Predictive Significance of Enhanced Level of Angiogenesis and Tissue Neutrophils for Antrochoanal Polyps Recurrence in Children

Abstract

Background: The pathologic features and potential predictive biomarkers for recurrence of antrochoanal polyps (ACPs) in children are not fully understood. Objectives: To identify the pathologic differences between recurrent and nonrecurrent group and to explore potential clinical markers which predict recurrence of ACPs in children. Material and Methods: A total of 11 recurrent and 21 nonrecurrent ACPs children were enrolled into this retrospect study. Clinical basic information was collected before the first surgery. The counts of vessels were evaluated by hematoxylin–eosin (HE) staining, and CD34 was detected by immunohistochemistry. Meanwhile, the percentage of each tissue inflammatory cells (eosinophils, neutrophils, lymphocytes, and plasma cells) was assessed by HE staining. Results: No statistical significance was observed between the 2 groups in the basic clinical features. Moreover, both the counts of blood vessels and the tissue neutrophils percentage were enhanced significantly in group with ACPs recurrence (P
