Choriocarcinoma following term gestation.
Gynecologic Oncology
|January 1, 1984
Summary
Post-term choriocarcinoma, a rare form of gestational trophoblastic disease, often presents with early liver and brain metastases. Prompt diagnosis and combination chemotherapy improve remission rates, especially when treatment begins within four months of delivery.
Area of Science:
- Gynecology
- Oncology
- Pathology
Background:
- Gestational trophoblastic disease (GTD) encompasses a spectrum of placental-related tumors.
- Choriocarcinoma following term pregnancy is a rare but aggressive subtype of GTD.
Purpose of the Study:
- To review clinical features of post-term choriocarcinoma.
- To identify prognostic factors and optimize management strategies.
Main Methods:
- Retrospective review of 366 patients with persistent GTD managed at the New England Trophoblastic Disease Center (NETDC) from June 1965 to June 1981.
- Analysis of clinical data for 15 patients diagnosed with post-term choriocarcinoma.
Main Results:
- Post-term choriocarcinoma occurred in 4.1% of patients with persistent GTD.
- Metastases were detected in 86.7% of cases at diagnosis, frequently involving the liver and brain (53.8%).
- Complete remission was achieved in 61.5% of metastatic cases, with higher remission rates (87.5%) when diagnosed within 4 months of delivery.
Conclusions:
- Post-term choriocarcinoma necessitates thorough metastatic evaluation due to high rates of early spread.
- Combination chemotherapy is recommended for metastatic disease, with selective use of irradiation and surgery.
- Timely diagnosis and treatment are crucial for improving patient outcomes.
