Objectives: The lesion distribution of juvenile-onset recurrent respiratory papillomatosis (JORRP) during first-time surgery has been rarely reported. The purpose of this study was to describe the anatomical distribution of papilloma across 25 Derkay sites during initial surgery and to assess the impact of the lesion distribution on disease severity. Methods: Surgical videos and medical records of 106 patients with JORRP (27 aggressive and 79 nonaggressive cases) were retrospectively reviewed. Lesion locations were recorded using Derkay anatomical sites. Logistic regression was used to analyze the effect of the lesion distribution on disease severity. Results: Among the 106 patients, the true vocal cords (90.6% left, 84.0% right) were the most frequently involved site, followed by the false vocal cords (39.6% left, 35.8% right) and the anterior commissure (26.4%). Two patients (1.9%) had tracheal involvement. Patients with false vocal cord involvement (odds ratio [OR] = 3.425, 95% confidence interval [CI] [1.285, 9.132], P =.014) and a younger age at diagnosis (OR =.698, 95% CI [.539,.905], P =.007) were more likely to require more than 4 procedures in the year following first-time surgery. Conclusions: Lesions were most common on the true vocal cords. False vocal cord involvement and a younger age at diagnosis were risk factors for disease severity. [ABSTRACT FROM AUTHOR]

Purpose: To identify the recurrence rate and risk factors for recurrence in patients with juvenile-onset recurrent respiratory papillomatosis (JORRP). Methods: A retrospective review was performed for all JORRP patients who underwent surgery between 2002 and 2019 at our institution. The demographic characteristics and clinical parameters were recorded. Kaplan–Meier estimates and Cox proportional hazards models were used to analyze the rate of recurrence and its risk factors. Results: Our study included 721 patients. The cumulative recurrence rates at 1, 5, and 10 postoperative years following initial surgery were 74.2%, 90.0%, and 94.3%, respectively. Age at diagnosis younger than 4.5 years (HR = 2.380, 95% CI [1.169–4.846], P = 0.017), high Derkay anatomical score (HR = 1.136, 95% CI [1.043–1.236], P = 0.003) and HPV type 11 infection (HR = 2.947, 95% CI [1.326–6.551], P = 0.008) were independent risk factors for recurrence. Adjuvant therapy with interferon was less likely to recur (HR = 0.237, 95% CI [0.091–0.616], P = 0.003). Additionally, gender, tracheotomy, mode of delivery, parity, expression of Ki-67, HPV vaccination, and surgical treatment method were not independently associated with recurrence (P > 0.05). Conclusion: Age at diagnosis younger than 4.5 years, high Derkay anatomical score and HPV type 11 infection were associated with an increased risk for recurrence in patients with JORRP. Adjuvant therapy with interferon may reduce the risk of recurrence. [ABSTRACT FROM AUTHOR]
