Lung cancer is one of the most frequently diagnosed cancers and the leading cause of cancer‐related deaths worldwide, with an estimated 2 million new cases and 1.76 million deaths per year.It has been reported that segmentectomy is connected with a higher risk of local recurrence.In recent years, some serum blood cell parameters, such as the neutrophil‐lymphocyte ratio (NLR) and platelet‐lymphocyte ratio (PLR), have been reported to be associated with the prognosis of many kinds of malignant tumors.Here, we conducted a study to construct a nomogram using preoperative parameters to identify high risk of recurrence subpopulation in patients with stage IA LUAD. We evaluated the performance of this model in a real‐world patient cohort from a high‐volume cancer center. We also discovered that this model may be valuable to select a better surgery method for the high risk of recurrence subpopulation.
