Our long experience with prenatal diagnosis and planning for optimum care allows us to offer the highest quality treatment whether intervention is indicated before or after birth.
Under the direction of Dr. Michael Harrison, the Fetal Treatment Center was the first institution to develop fetal surgery techniques. The first open fetal surgery in the world was performed at UCSF over 2 decades ago. We presently have more experience with fetal surgery and endoscopic fetal intervention (FETENDO fetal surgery) than any other institution in the world. We are dedicated to Sacrococcygeal teratoma research and treatment innovation.
Sacrococcygeal teratoma (SCT) is an unusual tumor that, in the newborn, is located at the base of the tailbone (coccyx). This birth defect is more common in female than in male babies. Although the tumors can grow very large, they are usually not malignant (that is, cancerous). They can usually be cured by surgery after birth, but occasionally cause trouble before birth.

Most fetuses with sacrococcygeal teratoma do well with surgical treatment after birth. These tumors are generally not malignant. Babies with small tumors that can be removed along with the coccyx bone after birth can be expected to live normal lives, although they should be followed for development of tumors later in life, using a simple blood test for alpha feto-protein. Fetuses with larger tumors or tumors that go up inside the baby’s abdomen will require more complex surgery after birth, but in general do well. Again, they will have to be followed with blood tests for several years. Fetuses with very large tumors, which can reach the size of the fetus itself, pose a difficult problem both before and after birth.

In order to determine the severity of your fetus's condition it is important to gather information from a variety of tests and determine if there are any additional problems. These tests along with expert guidance are important for you to make the best decision about the proper treatment.

Most newborns with SCT survive and do well. Malignant tumors are unusual. Fetuses with large cystic SCTs rarely develop hydrops and therefore are rarely candidates for fetal intervention. These cases are best handled with surgical removal of the tumor after delivery. A Cesarean-section delivery of the baby may be necessary if the tumor is larger than 10 cm.
All babies with SCT should be delivered at a tertiary center with pediatric surgery expertise. Tumors larger than 10 cm in diameter will require C-section delivery. The neonatologist will provide support in the intensive care nursery until the baby is stable enough for surgery.
