Sacrococcygeal teratoma (SCT) is the commonest neonatal neoplasm. Its long-term effects are important in prenatal counseling and the delivery of an appropriate postoperative plan.
To determine the long-term functional outcome after SCT excision in a UK regional center.
Follow-up data for all patients with a SCT excised at the John Radcliffe Hospital in Oxford was collected retrospectively from notes and prospectively in clinic visits.
Clinical evidence of bowel or bladder impairment, mortality.
Over a 14-year period, 18 patients had a histologic diagnosis of SCT. Nine patients (50%) were born, 7 (39%) were terminated, and 2 (11%) were stillbirths. Of the 9 patients who had SCT resection, 4 (44%) were antenatally diagnosed. There were no perioperative deaths and alpha-fetoprotein levels normalized by 6 to 12 months after tumor resection. Median follow-up of patients was 30 months (range: 6 to 132 mo) with 1 patient lost to follow-up at 6 months, although he was asymptomatic at the time. Three patients developed urologic complications (2 within 1 year of tumor resection), including 2 patients with neurogenic bladder dysfunction and 1 patient with detrusor sphincter dyssynergia.
Approximately one-third of patients will develop major urologic complications after resection of SCT. Routine ultrasonography in the first postoperative year after tumor resection may help to identify patients with neuropathic bladder at the early stage and predict late complications. Parents need to be aware of this potential long-term complication during prenatal counseling and the need for regular long-term follow-up with the pediatric surgical team.

    ABSTRACT: Teratomas are composed of multiple tissues foreign to the organ or site in which they arise. Their origin is postulated by 3 theories one of which is the origin from totipotent primodial germ cells. Anatomically, teratomas are divided into gonadal or extragonadal lesions and histologically they are classified as mature or immature tumors. Teratomas are mainy isolated lesions and may occur anywhere in the body. In the neonatal age group most of these tumors are benign and occur mainly in the sacrococcygeal area followed by the anterior mediastinum. Diagnosis is usually established prenatally and may require intervention in compromised fetuses. Postnatal imaging with ultrasound, CT scan or MRI provides useful information for surgical intervention. Complete surgical excision is the treatment of choice for neonatal teratomas. Alpha feto protein is the tumor marker of choice and is particularly useful for assessing the presence of residual or recurrent disease.

    ABSTRACT: To propose long-term follow-up protocol to analyse clinical and functional aspects and evaluate the Quality of Life (QoL) of patients with Sacrococcygeal Teratoma (SCT). The long-term follow-up of 14 out of 28 patients has been assessed through the retrospective review of data related to antenatal diagnosis, obstetric pathology and surgery, collected from July 1985 to December 2009. It has been accomplished by analysing functional and aesthetic outcomes and the QoL experienced by the patients with an average observation range of 121 months for each patient. Concerning the anorectal functionality, 14% of patients reported impairment of fecal continence while 36% had completely normal bowel habits. Other health problems varying from urinary incontinence to neurogenic bladder were reported by 36% of patients. Dealing with the functionality of lower limbs, 20% of patients exhibited minor dysfunctions while 7% major ones. Optimal aesthetic outcome of the surgical scar has been reported only by 21% of the specimen. The evaluation of QoL pointed out that 64% of patients are moderately satisfied while 36% presented problems. We believe that functional sequelae should play an important role during antenatal counselling and that the urological and anorectal follow-up for SCT patients should be long-term evaluated. Furthermore, aesthetic aspects and psychological support should be taken into account carefully especially during childhood.
