What is Gestational Trophoblastic Disease: Treatment of Hydatidiform Mole and Choriocarcinoma?

GTD spectrum includes hydatidiform mole, invasive mole, choriocarcinoma, placental site and epithelioid trophoblastic tumors.

Complete hydatidiform mole results from fertilization of empty ovum with karyotype usually 46,XX of paternal origin.

GTN diagnosis follows molar pregnancy or any pregnancy with persistent or rising hCG indicating malignant transformation.

FIGO scoring system stratifies low-risk (score 0-6) versus high-risk (score 7+) disease guiding treatment.

Beta-hCG serves as exquisitely sensitive tumor marker for diagnosis, treatment response and surveillance.

Symptoms

Vaginal bleeding during pregnancy with passage of grape-like vesicles characterizes molar pregnancy.
Excessive uterine size for gestational age, hyperemesis gravidarum, hyperthyroidism manifest molar pregnancy.
Pre-eclampsia before 20 weeks gestation strongly suggests molar pregnancy.
Pulmonary, vaginal or central nervous system metastases manifest with respective organ-specific symptoms.
Markedly elevated beta-hCG levels with characteristic ultrasound snowstorm pattern characterize molar pregnancy.

Risk Factors

Extremes of maternal age including very young or advanced maternal age increase molar pregnancy risk.
Previous molar pregnancy increases recurrence risk requiring careful monitoring of subsequent pregnancies.
Asian and Latin American populations have higher reported incidence of gestational trophoblastic disease.
Nutritional factors including beta-carotene and animal fat intake have been associated with risk.
Blood type A women with blood type O partners have increased relative risk in some studies.

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • First-trimester vaginal bleeding with markedly elevated hCG and characteristic ultrasound warrants molar pregnancy evaluation.
  • Persistent or rising hCG following pregnancy or molar evacuation requires immediate GTN evaluation.
  • FIGO risk-stratification, metastatic workup including chest, abdomen, pelvis, brain imaging guides treatment.
  • Severe respiratory symptoms, neurological symptoms, severe pre-eclampsia warrant urgent evaluation.
  • Multidisciplinary GTD center referral with experienced gynecologic oncologists optimizes outcomes.

Treatment Methods

01
Suction dilation and curettage represents primary treatment for molar pregnancy with hCG surveillance afterward.
02
Single-agent methotrexate or actinomycin D for low-risk GTN provides excellent cure rates.
03
Multi-agent EMA-CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) for high-risk GTN.
04
Brain metastases require intrathecal methotrexate, whole brain radiation or stereotactic radiosurgery.
05
Comprehensive multidisciplinary care with gynecologic oncology, beta-hCG surveillance until normalization for at least 6 months, contraception during surveillance, fertility preservation considerations, salvage therapy with EMA-EP or BEP for resistant disease, hysterectomy for placental site trophoblastic tumor, long-term follow-up with annual hCG, and pregnancy counseling for subsequent pregnancies provides excellent outcomes with cure rates exceeding 95% in most patients with GTD.

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
