RESUMO

INTRODUCTION: The aim of this study is to assess the impact of lymph node ratio (LNR) and number of positive lymph nodes (NPLN) on mortality and recurrence rates in patients with laryngeal squamous cell carcinoma. MATERIALS AND METHODS: We conducted a retrospective multicenter international study involving 24 Otorhinolaryngology-Head and Neck Surgery divisions. Disease-specific survival (DSS) and disease-free survival (DFS) were evaluated as the main outcomes. The curves for DSS and DFS according to NPLN and LNR were analyzed to identify significant variations and establish specific cut-off values. RESULTS: 2507 patients met the inclusion criteria. DSS and DFS were significantly different in the groups of patients stratified according to LNR and NPLN. The 5-year DSS and DFS based on LNR and NPLN demonstrated an improved ability to stratify patients when compared to pN staging. CONCLUSION: Our data demonstrate the potential prognostic value of NPLN and LNR in laryngeal squamous cell carcinoma.

RESUMO

BACKGROUND AND OBJECTIVE: Ultrasound-guided fine needle aspiration of thyroid nodules with on-site cytological examination may decrease the number of Bethesda categoryI cytologies. The study objective was to evaluate our second-year experience with this procedure to analyze diagnostic efficacy, prevalence, and factors predicting for Bethesda categoryI results. PATIENTS AND METHOD: A retrospective study was conducted of 279 nodules from 233 patients. Ultrasound -guided fine needle aspiration was performed according to the 2015 criteria of the American Thyroid Association. A specimen of each aspiration was air-fixed on site before Diff-Quik staining and microscopic examination to assess its suitability; otherwise, nodule aspiration was repeated up to 5times. Diagnostic efficacy was assessed based on sensitivity and specificity on the cytological categories BethesdaII and BethesdaVI. RESULTS: Diagnostic sensitivity and specificity were both 100%, 5.4% Bethesda categoryI results were obtained, and variables independently associated were age (4.7% increase per year of life) and nodule volume (2.3% increase per each 1mL of volume). CONCLUSIONS: Ultrasound-guided fine needle aspiration of thyroid nodules with on-site cytological examination allows for a high diagnostic efficacy and has been shown to be a highly relevant procedure because it has a very low rate of cytological results of Bethesda categoryI, whose risk has been higher in older subjects and with larger nodules.

RESUMO

Oncogenic osteomalacia is an uncommon syndrome characterized by phosphaturic tumours that produce mineral metabolism abnormalities. Head and neck is the second most frequent location of these tumours. We describe a case of a phosphaturic mesenchymal tumour in the infratemporal fossa that caused oncogenic osteomalacia, resolved by means of surgical excision.
