All patients had carried a germline mutations in the RB1 gene. The median time from retinoblastoma diagnosis to SPMN diagnosis was 19.0 years (extremes 3.4 and 39.4 years). Six of the fifteen patients died during the follow-up of their SPMN. The median interval between initial retinoblastoma diagnosis and death in the 6 patients who died of their SPMN was 18.8 years (extremes 6.2 and 34.6 years) and between diagnosis of the SPMN and death was 1.2 years (extremes 0.25 and 4 years).Discussion: Of the patients who had been treated with External Beam Radiotherapy (EBRT), 13 developed a SPMN within the previously irradiated field.Keywords: external beam radiotherapy, pediatrics, osteosarcoma, retinoblastoma, family history, second primary malignant neoplasm
