The pathologic features and potential predictive biomarkers for recurrence of antrochoanal polyps (ACPs) in children are not fully understood.To identify the pathologic differences between recurrent and nonrecurrent group and to explore potential clinical markers which predict recurrence of ACPs in children.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.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 < .05). According to the receiver operating characteristic curves, the area under the curve for the counts of blood vessels and tissue neutrophils percentage in the prediction of ACPs’ recurrence was 0.779 (P = .0105) and 0.989 (P < .0001) respectively.It was concluded that the counts of blood vessels and the percentage of tissue neutrophils appeared to be potential excellent predictors of ACPs recurrence in children.
