Sacrococcygeal teratoma (SCT) is the most common fetal and neonatal tumor. However, predicting factors of evolution, sequelae and relapse are still unreliable because of small-cohort studies. This study aims at identifying prenatal and postnatal prognostic factors of evolution of SCT during pregnancy, of postnatal relapse, and of medium and long-term sequelae (urinary, digestive, esthetic, psychologic) in order to improve parental counseling when the diagnosis of SCT is made during pregnancy.
