Active clinical trials for "Meningioma"

Several studies showed that radiotherapy as brain tumors treatment may affect cognition. It was observed that durable memory impairments could arise at irradiated patients if radiotherapy is applied on medial temporal lobes. However, results concerned studies of anterograde memory and none, this day, estimates the impact of radiotherapy on autobiographical memory which also involves hippocampus. The aim of this study is to evaluate effects of cavernous sinus or sellar region irradiation on autobiographical memory. Thirty 35 to 65 years old patients, with cavernous sinus meningioma or pituitary adenoma for who radiotherapy is indicated will be recruited.

RATIONALE: Pioglitazone hydrochloride may be effective treatment for cognitive dysfunction caused by radiation therapy. PURPOSE: This phase I trial is studying the side effects and best dose of pioglitazone hydrochloride in preventing radiation-induced cognitive dysfunction in treating patients with brain tumors.

Bevacizumab may reduce CNS side effects caused by radiation therapy. This randomized phase II trial is studying how well bevacizumab works in reducing CNS side effects in patients who have undergone radiation therapy to the brain for primary brain tumor, meningioma, or head and neck cancer.

Patients undergoing meningeoma resection surgery will be randomly assigned to two groups. One group will receive scalp nerve blocks with 0.5% ropivacaine, whereas the other group will receive scalp nerve blocks with 0.9% saline after anesthesia induction and before skull-pin insertion. Serum levels of TNF-α、IL-6 and IL-1β will be measured and compared at before surgery, 1h, 24h and 72h after surgery, respectively. VAS score, dosage of pain-control medicine and NRS score at the first three days after surgery, ratio of intracranial infection within 30d after surgery, and total hospitalization days and medical expenditure will also be recorded and compared between the two groups.

Aggressive growing meningiomas resistant to multiple surgeries and radiotherapy constitute an unmet pharmaceutical need in neurooncology, leading to a fatal issue within a few months. Grade II-III meningiomas progression-free survival (PFS) 6 is at 10-15%. Median PFS grade III meningioma is approximate 3 years. Alpelisib is a well-tolerated Phosphoinositide 3-kinase α (Pi3Kα) specific inhibitor. However, phosphatidylinositol-3-kinase (PI3K) and the mammalian target of rapamycin (mTOR) inhibition does not induce apoptosis in vitro and induces an antiproliferative effect without any radiologic response in most treated patients. Trametinib, a mekinist (MEK) inhibitor is currently used in combined treatment for recurrent melanomas in clinical practice with a good clinical tolerance at 1-2 mg daily. In vitro, on meningioma primary cell culture, Trametinib induces cell apoptosis via caspase activity. These results strongly suggest the relevance to combine Alpelisib and Trametinib in aggressive and recurrent meningiomas. Alpelisib and Trametinib combination has not been studied to date, despite each drugs have been separately studied in phase 3. Multicenter, open label, dose-finding phase I study of Alpelisib in combination with Trametinib administered at a fixed dose (1.5 mg daily), both drugs will be administered daily. Starting dose of Alpelisib will be 160mg/day and will be increased to 200mg/day or decreased to 120mg/day depending of grade 3-4 adverse events occurrence, to determine maximal tolerated dose (MTD) and recommended dose. Primary Objective is to determine the safety profile and tolerability of Alpelisib and Trametinib given in combination in patients with aggressive and refractory meningiomas in terms of Dose-Limiting Toxicities (DLT, assessed during cycle 1).

The aim of the current study is to evaluate, in a prospective cross-over, randomized study, the effect of hyperbaric oxygen therapy (HBOT) on patients with chronic neurological deficits and cognitive impairment after anterior skull base meningioma tumor removal.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving high-dose radiation therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying radiation therapy to see how well it works in treating patients who have undergone surgery for newly diagnosed grade II or grade III meningioma.

Traditional treatment options for optic nerve sheath meningiomas (ONSM) include observation, surgery and radiotherapy, but to date none of these has become the clear treatment of choice. The role of the radiotherapy remained uncertain because of the concern about radiation related optic neuropathy In the recent past two large series of patients treated with a fractionated stereotactic radiotherapy confirmed these positive experiences in tumour control and greatly reduced the concern about the treatment related toxicity. Under the light of successful meningiomas treatment, radiosurgery, had proposed as a treatment option. Single session, high conformality, frame based radiosurgery systems are seldom if ever proposed as ONSMs treatment due to the known dose tolerance of the optic nerve. The first experience in ONSMs treatment with multisession radiosurgery treatment was quite promising. The aim of the present study is to prospectively evaluate the efficacy and safety of multisession radiosurgery in ONSMs treatment. In order to evaluate multisession radiosurgery 50 patients will be enrolled in the present study. All patients will be treated by using multisession radiosurgery, with 5 fractions of 5 Gy each to a total dose of 25 Gy prescribed to the 75-85% isodose line. Patients were evaluated both for tumor growth control and visual function.

The purpose of this study is to determine whether Tranexamic Acid is effective or not in the reduction of intraoperative bleeding loss in brain tumors resections.
