Filter by:This Phase 3 open-label single-arm study is designed to investigate the safety, diagnostic performance, and clinical usefulness of Gleolan for the real time detection and visualization of meningiomas during tumor resection surgery. The study is planned to run for 15 months with individual study participation lasting for approximately 2 months.
The goal of this study is to propose the first direct comparison of Ga-68-DOTATATE PET/CT or PET/MR and Ga-68-DOTATOC PET/CT in patients with meningioma.
This phase II trial studies how well hypofractionated proton or photon radiation therapy works in treating patients with brain tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells. A shorter duration of radiation treatment may avoid some of the delayed side effects of radiation while providing a more convenient treatment and reducing costs.
9-ING-41 has anti-cancer clinical activity with no significant toxicity in adult patients. This Phase 1 study will study its efficacy in paediatric patients with advanced malignancies.
The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer
KRANIOPHARYNGEOM Registry 2019 will prospectively collect and descriptively analyse data on diagnostics, treatment, and follow-up of patients with craniopharyngioma. In continuation of preceding studies also patients with xanthogranuloma, meningioma, pituitary adenoma, prolactinoma and cystic intracranial malformations will be registered.
Postoperative adjuvant radiotherapy is a key component of comprehensive treatment of meningioma. However, for atypical meningioma after total resection, there is still a huge controversy in patients who need adjuvant radiotherapy after surgery. Many scholars have focused on this problem and carried out some small-scale retrospective studies, but they have contradictory results. Some of the studies found that postoperative adjuvant radiotherapy could not improve the prognosis of patients, but was questioned because the sample size was too small, resulting in insignificant results, while other studies found that postoperative adjuvant radiotherapy can improve progression free survival. A study based on the National Cancer Database found that postoperative adjuvant radiotherapy and gross tumor resection are associated with a good prognosis. A recent meta-analysis enrolled a total of 757 patients and found that postoperative adjuvant radiotherapy reduced the risk of tumor recurrence but did not improve survival time. Our team reviewed the meningioma data in the SEER database and conducted a study previously. The study found that postoperative adjuvant radiotherapy did not improve the overall survival of these patients. The relevant research results were recently published in Frontiers in oncology. We further reviewed and summarized the single-center data of our hospital and found that postoperative adjuvant radiotherapy could not improve the progression free survival and overall survival of patients. Besides, we also performed a meta-analysis and found that postoperative adjuvant radiotherapy had a trend to improve progression-free survival, but there was no statistical difference. Because there are many deficiencies in previous researches, and the research results are also contradictory, it is still unclear whether patients with atypical meningioma who have undergone gross total resection can benefit from postoperative adjuvant radiotherapy. Further high quality clinical trials is still needed to be conducted in order to guide the postoperative care of patients. Therefore, we intend to conduct this multicenter randomized controlled trial to determine the value of postoperative adjuvant radiotherapy in patients with atypical meningioma who underwent gross total resection.
Meningioma, an extra-axial brain tumor developed at the expense of meninges, accounts for 35% of central nervous system tumors, and its incidence is estimated at 3% in large autopsy series. The current gold standard for screening and monitoring cerebral meningiomas is MRI with injection of gadoline-contrast product. However, the use of some of these products is problematic, due to gadolinium deposits observed in patients who have had several injections during their lifetime, especially in patients followed for multiple sclerosis. Recently, the French National Agency for the Safety of Medicines and Health Products (ANSM) issued recommendations concerning the screening of meningiomas in patients at risk, particularly in people treated with cyproterone acetate. It is a synthetic progestogen steroid with anti-androgenic properties. It is used to treat hyperandrogenic syndromes in women or in the palliative treatment of prostate cancer in men. Its long-term use seems to be associated with a significant over-risk of developing meningiomas, brain tumours affecting meninges. This increased risk is multiplied by 7 in women exposed to high doses of cyproterone acetate, and by 20 over a cumulative dose of 60 grams, or about 5 years of treatment at 50 mg/day or 10 years at 25 mg/day. The ANSM recommends that a cerebral MRI be performed at the beginning of treatment for all patients, as well as a control MRI renewed at 5 years and then every 2 years if the MRI at 5 years is normal. These recommendations will lead to a large number of MRIs involving an injection of contrast agent in this population, with potential immediate or delayed serious adverse effects. New techniques, such as Arterial Spin Labelling (ASL), or black blood sequences optimized for contrast detection, have been developed. These could detect meningeal anomalies and more particularly meningiomas without contrast injection, or with a significantly lower dose of contrast agent. These techniques have not been specifically studied for screening or monitoring meningeal lesions, but it seems relevant and important to be able to validate protocols that reduce gadolinium doses given the high number of screening and follow-up MRIs in the general population. Patients presenting for brain MRI for meningioma screening or follow-up will have the usual MRI sequences for their management, and the FABIR sequences without injection, added for research. These new sequences will add approximately 8 minutes of additional examination time.
