Gliomas are the most common type of primary brain tumors, with surgery followed by radiotherapy and chemotherapy as the main treatment modalities. However, they are highly prone to recurrence, presenting significant treatment challenges, especially for high-grade gliomas, which have a 5-year survival rate of only 5.5%. Paclitaxel, a common chemotherapeutic agent, exhibits antitumor effects in vitro that are 1400 times stronger than those of temozolomide (the first-line chemotherapy drug for gliomas). However, due to its large molecular weight (approximately 893 Da), it cannot cross the blood-brain barrier, precluding its use as a...
The efficacy of treatment with metformin for promoting cognitive recovery and brain growth in children/adolescents treated for medulloblastoma will be investigated in a multi-site Phase III randomized double-blind placebo-controlled parallel arm superiority trial. Specifically, in children/adolescents aged 7 years to 17 years and 11 months who have completed treatment for medulloblastoma, is oral administration of metformin for 16 weeks associated with greater improvement of cognitive function and brain growth compared to placebo administered for 16 weeks?
Patients with Supratentorial tumor undergoing craniotomy have a higher risk of postoperative pain, which will affect their postoperative quality of recovery (QoR). Although scalp nerve block (SNB) can alleviate postoperative pain, the effect on postoperative QoR in patients with supratentorial tumor undergoing craniotomy is still unclear. This study is aimed to explore the effect of SNB on postoperative QoR in this population. To explore the effect, we design a randomized controlled trial in which 84 patients with supratentorial tumor will be randomly assigned to either the SNB group or control group. The primary outcome is 15-item ...
Glioblastoma (GBM) is a highly malignant, incurable primary brain tumor. Due to the nature of this disease and the extent of the treatment (surgery followed by chemoradiation according to the Stupp trial) patients undergo considerable psychological distress. It is known that stress hormones are involved in a wide range of processes involved in cell survival, cell cycle and immune function, and can cause therapy resistance. In this study the effect of stress on outcome after chemoradiation in patients with GBM will be investigated.
Background: Cushing s disease is caused by excess ACTH hormone release by a benign tumor of the pituitary gland. It can lead to decreased quality of life and early death. The current best treatment for Cushing s disease is surgery. If surgery does not work or if the tumor returns, there are no more good treatment options. Vorinostat, which is approved to treat a type of lymphoma, might be a treatment option. Objective: To test vorinostat to see if it can kill tumor cells and change the number of hormones released in people with Cushing s disease. Eligibility: People ages 18 and older who have Cushing s...
This study is designed to investigate the effects of ketogenic milieu induced by acute exercise as well as the effects of recurrent exercise bouts on functional status and the accumulation in peripheral blood of MDSCs and the consequent balance on antitumor immunity in melanoma patients.
Study is enrolling newly diagnosed breast cancer patients about to start chemotherapy and age-matched control participants. The investigator is trying to better understand the prevalence of cognitive difficulties in cancer patients receiving chemotherapy compared to the general population as well as what biological mechanisms may play a role in the development of these difficulties. Patients will be asked to complete six assessments over the course of approximately 5 months. Assessments 1,3, 4.5 and 5 include computerized and paper and pencil cognitive testing as well as blood draws. Assessments 2 and 4 only involve the collection of...
Intraoperative flash visual evoked potentials (FVEPs) could monitor visual function during neurosurgery. There are fewer reports comparing the effects of sevoflurane-propofol balanced anesthesia and propofol-based total intravenous anesthesia under comparable bispectral index (BIS) levels on the amplitude and latency of flash visual evoked potentials (FVEPs) for sellar or parasellar tumors resection neurosurgeries.
The growth of gliomas often infiltrates important brain tissues and impairs subcortical fiber transmission, resulting in changes in global brain network connectivity. Most of the current anesthesia depth monitoring methods are based on healthy brain function population,which is difficult to reflect the sedation depth of glioma patients accurately. Therefore, this study aims to explore the characteristics of brain network connectivity in glioma patients under different sedation depths by electroencephalogram (EEG) and auditory event-related potential (AERP) methods, which may provide a research basis for sedative titration and anesthesia ...
To explore whether the patients with prostate cancer have functional changes in specific brain areas and changes in psychological and mental characteristics compared with the patients without prostate cancer.
