This phase III trial studies stereotactic radiosurgery (SRS) before surgery to see how well it works compared with SRS after surgery in treating patients with cancer that has spread to the brain (brain metastases). SRS is the delivery of focused, high-dose radiation given in a single session to the tumors, with a minimal dose given to uninvolved areas of the brain.
STEP is a French multicentre, prospective, non-randomized, phase II study designed to assess 6-months local control after pre-operative stereotactic radiosurgery (SRS) for patients with brain metastases
This is a phase III randomized trial with the aim to compare preoperative HSRS to postoperative HSRS in patients with large at least one BMs from solid tumors suitable for surgical resection.
The purpose of the study is to determine whether treatment with pre-operative hypofractionated stereotactic radiosurgery followed by surgery will improve time to local failure (TTLF) compared to the current standard of care.
Meningioma are slow growing and frequently occurring intracranial tumors, responsible for 33% of all asymptomatic intracranial tumors and 13-26% of all symptomatic primary brain tumors. The 10-year survival rate is 72%. A variety of treatment options is available for symptomatic meningioma including surgical removal with or without radiotherapy or radiotherapy alone. These therapies can have negative impact on cerebral functioning. After high dose radiotherapy for primary or metastatic brain tumors 50-90% of > 6 months' survivors develop irreversible disabling cognitive decline leading to premature loss of independence, reduced...
The reference treatment of ocular melanoma is a conservative treatment by proton therapy. Its goal is to treat the tumor while preserving the eyeball and visual acuity. However, ablation of the eyeball is sometimes necessary after proton therapy in the case of neovascular glaucoma. This complication occurs in 7 to 47% of cases (depending on the size of the tumor) and is associated with hypersecretion of Vascular Endothelial Growth Factor (VEGF) related to necrotic and inflammatory tumor tissue after proton therapy or ischemic retina. The intravitreal injections of anti-VEGF are used in the treatment of neovascular radicular glaucoma...
The purpose of this study is to determine if performing radiotherapy (SRS) prior to surgery results in better treatment outcomes than performing surgery before radiotherapy for patients with brain metastases. Brain metastases occur when cancer cells from a primary cancer (e.g. lung, breast, colon) travel through the bloodstream and spread (metastasize) to the brain. As these new tumors grow they apply pressure and change how healthy brain tissue works. This can lead to a loss of brain function and worsening quality of life. Treatments for patients whose cancer has spread to the brain is often surgery, radiation therapy...
retrospective study focused on patients with a known diagnosis of PMLBCL which experienced a CNS relapse during the course of their disease to obtain information about the clinical characteristics, the management at diagnosis and at each relapses , and the outcome of these cases. The aim of the study is to put together the large International series on CNS+ PMLBCL data, coming from 6 different countries , on clinical factors, anti-lymphoma therapy administered alone or concomitant with CNS prophylaxis , the information about the site of re biopsy when available , the dose intensity of lymphoma therapy received at relapse and the ...
The goal of this clinical research study is to learn if pre-operative radiation therapy can help patients with sinonasal melanoma have better outcomes
Despite being standard of care, there are still many medical requirements related to immune checkpoint blocker based therapies such as identify patients susceptible to respond with the less adverse events, evaluate the clinical benefit of adjuvant treatment /risk of relapse and design new strategies for non-responder patients. Thus, this project aims at understanding the impact of anti-PD1 on the immune system through investigation of the phenotypic, functional, metabolic and transcriptomic profiles of circulating DC subsets and effectors in response to anti-PD1 therapy in melanoma patients. The primary objective of the study is...
