Insights
Cidofovir treatment may improve outcomes for juvenile recurrent respiratory papillomatosis (JRRP). Patients receiving cidofovir required less time for treatment until remission compared to surgery alone.
Area of Science:
- Otolaryngology
- Pediatric Oncology
- Virology
Background:
- Juvenile recurrent respiratory papillomatosis (JRRP) is a rare disease often requiring multiple surgeries.
- The efficacy of antiviral treatments like cidofovir for JRRP is not well-established.
- Early onset JRRP is associated with more aggressive disease progression.
Purpose of the Study:
- To identify factors influencing JRRP prognosis.
- To evaluate the effectiveness of cidofovir in eradicating JRRP.
- To compare outcomes between surgical debulking with and without cidofovir injection.
Main Methods:
- Retrospective evaluation of 22 children diagnosed with JRRP.
- Comparison of two groups: surgery alone (Group 1) versus surgery with cidofovir injection (Group 2).
- Correlation analysis of age at diagnosis, Derkay score, and disease outcome; comparison of disease progression between groups.
Main Results:
- Fifteen children achieved disease-free status (8 in Group 2, 7 in Group 1).
- Age and clinical scores were negatively correlated with disease outcome (P<0.05).
- The duration of treatment until remission was significantly shorter in the cidofovir group (Group 2) compared to the surgery-only group (Group 1) (P<0.05).
Conclusions:
- JRRP demonstrates more aggressive behavior in earlier onset cases.
- Cidofovir treatment, in conjunction with surgery, significantly reduces the time to eradicate JRRP compared to surgery alone.
- These findings suggest cidofovir is a valuable therapeutic option for managing JRRP.
Unlabelled:
The efficacy of cidofovir in juvenile recurrent respiratory papillomatosis (JRRP) remains uncertain due to the lack of published case-control studies.
Aim:
To establish factors affecting the progression of JRRP prognosis, and to evaluate cidofovir for eradicating JRRP.
Study Design:
Retrospective.
Methods:
22 children with JRRP were evaluated at a referral center. All children underwent surgical debulking, followed by cidofovir injection (Group 2) or not (Group 1). Age at diagnosis was correlated with the Derkay score and disease outcome. Disease progression was compared between groups 1 and 2.
Results:
fifteen children were considered disease-free; 8 were in Group 2 and 7 in Group 1. Age and total and clinical scores (P<0.05) were negatively correlated. The mean number of surgeries required to control the disease was identical in both groups; the duration of treatment until remission was significantly higher in Group 1 (P<0,05).
Conclusion:
JRRP is more aggressive in earlier onset disease. The duration of treatment was significantly lower in patients treated with cidofovir until eradication of JRRP compared to patients treated with surgery only.
