Sinonasal Squamous Cell Carcinoma in the Netherlands: A Population-Based Study of 568 Cases Diagnosed in 2008-2021.

Background: Sinonasal squamous cell carcinoma is known for its rarity and poor prognosis. This study aims to investigate the trends in the incidence of sinonasal squamous cell carcinoma in the Netherlands and to analyze patient characteristics and treatment practices in order to assess their relation with patient outcomes.

Methods: In this prospectively designed population-based cohort study, all patients diagnosed with sinonasal squamous cell carcinoma between 2008 and 2021 in the Netherlands were included.

Sinonasal mucosal melanoma in The Netherlands between 2001 and 2021: a clinical and epidemiological overview of 320 cases.

Purpose: Sinonasal mucosal melanoma (SNMM) is a rare malignancy, characterised by high (local) recurrence rates and poor survival. Comprehensive understanding of tumour etiology is currently lacking, which complicates adequate tumour treatment. Besides examining trends in incidence, this study aims to assess the association between clinical characteristics, treatment practices and patient outcomes, with the objective of establishing a baseline from which SNMM management can be enhanced.

Squamous cell carcinoma of the nasal vestibule in the Netherlands: A clinical and epidemiological review of 763 cases (2008-2021).

Background: Squamous cell carcinoma of the nasal vestibule (SCCNV) is a rare disease, distinctly different in presentation, treatment, and outcome from squamous cell carcinoma (SCC) of the nasal cavity and paranasal sinuses. However, these are often not analyzed separately.

Methods: The Netherlands Cancer Registry (NCR) and pathology reports from the Dutch Nationwide Pathology Databank (PALGA) were used to identify all newly diagnosed SCCNV cases in the Netherlands between 2008 and 2021.
