Simple Summary: Cancer of the nasal vestibule is thought to be rare. Multiple staging systems exist for the staging of these tumors, which can lead to variability and, therefore, the poor reliability of data. This retrospective study aimed to evaluate these staging systems. One hundred and forty-eight patients with carcinoma of the nasal vestibule were included and re-staged per the available staging systems. Stage distribution varied widely between the four evaluated staging systems. The classification per Bussu et al. had the most balanced allocation of patients amongst the stages. The widespread adoption of a single system and the introduction of a designated topography code for this disease could lead to greater uniformity in data reporting and an improved understanding of the incidence and disease outcome. Further analysis of survival data is needed to assess which classification system is the best suited for nasal vestibule carcinoma. Squamous cell carcinoma of the nasal vestibule is reported to account for less than one percent of all head and neck malignancies. It lacks a designated WHO ICD-O topography code, and multiple systems are available for the staging of this disease, which results in unwanted variability and the subsequent poor reliability of data. The aim of this study was to evaluate the currently available staging systems for cancer of the nasal vestibule, including the recently introduced classification by Bussu et al., which built on Wang's original concept but with clearer anatomical cutoffs. Different staging systems for cancer of the nasal vestibule (UICC nasal cavity, UICC skin cancer of the head and neck, Wang and Bussu et al.) were evaluated via a retrospective analysis of 148 patients. The staging system, per Bussu et al., had the most balanced allocation of patients among the stages. When using the Wang classification as a reference, stage migration occurred less frequently with the Bussu classification. The widespread adoption of a single staging system, as well as the introduction of a designated topography code for cancer of the nasal vestibule, could lead to more uniformity in data reporting and improve an understanding of the incidence and disease outcome. The newly proposed carcinoma of the nasal vestibule classification by Bussu et al. has the potential to improve the staging and allocation among stages. Further analysis of survival data is needed to assess which classification system is best suited for nasal vestibule carcinoma. [ABSTRACT FROM AUTHOR]
