Filter by:The Stupp protocol is the standard treatment of glioblastoma multiform (GBM) which prognosis remains poor. The non-dividing nature of normal brain cells provides an opportunity to enhance the therapeutic ratio by combining radiation with inhibitors of replication-specific DNA repair pathways such poly(ADP-ribose) polymerase (PARP) inhibitors, thus inducing more cytotoxic effects of DNA-damage related to treatment modalities, including alkylating reagents like temozolomide (TMZ). Olaparib, a potent PARP inhibitor, overcomes apoptotic resistance and sensitizes GBM cells for death receptor-mediated apoptosis induced by TRAIL (Tumor necrosis factor-Related Apoptosis Inducing Ligand). Moreover, inhibition of PARP activity increases cellular sensitivity to ionizing radiation: it was even suggested to be more pronounced in tumors than in normal tissue. Lastly, progress in technical imaging and intensity-modulated-radiotherapy (IMRT) techniques provide new possibilities for sparing healthy tissues.
Temozolomide is the standard adjuvant chemotherapy of newly-diagnosis malignant gliomas.Cisplatin , a kind of chemotherapeutics, can enforce the anti-tumor effects of TMZ. Up to now, the prognosis of recurrent gliomas is very pessimistic and the standard treatment procedure has not been established yet. The prospective,multicentre phase II clinical study is to evaluate the efficacy and safety of TMZ and CDDP in patients with recurrent malignant gliomas
Malignant gliomas are aggressive tumours with poor prognosis despite the current multimodal treatment. Hence, there is a clear need for new, effective therapies, among which immune therapy has emerged as a promising treatment option. When interpreting follow-up magnetic resonance (MR) examinations, the radiologist is often confronted with images that are difficult to interpret with the conventional anatomical imaging techniques. The difference between tumour relapse and therapy-mediated changes is not always distinctive. In this project, the investigators attempt to characterize the inflammatory response with parameters from advanced MRI techniques like MR spectroscopy, MR perfusion imaging and MR-diffusion imaging. These techniques allow characterization of cellular properties like metabolism and tissue structure respectively. Doing so, the investigators will monitor disease evolution in order to timely detect treatment failure, thereby allowing appropriate switch in patient management.
