Ultra High-risk Gestational Trophoblastic Neoplasia
Ultra high-risk gestational trophoblastic neoplasia (GTN) refers to patients with World Health Organization prognostic risk scores of at least 13. The mortality risk for these patients averages 30%. Ultra high-risk GTN more frequently presents with higher tumor volume, liver and/or brain metastases, and very high human chorionic gonadotropin levels. The diagnostic evaluation must include a thorough evaluation for central nervous system disease. Prompt initiation of cisplatin - etoposide induction chemotherapy reduces the risks of early death. Collaborative services such as neurosurgery, radiation oncology, and interventional radiology may be required to manage hemorrhagic lesions.
