Resected pulmonary metastases from colorectal cancer.

A review of 35 patients who, over an 18-year preiod, underwent excision of pulmonary metastases from colorectal cancer, is presented. The cumulative five-year survival rate was 22 per cent, and this was significantly increased where the primary colonic cancer was Dukes' A or B. No difference in survival was found regarding the disease-free interval and the number of metastatic lesions. The follow-up of patients with colorectal cancer should always include yearly chest x-rays; and when metastases developed in the lungs alone, surgery for their removal is recommended.
