Primary spinal germ cell tumors are rare, and spinal nongerminomatous germ cell tumors represent an even rarer subset for which no standard therapy has been established. The authors report the case of a 24-year-old woman with multifocal primary spinal germ cell tumors scattered from T-12 to L-5 that consisted of yolk sac tumor and mature teratoma. After diagnostic partial resection, the patient was treated with 30 Gy of craniospinal irradiation and 30 Gy of local spinal irradiation, followed by 8 courses of chemotherapy based on ifosfamide, cisplatin, and etoposide (ICE). Salvage surgery was also performed for residual mature teratoma components after the third course of ICE chemotherapy. Chemotherapy was continued after the operation, but ifosfamide was entirely eliminated from the ICE regimen because severe myelosuppression was observed after previous courses. The patient remains recurrence free as of more than 5 years after the completion of chemotherapy. This case suggests that this treatment strategy is an effective option for primary spinal yolk sac tumor.
