Pdf Summary

In this study, the researchers examined the postoperative course of patients who underwent surgery for lung cancer and had preserved ratio impaired spirometry (PRISm), a spirometric pattern characterized by reduced FEV1 and FVC but a normal FEV1/FVC ratio. The purpose of the study was to evaluate postoperative complications and survival for these patients.<br /><br />The medical records of 1807 lung cancer patients who underwent segmentectomy or more extensive surgery at the Shizuoka Cancer Center in Japan between 2015 and 2022 were reviewed. The patients were classified into different lung function categories based on their spirometry results: normal spirometry, PRISm, and airflow limitation (AFL) based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria.<br /><br />The researchers found that postoperative complications were more common in smokers and AFL cases, while PRISm cases did not have a high rate of complications. However, the postoperative survival of PRISm patients was similar to AFL patients and worse than patients with normal lung function.<br /><br />The study concluded that PRISm can be considered a preliminary step towards airflow limitation and further research is needed to understand perioperative interventions for PRISm patients.<br /><br />Overall, this study provides insight into the postoperative course of surgically resected lung cancer patients with PRISm and highlights the importance of considering lung function status when evaluating postoperative complications and prognosis in these patients.
