Conclusion

Most ETTs do not respond to chemotherapy, and so hysterectomy is still the mainstay of treatment. Fertility-sparing treatment may be considered, but long follow-up is needed to prove its safety. Mixed trophoblastic tumors are rare, and their clinicopathologic presentations are unclear. Whether their behaviors are related to the proportion of different components and their best treatment option also require more research to define. For those patients with GTN who fail to respond to conventional chemotherapy, a histologic diagnosis with pathologic review is needed to rule out the possibility of mixed GTN.
