CAN008 Biomarker CD95 Ligand and CpG2 Methylation in Chinese Patients With Glioblastoma

Glioblastoma

This study was conducted on the post-operative tumor tissues from 62 GBM patients. 20 slices are necessary for all the CD95 and CpG2 test in the central lab by the methods of immunisation and DNA methylation.

Patients with recurrent glioblastoma who are planned to receive a second course of radiation are to be included into this monocentric cohort trial. Due to multiple pre-treatments simultaneous combined positron emission tomography (PET) with O-(2-[18F]fluoroethyl)-l-tyrosine (FET) as well as magnetic resonance imaging (MRI) is used for treatment planning and follow-up imaging as it allows for a better distinction between treatment-related changes and viable tumor tissue.

Multi-parametric MRI/Fluorine-18 Fluciclovine PET-CT in Glioblastoma

TumorBrain

Glioblastoma is the most common adult brain tumour with approximately 2000 new cases each year in the UK. Optimal treatment consists of surgery followed by radiotherapy and chemotherapy but despite this survival is poor with only 10% of patients alive at 5 years. Standard imaging (MRI and CT) may not detect the full extent of tumours before treatment and it can be difficult to assess how the tumour is responding to treatment. The study aims to evaluate more advanced imaging techniques to see if they are better at mapping the whole tumour and assessing response to treatment. Two different imaging techniques will be assessed: Positron Emission Tomography - Computed Tomography (PET-CT) uses a mildly radioactive compound injected into the patient which is taken up into brain tumour cells and shows up as a bright spot on scans. Brain tumours affect blood supply and how much fluid is in the brain tissue as well as how freely fluid can move around. Advanced MR imaging known as multiparametric MRI will be used to look at these additional features. This extra information may help improve planning of radiotherapy and assessing how tumours respond to treatment. Twelve adult patients with glioblastoma undergoing radical treatment will be recruited over a 12 month period. Each patient will have standard MR imaging before radiotherapy (after surgery) and 4-6 weeks following completion of radiotherapy. They will also have advanced MRI and PET/CT before, during and after treatment. The aim will be to study if this is feasible and could potentially improve radiotherapy planning and response assessment. Imaging will be interpreted by both imaging and brain tumour treatment experts.

FET-PET and Multiparametric MRI for High-grade Glioma Patients Undergoing Radiotherapy

Glioblastoma MultiformeAnaplastic Astrocytoma1 more

Glioblastoma is the most common malignant brain tumor in adults. The primary treatment consists of maximal tumor removal followed by radiotherapy (RT) with concomitant and adjuvant temozolomide. Tumor recurrence after chemoradiotherapy has previously been shown to be predominantly within or at the margin of the irradiated volume, but distant failure are not rare, especially in patients with MGMT methylation.Traditionally, RT has been planned based on on planning CT with co-registered postoperative MRI, with the addition of a clinical target volume margin of 2-3 cm to account for infiltrative odema. To better characterize the disease, more specific physiological and/or metabolical markers of tumor cells, vascularization and hypoxia measured on multiparametric MRI as perfusion, diffusion and spectroscopy alongside with PET tracer like Fluoroéthyl-L-tyrosine ([18F]-FET) are now available and suggest that aggressive areas, like uptake of PET tracer and vascularity are present outside areas of contrast enhancement usually irradiated. These informations could be incorporated to optimize the treatment of radiotherapy.

Glioblastoma MultiformeAngiogenesis

Bevacizumab has become the standard of care of recurrent glioblastoma based on promising clinical trial results with with response rates up to 50% and progression-free survival up to 9 months. In our study, we set to find the serum angiogenesis biomarkers of bevacizumab response.
