Rea F, Ieva F, Pastorino U, et al. - Despite the postulations that patients might profit from the centralization of high-volume specialized centers, conflicting outcomes have been inscribed on the association between the number of lung resections performed and the long-term, all-cause mortality rates among patients who underwent surgery for lung cancer. Researchers performed a population-based observational study to add to the ongoing debate. They assessed 2,613 patients, all inhabitants of the Lombardy region (Italy), who underwent lung resection for lung cancer from 2012 to 2014 and followed them until 2018. The analysis revealed the 1-year and 5-year survival rates of 90% and 63%, respectively, in this population. A significant, progressive reduction in the mortality risk was observed when the numbers of lung resections performed increased to intermediate and high compared with patients operated on in a low-volume center. Further evidence was thus gained revealing the strong effect of the volume of lung resection cases performed on the long-term survival of lung cancer patients.
