    "abstract": "Due to resistance and intolerance to chemotherapy, localized lesion resection may be required in some patients with Gestational trophoblastic neoplasia (GTN), which may lead to massive bleeding. In this case report, we describe the successful use of high-intensity focused ultrasound (HIFU) as an effective pretreatment method for surgical procedure in a patient with GTN to reduce the perioperative risk and the impact on fertility.\nA 26-year-old woman was diagnosed with high-risk GTN (FIGO Stage III: 12 prognostic scores) after a hydatidiform mole. The fifth chemotherapy cycle was interrupted due to severe chemotherapy toxicity. However, the uterine lesion was still present and the beta-human chorionic gonadotropin (\u03b2-hCG) level was not restored to normal. Therefore, ultrasound-guided HIFU was performed as a pretreatment method to shrink the lesion and prevent massive bleeding during localized lesion resection. The effectiveness of ablation was evaluated immediately using contrast-enhanced ultrasound and Color Flow Doppler ultrasonography. One month after HIFU treatment, the uterine lesion was completely resected under hysteroscopic surgery. During the surgery, HIFU was found to have shrunk the lesion and there was minimal bleeding (5\u2009mL). The uterine cavity morphology and menstruation returned to normal after surgery. The patient has showed no signs of recurrence as of one-year follow-up.\nUltrasound-guided HIFU ablation may be a new choice for high-risk GTN patients with chemoresistance or chemo-intolerance. As a noninvasive pretreatment method, HIFU can shrink the uterine lesion, and reduce the risk of bleeding with no obvious effect on fertility.",
