Of the children born in Hungary between 1960 and 1968, 43 were found to suffer from confirmed retinoblastoma, indicating that 1 in 30000 live births may develop retinoblastoma. This relatively low frequency may be attributed, among other things, to a lower paternal age than in other countries. Of the cases detected, 69.8% were unilateral retinoblastomas and 78% were alive at the time of the survey in 1971. The mutation rate, estimated by the so-called direct method, was 6×10-6.
