FiguHigher rate of local recurrence in sinonasal squamous cell carcinoma arising from inverted papilloma compared to de novo tumours

Key Points

• Higher recurrence occurs in sinonasal squamous cell carcinoma derived from inverted papilloma compared to de novo tumours, indicating significant clinical implications.
• Analysis showed that sinonasal squamous cell carcinoma arising from inverted papilloma has notably worse outcomes and higher recurrence rates.
• Clinical evaluation examined recurrence patterns and survival outcomes of sinonasal squamous cell carcinoma subtypes, informing patient management needs.
• Findings support enhanced strategies for clinical decision-making to potentially improve patient outcomes with sinonasal malignancies.
