Survival and Prognostic Factors of Squamous Cell Carcinoma of the Nasal Vestibule

The goal of this observational study is to learn about survival and prognostic factors in patients who underwent surgical treatment for primary squamous cell carcinoma of the nasal vestibule. The main questions it aims to answer are:what is the prognosis of patients affected by squamous cell carcinoma of the nasal vestibule?are there any specific factors that could influence prognosis?is it possible to elaborate a new staging system, able to overcome the limitations of the currently used ones? Data about patients, tumour and type of surgery performed will be collected. Participants will be followed-up for a minimum 6 months period after surgery.

Inclusion Criteria:diagnosis of squamous cell carcinoma of the nasal vestibuleunderwent upfront surgical treatment with curative intentavailability of clinical and radiological data for cT reassessmentavailability of histological samples for pT reassessmentfollow-up of at least 6 months after surgery.Exclusion Criteria:patients initially referred for disease persistence or recurrencepatients affected by tumour involving the nasal vestibule but originating from other sites (eg. nasal cavities, skin of the nasal pyramid or upper lip)
