NCT ID: NCT06421805 Recruiting - Lymphoma Clinical Trials

Establishing Prospective Mediastinal Tumor Database of PUMCH

MTDPUMCH
Start date: January 1, 2012
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05576103 Recruiting - Glioma Clinical Trials

Longitudinal Prospective Study of Neurocognition & Neuroimaging in Primary BT Patients

Start date: January 2015
Phase:
Study type: Observational

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.

NCT ID: NCT05254197 Recruiting - Meningioma Clinical Trials

SeOuL cOhort of Brain Tumor MONitoring Study (SOLOMON)

SOLOMON
Start date: January 1, 2001
Phase:
Study type: Observational [Patient Registry]

The registry of this study was subjected to patients who were radiologically diagnosed with a non-malignant brain tumor at Seoul National University Hospital since 2001, and who have had magnetic resonance (MR) re-examination after first MR exam or will be re-examined because it was determined that immediate treatment would not be needed at the first visit to the hospital. In all MRs taken by patients, the date of imaging and the volume of the tumor are measured, and we aim to establish a natural growth history for non-malignant brain tumors.

NCT ID: NCT05139277 Recruiting - Glioblastoma Clinical Trials

Evaluation of the CONVIVO System

Start date: June 28, 2022
Phase: N/A
Study type: Interventional

The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation.

NCT ID: NCT04712214 Recruiting - Glioma Clinical Trials

Use of Non-invasive Optical Analysis in Neurosurgery

Start date: March 28, 2021
Phase: N/A
Study type: Interventional

The present study aims to investigate the potential application of multispectral analysis, hyperspectral imaging, and fluorescence during neuro-oncological procedures, specifically during brain tumour debulking / resection. These optics techniques are entirely non-invasive and consist in camera with a filter to be linked to the standard microsurgical and endoscopic instruments used in theatre. The research procedure consists of images acquisition and data processing, with virtually no additional invasive procedures to be performed on patients.

NCT ID: NCT04417868 Recruiting - Schwannoma Clinical Trials

Evolution of Cochleovestibular Schwannomas

Start date: January 1, 2019
Phase:
Study type: Observational

Investigators want to know the natural history of the vestibular schwannomas: increasing, decreasing or stability, by monitoring more than 3 MRIs during a span of more than 2 years. They will obtain 3 groups: the volume increasing schwannomas which will be the most important group, the schwannomas that will be stable and a small group where the schwannomas will decrease. The secondary purpose is that the investigators want to know the threshold values: a minimum volume under which we are sure that the schwannoma will not increase, a maximum value where it will increase and if its evolution can be correlated to clinical or radiological criteria.

NCT ID: NCT04278118 Recruiting - Clinical trials for Intracranial Neoplasm

Hypofractionated Proton Therapy for Benign Intracranial Brain Tumors, the HiPPI Study

HiPPI
Start date: February 18, 2020
Phase: N/A
Study type: Interventional

This phase II trial studies how well hypofractionated proton or photon radiation therapy works in treating patients with brain tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells. A shorter duration of radiation treatment may avoid some of the delayed side effects of radiation while providing a more convenient treatment and reducing costs.

NCT ID: NCT03580850 Recruiting - Schwannoma Clinical Trials

MRI Scan and Intra-labyrinthine Schwannoma

Start date: February 2, 2018
Phase:
Study type: Observational

Evaluate the interest of gadolinium for the positive and topographic diagnosis of intra-labyrinthine schwannoma, comparing T1 sequence acquired after gadolinium injection to a sequence of fast imaging type employing steady state acquisition (FIESTA-C)

NCT ID: NCT01951365 Completed - Schwannoma Clinical Trials

Assessment of Volumetric Growth Rates of Spinal Intradural Extramedullary Schwannoma

Start date: June 1998
Phase: N/A
Study type: Observational

Spinal intradural schwannoma detected incidentally increased recently. Because there is little knowledge about natural history of spinal schwannoma, there is no consensus of treatment. Our hypothesis is as follows; 1. Some schwannomas keep growing, the others do not. 2. Foraminal schwannomas do not usually grow. The investigators analyzed natural history and characteristics of 56 spinal schwannomas observed initially with accurate and reliable methods. Here the investigators displayed growing pattern and differential point of spinal schwannoma.

NCT ID: NCT01347307 Completed - Meningioma Clinical Trials

Stereotactic Body Radiotherapy for Spine Tumors

Start date: September 2008
Phase: N/A
Study type: Interventional

This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of spine metastases and benign spine tumors.
