General cancer screening practices among adult survivors of retinoblastoma: Results from the Retinoblastoma Survivor Study.

We assessed breast, cervical, and colorectal cancer screening practices in adult retinoblastoma (Rb) survivors and non-Rb controls. We found that most Rb survivors adhered to general population cancer screening recommendations. Rates did not differ among Rb survivors and non-Rb controls, or among survivors by laterality, even though bilateral survivors reported higher levels of concern about future health and cancer risk. Older age, being overweight/obese, and lack of recent contact with medical personnel were independently associated with decreased utilization of Pap smear among female Rb survivors. Future studies are warranted to determine whether these associations might provide an opportunity for intervention.
