SeOuL cOhort of Brain Tumor MONitoring Study (SOLOMON)

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

 No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT05254197
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Non-malignant central nervous system (CNS) tumor accounts for 70% of all primary CNS tumors, and over 300,000 patients were diagnosed with non-malignant CNS tumor per year in the United States. Not much is known about the natural history of non-malignant CNS tumors, as it is often treated immediately upon detection. However, some of them, especially small and asymptomatic non-malignant CNS tumors should not be treated immediately upon diagnosis but are observed and followed-up by repeated magnetic resonance imaging (MRI). This study aims to make a prospective cohort of non-malignant CNS tumors that do not require immediate treatment and to quantitatively analyze which factors are related to the growth of tumors. 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 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. Non-malignant brain tumors are defined as radiologically diagnosed neoplasms of CNS WHO grade 2 or lower among primary intracranial tumors and include meningioma, schwannoma, pituitary adenoma, and glioma suspected to be non-malignant.

Arms & Interventions

Arms

: Retrospective cohort

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 1998, and who have had MR re-examination after first MR exam because it was determined that immediate treatment would not be needed at the first visit to the hospital. Non-malignant brain tumors are defined as radiologically diagnosed primary intracranial neoplasms of CNS WHO grade 2 or lower and include meningioma, schwannoma, pituitary adenoma, and glioma suspected to be non-malignant. It is practically impossible to obtain informed consent from patients of this retrospective cohort, and consent was waived by the Institutional Review Board. Target population of this retrospective cohort is 1,500 tumors.

: Prospective cohort

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 February 2022, and who have had 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. Non-malignant brain tumors are defined as radiologically diagnosed primary intracranial neoplasms of CNS WHO grade 2 or lower and include meningioma, schwannoma, pituitary adenoma, and glioma suspected to be non-malignant. The cohort will consists of patients who agree to participate with written consent. Target population of this prospective cohort is 1,500 tumors.
