The aim of this work was to determine the long term results and the prognostic factors after surgical resection of pulmonary metastases from colorectal cancers.


Clinical status after surgery and survival were studied in 101 consecutive patients undergoing lung resection for pulmonary metastases from colorectal carcinoma between 1970 and 1993. Prognostic factors were evaluated according to surgical design. Mean interval between colon resection and lung resection was 44 months. Fifty-nine patients had a solitary lesion, 17 had multiple unilateral lesions and 25 multiple bilateral lesions. Eighteen patients had undergone previous surgery for localized extrapulmonary metastases. A wedge resection was performed in 47 patients, lobectomy or bilobectomy in 40, pneumonectomy in 11 and biopsy in 3.


There was no postoperative mortality and 5-year survival in complete resection was 21%; all patients with incomplete resection or biopsy died within 3 years. Significant prognostic factors were: complete resection, metachronous disease (vs synchronous metastases) and absence of lymph node involvement. The extent of the colorectal disease and the number of resected metastases did not influence prognosis. Survival for patients with resected extrapulmonary disease was not significantly different as compared with patients with only pulmonary metastases. Eleven patients had repeat pulmonary resections, 6 of these patients are currently alive, 3 of them more than 3 years after the second pulmonary resection.


We conclude that resection of colorectal lung metastases is safe and effective, that resectable extrapulmonary disease does not contra-indicate pulmonary resection and that repeat thoracotomy is warranted in selected patients with recurrent lung metastases.
