ABSTRACT
OBJECTIVES:
There is a paucity of long-term follow-up data for children with intracranial ependymoma (IE) and medulloblastoma (MB). What happens to these children 20, 30, or 40 years after diagnosis? Do they have potential for a normal lifespan? The purpose of this study was to ascertain the long-term survival potential in children with MB or IE who have survived 5 years from diagnosis.METHODS:
A retrospective analysis was conducted using the SEER Program. Children (ages 0-19 years) from 1973 to 2011 with a diagnosis of MB or IE were identified. A cohort was created of potentially cured patients who survived 5 years from diagnosis. Cox proportional hazards models and Kaplan-Meier estimates were utilized to analyze long-term survival.RESULTS:
We identified 876 patients with MB and 474 patients with IE who were alive 5 years from diagnosis. Patients with MB had a 30-year overall survival (OS) and cancer-specific survival (CSS) of 70.2% and 80.1%, respectively. Patients with IE had a 30-year OS and CSS of 57.3% and 68.8%, respectively. When comparing MB with IE, MB had improved CSS (P = 0.04) and trended toward increased OS (P = 0.10).CONCLUSIONS:
A significant number of deaths due to disease occur for several decades after treatment for both IE and MB. Despite this, the potential for long-term survival exists in 5-year survivors of both histologies. If alive at 5 years from diagnosis, patients with MB tend to have a lower risk of death from disease compared to those with IE.Palabras clave
