Active clinical trials for "Breast Neoplasms"

This non-interventional prospective study will assess the safety of Herceptin SC (subcutaneous administration) as used in routine clinical practice. Patients with HER2-positive early breast cancer, naive and non-naive of HER2+ treatment who are to be treated in the neoadjuvant and adjuvant setting and scheduled to initiate a treatment with Herceptin SC in routine clinical practice use are eligible to participate. The total study duration is anticipated to be 38 months.

This study is to investigate sex hormones levels of Chinese patients with invasive breast cancer.The aim is to analyze biochemical monitoring results of premenopausal and postmenopausal patients to facilitate determination of menopausal status and propose clinical application.

The goal of this research study is to learn about how dexmedetomidine (a standard of care sedative) affects your immune system (your defenses against cancer) by measuring your white blood cell levels before and after surgery.

The purpose of this non-interventional study is to collect data on the efficacy and safety of Nab-Paclitaxel in the routine application.

The purpose: To investigate the diagnostic accuracy of 18F-FLT PET for the suspicious lesions on mammograms and ultrasound.

Axillary dissection is the standard treatment for breast cancer patients with positive nodes. However, seroma formation after axillary dissection remains the most common early complication to breast cancer surgery. It can delay the initiation of adjuvant therapy, predispose to wound infection, delay wound healing and has also been linked to arm lymphoedema. Based on some studies and our experience that vacuum assisted closure （VAC）is effective in complex wound failures following axillary dissection and groin dissection, we use VAC to prevent seroma formation after extensive axillary dissection. This study is aimed to evaluate the efficacy, safety and economics benefits of early VAC application on postoperative complications and wound healing after extensive axillary dissection in comparison to conventional suction drain.

Background: - At present, women do not have very accurate tests to inform of them of their personal risk of developing breast cancer. More information on the changes associated with both benign and cancerous breast lesions will help develop better risk information. Researchers have been looking at cells found in breast milk to study genetic changes related to breast cancer. However, most of these cell samples have been collected from white women. A new study wants to collect breast milk samples from African American women for further research. Comparing the results of genetic tests will help improve understanding of breast cancer risk in all women. Objectives: - To study genetic changes related to breast lesions, including breast cancer, in African American women. Eligibility: - African American women at least 18 years of age who are nursing a baby and who either have had or are being considered for a breast biopsy. Design: Participants will be screened with personal health questions. Participants will receive a box with sterile bottles for milk collection. They will collect two breast milk samples, one from each breast. They will also fill out a questionnaire about their medical history. The box with the samples and the questionnaire will be returned to the clinical center for study. After the box is returned, participants will be asked to provide a copy of the biopsy report for any breast biopsies they have had. There will be a followup phone call every year. Participants will provide health history information. This information will include whether they have been diagnosed with breast cancer in the previous year.

This pilot study involves very frequent monitoring of breast cancer patient blood levels of hs-cTnT Troponin and n-t-BNP (Brain Natriuretic Peptide) before and after initiation of chemotherapy with either adriamycin or trastuzumab in order to define the kinetics of both biomarkers during the first two cycles of chemotherapy. Cardiac troponins and BNP are frequently elevated after experimental chemotherapy in animal models. Their behavior in humans has been inconsistent, with occasional elevations seen, usually within 30 days of therapy. Assays for troponin with sensitivity into the pg/ml range have now been introduced. A majority of patients greater than age 50 have elevations above the detection limit, compared to only 1-3% with conventional troponin assays, and over 90% of diabetics have elevations above the detection limit. Moreover, augmented release of high sensitivity troponin is detected after exercise or rapid atrial pacing of durations of 10-15 minutes in patients with and without coronary artery disease. This improved sensitivity suggests the potential for detection and monitoring of cardiac damage after cancer chemotherapy. We hypothesized that this new generation of troponin assay would be associated with kinetic behavior suggesting ongoing cardiac damage with anthracycline therapy, and possibly also with trastuzumab.

This research trial studies heavy metal exposure in predicting peripheral neuropathy in patients with stage I-III breast cancer undergoing chemotherapy. Studying samples of blood and urine in the laboratory for heavy metal exposure from patients receiving chemotherapy may help doctors find out whether side effects from chemotherapy are related to heavy metal exposure.

This pilot clinical trial studies comprehensive gene sequencing in guiding treatment recommendations in patients with metastatic or recurrent solid tumors. Studying samples of blood and tissue from patients with cancer in the laboratory may improve the ability to plan treatment.
