Active clinical trials for "Brain Neoplasms"

The aim of this study is to explore the efficacy and toxicity of icotinib combined with WBRT in treating patients with multiple brain metastases from NSCLC.

The Radiotracer 18F-FLT can non-invasively assess excessive cell growth in PET scan images. Tumour growth rate is a useful indicator of tumour aggression and response to treatment. Imaging and measuring the cell growth with 18F-FLT may be useful in monitoring response to anticancer treatment.

The purpose of this study is to estimate the rate of local control at the treated site of the metastasis as a function of 1mm versus 3mm expansion about the gross tumor volume (GTV). Each lesion, not each patient will be ranndomized to either the 1mm or 3mm margin with 40 lesions randomized to each arm.

RATIONALE: Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase I/II trial is studying the best way to give proton beam radiation therapy and to see how well it works in treating patients with low grade gliomas.

This protocol describes a study to gain experience in the use of Clevidipine for perioperative blood pressure control in patients undergoing craniotomy for brain tumor or epilepsy focus resection. The purpose of this study is to establish the efficacy of Clevidipine for intraoperative blood pressure control in patients undergoing intracranial procedures, and gather information on the dosage and adverse effects of Clevidipine in neurosurgical patients. This initial pilot experience serves to familiarize the investigators with the use of this drug prior to initiating a planned randomized trial versus institutional standard-of-care therapy. The investigators will obtain greater familiarity with the dosing of clevidipine in this patient population and collect information on the incidence of adverse effects.

The purpose of this study is to: Find out how safe and effective (by monitoring the good and/or bad effects) treatment with high dose temozolomide, thiotepa and carboplatin with stem cell rescue followed by 13-cis-retinoic acid has on children and adolescents with recurrent/refractory brain tumors Find out how the body uses 13-cis-retinoic acid by studying the your blood levels and proteins in the blood that break down the 13-cis-retinoic acid Determine how well 13-cis-retinoic acid penetrates into the spinal fluid.

The purpose of this study is to test the effectiveness of perifosine in preventing further tumor growth using the established optimal dose of the drug. A second goal is to determine if perifosine can block the molecules in the tumor that drive it to divide and grow.

This study has been designed to compile information on the efficacy of the GliaSite RTS combined with radiosurgery in the treatment of newly diagnosed metastatic brain tumors.

The purpose of this study is to evaluate the potential of [18F]-ML-10 to serve as a non-invasive imaging tool for the early detection of apoptosis in brain metastases in response to radiation therapy, in patients subjected to stereotactic radiosurgery (SRS). Such early detection may improve clinical management of patients with brain metastases, as it may help early identification of non-responders, and subsequently potentially lead to optimization of radiation techniques such as the need for whole brain radiation therapy (WBRT), addition of brain penetrating chemotherapy or an early decision on referral of the patient with non-responsive lesions to surgery or to systemic chemotherapy. The experimental design of the present study aims to evaluate the potential of non-invasive PET examination with [18F]-ML-10, to provide the clinician with an assessment of response early in the course of treatment, via non-invasive molecular imaging of radiation-induced apoptosis. This information on tumor responsiveness is currently available only several weeks to months after completion of radiotherapy.

The study implies a 2 step study design. Patients are enrolled into 3 separate groups for melanoma, breast, and non-small cell lung cancer. In the first step, 21 patients per disease group are enrolled. If >=2 objective responses (SD, PR, or CR) out of 21 evaluable patients are observed, enrollment continues for other 45 patients as a whole, where response will be positively evaluated if >=10 patients will respond. If <2 objective responses out of 21 evaluable patients per disease group are observed, this(ese) group(s) will no longer be treated with temozolomide.
