Conception After Chemotherapy for Intraplacental Choriocarcinoma: Favorable 5-Year Follow-Up of the Mother and Child.

BACKGROUND Intraplacental choriocarcinoma (IC) is a rare subtype of gestational choriocarcinoma that can be associated with placental hemorrhage and metastases to the mother and fetus. Chemotherapy can be effective in cases of placental localization and may not adversely affect fertility. This report describes a 32-year-old woman who conceived 10 months after chemotherapy for IC and achieved successful term delivery of that pregnancy. CASE REPORT A 32-year-old woman delivered her first child by vacuum extraction due to weak labor and fetal distress. The newborn presented with severe anemia, as well as elevated alpha-fetoprotein and fetal hemoglobin levels, suggesting fetomaternal hemorrhage. Placental histopathology revealed IC. Postpartum elevation of human chorionic gonadotropin levels prompted EMA-CO (etoposide, methotrexate, actinomycin D/cyclophosphamide, vincristine) chemotherapy; 7 treatment courses were completed without side effects or metastasis. Ten months after completion of chemotherapy, the patient spontaneously conceived. She subsequently delivered a healthy boy at 38+5 weeks of gestation; placental examination did not reveal malignancy. During the 5-year follow-up period, both children developed normally, and no maternal recurrence or metastasis was observed. CONCLUSIONS This report describes a case of postnatal diagnosis of IC via placental histopathology, followed by successful treatment and subsequent pregnancy within 1 year after chemotherapy completion. The findings highlight the importance of accurate diagnosis and appropriate management of IC; they support previous observations that chemotherapy does not preclude future successful pregnancies. Additionally, the report underscores the clinical challenges of IC, its implications for future pregnancies, and the need for long-term follow-up concerning both mother and child.
