Abstract

BACKGROUND: The lung is the most common site of metastatic colorectal cancer comprising 10% of all curative resection of colorectal cancer. The reported 5 year survival rate varies among institutions. The purpose of the present study was to present the retrospective analysis of colorectal metastatic lung cancer surgery at our institution. MATERIAL AND METHOD: A total of 61 patients undergoing surgery for metastatic colorectal lung cancer between July 1996 and December 2003 were included in the present study. The stage of the primary colorectal cancer, site of pulmonary metastasis, method of lung resection, the number and size of the metastatic nodules, the recurrence rate, and survival were assessed. RESULT: The 3 and 5 year survival rates were 66% and 41%, respectively. No significant risk factors were identified among the studied variables by either univariate or multivariate analysis. The mean disease free survival rate was 17 months. The most common recurrent site was lung, and among these patients, 3 underwent a second operation and two are still alive.
CONCLUSION
The results of the above data suggest that pulmonary resection of metastatic lung cancer in select patients after curative resection of colon cancer may be a good therapeutic option with the potential for excellent results.
