Filter by:The goal of this prospective, observational study is to investigate the clinical, psychosocial, and patient satisfaction outcomes of patients who undergo perforator flap reconstruction for breast reconstruction and/or vascularized lymph node transfer (VLNTx) for the treatment of lymphedema. The investigators hypothesize that (1) perforator flap breast reconstruction will result in excellent clinical, psychosocial, and patient satisfaction outcomes compared to non-perforator flap breast reconstruction; (2) perforator flap breast reconstruction is associated with less persistent postsurgical pain than other forms of breast reconstruction, even after controlling for major cofactors, such as the extent of auxiliary lymph node dissection and the use of radiation therapy; (3) perforator flap reconstruction for the treatment of Lymphedema (i.e., VLNTx ) will result in the reduction of symptoms and complications of lymphedema.
The objective of this study is to define the clinical significance of mechanistic biomarkers (including Neuregulin-1Beta) and novel echocardiographic measures of cardiac function in predicting the incident risk of cancer therapy cardiotoxicity.
The purpose of this study is to assess Efficacy and Safety of Extended Adjuvant Treatment With Letrozole in Postmenopausal Women With Hormone Receptor Positive Breast Cancer Who Complete 5 Years of Toremifene
The aim of the CHAT study ("An open-label, randomized Phase II study of Herceptin (trastuzumab), Taxotere® (docetaxel) and Xeloda (capecitabine) in combination, versus Herceptin (trastuzumab) plus Taxotere® (docetaxel), in patients with advanced and/or metastatic breast cancers that overexpress HER2") was to test the combination of Trastuzumab and Docetaxel with or without capecitabine as first-line therapy for HER2 positive locally advanced or metastatic breast cancer. Overall Response Rate was the primary endpoint of the CHAT study. This study failed to meet its primary objective of showing a difference between the treatment groups, with equivalent high response rates for the Trastuzumab plus Docetaxel and Trastuzumab, Docetaxel plus capecitabine arms. Secondary endpoints in the CHAT study were Progression-Free-Survival, Time-to-Progression, Overall Survival, duration of response and safety profile. Whilst analysis of the existing data is consistent with improvement with the triplet therapy, interpretation is compromised by the relatively short median follow-up of 24 months. In hindsight the statistical design was flawed by selection of a sub optimal primary endpoint and consequently data was collected and analysed early in relation to time-dependent endpoints. Beyond CHAT will permit capture of mature data for time-related endpoints. Time-to-Progression and Overall Survival are the co-primary endpoints for the Beyond CHAT protocol. The impact of treatment following the first progression, on survival, will be explored. Time-to-Progression will be defined from the time interval between the date of randomisation and the occurrence of progressive disease under therapy according to RECIST criteria. Overall Survival will be defined as the time from date of randomisation to date of death
The purpose of this study is to compare 5-year disease free survival rate (DFS rate) between the hormone receptor positive breast cancer patients who were added Goserelin to Tamoxifen for ovarian function suppression after neo-/adjuvant cytotoxic chemotherapy and the hormone receptor positive breast cancer patients who were treated with Tamoxifen.
Background: The NCI Surgery Branch has developed experimental therapies that involve taking white blood cells from patients' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. Objective: This study will collect white blood cells from normal volunteers and white blood cells and/or tumor cells, from patients who have been screened for and are eligible for a NCI Surgery Branch treatment protocol. The cells collected from normal volunteers will be used as growth factors for the cells during the period of laboratory growth. The cells and/or tumor from patients will be used to make the cell treatment product. Eligibility: Patients must be eligible for a NCI Surgery Branch Treatment Protocol Normal Volunteers must meet the criteria for blood donation Design Both patients and normal Volunteers will undergo apheresis. Patients will then undergo further testing as required by the treatment protocol. There is no required follow up for normal volunteers. ...
The purpose of this protocol is to provide patients with adequate informed consent to understand that screening tests with minimal health risk will be performed to evaluate their eligibility for a research study. The protocol makes it clear that patients initial visit to the intramural clinical program may include screening studies that are not medically necessary for disease management, but are done purely for research purposes. Patients with a known or suspected diagnosis of cancer, HIV infection, skin disorder or immunodeficiency who are being considered for enrollment in a National Cancer Institute intramural clinical research protocol will participate in this consent protocol. It informs patients of screening tests and procedures involving minimal risk that are done for research purposes only, including blood tests, electrocardiogram, standard X-rays (e.g., chest X-ray), bone films, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine studies. It explains that other eligibility screens that are more invasive and involve greater risk, such as a biopsy, will require separate consent.
