简要总结
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.

结局指标
主要结局
Diagnostic accuracy of MRI for the detection of second primary tumors in hereditary irradiated retinoblastoma
时间窗: 4 years
The primary objective of the study is to evaluate the benefit of early detection of craniofacial second primary tumors with MRI in previously irradiated hereditary retinoblastoma survivors. The main outcome measure for assessing the benefit of screening will be the diagnostic accuracy of MRI for detecting craniofacial SPTs: sensitivity (true-positive and false-negative results) and specificity (true-negative and false-positive results).
次要结局
- Feasability assessment(4 years)
