Background:
There is a therapeutic dilemma for the pregnant patient with malignancy requiring chemotherapy.
Case:
We had a case of a 30-year-old pregnant woman with a yolk sac tumor who underwent right salpingo-oophorectomy at 22 weeks gestation. Chemotherapy during pregnancy was postponed because of concern with the risks of the chemotherapy to the fetus. After the operation, L2 fraction of alpha-fetoprotein (AFP) depending on the affinity for Lens culinaris agglutinin (LCA) as an indicator for a maternal source of AFP had been detectable since 30 weeks gestation and elevated rapidly with advancing gestation. Tumor recurrence was confirmed clinically at 34 weeks gestation. She was induced, delivering a healthy baby, and received seven complete chemotherapy courses (cisplatin, etoposide, and peplomycin). Currently, the mother (39 months after last chemotherapy) and child are doing well.
Conclusion:
AFP-L2 may be a sensitive indicator for a yolk sac tumor derived AFP, leading to an earlier detection of tumor recurrence during pregnancy.
