Filter by:The purpose of this trial is to assess the safety and efficacy of the Xoft Axxent eBx System when used for single-fraction IORT in early stage breast cancer. Hypothesis: IORT using the Xoft Axxent eBx System is no worse (non-inferior) than whole breast irradiation (WBI) when used as stand-alone radiation treatment in breast conserving therapy in women with early stage breast cancer.
RATIONALE: DNA analysis of tumor tissue may help doctors predict how well patients will respond to treatment and plan effective treatment. PURPOSE: This pilot study is studying how well hormone therapy or chemotherapy before surgery based on gene expression analysis works in treating patients with breast cancer. The purpose of this research study is threefold. First, it is to determine if this approach to treatment is acceptable to participants. Second, it is to determine whether it is feasible to use the genetic make-up of your breast cancer cells to predict whether your disease will best respond to chemotherapy or hormonal therapy when given prior to surgery. Third, which is optional, is to determine if the blood levels of Insulin-like growth factor binding protein-2 IGFBP-2 can be used to monitor the response of your breast cancer to the treatment that you receive.
This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer that has spread from where it began in the breast to surrounding normal tissue (invasive). Estrogen can cause the growth of breast cancer cells. Hormone therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving tamoxifen citrate, anastrozole, letrozole, or exemestane is more effective with combination chemotherapy in treating patients with breast cancer.
This randomized phase II trial studies how well hypofractionated radiation therapy (RT) works compared to standard RT in treating patients with ductal breast carcinoma in situ (DCIS) or early invasive breast cancer. Radiation therapy (RT) uses high energy x-rays to kill tumor cells. Giving higher doses of RT over a shorter period of time may kill more tumor cells and have fewer side effects. It is not yet known if hypofractionated RT is more effective than standard RT in treating breast cancer.
This phase II trial studies the side effects and how well radiation therapy works in treating patients with stage 0-II breast cancer. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.
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.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether whole-breast radiation therapy is more effective when given with or without additional radiation therapy to the tumor in treating patients with ductal carcinoma in situ. PURPOSE: This randomized phase III trial is studying breast-conserving surgery followed by whole-breast radiation therapy to see how well it works when given with or without additional radiation therapy to the tumor in treating women with ductal carcinoma in situ.
This randomized phase III trial studies radiation therapy to see how well it works with or without trastuzumab in treating women with ductal carcinoma in situ who have undergone lumpectomy. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether radiation therapy is more effective with or without trastuzumab in treating ductal carcinoma in situ.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about differences in DNA and predict how well patients will respond to treatment and plan better treatment. PURPOSE: This clinical trial is studying blood samples from women with breast cancer or ductal carcinoma in situ who are receiving tamoxifen.
Breast MRI is a fairly new technology, but it has been well studied. It is now used routinely in many patients with breast cancer. It has been shown to be useful in detecting areas of cancer that cannot be seen using other types of scans or tests. The purpose of this study is to see how often MRI can find other areas of cancer in women with one area of breast cancer, and to determine how having the MRI test affects their treatment. The purpose is also to study any areas of abnormality seen on your MRI with special methods that allow the images of your breast tissue and the microscopic analysis of your breast tissue to be compared very carefully. The study also aims to follow women who enter the study over a 10-year period to determine how often the breast cancer comes back.
