RESUMEN
INTRODUCTION: Head and neck squamous cell carcinomas (HNSCC) are the most common malignancies in the head and neck. Previous studies have shown discrepancies in clinical and pathological staging, with a significant number of head and neck cancer patients who were not correctly staged. This has important implications regarding the treatment and prognosis of these patients. The aim of this study was to analyze potential disagreements in clinical and pathological staging in patients with head and neck cancer who underwent elective neck dissection. METHODS: A retrospective study of patients with squamous cell carcinoma of the head and neck, who underwent elective neck dissection, between January 2018 and December 2020. RESULTS: We analyzed 87 patients, with an average age of 64 ± 10.05 years, of whom 96.6% were male. The primary tumor location was the glottis (31%), oropharynx (26.4%), hypopharynx (19.5%), supraglottis (11.5%), and oral cavity (11.5%). In 87.3% there was a history of smoking and/or drinking. Pathological N (pN) staging was higher than clinical staging in 34.3% of patients (N1 in 22.9%; N2 in 8%; N3 in 3.4%). There were no significant differences between the number of nodes removed and the pN staging. However, there was a significant survival difference in patients with>15 nodes removed (p=0.05). There was also a significant difference in patients with pN up-staging regarding survival (p=0.005). Pathological T staging was different from clinical T staging (p<0.05), with an up-staging in 18.4% of the patients and a down-staging in 14.9%, without significant differences regarding survival or recurrence (p>0.05). Adjuvant treatment with radiotherapy was performed in 41.4% and with chemo-radiotherapy in 13.8% of the patients. Locoregional recurrence occurred in 17.5%. CONCLUSION: This study revealed that clinical and pathological N staging after elective neck dissection disagreed in a substantial number of patients, with pathological upstaging and significant differences regarding survival. With relation to T staging, there were no significant differences regarding survival. We should be aware of staging disagreements since they can have significant implications on the treatment and prognosis of cancer patients.
RESUMEN
Cerebral venous sinus thrombosis in children is a rare complication of acute mastoiditis that can potentially be fatal. Clinical expertise is essential for early diagnosis and management due to its subtle course. We present the first known case of paediatric acute mastoiditis with venous sinus thrombosis caused by Shewanella algae and Actinomyces europaeus . A 17-year-old male presented clinical signs of right acute otitis media and mastoiditis. Brain computed tomography showed mastoid opacification, cerebral sinus thrombosis and an extradural collection. Microbiology revealed the presence of S. algae and A. europaeus . A multidisciplinary approach combining medical and surgical treatment allowed the patient to make a full recovery.
