Active clinical trials for "Breast Neoplasms"

This study will collect information on the height and weight of women who participated in a 1998 study in Triana, Alabama, on the risk of breast cancer and benign breast disease in relation to environmental exposure to the pesticide DDT and similar chemicals. This additional information is needed to calculate the participants' body mass index (BMI), which is required for completing analysis of the data. The 1998 study-a collaborative effort of the National Cancer Institute, the Triana Area Medical Fund, and the College of Nursing at the University of Alabama at Huntsville-investigated possible effects of DDT and other compounds on the risk of breast cancer, predominantly among African-American women in the area of Triana, Alabama. The study was initiated as a result of medical findings showing high blood levels of DDT among the local population who had consumed fish from a tributary of the Tennessee River that had been polluted by the discharge over several decades of large quantities of pesticides from a DDT production plant. Women participating in the study had a mammogram, physical examination, breast examination, and blood draw, and completed a questionnaire on diet and lifestyle factors. In order to complete analysis of the data and determine whether there is an association between environmental exposure to DDT and related chemicals and breast cancer risk, additional information on BMI is required.

RATIONALE: Chemoprevention is the use of certain drugs or supplements to keep cancer from forming, growing, or coming back. The use of omega-3 fatty acids may prevent breast cancer. PURPOSE: This randomized clinical trial is studying how well omega-3 fatty acids work in preventing breast cancer in women at high risk of developing breast cancer.

RATIONALE: Diagnostic procedures, such as nipple aspiration, ductal lavage, and breast duct endoscopy, may help doctors detect and assess breast cancer cells early and plan more effective treatment. PURPOSE: This phase II trial is studying how well nipple aspiration, ductal lavage, and duct endoscopy work in assessing cancer cells in women who are undergoing surgery for breast cancer.

This study will collect, analyze, and compare genes and proteins in normal breast tissue with those in various tissues from women with breast cancer to look for changes that are unique to breast cancer cells. Information about these differences may lead to more effective breast cancer treatments with fewer side effects. The study has the following objectives: To define the molecular (genetic and protein) profile of normal breast tissue from pre- and post-menopausal women of different ages and who have had varying numbers of children (or no children), and who are in different phases of the menstrual cycle To define the molecular profile of primary breast tumors and tumors that have metastasized (spread) beyond the primary site To characterize breast cancer stem cells and establish cell lines from the pleural fluid (fluid around the lungs) of women with metastatic breast cancer. (A cell line is a collection of cells that are grown in the laboratory from an original tissue specimen.) The following women may be eligible for this study: Women who are undergoing cosmetic breast surgery that requires removal of some breast tissue (e.g., breast reduction surgery) Women 18 years of age or older who are undergoing a biopsy or other surgical procedure to sample or remove a known or suspected primary or metastatic breast tumor Women 18 years of age or older who are undergoing pleurocentesis, a procedure to remove fluid from around the lung that is suspected or known to be caused by spread of breast cancer Participants undergo the required procedure (e.g., surgery, biopsy, or pleurocentesis) and provide information that may include the following: Age, race/ethnicity Age at first menstrual period (menarche) Age at first pregnancy and age when the first child was born Age at menopause Information about primary breast cancer Family history of breast cancer Information on previous breast biopsies, if any, and hormones taken (birth control pills or hormone replacement therapy), if any Copy of pathology report from procedure (surgery, biopsy, or pleurocentesis)

RATIONALE: Studying quality of life in cancer survivors may help determine the long-term effects of breast cancer and may help improve the quality of life for future cancer survivors. PURPOSE: This clinical trial is studying the quality of life in African-American or Caucasian female breast cancer survivors.

RATIONALE: New imaging procedures, such as enhanced ultrasound may improve the ability to determine the extent of breast cancer. PURPOSE: Diagnostic study of enhanced ultrasound in women who have locally advanced primary breast cancer.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the recurrence of cancer. The use of perillyl alcohol may be effective in preventing the recurrence of breast cancer. PURPOSE: Phase I trial to study the effectiveness of perillyl alcohol in preventing the recurrence of breast cancer in women who have been treated with surgery with or without adjuvant therapy.

This study will examine how the body handles etoposide, a drug used to treat breast cancer. The knowledge gained may lead to more effective use of the drug with fewer side effects in the future. Breast cancer patients who are receiving etoposide as part of their treatment may participate in this study. Patients will have 18 blood samples (about a teaspoon or less each) drawn over a 72-hour period during and after their infusion of etoposide. The initial blood samples cannot be taken from the same intravenous line (small tube placed in a vein) used to deliver the etoposide, so a second line may have to be placed temporarily to obtain these samples.

Chatbots (contraction of "chat" and "robot") are a computer software program that use statistical learning and aim to simulate a conversation by text or voice message. The use of these chatbots was evaluated as part of the increase in therapeutic adherence and information on well-being and mental health. In clinical studies, chatbots are useful in gathering information through questionnaires directly submitted during conversations or through keyword analyzes. There is no longer any delay between the moment the patient notices a side effect, for example, and the moment when the patient announces it during a consultation. The responses given by the chatbot do not constitute medical advice and only provide information on the treatments envisaged or in progress in the context of the management of breast cancer. The main objective of the study is to show that the chatbot Vik's answers to the common questions asked by breast cancer patients about their therapeutic management are at least as satisfactory as answers given by a committee of multidisciplinary doctors

A single-institutional cohort to determine the prevalence of new immunohistochemical panel in advanced triple-negative submitted to neoadjuvant chemotherapy and its association with response and survival.
