Abstract Introduction Clinical and pathological staging plays an important role on the prognosis of head and neck cancer (HNC) patients. Objective The present study aims to compare clinical and pathological T, N and overall staging in patients with HNC, to identify factors associated with these discrepancies, and to analyze and compare survival or disease-free survival in staging disagreements. Methods Retrospective cohort including every patient submitted to neck dissection from January 2010 to December 2020 in the department of Otorhinolaryngology of a tertiary hospital center. Results A total of 79 patients were analyzed; their mean age was 58.52 ± 13.15 years old and 88.9% were male. Assessing overall staging, discrepancies were noted in 53% (36.4% upstaging and 16.6% downstaging) and were significantly associated with clinical overall staging (p = 0.006). Regarding T staging, differences were noted in 45.5% (30.3% upstaging and 15.2% downstaging) and were significantly associated with imaging modality (p = 0.016), clinical T staging (p = 0.049), and histology (p = 0.017). Discrepancies in N staging were noted in 38% (25.3% upstaging and 12.7% downstaging) and were significantly associated with age (p = 0.013), clinical N staging (p < 0.001), and presence of extranodal invasion (p < 0.001). Both in Overall, T, and N staging, the aforementioned disagreements were not associated with either higher mortality or higher disease relapse. Conclusion Overall, T, and N staging disagree in an important number of cases, and the overall stage can disagree in up to 53% of the cases. These disagreements do not seem to influence overall and disease-free survival.

RESUMO INTRODUÇÃO: A rinossinusite constitui um importante problema de saúde, com interferência significante na vida pessoal, e sócio-profissional dos pacientes. Este estudo apresenta o processo de validação da versão do RhinoQOL na língua portuguesa para ser usado em pacientes portadores de rinossinusite crônica. OBJETIVO: Demonstrar que a versão do RhinoQOL na língua portuguesa é tão válida quanto a versão inglesa na medição dos sintomas e qualidade de vida dos pacientes com rinossinusite crônica. MÉTODO: A versão em português do RhinoQOL foi aplicada consecutivamente a 58 pacientes com rinossinusite crônica, com e sem pólipos nasais, previamente à cirurgia endoscópica nasal, tendo sido reavaliados aos 3 meses de pós-operatório. Análise estatística foi realizada para determinar as suas propriedades psicométricas. RESULTADO: A validade de conteúdo foi confirmada por uma consistência interna similar à do questionário original, para cada sub-escala, e por uma forte correlação entre cada item e o score total. A aplicação do questionário foi fácil e rápida (5,5 min). Aos 3 meses, verificou-se uma redução significativa dos scores de todas as sub-escalas, indicando melhoria clínica, com um tamanho de efeito considerado grande. CONCLUSÃO: Este estudo fornece um questionário que é equivalente à versão original, com boa sensibilidade à mudança, o que pode ser especialmente útil na medição do impacto da cirurgia.

ABSTRACT INTRODUCTION: Rhinosinusitis constitutes an important health problem, with significant interference in personal, professional, and social functioning. This study presents the validation process of the Portuguese version of the RhinoQOL, to be used as a routine procedure in the assessment of patients with chronic rhinosinusitis. OBJECTIVE: To demonstrate that the Portuguese version of the RhinoQOL is as valid as the English version to measure symptoms and health-related quality of life in chronic rhinosinusitis. METHODS: The Portuguese version of the RhinoQOL was administered consecutively to 58 patients with chronic rhinosinusitis with and without nasal polyps, assessed for endoscopic sinus surgery. A follow-up survey was completed three months after surgery. Statistical analysis was performed to determine its psychometric properties. RESULTS: Face and content validity were confirmed by similar internal consistency as the original questionnaire for each sub-scale, and strong correlation between individual items and total score. The questionnaire was easy and quick to administer (5.5 min). At three months, there was a significant decrease from baseline for all sub-scale scores, indicating clinical improvement, with an effect size considered as large. CONCLUSION: This study provides a questionnaire that is equivalent to the original English version, with good responsiveness to change, which can be especially valuable to measure the outcome of surgery.
