Active clinical trials for "Brain Neoplasms"

The aim of the study is to determine whether the use of the CEST sequence would have diagnostic performance equivalent to the reference method of T2* infusion with contrast injection in the diagnosis of radionecrosis of lung cancer brain metastases.

In the experimental group, norepinephrine at a concentration of 5 mcg/ml is preemptively administered through peripheral venous catheter with a size of 20 G or more from the time of anesthesia induction to the end of anesthetic administration. The norepinephrine is not preemptively administered in the control group. For anesthesia, total intravenous anesthesia using propofol and remifentanil is performed. During anesthesia, the injection rate of the test drug is allowed to be adjusted according to the blood pressure within the permissible range, and anesthesia management such as fluid infusion, blood transfusions, and drug administration is performed according to the judgment of the anesthesiologist, and there are no restrictions. The achievement of hemodynamic stability during anesthesia is judged by the percentage (%) of the time when the target blood pressure falls outside of 90-110%, 80-120%, and 70-130% of the target blood pressure during the total anesthesia duration. The number of hemodynamic unstability occurred, and the number of patients with hemodynamic unstability are also sought. The incidence of postoperative complications between the two groups is also compared.

Up to 10% of patients with cancer will develop symptomatic brain metastases. Given this limited survival it is important to consider quality of life (QOL) when treating these patients. Whole brain radiotherapy (WBRT) can increase survival to 6 month. However, WBRT itself has been shown to reduce QOL by increasing drowsiness, leg weakness and hair loss in patients with brain metastases. Both fatigue and hair loss were reported to have the largest decline in QOL scores when WBRT is used in the prophylactic setting in small cell lung cancer. Recent technological improvements in patient positioning and treatment planning will allow us to treat the whole brain with reduced margins, allowing better sparing of the scalp. In view of the large impact of hair loss on quality of life, the investigators hypothesize to see an improved quality of life with scalp sparing techniques. Study hypothesis: Volumetric arc therapy results in a reduced hair loss and a subsequent clinically important improvement in QOL.

Objective: To improve local control following complete resection of a single brain metastasis using fractionated local stereotactic radiotherapy, whilst maintaining neurological functioning, neurocognition and quality of life. Study design: Multicenter randomized phase III, with at least three high-volume Dutch centers participating in the trial. Stratification on primary tumor type and age. Study population: Patients undergoing complete resection of a single brain metastasis, confirmed by an early (i.e. within 72 hours) postoperative contrast-enhanced MR scan. Study intervention: Patients will be randomized between observation alone (standard arm) and local stereotactic radiotherapy in three fractions of 8 Gy to the surgical cavity (study arm). Main study parameters: Primary objective: local control rate at 6 months. Secondary objectives: local control rate at 12 months, neurological functioning, freedom from clinical neurological progression, performance status, quality of life, toxicity, steroid use, neurocognition and overall survival.

DC vaccine manufactured and partially matured using our standard operating procedures, developed in collaboration with the HGG Immuno Group, then administered through imiquimod treated skin will be safe and feasible in children with refractory brain tumors. This will result in anti-tumor immunity that will prolong survival of subjects treated and results will be consistent with the outcomes found for subjects treated by HGG Immuno Group investigators. Study treatment will correlate with laboratory evidence of immune activation. Correlative studies will also reveal targets in the immune system which can be exploited to improve response for patients on successor trials.

Brain metastases occur in 20% to 40% of all patients with cancer , with an incidence 10 times higher than that of primary malignant brain tumors. Patients with brain metastases have a poor prognosis with a median survival of 1-2 months with corticosteroids and 5-7 months with whole brain radiotherapy (WBRT). Local control achieved with WBRT in patients with otherwise controlled systemic disease remains at issue. A single high dose of radiation delivered with high precision to the target lesion (Stereotactic radiosurgery (SRS)), is considered standard care in salvage of recurrent lesions after WBRT. SRS can destroy tumour with very little damage to surrounding tissue. Research suggests that delivering radiotherapy in a number of smaller doses is more beneficial than receiving all of the radiotherapy in a single dose. Brain metastases are well suited for SRS as they are often small, radiographically well-circumscribed, pseudospherical tumors that are noninfiltrative.

A clinical study to investigate the maximum tolerated dose of Vandetanib and concurrent WBRT in patients with NSCLC and brain metastases. All patients will receive WBRT, 10 fractions of 3 Gy. Patients will start 7 days prior to start of radiation treatment with Vandetanib. Total treatment time with Vandetanib is 3 weeks (21 days). Patients will have the opportunity to continue Vandetanib until progression at a dose of 300 mg. This multi-centre study will be conducted in a minimum of 9 patients and a maximum of 18 patients at 3 sites.

This is a pilot imaging study in participants treated with stereotactic radiosurgery (SRS) to treat brain metastasis. The purpose of this study is to see whether 18F-Fluciclovine positron emission tomography (PET) can be used as a biomarker to measure response or progression of brain metastasis after SRS.

Aqueduct's Smart External Drain (SED) will be compared to the current gold standard for temporary CSF management in a hospital setting.

For patients with 1-6 intraparenchymal brain metastases from various primary histologies (except for melanoma), stereotactic radiosurgery (administered upfront or concurrently) or complete surgical resection with neural stem cell (NSC)-preserving whole-brain radiotherapy (WBRT) results in improved neurocognitive profile over standard WBRT. The goal of this study is to assess feasibility of this treatment approach.
