Surgical resection of pulmonary metastases from colorectal carcinoma. Five-year survival and main prognostic factors.
Between 1986 and 1994, 19 patients underwent pulmonary resection for metastatic colorectal carcinoma. The mean interval between colon resection and appearance of pulmonary metastasis was 41 +/- 21 months. All the patients had no more than two metastases. Wedge resection alone or associated with lobectomy was performed in four patients, lobectomy in ten, and pneumonectomy in five. One patient died within the month after surgery. Mean follow-up was 35 +/- 26 months. The 5-year survival rate was 38.7%. Repeat thoracotomy for recurrent metastases was performed in one patient. The disease-free interval, the size of metastases, the type of pulmonary resection, and the location and the stage of primary cancer had no apparent influence on survival, but the survival rate at 4 years was 25% for patients with high carcinoembryonic antigen (CEA) level versus 80% for those with low CEA level. We conclude that, at least when the number of metastases is less than two, resection of colorectal lung metastasis is safe and effective.
