Surgical resection continues to be a mainstay of curative treatment of patients with non-small cell lung cancers stages I - III and some small cell lung cancers. Reported rates of complications and mortality vary considerably. Therefore, a thorough and comprehensive preoperative evaluation of lung cancer patients is crucial in order to select appropriate surgical candidates and to determine their individual risk, including the extent of resection possible. Following available data and
guidelines, such evaluation should include: ECOG-scoring, cardiac risk assessment, cerebrovascular assessment, pulmonary risk assessment, including split function analysis, and additional initiation or adjustment of treatment where appropriate; in patients aged ≥ 70 years: functional scoring (IADL). Risk stratification results in three groups: patients at low risk for complications and mortality, patients at increased risk, and patients who usually are not candidates for surgical resection. Finally, in order to support autonomous decisions of patients on optimal treatment based on defined risks, physicians must be familiar with values and preferences of patients as well as their familial and social situation.
