Objectives/Hypothesis
The aim of the present study is to validate and compare four of the most widely used staging systems for juvenile angiofibroma on a homogeneous cohort of patients.
Study Design
Retrospective case series.
Methods
A retrospective review of patients treated with endoscopic or endoscopic-assisted surgical resection between 1999 and 2020 was carried out. Each case was classified according to the following staging systems: Andrews-Fisch (1989), Radkowski (1996), University of Pittsburgh Medical Center (2010), and Janakiram (2017). Spearman's rank correlation test and areas under the curve of receiver operator curves were used to assess the correlation between outcomes of interests (blood loss, surgical time, need for transfusion, and persistence of disease) and stage of disease.
Results
Seventy-nine patients were included, with a median follow-up time of 25 months (range 12–127 months). Median surgical time was 217 minutes (range 52–625). Median blood loss was 500 mL (range 40–5200) and 27 patients (34.2%) required blood transfusions. Seven patients (8.9%) showed persistence of disease. All classification systems showed a similar association with blood loss, surgical time, persistence of disease, and need for transfusion.
Conclusions
Involvement of the infratemporal fossa and intracranial extension was identified as red flags for surgical planning and preoperative counseling, as associated with increased risk for transfusion and persistent/recurrent disease, respectively. No classification system was found to be better than the others in predicting the most important outcomes. Therefore, the simplest and most easily applicable system would be the preferred one to be used in clinical practice.
