[Presurgical evaluation of adult thorax-surgery patients with oncologically resectable tumours - a joint recommendation of DGAI, DGT and DGP].

The increasing incidence of malignant lung diseases, neoadjuvant therapies, and the expected detection of operable stages through future lung cancer screening require differentiated preoperative decisions regarding functional operability against the background of an increase in respiratory diseases, especially COPD, but also interstitial lung diseases.Since the postoperative risk of cardiovascular and pulmonary complications after lung resection increases with the extent of lung parenchymal resection and the pre-existing impairment of organ function of the heart, lungs, kidneys, and metabolism, these also require special attention. Given the increasing number of elderly patients over 75 years of age, this also applies to frailty, which represents another key parameter in structured evaluation.
