This protocol applies to nasal cavity cancer occurring in the setting of inverting papilloma — a low-grade benign tumour of the nasal cavity with a recognised tendency to recur and, in a subset of cases, to undergo malignant transformation. These tumour characteristics directly shape the clinical management approach.
Management in this setting centres on a surgical strategy directed at cases where prior intervention has not achieved adequate disease control. The complete evidence-based algorithm — including the full range of options, decision criteria, and clinical considerations — is available in the structured protocol below.
