In a normal pregnancy, cells grow and surround the fertilized egg, connecting the egg to the wall of the uterus and forming the placenta, which is responsible for feeding the fetus during pregnancy.
Gestational trophoblastic disease (GTD) is a rare condition—accounting for fewer than 1 percent of all gynecologic cancers and occurring in about one of every 1,000 pregnancies in the United States, according to the American Society of Clinical Oncology. GTD is an umbrella term for a group of rare diseases in which abnormal trophoblast cells grow inside the uterus after conception, forming a tumor.
GTD is usually not cancerous, though some tumors may become cancerous and spread. The disease is generally treatable, especially if diagnosed early.
At City of Hope, our gynecologic oncologists are trained and experienced in treating cancerous GTD. They work with a multidisciplinary team of cancer experts and other clinicians, collaborating in designing a care plan tailored to each patient’s needs and goals. Each patient-focused treatment plan also includes supportive care services designed to help the patient manage, and when possible prevent, side effects of the disease and its treatment.
GTD is such an important focus at City of Hope, in fact, that each of our hospitals has a Gynecologic Cancer Center, focusing on treating women with cancer of the reproductive organs.
This overview will cover the basic facts about GTD, including:
If you believe you may be experiencing symptoms of GTD and want to schedule an appointment for diagnostic testing, or if you’re interested in a second opinion on your GTD diagnosis and treatment plan, call us or chat online with a member of our team.
Risk factors for GTD vary. Various risk factors associated with a woman’s pregnancy may increase her risk.
They include:
"The care I received at City of Hope still amazes me. I felt genuine concern and empathy. If I was having a meltdown moment, someone was there to hand me a tissue. No one made me feel silly about the questions I had, and my questions were answered. At City of Hope, I felt like my doctor cared, and that he takes the time to care. I don’t see him or the members of my care team checking their watches during an appointment with me. That alone is extraordinary to me."
GTD is usually identified as a hydatidiform mole (a molar pregnancy) or as gestational trophoblastic neoplasia (GTN). Each disease is categorized into various subtypes.
They include:
The symptoms of GTD may be difficult to identify or may be mistaken for other pregnancy-related events.
Symptoms may include:
Tests that may be used for diagnosing GTD include:
Treatments for GTD typically include:
At our Gynecologic Cancer Centers, we treat GTD using standard-of-care and, when appropriate, innovative precision medicine treatments.
Surgical and chemotherapy treatments for GTD may cause a number of side effects that affect your quality of life, including pain, malnutrition and depression. Our multidisciplinary care team includes gynecologic oncologists and supportive care therapists who work together to design treatment plans that are tailored to you and your needs, while reducing side effects of the cancer and its treatment as much as possible.
We understand that managing these side effects is an important part of recovery. The team approach at City of Hope is designed to put patients in the middle of their care, treating the disease and managing side effects in real time so they can get back to their lives.
Cancer Treatment Centers of America® (CTCA) is now City of Hope®, joining forces to expand patient access to personalized, comprehensive cancer care.
Supportive care therapies that may be recommended to help GTD patients stay strong and maintain their quality of life include:
