Overview
This is a study evaluating the positron-emitting radiopharmaceutical 18F-mFBG compared to 123I-mIBG scintigraphy for imaging of neuroblastoma
Description
This is a prospective study designed to assess the use of 18F-mFBG PET imaging compared to 123I-mIBG scintigraphy in subjects with known or presumed neuroblastoma. Eligible participants will have either histopathologically established diagnosis of neuroblastoma or a presumed diagnosis based on signs, symptoms, physical examination, imaging findings, and laboratory and genetic test results.
Subjects will only be administered 18F-mFBG if they have undergone or are scheduled to undergo a 123I-mIBG within +/- 7 days of the date of the 18F-mFBG scan. Subjects should not have received any chemotherapy, immunotherapy or radiotherapy between the clinical and 18F-mFBG imaging studies.
18F-mFBG PET studies will be evaluated by 2 independent teams of blinded readers: a nuclear medicine physician and a radiologist, both specialized in pediatric nuclear medicine co-reading side-by side.
The clinical 123I-mIBG is also evaluated by 2 independent teams of blinded readers: a nuclear medicine physician and a radiologist, both specialized in pediatric nuclear medicine co-reading side-by side.
Blinded readers will record whether findings on 18F-mFBG and 123I-mIBG scans are consistent with neuroblastoma.
Subject-level diagnostic performance will be assessed on the basis of differencies in lesion-counting between the blinded 18F-mFBG scan interpretation and the 123I-mIBG scan. In case of discrepancy, independently assessed by an Expert Panel.
Eligibility
Inclusion Criteria:
- An established diagnosis of neuroblastoma based on unequivocal histopathology from tissue obtained at any time prior to enrolment in the trial; OR b) A presumed diagnosis of neuroblastoma based on signs, symptoms, physical examination, imaging findings, and laboratory and genetic test results, including individuals in whom therapy has already been empirically initiated.
- The subject has undergone or is scheduled to undergo evaluation of neuroblastoma disease status, including 123I-mIBG +/- 7 days to the date of 18F-mFBG imaging, with no therapy between such evaluation.
- Ability of subject or subject's legal guardian to understand and sign a written
informed consent document.
