Oncological outcomes and prognostic factors of squamous cell carcinoma of the upper gingiva and hard palate: a retrospective study.

Purpose: Despite sharing the same staging system as oral cavity cancers, upper gingiva and hard palate (UGHP) squamous cell carcinoma (SCC) have several features that make them a different entity. We aimed to analyze oncological outcomes and adverse prognostic factors of UGHP SCC, and assess an alternate T classification specific to UGHP SCC.

Methods: Retrospective bicentric study including all patients treated by surgery for a UGHP SCC between 2006 and 2021.
