Resection of Lung Cancer in Old Patients - Does Demographic Change Cause a Rethink?

Due to the demographic change prevailing in Germany, the age pyramid is shifting more and more upwards. According to the WHO, a patient over the age of 75 is considered to be old. Whether or not and to what extent an old patient can tolerate thoracic surgery purely based on his age and comorbidities remains unclear. Under most circumstances the surgeon's experience seems to be crucial in this decision. PATIENTS AND METHODS:  The data analysis included data from 01. 2016-01. 2018 based on the German Thorax Register (Project ID: 2017-03), which was set up under the patronage of the German Society for Anesthesiology and Intensive Care Medicine (DGAI) and the German Society for Thoracic Surgery (DGT). A total of 1357 patients were included, 658 patients had histologically proven lung cancer stage I-II. These were divided into three groups according to their age; group I (< 65 years), group II (65- ≤ 75) years and group III (> 75 years). We were able to show that group III had essentially no increased postoperative complication rates (all = 48.00 %; group I = 40.90 %; group II = 53.00 %; group III = 52.90 %) and even performed better than group II (65 to ≤ 75) regarding pulmonary complications. (postoperative pneumonia group II = 19.20 %, group III = 12.90 %) The mortality was lowest in patients who were operated on in centers of the German Thorax Register (all = 1.70 %, group I = 1.90 %; group II = 1.70 %; group III = 1.30 %), compared to national german average. (all = 1.99 %; group I = 1.23 %; group II = 2.18 %; group III = 3.78 %) In particular, patients of group III showed the greatest difference. Furthermore, we saw that the majority of anatomical resections performed in centers of the German Thorax Register were resected by VATS (Video-assisted Thoracoscopic Surgery) as opposed to patients operated on in hospitals not affiliated with the German Thorax Register. DISCUSSION:  Considering these results, the question arises whether in Germany all old patients were treated according to current guidelines. Although there is a certain selection bias in group III, operative candidates fit for surgery are operated in the centers of the German Thorax Register. Our results permit us to conclude that this group of patients should be given optimal surgical therapy when indicated. Age alone should not be the sole determining factor in decision-making regarding thoracic surgery.
