title: [Prevalence of etinoblastoma in the Midi-Pyrenées area].
abstract: The frequency of retinoblastoma was estimated in southwest France (Midi-Pyrénées) during the 1950-1969 period. Twenty-three cases were detected among 507 157 liveborns. After correcting for the probability of ascertainment of patient, the estimated frequency is 1 per 15 849 births. The proportion of unilateral cases is estimated 91 percent after correcting for the higher probability of ascertaining bilateral cases.
