Fetal Intendance | Sacrococcygeal Teratoma (SCT)
What is a Sacrococcygeal Teratoma?
A sacrococcygeal teratoma / SCT is a tumor that develops in a baby in utero. It appears in the lower dorsum and buttocks of a baby at the base of the tailbone (coccyx). Some tumors are diagnosed in utero, others at birth.
Sacrococcygeal teratomas / SCTs are rare, occurring in about one in 35,000-forty,000 births. Even so, in newborns with tumors, they are one of the most mutual types to develop. Females are four times more than likely than males to be affected by these tumors. The cause of SCT is not known.
An SCT is a tumor that grows from germ cells, which are the same cells that requite rise to a sperm or an egg. These tumors are made upwards of cells that tin resemble whatsoever type of tissue in the trunk such as bone, nerve, teeth, muscle, and and then on. These tumors tin abound fast and get very large. They can be located both inside and outside the pelvis of a baby.
If your babe develops this blazon of tumor, you lot likely will not experience any symptoms early in the pregnancy. Later, the baby can develop disease quite rapidly and become very sick. In some instances, the mother can develop "maternal mirror syndrome" and get very ill likewise.
Tumor Classification
Sacrococcygeal teratomas / SCTs are grouped according to the corporeality of tumor nowadays inside and/or outside the baby.
- Type Itumors are completely external (outside the body) and hands identified during a prenatal ultrasound or at nativity.
- Blazon IItumors are mostly external only a portion is inside the body.
- Type Iii tumors are mostly internal but a portion is outside the trunk.
- Blazon IVtumors are completely inside the baby's body and cannot be viewed externally. They are commonly recognized belatedly, and they have the highest rate of malignancy.
Most SCTs are beneficial (not cancerous).
SCT Diagnosis and Evaluation Evidence
Diagnosis
The majority of SCTs are diagnosed in utero. This typically occurs early in the second trimester during a routine ultrasound when a mass can be seen on the baby'due south buttocks.
Information technology is at this point that most of our patients affected past SCT are referred to the Cincinnati Children's Fetal Care Heart. Hither, we'll work with y'all to assess the severity of your case, create a plan for the remainder of your pregnancy, and help you empathize what to wait later delivery.
These tumors sometimes grow apace and reach a very large size. In lodge to grow, the tumor requires a lot of blood period. As a consequence, your infant's heart works hard to pump blood to the tumor. The larger the tumor, the harder the baby's eye must piece of work.
As the middle increases its output, the baby'south kidneys will as well receive more than claret flow and consequently make more urine. This increased urine production can lead to excessive amniotic fluid building upwardly inside the uterus. This condition is called polyhydramnios and reflects a progression of the physiologic changes associated with SCT. Polyhydramnios is suspected if your uterus measures larger than it should at a given week in your pregnancy.
In the most severe cases, the tumor tin can abound so large that the baby'due south heart can't keep up, eventually leading to heart failure in the fetus (hydrops).
Evaluation
We typically see a mother with a fetal SCT within two weeks of her initial diagnosis. Your nurse-coordinator will speak with you and arrange the following tests and meetings during your visit.
- An ultrasound of the baby, where we comprehensively look at the baby and specifically expect at the claret supply, size and characteristics of the tumor
- An MRI of the babe, to get more than detailed views of the tumor, the infant's spine and the surrounding structures in the baby's pelvis
- A fetal echocardiogram, to assess how hard your babe'due south heart is working
- A meeting with our social worker to assist with specific needs that you may have
After your tests are complete, our team of experts from maternal-fetal medicine (MFM), pediatric surgery, neonatology, genetics, cardiology and radiology will discuss the results and then encounter with you in a team coming together. The important features of the team meeting include:
- Introducing the care team that will exist involved both before and later your infant is born
- Reviewing the studies with yous that led to the diagnosis and hash out their implications
- Describing the options for prenatal treatment if needed
- Developing a programme for the intendance of the rest of your pregnancy and the delivery
- Describing the typical evaluation, treatment and long-term outcome for your baby afterward it is born
Compassionate, Expert Care
The Fetal Care Center offers comprehensive diagnostic tests and the latest treatments for sacrococcygeal teratoma / SCT. Just equally important, our team of specialists takes time to explicate test results, answer questions and hash out treatment options. We understand that parents are facing unique challenges, and nosotros provide as much support as possible every stride of the way. Extensive experience and enquiry allow our team to treat the virtually complex cases of SCT.
