INTRODUCTION: Recurrent respiratory papillomatosis is characterized by wart-like lesions of the upper airway and is most frequently caused by human papillomavirus (HPV). The disease has significant impact on quality of life due to potential airway obstruction, dysphonia and the need for serial surgeries. The main objective of this study was to describe patient characteristics and long-term follow-up data in a Danish cohort with the disease.
METHODS: The study was a longitudinal retrospective cohort-study using data from electronic medical records and a pathology database.
RESULTS: A total of 61 adult and four juvenile patients were identified. The male-to-female ratio was 2.4. In the adult population, the mean age at onset was 45 years. The median number of surgeries was four (interquartile range: 2.8). The mean follow-up time was 8.7 years (range: 7 days-30 years). Three cases of malignant transformation were observed. In the juvenile population, the mean age of onset was 8.5 years (range: 3-12 years). The mean follow-up time was 11.5 years (range: 2-23 years), and the number of surgeries per year at risk was one/year. CO2-laser and microdebrider were the surgical techniques usually employed. 43% of histopathologic analyses could detect HPV infection (subtype 6 or 11).
CONCLUSIONS: More males than females suffer from respiratory papillomatosis; age of onset was either in childhood or in mid-life. Use of CO2-laser or microdebrider was the preferred surgical approach in this cohort.
