| Abstract |
Squamous cell carcinoma (SCC) is the most common histological subtype of sinonasal malignancies. Due to non-specific symptoms, sinonasal SCC (SNSCC) is often diagnosed late, posing challenges for management. SNSCC can arise de novo (DN-SCC) or from the malignant transformation of inverted papilloma (IP-SCC). Prior studies have reported inconsistent outcomes comparing these two subtypes (1-6). This study compares recurrence patterns and survival outcomes of DN-SCC and IP-SCC, identifies predictors of recurrence and survival, and aims to inform clinical decision-making and patient counselling. |