Planning for Delivery
You should evangelize in a hospital with a level III neonatal intensive intendance unit of measurement (NICU) available for the specialized medical and surgical care that your babe will require afterward nascency.
For patients who are local or plan to deliver locally, you volition deliver at one of our maternity hospitals (Academy of Cincinnati Medical Heart or Good Samaritan Infirmary), and your babe will be transferred to the Cincinnati Children's NICU.
Early delivery is mutual in pregnancies affected by SCT. Additionally, considering of the typically big size and fragile nature of the tumor, in most cases we recommend commitment by cesarean section.
Managing Pregnancy with SCT Bear witness
After your initial evaluation, if you choose to remain in our care, we will continue to follow your baby's health closely with frequent ultrasounds and fetal echocardiograms. Information technology also volition exist of import to monitor your health with additional loftier-risk care.
Even babies with small-scale tumors can rapidly become ill despite appearing to be well earlier in the pregnancy. As the pregnancy progresses, your risks increase for developing preterm labor, preeclampsia and maternal mirror syndrome. Therefore, later on thirty weeks of pregnancy, your MFM may recommend an amniocentesis to assess the maturity of your baby's lungs. If the lungs are adequately developed, an early delivery might be recommended to reduce the risks for your baby afterwards in pregnancy.
SCT Handling Options Show
Most cases of sacrococcygeal teratoma / SCT are treated subsequently birth. Your baby will crave surgery to remove the tumor within a mean solar day or 2 after delivery.
When the fetus becomes very sick just is too early to deliver, open up fetal surgery may be an option. The procedure is called in utero debulking. "Debulking" means removing well-nigh of the tumor to reduce the strain on the infant'southward heart.
For the in utero debulking, an incision volition be made in the mother'due south tummy and uterus. The baby's bottom and legs will be brought out from the uterus allowing the surgeons to remove the external portion of the tumor. The residue of the tumor volition be removed during a surgery after your baby is born.
After the debulking, the baby is placed back into the uterus, and your uterus and tummy are closed. You lot are given medications to reduce the risk of preterm labor.
The goal of the procedure is to remove well-nigh of the tumor to reduce the stress on your infant's heart. This allows your baby to recover while inside your uterus for the rest of the pregnancy.
Fetal surgery is not an pick if the baby is and then sick that it will not tolerate the functioning or if there are signs of maternal mirror syndrome. Considering mirror syndrome may be life threatening for the mother, firsthand delivery is the best grade of handling in these cases.
What Will Happen Later Delivery? Show
After you deliver, your baby will exist transferred to the NICU and stabilized. Once stabilized, within the first day or ii of life, your baby volition take surgery to remove the tumor.
While most SCTs are beneficial, some exercise become malignant (cancerous). With larger tumors, in that location is a slightly higher chance of malignancy or recurrence. These tumors tend to answer very well to chemotherapy.
The survival rate for babies undergoing open fetal surgery is approximately 50%. The survival charge per unit for babies not needing fetal intervention is greater than 90%.
Your child will require follow-up care for at least the first iii years of life to check for signs of recurrence. The majority of children born with SCT do well in terms of overall long-term wellness, but boosted specialty intendance may be needed. Complications from SCT can include damage to the anus and rectum, injury to the pelvic muscles, float and bowel dysfunction, and problems of prematurity (often related to the evolution of the lungs). Nosotros partner with specialists throughout Cincinnati Children's as needed to coordinate your infant'due south care.
