Long-term outcomes of juvenile-onset recurrent respiratory papillomatosis

Abstract

Objective: To investigate the adult outcomes of children with juvenile-onset recurrent respiratory papillomatosis via long-term follow-up. Study Design: Retrospective study. Setting: Beijing Tongren Hospital. Participants: The study includes 121 patients with recurrent respiratory papillomatosis. Main outcome and measure: We followed up respiratory papillomatosis patients aged least 14 years and analysed their clinical features based on recurrence-free time. Results: In total, 112 (92.6%) patients underwent three or more operations. The age at initial operation was 4.3 ± 2.9 years; 47.9% (58/121) experienced recurrence and underwent surgical treatment after age 14. At follow-up, 5% (6/121) had died, 41.3% (50/121) had been recurrence-free for 5 years or more (cured group), and 53.7% (65/121) had recurrence in the past 5 years (recurrent group). The age at the last operation was 9.2 ± 4.6 years in the cured group. The overall operation frequency was higher in the recurrence group than in the cured group (17.8 ± 11.9 vs 8.7 ± 6.5). Additionally, the human papillomavirus (HPV) infection and tracheal dissemination rates were higher in the recurrence group than in the cured group (90.8% [59/65] vs 54.0% [27/50] and 26.2% [17/65] vs 10% [5/50], respectively). Conclusion: The mortality rate for juvenile-onset recurrent respiratory papillomatosis is 5%. Approximately 50% of children experience recurrence and require repeated operations in adulthood. No significant difference in sex, age at initial operation or adjuvant therapy between the cured and recurrent groups was observed; however, significant between-group differences were found in overall operation frequency, aggressive disease, tracheal dissemination of papilloma, and HPV infection.
