Purpose:
The lungs are the most common site of metastasis in patients with gestational trophoblastic neoplasia. We investigated surgical management and prognostic factors of patients with refractory gestational trophoblastic neoplasia to assess the value of lung metastasis resection.
Patients And Methods:
The clinical data of patients with refractory gestational trophoblastic neoplasia and lung metastasis treated at Peking Union Medical College Hospital from January 2005 to December 2020 were retrospectively analyzed. Surgical characteristics and survival outcomes were analyzed.
Results:
In total, 213 patients with refractory gestational trophoblastic neoplasia and lung metastasis were screened, and 148 patients who underwent unilateral lung resection were analyzed. Patients' median age was 32 years. Lobectomy was performed in 65.5% of patients, while wedge resection was performed in 34.5%. The rate of postoperative complications was 12.2%. The pathological rate was 66.2%. Video-assisted thoracoscopic surgery showed better surgical characteristics than thoracotomy did. Compared with lobectomy, wedge resection had a shorter operative time, shorter duration of chest tube placement, shorter postoperative hospital stay, and fewer postoperative complications. The median follow-up period was 36 months. During follow-up, 90.5% of patients achieved complete remission. The 5-year disease-free and overall survival rates were 80.4% and 92.6%, respectively. More previous chemotherapy courses and failure to achieve normal β-human chorionic gonadotropin levels postoperatively were predictors of poor prognosis.
Conclusions:
Surgical treatment of lung metastasis is valuable and safe for patients with refractory gestational trophoblastic neoplasia. The minimally invasive video-assisted thoracoscopic approach and wedge resection are recommended.
