AbstractBased on a review of the literature on resectable lung cancer, pulmonary risk factors before, during and after surgery are discussed. The role of preoperative evaluation in order to determine the patient ability to withstand radical resection is considered. Spirometric indexes as forced expired volume (FEV1) and diffusing lung carbon monoxide capacity (DLCO) should be measured first. If FEV1 and DLCO are > 60% of predicted, patients are at low risk for complications and can undergo pulmonary resection. However, if FEV1 and DLCO are <60% of predicted, further evaluation with a quantitative lung scan is required. If predicted postoperative values for FEV1 and DLCO are >40%, patients can undergo lung resection, otherwise exercise testing is necessary. If the latter shows maximal oxygen uptake (VO2max) of > 15ml/Kg, surgery can be performed; if VO2max is <15 ml/Kg, patients are inoperable.
