Abstract

BACKGROUND: This study aims to describe the factors associated with dysplastic changes in sinonasal inverted papilloma (SIP) including somatic EGFR mutation, FoxM1 expression, HPV status, and their association with dysplastic changes. METHODS: A cross-sectional, analytical study was conducted comprising 34 samples of histologically-confirmed diagnosis of SIP. The samples were further grouped into 2 groups: 20 samples without associated dysplastic changes, and 14 samples with associated dysplastic changes. The numbers of FoxM1 positively-expressed cells, EGFR mutation, and HPV status were compared among two groups using appropriate comparative statistics. RESULTS: There was statistically-significant difference of FoxM1 expression between SIP and SIP with dysplasia (10% vs 100%; p<0.001). EGFR mutation was identified in 6 samples (30.0%) of the SIP and 5 samples (35.7%) of SIP with dysplasia. No difference of EGFR mutant proportion among two groups. HPV DNA was detected in 5 samples (25.0%) of SIP versus 9 samples (64.3%) of SIP with dysplasia. There was significant difference of HPV status among two groups (p=0.022). The high-risk subtypes were found in most HPV positive samples (57.1%), while low-risk subtypes and out panel subtypes were found 14.3% and 21.4%, respectively. CONCLUSIONS: FoxM1 was overexpressed in SIP with malignant transformation. FoxM1 along with HPV status is associated with dysplastic changes in the SIP. FoxM1 immunostaining is potential to be a biomarker of malignant transformation in SIP.
