Filter by:This study aims to prospectively document the population characteristics, imaging findings, pathological features, prognostic factors, etc., of patients with mediastinal tumors. Clinical information will be structured and processed, and it is recommended to establish a mediastinal tumors database at Peking Union Medical College Hospital. The goal is to provide support for the quality of diagnosis and treatment, clinical protocols, and medical decision-making related to mediastinal tumors.
Schwannomas are mainly benign tumors, which develop mainly in the skull or in the cervical region. Retroperitoneal location is rare, since it represents between 0.5 and 5% of scwhanomas. The malignant retroperitoneal form is, however, more common than in other locations. Retroperitoneal schwannoma is often discovered during the exploration of unexplained lumbo-pelvic pain, or in the face of compression of nearby organs. Abdominopelvic CT and magnetic resonance imaging are essential to characterize the mass and verify its extension. The precise diagnosis is based on the pathological examination of the part, and complete surgical excision is the standard treatment. Acquiring the surgical techniques and skills necessary to carry out these types of procedures is essential to providing optimal patient care.
In standard of care regularly planned surgery, tissue will be obtained from patients who are suspicious for having vestibular Schwannoma (on MRI). The tissue that remains after the pathologist gathered sufficient for analysis, the remaining tissue is used for creating tumour stem cell organoids.
The study is a pilot efficacy study. The investigators aim to estimate mean baseline and post-treatment balance scores among Vestibular Schwannomas (VS) patients undergoing pretreatment rehab (PREHAB) or no PREHAB when managed with either surgery or radiosurgery.
Postoperative nerve palsy is a major complication following resection of neck peripheral nerve sheath tumors. This study is a retrospective cohort aimed to predict the nerve origin of neck peripheral nerve sheath tumors. Accurate preoperative identification of the nerve origin can improve surgical outcomes and patient counseling
This is a placebo-controlled, multi-arm phase II platform screening trial designed to test the safety, pain responses, and pharmacodynamic activity of multiple experimental therapies simultaneously in participants with moderate-to-severe pain due to schwannomatosis (SWN). This Master Study is being conducted as a platform that may allow participants with pain associated with schwannomatosis to receive a novel intervention throughout this study. Embedded within the Master Study are individual drug sub-studies: - Investigational Drug Sub-Study A: Siltuximab - Investigation Drug Sub-Study B: Erenumab-Aooe
The investigators aim to study the impact of stereotactic radiosurgery, for the treatment of vestibular Schwannoma, on the cochlear, vestibular, gustatory, and facial nerve functions and compare it with a conservatively treated group. The predictive value of radiological tumor characteristics on hearing preservation and vestibular function will be also evaluated. Additionally, the investigators will invite patients with vestibular Schwannoma to fill out questionnaires to assess their quality of life.
The investigators have developed a self-administered rehabilitation tool that incrementally guides the user to increase head motion to mitigate motion sickness and enhance postural recovery following centrifugation or unilateral vestibular nerve deafferentation surgery.
Resection of the vestibular schwannoma leads to acute peripheral or combined vestibular loss caused by a surgical lesion to the branches of the vestibular nerve and, less frequently also the lesion of the cerebellum. The lesion presents in patients with postural instability, vertigo, oscillopsia, and vegetative symptoms that may accompany it. The organism reacts to this state with the process of central compensation with the significant role of the cerebellum. The goal of the rehabilitation is to support this process and thus to make recovery faster and more efficient since not all patients are capable of complete restoration of the vestibular function. Up to date, rehabilitation includes, apart from the specific vestibular exercise, also the possibility of modern techniques using virtual reality space and prehabituation. Thanks to prehabituation, i.e., chemical labyrinthectomy with intratympanically installed gentamicin, the timing of the origin of the acute vestibular loss and the surgical procedure is separated. Therefore, there is a chance of achieving vestibular compensation before vestibular schwannoma removal. In the last decade, due to the advances in technology in the field of computer games and the applications for smartphones, the tools for virtual reality have become less expensive and more available in common praxis. Virtual reality is a technique for generating an environment that can strengthen three-dimensional optokinetic stimulation, subsequently the process of central compensation. Overall, it may shorten the time of recovery after the surgery and improve patients' quality of life.
In this proposal, the investigators introduce a novel, translational study to prospectively examine primary brain tumor patients undergoing fractionated radiation therapy to the brain. Quantitative neuroimaging, radiation dose information, and directed neurocognitive testing will be acquired through this study to improve understanding of cognitive changes associated with radiation dosage to non-targeted tissue, and will provide the basis for evidence-based cognitive- sparing brain radiotherapy.
