Pulmonary resection of metastatic lesions from colorectal cancer was performed in 62 patients, and their cumulative 5‐year and 10‐year survival rates were 42% and 22%, respectively. The overall median survival was 24 months. The survival curve decreased even after 5 years after pulmonary resection; four of 13 patients who survived more than 5 years subsequently died of metastatic disease and only two patients survived more than 10 years. The number and size of the pulmonary metastases were significantly correlated with postthoracotomy survival. Solitary metastases less than 3.0 cm in diameter were good indicators of favorable postthoracotomy survival. There were no significant differences in survival based on Dukes' classification or location of the primary lesion. Sex, age, disease‐free interval between the primary tumor and appearance of metastasis, and extent of pulmonary resection had no influence on survival. It is impossible to say from our experience that surgical resection of pulmonary metastases increased the cure rate. Presumably a good 5‐year survival rate after thoracotomy would be a reflection of a length bias caused by the biologic behavior of the metastatic pulmonary lesions.
