Rotating Frame Relaxation and Diffusion Weighted Imaging of Human Gliomas (RODIG)

June 13, 2018 updated by: Heikki Minn, Turku University Hospital

Grading of gliomas is of significant clinical importance since the prognosis as well as the treatment of choice are distinct in low-grade and high-grade gliomas. With standard MRI modalities, however, a reliable distinction is often impossible. Moreover, the gold standard for glioma grading by histopathology may also have limitations due to unrepresentative tumor samples. Therefore, more advanced MRI techniques are urgently needed that would have higher sensitivity and specificity in the definition of tumor type, grade and extent.

Assessment of radiologic response for high-grade gliomas utilizes the updated RANO criteria 12 weeks after completion of chemoradiotherapy. However, there is an urgent need to identify nonresponding patients earlier, preferentially midtreatment in order to consider alternative treatment strategies. Imaging biomarkers, such as diffusion weighted MR imaging (DWI), have provided promising results in assessing early treatment response. Furthermore, a serum biomarker with diagnostic value could improve tumor follow-up and clinical management of gliomas.

The aim of our study is to develop novel imaging protocols suitable for the magnetic resonance imaging (MRI) of glioma using advanced MRI techniques such as rotating frame imaging, novel DWI acquisition and post-processing methods We also study the correlation between advanced MRI parameters and histopathology of the tumor specimen. In addition, early treatment response is assessed with advanced MRI parameters at 3 week and 10 week after initiation of radiotherapy. Finally, our objective is to study the association between serum biomarkers and corresponding MRI with potential tumor progression.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with a brain tumor scheduled for a surgical resection at the Turku University Hospital, Finland.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rotating frame relaxation and diffusion weighted MR parameters in the tumor and surrounding area
Time Frame: Prior to surgical resection
Different MR relaxation parameters (T1rho-adiabatic,T1rho-cw T2rho-adiabatic,... ) and diffusion values (ADCm, ADCk, K, f, Df, Ds,...) will be measured in the tumor and surrounding area. The quantitative values will be correlated with cancer aggressiveness and tissue bio-markers. Furthermore, tumor volume will be estimated using different quantitative values.
Prior to surgical resection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in rotating frame relaxation and diffusion weighted MR parameters in the residual tumor during therapy
Time Frame: Before, after 3 weeks, and after 10 weeks of the beginning of radiotherapy, and 12 weeks after completion of radiotherapy
Change in the different MR relaxation parameters (T1rho-adaibatic,T1rho-cw T2rho-adiabatic,... ) and diffusion values (ADCm, ADCk, K, f, Df, Ds,...) during tumor therapy will be estimated from repeated MR examinations performed before, after 3 weeks, and after 10 weeks of the beginning of radiotherapy, and 12 weeks after completion of radiotherapy.
Before, after 3 weeks, and after 10 weeks of the beginning of radiotherapy, and 12 weeks after completion of radiotherapy
