Abstract
Patients [202 consecutive] who underwent resection of an adenocarcinoma of the colon or rectum from Jan. 1958 to Dec. 1972 were evaluated for the development of a metastatic tumor in the lungs. In the 185 patients who survived the 30 day postoperative period, 30 malignant pulmonary lesions were subsequently recognized. Six of these were a solitary lesion and 24 were multiple lesions. Three of these malignant lesions were proved to be other than metastatic disease. Metastatic adenocarcinoma from the colon or rectum was present in 27 patients, an incidence of 14.5%. Only 4 of these lesions were solitary, 14.8% of the metastatic pulmonary lesions. The solitary metastatic tumors represented an incidence of 2.1% in this patient population, but long term tumor-free survival was possible with appropriate pulmonary resection of the metastatic disease. Periodic roentgenographic examination of the chest, every 4-6 mo. should be an integral part of the postoperative follow-up study carried out on these patients.
