✦ Synopsis

While hepatic resection of metastatic colorectal carcinoma is accepted as effective in selected patients, resection of metastases to other solid organs has not gained wide acceptance. We retrospectively reviewed the records of 49 patients who had resection of isolated pulmonary (1 8 patients) and hepatic (3 1 patients) metastases from the large bowel, comparing diseasefree survival and overall survival. Tumor parameters analyzed included Dukes' stage, deoxyribonucleic acid (DNA) flow cytometry , and number of metastases. Dukes' B and diploid tumors had longer disease-free survival and overall survival than did Dukes' C and aneuploid tumors, though the difference was not significant. Patients with a single lung metastasis had a significantly longer disease-free survival ( P = .02) than did patients with multiple metastases. Mean and median survival were longer in patients with lung metastases. Five-year actuarial survival was 19% for patients with liver metastases and 47% for patients with lung metastases. Resection of isolated pulmonary metastases from the large intestine results in survival comparable to or better than resection of hepatic metastases. An aggressive surgical approach is warranted in patients with isolated resectable pulmonary metastases of colorectal carcinoma.
