Active clinical trials for "Neoplasm Metastasis"

This trial will enroll approximately 6,000 patients with recent embolic stroke of unknown source (ESUS). Patients will be randomized to dabigatran or acetylsalicyclic acid (ASA) (1:1 ratio) and have visits every three months. The study doctor may prescribe blinded concomitant ASA for pts with coronary artery disease but this is not mandatory. All Adverse Events (AEs), Serious Adverse Events (SAEs), outcome events will be recorded. The trial will conclude when the required number of stroke events are positively adjudicated which is estimated to take 3 years (including 2.5 years of enrollment).

The purpose of this study is to determine whether adding primidone will improve the metabolism of clopidogrel thereby increasing metabolite levels within the blood stream and platelet response to clopidogrel in patients who were previously found to lack adequate response to clopidogrel. This information could help overcome clopidogrel resistance in patients who are at risk for stroke or transient ischemic attack (TIA).

This open-label, multicenter, non-randomized, dose-escalating phase Ib study with an expansion cohort will determine the recommended Phase II dose and schedule to investigate safety, tolerability, and activity of RO5083945 in combination with cisplatin and gemcitabine or carboplatin and paclitaxel in patients with advanced or recurrent non-small cell lung cancer of squamous histology who have not received prior chemotherapy for the metastatic disease. Cohorts of patients will receive escalating doses of RO5083945 in combination with up to 6 cycles of cisplatin and gemcitabine or carboplatin and paclitaxel. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

The specific purpose of this study is to obtain data on safety and efficacy of combination chemotherapy with Temozolomide and Topotecan in patients with CNS metastases of solid tumors. Up to 35 patients will be accrued over 2-3 years and followed for up to 5 years and will receive 8 cycles of chemotherapy. The primary endpoint is the determinant median overall survival and progression-free survival of this regimen, time to progression of the brain metastases, and assessment of toxicity levels in this regimen.

Primary Objective: To determine if treatment with SRS followed by a HER-2 directed therapy regimen results in a 6-month distant brain relapse rate of less than 30%. Secondary Objectives: Describe the natural history of neurocognitive function for women with brain metastases treated with SRS and HER-2 directed systemic therapy and establish a reference benchmark to generate hypothesis for future design of a phase III trial. Describe patterns of distant brain relapse after SRS for all patients and compare them between (a) patients with 1-3 vs. 4-10 brain metastasis and (b) between patients treated with each systemic therapy regimen Describe patterns of neurologic death Describe patterns of local brain relapse Describe patterns of re-irradiation with WBRT or SRS Describe adverse events

To estimate the presence of hypoxia in individual lesions after radiotherapy in patients with brain metastases from breast cancer as identified by F18 EF5 PET/CT imaging.

The purpose of this research study is to see if a specific kind of MRI can identify small and otherwise undetected abnormal lymph nodes in patients with thyroid cancer who are undergoing surgery. The MRI is called Ultra-Small Superparamagnetic Iron Oxide Magnetic Resonance Imaging (USPIO MRI), and uses an experimental contrast agent (ferumoxytol), to try to identify these lymph nodes. The MRI uses magnetic waves to take images (pictures) of the body and is commonly used in medical testing. Ferumoxytol is FDA approved as an iron replacement product for the treatment of iron deficiency anemia in adult patients with chronic kidney disease. In this research study, the investigators want to see if Ferumoxytol will help to identify very small metastases that are not usually seen on standard MRI scans. If the use of USPIO MRI with the experimental agent ferumoxytol identifies very small metastases in lymph nodes, your surgeon may decide to remove them. After the surgery, the nodes will be stored and then analyzed to assess the ability of USPIO MRI and ferumoxytol to detect cancer in very small metastases in the lymph nodes.

The main purpose of this study is to determine the distribution of 18F Fluorocholine (18F-FCH) in the brain which can help distinguishing radiation-induced scarring from tumor regrowth. In addition, the study will measure levels of 18F-FCH in the blood and (if applicable) in the brain lesion tissue that is removed as part of the planned brain surgery.

An open non-randomized study using biology driven selection of therapies. WINTHER study will explore matched tumoral and normal tissue biopsies and will use a novel method for predicting efficacy of drugs. The aim is to provide a rational personalized therapeutic choice to all (100 %) patients enrolled in the study, harboring oncogenic events (mutations/ translocations/ amplifications, etc.) or not. The total number of patients treated in the study will be two hundred across all participating cancer centers (European countries -France; Spain-, Israel, USA and Canada). All centers will realize the same study independently.

The purpose of this study is to determine the effects of CyberKnife stereotactic body radiotherapy in combination with irinotecan chemotherapy in patients with colon or rectal cancer that has spread to the liver. Conventional radiation therapy has a limited role in the treatment of patients with liver metastases because the radiation doses are limited by liver toxicity. The CyberKnife system is a type of radiation machine that precisely focuses large doses of x-rays on the tumor, so that injury from radiation to the nearby normal tissue will be minimal. It is approved by the U.S. Food and Drug Administration to treat tumors, lesions and conditions anywhere in the body when radiation therapy is required. While the device is no longer classified as "investigational", the best treatment dose and times are still being evaluated. Chemotherapy delivered with radiation therapy can increase the effectiveness of treatment, and may allow for a lower dose of radiation therapy to be utilized, thereby limiting negative side effects. In this study, patients will receive Cyberknife radiosurgery directed to liver metastasis for 3-5 treatments, given every other day. Irinotecan 40mg/m2 will be administered intravenously daily for 3-5 days (5 treatments within 10 elapsed days), and prior to radiation therapy. Patients will have follow-up visits at months 1,2,4,6,9,12,15,18, 24, 30, 36, and every 6 months thereafter for 3 years.
