Purpose: Recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP) is highly variable, reaching 55-60% of cases. Different results about clinical parameters as recurrence predictors has been reported. The aim of this retrospective study was to evaluate CRSwNP recurrence risk after a long-term follow-up (up to 20 years). Moreover, the role of nasal cytology was assessed.Materials and methods: Sixty-one patients who underwent functional endoscopic sinus surgery for CRSwNP were enrolled. Clinical parameters were recorded. Nasal cytology was performed at follow-up examinations. The Kaplan-Meier method was used to obtain the recurrence-free survival curves. The median number of recurrences per year was evaluated.Results: Five- and 10-year recurrence rates were 30.29% and 66.06%, respectively. Median recurrence-free survival was 106 months. Asthma and Aspirin-Exacerbated Respiratory Disease represented predictors of multiple recurrences (p < 0.05). Intranasal steroids were the main treatment to prevent relapses (p < 0.05). Patients with normal cytology at follow-up evaluation had a lower probability to have first recurrence within 10 years (59% of cases), compared to neutrophil or eosinophil infiltrate (100% and 88% of cases, respectively) (p < 0.05).Conclusions: CRSwNP has a high recurrence risk, also more than 10 years after surgery. Nasal cytology may identify subjects with a higher risk of early recurrence.

Abstract

Purpose: Recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP) is highly variable, reaching 55-60% of cases. Different results about clinical parameters as recurrence predictors has been reported. The aim of this retrospective study was to evaluate CRSwNP recurrence risk after a long-term follow-up (up to 20 years). Moreover, the role of nasal cytology was assessed.Materials and methods: Sixty-one patients who underwent functional endoscopic sinus surgery for CRSwNP were enrolled. Clinical parameters were recorded. Nasal cytology was performed at follow-up examinations. The Kaplan-Meier method was used to obtain the recurrence-free survival curves. The median number of recurrences per year was evaluated.Results: Five- and 10-year recurrence rates were 30.29% and 66.06%, respectively. Median recurrence-free survival was 106 months. Asthma and Aspirin-Exacerbated Respiratory Disease represented predictors of multiple recurrences (p < 0.05). Intranasal steroids were the main treatment to prevent relapses (p < 0.05). Patients with normal cytology at follow-up evaluation had a lower probability to have first recurrence within 10 years (59% of cases), compared to neutrophil or eosinophil infiltrate (100% and 88% of cases, respectively) (p < 0.05).Conclusions: CRSwNP has a high recurrence risk, also more than 10 years after surgery. Nasal cytology may identify subjects with a higher risk of early recurrence.
