Gestational Trophoblastic Disease

The UofL Brown Cancer Center is dedicated to providing you the best care for gestational trophoblastic disease.

Overview

UofL Brown Cancer Center is dedicated to providing you the best care for gestational trophoblastic disease. In our Multidisciplinary Gastrointestinal Cancer Clinic we bring together a team of gynecologic oncologists, radiation oncologists, reconstructive surgeons, colorectal surgeons, pathologists and radiologists to collaborate and provide a personalized treatment for you.

Gestational trophoblastic disease is a rare form of cancer in women. It happens when the egg and sperm do not combine correctly. Gestational trophoblastic disease starts in the uterus (womb) during the time women can have children.

Gestational trophoblastic disease may first occur as a molar pregnancy. A molar pregnancy is when the egg and sperm join but do not develop into a baby. Instead, the tissue looks abnormal and has many cysts. A molar pregnancy is not cancer and does not go outside of the uterus.

After a molar pregnancy, a woman may develop a gestational trophoblastic tumor. This happens when the abnormal tissue comes back or spreads outside of the uterus. This is sometimes called an invasive mole, choriocarcinoma, or placental site trophoblastic tumor. Sometimes this can happen after a normal pregnancy.

Types of Gestational Trophoblastic Disease

There are several types of gestational trophoblastic tumor. These include:

  • Complete mole: this is confined to the uterus. The tumor looks like a cluster of grapes.
  • Partial mole: this is similar to a complete mole, but parts of a baby may be present. However, the baby is very abnormal and cannot live.
  • Invasive mole: this happens when a molar pregnancy invades the muscle of the uterus
  • Placenta-site trophoblastic tumor: cancer is found in the place where the placenta was attached.
  • Choriocarcinoma: cancer has spread to other places in the body

Risk Factors

There are several risk factors. These include:

  • Younger age with pregnancy
  • Older age with pregnancy
  • History of previous gestational trophoblastic disease
  • Asian descent
  • Family history of gestational trophoblastic disease

Having these risk factors does not mean that you will get gestational trophoblastic disease. However, if you have these risk factors, discuss them with your doctor.

Some symptoms include:

  • Abnormal bleeding in pregnancy
  • Severe nausea and vomiting in pregnancy
  • Larger uterus in pregnancy
  • Severe hypertension in pregnancy
  • Abnormal ultrasound in pregnancy
  • High pregnancy hormone levels (hCG) in pregnancy
  • Continued bleeding after pregnancy

These symptoms do not mean you definitively have gestational trophoblastic disease. However, if these symptoms are present, ask your doctor.

Gestational trophoblastic disease can be hard to diagnosis. It may start looking like a normal pregnancy. However, the woman may develop abnormal bleeding, ultrasound findings, or labs. These tests may be used to diagnose gestational trophoblastic disease:

  • Ultrasound: abnormal tissue is seen in the uterus
  • Pregnancy hormone levels (hCG): levels will be really high
  • Biopsy of abnormal tissue

A definitive diagnosis of gestational trophoblastic disease or molar pregnancy can only be made after surgery to remove the pregnancy. Biopsies of other disease sites may be needed to diagnose the disease

Surgery

Gestational trophoblastic diseases may be treated first with surgery. The type of surgery will depend on your age, the type of gestational trophoblastic disease, and your plans for having children in the future. Possible surgeries include:

  • Dilation and Curettage (D&C): removal of the pregnancy using suction from the uterus through the vagina.
  • Hysterectomy: removal of the uterus and cervix to removal the disease.

Chemotherapy

Chemotherapy may be used to treat gestational trophoblastic disease if it recurs or has spread outside of the uterus. Chemotherapy is given to kill the cancer cells in your body. You and your doctor will determine if this is right for you based on where the cancer has spread and other risk factors.

Radiation Therapy

Radiation therapy may be used to kill cancer cells if they have spread to places like the brain, spine, or lungs.

Our doctors at UofL Brown Cancer Center are proudly part of UofL Physicians and the UofL School of Medicine.

We believe knowledge comes from questioning the status quo, discovering more about disease and using that knowledge to improve the health of our community. Our physicians are the teachers and researchers at the UofL School of Medicine, involved in the research and development of new treatments and cures for cancer. This means you receive the most advanced and appropriate treatment, even for complex or rare conditions.
