Sacrococcygeal teratoma: the 13-year experience of a tertiary paediatric centre.

AIM: To describe the management, morbidity and mortality of infants admitted to a tertiary paediatric hospital in New South Wales, Australia with a diagnosis of sacrococcygeal teratoma (SCT).

METHODS

All neonates admitted to the neonatal intensive care unit with a SCT between January 1996 and December 2008 were included in this retrospective review. Data collected included maternal and neonatal demographics, time of diagnosis, tumour characteristics, surgical treatment, operative complications and outcomes.

RESULTS

Seventeen infants with a diagnosis of SCT were included in the study. Of these infants, the majority (70%) were born at term, and eight had a prenatal diagnosis made during the second trimester. Associated anomalies were detected in seven infants (41.8%), with renal anomalies being the most common. Tumour histology included mature (50%, n= 8), yolk sac tumour (18.75%, n= 3), immature (6.25%, n= 1) and mature with mixed elements (25%, n= 4). Recurrent disease occurred in two infants within 4-18 months of the primary resection, with one infant suffering a second recurrence. Only one child died prior to surgery, giving a survival rate of 94%, and mean age at follow-up was 32 months. Long-term sequelae found in four babies included revision of scar, vesicoureteric reflux, post-surgical neurogenic bladder and osteotomy for hip dysplasia.

CONCLUSIONS

The overall survival of neonatal SCT is high. While this is a small series, our results are consistent with the literature. Important components of management include timely diagnosis, multidisciplinary planning, long-term follow-up and intervention for functional sequelae.
