Pulmonary Resection for Metastases From Colorectal Cancer
2001
Background We reviewed our experience in the surgical treatment of 47 patients with colorectal pulmonary metastases and investigated factors affecting their survival. Method From September 1986 to December 1999, 47 patients underwent 59 thoracotomies for pulmonary metastases from colorectal cancer. Results The median interval between colorectal resection and lung resection (disease-free interval [DFI]) was 33 months. Overall, 5-year survival was 48%. Five-year survival was 51% for patients with solitary metastasis (n = 30), 47% for patients with ipsilateral multiple metastases (n = 11), and 50% for patients with bilateral metastases (n = 6), and there were no significant differences. Five-year survival was 80.8% for 14 patients with DFI of 2 years (p = 0.22). Five-year survival for 11 patients with normal prethoracotomy carcinoembryonic antigen (CEA) levels was 70%, and that for 26 patients with elevated prethoracotomy CEA levels (> 5 ng/mL) was 36% (p Conclusion Pulmonary resection for metastases from colorectal cancer may help prolong survival in selected patients, even with bilateral lesions, recurrent metastasectomy, or extrathoracic disease. Prethoracotomy CEA level was found to be a significant prognostic factor.
