Advanced Diffusion MRI to Differentiate Tumor Recurrence From Pseudoprogression in Patients With Glioblastoma and Brain Metastases

Study Purpose

This pilot study investigates whether advanced diffusion-weighted MRI (ADW-MRI) can differentiate between true tumor progression (TP) and a pseudoprogression (PsP) in patients with glioblastoma (GBM) or brain metastases.

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.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients with histopathologically proven glioblastoma or brain metastasis and suspected tumor progress on standard MRI after first line therapy and who are candidates for elective surgical resection.

- Able to give informed consent.

Exclusion Criteria:

- Contraindications to MRI (e.g. claustrophobia, pacemaker or other implants without MRI-approval, pregnancy) - Patients in a life-threatening condition.

- Patients in need of emergent surgery.

- Histopathological analyses of insufficient quality.

- Unable to give informed consent.

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.	NCT05911230
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.	N/A

Additional Details

Advanced diffusion-weighted MRI (ADW-MRI) offer the opportunity of higher sensitivity towards subtle tissue changes associated with increased specificity relating to damage of different tissue components of the central nervous system (CNS). Within the framework of this study, conventional follow up MRI will be complemented by ADW-MRI in case of suspected tumor recurrence and possible surgical resection of the suspicious tissue. In the case of surgical resection, the histopathological findings will be correlated to the findings of the ADW-MRI. In the depicted pilot phase, the feasibility of the described protocol will be examined and the data concerning correlations between standard histopathologic and genetic workup of the resected tissue and the results concerning tissue features from ADW-MRI will be analyzed.

Arms & Interventions

Arms

Other: ADW-MRI imaging

Patients with a histopathologically proven glioblastoma or brain metastasis who have suspected tumor progression on standard MRI after standard first line therapy and who are candidates for surgical resection and undergoing the ADW-MRI preoperatively.

Interventions

Diagnostic Test: - Advanced diffusion-weighted MRI (ADW-MRI)

An advanced diffusion weighted MRI-sequence will be performed in addition to the routine MRI-diagnostics. This will require the patient to be scanned for additional 30 minutes in a separate MRI-scanner. This technique offers the opportunity of higher sensitivity towards subtle tissue changes associated with increased specificity relating to damage of different tissue components of the CNS. In the case of surgical resection, the histopathological findings will be correlated to the findings of the ADW-MRI.
