Background   Undifferentiated embryonal @entity409 (UELS) accounts for only 9 to 15% of all malignant @entity96 in @entity1 . Typically, UELS occurs in older @entity1 and presents as an abdominal mass. Most UELS are unresectable because of the later diagnosis. The outcome of UELS is very poor, with a 5-year overall survival of   <   37.5%. Transarterial chemoembolization (TACE) has been reported to be an effective modality for unresectable @entity96 . To investigate the effects of TACE on UELS in @entity1 , we present two cases of @entity1 with UELS who underwent TACE and surgical resection in our center within the past 10 years. Methods   In this study, two @entity1 with UELS were treated using TACE with @entity900 , @entity632 , and iodized oil. The size of the @entity5 was measured before and after TACE using ultrasonography. Routine was also given before and after surgical resection. Side effects were recorded. Both @entity1 had follow-up. Results   After interventional therapy, both @entity1 presented with @entity409 without @entity299 . One @entity1 had @entity236 . The size of the @entity5 was reduced by 23% to 31% after TACE. The @entity5 were completely removed by surgical procedures after 4 weeks of TACE in both @entity1 . One @entity1 survived free of disease for 1   year, and the other survived free of disease for 9 years. Conclusion   TACE yielded satisfactory results for unresectable UELS in @entity1 , with lower dosage of chemotherapy and fewer side effects. It may be applied as a preoperative therapy for @entity1 with unresectable UELS.
