Indications and extent of elective neck dissection in patients with early stage oral and oropharyngeal carcinoma: nationwide survey in The Netherlands

Background: Different strategies are available for the management of patients with early (i.e. tumour stage one or two) oral or oropharyngeal carcinoma and a clinically negative neck. Material and methods: In 2006, a questionnaire was sent to the eight head and neck cancer centres of the Dutch Head and Neck Oncology Cooperative Group. This questionnaire covered: the factors influencing the decision to perform an elective neck dissection; the neck staging procedure; and the types of neck dissection undertaken. Results: All eight questionnaires were returned completed. Respondents indicated that the site (n = 6), size (n = 7) and thickness (n = 6) of the primary tumour were important in decisions regarding elective neck dissection. Ultrasound-guided fine needle aspiration cytology was the most frequently used diagnostic technique (n = 7). Depending on the site and stage of the primary tumour presented, in the different cases 3-7 of the centres would perform an elective neck dissection. Selective neck dissections (i.e. levels I to III/IV) were more frequently performed than modified radical neck dissections. Conclusion: There was no uniformity regarding management of the clinically negative neck in patients with early stage oral and oropharyngeal carcinoma, within The Netherlands
