Salvage surgery in recurrent sinonasal cancers: Proposal for a prognostic model based on clinicopathologic and treatment-related parameters.

Background: Evidence on survival and major prognosticators after salvage surgery in recurrent sinonasal cancers (SNC) is limited.

Methods: A retrospective, single-center study of recurrent SNC treated with salvage surgery between 1997 and 2019 was conducted. Univariate and multivariable analyses were performed to define a prognostic score for overall survival (OS).
