Both risks are lower in the last period compared with the 2 previous periods. This temporal trend is consistent with the mortality and morbidity figures reported by the ESTS in their annual reports.<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">1</span></a></p><p id="par0095" class="elsevierStylePara elsevierViewall">The prevalence of variables that influence the risk of death and cardiopulmonary complications has also changed over time. Patients undergoing surgery in the last 2 years were older than in the 2 preceding periods, probably as a result of increased life expectancy of the population. Age is considered by some authors to be an important risk factor for morbidity after lung resection. Patients older than 70 years are more than twice as likely to develop complications after lung resection compared with younger patients.<a class="elsevierStyleCrossRefs" href="#bib0105"><span class="elsevierStyleSup">3–5</span></a> However, Ogawa et al.<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">6</span></a> showed that postoperative complications in elderly patients with lung cancer were independent of age, and Stamenovic et al.<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">7</span></a> found that patients older than 80 years did not have a higher risk of developing complications after lung resection than patients in their 70s. Nevertheless, it is important to remember that, in general, there is a selection bias when evaluating octogenarian patients.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">8</span></a> In any case, the average age of patients undergoing lung resection has increased over time without increasing the risk of death and complications, although it should be pointed out that the average age of patients in the third period barely reaches 67 years.</p><p id="par0100" class="elsevierStylePara elsevierViewall">Life expectancy has increased in parallel with the prevalence of comorbidities. Thus, for example, the percentage of patients with a history of CVA and CKD has increased in the last 2 periods compared with the first. Improved management of these diseases has most likely delayed the increase of associated morbidity. CD and BMI, however, have not changed significantly over time. Wang et al.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">4</span></a> found that age (70 years or older) and ppoFEV1% (70% or lower) combined with CD were independent prognostic factors for major postoperative complications. According to our results, ppoFEV1% has increased over time, especially when we compare the last 2 periods with the first. This finding may be explained by the decline in the number of pneumonectomies performed in the last 2 periods.</p><p id="par0105" class="elsevierStylePara elsevierViewall">Surgical practices have also evolved over time: only 4% of the procedures performed in the last period were pneumonectomies. Pneumonectomy continues to be a high-risk procedure that is associated with high rates of mortality and morbidity.<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">9</span></a> For this reason, various strategies aimed at preserving the parenchyma have been developed and widely adopted, with the dual objective of ensuring complete resection of the tumor while preserving lung function. As a result, the number of pneumonectomies has fallen dramatically, a trend that is due, among other factors, to an increase in the number of bronchoplastic resections performed and improvements in early detection. These factors were not analyzed in this study.</p><p id="par0110" class="elsevierStylePara elsevierViewall">Fewer extended resections were performed in recent years, probably also due to earlier diagnosis and treatment of lung cancers. Our results show a rate of 8.6% of extended resections in the last 2 years, comparable to the percentage given in the annual ESTS report of 2018.<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">1</span></a> A study by Berry et al.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">5</span></a> underlines the importance of extended resections and thoracotomy as relevant risk factors for morbidity after lung resection surgery.
