Cancers ORL chez les enfants et adolescents au service d’ORL du CHNU de FANN (A propos de 65 cas)

Abstract

introduction: Every year, more than 400,000 cancers are diagnosed in children and adolescents aged 0-19 [1,3]. In the specific case of head and neck cancer in pediatric patients, the worldwide prevalence is still unknown [7]. New data are therefore needed to improve their management.objectives: To analyse the epidemiological aspects of ENT cancers in patients aged 0-18 years.patients and methods: This was a retrospective, descriptive, single-centre study. It concerned children aged 0-18 years hospitalized for ENT cancer between 1 June 2010 and 30 June 2020. The term «ENT cancer» was used to designate cancers of the VADS, ear, main salivary glands and thyroid, as well as malignant adenopathies of primary appearance and cervico-facial lymphomas.results: A total of 65 patients were identified, representing a frequency of 1.94%. The sex ratio (M/F) was 1.40. The mean age was 13 years, with extremes of 2 and 18 years. 78.46% of patients were over 10 years old. The average consultation time was 7 months, with extremes of 1 month and 60 months, and 63.92% of patients consulted before 6 months. Cervical masses accounted for 69.23% of consultations. No previous history was found in 80% of our patients. The cavum was found in 40% of cases and the hypopharynx in 21.54%. Squamous cell carcinoma was found in 49.23% of cases and lymphoma in 13.85%. Patients presenting at stage T3 or T4 represented 61.54% of cases. Excisional surgery was performed in 6.16% of cases and chemotherapy in 24.61%. 50.77% of patients were lost to follow-up and 43.08% died after an average follow-up of 10 months. Conclusion: ENT cancers in children and adolescents are rare but have a poor prognosis. Improving our technical facilities and raising public awareness could eventually improve the prognosis.
