Clinical Trial: SPT Screening in Irradiated Hereditary Retinoblastoma Survivors
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational
Official Title: Multicenter Implementation of MR Imaging Studies in Irradiated Hereditary Retinoblastoma Survivors for Assessment of the Value of Craniofacial MRI Screening for Early Detection of Second Craniofacial
Brief 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 poo

Current Primary Outcome: Diagnostic accuracy of MRI for the detection of second primary tumors in hereditary irradiated retinoblastoma [ Time Frame: 4 years ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- 5-year survival [ Time Frame: 9 years ]A secondary objective is to assess the 5-year survival of second primary tumors (SPT) found by screening, SPTs missed by screening, and the non-SPT patients
- Descriptive statistics [ Time Frame: 4 years ]Recording and monitoring location and characteristics (clinical, radiological, histological, treatment) of patients with SPTs: total number of patients included, median follow-up time + range, number of asymptomatic SPTs detected by screening, number of symptomatic SPTs missed by screening, number of SPTs developed after the end of screening, number of SPTs that were totally resected, location of tumor, type of tumor, size of tumor
- Feasability assessment [ Time Frame: 4 years ]Assessment of the feasibility of such this screening program: (a) percentage of patients (or family) willing to participate; (b) compliance of patients and their families to the screening program
- Assessing the psychosocial burden or benefit [ Time Frame: 4 years ]Once a year during the visits, the patient will be asked to fill out the Hospital Anxiety and Depression Scale (HADS).
Original Secondary Outcome: Same as current
