Survival of Children with Trisomy 13 and Trisomy 18: A Population-Based Study from Nine U.S. States

Trisomy 13 (T13) and trisomy 18 (T18) are among the most prevalent autosomal trisomies. Both conditions are associated with a very high risk of mortality. Numerous instances, however, of long-term survival of children with T13 or T18 have prompted some clinicians to pursue aggressive treatment instead of the traditional approach of providing mainly comfort care. The purpose of this study is to examine current mortality data for these conditions.
This study is part of the National Birth Defects Prevention Network’s larger multi-state project on infant and childhood survival among individuals with birth defects. The present analysis examines survival data on children born during 1999-2007 with T13 or T18 from nine of the surveillance programs participating in the larger study. Participating programs were those that used either active surveillance or passive surveillance with follow-up case confirmation, and included Arizona, Colorado, Georgia, Illinois, Massachusetts, New Jersey, New York, North Carolina and Texas. Information on children’s vital status and selected maternal and infant risk factors was obtained from matched birth and death certificates and other data sources. The Kaplan-Meier method and Cox proportional hazards models were used to estimate age-specific survival probabilities and predictors of survival up to age five.
There were 693 children with T13 and 1,113 children with T18 identified from the participating states. Among children with T13, 5-year survival was 9.7%; among children with T18, it was 12.3%. For both trisomies, gestational age was the strongest predictor of mortality, with two-fold or greater adjusted hazard ratios seen for children born < 32 weeks gestation compared to those born at term. Females and children of non-Hispanic black mothers had the lowest mortality. Omphalocele was associated with an increased risk of death for children with T18 but not for those with T13. There were also some survival differences by state.
This study found survival estimates among children with T13 and T18 to be somewhat higher than those previously reported in the literature. This is consistent with some recent studies that reported improved survival following more aggressive medical intervention for these children. Future studies using population-based birth defect registries linked with hospital discharge and/or medical claims data could examine this issue in greater depth.
