Background:
Sinonasal inverted papillomas (IPs) can be associated synchronously or metachronously to invasive squamous cell carcinoma (SCC) in 5% to 10% of cases. The purposes of the present study were to analyze the outcomes of patients with sinonasal SCC arising from inverted papilloma (IP-SCC) treated through an endoscopic approach and review the pertinent literature.
Methods:
The medical records of all patients treated for IP-SCC between 1997 and 2014 at 2 referral centers following a uniform policy were retrospectively analyzed.
Results:
Thirty-four patients fulfilled the inclusion criteria. The 5-year overall survival (OS), disease-specific survival (DFS), and recurrence-free survival (RFS) rates were 66.8 ± 0.99%, 71.2 ± 0.96%, and 73.1 ± 0.82%, respectively. Multivariate analysis revealed that the advanced pT classification (pT3 or greater), the high-grade of tumoral differentiation, the cranioendoscopic approach, and the recurrence of disease impacted negatively on survival rates.
Conclusion:
The endoscopic approach provides encouraging oncologic outcomes for sinonasal IP-SCC, comparable to those observed with traditional external approaches while minimizing morbidity for patients. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1708-1716, 2016.
