Аннотация
BACKGROUND: The aim of this clinical survey was to assess variations in head and neck squamous cell carcinoma from an unknown primary (HNSCCUP) diagnostic practices across international centers.
METHODS: Clinical practice survey of experts nominated by Head and Neck Cancer International Group (HNCIG) and International Federation of Head and Neck Oncologic Societies (IFHNOS).
RESULTS: Responses were received from 48/49 (97.9%) participants. Outpatient laryngoscopy, CT, and 18-FDG-PETCT were used always or most of the time by 81.3%, 77.1%, and 79.2%, but only 50% regularly used MRI. Unilateral and bilateral tonsillectomy were frequently performed in 41.6% and 27.1% of unilateral nodal disease, and in 18.8% and 52.1% for bilateral disease. Ipsilateral Tongue Base Mucosectomy (TBM) was used always or most of the time in 12.5% of unilateral and 6.3% of bilateral HNSCCUP. Bilateral TBM was used in 10.4% for unilateral and 22.9% for bilateral cancers.
CONCLUSIONS: While there is broad agreement regarding examination and cross-sectional imaging, there are considerable differences in the surgical strategies used to identify occult primaries.
