Active clinical trials for "Brain Neoplasms"

Purpose: Improvement of extent of resection by the use of intraoperatively acquired image data sets to navigate. Better define the role of different intra-operative imaging modalities, used to update the navigational data set, in aiding the surgeon during resection of intra-axial brain lesions. To examine the cost-effectiveness of different intraoperative navigational systems as a function of operative time and Operative time (Surgery including imaging) There is increasing neuro-oncological evidence that extent of resection might have an impact in particular in low-grade lesions.

This is a non-randomized open-label uncontrolled phase II trial evaluating efficacy and toxicity of gefitinib in patients with asymptomatic advanced NSCLC who was benefitted by first line chemotherapy. Patients with stage IV NSCLC who have one or more asymptomatic brain metastasis who was benefitted by first line chemotherapy will receive oral gefitinib 250mg once daily until disease progression or unacceptable toxicity. These patients' direct DNA sequencing of tumor tissue EGFR exons 18-21 will be analyzed The response was evaluated by RECIST criteria after the patient received gefitinib 6 weeks.If the patients present with progress disease of brain metastasis after the therapy of gefitinib, the patients will receive irradiation of brain metastasis.If the response is stable disease,partial response or complete response,he will be examined by brain MRI every 12 weeks.

RATIONALE: Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well pemetrexed disodium works in treating patients with recurrent malignant gliomas, primary CNS lymphoma, or brain metastases.

RATIONALE: Photodynamic therapy uses light and photosensitizing drugs to kill tumor cells and may be an effective treatment for refractory brain tumors. PURPOSE: This phase I trial is studying the side effects and best dose of photodynamic therapy using porfimer sodium in treating patients with refractory brain tumors, including astrocytoma, ependymoma, and medulloblastoma.

The aim of this study was to evaluate the progression time and efficacy of brain tumors in patients with brain metastases from HER2-positive breast cancer treated with Pyrrolidine and Capecitabine combined with brain radiotherapy.

Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER1, HER2 and HER4 receptors. This study is a single-arm, prospective, open label clinical study of pyrotinib plus vinorelbine as the therapy of brain metastases from HER2-positive metastatic breast cancer.

The study will use an Ommaya reservoir that drains into brain metastases to deliver activated, autolous dendritic cells to the tumor lesion, for patients who are 18 - 75 years old who have brain metastases from either lung cancer or breast cancer. The primary objective of the study is to evaluate the safety and feasibility of administering DCVax-Direct to patients with metastatic tumors in the brain. The secondary objectives are to determine tumor response, the rate of intracranial recurrence (IR), the rate of neurologic deaths, decline in neuro-cognitive functioning and overall survival. Approximately 10 patients with injectable metastatic brain tumors will be enrolled initially in a dose escalation scheme, with the expectation to enroll a total of 24 patients.

The goal of this clinical research study is to find out the highest tolerable dose of an imaging solution called 18-F-fluoroacetate sodium that can be given before a positron emission tomography (PET) scan. The safety of this solution will also be studied.

Microneurosurgical resection of intracerebral metastases leads to prolonged survival and relief of symptoms in selected patients. To minimize the risk of intracranial recurrence whole brain irradiation has been established as standard adjuvant treatment in those patients. Sector irradiation resembles a brain - tissue - sparing method by focusing the irradiation in the area of the tumor bed and a surrounding 1mm security margin. The aim of this study is to investigate whether adjuvant "sector""-irradiation following microsurgical resection is equal to adjuvant whole brain irradiation in terms of local control and superior to in terms of quality of life and neurocognitive deficits in a prospective randomized trial.

The purpose of this study is to determine whether EGFR-TKI can control the development of intracranial lesions in Non Small Cell Lung Cancer patients with asymptomatic brain metastases, and the difference in progression free survival between exon 19 and exon 21 mutations.
