer selected by tumor's genomic analysis and treated by chemotherapy with Anthracycline without Taxanes (6 cycles of FEC 100). The patient can be included before or after the surgery and a written consent must be signed for the proteomic and genomic analysis of the tumor. Patients who have a "good signature" for the genomic analysis will receive the standard chemotherapy. Primary objective: - To compare metastasis free survival at 5 years in a cohort of patients with no metastatic breast cancer, who are selected by their genomic profile of the tumor and received a standard chemotherapy containing Anthracycline, with result of retrospectives studies. Secondary Objectives: - Overall survival. - Creation of a circuit (transport-extraction-genomic analysis-result) which allows the beginning of the chemotherapy within 6 weeks following the primary surgery. - Histological and seric proteomic exploratory studies.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells. Giving it after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying the side effects of radiation therapy and to see how well it works in treating women with early stage breast cancer.
The purpose of this study is to investigate the difference in late radiation morbidity between hypofractionated and standard fractionated breast irradiation given to women operated with breast conservation for early breast cancer.
This study is being done to find out what factors may be related to the risk of getting a second breast cancer among women who already have breast cancer in one breast. It will look at how genes, treatment for breast cancer; including radiation therapy, and the effects of different lifestyle activities, may affect the risk of breast cancer. It will use different processes to find genes that might increase the risk of breast cancer. The results of this study may help to develop better ways to detect, treat and prevent breast cancer. This study will compare women who have breast cancer in both breasts to women who have breast cancer in only one breast.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about nutrition-related changes that identify biomarkers related to cancer. It may also help doctors predict a woman's risk of developing breast cancer. PURPOSE: This laboratory study is looking at nutrition-related biomarkers in predicting breast cancer risk in women.
RATIONALE: DNA analysis of tumor tissue may help doctors predict how patients who receive paclitaxel will respond to treatment. PURPOSE: This laboratory study is evaluating gene expression in predicting response to paclitaxel in patients with breast cancer.
The purpose of this study is to learn why certain drugs stop working in patients.In lab studies, tumors become resistant in several ways. Specific molecules seem to change and this may be why therapy stops working. However, we do not know if the same molecules change in patients. This study is being done to see if they do change. If we learn more about how patients become resistant, we may be able to offer better treatment in the future.
RATIONALE: Screening tests may help doctors find cancer cells early and plan better treatment for breast cancer. It is not yet known whether positron emission mammography is more effective than standard mammography in finding breast tumors. PURPOSE: This phase III trial is studying positron emission mammography to see how well it works compared with standard mammography in women with dense breast tissue or who are at high risk of breast cancer.
RATIONALE: Studying samples of blood and breast tissue from healthy women in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to breast cancer risk. PURPOSE: This research study is looking at breast tissue in women not previously diagnosed with breast cancer who are undergoing fine-needle aspiration.
The purpose of this trial is to investigate the difference in late radiation morbidity between partial breast irradiation and whole breast irradiation given to women operated on with breast conservation surgery for early breast cancer with a low risk of local recurrence.
