Active clinical trials for "Brain Neoplasms"

This Phase II study is to determine the efficacy and safety of MR-Linac Guided Adaptive fractionated stereotactic radiotherapy (FSRT) in patients with brain metastases in non-small cell lung cancer.

Subject population：Patients with brain metastases from EGFR mutation-positive non-small cell lung cancer who have not received systemic treatment. Experimental design: Single-center, single-arm phase II clinical trial. Purpose: Efficacy and safety of Anlotinib combined with Almonertinib in the treatment of patients with brain metastases from EGFR mutation-positive non-small cell lung cancer. treatment plan: 1). Anlotinib: 12mg/time (BSA≥1.6 m2) or 10mg/time (BSA<1.6 m2), once a day orally, taking two weeks and stopping for one week; 2). Almonertinib: 110mg, orally once a day; primary endpoint: Intracranial progression-free survival (iPFS); secondary endpoint: Objective intracranial response rate (iORR=iCR+iPR), intracranial disease control rate (iDCR=iCR+iPR+i SD), overall progression-free survival (PFS), overall survival (OS), quality of life score.

In the preoperative waiting area, the patients are randomly assigned and divided into two groups according to the allocation sequence table (corresponding to 1:1 randomization) generated by the computer. The propofol group was both induced and maintained at an effect-site concentration (Ce) of 2.0-4.0 mcg/mL by a target-controlled infusion (TCI) system. The sevoflurane group was maintained via sevoflurane vaporizer between 1% and 3% (target minimum alveolar concentration of 0.7-1.3). The following patient data were recorded, the type of anesthesia, sex, age at the time of surgery, preoperative Karnofsky performance status (KPS) score and functional capacity, the postoperative complications within 30 days (according Clavien-Dindo classification), American Society of Anesthesiologists(ASA) physical status scores, tumor size, intraoperative blood loss/transfusion, duration of surgery, duration of anesthesia, total opioid (remifentanil/fentanyl/ propofol) use, postoperative radiation therapy, postoperative chemotherapy, postoperative concurrent chemoradiotherapy, the presence of disease progression, and 6-month, 1-year, and 3-year overall survival and Karnofsky performance status score were recorded.

Background: Distress, anxiety, and other psychological disorders may be more common in people with primary brain tumors (PBTs). PBTs can affect their symptoms, quality of life, and their tolerance of cancer treatments. Researchers want to learn if virtual reality (VR) technology can help reduce stress and improve mood. VR uses computer technology to make fake experiences and environments that look real. This allows people to escape from their lives and experience more positive thoughts and emotions. Objective: To learn if it is feasible to use a VR relaxation intervention in people with PBTs. Eligibility: Adults 18 and older who have a brain tumor and have recently reported psychological distress during their participation in the Natural History Study (NHS), protocol #16C0151 Design: The VR intervention and all patient-reported outcome measures (PROs) will be done remotely using telehealth. Participants will be mailed a VR headset. This headset looks like a thick pair of goggles that is worn over the eyes. Participants will view computer-generated environments on this VR headset. Participants will fill out symptoms questionnaires at 4 different times points during participation in this study, including questionnaires for the NHS as well as 4 questionnaires unique to this study. There are also optional saliva samples collected at these timepoints. The 4 timepoints are: Before the VR intervention After the VR intervention 1 week later 4 weeks later Participants will also have a phone interview 1 week after the initial VR interevention, which will last 10 to 15 minutes. Participation lasts 4 to 6 weeks.

This study aimed to evaluate the use of SHR-A1811 in HER2-expression Advanced Breast Cancer patients with brain metastases.

This study is designed to see if we can lower the chance of side effects from radiation in patients with breast, kidney, non-small cell lung cancer or melanoma that has spread to the brain and who are also being treated with immunotherapy, specifically immune checkpoint inhibitor (ICI) therapy. This study will compare the usual care treatment of single fraction stereotactic radiosurgery (SSRS) given on one day versus fractionated stereotactic radiosurgery (FSRS), which is a lower dose of radiation given over a few days to determine if FSRS is better or worse at reducing side effects than usual care treatment.

To learn if giving nivolumab in combination with relatlimab can help to control melanoma that has spread to the brain (melanoma with brain metastases). The safety and side effects of the study drug combination will also be studied.

This study was a single-arm, open-label, phase II study of breast cancer patients with brain metastases. Eligible patients received a regimen of eutidrone(30mg/m2/d,iv,d1-5,21d/cycle), etoposide(30mg/m2/d,iv,d1-3,21d/cycle), and bevacizumab (10mg/kg,d1,21d/cycle).At least 4 to 6 cycles were administered, and if patients had a response or stable disease, bevacizumab was used as maintenance therapy until disease progression or intolerable toxicity.

The occurrence of brain metastases (BMs) is increasing given the availability of a more accurate radiological imaging such as MRI for detecting also small brain lesions and the most effective systemic therapy able to control extracranial disease. Although, the new target therapy and immunotherapy has proven to be effective on brain metastasis too, a subgroup of patients shows prove themselves unresponsive to medical treatment. A further subgroup of patients exhibit diffuse brain disease for the presence of multiple brain lesion (>10 BMs) or leptomeningeal carcinomatosis. Among these patients the most treatment employed is represented by whole brain RT. Since the 1950s, whole-brain radiation therapy (WBRT) has been the most widely used treatment for patients with multiple brain metastases, given its effectiveness in palliation, widespread availability, and ease to delivery. However, the median overall survival recorded is restricted to 3 months, on the average. A better understanding of the molecular and cellular mechanisms underlying brain metastasis might be expected to lead to improvements in the overall survival rate for these patients. Recent studies have revealed complex interactions between metastatic cancer cells and their microenvironment in the brain. Priego et al. describe that brain metastatic cells induce and maintain the co-option of a pro-metastatic program driven by signal transducer and activator of transcription 3 (STAT3) in a subpopulation of reactive astrocytes surrounding metastatic lesions. In patients, active STAT3 in reactive astrocytes correlates with reduced survival from diagnosis of intracranial metastases. Blocking STAT3 signaling in reactive astrocytes reduces experimental brain metastasis from different primary tumor sources, even at advanced stages of colonization. Silibinin (or silybin) is a natural polyphenolic flavonoid isolated from seed extracts of the herb milk thistle (Silybum marianum). Silibinin has been shown to impair STAT3 activation. Preclinical studies show that Silibinin has an anticancer effects in vitro and in vivo. Based on this background, the investigators designed a double arm randomized trial evaluating the benefit of Silibinin (in the form of marketed supplement) associated to WBRT respect to WBRT alone.

The survival interval of patients with gliomas ranges between 12 to 15 months. Recent findings revealed that dietary interventions to reduce glucose and glycolytic pathways could have a therapeutic effect. Ketosis can be an effective therapy to extend the survival of patients with gliomas.
