Human Papilloma Virus Infection and Sinonasal Inverted Papilloma Recurrence: A Meta-Analysis

Objective: Prior studies have been contradictory on the role of human papillomavirus (HPV) infection in sinonasal inverted papilloma (SNIP) recurrence. This systematic review and meta-analysis was performed to further evaluate this potential association.

Data sources: PubMed, Embase, and Scopus electronic databases.

Review methods: Case-control studies reporting SNIP recurrence data and HPV status identified by polymerase chain reaction (PCR) and in-situ hybridization (ISH). Meta-analysis was performed to determine pooled odds ratios (ORs) and 95% confidence intervals (CI).

Results: 25 studies were identified including a total of 1116 benign SNIP tumors. A total of 267 SNIP were HPV+, 103 of which were recurrent, and 849 SNIP were HPV-, with 231 being recurrent. The pooled standard OR for recurrence in HPV+ tumors was 2.05 (95% CI: 1.31-3.19). Stratification by low-risk and high-risk HPV subtypes were not statistically significant. The standard OR for SNIP recurrence in low-risk and high-risk HPV+ subtypes were 1.57 (95% CI: 0.98-2.54) and 1.67 (95% CI: 0.98-2.80), respectively.

Conclusion: Infection with HPV may be associated with an increased risk of SNIP recurrence. This increased risk seems to be independent of HPV subtype based on low-risk or high-risk status. However, this correlation was variable among recently published studies requiring additional investigation.
