Prevalence of dysplasia in juvenile-onset recurrent respiratory papillomatosis



Prevalence of dysplasia in juvenile-onset recurrent respiratory papillomatosis



Archives of Otolaryngology--Head and Neck Surgery 136(1): 7-11



To quantify the prevalence of dysplasia and to evaluate the impact of use of cidofovir in recurrent respiratory papilloma biopsy specimens obtained from a pediatric population. Retrospective review of patient medical records and histopathologic test results from January 1, 1998, through December 31, 2008. Children's Hospital of Wisconsin. Patients with a history of operation treated for recurrent respiratory papillomatosis. The presence or absence of dysplasia identified in a papilloma specimen and patient characteristics, such as age of initial presentation, number of operations, tobacco exposure, treatment for reflux, and use of cidofovir, were quantified. Treatment for recurrent respiratory papillomatosis was identified in 21 patients. Age at initial diagnosis ranged from 8 months to 14 years. A total of 123 recurrent respiratory papillomatosis specimens in 20 patients were identified. Dysplasia was seen in less than 1% of samples (1/123), which represents 5% of total patients. Seven patients (35%) received cidofovir treatment and none of them developed dysplasia. These data demonstrate a lack of correlation between cidofovir treatment and dysplasia, with the P value being nonsignificant (Fisher exact test, P=.4). Dysplasia is a rare event in pediatric recurrent respiratory papillomatosis, and there does not appear to be an association between the use of cidofovir and dysplastic changes.
