Pulmonary metastasis from carcinoma of the uterine cervix

Of 817 patients with carcinoma of the uterine cervix that were treated and followed-up, 50 (6.1%) developed pulmonary metastases. The incidence of pulmonary metastasis was 3.2% in stage I, 5.0% in stage II, 9.4% in stage III, and 20.9% in stage IV disease. The incidence of pulmonary metastasis in patients with adenocarcinoma and undifferentiated carcinoma was higher. Of the patients in whom lung metastases were detected, 41.7% had no symptoms; 96% was diagnosed within 2 years from the initiation of treatment. All patients had abnormal shadows in chest X rays. We recommend that chest X rays be obtained every 2 months within the 8 months after treatment and every 6 months thereafter. Eighty-one percent of the patients had local recurrence or other distant metastatic lesions. The main treatment for these patients was chemotherapy, and CAP was effective for the patients with adenocarcinoma. Surgical resection of the pulmonary lesion may be an effective treatment for the patients who have no lesions in other sites.
