The Change of Eosinophils in the Perioperative Period is Significantly Associated with the Prognosis in Patients with Lung Cancer

Abstract

Background: This research focuses on the relationship between the changes in peripheral blood eosinophils (PBEs) perioperatively and the prognosis of lung cancer. Methods: The study included 414 lung cancer patients. These patients were divided into the DOWN (186 patients) and UP (209 patients) groups according to perioperative changes in PBEs. Furthermore, overall survival was compared based on pathological stage, pathological type, tumor location, age and sex. Furthermore, the authors analyzed the prediction of PBEs on the prognosis of chemotherapy. Results: The results showed that lung cancer patients in the DOWN group had a better prognosis (p = 0.0121; 95% CI: 0.6915 [0.5184–0.9224]), and the DOWN group patients with normal postoperative PBEs had a better prognosis (p = 0.0115; 95% CI: 0.6721 [0.4938–0.9148]). Conclusion: Lung cancer patients whose postoperative PBEs were lower than preoperative PBEs had a better prognosis.
