Filter by:Parotid neoplasm consists of a wide range of benign and malignant lesions, and parotidectomy has been the mainstay for management of these neoplasms. Within the parotid gland there are branches of the intra-parotid facial nerves, which are tiny in calibre and are prone to injury to injury during operation. It has been reported in recent retrospective view that the incidence of temporary and permanent facial nerve injury were 9.2% and 5.2% respectively, the risk of which increased with old age, malignant tumour and revision surgery. Traditional the incidental of facial nerve injury is reduced by intra-operative facial nerve monitoring and surgical magnification, while imaging has limited role in aiding this purpose. However with advancement in MRI technique high resolution three-dimensional sequences (i.e. neurogram sequences) are available for better visualization of branches of facial nerves. The investigators would therefore aim to demonstrate additional efficacy of these techniques and also to compare with conventional 3D post-contrast anatomical imaging studies in the localization and visualization of the facial nerve branches in patients with tumour. With better pre-operative imaging, the investigators hope to reduce the chance of facial nerve injury in these patients.
This study aims to explore the recommended phase 2 dose and evaluate the safety, tolerability and preliminary antitumor activity of BGB-16673 monotherapy at the recommended Phase 2 dose for the selected B-cell malignancy expansion cohorts
Brain surgery operations include brain tumour removal and blood vessel procedures. Each year in the UK, approximately 70,500 patients are diagnosed with a brain tumour, 5,000 of whom undergo surgery. Approximately 1,000 patients undergo blood vessel brain surgery. Brain tumour surgery involves removing as much of the tumour as safely as possible. If all tumour is removed, patients have significantly better outcomes and live longer. However, even with the best hands and the most modern technology currently available, it is often not possible to reliably identify tumour during surgery. Moreover, nerves and blood vessels cannot be reliably identified either during surgery. Yet, they need to be preserved to avoid brain damage. Due to this uncertainty and the need to balance risks, tumour is often left behind. Today, close to 30% of brain tumour patients require repeat surgery owing to tumour left behind during their first surgery. Further surgeries are more difficult, pose additional patient risks and lead to increased healthcare costs with often poor patient outcomes. Newly developed camera systems have the potential to enhance the surgeon's vision to reliably identify tumour and healthy brain structures. Hyperspectral imaging (HSI) is one of the most promising of such technologies. Its core ability is to provide very detailed and rich information that is invisible to the human eye. HSI has demonstrated the potential to provide crucial, but currently unavailable, information about tumour and critical brain structures during surgery. However, HSI data is very complex and requires advanced computer-processing for its interpretation. In this project, we will use a HSI imaging system to record data in 81 patient undergoing brain including 63 patients with brain tumours and 18 patients suffering from brain vessel abnormalities. Using this data we will develop key computer-processing features to enable real-time image interpretation.
Polyplastic glioblastoma and metastatic brain cancer are the most common malignant brain tumors in adults. The primary diagnostic test for tumors in the brain shows magnetic resonance imaging or similar imaging findings (especially single metastatic brain cancer) that make it difficult to distinguish between these two diseases. In addition, due to the specificity of the tissue called the brain, biopsy is not easy and sometimes biopsy is difficult, so non-invasive discrimination is often important, and it is important how much prediction is made before the biopsy. To solve this problem, various advanced magnetic resonance imaging techniques have been studied, but they are all tests that need to be additionally conducted on ordinary magnetic resonance images, and there are many subjective factors, so complex data and statistical processing methods, and many cannot be easily tested. In addition, in all of these tests, accuracy is still reported at around 60%. Therefore, if contrast-enhanced FLAIR images can be obtained along with contrast-enhanced T1 images performed during conventional magnetic resonance imaging tests to help differentiate between two diseases, it will greatly help diagnose and treat brain tumor patients and facilitate clinical application.
This is a phase Ia/Ib, first-in-Human, open-Label, multicenter, dose escalation and dose expansion study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary efficacy of SG2501 in subjects with relapsed or refractory hematological malignancies and lymphoma.
Purpose : the aim of this study is to assess the feasibility and safety of ultrasound-induced opening of the blood-brain barrier (BBB) with the SonoCloud-9 implantable ultrasound device in pediatric patients treated for a recurrent malignant supra-tentorial brain tumor treated with carboplatin. Study hypothesis : the blood-brain barrier can be transiently and safely opened with pulsed low intensity ultrasound immediately prior to intravenously delivered chemotherapy. The opening of the BBB with the SonoCloud-9 system will increase the tumor exposure to carboplatin and increase progression-free and overall survival in pediatric patients treated for a recurrent malignant supra-tentorial brain tumor.
This is a phase 1, open-label, single-arm, first-in-human study to evaluate the safety, tolerability, pharmacokinetics (PK) and anti-tumor activity of SY-4835 administered orally in patients with advanced solid tumors.
This is a Phase 1, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, and DLTs to establish the maximum tolerated dose (MTD) or maximum administered dose (MAD), and the RP2D of sequential doses of IBI363 (study drug) in subjects with advanced, refractory solid malignancies or lymphomas.
The objective of this study was to explore whether the combination with umbilical cord blood (UCB) is associated with superior disease-free survival (DFS) in the setting of haploidentical donors (HID) transplantation.
The purpose of the CaboAveNEC trial is to investigate the clinical activity and safety of Cabozantinib in combination with avelumab in patients refractory to standard chemotherapy with advanced neuroendocrine neoplasias G3 (NEN G3).
