Objective: To assess the need for pulmonary surgery in the treatment of refractory gestational trophoblastic neoplasia with lung metastasis after normalization of serum beta human chorionic gonadotropin (β-hCG) level with salvage chemotherapy.

Materials and methods: A review of medical records of patients with refractory gestational trophoblastic neoplasia who underwent pulmonary surgery and received combined chemotherapy between January 1995 and December 2008 at the Peking Union Medical College Hospital was retrospectively performed. The positive pathologic findings in surgical specimens were defined as trophoblastic cells documented in the specimen. Pathologic findings were reported.

Results: There were 21 patients with preoperative normal β-hCG. Of 21 patients, six (28.6%) had positive pathologic findings. The positive pathologic findings remained at 27.3% in 11 patients who had received no less than two cycles of consolidation chemotherapy before pulmonary surgery. Univariate analysis found that no variables in patient characteristics were associated with pathologic findings. At the median follow-up of 78 months (9-186 months), 85.7% (18 of 21) patients were alive, and no statistical difference was observed in the disease-free survival between the patients with positive and negative pathologic findings. The 5-year overall survival was 72.2%.

Conclusion: Pulmonary surgery is valuable in the treatment of refractory patients with lung metastasis after normalization of serum β-hCG level following salvage chemotherapy, irrespective of viable trophoblasts in surgical specimens. Further study will be necessary to clarify the importance of this observation.
