Association between human papillomavirus infection and malignant transformation of sinonasal inverted papilloma: A systematic review and meta-analysis

摘要

Purpose: Although sinonasal inverted papilloma malignant transformation has not been entirely understood, some studies have suggested that human papillomavirus acts as a potential oncogenic agent in the progression of sinonasal inverted papilloma to squamous cell carcinoma. The purpose of this study was to assess the association between human papillomavirus infection and sinonasal inverted papilloma transformation, taking also into account human papillomavirus types and their distribution in different geographic areas. Materials and methods: The literature from the last 25 years was examined. The systematic review and meta-analysis were performed according to the PRISMA guidelines. Results: A total of 163 malignant sinonasal inverted papilloma and 961 non-malignant sinonasal inverted papilloma were included in the overall analysis. From this sample it was possible to recognize a statistically significant increase in risk of malignancy of sinonasal inverted papilloma for human papillomavirus infection (OR = 2.43, 95 CI: 1.45-4.08, I2 = 14.0 ). A positive association for patients with high-risk human papillomavirus types was noted (OR = 10.20, 95 CI: 3.66-28.42, I2 = 15.9 ). In all the 3 geographical areas analyzed the presence of high-risk human papillomavirus significantly increased the probability of malignant transformation. Conclusions: High-risk human papillomavirus infection plays a key role in the malignant transformation of sinonasal inverted papilloma and its research during histological examination can be of paramount importance. More prospective studies are needed to help further tease out this association.
