Background. Recurrent respiratory papillomatosis (RRP) is mainly associated with human papillomavirus (HPV) 6 or HPV11. The purpose of this study was to compare clinical outcome, aggressiveness, and treatment response between HPV6- and HPV11-associated RRP.
Methods. A retrospective cohort of 55 patients with RRP (1974-2012) was used. Surgical interventions (n = 814) were analyzed, and complications scored. HPV6/11-specific polymerase chain reaction (PCR) was performed on RRP biopsies.
Results. Seventy-six percent of patients (42 of 55) were infected with HPV6 and 24% (13 of 55) with HPV11. The HPV11 group had anatomically more widespread disease. The expected number of surgical interventions was higher in the younger age (
Conclusion. Anatomically, HPV11-associated RRP behaves more aggressively. Younger patients with HPV11 and older patients with HPV6 experience a worse clinical course of RRP. (C) 2014 Wiley Periodicals, Inc.
