Clinical Trial Summary

Background: The assessment of extent of disease (staging) and response to therapy (restaging) is performed with computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET scan) or integrated FDG-PET/CT. Whole-body MRI with diffusion weighted imaging (WB-MRI with DWIBS) is a radiation-free method which allows imaging of the body with excellent soft tissue contrast in a single examination and could be an attractive alternative to FDG-PET and CT for the staging and restaging of malignant lymphomas in children. Aim of the study: The aims of this study are to compare the diagnostic performance of whole-body MRI (including DWIBS) to FDG-PET/CT and/or CT for the initial staging, early response assessment and restaging after completion of therapy in children with Hodgkin's lymphoma. Study design: Patients eligible for enrollment in this multicenter, prospective, diagnostic cohort study are children aged 8-18 years, with histologically confirmed Hodgkin's lymphoma, who are treated according to the EuroNet-PHL-C1 protocol (or trial with similar imaging strategy) in one of the participating centers. Patients will undergo WB-MRI in addition to the protocolar imaging routinely done (FDG-PET(/CT) and CT scan) at 3 time-points: at initial staging, after 2 chemotherapy cycles and at end of treatment. The investigators expect to enrol 75 patients in a 3 year study period. Staging and restaging results of WB-MRI (according to the Ann Arbor and Cheson classification, respectively) will be compared to those of FDG-PET(/CT) and CT. Clinical and radiological follow-up after 6 months will be used to solve any disagreements between FDG-PET, CT and WB-MRI. Additionally, the investigators will collect 3 year follow-up clinical data and data on follow-up imaging from the hospital charts of the patients, to better assess the prognostic value of FDG-PET and WB-MRI.


Description:

Background: The malignant lymphomas, Hodgkin´s lymphoma (HL) and non-Hodgkin´s lymphoma (NHL), comprise approximately 10% of childhood cancers. The assessment of extent of disease (staging) and response to therapy (restaging) is performed with computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET scan) or integrated FDG-PET/CT. Staging and restaging are important for choice of treatment and for determining prognosis. Unfortunately, FDG-PET and CT are accompanied by a significant amount of radiation exposure which may induce second cancers. New magnetic resonance imaging (MRI) techniques offer an alternative way for staging and follow-up of cancers. Whole-body MRI with diffusion weighted imaging (WB-MRI with DWIBS) is a radiation-free method which allows imaging of the body with excellent soft tissue contrast in a single examination and could be an attractive alternative to FDG-PET and CT for the staging and restaging of malignant lymphomas in children. Aim of the study: The aims of this study are to compare the diagnostic performance of whole-body MRI (including DWIBS) to FDG-PET/CT and/or CT for the initial staging, early response assessment and restaging after completion of therapy in children with Hodgkin's lymphoma. Study design: Patients eligible for enrollment in this multicenter, prospective, diagnostic cohort study are children aged 8-18 years, with histologically confirmed Hodgkin's lymphoma, who are treated according to the SKION / EuroNet-PHL-C1 protocol (or trial with similar imaging strategy) in one of the participating centers. Patients will undergo WB-MRI in addition to the protocolar imaging routinely done (FDG-PET(/CT) and CT scan) at 3 time-points: at initial staging, after 2 chemotherapy cycles and at end of treatment. We expect to enrol 75 patients in a 3 year study period. Staging and restaging results of WB-MRI (according to the Ann Arbor and Cheson classification, respectively) will be compared to those of FDG-PET(/CT) and CT. All imaging modalities will be assessed by a radiologist and nuclear medicine physician in a blinded fashion, using standardized score forms. Findings of FDG-PET and CT together will serve as the reference standard. Clinical and radiological follow-up after 6 months will be used to solve any disagreements between FDG-PET, CT and WB-MRI. Additionally, at least 3 year follow-up clinical data and data on follow-up imaging will be collected from the hospital charts of the patients, to better assess the prognostic value of FDG-PET and WB-MRI. Clinical/scientific relevance: This study aims to assess the accuracy of WB-MRI compared to FDG-PET(/CT) and CT in staging and response assessment of Hodgkin lymphoma. The results of this study can contribute to the development of evidence based 'radiation reduced' imaging protocols in Hodgkin's lymphoma.

Outcome

Type Measure Description Time frame Safety issue
Primary Staging (Ann Arbor) The primary outcome parameter will be the clinical stage according to WB-MRI (including DWIBS) and according to FDG-PET/CT. This clinical stage will be determined according to the Ann Arbor classification system for initial staging. Day 1
Primary Early treatment response assessment (Cheson criteria) The primary outcome parameter will be the clinical stage according to WB-MRI (including DWIBS) and according to FDG-PET/CT. This clinical stage will be determined according to the Cheson criteria for early response assessment. 2 months
Primary Restaging at end of therapy (Cheson criteria) The primary outcome parameter will be the clinical stage according to WB-MRI (including DWIBS) and according to FDG-PET/CT. This clinical stage will be determined according to the Cheson criteria for restaging. 6 months
Primary Follow up for 3 years after end of treatment The percentage of relapse of Hodgkin lymphoma in this study cohort will be assessed by a 3-year follow-up of clinical and imaging data, and the percentage of true- versus false-positives on WB-MRI at end of treatment compared to PET/CT using this follow-up. 3 years
Secondary Image quality The secondary outcome will be a (subjective) assessment of image quality and presence of artefacts, for both T1-weighted and T2-weighted MR images, MR-DWI as well as PET/CT. Day 1, 2 months, 6 months
Secondary Interobserver variability of WB-MRI for staging, early response assessment and restaging at end of therapy The interobserver variability of WB-MRI (including DWIBS) for staging, early response assessment and restaging at end of therapy will be determined for two observers. Day 1, 2 months, 6 months
