Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had choriocarcinoma with metastases to the lungs, liver and kidneys. The 5th and 6th regimens with cisplatin for choriocarcinoma failed and the patient developed brain metastases. She was then treated with four cycles of high-dose ifosfamide, carboplatin and etoposide (ICE) with blood progenitor cell support after confirming the effectiveness of ICE at normal doses. The serum human chorionic gonadotropin (hCG) level was 140,009 mIU/ml at the start of high-dose ICE and the patient tolerated this regimen well. However, the beneficial effect was decreasing with each successive course of treatment, with the lowest level of hCG at 103 mIU/ml after the fourth course. The patient did not achieve complete remission and succumbed to the disease 4 months after the last chemotherapy. The findings of the present case and a review of the related literature suggest that high-dose ICE with stem cell rescue may be considered as a viable treatment option for a multi-drug resistant choriocarcinoma or GTN.

OBJECTIVE: To investigate gestational trophoblastic neoplasia (GTN), fertility, and pregnancy outcome in molar patients who underwent routine second curettage.
STUDY DESIGN: Eighty-two patients who visited our hospital for hydatidiform mole between 2002 and 2011 were registered in this study. All patients had second curettage around the 7th day after first evacuation. We performed retrospective analysis on several factors between a remission group and a GTN group.

RESULTS: Fourteen patients (17.1%) had chemotherapy after being diagnosed with GTN. Multivariate analysis revealed that the hCG value before first evacuation was only one independent prognostic factor for GTN. The median follow-up period was 45.5 months, and 41 patients had 62 pregnancies after remission of hydatidiform mole and GTN. The fertility rate was 80% in 45 patients with desire for a baby, and 39 pregnancies (62.9%) ended in live births without congenital malformation.

CONCLUSION: The incidence of GTN was not lower in hydatidiform mole with routine second curettage. An independent prognostic factor for GTN was the hCG value before the first evacuation in molar patients. Our results suggest that routine second curettage does not affect the fertility rate or increase a risk of adverse outcomes in subsequent pregnancies.
