The study of investigators indicated that TMZ can up-regulate dopamine D2 receptor (DRD2) expression, and mediates Ferroptosis inhibition and chemoresistance of GBM. The clinical data also proved that the DRD2 expression in recurrent GBM is significantly higher than that in primary GBM. Moreover, the DRD2 antagonist haloperidol can attenuate the above function of DRD2, and increase the sensitivity of GBM to the TMZ by inducing fatal autophagy and ferroptosis. In xenograft mice, the combined usage of haloperidol and Temozolomide (TMZ) can significantly inhibit tumor growth and increase overall survival. The investigators' findings have been published in Clinical cancer research....
This trial is a single arm study for patients receiving bevacizumab for IDH-wildtype glioblastoma. Patients receiving bevacizumab (an anti-VEGF therapy) will receive PSMA scans to investigate the role of PSMA expression in glioblastoma and its relationship to VEGF expression.
The goal of this clinical trial is to learn about in patients with supratentorial brain tumours. The main questions it aims to answer is: Can short-term preoperative walking exercise protect cognitive function in the short term after craniotomy in patients with supratentorial brain tumor and reduce the incidence of surgery-related complications? Participants will be asked to receive general care and regular walking exercises prior to surgery. Researchers will compare patients who receive only general care before surgery to see if preoperative walking exercise has an effect on postoperative prognosis.
The pineal region and brainstem tumors are located at the central position of the cranial cavity, surrounded by important neural structures and venous systems, leading to challenges in preoperative diagnosis, adding uncertainty and complexity to treatment. For a long time, surgical treatment of pineal region and brainstem tumors has been one of the most challenging areas in neurosurgery. With the development of neuroendoscopy and virtual endoscopy technologies, how to convert complex three-dimensional bone, vascular, and neural images into virtual endoscopic images and how to combine virtual endoscopy with neuro-navigation for endoscopic skull base surgery to provide...
Medical treatments have improved survival rates for children with brain tumours. However, most children experience long-term difficulties with 'cognition' (thinking skills such as memory and paying attention) and cognitive fatigue (excessive mental tiredness) after treatment. Thinking difficulties and fatigue can affect a child's ability to learn, and their social and emotional wellbeing. National guidance recommends treatment called 'cognitive rehabilitation' which teaches skills to improve or manage cognitive difficulties. Families often request this, but it is not usually available due to little research. Fatigue may also get in the way of children using and benefiting from...
The goal of this clinical trial is to adapt, implement, and evaluate MyCarePulse and ASCENT patient navigator to overcome barriers to care among patients with cancer. The main hypotheses it aims to test are: - At the patient level, the intervention will result in higher levels of food security, self- efficacy for dietary behaviors, and higher diet quality than standard care. - At the provider level, the intervention will be feasible, acceptable, appropriate, and able to enhance individualized care for patient wellness. Researchers will compare cancer patients receiving the MyCarePulse and ASCENT patient navigator intervention to those receiving...
The goal of this clinical trial is to demonstrate that simulation training for paramedical staff in neurosurgery departments, in announcing and accompanying patients with a brain tumor, improves patient satisfaction when a (potentially malignant) brain tumor is discovered, compared with usual care. The main question it aims to answer is: - Are patients more satisfied (as measured by scores on the EORCT IN-PATSAT32 questionnaire) with their neurosurgical hospitalization following the discovery of a brain tumor in centers where paramedics have been trained by simulation? Researchers will compare the results of the EORTC IN-PATSAT32 questionnaire to determine whether paramedic...
The goal of this study is to investigate the incidence and risk factors of central nervous system adverse events of Lorlatinib in patients with ALK-positive advanced non-small cell lung cancer.
The goal of this clinical trial is to demonstrate that there is no difference (non-inferiorty) in the 2 year recurrence-free survival (RFS) between 2 different surgical approaches for clinical Stage III melanoma. Following 6 weeks of standard neaodjuvant immunotherapy, patients will undergo either selective index lymph node resection (ILN) (identified at baseline as the largest affected lymph node) or the standard of care therapeutic lymph node dissection (TLND). The secondary aims are to assess if patients who are managed without TLND will have a reduction in surgical complications (less wound problems & lymphoedema), an improved quality of life, at a lower healthcare utilisation.
The goal of this observational study is to learn about the diagnostic value of preoperative MRI examination for adult-type diffuse gliomas. The main question it aims to answer is: - Can preoperative MRI examination noninvasively predict genotype of gliomas? - Can preoperative MRI examination noninvasively predict the overall survival of gliomas? - Can preoperative MRI examination noninvasively predict Ki-67 proliferation status?
