title: Choriocarcinoma following term gestation.
abstract: The current study reviews post-term choriocarcinoma at the New England Trophoblastic Disease Center (NETDC) in order to expand knowledge of its clinical features. Between June 1965 and June 1981, 366 patients with persistent gestational trophoblastic disease were managed at the NETDC and 15 (4.1%) of these patients had choriocarcinoma following term pregnancy. Post-term choriocarcinoma has a propensity for early metastasis with frequent involvement of the liver and brain. Metastases were detected in 13 (86.7%) patients with post-term choriocarcinoma at the time of diagnosis. Seven patients (53.8%) with metastatic post-term choriocarcinoma had hepatic and/or cerebral involvement. Complete remission was achieved in both patients with nonmetastatic disease and in 8 (61.5%) patients with metastatic disease. When the time interval from the antecedent term delivery to diagnosis was less than 4 months, 7 (87.5%) of 8 patients achieved complete remission. The 5 patients who died from post-term choriocarcinoma all had hepatic and/or cerebral involvement. Patients with post-term choriocarcinoma should undergo a meticulous metastatic evaluation and if metastases are detected these patients should be treated with primary combination chemotherapy and with the selective use of irradiation and surgical therapy.
