Gestational Trophoblastic Disease
- Gestational trophoblastic neoplasia (GTN) is defined by a plateaued, rising, or prolonged elevated β-hCG value after molar evacuation; histologic diagnosis of choriocarcinoma, invasive mole, placental site trophoblastic tumor, or epithelioid trophoblastic tumor; or identification of metastasis after molar pregnancy evacuation.
- Once a diagnosis of GTN has been made, the WHO prognostic score and FIGO 2000 staging are the best tools for establishing prognosis and treatment.
- Treatment for low-risk GTN confined to the uterus may include a second suction curettage as 40% of patients treated with second curettage instead of single-agent chemotherapy had a β-hCG normalization within 6 months and avoided chemotherapy.
- Patients with high-risk metastatic GTN should be treated by individuals who have experience in treating this relatively rare disease.
