Purpose: The purpose of this study was to investigate the clinicopathological features of pulmonary metastasis from cervical cancer.
Materials and methods: We reviewed the medical records of 56 patients with cervical cancer who developed pulmonary metastasis after radical hysterectomy, postoperative concurrent chemoradiation or systemic chemotherapy between January 1990 and March 2014.
Results: Fifty-six patients were diagnosed with pulmonary metastasis from cervical cancer. The prevalence of pulmonary metastasis was 3.6%. The mean event-free duration was 12 months. Twelve patients underwent surgical removal of metastatic lesions. The overall survival (OS) of patients with ≤ 3 metastatic lung lesions was 40.7 months, longer than those with > 4 lesions (25 months, p=0.034). The OS of patients who underwent surgical resection was 53.8 months, longer than that of those who did not (p=0.006). In addition, the OS of patients with adjuvant platinum-based chemotherapy was 32.6 months (p=0.027).
Conclusion: In this study, we found that the number of metastatic nodules, surgical resection, and postoperative platinum-based chemotherapy can influence clinical outcome. Further studies on prognostic factors and successful treatment modalities are warranted.
