Successful salvage treatment with paclitaxel, ifosfamide, and cisplatin in a patient with methotrexate‐resistant gestational trophoblastic neoplasia who developed hypersensitivity reaction to etoposide

We report a 34‐year‐old woman with recurrent gestational trophoblastic neoplasia (GTN) who showed hypersensitivity to etoposide. Computed tomography (CT) revealed a 32‐mm solid mass in the right lung and a 101‐mm cystic mass with solid components in the left side of the liver. The patient's serum human chorionic gonadotropin (HCG) level was 689 439 mIU/mL. After eight cycles of combined paclitaxel 175 mg/m2 on day 1, ifosfamide 1 g/m2 on days 2–5, and cisplatin 20 mg/m2 on days 2–5 (TIP) every 3 weeks, the serum HCG level decreased to 2.4 mIU/mL. CT scan revealed disappearance of the lung tumor and significant reduction in the solid components of the liver tumor. Then, left hemihepatectomy was performed. After 3 months, there was no evidence of the disease, and the serum HCG level normalized. Thus, TIP chemotherapy, followed by residual mass resection, might be effective for methotrexate‐resistant GTN.
