ABSTRACT
Colon cancer is a systemic disease in 19% of patients and metastasizes most frequently to the liver and the lung. Survival is enhanced with complete surgical resection of pulmonary metastases. Comprehensive restaging and verification of preoperative fitness must precede resection. The operative approach is dictated by the anatomic location of the metastases, whereas the extent of resection remains a balance between complete removal of metastatic deposits while preserving as much lung parenchyma as possible. The presence of metastatic involvement of hilar and mediastinal lymph nodes is ominous. Multidisciplinary care is highly recommended. An evidence-based algorithm for the identification assessment and treatment of patients with pulmonary metastases is proposed.
