Surgical resection of pulmonary metastases from colorectal adenocarcinoma.

From 1962 to 1982, 27 patients with pulmonary metastases as the only site of recurrent colorectal carcinoma underwent pulmonary resection at Roswell Park Memorial Institute. Only five of these patients had symptomatic pulmonary lesions. No postoperative mortality occurred. The median survival after pulmonary resection was 27 months. Five patients are alive presently without recurrent colorectal cancer and two patients are alive with recurrent pulmonary metastases. Patients with solitary lesions had a better survival than patients with multiple lesions. The major sites of recurrence following thoracotomy were the lungs and liver.
