BACKGROUND AND OBJECTIVE: Postoperative pulmonary complications are common and can be fatal in patients with IPF undergoing lung cancer surgery. This study aims to develop a novel scoring system for predicting postoperative pulmonary complications (PPCs) in patients with idiopathic pulmonary fibrosis (IPF) and non-small cell lung cancer (NSCLC) undergoing surgical resection and help establish optimal treatment strategies.
METHODS: We analysed data from 225 patients consisting of two cohorts who were diagnosed with IPF and who underwent curative resection for NSCLC. A scoring system was developed to predict postoperative pulmonary complications based on regression coefficients derived from a multivariable logistic regression model that included the following predictors: age, sex, diabetes, American Society of Anesthesiologists, diffusing capacity, and extent of surgery. Validation of the score was assessed through discrimination and calibration using a separate cohort of 51 patients.
RESULTS: Among the 276 patients analysed, 95 (34%) experienced postoperative pulmonary complications. The final model identified six predictors (with corresponding scores), resulting in a total score of 0-10 points: age ≥ 65 years (1 point), male (1 point), American Society of Anesthesiologists class ≥ 3 (1 point), diabetes (2 point), diffusing capacity ≤ 65% (2 point), and extent of surgery (3 points). The area under the curve for the scoring system was 0.75 (95% CI, 0.69-0.82) in the derivation cohort and 0.73 (95% CI, 0.57-0.88) in the validation cohort.
CONCLUSIONS: This novel scoring system consisting of six easily accessible clinical variables may help predict postoperative pulmonary complications and guide treatment decisions.
