Management of multiple lung metastases

During the past seven years, 78 patients with multiple lung metastases under went lung resection. Most of the patients with bilateral lung metastases had lung resection through a median sternotomy rather than by bilateral thoracotomies. "Local excision" of the lung lesions was the most frequently used technique in order to preserve as much lung tissue as possible. Sixty-three of the 78 patients received adjuvant therapies following lung resection. Operative mortality was 3.8%. The over-all median survival was 18.3 months. Analysis of the data showed shorter tumor doubling time to be an indicator of poor prognosis, whereas other factors such as disease-free intervals and unilateral vs bilateral metastases did not affect the postoperative survival.
