Female prevalence is particularly higher with a female-to-male ration of 3-4:1. Sacrococcygeal teratoma alone is diagnosed at birth in one out of 40,000 humans. Given the current human population and birth rate, this equals five per day or 1800 per year. Add to that number sacrococcygeal teratomas diagnosed later in life, and teratomas in other locales, and the incidence approaches 10,000 new diagnoses of teratoma per year. Teratoma, from the Greek teratos (‘of the monster’) and onkoma (‘swelling’), is a term first applied by Virchow in 1869 to ‘sacrococcygeal growths’. 1 Teratomas are composed of multiple tissues foreign to the organ or site from which they arise.
Sacrococcygeal teratoma: has chemotherapy improved survival? Dewan PA, Davidson PM, Campbell PE, Tiedemann K, Jones PG. Case records of 57 patients (50 female, 7 male) with sacrococcygeal teratoma who were treated at the Royal Children's Hospital in Melbourne between 1948 and 1986 were reviewed.
J Ultrasound Med 2018; 37:2003. Outcome • Antenatal diagnosed SCT – overall survival of ~75%. • If live born – >90% survival. • Recurrence occurs in 10–20% of benign SCTs and in ~30% of malignant stage 1 SCTs (often late presenters).
This treatment strategy resulted in a 6-year event-free survival (EFS) rate of 82%. Boys who developed recurrent disease received salvage therapy with four cycles of standard-dose cisplatin, etoposide, and bleomycin (PEb), with a 6-year survival rate of 100%.
Teratoma 20150424 2. Introduction due to abnormal differentiation of fetal germ cells that arise from the fetal yolk sac Teratomas are typically found in the midline or gonads. Sacrococcygeal - 40% Ovary - 25% Testicle - 12% Brain - 5% Other (including the neck and mediastinum) - 18% 3. Fetal sacrococcygeal teratomas diagnosed in utero carry a high risk of preterm delivery (50%), a mortality rate of 15-35%, and a morbidity rate of 12-68% [1,2,3,4,5]. Prognosis seems to be related not to the size of the mass but rather to its content and extent. Sacrococcygeal teratomas are the most common tumors in newborns with an incidence of 1 per 20,000 - 40,000 births. They range from benign well differentiated cystic lesions to malignant solid masses.

For malignant teratomas surgery is usually followed by chemotherapy. Recent studies report that chemotherapy in conjunction with radiotherapy may increase the duration and rate of survival in patients with immature teratoma  . Cisplatin/carboplatin-based drugs have proven to be the most effective chemotherapy medications for these tumors . Sacrococcygeal teratoma is one of the most frequently prenatally diagnosed neoplasias. Obstetric ultrasound has a role in the diagnosis and management of these tumors during pregnancy.

All three of the patients with malignancy had bowel or bladder dysfunction, and two of the three developed pulmonary and hepatic metastases. The operative mortality rate was less than four per cent. Survival rate in the benign tumors was 100 per cent. 2015-04-29 risk fetal sacrococcygeal teratomas.
Benign SCTs have a significant recurrence rate of approximately 7%. Close follow-up with serial AFP level monitoring should be done for 5 years after initial tumor resection and coccygectomy. The survival rate for malignant SC-GCTs with distant metastasis was unfavorable in the present study.
