Active clinical trials for "Breast Neoplasms"

RATIONALE: The amount and type of fat in the diet may affect hormone levels, bone mineral density, and breast density later in life. This may affect the risk of developing breast cancer. Learning about the long-term effects of diet on hormone levels, bone mineral density, and breast density may help the study of breast cancer in the future. PURPOSE: This clinical trial is studying the long-term effect of adolescent diet on hormones and breast cancer risk in women previously enrolled in the Dietary Intervention Study in Children.

RATIONALE: Studying mammograms for breast density changes over time may help doctors predict breast cancer risk. PURPOSE: This natural history study is looking at changes in breast density and gathering health information over time to assess breast cancer risk in women with breast cancer and in healthy women.

RATIONALE: Understanding how nausea or vomiting caused by chemotherapy effects a patient's treatment decisions may help doctors plan better cancer treatment and may help patients live more comfortably. PURPOSE: This clinical trial is studying nausea or vomiting in patients who are receiving chemotherapy for breast cancer or lung cancer.

To better understand the mechanisms leading to lymphedema development in breast cancer survivors, and the implications for potential innovative approaches to the screening, prevention and treatment of this condition.

RATIONALE: Diagnostic procedures, such as PET scans, may help in learning how well hormone therapy and trastuzumab work to kill breast cancer cells and allow doctors to plan better treatment. PURPOSE: This clinical trial is studying how well PET scans work in assessing response to treatment in patients receiving hormone therapy or trastuzumab for breast cancer.

RATIONALE: Questionnaires that assess symptoms caused by cancer and cancer therapy may help improve the ability to plan treatment for patients with invasive cancer to help them live longer and more comfortably. PURPOSE: This clinical trial is studying symptoms caused by cancer and cancer therapy in patients with invasive breast, lung, prostate, or colorectal cancer.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer receiving anastrozole may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors learn more about how anastrozole works in the body. PURPOSE: This research study is looking at the pharmacogenetics of anastrozole in postmenopausal women with estrogen receptor-positive (ER+) and/or progesterone receptor-positive (PR+) stage I, stage II, or stage III breast cancer.

This is a observational study in a real-world setting, not requiring determining a dosage regimen, dose reduction criteria, rest period criteria and withdrawal criteria. The purpose of the study is to investigate the efficacy of eribulin as the first or second line chemotherapy to prolong overall survival and to explore factors affecting the survival in patients with HER2-negative hormone-resistant inoperable or recurrent metastatic breast cancer who scheduled to receive the first or second line chemotherapy in clinical practice in Japan. The total duration of the study will be a maximum of 5 years, consisting of 2-year enrollment period and 3-year observational period; the duration of patient participation will be 3 years. All patients will receive adequate treatment for breast cancer which selected by the primary physician after enrollment using the Japanese Breast Cancer Society Clinical Practice Guideline of Breast Cancer and the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology. Investigators at the investigational sites will enter patient data into an electronic data capture (EDC) system up to the third chemotherapy in the study. The end of the study is defined as the time the last patient completes observational period. Patients will primarily be assessed by overall survival (OS) of the first line chemotherapy.

The purpose of this study is to evaluate the use of a device that helps coordinate the breathing cycle in the radiation treatment of the breast in order to minimize the radiation dose to the normal structures around the breast.

The purpose of this research study is to evaluate the usefulness of the TRAP protein as (1) an early indicator of bone destruction and (2) a tool for assessing the effect of Zometa® in treating symptoms of bone metastases due to breast cancer. Tartrate-resistant acid phosphatase (TRAP) is a protein released into the blood stream as a result of bone destruction caused by metastasis of breast cancer to the bone. Bone destruction causes pain and bone fractures. This study will measure TRAP levels in serum taken from breast cancer patients to see if TRAP levels will be able to predict the effect of Zometa® treatment on bone destruction, pain and bone fractures.
