Filter by:1. to evaluate insoluble fibrinogen particles (iFP), as a tool for harvesting, growing and transferring attachment-dependent cancer stem cells and comparing it to the standard method ( coated plate) . 2. to evaluate whether using iFP for growing CSC can yield better results of isolating and enriching CSCs from fresh tumors than other conventional methods
The purpose of this study is to determine the safety and utility of 5-aminolevulinic acid (ALA) for identifying your tumor during surgery. 5-ALA is not FDA approved at this time. When the investigators remove the tumor from your brain, it is important that they remove all of the tumor and not remove parts of normal brain. Sometimes this can be difficult because the tumor can look like normal brain. In some brain tumors, 5-ALA can make the tumors glow red under blue light. This may make it easier for your doctor to take out all of the tumor from your brain. The purpose of this study is to: - Make sure that 5-ALA helps the doctor remove more of the tumor. - Make sure 5-ALA does not cause any side effects. If you do not want to participate in this study, your doctor(s) will still do their best to remove all of the tumor in your brain. Whether or not you join this study will not change your treatment for your brain tumor.
Malignant gliomas are very aggressive and among the most common of brain tumors. A diagnosis carries with it a median survival of approximately 12 months, with 90 - 95% of patients surviving less than 2 years. The current standard treatment of surgical resection followed by radiation therapy and chemotherapy has not substantially prolonged survival. Dendritic cells (DCs) are immune cells that form part of the mammalian immune system. Their main function is to process antigen material and present it on the surface to other cells of the immune system, thus functioning as antigen-presenting cells.In the present study, DCs were used for antigen presentation of glioma antigens to directly induce a cytotoxic T-cell response. Cytokine-induced killer (CIK)cells are shown to be a heterogeneous population, and the major population expresses both the T cell marker CD3 and the NK cell marker CD56, and is termed NKT cells, which has shown significant anti-tumor activity in both clinical trials and animal studies. Furthermore, CIK cells are able to expand significantly when they are cultured with DCs, and the CIK cells activated by DCs stimulation (DCIKs)have a characteristic which cytotoxic activity enhanced and show increased anti-tumor activity. This study aimed to evaluate the clinical efficacy of DCIK cells treatment combined with DCs following tumor resection and radiotherapy in patients with malignant glioma.
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.
