Filter by:This randomized pilot clinical trial studies how well giving prolonged infusion compared to standard infusion of cefepime hydrochloride works in treating patients with febrile neutropenia. Giving cefepime hydrochloride over a longer period of time may be more effective than giving cefepime hydrochloride over the standard time.
Lung Cancer (LC), colorectal cancer (CRC) and breast cancer (BC) are the major killers in oncology, accounting for about 40% of cancer deaths. Although progresses have been made in the last few years, unfortunately no patient with metastatic disease can obtain a definitive cure. A recent hypothesis is that cancer is driven by a small subpopulation of cells called "cancer stem cells" (CSCs) or "tumor initiating cells" with an unlimited proliferative potential and the ability to reproduce the original human tumor in experimental animal models. These cells are thought to be responsible for the development of the tumor and represent the only cell population able to sustain tumor growth and progression. Therefore, CSCs represent the elective target for new targeted therapies, endowed with high and selective toxicity towards the tumor but harmless towards normal cells. Current technologies allow us to isolate and expand in vitro the CSCs from tumor specimens, testing their sensitivity to different anticancer drugs in a short period of time. Therefore, there is the potential opportunity to identify LC, CRC and BC CSCs.This is a prospective study assessing feasibility of CSCS isolation in LC, CRC and BC. Patients with a previously performed diagnosis of LC, colon cancer or breast cancer with no further standard therapy options, with a Karnofsky performance status of 100% and with tumor tissue available will be considered eligible for the study. Tumor tissue will be collected before study entry, i.e tissue obtained during a diagnostic or therapeutical procedure, like surgery or biopsies with other purposes than the protocol. In vitro tumor sensitivity to chemotherapy drugs will be tested on tumor cell cultures per each patient. Drugs and their combination will be considered effective and if they kill ≥ 60% of tumor stem cells in vitro test. By using cancer spheres the investigators will also generate orthotopic xenograft models that recapitulate the parental tumor behaviour, including the aggressive features and the invasiveness potential. Orthotopic injection technique will be assessed in 5 weeks-old NOD/SCID mice
Risks from imaging-related radiation exposure have become a popular topic in the media. Because these tests are commonly applied to patients at a cancer center, it is important to understand what patients know, how they feel about what they know, where they get their information, and how satisfied they are with available risk-benefit communication on this topic. The purpose of this study is to understand how cancer patients perceive risks and benefits of diagnostic radiation and their satisfaction with healthcare communication on this topic.
Obesity is an epidemic and the majority of breast cancer survivors are overweight or obese. The American Cancer Society has called for weight loss treatment to be standard of care for overweight women with breast cancer. During therapy women with breast cancer often gain weight and lose lean muscle mass. Overweight breast cancer survivors are more likely to have their cancer come back. The reason why overweight breast cancer survivors are more likely to re-occur has not been well studied, but changes in how insulin works may contribute. Overweight survivors are also at risk for the other chronic diseases associated with obesity. Fortunately, weight losses of as little as 5-7% of baseline body weight can improve risk of chronic disease. An effective behaviorally-based, lifestyle intervention delivered via the internet has been developed at the University of Vermont. This successful intervention has not been tested among breast cancer survivors. Given that women tend to lose muscle mass during cancer therapy the addition of a resistance training component to the weight loss intervention may be important. Therefore the overall goal of this project is to pilot test a proven distantly- delivered behavioral weight loss intervention among overweight breast cancer survivors and to evaluate whether a resistance program results in improvements in lean body mass, while studying how both interventions change insulin sensitivity. Specifically, this project is a randomized, controlled clinical trial designed to test the effectiveness and acceptability of a 6-month behavioral weight loss intervention with and without resistance training. Participants will be randomized to one of two groups: 1) behavioral weight control treatment via the Internet; or 2) behavioral weight control treatment via the Internet plus a resistance training program. Women eligible to participate include overweight breast cancer survivors who are age 50 or older and 6-36 months past receiving chemotherapy. Assessments will be conducted at baseline and six months and will include measures of body weight, muscle mass, adherence to treatment, and insulin sensitivity.
The purpose of this study is to compare normalization of vitamin D serum level after 6 months of vitamin D supplementation adjusted to baseline vitamin D serum level vs.conventional vitamin D supplementation.
This observational study will characterize retrospectively patients with HER2-positive metastatic or locally advanced breast cancer who had received treatment with Herceptin (trastuzumab) in 1st line and who were without progression for at least three years. Patients will be followed prospectively for one year.
The purpose of this study is to assess the efficacy, safety, and tolerability of GRN1005 in patients with brain metastases from breast cancer. For patients with HER2 positive metastatic breast cancer, GRN1005 will be assessed in combination with Trastuzumab (Herceptin®) as per standard-of-care practice. In addition, this study will evaluate the ability of 18F-FLT to determine if the amount of change in the uptake in the brain metastases from breast cancer after GRN1005 treatment, correlates with intra-cranial response (for patients enrolled at NCI).
Purpose of this trial: 1. To assess the efficacy and safety of NeuVax™ administered with adjuvant Leukine® (sargramostim, GM-CSF). 2. To evaluate and compare the disease free survival (DFS) in the vaccinated and control subjects.
The scope of this registry study is to measure chemosensitivity as defined by pCR (primary endpoint), or endocrine sensitivity as defined by partial response (decrease in longest tumor diameter or residual cancer burden category 1 (RCB1), a primary endpoint for neo-adjuvant endocrine therapy and a secondary endpoint for neoadjuvant chemotherapy), metastasis-free survival and relapse-free survival(secondary endpoints) in molecular subgroups, determined by the established MammaPrint, BluePrint, Targetprint and Theraprint profiles in addition to possible novel expression profiles.
The purpose of this study is to determine the maximum tolerated dose of veliparib that can be given while a patient is receiving radiation therapy.
