BACKGROUND: Defining the phenotypes of chronic rhinosinusitis with @entity480 (CRSwNP) with prognosis may lead to delivery of personalized treatment. This study aimed to identify cellular phenotypes of CRSwNP using cluster analysis and define an algorithm for different clusters associated with polyp recurrence. METHODS: Overall, 366 @entity1 with CRSwNP were enrolled in this retrospective analysis. Eighteen variables, including clinical characteristics and tissue/peripheral inflammatory cells assessments, were selected for factor analysis. Unsupervised cluster analysis was performed after variables reduction and standardization and differences in polyp recurrence during follow-up for a minimum of 24 months were analysed among clusters. Discriminant analysis was further used to develop a clinically useful algorithm for predicting clustering. RESULTS: Five phenotypic clusters were identified. Clusters 1 and 2 were plasma cell-dominant and lymphocyte-dominant phenotypes, respectively. Cluster 3 revealed a mixed inflammatory pattern. Cluster 4 was characterized by infiltration of predominantly neutrophils. Cluster 5 was characterized by a marked tissue @entity1712 and highest recurrence rate of 98.5%. The clinical algorithm predicted clustering with 93.7% accuracy. CONCLUSIONS: Chinese CRSwNP @entity1 may be classified into five phenotypes with different polyp recurrence rates, based on the presence of predominantly plasma cells, lymphocytes, neutrophils, eosinophils or mixed inflammatory cells in @entity1127 .
