Summary

Rationale: Hereditary retinoblastoma survivors have an increased risk to develop second primary tumors (SPT) at a later age (with the highest risk in their teens), especially when they have been irradiated for retinoblastoma. The investigators hypothesize that regular screening with magnetic resonance imaging (MRI) could lead to early detection of SPTs leading to improved survival.

Objective: To evaluate the potential benefit of craniofacial MRI screening for early detection subclinical secondary cancers in patients previously irradiated for hereditary retinoblastoma.

Study design: Prospective multicenter non-invasive screening study. The total study duration will be four years of screening plus five years of follow-up.

Study population: Irradiated hereditary retinoblastoma patients 8-18 years old Main study parameters/endpoints: To evaluate the ability of craniofacial MRI for early detection of SPTs, the investigators will determine the sensitivity and specificity of MRI at detecting SPTs in irradiated hereditary retinoblastoma patients.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Included patients will undergo yearly craniofacial MRI for a period of 4 years. They will also be asked to fill out a psychological burden assessment form each visit. A potential risk of screening might be associated anticipatory anxiety, but screening also could be reassuring for patients and their parents; the investigators are not sure which will outweigh. False-positive results from MRI screening could lead to unnecessary further diagnostics leading to possible added anxiety and diagnostics (e.g., biopsies). However, this group of patients have a high risk of developing SPTs, with poor 5-year survival statistics. Early detection and therefore treatment of earlier stage (smaller) tumors, might therefore increase survival of this patient group.

Conditions

  • Retinoblastoma

Interventions

DEVICE

Magnetic resonance imaging

MR imaging protocol should include a thin-slice (3-4 mm) short TI inversion recovery (STIR) sequence or fat-saturated T2-weighted images in axial direction. Furthermore, a 3D-T1 weighted sequence with isotropic voxels will be obtained, with reconstruction in 3 directions. If suspicious lesions are detected, additional MR imaging has to be performed, including contrast-enhanced images.
